This page turns pipeline/taxonomy.json into a readable reference. Every field from each entry is preserved. The table shows the whole landscape at a glance; open any entry to see its full detail, adjacent distinctions, co-occurrences, and examples.

Note: key examples used as a basis for taxonomy development were drawn from this article (Spiked Online, April 2026), and from a public exchange in which Rory Stewart challenged Gary Stevenson's credentials as an economist during an interview with Zack Polanski - a live instance of credential-based dismissal - and Stevenson's subsequent rebuttal, which itself provided further illustrative examples.

Straw Man straw_man Aliases misrepresentation, strawman Distinguishing Features The key marker is substitution - a different claim is refuted in place of the original. Distinct from red herring, which introduces irrelevant material rather than misrepresenting the original. Distinguishes From red_herringfalse_equivalencesemantic_dodge Common Co-occurrences appeal_to_ridiculefailure_to_steelmanad_hominem Crossover Debate Terminology None Examples Khan argues that decontextualised true information is harmful. The article restates this as 'Khan thinks true facts are dangerous' - a caricature that is much easier to dismiss. Source: Spiked, UK political media, 2026 Issue: misinformation regulation A politician advocates for means-tested welfare reform. Critics respond: 'They want to punish the poor for being poor.' Source: UK welfare debate, generic Issue: welfare policy Gary Stevenson argues wealth concentration reduces consumer demand. Critics respond: 'He thinks rich people should be banned from making money.' Source: Wealth tax discourse, UK 2024-2026 Issue: wealth tax Proponent of managed immigration argues for a points-based system. Opponent responds: 'They want to close the borders entirely.' Source: UK immigration debate Issue: immigration	non-engagement	psychological_rhetoric	classical	established	misrepresentation, strawman	Arguing against a distorted or weakened version of the opponent's position rather than what they actually said.	4
Equivocation equivocation Aliases semantic slide, ambiguity fallacy Distinguishing Features Unlike semantic dodge, which substitutes a different definition, equivocation exploits a single word's ambiguity within the same argument. The same term does two incompatible jobs. Distinguishes From semantic_dodgeconcept_capture Common Co-occurrences semantic_dodgestraw_man Crossover Debate Terminology None Examples The article uses 'misinformation' sometimes to mean 'deliberate lies', sometimes just 'information a regulator dislikes' - sliding between them to make the concept seem incoherent. Source: UK media regulation debate Issue: misinformation regulation 'Freedom' used to mean both freedom from government interference and freedom from corporate platform censorship - the two imply opposite policy conclusions. Source: Free speech debates, UK/US Issue: free speech 'Growth' slides between GDP growth, wage growth, and productivity growth in a single economic argument - each implies different policies. Source: UK economic debate Issue: economic policy	definition	semantic_manipulation	classical	established	semantic slide, ambiguity fallacy	Using the same word with two different meanings within an argument, allowing the arguer to switch between them without acknowledgement.	3
Semantic Dodge semantic_dodge Aliases definitional substitution, folk definition substitution Distinguishing Features The opponent's actual definition is not engaged - a simpler or colloquial version is attacked instead. Distinct from equivocation, which exploits ambiguity in a single word; this involves replacing a precise definition entirely. Distinguishes From equivocationstraw_man Common Co-occurrences straw_manfailure_to_steelman Crossover Debate Terminology None Examples A report uses a precise academic definition of 'malinformation' (true information deployed to cause harm). The critic argues against 'outright lies' and never engages with the actual definition. Source: UK media policy discourse Issue: misinformation regulation Economist uses 'rent-seeking' in the technical sense (capturing economic surplus without productive contribution). Opponent responds to the colloquial sense of 'looking for a flat to rent'. Source: UK economic commentary Issue: economic policy	definition	semantic_manipulation	classical	established	definitional substitution, folk definition substitution	Substituting your own folk or simplified definition of a term for the technical or operational definition the opponent actually used, then arguing against your version.	2
Ad Hominem ad_hominem Aliases personal attack, character attack Distinguishing Features The attack targets the person, not the argument. Distinct from genetic fallacy, which dismisses based on origin or affiliation rather than character. Both are person-directed but the mechanism differs. Distinguishes From genetic_fallacypoisoning_the_wellattribution_of_intent Common Co-occurrences poisoning_the_wellgenetic_fallacyattribution_of_intentappeal_to_emotion Crossover Debate Terminology None Examples 'Pint-sized culture warrior' applied to Sadiq Khan - designed to pre-poison the reader against the source without engaging their argument. Source: Spiked, UK political media Issue: misinformation regulation Describing Gary Stevenson as 'a trader who got lucky and now lectures economists' without engaging his argument about wealth concentration. Source: UK financial media Issue: wealth tax Calling a climate scientist 'alarmist' rather than addressing the data they cite. Source: UK/US climate debate Issue: climate policy Referring to Keir Starmer's background as a human rights lawyer as evidence he cannot be trusted on crime - dismissing credentials rather than arguments. Source: UK political discourse Issue: crime and justice	source_attack	source_attacks	classical	established	personal attack, character attack	Attacking the character, credibility, or motives of the speaker instead of addressing their argument.	4
Genetic Fallacy genetic_fallacy Aliases origin dismissal, source fallacy Distinguishing Features Dismissal is based on origin or association, not character. Distinct from ad hominem (which attacks person's character) and negative appeal to authority (which invokes absence of credential). The move is: 'this came from X, therefore it is invalid.' Distinguishes From ad_hominemnegative_appeal_to_authoritypoisoning_the_well Common Co-occurrences negative_appeal_to_authorityno_true_scotsmanad_hominem Crossover Debate Terminology None Examples Characterising a climate summit as 'a gathering of the globalist elite' implies conclusions are corrupt by origin - no engagement with what was actually argued. Source: UK/US culture war discourse Issue: climate policy Rory Stewart implying Gary Stevenson's economic analysis is invalid because he is not an active academic - dismissing origin rather than content. Source: UK media, 2024-2026 Issue: wealth tax 'This research was funded by a think tank, so it can't be trusted' - without examining the methodology. Source: UK policy debates Issue: policy research Dismissing a trade union's economic analysis because 'of course unions would say that' - without addressing the argument. Source: UK industrial relations discourse Issue: economic policy	source_attack	source_attacks	classical	established	origin dismissal, source fallacy	Dismissing an argument based on where it comes from - its source, origin, or affiliation - rather than its content.	4
Poisoning the Well poisoning_the_well Aliases pre-emptive discrediting, pre-poisoning Distinguishing Features Comes before the argument, not after. Creates a framing that prejudges the source. Distinct from ad hominem, which attacks after engagement; this sets the stage so no engagement is needed. Distinguishes From ad_hominemgenetic_fallacyattribution_of_intent Common Co-occurrences ad_hominemattribution_of_intentgenetic_fallacyappeal_to_emotion Crossover Debate Terminology None Examples Describing summit speakers as 'snooty globalists who disdain free expression' before quoting them - any claim they make reads as self-interested before it is considered. Source: Spiked, UK political media Issue: misinformation regulation 'Of course the BBC would say that' - used to dismiss any BBC analysis before it is heard. Source: UK media discourse Issue: media bias Introducing an economist who supports wealth taxes as 'a hardline socialist academic' before quoting their data. Source: UK tax debate Issue: wealth tax	source_attack	source_attacks	classical	established	pre-emptive discrediting, pre-poisoning	Pre-emptively discrediting a source before their argument is even presented, so that anything they say is heard through a lens of suspicion.	3
Tone Policing tone_policing Aliases manner objection, respectability politics Distinguishing Features The objection is to manner, not substance. Often used to delegitimise emotionally charged speech from marginalised groups, or to avoid engaging with uncomfortable content by focusing on its packaging. Distinguishes From concern_trollingred_herring Common Co-occurrences concern_trollingred_herringfailure_to_steelman Crossover Debate Terminology None Examples Responding to a Gary Stevenson video about inequality by criticising his 'aggressive' delivery rather than his data. Source: UK economic commentary Issue: wealth tax Dismissing a Black Lives Matter protest by focusing on traffic disruption rather than the policy arguments being made. Source: UK/US political discourse Issue: policing and race Responding to a junior doctor's strike campaign by criticising its 'militant tone' without addressing the pay gap argument. Source: UK NHS dispute 2023 Issue: NHS funding	manipulation	source_attacks	both	established	manner objection, respectability politics	Objecting to how something is said - its tone, framing, or delivery - as a substitute for engaging with what is said.	3
Red Herring red_herring Aliases irrelevant conclusion, ignoratio elenchi Distinguishing Features Material is introduced that is irrelevant to the specific claim being discussed. Different from straw man (which misrepresents the original argument) - the original argument is just abandoned for a different one. Distinguishes From straw_manfalse_equivalence Common Co-occurrences straw_manconcept_captureattribution_of_intentappeal_to_emotion Crossover Debate Terminology None Examples Inserting 'grooming gangs' into a discussion of algorithmic feedback loops - maximally emotive, sidesteps the actual mechanism being described. Source: Spiked, UK political media Issue: misinformation regulation Responding to an argument about wealth concentration by raising crime statistics in deprived areas - related topic, different argument. Source: UK inequality debate Issue: wealth tax In a debate about NHS waiting lists, raising the issue of NHS waste and fraud rather than the funding question asked. Source: UK health policy discourse Issue: NHS funding	non-engagement	psychological_rhetoric	classical	established	irrelevant conclusion, ignoratio elenchi	Introducing material that is emotionally engaging or topically adjacent but does not actually address the argument at hand.	3
False Equivalence false_equivalence Aliases conflation, bothsidesism, false balance Distinguishing Features A comparison is drawn between two things that are not equivalent in scale, mechanism, or moral weight. Distinct from equivocation, which exploits a single word's ambiguity. Distinguishes From equivocationconcept_capturestraw_man Common Co-occurrences concept_capturered_herring Crossover Debate Terminology None Examples Framing the right to hold opinions and the right to spread algorithmically amplified decontextualised information as the same 'freedom of expression'. Source: UK free speech debate Issue: misinformation regulation Treating a government spending £50bn on infrastructure and a household spending £50k as equivalent financial decisions - as if sovereign currency issuers and households face the same constraints. Source: UK economic discourse Issue: economic policy Presenting climate scientists (97% consensus) and climate sceptics as 'two sides' with equal evidential weight. Source: UK/US media Issue: climate policy Presenting the Channel crossings in small boats alongside legal immigration statistics as if they represent the same phenomenon. Source: UK immigration discourse Issue: immigration	manipulation	psychological_rhetoric	classical	established	conflation, bothsidesism, false balance	Treating two meaningfully different things as if they are the same, to borrow the legitimacy of one for the other.	4
Concept Capture concept_capture Aliases co-option, semantic corruption, concept co-option Distinguishing Features A real concern is weaponised to smuggle in a much larger claim. The legitimate version of the concept is used as Trojan horse. Distinct from equivocation - the concept is not ambiguous, it is expanded beyond its logical scope. Distinguishes From equivocationfalse_equivalence Common Co-occurrences false_equivalencestraw_manred_herring Crossover Debate Terminology None Examples The real concern that 'misinformation' could be abused as a political label is used to smuggle in the much larger claim that misinformation as a phenomenon does not exist at all. Source: UK media regulation debate Issue: misinformation regulation 'Free market' used to cover arguments against any form of worker protection - the legitimate concept of market efficiency deployed to resist all regulation. Source: UK/US economic debate Issue: economic policy 'Free speech' used to argue that platforms must host any content - the legitimate concept of freedom from state censorship expanded to cover private platform moderation. Source: UK/US platform regulation debate Issue: free speech	manipulation	semantic_manipulation	both	established	co-option, semantic corruption, concept co-option	Using a legitimate concept (e.g. censorship, free speech) as cover for a broader claim that does not logically follow from it.	3
Appeal to Ridicule appeal_to_ridicule Aliases reductio ad absurdum (misused), mockery as argument Distinguishing Features No counter-argument is made - the position is simply treated as laughable. Distinct from legitimate reductio ad absurdum, which actually traces the logical consequences of a position to demonstrate its incoherence. Distinguishes From straw_manfailure_to_steelman Common Co-occurrences straw_mantone_policing Crossover Debate Terminology None Examples 'So if there are stabbings in London, these are actually the fault of people talking about them online?' - mocking the feedback-loop mechanism without engaging it. Source: UK political media Issue: misinformation regulation Responding to a wealth tax proposal with 'What next, seize people's houses?' - treating the policy as inherently absurd without addressing the evidence. Source: UK tax debate Issue: wealth tax	non-engagement	psychological_rhetoric	classical	established	reductio ad absurdum (misused), mockery as argument	Making a position seem self-evidently absurd without actually disproving it, using sarcasm or hyperbole.	2
Failure to Steelman failure_to_steelman Aliases non-engagement by omission, weak-manning Distinguishing Features A weakened version is chosen, but unlike straw man, it may still be recognisably the opponent's position. The failure is one of intellectual charity - not finding and engaging the best version. Distinguishes From straw_manfailure_to_steelman Common Co-occurrences straw_mancritique_without_alternative Crossover Debate Terminology None Examples Engaging only with the most extreme version of a wealth tax proposal without addressing the more moderate, evidence-based version advocated by mainstream economists. Source: UK tax debate Issue: wealth tax Attacking the most naive version of the case for universal basic income while ignoring the sophisticated macroeconomic arguments for it. Source: UK economic policy debate Issue: economic policy	non-engagement	psychological_rhetoric	classical	established	non-engagement by omission, weak-manning	Engaging only with the weakest form of an argument rather than the strongest, most precise version the opponent could give.	2
Steelmanning steelmanning Aliases principle of charity (applied), steel-manning Distinguishing Features A positive epistemic norm rather than a fallacy. Included in the taxonomy as the reference standard against which failures of engagement are measured. Distinguishes From straw_manfailure_to_steelman Common Co-occurrences None Crossover Debate Terminology None Examples A genuine critique of a misinformation policy would first ask: what is the best possible case for the concept? What evidence supports it? Only then critique it. Source: Normative standard Issue: general	concept	-	classical	established	principle of charity (applied), steel-manning	The intellectual obligation to engage with the strongest, most precise version of an opposing argument before critiquing it. The opposite of straw-manning. Not a fallacy - a standard of intellectual rigour.	1
Argument from Prior argument_from_prior Aliases conclusion-first reasoning, motivated reasoning Distinguishing Features The conclusion drives the argument selection, not the other way around. Identifiable when an outlet or actor consistently reaches the same conclusion regardless of the specific evidence. Distinguishes From red_herringfailure_to_steelman Common Co-occurrences failure_to_steelmancritique_without_alternative Crossover Debate Terminology None Examples Spiked's consistent editorial line means analysis was always going to conclude 'censorship overreach' regardless of what was actually argued. The article is a vessel for a prior, not an inquiry. Source: Spiked, UK political media Issue: misinformation regulation A think tank funded by fossil fuel interests consistently concluding that climate action is economically harmful - regardless of the specific policy examined. Source: UK/US climate policy Issue: climate policy	manipulation	semantic_manipulation	classical	established	conclusion-first reasoning, motivated reasoning	Reaching a conclusion that was fixed before the evidence was examined - using the argument to justify a predetermined position rather than to reach one.	2
Critique Without Alternative critique_without_alternative Aliases purely destructive criticism, demolish without building Distinguishing Features Demolition without construction. The argument identifies problems but proposes no solution - making it impossible to evaluate whether the critique is substantive or merely obstructive. Distinguishes From failure_to_steelmanred_herring Common Co-occurrences failure_to_steelmanstraw_man Crossover Debate Terminology None Examples An article demolishing the concept of 'misinformation' without defining what legitimate use of the term would look like, who should draw the line, or by what criteria. Source: UK media regulation debate Issue: misinformation regulation Opposing every proposed route to NHS reform without offering an alternative model for how to address waiting lists. Source: UK health policy Issue: NHS funding	non-engagement	psychological_rhetoric	classical	established	purely destructive criticism, demolish without building	Attacking a concept, definition, or framework without proposing a coherent alternative - leaving the reader with nothing to replace what was dismantled.	2
Sealioning sealioning Aliases performative good faith, bad faith demand for evidence Distinguishing Features The good faith is a performance. Demands escalate indefinitely - each answer generates a new question. Distinct from genuine Socratic questioning, which accepts answers and builds on them. Distinguishes From concern_trollingfailure_to_steelman Common Co-occurrences concern_trollingattribution_of_intent Crossover Debate Terminology None Examples Demanding ever more specific definitions of 'misinformation' in bad faith - not to understand the concept but to force an infinite regress of justification. Source: UK online political discourse Issue: misinformation regulation Demanding progressively more specific sources for every claim about inequality while accepting no source as sufficient - the goal is delay, not understanding. Source: Twitter/X political discourse Issue: wealth tax	non-engagement	psychological_rhetoric	networked	established	performative good faith, bad faith demand for evidence	Pursuing relentless, performatively polite demands for evidence or clarification - not in genuine search of understanding, but to exhaust the opponent and derail the discussion.	2
Concern Trolling concern_trolling Aliases false concern, trojan criticism Distinguishing Features Formally supportive, substantively undermining. The expressed concern is not genuine - it is a rhetorical vehicle for delegitimisation. Distinguishes From tone_policingattribution_of_intent Common Co-occurrences tone_policingsealioning Crossover Debate Terminology None Examples Framing a critique of immigration rhetoric as 'concern about the risks to community cohesion' while actually using that concern to suppress any discussion of policy failure. Source: UK immigration discourse Issue: immigration Responding to a wealth tax proposal with 'I'm just worried this would drive away investment' without any data - using concern as a rhetorical shield. Source: UK tax debate Issue: wealth tax	manipulation	source_attacks	networked	established	false concern, trojan criticism	Feigning concern about an issue, framing, or approach as a way to undermine a position without openly opposing it - the attack is disguised as friendly advice or genuine worry.	2
Attribution of Intent attribution_of_intent Aliases mind-reading, motive-mongering, mind-reading fallacy Distinguishing Features The motive is asserted as conclusion, not argued. Distinct from ad hominem (which attacks character) and genetic fallacy (which dismisses by origin) - this involves fabricating a hidden agenda. Distinguishes From ad_hominemgenetic_fallacypoisoning_the_well Common Co-occurrences ad_hominempoisoning_the_well Crossover Debate Terminology None Examples 'Khan and his cronies want political narratives censored' - presented as conclusion, but it is an assertion of intent with no direct evidence. Source: Spiked, UK political media Issue: misinformation regulation 'Gary Stevenson only advocates for wealth taxes because he wants to feel morally superior' - motive asserted without evidence, argument avoided. Source: UK economic discourse Issue: wealth tax	source_attack	source_attacks	both	established	mind-reading, motive-mongering, mind-reading fallacy	Asserting the opponent's hidden motive as if it were established fact, then arguing against that motive rather than the actual argument.	2
Malinformation malinformation Aliases weaponised truth, context stripping Distinguishing Features The facts themselves are accurate - the distortion is in the framing, selection, or context. This makes it harder to correct than outright false claims, because the 'fact-check' cannot mark it as false. Distinguishes From misinformationdisinformation Common Co-occurrences red_herringfalse_equivalence Crossover Debate Terminology None Examples Showing a single year of unusually high crime statistics in isolation, without trend context, to support a narrative of terminal decline - each data point is true; the picture is distorted. Source: UK political media Issue: immigration Quoting a scientist's statement accurately but removing the caveats that were central to the original claim. Source: UK/US science communication Issue: general Publishing accurate figures on NHS cost overruns without contextualising them against decade-long underfunding - each number is true; the implication is misleading. Source: UK health policy media Issue: NHS funding	concept	-	networked	established	weaponised truth, context stripping	Information that is factually accurate but deliberately presented out of context, selectively framed, or strategically timed to produce a misleading or harmful impression. Distinct from misinformation (false) and disinformation (deliberately false).	3
Misinformation misinformation Aliases false information (unintentional) Distinguishing Features Intent is absent or irrelevant. The defining feature is factual inaccuracy, not motive. Distinguishes From disinformationmalinformation Common Co-occurrences disinformationmalinformation Crossover Debate Terminology None Examples Sharing a misleading headline about crime rates taken out of context, without knowing it is misleading. Source: Social media, UK Issue: immigration Repeating a false statistic about NHS spending that was widely circulated and believed by the person sharing it. Source: UK political discourse Issue: NHS funding	concept	-	both	established	false information (unintentional)	False or inaccurate information spread regardless of intent - the person sharing it may genuinely believe it to be true. Distinct from disinformation, which involves deliberate deception.	2
Disinformation disinformation Aliases deliberate false information, propaganda Distinguishing Features Intent is the defining feature. The creator knows the information is false or misleading and spreads it anyway. Distinguishes From misinformationmalinformation Common Co-occurrences malinformationattribution_of_intent Crossover Debate Terminology None Examples A coordinated campaign to seed false stories about a political figure's record, knowing the stories are false, designed to shift public opinion. Source: General - documented in multiple UK/US election cycles Issue: electoral integrity Tobacco industry campaigns to manufacture scientific doubt about smoking's health effects - knowingly false claims deployed strategically. Source: Historical - Proctor, Merchants of Doubt Issue: public health	concept	-	both	established	deliberate false information, propaganda	Deliberately false or misleading information created and spread with the intention to deceive. Intent to mislead is the key distinguishing feature from misinformation.	2
No True Scotsman no_true_scotsman Aliases arbitrary definition, moving the goalposts on identity Distinguishing Features An implicit definition is constructed mid-argument specifically to exclude the target. The definition was not established before the argument - it is invented to serve the conclusion. Distinguishes From genetic_fallacyfalse_credential_requirementad_hominem Common Co-occurrences genetic_fallacynegative_appeal_to_authorityfalse_credential_requirement Crossover Debate Terminology None Examples Rory Stewart implying Gary Stevenson is not a 'real economist' because he is not an active academic researcher - an arbitrary credential requirement invented to exclude him. Source: UK media, 2024-2026 Issue: wealth tax 'No real conservative would support net zero' - a definition of 'real conservative' constructed to exclude inconvenient views. Source: UK Conservative party debate Issue: climate policy 'A real patriot would support this policy' - 'real patriot' defined post-hoc to exclude opponents. Source: UK/US political discourse Issue: general	definition	semantic_manipulation	classical	established	arbitrary definition, moving the goalposts on identity	Setting up an arbitrary or unargued definition of who counts as a genuine member of a category, then using that definition to exclude someone whose views are inconvenient.	3
Negative Appeal to Authority negative_appeal_to_authority Aliases inverse ad verecundiam, credential denial Distinguishing Features A claim is dismissed not on its merits but because the speaker lacks a credential that was not necessarily relevant. Different from genetic fallacy (dismissal by origin) - this specifically involves credential absence. Distinguishes From genetic_fallacyad_hominemappeal_to_authorityno_true_scotsman Common Co-occurrences genetic_fallacyno_true_scotsmanfalse_credential_requirement Crossover Debate Terminology None Examples Dismissing Gary Stevenson's economic analysis because he is not a current academic - without addressing his argument about wealth concentration. Source: UK media, Rory Stewart, 2024-2026 Issue: wealth tax 'He is not a climate scientist, so his views on climate policy carry no weight' - dismissal by credential gap rather than argument. Source: UK/US climate debate Issue: climate policy Dismissing an NHS nurse's account of understaffing because she 'is not a health economist'. Source: UK health policy discourse Issue: NHS funding	source_attack	source_attacks	classical	established	inverse ad verecundiam, credential denial	Using the absence of a specific credential or institutional affiliation to dismiss a claim without engaging the claim itself. The inverse of the classical appeal to authority - instead of 'trust X because they have credentials', it is 'dismiss X because they lack credentials'.	3
Appeal to Authority appeal_to_authority Aliases ad verecundiam, argument from authority Distinguishing Features Legitimate appeal to relevant expert consensus is not a fallacy - the fallacy occurs when the authority is irrelevant, misrepresented, or used to shut down engagement with the argument itself. Distinguishes From negative_appeal_to_authoritygenetic_fallacy Common Co-occurrences genetic_fallacynegative_appeal_to_authority Crossover Debate Terminology None Examples Citing a Nobel Prize winner's support for a policy without noting the prize was in an unrelated field. Source: UK policy discourse Issue: economic policy 'The Treasury says it, so it must be right' - without examining the Treasury's modelling assumptions. Source: UK fiscal policy debate Issue: economic policy	source_attack	source_attacks	classical	established	ad verecundiam, argument from authority	Using the credentials, status, or reputation of a source as a substitute for engaging with the argument - implying the claim is valid because of who made it rather than what was said.	2
False Credential Requirement false_credential_requirement Aliases arbitrary gatekeeping by credential, invented qualification requirement Distinguishing Features The credential requirement is constructed for the purpose of exclusion, not derived from any established standard. Often operates alongside No True Scotsman and negative appeal to authority. Distinguishes From no_true_scotsmannegative_appeal_to_authorityarbitrary_gatekeeping Common Co-occurrences no_true_scotsmannegative_appeal_to_authoritygenetic_fallacy Crossover Debate Terminology None Examples Defining 'legitimate economist' as 'active academic researcher' specifically to exclude Gary Stevenson - a criterion not applied to other commentators. Source: UK media, Rory Stewart case Issue: wealth tax Requiring that a politician have 'run a business' before commenting on business regulation - a criterion not established in principle, invented to delegitimise. Source: UK economic debate Issue: economic policy	definition	semantic_manipulation	classical	established	arbitrary gatekeeping by credential, invented qualification requirement	Inventing or selectively applying a credential criterion that was not previously established as the relevant standard, in order to exclude a specific person from a debate.	2
Arbitrary Gatekeeping arbitrary_gatekeeping Aliases entry requirement fallacy Distinguishing Features A mechanism that appears across multiple fallacies (No True Scotsman, false credential requirement, negative appeal to authority). Included as a concept entry to cross-reference these. Distinguishes From no_true_scotsmanfalse_credential_requirementnegative_appeal_to_authority Common Co-occurrences no_true_scotsmanfalse_credential_requirement Crossover Debate Terminology None Examples 'You can't comment on immigration unless you've lived in a high-immigration area' - an unargued entry requirement for the debate. Source: UK immigration discourse Issue: immigration	non-engagement	semantic_manipulation	both	established	entry requirement fallacy	Imposing an unstated or unargued requirement that must be met before an argument can even be considered - effectively blocking engagement without providing reasons.	1
Syllogism syllogism Aliases deductive argument, formal logical structure Distinguishing Features Not a fallacy - the valid form. A syllogism is sound if the premises are true and the logical structure is valid. Most fallacies can be understood as failures of one or both premises, or of the logical connection between them. Distinguishes From None Common Co-occurrences None Crossover Debate Terminology None Examples Valid: All humans are mortal. Socrates is human. Therefore Socrates is mortal. Invalid (Rory Stewart): A legitimate economist is an active academic. Gary Stevenson is not an active academic. Therefore Gary Stevenson is not a legitimate economist. [Premise 1 is unargued; conclusion does not follow even on its own terms.] Source: Logic / UK media case Issue: general	concept	-	classical	established	deductive argument, formal logical structure	A formal deductive argument structure: two premises leading to a conclusion. Included in the taxonomy as the baseline valid structure - the reference point against which logical failures are measured.	1
Agnotology agnotology Aliases manufactured ignorance, culturally produced ignorance Distinguishing Features Distinct from misinformation and disinformation in that the goal is not to assert a false claim but to prevent a true claim from being accepted - to produce and sustain uncertainty rather than to replace one belief with another. Distinguishes From disinformationmisinformationstructured_not_knowing Common Co-occurrences structured_not_knowingdisinformation Crossover Debate Terminology None Examples The tobacco industry's decades-long campaign to produce scientific doubt about the link between smoking and cancer - funding dissenting research specifically to create the impression of contested evidence. Source: Proctor, 'Golden Holocaust'; Oreskes & Conway, 'Merchants of Doubt' Issue: public health Fossil fuel industry funding of climate sceptic research specifically to manufacture the impression that the scientific consensus is contested. Source: US/UK climate discourse Issue: climate policy Media coverage that presents wealth taxation as economically novel or untested - ignoring decades of evidence from countries with functioning wealth taxes. Source: UK tax debate Issue: wealth tax	concept	-	both	established	manufactured ignorance, culturally produced ignorance	The study of culturally produced ignorance - the deliberate manufacture of doubt, uncertainty, or confusion about an established body of knowledge. Coined by Robert Proctor in relation to the tobacco industry's strategic production of scientific uncertainty.	3
Structured Not-Knowing structured_not_knowing Aliases strategic ignorance, epistemic architecture of omission Distinguishing Features The focus is on the absence of questions rather than the presence of false answers. Structures that benefit from not-knowing include those that never commission the research, never ask the question, or systematically fail to collect the evidence that would be needed for accountability. Distinguishes From agnotologydisinformation Common Co-occurrences agnotologymalinformation Crossover Debate Terminology None Examples The lack of systematic UK data on wealth distribution - there is no annual wealth survey equivalent to the income survey, making it structurally harder to argue for wealth taxes. Source: UK fiscal policy Issue: wealth tax International governance structures that require evidence of harm to trigger accountability mechanisms - but systematically fail to fund the collection of that evidence. Source: Discourse Integrity Map / academic IR Issue: general Mainstream media coverage of inequality characterised not by false claims but by particular questions not being asked - what structured not-knowing looks like dressed as normal coverage. Source: UK media analysis Issue: wealth tax	concept	-	both	established	strategic ignorance, epistemic architecture of omission	Ignorance that persists not because information is unavailable but because deliberate mechanisms route around it, discredit it, or decline to ask for it. A structural feature of institutions or discourse, not an individual failure. Related to agnotology but broader - concerns the architecture of what questions get asked, not just the manufacture of doubt.	3
Overton Window overton_window Aliases window of discourse, the Overton range Distinguishing Features A descriptive concept, not a fallacy. Included in the taxonomy because the DIM is built around tracking how arguments move issues across the Overton space. Understanding the window is necessary to interpret what high-volume/low-quality discourse is doing to it. Distinguishes From None Common Co-occurrences None Crossover Debate Terminology None Examples Wealth taxation was outside the UK Overton window in 2019; by 2025 it was being discussed seriously in mainstream policy contexts - partly through the sustained high-quality discourse of figures like Gary Stevenson. Source: UK fiscal policy history Issue: wealth tax The small boats framing of immigration moved from fringe to mainstream partly through high-volume, emotionally charged media coverage rather than substantive policy argument. Source: UK immigration discourse Issue: immigration	concept	-	both	established	window of discourse, the Overton range	The range of ideas considered acceptable or mainstream in public discourse at a given moment. Named after Joseph Overton. Ideas outside the window are considered too radical or fringe to be seriously discussed; ideas inside are considered legitimate policy options.	2
Discourse Quality Score discourse_quality_score Aliases DQS, epistemic quality score Distinguishing Features A DIM-specific measurement concept. Not a fallacy - a scoring instrument. The score is reach-weighted when rolled up from intervention level to issue level. Distinguishes From None Common Co-occurrences None Crossover Debate Terminology None Examples A Spiked article making 12 assertions about misinformation policy, of which 2 cite evidence and 0 engage with counter-evidence, with 3 identified fallacies: DQS approximately 0.18. Source: DIM pilot classification Issue: misinformation regulation	concept	-	both	established	DQS, epistemic quality score	A composite score representing the logical integrity of a public intervention - derived from the ratio of substantive, evidenced claims to total assertions, adjusted for fallacy density and whether counter-evidence is engaged. Range 0–1. DIM-specific metric.	1
Epistemic Reach Index epistemic_reach_index Aliases ERI, reach-weighted quality score Distinguishing Features The novel metric at the centre of the DIM system.

