{{Short description|none}} <!-- "none" is a legitimate description when the title is already adequate; see [[WP:SDNONE]] -->
A [[fallacy]] is the use of [[Validity (logic)|invalid]] or otherwise faulty reasoning in the construction of an argument. All forms of human communication can contain fallacies.

Because of their variety, fallacies are challenging to classify. They can be classified by their structure ([[formal fallacies]]) or content ([[informal fallacies]]). Informal fallacies, the larger group, may then be subdivided into categories such as improper presumption, faulty generalization, error in assigning causation, and relevance, among others.

The use of fallacies is common when the speaker's goal of achieving common agreement is more important to them than utilizing sound reasoning. When fallacies are used, the premise should be recognized as not well-grounded, the conclusion as unproven (but not necessarily false), and the argument as unsound.<ref>{{cite book |last=Hornby |first=A.

== Formal fallacies ==
{{Main|Formal fallacy}}

A formal fallacy is an error in the [[argument form|argument's form]].{{sfn|Bunnin|Yu|2004|loc=[http://www.blackwellreference.com/public/tocnode?id=g9781405106795_chunk_g97814051067957_ss1-95 "formal fallacy"]}} All formal fallacies are types of {{lang|la|[[Non sequitur (logic)|non sequitur]]}}.
* [[Appeal to probability]] – taking something for granted because it would probably be the case (or might possibly be the case).<ref>{{cite web|title=Appeal to possibility |last=Bennett |first=Bo |work=Logically Fallacious |access-date=2023-03-17|url=https://www.logicallyfallacious.com/logicalfallacies/Appeal-to-Possibility}}</ref><ref>{{cite book|last=Carrier |first=Richard |title=Proving History: Bayes's Theorem and the Quest for the Historical Jesus |publisher=Prometheus Books |date=2012 |pages=26–29 |isbn=9781616145590}}</ref>
* [[Argument from fallacy]] (also known as the fallacy fallacy) – the assumption that, if a particular ''argument'' for a "conclusion" is fallacious, then the ''conclusion'' by itself is false.{{sfn|Curtis|loc=[http://www.fallacyfiles.org/fallfall.html "Fallacy Fallacy"]}}
* [[Base rate fallacy]] – making a probability judgment based on [[conditional probability|conditional probabilities]], without taking into account the effect of [[prior probability|prior probabilities]].<ref>{{cite web |url=http://www.alleydog.com/glossary/definition.php?term=Base%20Rate%20Fallacy |title=Base Rate Fallacy |access-date=2011-02-01 |work=Psychology Glossary |publisher=AlleyDog.com |archive-date=2011-07-07 |archive-url=https://web.archive.org/web/20110707113446/http://www.alleydog.com/glossary/definition.php?term=Base%20Rate%20Fallacy |url-status=live}}</ref>
* [[Conjunction fallacy]] – the assumption that an outcome simultaneously satisfying multiple conditions is more probable than an outcome satisfying a single one of them.<ref>{{cite web |url=http://changingminds.org/explanations/theories/conjunction_fallacy.htm |title=Conjunction Fallacy |access-date=2011-02-01 |work=ChangingMinds.org |last=Straker |first=David |archive-date=2011-08-13 |archive-url=https://web.archive.org/web/20110813092704/http://changingminds.org/explanations/theories/conjunction_fallacy.htm |url-status=live}}</ref>
* [[Non sequitur (fallacy)|{{lang|la|nocat=y|Non sequitur}} fallacy]] – where the conclusion does not logically follow the premise.<ref>{{Cite