Appeal to Emotion appeal_to_emotion Aliases ad passiones, emotional appeal, pathos manipulation, pathos Distinguishing Features The diagnostic is substitution: the emotional content does the argumentative work. Legitimate rhetoric uses emotion to make a valid argument vivid; appeal to emotion uses it to bypass the argument entirely. Sub-types include appeal to fear, appeal to pity, appeal to flattery, and appeal to disgust.

The emotional response substitutes for - rather than accompanies - a reasoned case.	4
Appeal to Fear appeal_to_fear Aliases ad metum, scare tactics, fear-mongering, argumentum in terrorem Distinguishing Features Distinct from legitimate warning: a genuine warning identifies a specific, evidenced threat and proposes a proportionate response. Appeal to fear inflates the threat, vagues up the evidence, or proposes a pre-determined response regardless of whether the threat justifies it. Distinguishes From appeal_to_emotionmalinformationstraw_man Common Co-occurrences appeal_to_emotionmalinformationfalse_equivalencered_herring Crossover Debate Terminology None Examples If we don't stop the boats, we will lose control of our borders forever - and with them, our national identity.

The fear response does the persuasive work in place of evidence.	4
Appeal to Pity appeal_to_pity Aliases ad misericordiam, sob story fallacy Distinguishing Features The pity is relevant context but not sufficient justification. A person being in a bad situation does not make their argument correct. Distinguishable from legitimate contextualisation: noting that a policy harms a group is evidence; arguing the policy must therefore be wrong without further argument is the fallacy.

Appeal to Flattery appeal_to_flattery Aliases ad captandum, apple polishing, appeal to vanity Distinguishing Features Often operates through implication rather than statement: 'thinking people know that...' or 'anyone with real experience understands...' - the audience is flattered into assent. Distinct from appeal to authority: here the flattery targets the audience, not an external source. Distinguishes From appeal_to_authorityappeal_to_emotionconcern_trolling Common Co-occurrences appeal_to_emotionsealioningpoisoning_the_well Crossover Debate Terminology None Examples 'Smart investors already know that a wealth tax would destroy capital formation - I'm sure you're not one of those who falls for the populist line.'

The flattery does the persuasive work.	4
Appeal to Disgust appeal_to_disgust Aliases ad taedium, yuck factor, wisdom of repugnance Distinguishing Features Leon Kass's 'wisdom of repugnance' is the semi-respectable version - the claim that disgust tracks genuine moral truth. The fallacy version treats the feeling as self-sufficient argument. Common in debates about bioethics, immigration, and social policy where visceral framing is deployed to pre-empt rational analysis.

Context Collapse context_collapse Aliases audience collapse, context stripping, out-group reception Distinguishing Features Not a speaker error in the original argument; a structural property of platform distribution. The original content may be entirely legitimate in its intended context. The distortion is architectural. Distinct from misrepresentation: the content is not changed, but the frame that made it interpretable is stripped. Distinguishes From malinformationstraw_manhashtag_drift Common Co-occurrences hashtag_driftoutrage_cyclemisinformation_latencyviral_authority Crossover Debate Terminology None Examples Internal Labour Party WhatsApp messages shared among activists, written in shorthand with assumed shared context, leaked and reported in national press as straightforward statements of intent.

Coined by Marwick & boyd. The meaning of the content shifts - often radically - in transit.	4
Hashtag Drift hashtag_drift Aliases semantic hijacking, hashtag capture, tag colonisation Distinguishing Features A corpus-level phenomenon: invisible in any single post, visible in aggregate when the volume of out-group usage overtakes in-group usage. Related to concept capture but specific to the hashtag as a coordination mechanism. Distinguishes From context_collapseconcept_captureastroturfing Common Co-occurrences context_collapseastroturfingoutrage_cycleconcept_capture Crossover Debate Terminology None Examples #MeToo progressively adopted by bad-faith actors posting content designed to mock or discredit the movement, diluting signal-to-noise within the tag.

Misinformation Latency misinformation_latency Aliases correction lag, retraction asymmetry, error propagation window Distinguishing Features This is the core mechanism behind the Epistemic Reach Index in the DIM framework - the metric that makes reach-weighting meaningful. A correction published 48 hours after a viral claim has reached a tiny fraction of the original audience. The latency itself is the injury, independent of whether a correction eventually arrives. Distinguishes From misinformationdisinformationoutrage_cycle Common Co-occurrences viral_authorityoutrage_cyclecontext_collapsemisinformation Crossover Debate Terminology None Examples The '£350m for the NHS' Brexit bus claim: the correction that the figure was misleading received orders of magnitude less coverage than the original claim, which had already structured the terms of debate.

Source: UK press, generic - documented by IPSO complaints data Issue: media discourse	networked_mechanic	networked_platform	networked	established	correction lag, retraction asymmetry, error propagation window	The temporal gap between the propagation of a false or misleading claim and the arrival of any correction, during which the error compounds through secondary and tertiary sharing. The original claim reaches a much larger audience than the correction, which arrives too late and into a smaller, already-converted audience.	4
Outrage Cycle outrage_cycle Aliases moral panic loop, platform rage loop, engagement-rage feedback Distinguishing Features Not a property of any individual argument but a property of the platform ecology. Individual bad actors exploit it, but the cycle runs even without intentional manipulation - the incentive structure does the work. Related to but distinct from deliberate astroturfing. Distinguishes From astroturfingecho_baitappeal_to_fear Common Co-occurrences echo_baitappeal_to_fearappeal_to_disgustmisinformation_latencyviral_authority Crossover Debate Terminology None Examples UK culture war flashpoints (statues, pronouns, school curricula) where low-stakes local events are amplified into national crises through successive outrage cycles, each adding rhetorical escalation.

Outrage generates engagement; engagement generates reach; reach recruits more outrage. Accuracy and nuance are structurally penalised.	4
Ratio Panic ratio_panic Aliases the ratio, engagement ratio manipulation, reply-to-like signalling Distinguishing Features Distinct from legitimate criticism: the ratio measures volume of negative response, not quality of argument. Coordinated brigading can manufacture a ratio. The panic version is when speakers preemptively self-censor or retract based on ratio signals rather than the content of responses. Distinguishes From brigadingoutrage_cyclead_hominem Common Co-occurrences brigadingoutrage_cycleastroturfingappeal_to_emotion Crossover Debate Terminology None Examples A politician's tweet on immigration policy receives 10x more replies than likes; media reports this as evidence of 'public backlash' without examining whether the replies contain substantive objections.

A post being 'ratioed' is treated as proof it was wrong. The engagement metric substitutes for the argument.	4
Astroturfing astroturfing Aliases coordinated inauthentic behaviour, fake grassroots, manufactured consensus Distinguishing Features Detectable at scale through network analysis (account age, posting patterns, coordination signatures) but signals can appear in individual texts when the manufactured nature of a campaign is referenced. Distinct from legitimate organised campaigning: transparency and authenticity are the distinguishing features.

Echo Bait echo_bait Aliases tribal signal content, in-group amplification bait, share-farming Distinguishing Features The signal marker is the asymmetry between virality within the in-group and near-zero out-group traction. The content is designed to feel maximally correct to the in-group and maximally offensive or alien to out-groups, foreclosing cross-group dialogue. Distinguishes From outrage_cycleastroturfingappeal_to_flattery Common Co-occurrences outrage_cycleappeal_to_flatteryappeal_to_disgustviral_authority Crossover Debate Terminology None Examples Right-wing Twitter posts listing immigration statistics with no context or policy proposal - not an argument but a signal to co-believers that the author shares their priors.

It functions as an identity signal and tribal rally rather than an argument - its purpose is to circulate within the echo chamber and reinforce group identity, not to persuade.	4
Viral Authority viral_authority Aliases engagement-conferred credibility, reach as expertise, influencer epistemic authority Distinguishing Features Distinct from appeal to authority: the authority is not institutional or credential-based but metrics-based. The metric (views, followers, shares) is treated as a proxy for truth. Partially detectable in single texts when viral performance is cited as justification.

Source: Generic social media discourse Issue: media discourse	networked_mechanic	networked_platform	networked	established	engagement-conferred credibility, reach as expertise, influencer epistemic authority	The attribution of credibility, expertise, or epistemic authority to a claim or speaker on the basis of their reach, engagement, or follower count rather than the quality of their evidence or reasoning. Virality substitutes for validity.	4
Firehose of Falsehood firehose_of_falsehood Aliases information flooding, gish gallop (networked), volume overwhelm, flood the zone Distinguishing Features Distinct from ordinary misinformation: the volume and speed are the weapon, not the content. The goal is not to persuade with a specific false claim but to produce confusion, fatigue, and epistemic paralysis.

Associated with Russian information operations (Rand Corporation, 2016) but now a general-purpose tactic.	4
Dead Cat Strategy dead_cat_strategy Aliases dead cat on the table, distraction injection, news cycle displacement Distinguishing Features The dead cat story need not be believed or defended - the point is that it redirects attention. Partial detectability in single texts when the timing and context of a shocking announcement relative to a preceding damaging story can be established. Fully visible only at corpus/timeline level. Distinguishes From red_herringoutrage_cycleecho_bait Common Co-occurrences outrage_cyclered_herringfirehose_of_falsehood Crossover Debate Terminology None Examples Boris Johnson's 2019 'letterbox' comments: widely interpreted as a strategic distraction from internal Conservative Party pressure - the resulting outrage displaced the original story from the news cycle.

Named by Lynton Crosby: 'If you put a dead cat on the table, everyone will talk about the dead cat.' The strategy exploits media and platform dynamics to force agenda-setting control.	4
Brigading brigading Aliases coordinated pile-on, mass reporting, community raid, organised harassment Distinguishing Features Distinguishable from organic negative response by the coordination pattern: accounts acting in concert, similar timing, often from accounts with similar characteristics. Distinct from astroturfing: brigading typically uses real accounts coordinating, rather than fake accounts simulating grassroots.

Can be politically or ideologically motivated.	4
Prebunking prebunking Aliases inoculation theory, pre-emptive refutation, misinformation inoculation Distinguishing Features Distinct from debunking (which corrects a claim after exposure) and fact-checking (which verifies specific claims). Prebunking targets the technique rather than the specific claim, which makes it more durable - it works even against novel misinformation using familiar tactics. The DIM taxonomy itself functions as a prebunking tool when used educationally.

The prior exposure triggers cognitive resistance that persists when the real manipulation arrives.	4
Bridging bridging Aliases cross-cutting dialogue, bridging capital, bridging-based ranking, deliberative bridging Distinguishing Features The direct structural counter to echo chambers, echo bait, and context collapse. Not mere exposure to opposing views (which evidence shows can entrench positions) but structured engagement that finds common ground. Distinct from false equivalence: bridging requires genuine engagement with substance, not false balance between unequal positions.

In platform contexts, operationalised in bridging-based ranking systems such as Community Notes, which privileges content that achieves agreement across political divides over content that maximises within-group engagement.	4
Deepfake deepfake Aliases deep fake, AI-generated media, synthetic video Distinguishing Features Requires machine learning infrastructure to produce convincingly realistic output. Distinguished from cheapfakes by technical sophistication and from synthetic personas by being media artefacts rather than identities. The liar's dividend - the ability to dismiss authentic footage as fake - is a downstream harm that deepfakes enable even when they are not deployed.

Cheapfake cheapfake Aliases shallowfake, shallow fake, cheap fake, low-tech manipulation, deceptive edit Distinguishing Features Does not require AI or machine learning. The source material is real - the deception is in what surrounds or frames it. Shallowfake is a near-synonym emphasising low-complexity edits. The Nancy Pelosi slow-motion video (2019) - which made her appear impaired - is the canonical political example. Higher volume and lower detectability than deepfakes in practice.

Coined by Paris & Donovan (2019). More prevalent than deepfakes and harder to detect because the underlying media is authentic; only its framing or presentation has been altered.	4
Liar's Dividend liar's_dividend Aliases deepfake dividend, synthetic media deniability Distinguishing Features Operates independently of whether a deepfake is actually deployed - the threat alone does the work. The asymmetry: it is cheap to claim that authentic footage is fake; it is expensive to forensically prove otherwise. This directly compounds misinformation_latency: by the time authenticity is established, the denial has already circulated.

Coined by Chesney & Citron (2018).	4
Synthetic Persona synthetic_persona Aliases deepfake persona, AI-generated identity, sockpuppet (AI-assisted), synthetic identity Distinguishing Features The identity itself is the fabrication, not just the content. Recent research shows LLM-generated personas maintain remarkably stable expression across contexts - enabling sustained influence operations - while this very consistency may enable detection through behavioural analysis. Distinct from astroturfing, which may use real people coordinating; synthetic personas are wholly fabricated.

Distinguished from simple bots by quality and consistency of generated content, and from astroturfing by the technical sophistication of the identity construction - profile images, posting history, expressed personality.	4
AI-Enhanced Influence Operation ai_enhanced_influence_operation Aliases LLM-assisted influence operation, automated influence operation, generative propaganda Distinguishing Features Represents a qualitative shift from previous influence operations because it removes the bottleneck of human content production. Volume, personalisation, and linguistic quality that previously required large human teams can now be achieved with minimal oversight. Distinct from synthetic personas (which are identities) and from astroturfing (which is coordination); AI-enhanced influence operations are characterised by generative content production.

Empirical research (Goldstein et al., 2023) shows almost all LLMs tested produce election disinformation content indistinguishable from human output by evaluators over 50% of the time.	4
Decontextualized Clip decontextualized_clip Aliases out-of-context clip, false context, visual recontextualisation, OOC visual, clip-farming Distinguishing Features Harder to detect than fabricated media precisely because the content is genuine. Fact-checking must establish not falsity of the image but falsity of the claimed context - a more complex and time-consuming process. Directly related to context_collapse: the original context is stripped and a new one substituted.

The media itself is unaltered; only the context that makes it interpretable is stripped or replaced. The visual and multimedia form of malinformation.	4
Dog Whistle dog_whistle Aliases coded language, covert-effect dog whistle, overt-code dog whistle, political dog whistle Distinguishing Features The dual-audience design is the diagnostic feature. Distinct from figleaf: a dog whistle sends a concealed message; a figleaf provides cover for a message that is already partly visible. Distinct from ordinary coded language by the deliberateness of the deniability structure. Distinguishes From figleafjaqingconcept_captureattribution_of_intent Common Co-occurrences figleafjaqingpoisoning_the_wellconcept_capture Crossover Debate Terminology None Examples 'Law and order' in US political discourse - phrase with neutral literal meaning, historically understood by the target in-group as coded reference to suppression of Black political activism.

Formally theorised in philosophy of language and political communication. Two types: overt-code (in-group knows the code, out-group does not) and covert-effect (activates latent attitudes in the in-group without their explicit awareness of the cue).	4
Figleaf figleaf Aliases racial figleaf, deniability phrase, cover statement Distinguishing Features The tell is the structure: a disarming or qualifying phrase immediately preceding or following a loaded claim. Common forms: 'I'm not racist, but...', 'I don't want to spread conspiracy theories, however...', 'Many people are saying...'. The qualifier does not neutralise the claim - it provides deniability while allowing the claim to land. Distinguishes From dog_whistlejaqingconcern_trollingepistemic_cowardice Common Co-occurrences dog_whistlejaqingpoisoning_the_wellattribution_of_intent Crossover Debate Terminology None Examples 'I'm not saying he's corrupt - I'm just asking why these questions keep coming up.'

Distinguished from dog whistle: where a dog whistle conceals the message, a figleaf is needed when the message is already partly visible and needs cover. Coined/theorised by Saul (2018); extended by Tillyris (2024).	4
Motte-and-Bailey motte_and_bailey Aliases motte and bailey doctrine, motte-and-bailey fallacy Distinguishing Features The diagnostic is the alternation - the same speaker making the strong claim in one context and the weak claim when challenged, then returning to the strong claim. Distinct from legitimate qualification or nuance because the speaker denies the alternation is happening. Often exploited in conjunction with sealioning: the bad-faith questioner forces the motte retreat, then the speaker later returns to the bailey. Distinguishes From equivocationsemantic_dodgeepistemic_cowardicestraw_man Common Co-occurrences equivocationsealioningconcern_trollingjaqing Crossover Debate Terminology None Examples Bailey: 'Vaccines cause autism.'

Source: UK gender recognition debate Issue: social policy	non-engagement	semantic_manipulation	both	established	motte and bailey doctrine, motte-and-bailey fallacy	A rhetorical pattern in which a speaker alternates between two positions: an expansive, controversial claim (the bailey - desirable territory but hard to defend) and a modest, obviously defensible fallback (the motte - easy to retreat to under attack). Under criticism they retreat to the motte and defend it as if it were the contested claim; when pressure subsides they return to occupying the bailey. Named by philosopher Nicholas Shackel (2005).	4
JAQing jaqing Aliases just asking questions, JAQing off, pseudosceptic questioning, bullshit question Distinguishing Features The form is interrogative; the function is assertion. The tell: the question contains a presupposition that does the argumentative work. 'Why does X keep covering up Y?' asserts both that X covers up Y and that this is a pattern. Distinct from genuine inquiry by the absence of actual openness to the answer - the questioner already 'knows' the implied answer.

Defined in philosophy of language as posing questions that presuppose the truth of propositions the speaker has no grounds to assert. Now formally discussed in the bullshit-question literature (Springer, 2025).	4
Whataboutism whataboutism Aliases whataboutery, tu quoque (networked), deflection by counter-accusation, false equivalence deflection Distinguishing Features Distinct from legitimate tu quoque (pointing to genuine hypocrisy that is directly relevant): whataboutism's deflection is the point - engaging the criticism is precisely what is being avoided. Platform-native contexts dramatically amplify it because the counter-accusation can circulate independently of the original context. Distinguishes From red_herringfalse_equivalencead_hominemstraw_man Common Co-occurrences red_herringfalse_equivalencedead_cat_strategyoutrage_cycle Crossover Debate Terminology None Examples Challenged about Conservative Party corruption: 'What about Labour's expenses scandal?'

Shifts the burden of proof, changes the subject, and implies the original criticism is hypocritical without addressing it. Originally a Soviet Cold War propaganda technique; now ubiquitous in political discourse globally.	4
Gish Gallop gish_gallop Aliases argument flooding, spreading (debate), point flooding Distinguishing Features Related to firehose_of_falsehood but operates at the level of individual debate rather than mass media distribution. The quantity is the weapon. Distinguished from making many valid points by the deliberate inclusion of weak or irrelevant claims designed to overwhelm rather than inform. Common in live debates, social media threads, and comment flooding.

Named after creationist debater Duane Gish. The strategy exploits the asymmetry between producing false claims (cheap) and rebutting them (expensive). The opponent appears to have 'lost' by failing to address every point, even though many points were not worth addressing.	4
Bothsiderism bothsiderism Aliases both-sidesism, false balance (debate form), false equivalence journalism Distinguishing Features The key is the epistemically unequal positions: both-sidesing the scientific consensus on climate change with fringe denial is bothsiderism. The fallacy misrepresents the evidential landscape by implying two sides have equal standing. Distinct from legitimate acknowledgement of genuine controversy. Related to but separable from false_balance, which is an editorial institutional practice rather than a speaker move. Distinguishes From false_equivalencefalse_balanceepistemic_cowardicestraw_man Common Co-occurrences false_equivalencefalse_balanceepistemic_cowardicewhataboutism Crossover Debate Terminology None Examples Broadcasting a climate scientist and a climate denier as 'the two sides of the debate' - implying equivalence between a near-universal scientific consensus and a fringe position.

Formalised as a distinct meta-argumentative fallacy in 2022 (PMC). Distinguished from journalistic false balance: bothsiderism is a rhetorical move by a participant; false balance is an institutional practice by journalists.	4
Epistemic Cowardice epistemic_cowardice Aliases strategic vagueness, deliberate ambiguity, non-answer Distinguishing Features Active rather than passive - the speaker does say something, but something engineered to avoid commitment. Distinguished from strategic silence by producing speech rather than silence. Distinguished from legitimate qualification by the deliberate suppression of a known or probable position. Documentable as a pattern in public figure communications. Distinguishes From strategic_silencemotte_and_baileysemantic_dodgeconcern_trolling Common Co-occurrences motte_and_baileysemantic_dodgebothsiderismwhataboutism Crossover Debate Terminology None Examples Politician asked directly whether a policy is fair: 'It's a complex issue with many perspectives and we want to listen to all stakeholders before reaching any conclusions.'

The speaker knows or suspects a clearer answer but chooses not to give it. Distinct from genuine uncertainty: the vagueness is motivated, not reflective of actual unknowing.	4
Narrative Laundering narrative_laundering Aliases information laundering, fringe-to-mainstream pipeline, credibility laundering Distinguishing Features Distinct from firehose_of_falsehood: laundering is about provenance and credibility chains, not volume. Distinct from source_hacking: laundering may happen organically through credulous amplification; source hacking involves deliberate concealment of origin. The diagnostic question is whether the claim's credibility has been artificially elevated through chain-of-custody manipulation.

A fringe forum claim becomes a blog post, becomes a think-tank citation, becomes a newspaper question, becomes a political talking point. No single step is necessarily dishonest; the deception is structural. Formalised by Klein (2012); extended to disinformation ecosystems by Starbird et al. (2019).	4
Source Hacking source_hacking Aliases origin laundering, journalist manipulation, strategic media seeding Distinguishing Features Distinct from narrative laundering: source hacking involves deliberate concealment of origin as an operational step; narrative laundering may happen through credulous amplification without intentional concealment.

Coined in a 2019 Harvard Berkman Klein Center report on media manipulation.	4
Data Void data_void Aliases information void, search void, query desert Distinguishing Features The vulnerability is architectural: when a system has no good answer, it will surface whatever answer exists. Manipulators can pre-populate data voids with partisan content, ensuring that when events trigger the query, their framing is the first available. Distinct from information suppression: data voids are exploited rather than created.

Coined and formalised by Golebiewski & boyd (2018/2019, Microsoft Research). Data voids are particularly dangerous for breaking news, newly coined terminology, and deliberately obscure fringe terms.	4
Rage Bait rage_bait Aliases rage farming, outrage farming, anger farming, engagement rage Distinguishing Features Distinct from appeal_to_fear (which uses fear to persuade) and outrage_cycle (which describes the platform dynamic): rage bait is the intentional content-production strategy that exploits the outrage cycle. The content is engineered backward from the anger response - truth and substance are instrumentalised to the extent that they serve the emotional output.

'Rage farming' captures the economic logic: anger is cultivated as a crop, harvested as engagement, sold as advertising inventory. Oxford University Press named 'rage bait' its Word of the Year for 2025, noting its use had tripled in the preceding twelve months.	4
Majority Illusion majority_illusion Aliases local majority illusion, friendship paradox manipulation, false consensus (network) Distinguishing Features Distinct from pluralistic ignorance (a psychological phenomenon) and astroturfing (which is deliberate): the majority illusion can arise structurally from network architecture without any deliberate manipulation. However, it can be deliberately exploited: placing a minority view in the hands of high-degree nodes produces the illusion of majority consensus without creating fake accounts.

False Amplification false_amplification Aliases false diminution, manipulated comment space, opinion climate distortion Distinguishing Features Distinct from majority illusion (which is structural) and from astroturfing (which creates fake accounts): false amplification may involve coordinated real accounts boosting or suppressing content. The output is a systematically distorted picture of public opinion that shapes what others believe the majority thinks.

Epistemic Injustice epistemic_injustice Aliases testimonial injustice, hermeneutical injustice, credibility deficit Distinguishing Features Testimonial injustice maps directly onto genetic_fallacy and negative_appeal_to_authority as the rhetorical mechanisms that enact it. Hermeneutical injustice maps onto concept_capture and agnotology. The contribution of Fricker's framework is to name the harm to the person, not just the fallacy in the argument - it explains why credential attacks on Gary Stevenson cause harm beyond being logically wrong.

Source: UK health policy discourse; documented in critical health studies literature Issue: nhs_funding	concept	-	both	established	testimonial injustice, hermeneutical injustice, credibility deficit	Wrong done to someone specifically in their capacity as a knower. Miranda Fricker (2007) identifies two forms: (1) Testimonial injustice - a speaker's credibility is unjustly deflated due to identity prejudice (gender, race, class), so their testimony is not believed or taken seriously; (2) Hermeneutical injustice - a subject lacks the conceptual resources to understand or articulate their own experience, because the concepts needed don't exist or aren't accessible to them. Both are mechanisms of epistemic harm that operate beneath the level of explicit logical argument.	4
Filter Bubble filter_bubble Aliases algorithmic personalisation bubble, information cocoon (algorithmic) Distinguishing Features Distinct from echo chamber: filter bubbles are algorithmically produced and largely passive - the user does not choose the enclosure. Echo chambers involve active social norm enforcement that excludes outside perspectives. Both produce reduced exposure to disconfirming information but via different mechanisms requiring different interventions. Note: empirical literature debates the strength of filter bubble effects; Pariser's claim is contested by some platform audit studies.

Coined by Eli Pariser (2011). The epistemic harm: the invisible narrowing of information access, producing false confidence that what one encounters represents the information landscape.	4
Echo Chamber echo_chamber Aliases epistemic bubble (active), ideological enclave, opinion silo Distinguishing Features Active social norm enforcement is the diagnostic feature. Echo chambers are partially pre-digital - religious and political enclave communities predate the internet - but digital platforms massively amplify them by reducing the cost of finding and maintaining in-group communities. The hardest epistemic environments to intervene in because adding information is not enough.

Source: UK online community research; ISD and Hope Not Hate investigations Issue: immigration	concept	-	both	established	epistemic bubble (active), ideological enclave, opinion silo	An information environment in which outside perspectives, evidence, or voices are not merely absent (as in a filter bubble) but actively excluded or denigrated - trust is reserved exclusively for insiders, and outside sources are systematically distrusted. C. Thi Nguyen (2020) makes the crucial distinction: filter bubbles result from missing information; echo chambers result from corrupted standards of trust. The remedy differs: you can fix a filter bubble by adding information; you cannot fix an echo chamber that way because the new information will be distrusted.	4
Framing framing Aliases issue framing, news framing, frame analysis Distinguishing Features Distinct from lying and from malinformation: framing operates through selection and salience rather than falsehood. Connects to malinformation as its limit case: malinformation is framing so severe that the selected picture is false even though individual elements are true. Every communication frames; the question is whether the framing is honest or distorting. Distinguishes From malinformationstraw_managenda_settingfalse_equivalence Common Co-occurrences malinformationagenda_settingdog_whistlefalse_balance Crossover Debate Terminology None Examples Immigration described as 'waves' or 'floods' - natural disaster framing that implies overwhelming, uncontrollable force rather than manageable policy decisions.

Source: UK AI regulation discourse, 2023–2026 Issue: ai_regulation	concept	-	classical	established	issue framing, news framing, frame analysis	To frame is to select some aspects of a perceived reality and make them more salient in a communicating text - promoting a particular problem definition, causal interpretation, moral evaluation, or treatment recommendation. Frames are not lies: they select and emphasise genuine aspects of reality. The epistemic harm is in the selection: what is omitted or de-emphasised can produce a systematically false picture even when every element included is true. Canonical definition: Entman (1993). Sociological foundation: Goffman (1974).	4
Motivated Reasoning motivated_reasoning Aliases directional reasoning, confirmation bias (motivated), rationalisation Distinguishing Features Distinct from simple confirmation bias (a cognitive heuristic): motivated reasoning involves directional motivation - not just noticing confirming evidence but actively working toward a pre-determined conclusion. On social media, filter bubbles and echo chambers reduce disconfirming evidence exposure, and the social cost of publicly changing one's mind intensifies motivated reasoning. Distinguishes From backfire_effectepistemic_cowardicefilter_bubble Common Co-occurrences backfire_effectecho_chamberfilter_bubbleepistemic_injustice Crossover Debate Terminology None Examples Voters who support a political party applying rigorous scrutiny to evidence of the party's failures while accepting positive evidence uncritically - documented in political psychology literature.

Kunda (1990): people accept confirming evidence without scrutiny while applying heightened scrutiny to disconfirming evidence. Motivated reasoning is not simple irrationality; people sincerely believe they are reasoning correctly. The motivation is typically identity-protective or outcome-motivated.	4
Backfire Effect backfire_effect Aliases belief perseverance, correction backfire, worldview backfire Distinguishing Features Directly relevant to the DIM's correction reach asymmetry logic: even when corrections reach the right audience, belief perseverance may prevent them from working. This is why reach-weighting matters - the question is not just whether a correction exists but whether it can change minds when it arrives. Distinct from motivated reasoning (which is the cognitive mechanism) - backfire effect is the paradoxical outcome.

Source: Political psychology literature on identity-protective cognition Issue: immigration	concept	-	both	established	belief perseverance, correction backfire, worldview backfire	The phenomenon in which corrections or disconfirming evidence cause beliefs to strengthen rather than weaken - particularly in high-identity, politically charged contexts. Nyhan & Reifler (2010) identified three subtypes: familiarity backfire (corrections make the myth more memorable), overkill backfire (too many arguments triggers reactance), and worldview backfire (evidence threatening to core identity produces defensive strengthening). Important caveat: subsequent replications (Wood & Porter, 2019) suggest the effect is less universal than originally claimed; it is strongest in high-identity contexts.	4
Spiral of Silence spiral_of_silence Aliases opinion silencing spiral, vocal minority effect Distinguishing Features The mechanism is perceived distribution of opinion, not actual distribution. Connected to brigading, astroturfing, and false amplification - all can artificially trigger the spiral by manufacturing the appearance of overwhelming consensus. Distinct from echo chambers: the spiral of silence operates across all contexts; echo chambers are specific enclosed environments. Distinguishes From pluralistic_ignorancefalse_amplificationmajority_illusion Common Co-occurrences pluralistic_ignorancemajority_illusionfalse_amplificationastroturfing Crossover Debate Terminology None Examples People who privately supported Remain but did not express this in Leave-majority social contexts, reinforcing the impression of universal Leave sentiment.

Source: Intersection of brigading and spiral of silence research Issue: media discourse	concept	-	both	established	opinion silencing spiral, vocal minority effect	A self-reinforcing dynamic in which an individual's perception of the distribution of public opinion influences their willingness to express their own view - when people believe they hold a minority position they tend to remain silent, which makes the perceived majority view appear even more dominant, recruiting further silence. Noelle-Neumann (1974). On social media, algorithmic amplification of vocal minorities can create false impressions of majority consensus, triggering the spiral even when the vocal position is not actually the majority.	4
Pluralistic Ignorance pluralistic_ignorance Aliases collective illusion, false consensus effect (inverse), normative misperception Distinguishing Features Distinct from majority illusion (which is network-structural) and spiral of silence (which is the dynamic process): pluralistic ignorance is the stable state of collective misperception. The high-reach intervention implications for DIM: if a small group with high reach dominates the visible discourse, the Epistemic Reach Index may capture a distorted picture of actual opinion distribution. Distinguishes From majority_illusionspiral_of_silencefalse_amplification Common Co-occurrences majority_illusionspiral_of_silencefalse_amplificationecho_bait Crossover Debate Terminology None Examples Party membership privately unconvinced by a policy position but each assuming the others are convinced - conforming to an apparent consensus nobody holds.

Allport (1924); extended in Noelle-Neumann's spiral of silence framework. On social media, when a loud group dominates visible discourse it can appear more representative than it is, producing pluralistic ignorance at scale.	4
Hashtag Hijacking hashtag_hijacking Aliases tag hijacking, hashtag raid, discourse redirect Distinguishing Features Distinct from hashtag drift by speed and intentionality: drift is gradual adoption by out-groups; hijacking is rapid, coordinated flooding. The goal is to overwhelm the original discourse signal with competing content, making the hashtag unusable for its intended community or changing the associations that platforms and algorithms form with it.

Hijacking is typically more rapid and deliberately targeted. Formalised in legal studies, health communication, and far-right platform studies.	4
Networked Harassment networked_harassment Aliases dogpiling, pile-on, morally motivated networked harassment, calling-out (coercive) Distinguishing Features Participants often genuinely believe they are engaged in legitimate criticism or accountability rather than harassment. The aggregate effect is suppression regardless of individual intent. Distinct from brigading (which typically has political/ideological motivation without moral justification framing) and from organised trolling (which lacks the moral framing). Distinguishes From brigadingratio_panicoutrage_cycle Common Co-occurrences brigadingoutrage_cyclespiral_of_silenceratio_panic Crossover Debate Terminology None Examples Academic or journalist posts a view on trans issues; thousands of replies within hours, many framing the harassment as 'holding them accountable' - the aggregate effect is suppression of the speaker and chilling effect on others.

Formalised by Marwick (2021) as 'morally motivated networked harassment as normative reinforcement'. Distinct from brigading by the moral justification typically offered by participants.	4
Search Engine Manipulation Effect seme Aliases SEME, search ranking bias, search manipulation Distinguishing Features The mechanism is the user's assumption of neutrality: unlike advertising (which is labelled) or advocacy (which is attributed), search rankings appear to reflect objective relevance. This makes SEME harder to detect and resist than explicit persuasion. Connects to data_void: when data voids are filled with partisan content, SEME becomes the delivery mechanism for that content's influence.

Formalised by Epstein & Robertson in a PNAS 2015 paper showing that biased search rankings could shift undecided voters' preferences by 20% or more, with no awareness of the influence.	4
Social Bot social_bot Aliases political bot, Twitter bot, automated account, bot account Distinguishing Features Distinct from synthetic personas (which are high-quality AI-generated human-appearing identities) by typically being lower quality and higher volume. A social bot may have a minimal profile and scripted behaviour; a synthetic persona aims for sustained human-quality interaction. Both are forms of astroturfing but at different quality levels.

Formalised in computational social science by Ferrara et al. (2016). Political bots are the political specialisation - used in elections, referendums, and political campaigns.	4
Agenda Setting agenda_setting Aliases media agenda setting, issue salience, media priming (related) Distinguishing Features Closely related to but distinct from the Overton window: agenda setting determines which issues are salient; the Overton window determines which positions on those issues are considered acceptable. Media agenda setting is one of the primary mechanisms through which Overton windows shift. Hallin's spheres describes how journalists police what enters the agenda. Together these three concepts form the conceptual backbone of the DIM's Overton map.

McCombs & Shaw (1972) foundational empirical study. On social media, agenda setting is no longer controlled exclusively by mass media - algorithmic amplification, viral content, and coordinated campaigns can set agendas faster and with less transparency than traditional journalism.	4
False Balance false_balance Aliases both-sidesing, journalistic false balance, false equivalence (editorial) Distinguishing Features Distinct from legitimate balance (presenting genuinely contested empirical or normative debates fairly) by the misrepresentation of the evidential landscape. Distinct from bothsiderism: false balance is a structural editorial practice; bothsiderism is the individual speaker's fallacy of treating disagreement as requiring a midpoint. Both produce the same epistemic harm - false impression of equivalence - via different mechanisms.

Boykoff & Boykoff (2004) documented its systematic effect on climate change coverage. The institutional complement to bothsiderism: false balance is an editorial practice, bothsiderism is a speaker move.	4
Engagement Bait engagement_bait Aliases react baiting, share baiting, tag baiting, vote baiting, comment baiting Distinguishing Features The tell is the explicit call to engagement as primary purpose rather than as response to substantive content: 'tag someone who...', 'share if you agree', 'comment YES or NO'. The content is engineered backward from the engagement action. Platform integrity policies specifically suppress engagement bait because it degrades feed quality. Distinguishes From echo_baitrage_baitoutrage_cycle Common Co-occurrences echo_baitrage_baitviral_authorityoutrage_cycle Crossover Debate Terminology None Examples 'Comment YES if you think the NHS should be protected from privatisation' - the binary engagement action produces a visible signal that can be cited as 'public opinion'.

Operationalised and named in Facebook's 2017 platform policy. Broader than echo_bait (which targets in-group amplification specifically) - engagement bait targets any engagement metric regardless of audience.	4
Hallin's Spheres hallins_spheres Aliases spheres of discourse, journalistic legitimacy spheres, media objectivity zones Distinguishing Features Descriptive rather than prescriptive - Hallin describes how journalists actually treat ideas, not how they should. Closely related to but distinct from the Overton window: the Overton window describes what the public will tolerate; Hallin's spheres describe how journalists police legitimacy. Together with agenda_setting, they form the conceptual framework for the DIM's Overton map. Key insight for DIM: moving an idea from the sphere of deviance to legitimate controversy is a measurable discursive event visible in corpus data. Distinguishes From overton_windowagenda_settingframing Common Co-occurrences overton_windowagenda_settingframingfalse_balance Crossover Debate Terminology None Examples Wealth redistribution: moved from sphere of deviance (1980s–2010s UK) toward sphere of legitimate controversy (post-2015) - measurable in the quantity of mainstream media debate.

Non Sequitur non_sequitur Aliases it does not follow, formal fallacy (general) Distinguishing Features Formal fallacies are errors in argument structure; informal fallacies are errors in content, relevance, or context.

Affirming the Consequent affirming_the_consequent Aliases converse error, fallacy of the converse Distinguishing Features Valid form is modus ponens (if A then B; A; therefore B).

The truth of the consequent (B) does not establish the truth of the antecedent (A) - there may be other explanations for B.	3
Denying the Antecedent denying_the_antecedent Aliases inverse error, fallacy of the inverse Distinguishing Features Valid form is modus tollens (if A then B; not B; therefore not A). The fallacy wrongly runs the inference from not-A to not-B. Distinguishes From affirming_the_consequentnon_sequitur Common Co-occurrences false_dilemmanon_sequitur Crossover Debate Terminology None Examples 'If we cut taxes, growth increases. We haven't cut taxes. Therefore growth won't increase.' Growth might increase for other reasons. Source: UK economic debate Issue: fiscal policy 'If he were innocent he would have cooperated.

The falsity of the antecedent (A) does not establish the falsity of the consequent (B) - B might be true for other reasons.	2
Affirming a Disjunct affirming_a_disjunct Aliases fallacy of the alternative syllogism, exclusive disjunction error Distinguishing Features Most natural language 'or' is inclusive. Treating it as exclusive generates false exclusions. Common in false dilemma situations where more than two things can be simultaneously true. Distinguishes From false_dilemmadenying_the_antecedent Common Co-occurrences false_dilemmanon_sequitur Crossover Debate Terminology None Examples 'You're either with us or against us. You're with us. So you're not against us in any way.' One can support a cause while disagreeing on tactics.

Both are simultaneously addressable. Source: UK political debate Issue: immigration	formal_fallacy	formal_structure	classical	established	fallacy of the alternative syllogism, exclusive disjunction error	Invalid argument form (under inclusive or): A or B; A is true; therefore B is false. In standard logic, 'or' is inclusive - both A and B can be true simultaneously. Only under exclusive 'or' does A's truth rule out B.	2
Appeal to Probability appeal_to_probability Aliases probabilistic fallacy, argument from likelihood Distinguishing Features Distinct from legitimate probabilistic reasoning, which acknowledges uncertainty. The fallacy collapses possibility or likelihood into certainty. Common in worst-case scenario arguments. Distinguishes From slippery_slopeappeal_to_feargamblers_fallacy Common Co-occurrences slippery_slopeappeal_to_fearnon_sequitur Crossover Debate Terminology None Examples 'Some immigrants will commit crimes, therefore immigration causes crime.' The possibility that some will does not establish crime as a general consequence. Source: UK immigration discourse Issue: immigration 'AI could be used maliciously, therefore it will be - and therefore we face an existential risk.' Possibility treated as certainty without probability assessment. Source: UK AI regulation debate Issue: ai_regulation	formal_fallacy	formal_structure	classical	established	probabilistic fallacy, argument from likelihood	Treating a probable outcome as certain, or a possible outcome as probable, without accounting for actual probabilities. Assumes that because something could happen or is likely, it will happen or has happened.	2
Argument from Fallacy argument_from_fallacy Aliases fallacy fallacy, argumentum ad logicam Distinguishing Features An argument's invalidity establishes only that the conclusion hasn't been proven by this argument - not that the conclusion is false. Commonly deployed to dismiss a position by identifying any flaw in any argument for it, however minor. Distinguishes From ad_hominemgenetic_fallacynon_sequitur Common Co-occurrences ad_hominemgenetic_fallacystrawman Crossover Debate Terminology None Examples 'Your argument for the wealth tax contained a statistical error, therefore wealth taxes don't work.' The policy's merits are independent of this particular argument's validity. Source: UK wealth tax debate Issue: wealth tax 'The NHS funding argument you made was based on cherry-picked data, so the NHS isn't underfunded.' The conclusion may still be correct via other evidence. Source: UK health policy debate Issue: nhs_funding	formal_fallacy	formal_structure	classical	established	fallacy fallacy, argumentum ad logicam	Assuming that a conclusion must be false because the argument presented for it is fallacious. A bad argument for a true conclusion does not make the conclusion false - the conclusion may be true for other, unstated reasons.	2
Base Rate Fallacy base_rate_fallacy Aliases base rate neglect, prior probability neglect, prosecutor's fallacy Distinguishing Features Distinct from conjunction fallacy (which involves compound probabilities). Often causes dramatic overestimation of risk when the base rate of the thing feared is very low. Distinguishes From conjunction_fallacyhasty_generalisationecological_fallacy Common Co-occurrences hasty_generalisationappeal_to_fearcherry_picking Crossover Debate Terminology None Examples 'A terrorist was found to be an immigrant. A test for terrorism correctly identifies terrorists 90% of the time. If your immigration status matches the profile, you are likely a terrorist.' Ignores that terrorists are extremely rare among immigrants.

Source: Vaccine discourse, documented Issue: public health	formal_fallacy	formal_structure	classical	established	base rate neglect, prior probability neglect, prosecutor's fallacy	Ignoring prior probabilities (base rates) when making probability judgements - overweighting specific evidence while failing to account for how common or rare the thing being estimated actually is. Tversky & Kahneman documented this extensively. The prosecutor's fallacy (misusing conditional probability in criminal evidence) is a high-stakes application.	3
Conjunction Fallacy conjunction_fallacy Aliases Linda problem, compound probability error Distinguishing Features Exploited deliberately in political messaging by adding specific, plausible-sounding details to make a scenario feel more probable. The more vivid and representative the story, the more likely people are to commit the fallacy. Distinguishes From base_rate_fallacyappeal_to_probability Common Co-occurrences appeal_to_fearnarrative_launderingframing Crossover Debate Terminology None Examples 'An immigrant who claims asylum, then commits a crime, then receives benefits' - the specificity of the compound scenario makes it feel more likely than 'an immigrant causes harm', though it is mathematically less probable.

Source: UK electoral politics, generic Issue: electoral politics	formal_fallacy	formal_structure	classical	established	Linda problem, compound probability error	The error of judging a conjunction of two conditions as more probable than either condition alone. Tversky & Kahneman (1983): people routinely rate a specific detailed scenario as more probable than a less specific one, despite the mathematical impossibility - a conjunction can never be more probable than either of its conjuncts.	2
Masked Man Fallacy masked_man_fallacy Aliases intensional fallacy, epistemic fallacy, Leibniz's law misapplication Distinguishing Features Classic example: 'I know who my father is. My father is the masked man. Therefore I know who the masked man is.' The second premise doesn't transfer knowledge, because knowledge is intensional. Relevant to identity claims and attributions in political discourse. Distinguishes From equivocationnon_sequitur Common Co-occurrences equivocationsemantic_dodge Crossover Debate Terminology None Examples 'You support free speech. Free speech includes the right to spread misinformation. Therefore you support spreading misinformation.' The inference doesn't follow in the intensional context of what 'support' means.

Modal Fallacy modal_fallacy Aliases necessity/possibility confusion, modal scope fallacy Distinguishing Features Technical but appears in policy debates around risk and possibility. 'It is possible that AI will be dangerous' does not mean 'AI will necessarily be dangerous in any given deployment'. Distinguishes From appeal_to_probabilitynon_sequitur Common Co-occurrences appeal_to_probabilityslippery_slope Crossover Debate Terminology None Examples 'It is necessarily true that if someone commits a crime they are a criminal. This person committed a crime. Therefore they are necessarily a criminal.' The necessity applies to the conditional, not the conclusion.

Source: UK AI regulation discourse Issue: ai_regulation	formal_fallacy	formal_structure	classical	established	necessity/possibility confusion, modal scope fallacy	Confusing different modal operators - necessity, possibility, actuality - or misapplying the scope of modal claims. Most common form: treating 'it is possible that X' as 'X is possible in this specific case', or treating 'necessarily, if A then B' as 'if A, then necessarily B'.	2
Existential Fallacy existential_fallacy Aliases existential instantiation error Distinguishing Features Technical formal fallacy. Arises in policy debates when general rules are applied to populations that may not exist as assumed. Distinguishes From sweeping_generalisationnon_sequitur Common Co-occurrences sweeping_generalisationhasty_generalisation Crossover Debate Terminology None Examples 'All benefit fraudsters are criminals. Some criminals should be imprisoned. Therefore some benefit fraudsters should be imprisoned.' Doesn't follow without establishing that benefit fraudsters who are criminals are the criminal type that warrants imprisonment. Source: UK welfare policy debate Issue: welfare policy 'All AI systems that deceive humans are dangerous. Some dangerous systems should be regulated. Therefore some AI systems that deceive should be regulated.' The 'some' conclusion requires establishing the first class is non-empty in the relevant way.

Classical logic requires existential import: 'all A are B' does not imply 'some A are B' if the class A is empty.	2
Fallacy of Undistributed Middle fallacy_of_undistributed_middle Aliases undistributed middle term Distinguishing Features Classic invalid form: 'All communists support the NHS. This politician supports the NHS. Therefore this politician is a communist.' NHS supporters is the undistributed middle. Distinguishes From non_sequiturfallacy_of_four_terms Common Co-occurrences hasty_generalisationaffirming_the_consequent Crossover Debate Terminology None Examples 'All socialists want to redistribute wealth.

Immigration opponents is the undistributed middle. Source: UK immigration debate framing Issue: immigration	formal_fallacy	formal_structure	classical	established	undistributed middle term	A syllogistic error where the middle term (the term appearing in both premises but not the conclusion) is not distributed - does not refer to all members of its class - in either premise. Without at least one premise in which the middle term is distributed, the inference is invalid.	2
Fallacy of Four Terms fallacy_of_four_terms Aliases quaternio terminorum, equivocation in syllogism Distinguishing Features Closely related to equivocation but specifically in syllogistic form. 'Nothing is better than eternal happiness. A sandwich is better than nothing. Therefore a sandwich is better than eternal happiness.' 'Nothing' means different things in each premise. Distinguishes From equivocationfallacy_of_undistributed_middle Common Co-occurrences equivocationsemantic_dodge Crossover Debate Terminology None Examples 'The rich should pay more tax because they have more. I have more experience than my employer. Therefore I should pay more tax.' 'More' shifts meaning across premises.

Source: UK equality policy debate Issue: social policy	formal_fallacy	formal_structure	classical	established	quaternio terminorum, equivocation in syllogism	A syllogism that superficially appears to have three terms but actually has four - typically because a word is used with two different meanings (equivocation) across the premises, making the argument structurally invalid despite appearing valid.	2
Illicit Major / Illicit Minor illicit_major_minor Aliases illicit process, illicit major, illicit minor Distinguishing Features Technical formal fallacy. The conclusion claims more than the premises establish - a specific form of the broader principle that conclusions cannot exceed their premises. Distinguishes From fallacy_of_undistributed_middlehasty_generalisation Common Co-occurrences hasty_generalisationsweeping_generalisation Crossover Debate Terminology None Examples Illicit major: 'All terrorists are violent.

Ad Hominem (Tu Quoque) ad_hominem_tu_quoque Aliases you too fallacy, appeal to hypocrisy (argument form), two wrongs make a right Distinguishing Features The critic's behaviour may be genuinely hypocritical, but that does not make their criticism wrong. The criticism must be addressed on its merits independently of who is making it. Distinct from whataboutism: tu quoque involves the same critic; whataboutism typically introduces a different party. Distinguishes From whataboutismad_hominemappeal_to_hypocrisy Common Co-occurrences whataboutismad_hominemred_herring Crossover Debate Terminology None Examples 'You're criticising my expenses claims? You claimed mileage for journeys that didn't happen.' Even if true, this doesn't address whether the original expenses claim was improper. Source: UK parliamentary expenses scandal discourse Issue: electoral politics 'You complain about corporate tax avoidance but your pension is invested in these companies.' The investment may be hypocritical but doesn't address whether the tax avoidance is wrong. Source: UK wealth tax discourse Issue: wealth tax 'You're attacking our immigration policy but your party had the same targets in 2010.' Historical symmetry does not address whether the current policy is appropriate. Source: UK immigration debate Issue: immigration	non-engagement	source_attacks	classical	established	you too fallacy, appeal to hypocrisy (argument form), two wrongs make a right	Dismissing or deflecting a criticism by pointing out that the critic engages in the same behaviour - 'you too'. The move attempts to neutralise a charge by establishing symmetry, without addressing whether the charge is valid. Distinct from whataboutism (which deflects by introducing a third party's behaviour) and from legitimate hypocrisy identification (which is relevant when the arguer's consistency is itself the issue).	3
Ad Hominem (Circumstantial) ad_hominem_circumstantial Aliases circumstantial ad hominem, conflict of interest dismissal, you would say that Distinguishing Features Legitimate use: noting a conflict of interest as context for evaluating evidence. Fallacious use: treating the conflict of interest as sufficient refutation of the argument. The former is epistemically relevant; the latter is not. Closely related to genetic fallacy but more specifically about the speaker's stakes. Distinguishes From genetic_fallacyad_hominempoisoning_the_well Common Co-occurrences genetic_fallacypoisoning_the_wellad_hominem Crossover Debate Terminology None Examples 'Gary Stevenson argues for a wealth tax - but he grew up poor and resents the wealthy.

Source: UK health policy debate Issue: nhs_funding 'The think tank funded by fossil fuel companies says carbon taxes harm growth - well they would say that.' Their funding is relevant context, but the economic claim requires engagement on its merits. Source: UK climate policy debate Issue: ai_regulation	non-engagement	source_attacks	classical	established	circumstantial ad hominem, conflict of interest dismissal, you would say that	Dismissing an argument by pointing to the arguer's circumstances, interests, or position - implying their conclusion is biased rather than engaging with its content. 'You would say that, wouldn't you?' The circumstances may create a genuine conflict of interest worth noting, but they do not establish that the argument is wrong.	3
Appeal to False Authority appeal_to_false_authority Aliases appeal to dubious authority, irrelevant authority, celebrity endorsement fallacy Distinguishing Features A physicist's opinion on climate science is relevant; their opinion on immigration policy is not. A celebrity's endorsement of a political candidate is not expert testimony. Proliferates in platform environments where follower counts substitute for expertise (see viral_authority). Distinguishes From appeal_to_authorityviral_authoritygenetic_fallacy Common Co-occurrences appeal_to_authorityviral_authorityappeal_to_the_masses Crossover Debate Terminology None Examples Elon Musk tweeting economic policy positions as authoritative despite no economics training - and those positions being amplified by his follower count rather than their evidential merit.

Distinct from appeal_to_authority (which correctly names the misuse of genuine credentials) by focusing on the absence or irrelevance of the credentials being invoked.	4
Appeal to the Masses appeal_to_the_masses Aliases ad populum, appeal to popularity, argumentum ad populum, bandwagon fallacy Distinguishing Features Distinct from legitimate democratic argument: in democratic contexts, majority preference is a valid basis for some decisions (policy choices) but not for truth claims. The fallacy conflates popular belief with factual correctness. Directly related to viral_authority and majority_illusion. Distinguishes From viral_authoritymajority_illusionappeal_to_false_authority Common Co-occurrences viral_authoritymajority_illusionfalse_amplification Crossover Debate Terminology None Examples 'Millions of people believe immigration is the biggest problem facing Britain, so it must be.'

Appeal to supposed common knowledge as substitute for economic evidence. Source: UK wealth tax debate Issue: wealth tax 'The great majority of British people support leaving the single market - so it must be the right decision.' Democratic mandate for a policy does not establish its empirical consequences. Source: UK Brexit discourse Issue: electoral politics	manipulation	psychological_rhetoric	both	established	ad populum, appeal to popularity, argumentum ad populum, bandwagon fallacy	Arguing that a claim is true or a course of action is correct because many people believe it or do it. Majority opinion is not evidence of truth - historically, majorities have held false beliefs. In platform contexts, dramatically amplified when engagement metrics (likes, shares, trending status) serve as visible proxies for consensus.	4
Appeal to Tradition appeal_to_tradition Aliases ad antiquitatem, appeal to antiquity, is-ought from tradition, traditionalist fallacy Distinguishing Features Distinct from legitimate conservative arguments: arguing that change should be approached cautiously, or that existing institutions embody accumulated wisdom, is a substantive position. The fallacy is treating tradition alone as sufficient justification. Heavily used in political rhetoric to defend existing arrangements without engaging arguments for change. Distinguishes From appeal_to_noveltyargument_from_priorbegging_the_question Common Co-occurrences appeal_to_noveltyargument_from_priorspecial_pleading Crossover Debate Terminology None Examples 'We've always had a first-past-the-post electoral system and it's served us well.'

Appeal to supposed historical tradition as argument against current immigration policy critique. Source: UK immigration discourse Issue: immigration 'The NHS has always been free at the point of use - we shouldn't change that.' While popular, tradition alone isn't sufficient justification; the argument needs to engage with reform proposals. Source: UK health policy debate Issue: nhs_funding	manipulation	psychological_rhetoric	classical	established	ad antiquitatem, appeal to antiquity, is-ought from tradition, traditionalist fallacy	Arguing that something is correct, good, or should be continued because it is traditional or has been done for a long time. Longevity does not establish correctness - many long-standing practices have been unjust or harmful.	4
Appeal to Novelty appeal_to_novelty Aliases ad novitatem, appeal to the new, novelty bias Distinguishing Features Heavily used in technology and policy marketing. Legitimate in some narrow contexts - new scientific evidence should update prior beliefs - but the fallacy is treating novelty as inherently positive rather than as something requiring evaluation. Distinguishes From appeal_to_traditionappeal_to_false_authority Common Co-occurrences appeal_to_traditionviral_authorityappeal_to_the_masses Crossover Debate Terminology None Examples 'AI-based hiring is better because it's the future of HR.' Novelty of method does not establish superior outcomes for hiring quality or fairness.

Source: UK health policy debate Issue: nhs_funding	manipulation	psychological_rhetoric	both	established	ad novitatem, appeal to the new, novelty bias	Arguing that something is better, more correct, or should be preferred because it is new or modern. Newness does not establish superiority - new ideas can be wrong, new technologies can cause harm. The inverse of appeal to tradition.	3
Appeal to Nature appeal_to_nature Aliases naturalistic fallacy (informal), natural is good fallacy Distinguishing Features Distinct from the naturalistic fallacy (Hume's is-ought gap) which is a broader philosophical claim. This is the specific informal fallacy of treating 'natural' as synonymous with 'good'. Distinct from legitimate environmental arguments that track actual harms and benefits. Distinguishes From appeal_to_traditionbegging_the_question Common Co-occurrences appeal_to_traditionappeal_to_emotion Crossover Debate Terminology None Examples 'Organic food is better for you because it's natural.' Natural doesn't entail healthier - arsenic is natural. Source: UK food and health discourse Issue: public health 'Same-sex relationships are unnatural, therefore wrong.'

Source: UK social policy discourse Issue: social policy 'Natural immunity is better than vaccine-induced immunity because it's how our bodies evolved to fight disease.' The evolutionary origin of immunity doesn't establish relative effectiveness. Source: UK vaccine discourse Issue: public health	manipulation	psychological_rhetoric	classical	established	naturalistic fallacy (informal), natural is good fallacy	Arguing that something is good, correct, or beneficial because it is natural, or bad because it is unnatural. The natural/unnatural distinction does not track good/bad - many natural things are harmful, many unnatural things are beneficial. Widely used in health, food, environmental, and social policy discourse.	4
Appeal to Ignorance appeal_to_ignorance Aliases ad ignorantiam, argument from ignorance, burden of proof reversal Distinguishing Features Legitimate burden of proof allocation: in many contexts, the burden falls on the positive claim. The fallacy is treating absence of disproof as positive evidence. Very common in conspiracy theory argument structures where the absence of exposed conspiracies is cited as evidence of their success. Distinguishes From argument_from_silencebegging_the_questionbase_rate_fallacy Common Co-occurrences argument_from_silencejaqingconspiracy_rhetoric Crossover Debate Terminology None Examples 'Nobody has proven that 5G causes health problems, but nobody has proven it doesn't either - so we should be cautious.'

Absence of harm evidence is not positive safety evidence. Source: UK wellness industry discourse Issue: public health	manipulation	psychological_rhetoric	classical	established	ad ignorantiam, argument from ignorance, burden of proof reversal	Claiming that something is true because it has not been proven false, or false because it has not been proven true. The absence of evidence is not evidence of absence - and is not evidence of presence either. Reverses the standard burden of proof.	4
Appeal to Force appeal_to_force Aliases ad baculum, argument from threat, coercive argument Distinguishing Features Distinct from legitimate warnings (which inform rather than coerce): 'if you do X, Y will happen' as factual prediction is different from 'agree with me or Y will happen to you'. In platform contexts, brigading and networked harassment often function as ad baculum at scale. Distinguishes From appeal_to_fearbrigadingnetworked_harassment Common Co-occurrences appeal_to_fearbrigadingpoisoning_the_well Crossover Debate Terminology None Examples 'If you keep criticising Amazon's practices, you'll find your account suspended.' The threat doesn't address whether the criticism is accurate.

Threat of social consequence rather than engagement with the policy argument. Source: UK immigration discourse Issue: immigration 'If you publish that analysis of our tax avoidance, we'll withdraw our advertising from your publication.' Economic threat as argument. Source: UK media economics, documented pattern Issue: media discourse UK government briefing journalists that critical reporting will result in loss of access - an implicit ad baculum. Source: UK press-government relations, documented Issue: media discourse	manipulation	psychological_rhetoric	classical	established	ad baculum, argument from threat, coercive argument	Using the threat of negative consequences - physical, economic, political, or social - to compel agreement rather than presenting rational argument. The threat may be explicit or implicit. The conclusion may be true or false regardless of the threat; the threat is irrelevant to the argument's merits.	4
Appeal to Consequences appeal_to_consequences Aliases ad consequentiam, argument from consequences, wishful thinking (epistemic) Distinguishing Features Distinct from legitimate consequentialist policy argument: arguing that a policy should be adopted because of its good consequences is valid. The fallacy is arguing that an empirical claim must be true or false because of what would follow if it were. Commonly used to avoid uncomfortable factual conclusions. Distinguishes From appeal_to_fearwishful_thinkingbackfire_effect Common Co-occurrences appeal_to_fearmotivated_reasoningbackfire_effect Crossover Debate Terminology None Examples 'If we accept that inequality is structural, people will lose hope and stop trying - therefore structural inequality doesn't exist.'

Epistemic consequence doesn't determine empirical truth. Source: UK immigration policy debate Issue: immigration 'Telling people their votes don't matter will suppress turnout - therefore we should insist all votes count equally.' Even if the consequence is desirable, that doesn't make the claim true. Source: UK electoral reform debate Issue: electoral politics 'If we admit AI poses risks, it will slow down innovation - so we should emphasise benefits.' Desirable consequences of belief do not establish its truth. Source: UK AI regulation debate Issue: ai_regulation	manipulation	psychological_rhetoric	classical	established	ad consequentiam, argument from consequences, wishful thinking (epistemic)	Arguing that a claim must be true or false because of the desirability or undesirability of its consequences - if the consequences of believing X are bad, X must be false; if the consequences of believing X are good, X must be true. The truth of a claim is independent of the desirability of its being true.	4
Argument from Silence argument_from_silence Aliases ex silentio, argument from absence, silence as evidence Distinguishing Features Sometimes legitimate: if we would expect a denial to have been made and none occurred, silence may be evidence. But the fallacy is treating silence as automatically significant. Related to appeal_to_ignorance but more specifically about the absence of statements rather than the absence of proof. Distinguishes From appeal_to_ignoranceepistemic_cowardicestrategic_silence Common Co-occurrences appeal_to_ignorancejaqingconspiracy_rhetoric Crossover Debate Terminology None Examples 'The government hasn't denied that meetings took place - therefore meetings must have taken place.'

Many valid reasons not to respond to every critic. Source: UK economic discourse Issue: wealth tax 'Ancient sources don't mention this event - therefore it didn't happen.' Absence from the historical record has limited evidential value for events that wouldn't necessarily be recorded. Source: Historical and political discourse Issue: media discourse 'Amazon hasn't corrected this interpretation of their policy - so it must be correct.' Silence on a specific interpretation is not endorsement. Source: Platform seller discourse Issue: platform economics	non-engagement	evidence_quality	classical	established	ex silentio, argument from absence, silence as evidence	Treating the absence of a statement, record, or response as evidence for a particular conclusion - either that something didn't happen (because it wasn't recorded) or that something did happen (because it wasn't denied). The epistemic weight of silence depends entirely on whether we would expect a record or response if the thing in question were true or false.	4
Hasty Generalisation hasty_generalisation Aliases converse accident, overgeneralisation, anecdotal evidence fallacy, insufficient sample Distinguishing Features The diagnostic question is whether the sample is large enough and representative enough to support the conclusion. Anecdotal evidence ('I know someone who...') is the most extreme form. Distinct from cherry picking (which involves deliberately selecting from a larger pool); hasty generalisation may involve genuine ignorance of the broader picture. Distinguishes From cherry_pickingsampling_biasecological_fallacy Common Co-occurrences cherry_pickingsampling_biasappeal_to_the_masses Crossover Debate Terminology None Examples 'I met an asylum seeker who was working cash-in-hand.

The generalisation may be stated confidently despite the evidence base being far too thin to support it. One of the most prevalent fallacies in political discourse - particularly common in immigration and crime debates where individual cases are used to generate population-level conclusions.	4
Sweeping Generalisation sweeping_generalisation Aliases accident fallacy, dicto simpliciter, ignoring the exception Distinguishing Features Distinct from hasty generalisation by direction: sweeping generalises downward (general rule to specific case). The rule may be entirely valid as a general principle; the error is ignoring the specific exception. Common in policy debates where general rules encounter edge cases. Distinguishes From hasty_generalisationspecial_pleadingfalse_dilemma Common Co-occurrences hasty_generalisationspecial_pleadingfalse_dilemma Crossover Debate Terminology None Examples 'People should work for their income. Therefore disabled people who can't work should receive no state support.' The general principle doesn't apply to the specific case without qualification. Source: UK welfare policy debate Issue: welfare policy 'Free speech means you can say anything. Therefore you can say anything in a courtroom.' General principle doesn't apply to specific legal contexts. Source: Free speech policy debate Issue: media discourse 'The market should determine prices. Therefore drug companies should set the price of insulin.' Market logic applied without accommodation of market failure in healthcare. Source: UK and US healthcare debate Issue: nhs_funding	non-engagement	evidence_quality	classical	established	accident fallacy, dicto simpliciter, ignoring the exception	Applying a general rule to a specific case where the rule does not hold - ignoring relevant exceptions or special circumstances that the rule was not designed to cover. The inverse of hasty generalisation: where hasty generalisation over-extends from specific to general, sweeping generalisation wrongly applies the general to an exceptional specific.	3
Cherry Picking cherry_picking Aliases suppressed evidence, selection bias (argument), incomplete evidence, one-sided presentation Distinguishing Features Every individual claim may be accurate; the fallacy is in the selection. Distinct from legitimate emphasis (choosing the most relevant evidence) by the deliberate exclusion of evidence that would materially alter the conclusion. The tobacco industry's selective publication of favourable research is the canonical institutional example. Distinguishes From hasty_generalisationfalse_balancemalinformation Common Co-occurrences malinformationframinghasty_generalisationsampling_bias Crossover Debate Terminology None Examples Citing GDP growth figures while omitting wage stagnation, regional inequality, and wealth concentration data - accurate partial picture producing false overall impression of economic health. Source: UK economic debate, documented pattern Issue: wealth tax Immigration reporting that presents crime statistics for a demographic group without the comparison base rate, denominator, or comparative statistics for the native-born population. Source: UK tabloid immigration coverage, documented Issue: immigration Tobacco industry's selective publication of studies showing no link between smoking and cancer while suppressing internal research showing the opposite - the canonical institutional cherry picking case. Source: US tobacco litigation, documented; Proctor's research Issue: public health Presenting only peer-reviewed literature critical of the NHS while ignoring literature supporting increased investment - cherry picking within academic literature. Source: UK health policy debate Issue: nhs_funding	non-engagement	evidence_quality	both	established	suppressed evidence, selection bias (argument), incomplete evidence, one-sided presentation	Selecting only the evidence that supports a conclusion while ignoring, suppressing, or failing to present contrary evidence - producing a misleadingly one-sided picture even when each individual claim is true. Described as suppressed evidence in argumentation theory. Arguably the most common fallacy in political discourse and directly related to malinformation.	4
Ecological Fallacy ecological_fallacy Aliases ecological inference fallacy, group-to-individual inference Distinguishing Features Distinct from hasty generalisation (which draws broad conclusions from few cases) by involving valid aggregate statistics misapplied to individuals. The aggregate pattern may be real; the inference to individuals is still invalid. Distinguishes From hasty_generalisationbase_rate_fallacysampling_bias Common Co-occurrences hasty_generalisationbase_rate_fallacycherry_picking Crossover Debate Terminology None Examples 'Areas with high immigration have higher crime rates - therefore immigrants commit more crime.' Correlation at area level does not establish individual-level causation; confounds include deprivation, policing, and reporting. Source: UK immigration discourse, documented statistical misuse Issue: immigration 'Constituencies that voted Leave have higher economic deprivation - therefore Leave voters are economically deprived.' Individual voters in Leave constituencies include all economic strata. Source: UK Brexit discourse Issue: electoral politics 'Countries with higher wealth taxes have slower growth - therefore individual wealth taxes reduce that country's growth.' Country-level correlation may not establish the causal mechanism claimed. Source: UK wealth tax debate Issue: wealth tax	non-engagement	evidence_quality	classical	established	ecological inference fallacy, group-to-individual inference	Inferring conclusions about individuals based on aggregate statistics about the groups to which they belong. Statistical correlations at the group level do not necessarily hold at the individual level. Formally identified by Robinson (1950) in sociology. Extremely common in political arguments using demographic statistics.	3
Fallacy of Composition fallacy_of_composition Aliases part-to-whole fallacy, composition error Distinguishing Features Distinct from fallacy of division (which goes the other direction). Classic economic example: the paradox of thrift - each household saving is prudent, but all households saving simultaneously reduces aggregate demand, harming the economy. Directly relevant to economic policy debates. Distinguishes From fallacy_of_divisionecological_fallacyhasty_generalisation Common Co-occurrences fallacy_of_divisionsweeping_generalisationfalse_cause Crossover Debate Terminology None Examples 'Each company maximising its own profit is rational. Therefore a system where all companies maximise profit produces the best overall outcomes.' The composition produces market failures, externalities, and collective action problems. Source: UK economic policy debate Issue: wealth tax 'Each voter voting for the candidate they prefer produces the best election outcome.' Individual preference satisfaction can produce collective outcomes (like Condorcet cycles) no individual preferred. Source: Electoral systems debate Issue: electoral politics 'If everyone in the economy saves more, the economy will do better.' Paradox of thrift - individual prudence composed to macroeconomic harm. Source: UK economic debate Issue: fiscal policy	non-engagement	formal_structure	classical	established	part-to-whole fallacy, composition error	Assuming that what is true of each part of a whole is therefore true of the whole. The properties of components do not necessarily compose into the same properties at the aggregate level.	3
Fallacy of Division fallacy_of_division Aliases whole-to-part fallacy, division error Distinguishing Features The inverse of fallacy of composition. Water is wet; hydrogen and oxygen are not wet. Common in arguments about group properties and individual members, and in arguments about national statistics and individual cases. Distinguishes From fallacy_of_compositionecological_fallacysweeping_generalisation Common Co-occurrences fallacy_of_compositionecological_fallacysweeping_generalisation Crossover Debate Terminology None Examples 'The UK economy grew by 2% last year - so most people are 2% better off.' National GDP growth does not distribute equally to individuals. Source: UK economic reporting Issue: wealth tax 'The Conservative Party supports fiscal responsibility - so any Conservative MP claiming expenses is being fiscally responsible.' Party-level attribute doesn't apply to each individual action. Source: UK political discourse Issue: electoral politics 'The NHS is the world's fifth-largest employer - so each NHS worker is part of a highly resourced system.' Scale of employment doesn't entail resources per worker. Source: UK health policy debate Issue: nhs_funding	non-engagement	formal_structure	classical	established	whole-to-part fallacy, division error	Assuming that what is true of a whole must be true of each of its parts or members. Aggregate properties do not necessarily disaggregate to individual components.	3
Sampling Bias sampling_bias Aliases biased sample, non-representative sample, selection effect Distinguishing Features Related to hasty generalisation (too few cases) but distinct: sampling bias can involve large samples that are systematically unrepresentative. Online polls, social media sentiment, and reader surveys are common sources of sampling bias in political discourse. Distinguishes From hasty_generalisationcherry_pickingecological_fallacy Common Co-occurrences hasty_generalisationcherry_pickingappeal_to_the_masses Crossover Debate Terminology None Examples Online 'polls' asking website visitors whether they support a politician's position - self-selected audiences that are systematically unrepresentative cited as evidence of public opinion. Source: UK political media, documented pattern Issue: electoral politics Citing a survey of small business owners on wealth tax effects without noting that the survey was conducted by a small business lobby group whose members are disproportionately affected. Source: UK wealth tax debate Issue: wealth tax Survivor bias in economic success stories: profiling successful immigrants while the sample systematically excludes those who faced barriers - producing misleadingly positive picture. Source: UK immigration discourse Issue: immigration Social media sentiment analysis used to claim 'the public' opposes a policy - Twitter/X users are systematically younger, more educated, and more politically engaged than the general population. Source: UK political social media research Issue: media discourse	non-engagement	evidence_quality	both	established	biased sample, non-representative sample, selection effect	Drawing conclusions from a sample that is not representative of the population being studied or described - because of how the sample was selected, who agreed to participate, or what was measured. The conclusions may accurately describe the sample but cannot be validly generalised.	4
Post Hoc Ergo Propter Hoc post_hoc Aliases post hoc, false cause (temporal), after this therefore because of this, correlation-causation (temporal) Distinguishing Features Distinct from cum hoc (which involves simultaneous correlation rather than temporal sequence). Establishing genuine causation requires ruling out confounders, reverse causation, and coincidence. Widely exploited in political attribution - credit is claimed for positive trends and blame deflected from negative ones using post hoc reasoning. Distinguishes From cum_hocfalse_causehasty_generalisation Common Co-occurrences cum_hocfalse_causecherry_picking Crossover Debate Terminology None Examples 'Crime fell after we introduced these policing measures - therefore the policing measures caused the fall in crime.' Crime trends are multi-causal; the temporal sequence alone doesn't establish causation. Source: UK policing policy debate Issue: electoral politics 'The economy grew after we cut taxes - therefore tax cuts caused growth.' Multiple other factors changed simultaneously; the sequence doesn't establish causation. Source: UK fiscal policy debate Issue: wealth tax 'NHS waiting lists grew after the pay dispute - therefore the pay dispute caused the waiting list increase.' The dispute is one factor among many, and waiting lists were already growing. Source: UK health policy debate Issue: nhs_funding 'Immigration increased at the same time wages stagnated - therefore immigration caused wage stagnation.' Temporal overlap doesn't establish causation; both may result from other economic changes. Source: UK immigration discourse Issue: immigration	non-engagement	evidence_quality	classical	established	post hoc, false cause (temporal), after this therefore because of this, correlation-causation (temporal)	Assuming that because one event preceded another, the first caused the second. Temporal sequence is a necessary but not sufficient condition for causation. One of the most common fallacies in political argument - almost any policy claim about cause-and-effect is vulnerable to this error without controlled evidence.	4
Cum Hoc Ergo Propter Hoc cum_hoc Aliases cum hoc, correlation implies causation, false correlation fallacy Distinguishing Features Distinct from post hoc (temporal sequence) by involving simultaneous co-occurrence. Both are instances of false_cause. Particularly prevalent in political arguments using statistical data. Distinguishes From post_hocfalse_causeecological_fallacy Common Co-occurrences post_hocfalse_causecherry_pickinghasty_generalisation Crossover Debate Terminology None Examples 'Countries with lower inequality have better health outcomes - therefore reducing inequality improves health.' The correlation may reflect other factors (social cohesion, public services) or reverse causation. Source: UK inequality debate Issue: wealth tax 'Areas with more police have more crime - therefore policing causes crime.' Reverse causation: police are deployed where crime is already higher. Source: UK policing debate Issue: electoral politics 'Countries with higher vaccination rates had more COVID deaths in some periods - therefore vaccines caused deaths.' Third factors (older populations, variant timing) explain the correlation. Source: Vaccine misinformation discourse, 2021–2022 Issue: public health	non-engagement	evidence_quality	classical	established	cum hoc, correlation implies causation, false correlation fallacy	Assuming causation from simultaneous correlation - because A and B occur together, A must cause B (or B must cause A). Correlation between two variables may result from a third common cause, from coincidence, or from reverse causation. The statistical observation 'A and B are correlated' does not establish which causes which, or whether either causes the other.	3
False Cause false_cause Aliases non causa pro causa, wrong cause, causal fallacy (general) Distinguishing Features Broader than post hoc or cum hoc - covers any incorrect causal identification. In policy debate, false cause is used to attribute political credit or blame; to justify policies by citing causes that don't exist; and to dismiss policies by misidentifying why outcomes occurred. Distinguishes From post_hoccum_hocslippery_slope Common Co-occurrences post_hoccum_hoccherry_pickingframing Crossover Debate Terminology None Examples 'Poverty is caused by poor personal choices.' Misidentifies proximate individual causes while ignoring structural economic causes documented in the literature. Source: UK welfare policy discourse Issue: welfare policy 'Immigration is the cause of the housing crisis.' Attributes a multi-causal structural problem to a single factor, misidentifying both cause and relative magnitude. Source: UK housing and immigration debate Issue: immigration 'The NHS crisis is caused by an ageing population.' Ageing is a contributing factor; it is not sufficient to explain the specific timing and severity of the current crisis without accounting for funding decisions. Source: UK health policy debate Issue: nhs_funding	non-engagement	evidence_quality	classical	established	non causa pro causa, wrong cause, causal fallacy (general)	Incorrectly identifying the cause of an event or phenomenon - either by misattributing causation to correlation, confusing cause and effect, ignoring confounders, or identifying a proximate cause while ignoring a distal cause. The parent category for post hoc and cum hoc.	3
Slippery Slope slippery_slope Aliases thin end of the wedge, camel's nose, domino fallacy, parade of horribles Distinguishing Features Not always fallacious: genuine slippery slopes exist where there is evidence for the causal chain. The fallacy is asserting the chain without evidence. On platforms, algorithmic amplification of extreme content can create genuine slippery slopes in radicalisation pathways - making the fallacious version harder to distinguish from real warnings. Distinguishes From appeal_to_fearfalse_causeappeal_to_consequences Common Co-occurrences appeal_to_fearfalse_dilemmaappeal_to_consequences Crossover Debate Terminology None Examples 'If we allow same-sex marriage, next people will be allowed to marry animals.' No evidence for the causal chain between extending marriage rights to same-sex couples and removing the human requirement. Source: UK same-sex marriage debate, documented Issue: social policy 'If we introduce a wealth tax, the next step is total confiscation of assets and communism.' Each step in the chain requires independent argument and evidence. Source: UK wealth tax debate Issue: wealth tax 'If the government can mandate vaccines, next they'll mandate diet and exercise - it's the end of bodily autonomy.' The causal chain from one public health mandate to all-encompassing state control requires substantial independent argument. Source: UK COVID vaccine discourse Issue: public health 'If we regulate AI content moderation, next the government will control all speech online.' Each step in the regulatory chain requires independent justification. Source: UK AI regulation debate Issue: ai_regulation	non-engagement	evidence_quality	both	established	thin end of the wedge, camel's nose, domino fallacy, parade of horribles	Arguing that a first step will inevitably lead to a series of extreme consequences without providing evidence for each link in the causal chain. The chain from A to Z may be possible, but each intermediate step requires independent justification. A legitimate slippery slope argument provides evidence for each causal link; the fallacy asserts the chain without it.	4
Gambler's Fallacy gamblers_fallacy Aliases Monte Carlo fallacy, hot hand fallacy (inverse), maturity of chances Distinguishing Features The inverse hot-hand fallacy assumes streaks will continue; the gambler's fallacy assumes they must reverse. Both are errors about independent events. In political contexts, often appears as reasoning about electoral cycles or economic patterns. Distinguishes From base_rate_fallacyappeal_to_probabilitypost_hoc Common Co-occurrences base_rate_fallacyappeal_to_probability Crossover Debate Terminology None Examples 'Labour has lost the last three elections - they're due a win soon.' Electoral outcomes are not random independent events, but even if they were, past results wouldn't make future wins more likely. Source: UK electoral discourse Issue: electoral politics 'The economy has been growing for eight years - a recession must be coming.' Business cycles have causes, not statistical regression to a mean. Source: UK economic discourse Issue: fiscal policy	non-engagement	evidence_quality	classical	established	Monte Carlo fallacy, hot hand fallacy (inverse), maturity of chances	Assuming that past independent random events affect the probabilities of future independent events - that after a sequence of one outcome, the opposite outcome becomes more likely. In fact, each independent event's probability is unaffected by previous outcomes. Common in political 'streak' reasoning.	2
Amphiboly amphiboly Aliases grammatical ambiguity, syntactic ambiguity fallacy Distinguishing Features Grammatical structure, not word meaning, is the source of the ambiguity. Less common in political discourse than equivocation but appears in legal and policy language where structural ambiguity can be deliberately exploited. Distinguishes From equivocationfallacy_of_accentsemantic_dodge Common Co-occurrences equivocationsemantic_dodgepersuasive_definition Crossover Debate Terminology None Examples 'We will support nothing but the highest standards.' Does this mean 'we will support only the highest standards' (positive commitment) or 'we won't support anything, just the highest standards' (weak claim)? Source: Generic political language Issue: electoral politics Brexit: 'taking back control of our laws' - grammatically ambiguous between 'control that belongs to us' and 'the act of taking back something we had lost'. Source: UK Brexit discourse Issue: electoral politics	definition	semantic_manipulation	classical	established	grammatical ambiguity, syntactic ambiguity fallacy	Ambiguity arising from the grammatical structure of a sentence rather than from ambiguous words - the structure permits two interpretations, and the fallacy exploits this. Distinct from equivocation, which involves ambiguous words rather than ambiguous grammar.	2
Fallacy of Accent fallacy_of_accent Aliases accent fallacy, misleading emphasis, prosodic ambiguity Distinguishing Features In written form, often manifests as selective quotation that changes emphasis from the original. In broadcast form, relates to how statements are presented. Related to decontextualized_clip in video format. Distinguishes From equivocationcherry_pickingdecontextualized_clip Common Co-occurrences cherry_pickingdecontextualized_clipsemantic_dodge Crossover Debate Terminology None Examples Quoting 'I didn't say he stole the money' in a context that emphasises 'stole' - implying he did take it, just not by stealing - when the original emphasis was on 'he'. Source: Generic example Issue: media discourse Headline: 'EXPERT SAYS WEALTH TAX COULD WORK' - selective capitalisation implying confidence; the body text attributes heavy qualifications. Source: UK media framing, generic Issue: wealth tax	definition	semantic_manipulation	classical	established	accent fallacy, misleading emphasis, prosodic ambiguity	Changing the meaning of a statement by shifting emphasis - either in speech (different stress patterns) or in writing (selective quotation, typography, or context). The words remain identical but the meaning changes with the emphasis.	2
Persuasive Definition persuasive_definition Aliases stipulative definition (manipulative), loaded definition, rhetorical definition Distinguishing Features Related to concept_capture (which involves institutional/cultural capture of a term's meaning) but more specifically about an individual speaker's act of introducing a loaded definition. Distinct from semantic_dodge (which evades definition) by actively proposing one that encodes a position. Distinguishes From concept_capturesemantic_dodgeequivocation Common Co-occurrences concept_capturesemantic_dodgebegging_the_question Crossover Debate Terminology None Examples 'Real economists are those who work within the existing financial system.' Defining 'real' to exclude outsiders - a persuasive definition that encodes the conclusion (Stevenson's analysis applied). Source: UK wealth tax discourse - Rory Stewart / Gary Stevenson context Issue: wealth tax 'Illegal immigrants are those who have no legal right to be here.' Defining the category as those already judged legally in order to beg the normative question. Source: UK immigration discourse Issue: immigration 'True democracy means the will of the people, not the will of Parliament.' Persuasive definition used in Brexit discourse to delegitimise parliamentary scrutiny. Source: UK Brexit discourse Issue: electoral politics	definition	semantic_manipulation	both	established	stipulative definition (manipulative), loaded definition, rhetorical definition	Redefining a term in a way that smuggles in a normative evaluation while presenting the definition as neutral and standard. Coined by Stevenson (1938). The definition appears descriptive but loads a positive or negative charge into the word itself - controlling what the term means is controlling what can be said.	3
Definitional Retreat definitional_retreat Aliases moving the definition, goalpost shifting (definition variant), semantic retreat Distinguishing Features The tell is the mid-argument shift: the term means one thing when making the positive claim and another when a counterexample is introduced. Distinguished from legitimate clarification by the motivated nature of the shift - the new definition is selected to avoid the specific objection. Distinguishes From motte_and_baileyequivocationsemantic_dodge Common Co-occurrences motte_and_baileyno_true_scotsmansemantic_dodge Crossover Debate Terminology None Examples 'Socialism has never worked.' - 'But Scandinavia?' - 'That's not real socialism.' The definition of socialism retreats to exclude successful examples. Source: UK political discourse, generic Issue: electoral politics 'The free market produces the best outcomes.' - 'What about the 2008 financial crisis?' - 'That wasn't a real free market, there was too much regulation.' The definition retreats to exclude the counterexample. Source: UK economic debate Issue: wealth tax 'Immigration is an economic benefit.' - 'But wages in some sectors have been suppressed.' - 'Those aren't the immigrants we're talking about.' Definitional retreat to exclude the problematic cases. Source: UK immigration debate Issue: immigration	definition	semantic_manipulation	classical	established	moving the definition, goalpost shifting (definition variant), semantic retreat	Changing the definition of a key term when challenged - redefining it to avoid a counterexample or objection, then continuing to use the term as if it had always meant the new definition. Related to motte_and_bailey but specifically about definitional instability rather than claim strength.	3
Etymological Fallacy etymological_fallacy Aliases appeal to etymology, word root fallacy, original meaning fallacy Distinguishing Features Etymology is useful context; it does not determine correct contemporary usage. Often used to dismiss established uses of a word by returning to a supposedly purer original meaning. Distinguishes From persuasive_definitionequivocationsemantic_dodge Common Co-occurrences persuasive_definitionappeal_to_tradition Crossover Debate Terminology None Examples 'Literally' comes from the Latin for 'letter' - so it can only mean 'letter for letter'. In fact, 'literally' has acquired a valid emphatic meaning in contemporary usage. Source: Generic prescriptive linguistics argument Issue: media discourse 'Diversity' comes from 'divert' - diverging from the natural order. Used to imply diversity policies are inherently aberrant. Source: UK diversity policy discourse Issue: social policy	definition	semantic_manipulation	classical	established	appeal to etymology, word root fallacy, original meaning fallacy	Assuming that a word's original or etymological meaning represents its correct or true current meaning - that words should be used in accordance with their derivation. In fact, word meanings change over time, and etymological origin does not constrain current usage.	2
Begging the Question begging_the_question Aliases petitio principii, circular argument, question begging, assuming the conclusion Distinguishing Features The circularity may be obvious or concealed behind different vocabulary. Distinct from circular reasoning (which is the broader category) by specifically involving the conclusion as a premise. Very common in political argument where foundational premises go unexamined. Distinguishes From loaded_questioncircular_reasoningpersuasive_definition Common Co-occurrences loaded_questionpersuasive_definitionfalse_dilemma Crossover Debate Terminology None Examples 'The free market is the best system because free markets always produce the best outcomes.' The claim and the premise are the same statement. Source: UK economic debate Issue: wealth tax 'Immigration should be controlled because uncontrolled immigration is bad.' The conclusion (immigration should be controlled) is assumed in the premise (uncontrolled immigration is bad). Source: UK immigration discourse Issue: immigration 'The Bible is true because the Bible says it is the word of God and the word of God is true.' Canonical begging the question example; applies to any circular authority claim. Source: Classic logic textbook example Issue: media discourse 'Wealth redistribution doesn't work because taking money from those who earned it always fails.' The conclusion (it doesn't work) is restated as the premise. Source: UK wealth tax discourse Issue: wealth tax	non-engagement	formal_structure	classical	established	petitio principii, circular argument, question begging, assuming the conclusion	An argument in which the conclusion is assumed in (or is equivalent to) one of the premises - the argument is circular, deriving from itself the thing it claims to establish. Note: 'begging the question' is commonly misused to mean 'raises the question'; the logical fallacy is specifically about circular reasoning.	4
Loaded Question loaded_question Aliases complex question, trick question, presupposition question, have you stopped beating your wife? Distinguishing Features Distinct from jaqing (which makes implications without asking) - loaded questions directly demand response while embedding presuppositions. Distinct from rhetorical questions (which don't expect answers). The power is in making the embedded assumption unavoidable without the respondent noticing. Distinguishes From jaqingbegging_the_questionfalse_dilemma Common Co-occurrences jaqingbegging_the_questionfalse_dilemma Crossover Debate Terminology None Examples Political interviewer: 'When did you decide to abandon the NHS?' Any direct answer accepts the embedded claim that the NHS has been abandoned. Source: UK political interviewing, generic pattern Issue: nhs_funding 'Why does your immigration policy keep failing?' Presupposes the policy is failing without establishing this as a shared starting point. Source: UK parliamentary questioning, generic Issue: immigration 'How long will you keep protecting the wealthy with your tax policy?' Presupposes the policy's purpose and effect. Source: UK wealth tax debate Issue: wealth tax 'When will you apologise for the damage your austerity has caused?' Presupposes both causation and that an apology is owed. Source: UK fiscal policy debate Issue: electoral politics	manipulation	psychological_rhetoric	classical	established	complex question, trick question, presupposition question, have you stopped beating your wife?	A question that contains a contested presupposition - answering yes or no commits the respondent to the embedded assumption without ever having agreed to it. The canonical example: 'Have you stopped beating your wife?' Any direct answer presupposes that wife-beating occurred. Extremely common in political interviewing and parliamentary questions.	4
Foreclosing Interrogation foreclosing_interrogation Aliases interrogative shutdown, discussion-shutting interrogation, performative cross-examination, interrogative overload Distinguishing Features Distinct from loaded_question, which embeds a contested presupposition in a single question, by relying on cumulative overload and foreclosure rather than one trapped answer. Distinct from gish_gallop in that the barrage is framed primarily as questioning rather than assertion, though the two frequently overlap. The hallmark is that the questions are not arranged to be answered but to make answer look impossible or inadequate. Distinguishes From loaded_questiongish_gallopsealioningkafkatrapping Common Co-occurrences loaded_questiongish_gallopad_hominembulverism Crossover Debate Terminology None Examples Wealth-tax clip: 'How do you know they've got a surplus? What are their commitments? How many people are they employing?' The stack of questions is posed faster than it can be answered, creating the impression that the pro-tax position has collapsed under scrutiny. Source: UK wealth tax short-form debate clip Issue: wealth tax Television interviewer fires six rapid policy questions in succession, interrupts every attempted answer, then concludes the guest 'has no plan'. The form of interrogation itself manufactures the failure.

Source: UK health policy debate, generic Issue: nhs_funding Online thread reply dumps a chain of compressed challenges and rhetorical questions, then treats the absence of an immediate point-by-point answer as proof the original claim was indefensible. Source: Online discourse pattern, generic Issue: media discourse	manipulation	semantic_manipulation	both	established	interrogative shutdown, discussion-shutting interrogation, performative cross-examination, interrogative overload	Posing multiple concurrent questions that cannot reasonably be answered in the available format or time, thereby shutting down discussion and manufacturing the appearance that the respondent is unprepared, unserious, or intellectually weak. The effect is not genuine clarification but discursive closure: the asker appears rigorous or intellectually dominant precisely because the exchange has been structured to prevent adequate reply.	4
False Dilemma false_dilemma Aliases false dichotomy, either-or fallacy, black-and-white thinking, bifurcation fallacy Distinguishing Features Distinct from affirming a disjunct (a formal error) by being an informal fallacy about the scope of options presented. The presented options may both be real; the fallacy is the implicit claim that these are the only ones. Platform-native contexts amplify this because binary framing is more shareable and algorithmically favoured. Distinguishes From affirming_a_disjunctslippery_slopebegging_the_question Common Co-occurrences slippery_slopeappeal_to_fearbegging_the_question Crossover Debate Terminology None Examples 'You're either with us or against us.' The binary forecloses critical support, partial agreement, and principled neutrality. Source: US post-9/11 rhetoric; Bush 2001 - widely cited canonical example Issue: geopolitics 'Either we control immigration or we lose national identity.' Presents one specific policy response as the only way to preserve cultural identity, ignoring all intermediate positions. Source: UK immigration discourse Issue: immigration 'Either we introduce a wealth tax or inequality will continue to worsen.' Ignores other redistribution mechanisms, growth policies, and welfare reforms. Source: UK wealth tax debate Issue: wealth tax 'If you support the NHS you must oppose any reform whatsoever.' Forecloses the space between wholesale privatisation and no change. Source: UK health policy debate Issue: nhs_funding	manipulation	psychological_rhetoric	both	established	false dichotomy, either-or fallacy, black-and-white thinking, bifurcation fallacy	Presenting only two options as if they were the only possibilities when in fact more exist - forcing a binary choice on what is actually a spectrum or a multi-option decision. One of the most powerful and prevalent fallacies in political discourse because it forecloses the search for alternative solutions.	4
Argument to Moderation argument_to_moderation Aliases false compromise, middle ground fallacy, golden mean fallacy, argumentum ad temperantiam Distinguishing Features Distinct from legitimate compromise (finding workable policies between disagreeing parties) by making an epistemic claim - that the middle position is more likely to be true. Exploited in political discourse to manufacture equivalence: placing an accurate position and a false position in balance, the 'moderate' conclusion is the average of them, dragging truth toward falsehood. Distinguishes From bothsiderismfalse_balancefalse_dilemma Common Co-occurrences bothsiderismfalse_balancefalse_equivalence Crossover Debate Terminology None Examples Climate debate framed as 'some say catastrophe, some say no problem, the truth is probably somewhere in between.' Scientific evidence is not positioned between two rhetorical poles. Source: Climate communication, documented both-sidesing Issue: ai_regulation 'Extreme left wants total redistribution, extreme right wants no redistribution - so the right answer must be modest redistribution.' The merits of redistribution don't resolve to the average of political positions on it. Source: UK wealth tax debate Issue: wealth tax NHS funding debate: 'some say crisis, some say fine, reality is probably somewhere in between.' The evidential question isn't resolved by averaging the positions. Source: UK health policy discourse Issue: nhs_funding	non-engagement	semantic_manipulation	classical	established	false compromise, middle ground fallacy, golden mean fallacy, argumentum ad temperantiam	Assuming that the middle position between two views is always the most correct or reasonable one - that the truth must lie somewhere between two extremes. The middle ground between two positions is not necessarily correct; sometimes one extreme is right and the other wrong. Conflates 'moderate' with 'accurate'.	3
Nirvana Fallacy nirvana_fallacy Aliases perfect solution fallacy, best vs. good fallacy, perfect is the enemy of good Distinguishing Features Distinct from legitimate criticism of policy design (which argues for specific improvements). The nirvana fallacy dismisses a proposal because it falls short of perfection, not because a better realistic alternative exists. Heavily used in policy debate to defeat reform proposals without engaging with them. Distinguishes From false_dilemmaslippery_slopeargument_to_moderation Common Co-occurrences false_dilemmacritique_without_alternativespecial_pleading Crossover Debate Terminology None Examples 'The wealth tax proposal isn't perfect - it has loopholes and avoidance risks - so we shouldn't implement it.' The comparison should be against the status quo, not against a hypothetical perfect tax. Source: UK wealth tax debate Issue: wealth tax 'The NHS isn't perfect - there are inefficiencies - so we shouldn't simply increase its funding.' Imperfection isn't an argument against investment without a comparison to realistic alternatives. Source: UK health policy debate Issue: nhs_funding 'No immigration system is perfectly fair - therefore we shouldn't try to reform the current one.' The realistic alternative to an imperfect reform is an imperfect status quo, not a perfect system. Source: UK immigration policy debate Issue: immigration 'Prebunking isn't 100% effective - therefore it's not worth investing in.' The relevant question is whether it's more effective than the realistic alternative, not whether it achieves perfection. Source: Media literacy policy debate Issue: media discourse	non-engagement	semantic_manipulation	both	established	perfect solution fallacy, best vs. good fallacy, perfect is the enemy of good	Rejecting a realistic, imperfect solution by comparing it unfavourably to an idealised perfect solution that doesn't exist or isn't available - rather than comparing it to the realistic alternatives. The relevant comparison is between the available options, not between the available option and a hypothetical ideal.	4
Continuum Fallacy continuum_fallacy Aliases fallacy of the beard, heap paradox (fallacy form), line-drawing fallacy, sorites fallacy (applied) Distinguishing Features The sorites paradox shows that concepts like 'heap' or 'bald' resist precise definition; the continuum fallacy exploits this to claim the concepts are meaningless. In policy, this often appears as 'where do you draw the line?' used as a refutation rather than as a genuine design question. Distinguishes From false_dilemmaslippery_slopesweeping_generalisation Common Co-occurrences slippery_slopefalse_dilemmaspecial_pleading Crossover Debate Terminology None Examples 'Where exactly is the line between wealthy and not wealthy?

Source: UK wealth tax debate Issue: wealth tax 'Where does legitimate immigration end and illegal immigration begin? It's all a matter of degree.' The existence of hard cases at the boundary doesn't eliminate the distinction between paradigm cases. Source: UK immigration discourse Issue: immigration 'At what point exactly does regulation become overregulation? You can't specify - so any regulation could be overregulation.' The difficulty of the precise line doesn't eliminate the distinction. Source: UK AI regulation debate Issue: ai_regulation	non-engagement	formal_structure	classical	established	fallacy of the beard, heap paradox (fallacy form), line-drawing fallacy, sorites fallacy (applied)	Rejecting a distinction or classification because a precise boundary cannot be drawn - arguing that because the line between A and not-A is fuzzy, the distinction does not exist. The inability to draw a precise line does not mean there is no meaningful difference between paradigm cases at each extreme.	3
Suppressed Correlative suppressed_correlative Aliases redefining the alternative, eliminating the contrast class Distinguishing Features Related to persuasive definition and no_true_scotsman but specifically about the elimination of contrast classes. The definitional move makes the surviving term vacuously true. Distinguishes From persuasive_definitionno_true_scotsmandefinitional_retreat Common Co-occurrences persuasive_definitionequivocationsemantic_dodge Crossover Debate Terminology None Examples 'All economic behaviour is natural because humans are natural creatures.' Redefining 'natural' to include all human behaviour eliminates the natural/artificial distinction in economics. Source: Economic philosophy debate Issue: wealth tax 'All immigration is in some sense legal because humans have always migrated.' Redefining legal migration to include historical movement collapses the legal/illegal distinction. Source: UK immigration discourse Issue: immigration	definition	semantic_manipulation	classical	established	redefining the alternative, eliminating the contrast class	Redefining a correlative term - a term that derives meaning from its contrast with another - in a way that makes one of the pair impossible, thereby making the surviving term apply to everything and lose its meaning. If 'natural' is redefined to include everything, nothing can be 'unnatural', and the natural/unnatural distinction collapses.	2
Moving the Goalposts moving_the_goalposts Aliases goalpost shifting, changing the criteria, raising the bar, special pleading (evidential) Distinguishing Features Distinct from legitimate updating of standards: if new information genuinely changes what evidence is needed, that is not the fallacy. The fallacy is motivated goalpost shifting - the new criteria are introduced specifically to avoid concession. Platform-native contexts amplify it because the original standard can be forgotten as conversations evolve across threads. Distinguishes From special_pleadingkafkatrappingbegging_the_question Common Co-occurrences special_pleadingkafkatrappingsealioning Crossover Debate Terminology None Examples 'Show me peer-reviewed evidence for the wealth tax.'

The standard keeps shifting as each version is met. Source: UK wealth tax debate, generic pattern Issue: wealth tax Climate science: early demands for 'more evidence' were met; then 'better models'; then 'longer time series'; then 'direct attribution'. Each met standard produced a new one rather than concession. Source: Climate science communication research Issue: ai_regulation Amazon seller dispute: 'Provide your invoice.'

[Largest vote share since 1945 in 2017.] 'That wasn't a real test - he didn't actually win.' Goalpost shifted from votes to seats. Source: UK Labour Party electoral discourse, 2017 Issue: electoral politics	non-engagement	semantic_manipulation	both	established	goalpost shifting, changing the criteria, raising the bar, special pleading (evidential)	Changing the criteria for success or the standards of evidence required after an argument has been met - demanding new evidence or a different standard when the original challenge has been satisfied, rather than accepting that the original burden has been discharged. A form of bad-faith argumentation that makes a position unfalsifiable.	4
Special Pleading special_pleading Aliases double standard, applying the exception, ad hoc exemption Distinguishing Features Distinct from legitimate exceptions: genuine exceptions are principled - they apply consistently to all cases meeting the specified criteria. Special pleading introduces ad hoc exemptions whose only consistent feature is benefiting the speaker's preferred side. The diagnostic question: would the speaker apply the same exception if the positions were reversed? Distinguishes From ad_hominem_tu_quoquemoving_the_goalpostsbegging_the_question Common Co-occurrences moving_the_goalpostsad_hominem_tu_quoquefalse_equivalence Crossover Debate Terminology None Examples 'Strikes by public sector workers are irresponsible and hurt ordinary people.

Source: SellerSpace context; special pleading applied to platform governance Issue: platform economics	non-engagement	semantic_manipulation	classical	established	double standard, applying the exception, ad hoc exemption	Applying different standards to one's own position or group than to opposing positions or groups - claiming an exception to a general rule for oneself or one's allies without providing a principled justification for why the exception applies. A form of intellectual inconsistency that is almost universal in political discourse.	4
Argument from Incredulity argument_from_incredulity Aliases personal incredulity fallacy, divine fallacy, appeal to common sense Distinguishing Features Distinct from legitimate claims of implausibility based on evidence: 'I find this hard to believe because the evidence makes it implausible' is different from 'I find this hard to believe therefore it isn't true'. The fallacy is treating the psychological difficulty of belief as evidence against truth. Distinguishes From appeal_to_probabilitybegging_the_questionmotivated_reasoning Common Co-occurrences motivated_reasoningbackfire_effectappeal_to_the_masses Crossover Debate Terminology None Examples 'I just can't believe that the richest 1% own more than the bottom 50% combined - those figures must be wrong.' The incredulity doesn't address the methodology. Source: UK wealth inequality discourse Issue: wealth tax 'It seems incredible that the government would knowingly underfund the NHS - therefore they haven't.' Implausibility to the speaker is not evidence. Source: UK health policy debate Issue: nhs_funding Creationist arguments: 'The complexity of the eye is so incredible it couldn't have evolved by chance.' Personal incredulity about evolutionary mechanisms is not an argument against the evidence. Source: Science-religion discourse - classic example Issue: media discourse 'I find it hard to believe that a coordinated influence operation could have changed the Brexit vote - it seems too conspiratorial.' The difficulty of believing it doesn't establish it didn't happen. Source: UK Brexit discourse Issue: electoral politics	non-engagement	evidence_quality	classical	established	personal incredulity fallacy, divine fallacy, appeal to common sense	Claiming that something must be false (or must have a different explanation) because it is difficult to believe or seems implausible to the speaker. Personal incredulity is not evidence - many true things are counterintuitive, and many false things seem plausible.	4
Historian's Fallacy historians_fallacy Aliases hindsight bias (argument form), retrospective knowledge projection Distinguishing Features Distinct from hindsight bias (a cognitive error) by being a fallacy in historical argument. Relevant to political accountability debates where past decisions are criticised using information only available after the fact. Distinguishes From post_hocfalse_causemotivated_reasoning Common Co-occurrences post_hocfalse_causead_hominem Crossover Debate Terminology None Examples 'Blair should have known the Iraq intelligence was flawed - the errors were obvious.' This assumes Blair had access to the post-war assessments before the war.

Applying post-event knowledge to pre-event decision-making. Source: UK COVID inquiry discourse Issue: public health 'Anyone could see the 2008 financial crisis coming - the banks were reckless.' Some did foresee it; the question is whether the knowledge needed was available at the time of decisions.

Coined by David Hackett Fischer (1970). The error misrepresents the epistemic situation of historical actors.	3
Hasty Conclusion hasty_conclusion Aliases premature conclusion, jumping to conclusions, insufficient evidence conclusion Distinguishing Features More of a process failure than a structural fallacy. Very common in rolling news coverage and social media where audiences are invited to draw conclusions from incomplete early reports. Distinguishes From hasty_generalisationpost_hocargument_from_incredulity Common Co-occurrences hasty_generalisationcherry_pickingmisinformation_latency Crossover Debate Terminology None Examples Early COVID reports from one country used to conclude definitively about global vaccine effectiveness before sufficient data existed.

Source: UK rolling news, documented pattern Issue: media discourse	non-engagement	evidence_quality	classical	established	premature conclusion, jumping to conclusions, insufficient evidence conclusion	Drawing a conclusion before sufficient evidence has been gathered - reaching a verdict before the available evidence warrants it. Related to hasty generalisation (from too few cases) but broader: the conclusion may not involve generalisation but simply demands more evidence before it is justified.	3
Appeal to Hypocrisy appeal_to_hypocrisy Aliases tu quoque (broad), you too (credibility), hypocrite's dismissal Distinguishing Features The hypocrisy is relevant to the arguer's credibility and consistency, but not to the truth of the claim. A hypocritical person can make valid arguments. Distinct from tu quoque (which specifically points out the critic doing the same thing) by covering any inconsistency between the arguer's position and behaviour. Distinguishes From ad_hominem_tu_quoquead_hominemgenetic_fallacy Common Co-occurrences ad_hominemad_hominem_tu_quoquewhataboutism Crossover Debate Terminology None Examples 'Gary Lineker criticises immigration policy from his wealthy home - what does he know about ordinary people's concerns?'

The salary may be inconsistent with the message but doesn't address the economic arguments. Source: UK wealth inequality discourse Issue: wealth tax 'The environmentalist flew to the climate conference. They're a hypocrite so we needn't take their arguments seriously.' Hypocrisy doesn't invalidate the argument. Source: Climate discourse Issue: ai_regulation	non-engagement	psychological_rhetoric	classical	established	tu quoque (broad), you too (credibility), hypocrite's dismissal	Attempting to discredit a position by pointing out that the person arguing for it does not practice what they preach - dismissing an argument because the arguer is hypocritical. The hypocrisy may be genuine but is irrelevant to the argument's validity. Different from ad_hominem_tu_quoque in being broader: any hypocrisy, not specifically 'you do the same thing'.	3
Bulverism bulverism Aliases explaining away, psychogenetic fallacy, motive projection dismissal Distinguishing Features The explanation of why someone believes something cannot precede a demonstration that what they believe is false. Psychological or sociological explanation of belief may be interesting and relevant context - but it is not a substitute for engaging with the argument's content. Very common in political discourse where opponents' views are 'explained' by their interests, upbringing, or psychological needs. Distinguishes From ad_hominem_circumstantialgenetic_fallacypoisoning_the_well Common Co-occurrences genetic_fallacyad_hominem_circumstantialpoisoning_the_well Crossover Debate Terminology None Examples 'Of course Gary Stevenson supports a wealth tax - he grew up poor and resents the wealthy. That's what this is really about.' This explains his belief without engaging with whether his economic analysis is correct. Source: UK wealth tax discourse Issue: wealth tax 'People support Brexit because they're nostalgic and fearful of change - it's not a rational position.' Psychological explanation substituted for engagement with the arguments. Source: UK Brexit discourse Issue: electoral politics 'She defends the NHS because she works in it - naturally she would say that.' Her employment explains the motivation but doesn't address whether her arguments about NHS funding are sound. Source: UK health policy discourse Issue: nhs_funding 'Young people support radical climate policy because they're idealistic and haven't yet understood how the economy works.' Dismissal via developmental explanation rather than argument engagement. Source: UK climate discourse Issue: ai_regulation	non-engagement	psychological_rhetoric	classical	established	explaining away, psychogenetic fallacy, motive projection dismissal	Assuming that someone is wrong and then explaining the psychological, sociological, or biographical reason why they believe the false thing - without first demonstrating that they are wrong. Coined by C.S. Lewis (1941). The move skips the step of engaging with the argument and substitutes an account of why the person is motivated to believe it.	4
Kafkatrapping kafkatrapping Aliases accusation-as-proof, denial as evidence, unfalsifiable accusation Distinguishing Features Distinct from moving the goalposts (which changes the standard for success) by specifically weaponising the denial itself as evidence. The logic: 'If you were innocent you would not have denied it' - but denial is what any accused person, innocent or guilty, would do. Makes productive discourse impossible because any response confirms the premise. Distinguishes From moving_the_goalpostsbegging_the_questionloaded_question Common Co-occurrences moving_the_goalpostsloaded_questionsealioning Crossover Debate Terminology None Examples Online discourse: 'Admit that you have racial bias.' 'I don't believe I do.' 'That denial proves you're not examining your privilege - a truly self-aware person would acknowledge it.' Any response to the accusation confirms it. Source: Online identity politics discourse Issue: social policy 'Do you think your company discriminates against sellers?' 'No.' 'The fact that you deny it shows how deeply embedded the discrimination is.' Amazon seller discourse applied.

'That's exactly what they'd say - the absence of evidence is proof of the cover-up.' Source: Conspiracy theory discourse, generic Issue: media discourse Political smear: 'Prove you're not corrupt.' Any response - denial, silence, requesting evidence - is treated as further evidence of guilt. Source: UK political attack discourse, generic Issue: electoral politics	manipulation	psychological_rhetoric	both	established	accusation-as-proof, denial as evidence, unfalsifiable accusation	Structuring an accusation so that denial of it is itself treated as proof of its truth - making the accusation unfalsifiable by design. The name references Kafka's The Trial, in which Josef K. is accused of an unspecified crime and finds that attempting to defend himself is treated as evidence of guilt. Common in online discourse where admitting uncertainty about one's own prejudices is demanded, then used as confession.	4
False Precision false_precision Aliases spurious quantification, pseudo-precision, false specificity Distinguishing Features Distinct from phantom_quantification in that false precision may involve real-but-misapplied data expressed with spurious exactness (e.g. '73% of people prefer X'). Phantom quantification involves numbers that may be entirely fabricated with no traceable source. Distinguishes From phantom_quantificationmalinformationappeal_to_authority Common Co-occurrences phantom_quantificationmechanistic_launderingappeal_to_false_authoritylexical_credentialism Crossover Debate Terminology None Examples 'Studies show 87% of people who try this diet lose weight in the first month.'

Source: UK immigration debate, 2024–2026 Issue: immigration	manipulation	evidence_quality	both	established	spurious quantification, pseudo-precision, false specificity	Using a specific number or quantitative claim to simulate scientific authority when no reliable measurement underlies the figure. The specificity is rhetorical, not empirical - it makes a claim feel falsifiable and therefore credible without actually being grounded.	3
Appeal to Contrarianism appeal_to_contrarianism Aliases contrarian fallacy, anti-mainstream bias, maverick appeal Distinguishing Features Distinct from appeal_to_novelty (new = better) and appeal_to_tradition (old = better). Contrarianism specifically inverts authority: mainstream = suspect, therefore heterodox = credible. Often combined with performed_empiricism - the speaker frames their contrarianism as rigorous independent thinking. Distinguishes From appeal_to_noveltyappeal_to_traditionperformed_empiricismgenetic_fallacy Common Co-occurrences performed_empiricismepistemic_immunisationappeal_to_false_authoritylexical_credentialism Crossover Debate Terminology None Examples 'They don't want you to know this, but the mainstream medical establishment has been suppressing evidence for decades.'

Source: UK economic commentary, 2024–2026 Issue: wealth_tax	manipulation	psychological_rhetoric	networked	established	contrarian fallacy, anti-mainstream bias, maverick appeal	Treating disagreement with mainstream or consensus views as itself evidence of correctness. The mere fact that a position is heterodox is taken to validate it, rather than engagement with the actual arguments for and against.	3
Barnum Effect barnum_effect Aliases forer effect, personal validation fallacy, symptom scatter, universal resonance Distinguishing Features The statements are not false - they are true of almost everyone. The manipulation lies in implying specificity and diagnostic insight while actually casting the widest possible net. In health rhetoric, takes the form of listing diffuse symptoms (tiredness, anxiety, poor sleep) that virtually any audience member will experience, manufacturing a sense of personal diagnosis. Distinguishes From appeal_to_emotionmalinformationfalse_precision Common Co-occurrences mechanistic_launderingnarrative_inoculationfalse_causal_chainlexical_credentialism Crossover Debate Terminology None Examples 'Your energy drops, your anxiety increases, your metabolism slows, your sleep worsens' - presented as symptoms of magnesium depletion, but applies to virtually any adult.

Named after P.T. Barnum; experimentally demonstrated by Bertram Forer (1949). Applied rhetorically in health, political, and personality content to manufacture felt relevance.	3
Weasel Words weasel_words Aliases hedge words, non-denial denial, plausible deniability phrasing Distinguishing Features Distinct from semantic_dodge, which actively redefines terms to escape accountability. Weasel words avoid commitment by vagueness rather than redefinition. Common markers: 'some say', 'many people feel', 'there is evidence that', 'it has been suggested', 'up to X%'. Distinguishes From semantic_dodgeequivocationsemantic_softening Common Co-occurrences epistemic_cowardicesemantic_dodgeappeal_to_ignorancefalse_balance Crossover Debate Terminology None Examples 'Some experts believe climate projections may have been slightly overstated.'

Source: Health supplement and diet marketing Issue: health misinformation	definition	semantic_manipulation	both	established	hedge words, non-denial denial, plausible deniability phrasing	Using vague, qualifying, or deliberately ambiguous language to make a claim that sounds strong while preserving deniability. The words appear to commit but actually evacuate the claim of testable content. Named for the weasel's supposed ability to suck the contents from an egg while leaving the shell intact.	3
Cargo Cult Science cargo_cult_science Aliases pseudoscience rhetoric, scientific mimicry, rhetorical cargo cult science Distinguishing Features Operates at the methodological level. The practitioner may be sincere. Distinct from mechanistic_laundering, which is a purely rhetorical variant - performing the questions of scientific inquiry without delivering the answers. Cargo cult science involves actual (flawed or cherry-picked) studies; mechanistic laundering involves no studies at all. Distinguishes From mechanistic_launderingappeal_to_false_authoritycherry_pickingfalse_precision Common Co-occurrences false_precisionphantom_quantificationcherry_pickingappeal_to_false_authoritylexical_credentialism Crossover Debate Terminology None Examples Anti-vaccine movement citing retracted Wakefield study and selectively citing VAERS reports as causal evidence.

Coined by Richard Feynman (1974 Caltech commencement address). The practitioner follows the external forms of science - studies, statistics, mechanisms - while missing the integrity checks that make science reliable.	3
False Causal Chain false_causal_chain Aliases causal cascade fallacy, post hoc chain, sequential non sequitur Distinguishing Features Distinct from slippery_slope, which projects a speculative future causal chain. False causal chain presents an asserted present mechanism as already established. The repeated logical connectives ('so', 'therefore', 'which means') are the tell - they are doing argumentative work they have not earned. Distinguishes From slippery_slopepost_hoc_ergo_propter_hocfalse_equivalencecascade_causation Common Co-occurrences mechanistic_launderingfalse_precisionbarnum_effectappeal_to_emotion Crossover Debate Terminology None Examples 'You're already borderline deficient in magnesium.

So immigration is making working families homeless.' Each link asserted, none evidenced. Source: UK immigration debate, generic Issue: immigration 'Wealth taxes reduce investment. Less investment means fewer jobs. Fewer jobs means lower tax receipts. So wealth taxes ultimately hurt the poor.' Chain presented as inevitable; none of the links are established. Source: UK wealth tax debate Issue: wealth_tax	non-engagement	formal_structure	both	established	causal cascade fallacy, post hoc chain, sequential non sequitur	Asserting a sequence of causal steps - each presented as following necessarily from the last - without establishing any of the individual links. The syntactic structure of logical inference (so… therefore… which means…) is used to perform inevitability without providing it. Each step in the chain is a non sequitur dressed as modus ponens.	3
Epistemic Immunisation epistemic_immunisation Aliases unfalsifiability by design, refutation-proofing, pre-emptive insulation Distinguishing Features The tell is that the frame provides an answer for every possible counter-move. 'If you disagree, that proves you're part of the problem.' 'The fact that mainstream experts reject this shows how suppressed it is.' Any attack becomes evidence. Related to kafkatrapping but broader - applies to belief systems, not just accusations.

The belief becomes self-sealing: counter-evidence is dismissed as proof of conspiracy, bias, or the opponent's bad faith. Distinct from simply being hard to falsify - epistemic immunisation is an active rhetorical strategy to pre-empt refutation.	3
Mechanistic Laundering mechanistic_laundering Aliases rhetorical cargo cult science, performed mechanism, question-as-answer Distinguishing Features Distinct from cargo_cult_science, which involves actual (if flawed) studies and data. Mechanistic laundering involves no evidence at all - the rhetorical performance of asking the right questions substitutes for answering them. Extremely common in wellness, health influencer, and alternative medicine content. The speaker appears more rigorous than someone making a naked assertion, but delivers the same epistemological content. Distinguishes From cargo_cult_sciencefalse_causal_chainlexical_credentialismperformed_empiricism Common Co-occurrences false_causal_chainphantom_quantificationlexical_credentialismbarnum_effectfalse_precision Crossover Debate Terminology None Examples 'How does it happen?

Followed by a narrative with no cellular biology. Source: Generic wellness content Issue: health misinformation 'The real question is: what does mass immigration actually do to social cohesion? Let me walk you through the mechanism.' - followed by anecdote and assertion. Source: UK political commentary, generic Issue: immigration	manipulation	psychological_rhetoric	both	coined	rhetorical cargo cult science, performed mechanism, question-as-answer	Invoking the language and structure of mechanistic physiological or causal explanation - causation, sequence, specificity - without actually providing it. The questions of scientific inquiry ('How does it happen? What happens in the body?') are performed as if they constitute an explanation, while the answers that follow are mere assertion. The form of rigorous thinking is adopted; the substance is not delivered.	3
Phantom Quantification phantom_quantification Aliases fabricated statistic, sourceless number, ghost figure Distinguishing Features The number functions rhetorically, not evidentially. Its purpose is to make a claim feel falsifiable and therefore credible - not to be verified. A phantom figure is one that, when traced, leads nowhere: no study, no methodology, no primary source. The self-contradiction test: if the same speaker gives two different figures for the same fact, at least one is phantom. Distinguishes From false_precisionmalinformationcherry_picking Common Co-occurrences false_precisionmechanistic_launderingcargo_cult_sciencelexical_credentialism Crossover Debate Terminology None Examples Speaker opens with '4 molecules of magnesium to process one molecule of sugar' and closes with '54 molecules of magnesium for one of sugar' - the self-contradiction proves neither figure has a source. Source: Wellness influencer transcript, 2026 Issue: health misinformation 'There are 1.7 million illegal immigrants in the UK' - a figure cited across multiple media outlets with no auditable methodology. Source: UK immigration debate, 2024–2026 Issue: immigration 'The NHS spends £6 billion a year on health tourism.' Figure originated in a government report later retracted; continues to circulate as if peer-reviewed. Source: UK NHS/immigration discourse Issue: nhs_funding	manipulation	evidence_quality	both	coined	fabricated statistic, sourceless number, ghost figure	Deploying a specific number that gestures toward a citable, peer-reviewed fact but has no traceable source - the number may be entirely fabricated, or garbled beyond recognition from a real figure. Distinct from false_precision (which involves real-but-misapplied data expressed with spurious exactness): phantom quantification involves a number that cannot be traced back to any legitimate origin. The internal contradiction between different versions of the same figure (e.g., 4 molecules vs 54 molecules in the same paragraph) is a diagnostic tell.	3
Lexical Credentialism lexical_credentialism Aliases vocabulary borrowing, jargon credentialing, technical register mimicry Distinguishing Features Distinct from appeal_to_authority, where the credibility of a named person or institution is invoked. Lexical credentialism invokes no authority - it borrows the vocabulary of authority fields. The terms are not explained or sourced; they are signals. Markers: technical-sounding terminology used without definition, citation, or qualification, in contexts where the speaker has no demonstrated domain expertise. Distinguishes From appeal_to_authorityappeal_to_false_authoritycargo_cult_sciencemechanistic_laundering Common Co-occurrences performed_empiricismmechanistic_launderingphantom_quantificationfalse_precision Crossover Debate Terminology None Examples 'Magnesium is essential for nervous system regulation, ATP synthesis, and glucose transport across cell membranes.' Terms deployed without citation in a wellness TikTok; vocabulary signals biochemistry expertise the speaker does not demonstrate. Source: Wellness influencer transcript, 2026 Issue: health misinformation 'At the macroeconomic level, the velocity of money and multiplier effects mean that wealth redistribution is self-defeating.' Economic vocabulary used without evidence or citation in a political podcast. Source: UK wealth tax debate Issue: wealth_tax 'The immunological evidence clearly shows that natural immunity confers broader T-cell and B-cell protection than vaccine-induced immunity.' Immunological vocabulary deployed without citation in anti-vaccination content. Source: Anti-vaccination discourse, UK/US Issue: health misinformation	manipulation	psychological_rhetoric	both	coined	vocabulary borrowing, jargon credentialing, technical register mimicry	Using the vocabulary of a technical or academic domain as a substitute for demonstrated expertise or cited evidence. No authority is explicitly claimed - instead, the lexical field of expertise (scientific, medical, legal, economic) is deployed to transfer domain credibility to claims that have no underlying credentialed basis. The speaker inhabits the linguistic world of science without inhabiting its epistemic standards.	3
Performed Empiricism performed_empiricism Aliases false rigour claim, epistemic identity claim, I-just-want-the-facts move Distinguishing Features Distinct from epistemic_immunisation, which is a structural property of the argument (counter-evidence is reinterpreted as confirmation). Performed empiricism is a presentational move - a self-attributed identity claim deployed rhetorically before the argument is made. Extremely common in wellness, heterodox economics, and alternative media. The tell is temporal: the claim of rigour precedes the argument, not follows from it. Distinguishes From epistemic_immunisationappeal_to_contrarianismlexical_credentialismepistemic_cowardice Common Co-occurrences appeal_to_contrarianismlexical_credentialismmechanistic_launderingepistemic_immunisation Crossover Debate Terminology None Examples 'I never wanted the slogans.

Stated before presenting selectively chosen statistics without methodology.

Stated before an argument with no cited evidence. Source: Heterodox economics media, generic Issue: wealth_tax	manipulation	psychological_rhetoric	networked	coined	false rigour claim, epistemic identity claim, I-just-want-the-facts move	Pre-emptively occupying the identity of a rigorous, evidence-based thinker as a substitute for actually demonstrating rigour or providing evidence. The speaker signals their critical-thinker status ('I don't want slogans, I want the science'; 'I just follow the data') at precisely the moment no evidence is provided, functioning as inoculation against scrutiny. The claimed epistemic virtue does the work the evidence should do.	3
Narrative Inoculation narrative_inoculation Aliases conversion framing, insight narrative, epistemic autobiography Distinguishing Features Distinct from testimonial fallacy, where the authority of a named person is invoked. Narrative inoculation does not invoke authority - it builds parasocial identification through shared journey framing. The inoculation function is specific: the conversion narrative makes the audience resistant to correction by positioning correction as an attack on the speaker's personal growth story. Common in wellness, political radicalisation, and faith-based content.

And the more I asked, the more I couldn't ignore.' Source: Anti-vaccination discourse, UK Issue: health misinformation	manipulation	psychological_rhetoric	networked	coined	conversion framing, insight narrative, epistemic autobiography	Structuring persuasive content as a personal story of epistemic conversion - 'I used to think X, but then I discovered Y, and everything changed' - in a way that models the desired response in the audience and emotionally insulates the central claim from critical evaluation. The narrative arc pre-validates the claim: if understanding this changed everything for the speaker, the audience is primed to receive it as transformative rather than scrutinise it as a factual assertion. The emotional identification with the speaker's past self (pre-knowledge) positions the audience as on the same journey, making external correction feel like an attack on a trusted peer.	3
Dialectic dialectic Aliases dialectike, critical discussion, cooperative inquiry Distinguishing Features Dialectic is defined by its orientation: truth-seeking, cooperative, process-valuing. The dialectical arguer is willing to be wrong, acknowledges strong counter-arguments, stays on the proposition, and treats the exchange as a shared inquiry. Contrast with eristic, where the exchange is a competition to be won regardless of truth. Distinguishes From eristic Common Co-occurrences elenchusendoxapragma_dialectics Crossover Debate Terminology None Examples A select committee hearing where a minister concedes a valid counter-point from the opposition and revises their stated position accordingly. Source: UK parliamentary discourse, generic Issue: epistemic quality Socrates in the Meno: 'Let us inquire together whether virtue is teachable, rather than assert it.' The process of inquiry is valued over the outcome. Source: Plato, Meno Issue: epistemic quality	concept	-	both	established	dialectike, critical discussion, cooperative inquiry	The method of reasoned dialogue oriented toward truth rather than victory. For Plato, the highest form of philosophical inquiry - the ascent toward knowledge through question and answer. For Aristotle, structured exchange from reputable premises (endoxa) using valid inference. In pragma-dialectics (van Eemeren & Grootendorst), formalised as 'critical discussion' governed by ten rules of legitimate argumentative conduct. The positive pole of the Dialectic/Eristic axis; the theoretical target state that the DIM quality score measures proximity to.	2
Eristic eristic Aliases eristike, adversarial debate, victory-oriented argument Distinguishing Features The diagnostic is orientation, not surface behaviour. An eristic arguer may use valid-seeming arguments - the eristicism lies in the willingness to use invalid ones when valid ones are unavailable, and in treating refutation as defeat rather than correction. The entire taxonomy of fallacies catalogued in DIM constitutes a map of eristic moves. Distinguishes From dialectic Common Co-occurrences straw_manad_hominemgish_gallopepistemic_immunisationperformed_empiricism Crossover Debate Terminology None Examples A political interviewee who responds to every direct question with a pivot to a prepared talking point, treating the interview as a performance rather than an inquiry.

Source: Plato, Gorgias; Aristotle, Sophistical Refutations Issue: epistemic quality	concept	-	both	established	eristike, adversarial debate, victory-oriented argument	Debate oriented toward winning rather than truth. Aristotle's term for the bad-faith counterpart to dialectic - argument that uses the forms of reasoning while being indifferent to their validity, provided they produce the desired outcome. The negative pole of the Dialectic/Eristic axis. An eristic arguer is interested in controlling the outcome of the exchange; a dialectic arguer is interested in the quality of the process. Named after Eris, the Greek goddess of discord.	2
Elenchus elenchus Aliases Socratic refutation, cross-examination refutation, contradiction exposure Distinguishing Features The elenchus does not introduce new evidence or counter-claims; it works entirely from the opponent's own commitments. This makes it unusually difficult to deflect - the opponent cannot accuse the questioner of changing the subject, since the questioner has introduced nothing new. The goal is not humiliation but genuine revision of belief. Effective against epistemic_immunisation and performed_empiricism because it forces engagement with the internal logic of the position. Distinguishes From steelmanningreductio_ad_absurdumloaded_question Common Co-occurrences dialecticaporiasteelmanning Crossover Debate Terminology None Examples Socrates in the Republic: rather than arguing against Thrasymachus's definition of justice, draws out consequences of it that Thrasymachus himself rejects. Source: Plato, Republic Book I Issue: epistemic quality A journalist who, rather than challenging a politician's claim directly, asks: 'You said X last year and Y today - which is correct?' - forcing contradiction exposure from the politician's own record. Source: UK political interviewing, generic Issue: epistemic quality	counter_technique	counter_techniques	classical	established	Socratic refutation, cross-examination refutation, contradiction exposure	Socratic cross-examination: the method of refuting a position by drawing out its internal contradictions through careful questioning. The questioner accepts the opponent's premises and follows them to a conclusion that contradicts something the opponent also holds to be true, revealing inconsistency. The outcome - aporia (genuine puzzlement) - is treated as a legitimate and valuable endpoint, not a failure.	2
Enthymeme enthymeme Aliases rhetorical syllogism, suppressed premise argument Distinguishing Features The suppressed premise is not random - it is chosen because the arguer knows the audience will supply it automatically. This means the arguer can rely on a premise they would not defend openly. Analysis: always ask 'what must be true for this argument to work?' The answer is the suppressed premise, and that is where the real argumentative weight - and often the fallacy - lives. Distinguishes From syllogismbegging_the_questionloaded_question Common Co-occurrences genetic_fallacyad_hominemappeal_to_traditiondog_whistle Crossover Debate Terminology None Examples 'Gary Stevenson is not an academic economist.' Suppressed premise: academic economists are the only legitimate commentators on economic inequality. Surfacing it reveals the No True Scotsman move. Source: Rory Stewart / Gary Stevenson discourse, UK 2024 Issue: wealth_tax 'These are our communities.' - UK immigration rhetoric. Suppressed premise: immigrants are not part of 'our' communities. The enthymeme does discriminatory work that the explicit premise denies. Source: UK immigration debate, generic Issue: immigration 'We can't afford not to fund the NHS properly.' Suppressed premise: the current level of funding is inadequate. The debate-worthy claim is embedded in the unspoken assumption. Source: UK NHS debate, generic Issue: nhs_funding	concept	-	both	established	rhetorical syllogism, suppressed premise argument	A syllogism with one premise left unstated, relying on a shared assumption the audience supplies. Aristotle identified it as the workhorse of persuasive political and forensic argument. The unstated premise is typically a cultural assumption, value, or stereotype - which is precisely why enthymemes are effective: the audience actively participates in completing the argument, making it feel more convincing than a fully spelled-out claim. Surfacing the suppressed premise is often the most analytically powerful move available.	3
Endoxa endoxa Aliases reputable opinions, common ground premises, dialectical starting points Distinguishing Features Endoxa are not infallible - they can be revised through dialectic. Their use is legitimate when they genuinely represent shared reasonable opinion; illegitimate when they are contested views dressed as consensus, or when an enthymeme smuggles a non-endoxic premise as if it were endoxic. The distinction between genuine endoxa and manufactured consensus (astroturfing, appeal_to_the_masses) is analytically important. Distinguishes From appeal_to_the_massesappeal_to_authorityconsensus Common Co-occurrences enthymemedialecticappeal_to_the_massesastroturfing Crossover Debate Terminology None Examples 'Most economists agree that sustained growth requires investment.' Using genuine expert consensus as a dialectical starting point - legitimate endoxic premise. Source: UK wealth tax debate Issue: wealth_tax 'Everyone knows immigration has changed this country.' Framing a contested political claim as if it were endoxic - manufacturing the appearance of shared common ground. Source: UK immigration discourse, generic Issue: immigration	concept	-	both	established	reputable opinions, common ground premises, dialectical starting points	Reputable opinions used as the legitimate starting premises of dialectical argument - views held by most people, or by recognised experts, or by the wise. Aristotle's term for the proper starting points of dialectic (as opposed to scientific demonstration, which starts from first principles). Endoxa represent shared epistemic ground that both parties can accept as a basis for reasoning forward. Important for distinguishing legitimate appeals to shared understanding from illegitimate appeals to authority or popularity.	2
Pragma-Dialectics pragma_dialectics Aliases pragma-dialectical theory, critical discussion theory, van Eemeren-Grootendorst framework Distinguishing Features Pragma-dialectics treats fallacies not as logical errors but as violations of the rules of critical discussion - moves that obstruct the legitimate resolution of disagreement. This is functionally equivalent to the eristic frame: fallacious moves are eristic because they prioritise winning over resolution. The ten rules cover: freedom to advance standpoints, burden of proof, standpoint obligation, relevance, unexpressed premises, starting points, validity, argument schemes, conclusiveness, and usage. Distinguishes From dialecticeristicformal_fallacy Common Co-occurrences dialecticeristicelenchusstraw_manad_hominem Crossover Debate Terminology None Examples Rule 1 violation (Freedom rule): 'You can't seriously be arguing for a wealth tax - that's just envy politics.'

Defines ten rules (the 'commandments') that legitimate argumentative conduct must satisfy - violations of each rule correspond to named argumentative fallacies. The most rigorous modern formalisation of the Dialectic/Eristic distinction and the closest theoretical ancestor to DIM's quality score. Key texts: Argumentation, Communication, and Fallacies (1992); A Systematic Theory of Argumentation (2004).	2
Aporia aporia Aliases genuine puzzlement, productive uncertainty, dialectical impasse Distinguishing Features Aporia is a marker of intellectual honesty and openness to revision. Contrast with moving_the_goalposts, where apparent confusion is deployed to avoid conceding a point. The productive version of not knowing. Distinguishes From moving_the_goalpostsepistemic_cowardicespecial_pleading Common Co-occurrences elenchusdialecticgood_faith Crossover Debate Terminology None Examples A politician, pressed on contradictions between stated values and voting record, pauses and says: 'I think I need to revisit how I have been framing this.' Source: Hypothetical ideal exchange Issue: epistemic quality	concept	-	both	established	genuine puzzlement, productive uncertainty, dialectical impasse	The state of genuine puzzlement reached when contradictions in a position have been exposed through dialectical exchange. For Socrates and Plato, aporia is a legitimate and valuable endpoint - not a failure but a clearing away of false certainty that enables genuine inquiry to begin.	1
Topos topos Aliases topoi, commonplace, argument template, locus communis Distinguishing Features The same topos (e.g., argument from unintended consequences) recurs across wealth tax, immigration, and NHS debates with structurally identical form. Identifying the topos reveals that structurally identical arguments are being recycled across issues. Distinguishes From enthymemesyllogism Common Co-occurrences enthymemeendoxaframing Crossover Debate Terminology None Examples The 'unintended consequences' topos appears in wealth tax debate ('capital flight'), immigration debate ('pull factors'), and NHS debate ('market distortions') with identical structure. Source: UK political discourse cross-issue Issue: epistemic quality	concept	-	both	established	topoi, commonplace, argument template, locus communis	A standard argument template or 'place' (Greek: τόπος) where arguments can be found - a recurring pattern of reasoning that can be instantiated across different topics. Aristotle's Topics catalogues these common argument forms. Topoi are not fallacies; they become fallacious only when misapplied or deployed with false premises.	1
Paradoxon paradoxon Aliases paradox, counter-intuitive thesis, against received opinion Distinguishing Features Appeal_to_contrarianism is the fallacious cousin: a paradoxon is validated by argument, contrarianism is validated by its mere opposition to the mainstream. Distinguishes From appeal_to_contrarianismappeal_to_noveltyendoxa Common Co-occurrences appeal_to_contrarianismperformed_empiricismendoxa Crossover Debate Terminology None Examples Gary Stevenson's core claim - that extreme wealth concentration reduces aggregate demand - is a paradoxon relative to conventional economic wisdom. Its value depends on whether it is argued, not merely asserted. Source: UK wealth tax debate Issue: wealth_tax	concept	-	both	established	paradox, counter-intuitive thesis, against received opinion	A proposition that runs counter to received opinion (Greek: para + doxa, against opinion). In dialectical contexts, the paradoxon is a legitimate opening move that challenges endoxa and demands examination. It becomes eristic when counter-intuitiveness is performed rather than argued.	1
Ethos ethos Aliases appeal to character, speaker credibility, rhetorical ethos Distinguishing Features Legitimate ethos accompanies argument. Illegitimate ethos invocations: lexical_credentialism (borrowing expertise vocabulary), appeal_to_false_authority (citing irrelevant credentials), performed_empiricism (claiming rigour without demonstrating it). Attacking ethos is ad_hominem when it substitutes for engaging the argument. Distinguishes From appeal_to_authoritylexical_credentialismperformed_empiricismad_hominem Common Co-occurrences logosappeal_to_emotionappeal_to_authoritygenetic_fallacy Crossover Debate Terminology exordium Examples Gary Stevenson's Citibank trading background is a legitimate ethos claim when offered as context for his understanding of wealth flows - it becomes fallacious only if cited in lieu of argument. Source: UK wealth tax debate Issue: wealth_tax	concept	-	both	established	appeal to character, speaker credibility, rhetorical ethos	Aristotle's term for the appeal to the speaker's character, credibility, and trustworthiness. A legitimate rhetorical resource when earned through demonstrated expertise and good faith. Becomes fallacious when it substitutes for rather than accompanies substantive argument.	1
Logos logos Aliases appeal to reason, logical appeal, reasoned argument Distinguishing Features Pathos and ethos become fallacious when they substitute for logos. The entire taxonomy of fallacies is, in one sense, a catalogue of ways logos is faked or evaded. Distinguishes From ethosappeal_to_emotion Common Co-occurrences ethosappeal_to_emotionburden_of_proof Crossover Debate Terminology confirmatio Examples An intervention that cites specific tax incidence studies, addresses counterarguments with referenced evidence, and draws conclusions that follow validly from the premises. Source: Hypothetical high-quality intervention Issue: wealth_tax	concept	-	both	established	appeal to reason, logical appeal, reasoned argument	Aristotle's term for the appeal to reason and evidence - argument that persuades through the quality of its logic and the strength of its evidence. The positive pole of argumentative quality. What the DIM quality score measures proximity to: an intervention relying on logos is one where the persuasive work is done by the argument's validity and evidential support.	1
Kairos kairos Aliases opportune moment, rhetorical timing, timeliness Distinguishing Features Exploitative kairos: making an immigration argument immediately after a high-profile crime. Legitimate kairos: making a tax justice argument when inequality data has just been released. The distinction is whether timing serves logos or weaponises pathos. Distinguishes From appeal_to_emotionmalinformationframing Common Co-occurrences appeal_to_emotionmalinformationframingoutrage_cycle Crossover Debate Terminology None Examples Immigration restrictionist arguments made immediately after a high-profile crime - timing designed to short-circuit deliberative processing. Source: UK immigration discourse, recurring pattern Issue: immigration	concept	-	both	established	opportune moment, rhetorical timing, timeliness	The opportune moment - the right time for an argument, relative to the audience's emotional state, the news cycle, or the political context. Legitimate when timing illuminates. Manipulative when timing exploits audience vulnerability before analysis is possible.	1
Stasis stasis Aliases status, point of contention, issue identification, stasis theory Distinguishing Features Stasis confusion is one of the most common sources of unproductive political debate. Identifying the actual stasis is a counter-technique: 'Before we continue, are we agreed on what is actually in dispute here?' Distinguishes From moving_the_goalpostsred_herringwhataboutism Common Co-occurrences moving_the_goalpostsequivocationsemantic_dodge Crossover Debate Terminology quaestio Examples Wealth tax debates often conflate stasis 2 (definition: what counts as 'wealth'?) with stasis 3 (quality: is taxing it just?) - participants talk past each other. Source: UK wealth tax debate Issue: wealth_tax 'The real question is whether immigration is net positive' (stasis 3: quality). Switching to 'the real question is how many there are' (stasis 1: fact) is a different debate entirely. Source: UK immigration debate Issue: immigration	concept	-	both	established	status, point of contention, issue identification, stasis theory	The point of genuine contention in a dispute - the specific question on which the argument actually turns. Developed by Cicero and Hermogenes. Four stasis questions: (1) fact - did it happen? (2) definition - what is it? (3) quality - was it right? (4) procedure - who has authority? Many debates fail because participants argue at different stasis levels without noticing.	2
Burden of Proof burden_of_proof Aliases onus probandi, evidential burden, proof obligation Distinguishing Features Appeal_to_ignorance is the canonical violation: arguing something is true because it has not been disproved. Special_pleading claims exemption from the burden that applies to others. Distinguishes From appeal_to_ignorancespecial_pleadingpresumption Common Co-occurrences appeal_to_ignorancespecial_pleadingpresumptionfalse_equivalence Crossover Debate Terminology confirmatiotoulmin_model Examples 'Prove that wealth taxes don't cause capital flight.' - shifting burden to the opponent before providing evidence that they do. Source: UK wealth tax debate Issue: wealth_tax	concept	-	both	established	onus probandi, evidential burden, proof obligation	The obligation to support a claim with evidence. Typically rests with whoever advances a positive claim against the presumption. Shifting or evading the burden of proof is a common eristic move.	1
Presumption presumption Aliases default position, status quo presumption, argumentative default Distinguishing Features Eristic defenders of the status quo can exploit presumption by demanding ever-higher standards of proof from challengers while providing nothing themselves. Distinguishes From burden_of_proofendoxaappeal_to_tradition Common Co-occurrences burden_of_proofappeal_to_traditionspecial_pleading Crossover Debate Terminology debate_format_terms Examples In NHS privatisation debates, presumption rests with the status quo. Proponents of privatisation bear the burden of proving improvement; opponents can argue from the presumptive case. Source: UK NHS debate Issue: nhs_funding	concept	-	both	established	default position, status quo presumption, argumentative default	The default position that holds before argument begins - what wins if neither side meets its burden of proof. In formal debate, presumption typically rests with the status quo. Whoever challenges the presumption bears the initial burden of proof.	1
Good Faith good_faith Aliases bona fide, sincere engagement, genuine inquiry Distinguishing Features Sealioning is the paradigmatic simulation of good faith - bad faith disguised as sincere questioning. A good faith participant can make fallacious arguments through genuine error; a bad faith participant can make valid arguments as part of an eristic strategy. Distinguishes From dialecticeristicsealioningepistemic_cowardice Common Co-occurrences dialecticepistemic_immunisationsealioning Crossover Debate Terminology paideiadecorum Examples A debater who, when their key premise is shown to be false, says 'That's a fair point - let me revise my argument' is acting in good faith. Source: Generic debate conduct Issue: epistemic quality	concept	-	both	established	bona fide, sincere engagement, genuine inquiry	The presumption that participants are genuinely engaged in truth-seeking rather than winning - that they mean what they say, believe what they assert, and are open to revision. Good faith is the condition that makes dialectic possible; its absence is what makes an exchange eristic.	1
Conversational Implicature conversational_implicature Aliases Gricean maxims, cooperative principle, Grice's maxims Distinguishing Features Each maxim has corresponding fallacies: Quality → malinformation, false_precision, phantom_quantification; Quantity → cherry_picking, gish_gallop; Relation → red_herring, whataboutism; Manner → weasel_words, equivocation, semantic_dodge. The maxims provide principled grounding for the claim that these moves violate communicative good faith. Distinguishes From pragma_dialecticsgood_faithdialectic Common Co-occurrences good_faithpragma_dialecticsweasel_wordsred_herring Crossover Debate Terminology None Examples Quantity violation: a politician asked about a specific policy responds with a lengthy statement about general values - says more words while conveying less than required. Source: UK political interview, generic Issue: epistemic quality Relation violation: responding to NHS waiting times questions with immigration statistics. Source: UK political debate, generic Issue: nhs_funding	concept	-	both	established	Gricean maxims, cooperative principle, Grice's maxims	H.P. Grice's theory (Logic and Conversation, 1975) that communication operates under a Cooperative Principle and four maxims: Quantity (say as much as needed, no more); Quality (say only what you believe true and have evidence for); Relation (be relevant); Manner (be clear, brief, orderly). Deliberate violations of these maxims as rhetorical tactics constitute a conversational-level taxonomy of eristic moves.	2
Turn-Taking Norms turn_taking_norms Aliases floor rights, speaker transition rules, conversational turn-taking Distinguishing Features Floor-flooding (a turn-taking violation) is the interactional equivalent of gish_gallop - producing more content than the opponent can respond to within the available time. Distinguishes From gish_gallopfilibustergood_faith Common Co-occurrences gish_gallopfilibustereristic Crossover Debate Terminology parliamentary_procedure Examples A broadcast interviewee who repeatedly talks over the interviewer's questions, preventing them from establishing a line of questioning. Source: UK political broadcast, generic Issue: epistemic quality	concept	-	both	established	floor rights, speaker transition rules, conversational turn-taking	The implicit rules governing who speaks when in a dialogue - when turns begin and end, how floor rights are transferred, what constitutes a legitimate interruption. Studied systematically by Sacks, Schegloff, and Jefferson in conversation analysis (1974). Violations - interruption, talking over, floor-flooding - are eristic at the interactional level.	1
Discursive Equity discursive_equity Aliases equal participation rights, participatory parity, equal meaningful access Distinguishing Features Discursive equity failures are often structural rather than individual. Relevant to DIM's reach-weighting: the Epistemic Reach Index makes discursive inequity measurable - whose arguments actually reach people, and at what quality level. Distinguishes From epistemic_injusticegood_faithecho_chamber Common Co-occurrences epistemic_injusticefilter_bubbleagenda_settinghallins_spheres Crossover Debate Terminology None Examples The imbalance between wealth tax opponents (well-funded think tanks, media access) and proponents (lower institutional backing) creates discursive inequity independent of argument quality. Source: UK wealth tax discourse Issue: wealth_tax	concept	-	networked	coined	equal participation rights, participatory parity, equal meaningful access	The condition of equal meaningful access to participation in a discursive exchange - not merely formal permission to speak, but genuine capacity to be heard and engage on equal terms. Distinct from epistemic_injustice, which focuses on individuals as knowers. Discursive equity is a structural property of the discourse environment: platform, format, reach, and social conditions that determine whose arguments enter the debate.	1
Chilling Effect chilling_effect Aliases speech suppression, self-censorship pressure, implicit silencing Distinguishing Features Operates on the discourse environment rather than individual arguments - shapes what enters the debate before it is made. Related to epistemic_immunisation at the systemic level: a chilling effect makes certain challenges harder to voice even before they are made. Distinguishes From epistemic_immunisationagenda_settinghallins_spheres Common Co-occurrences epistemic_immunisationagenda_settinghallins_spheresbrigading Crossover Debate Terminology None Examples Threatening defamation suits against journalists investigating wealthy individuals' tax arrangements creates a chilling effect on that category of reporting. Source: UK press freedom discourse Issue: wealth_tax Coordinated pile-ons targeting academics who publish on sensitive research narrow publishable findings beyond what peer review alone would determine. Source: Academic freedom discourse, UK/US Issue: epistemic quality	networked_mechanic	networked_platform	both	established	speech suppression, self-censorship pressure, implicit silencing	The suppression of legitimate speech through implicit threat - legal, reputational, social, or professional. The mechanism is indirect: the anticipation of disproportionate consequences causes speakers to self-censor. Particularly powerful in networked environments where reputational attacks can be rapid, scalable, and disproportionate.	2
Prolepsis prolepsis Aliases anticipation, pre-emption, objection anticipation Distinguishing Features Good-faith prolepsis raises the strongest plausible objection (steelmanning one's own position). Bad-faith prolepsis raises a weak objection to create the appearance of having addressed the strong ones. The diagnostic is the quality of the objection raised. Distinguishes From steelmanningstraw_manepistemic_immunisation Common Co-occurrences steelmanningstraw_manfailure_to_steelman Crossover Debate Terminology refutatio Examples 'Now, you might say wealth taxes cause capital flight - and that's a real concern. Here's the evidence on what actually happened in Norway.' - good faith prolepsis.

Source: Generic wealth tax rhetoric Issue: wealth_tax	counter_technique	counter_techniques	both	established	anticipation, pre-emption, objection anticipation	Anticipating and pre-emptively answering an objection before it is raised. In good faith, prolepsis strengthens an argument by genuinely addressing its weaknesses. In bad faith, it raises a weak version of the objection, demolishes it, and implies the strong objection has been answered - functioning as a straw man.	2
Reductio ad Absurdum reductio_ad_absurdum Aliases reduction to absurdity, proof by contradiction, apagoge Distinguishing Features Distinct from slippery_slope: reductio reaches its conclusion through valid logical steps, not speculative causal chains. The absurd conclusion must follow necessarily, not be an exaggerated worst case. When the steps are invalid, what appears to be reductio is actually a straw man. Distinguishes From slippery_slopestraw_manfalse_dilemma Common Co-occurrences elenchussteelmanning Crossover Debate Terminology None Examples 'You say we should deport anyone who commits any crime.

Accept the opponent's premise, reason validly from it, arrive at a conclusion the opponent themselves would reject.	1
Ad Rem ad_rem Aliases to the matter, substantive engagement, argument to the substance Distinguishing Features Particularly powerful as a response to genetic_fallacy attacks: 'My background is irrelevant. Here is the argument. Is it right or wrong?' The DIM quality score is essentially a measure of whether an intervention argues ad rem or ad hominem. Distinguishes From ad_hominemgenetic_fallacysteelmanning Common Co-occurrences ad_hominemgenetic_fallacystasisburden_of_proof Crossover Debate Terminology None Examples Gary Stevenson responding to credential attacks: 'Whether I'm an academic or not doesn't bear on the argument.

The counter-move to ad_hominem and genetic_fallacy. Both a technique and a standard: the demand that argument be evaluated on its merits, not its source.	1
Ex Concessis ex_concessis Aliases from concessions, argument from admissions, arguing from granted premises Distinguishing Features Structurally strong because the opponent cannot deny the premises without contradicting themselves. Related to elenchus (which exposes internal contradictions) but distinct: ex concessis uses conceded premises to build a positive argument. Distinguishes From elenchusreductio_ad_absurdum Common Co-occurrences elenchusstasisburden_of_proof Crossover Debate Terminology None Examples A politician who previously stated 'markets should determine wages' is asked why they support minimum wage legislation. Ex concessis: 'You agreed markets should set wages. The minimum wage overrides the market. Do you now reject that principle?' Source: UK political debate Issue: epistemic quality	counter_technique	counter_techniques	both	established	from concessions, argument from admissions, arguing from granted premises	Arguing from premises the opponent has already conceded - using their own stated positions to derive a conclusion they would prefer to avoid. Eliminates the burden of establishing premises. Particularly effective when an opponent has made inconsistent concessions in different contexts.	1
Apophasis apophasis Aliases paralipsis, praeteritio, occupatio, mentioning by denial Distinguishing Features The manipulation is structural: the denial of intention to raise a point is itself the raising of it. Distinct from dog_whistle, which communicates a coded meaning to a subset of the audience; apophasis communicates openly while denying it has done so. Distinguishes From dog_whistlepoisoning_the_well Common Co-occurrences poisoning_the_wellad_hominemdog_whistle Crossover Debate Terminology None Examples 'I'm not going to make this campaign about my opponent's health - that's not the kind of politics I believe in.'

'I won't even bring up the fact that...' The speaker gets the full rhetorical benefit of planting a damaging idea while maintaining deniability.	2
Filibuster filibuster Aliases floor flooding, time-killing, procedural obstruction, speech obstruction Distinguishing Features The filibuster is gish_gallop applied to time rather than argument volume - both exploit the asymmetry between the cost of producing and the cost of responding. Both are turn-taking norm violations at scale. Distinguishes From gish_gallopturn_taking_normssealioning Common Co-occurrences gish_gallopred_herringmoving_the_goalposts Crossover Debate Terminology parliamentary_procedure Examples A select committee witness responding to questions about offshore tax arrangements with lengthy background on international tax law complexity - consuming time without addressing the question.

In formal parliamentary settings, exploits the right to speak to deny others the opportunity to vote or respond. In informal debate and media contexts, consuming available time with marginally relevant content so the core question goes unaddressed.	1
Fallacy of Composition composition_fallacy Aliases composition error, part-to-whole fallacy Distinguishing Features Distinct from division_fallacy (inferring part from whole). The fallacy is only present when the property does not compose - context-sensitivity is the diagnostic. Distinguishes From division_fallacyhasty_generalisationfalse_equivalence Common Co-occurrences division_fallacyhasty_generalisation Crossover Debate Terminology None Examples 'Each individual business decision is profit-maximising; therefore the economy is optimally efficient.'

Source: UK immigration debate Issue: immigration	formal_fallacy	formal_structure	classical	established	composition error, part-to-whole fallacy	Inferring that the whole has a property because its parts do. Valid for some properties (weight), fallacious for many others (visibility, efficiency, moral standing). From Aristotle's Sophistical Refutations.	2
Fallacy of Division division_fallacy Aliases division error, whole-to-part fallacy Distinguishing Features Some properties distribute from whole to parts (spatial location), others do not (value, quality). The political version frequently involves inferring individual properties from aggregate statistics. Distinguishes From composition_fallacyhasty_generalisation Common Co-occurrences composition_fallacyhasty_generalisationcherry_picking Crossover Debate Terminology None Examples 'The UK's GDP is among the world's highest; therefore individual citizens are not in poverty.' National aggregate does not distribute to individual circumstances. Source: UK poverty/inequality debate Issue: wealth_tax	formal_fallacy	formal_structure	classical	established	division error, whole-to-part fallacy	Inferring that the parts have a property because the whole does. The mirror of composition_fallacy. 'The UK is one of the world's richest nations; therefore every person in the UK is wealthy.' From Aristotle's Sophistical Refutations.	1
Fallacy of Figure of Speech figure_of_speech_fallacy Aliases grammatical form fallacy, linguistic form fallacy, schema tēs lexeōs Distinguishing Features Produces reification of abstractions ('the market has spoken', 'Britain is full') by treating collective or abstract nouns as unified agents with properties only individuals can have. Distinguishes From equivocationamphiboly Common Co-occurrences equivocationframing Crossover Debate Terminology None Examples 'The market has spoken.' Treating the aggregate outcome of millions of transactions as a singular communicative act. Source: Economic policy discourse Issue: wealth_tax 'Britain is full.' Treating a political entity as a container with a determinate capacity. Source: UK immigration debate Issue: immigration	formal_fallacy	formal_structure	classical	established	grammatical form fallacy, linguistic form fallacy, schema tēs lexeōs	Treating grammatical or linguistic form as if it reflects logical or ontological form - inferring something about reality from the structure of language used to describe it. From Aristotle's Sophistical Refutations. The basis for many category errors in political rhetoric.	2
Secundum Quid secundum_quid Aliases ignoring qualifications, hasty generalisation converse, dicto simpliciter ad dictum secundum quid Distinguishing Features Distinct from hasty_generalisation: secundum quid involves ignoring known qualifications to a principle, not merely generalising from too few cases. Distinguishes From hasty_generalisationaccident_fallacycherry_picking Common Co-occurrences hasty_generalisationcherry_pickingmalinformation Crossover Debate Terminology None Examples 'Wealth taxes have failed - look at France, Sweden, and Germany.' Without noting those implementations had specific design flaws not shared by all proposals. Source: UK wealth tax debate Issue: wealth_tax	non-engagement	formal_structure	classical	established	ignoring qualifications, hasty generalisation converse, dicto simpliciter ad dictum secundum quid	Ignoring relevant qualifications or exceptions when applying a general rule - making a universal claim from instances that are not fully representative, or failing to hedge a generalisation appropriately. The converse of accident_fallacy: accident misapplies a rule to an exception; secundum quid ignores known qualifications to over-generalise.	1
Many Questions many_questions Aliases plurium interrogationum, complex question fallacy, bundled question Distinguishing Features Exploits the social expectation of responsiveness: declining to answer appears evasive, but answering accepts all embedded claims. The defence is to unbundle: 'That is several questions. Let me take them separately.' Distinguishes From loaded_questionbegging_the_questionsealioning Common Co-occurrences loaded_questionsealioninggish_gallop Crossover Debate Terminology None Examples 'Do you support a wealth tax, open borders, and abolishing the monarchy?' - three questions bundled to force a single response. Source: UK political debate, illustrative Issue: wealth_tax 'Have you stopped beating your wife?' - answering either yes or no accepts the presupposed prior conduct. Source: Classical logic example Issue: epistemic quality	non-engagement	formal_structure	both	established	plurium interrogationum, complex question fallacy, bundled question	Bundling multiple distinct questions into one, forcing the respondent to answer them all simultaneously or appear to accept all their presuppositions. From Aristotle's Sophistical Refutations. Distinct from loaded_question: loaded_question embeds a false presupposition in a single question; many_questions bundles multiple separate issues.	2
Motivational Delegitimisation motivational_delegitimisation Aliases psychologising dissent, motive attribution, envy attribution, ad passionem Distinguishing Features Distinct from bulverism, which first assumes the position is wrong and then explains the psychology - motivational delegitimisation need not assume wrongness in advance; it forecloses engagement by contaminating intent so the position never needs to be examined. Distinct from ad_hominem, which attacks character or credibility more broadly. Distinct from attribution_of_intent, which imputes a specific strategic purpose to an action. The move here is specifically to name a disreputable emotion or interest as the real driver of a substantive claim, making the claim feel unworthy of engagement. Distinguishes From bulverismad_hominemattribution_of_intentgenetic_fallacy Common Co-occurrences straw_manfailure_to_steelmanconcept_capturefigleaf Crossover Debate Terminology None Examples 'The only reason anyone wants a wealth tax is envy - they can't stand others being more successful.' The distributional and democratic arguments for wealth taxation are never addressed. Source: UK wealth tax discourse, 2024–2026 Issue: wealth tax 'These academics pushing back on pharmaceutical companies don't actually believe their research - they just need controversy for grant applications and career progression.' Source: Science communication / public health discourse Issue: science communication 'The people demanding content moderation reforms are just bitter that their preferred voices got suppressed. It's about power, not safety.' Source: UK/US platform regulation debate Issue: platform regulation	non-engagement	psychological_rhetoric	both	coined	psychologising dissent, motive attribution, envy attribution, ad passionem	Dismissing a position by attributing it to a morally suspect motive - envy, resentment, self-interest, ideological bias - rather than engaging with the stated reasons. The position is not addressed on its merits; instead, the arguer substitutes a psychological explanation for why the person holds it, treating the alleged motive as sufficient to disqualify the claim.	3
Proof by Example proof_by_example Aliases illustrative generalisation, proof by illustration, fallacy of the single instance, anecdotal reasoning Distinguishing Features Distinct from hasty_generalisation, which involves drawing general conclusions from too few observed cases drawn from the world. In proof by example the case may be constructed rather than observed - often with mathematical or logical precision that lends it false evidential weight. The problem is not the example itself (which may be entirely correct) but the inferential move from it to the general claim. The precision of a constructed illustration can actively mislead by making the generalisation feel empirically grounded when it is not. See the illustrative_probative_distinction entry in debate_terminology for the argumentation-theory background. Distinguishes From hasty_generalisationsampling_biasperformed_empiricismsecundum_quiddistributional_anchoring Common Co-occurrences performed_empiricismdistributional_anchoringfalse_causal_chainphantom_quantification Crossover Debate Terminology None Examples 'If you've made £100 in gains and pay 25% CGT, you need a 33% return on your next investment just to break even - therefore capital gains tax misallocates capital across the whole economy.' The arithmetic is correct; the generalisation from a single constructed case to an economy-wide mechanism is not supported by it. Source: UK wealth tax discourse, Jacob Rees-Mogg, 2026 Issue: wealth tax 'Here is one town where the arrival of a large migrant workforce was followed by a wage reduction for local workers. Therefore immigration depresses wages.' A single real case treated as if it settles a contested general empirical question. Source: UK immigration debate Issue: immigration 'A company I know moved operations abroad after the corporation tax rise - therefore corporation tax increases drive offshoring.' A single anecdote used to establish a general causal claim. Source: UK business and tax debate Issue: corporation tax	formal_fallacy	evidence_quality	classical	established	illustrative generalisation, proof by illustration, fallacy of the single instance, anecdotal reasoning	Treating a single constructed or selected example as if it constitutes evidence for a general claim. The example illustrates what a phenomenon would look like if it were true, but is then used as if it demonstrated that the phenomenon holds in the general case. The critical distinction is between illustrative examples - which show how something works in principle - and probative examples - which constitute evidence that something actually obtains. This fallacy conflates the two functions.	3
Distributional Anchoring distributional_anchoring Aliases standpoint sampling, perspective anchoring, class-unmarked example Distinguishing Features Distinct from sampling_bias, which involves selecting unrepresentative observed data points from the world. Distributional anchoring is specifically about the constructed standpoint of illustrative examples - who the implied actor is and where they sit in the distribution - rather than data selection. The reader is not told 'this is how it looks from the top of the distribution'; the example is presented without standpoint disclosure. Particularly common in fiscal and economic policy discourse, where examples drawn from asset-rich or high-income positions are used to make arguments about general economic mechanisms. Often co-occurs with proof_by_example: the example is both constructed and anchored to an unrepresentative position. Distinguishes From sampling_biashasty_generalisationproof_by_exampleecological_fallacy Common Co-occurrences proof_by_exampleperformed_empiricismstraw_mannormative_laundering Crossover Debate Terminology None Examples 'If someone has a house worth £20 million and faces a 1% annual wealth tax, they owe £200,000 in cash on an illiquid asset - therefore wealth taxes are structurally unworkable.' The example is anchored to the ultra-high-net-worth end; the vast majority of any plausible wealth tax base would not face this liquidity problem. Source: UK wealth tax discourse, 2026 Issue: wealth tax 'If I'm earning £250,000 and the marginal rate goes to 65%, I lose nearly two-thirds of every additional pound I earn - therefore high marginal rates kill the incentive to work harder.' Anchored to the very top of the income distribution; median earners face no such rate. Source: UK income tax debate Issue: income tax 'A capital gains event triggers a 24% tax liability before the investor can reallocate - therefore CGT freezes capital and harms new business formation.' Constructed from the perspective of a repeat high-gain investor; typical small-scale capital events have very different dynamics. Source: UK investment and growth debate Issue: capital gains tax	manipulation	evidence_quality	modern	coined	standpoint sampling, perspective anchoring, class-unmarked example	Anchoring all illustrative examples at one end of a relevant distribution - typically the high-wealth, high-income, or otherwise exceptional end - while presenting those examples as representative of general or universal conditions. The standpoint from which the examples are constructed is not disclosed, making a partial view appear to be a view from nowhere.	3
Normative Laundering normative_laundering Aliases empirical-to-normative slide, value smuggling, fact-value laundering, is-ought laundering Distinguishing Features Distinct from mechanistic_laundering, which runs between two empirical claims - using a plausible mechanism to establish a factual conclusion without adequate evidence. Normative laundering runs from empirical or mechanistic claims to a normative or evaluative conclusion. The suppressed premise is always a value judgement: about which purposes are legitimate, which trade-offs are acceptable, or whose interests count. Often identifiable by asking: what normative premise would have to be true for this empirical observation to support this evaluative conclusion? Philosophically, this is an instance of the is-ought gap (Hume's guillotine) used as a rhetorical strategy rather than a logical error made in good faith. Distinguishes From mechanistic_launderingbegging_the_questionpersuasive_definitionfalse_causal_chain Common Co-occurrences performed_empiricismconcept_capturefigleafdistributional_anchoring Crossover Debate Terminology None Examples 'Capital gains tax reduces allocative efficiency - therefore redistribution via taxation is illegitimate.' Suppressed normative premise: allocative efficiency is the only criterion by which tax design should be judged. Source: UK wealth tax discourse, 2026 Issue: wealth tax 'This environmental regulation imposes £400m in compliance costs - therefore the regulation is bad policy.' Suppressed normative premise: compliance costs always outweigh regulatory benefits, or economic cost is the only relevant metric. Source: UK regulatory debate Issue: environmental regulation 'Affirmative action sometimes produces candidates who underperform the predicted merit ranking - therefore affirmative action is unjust.' Suppressed normative premise: only individual meritocratic allocation of outcomes is just; structural inequality has no legitimate claim on corrective policy. Source: Equality and diversity policy debate Issue: equality policy	manipulation	semantic_manipulation	modern	coined	empirical-to-normative slide, value smuggling, fact-value laundering, is-ought laundering	Using empirical or mechanistic claims to smuggle in a normative conclusion without making the normative step explicit or defending it. The argument presents itself as purely factual analysis, but the conclusion is a value judgement that requires a suppressed normative premise. By embedding the normative conclusion within a chain of empirical reasoning, the arguer avoids having to defend the value position directly.	3
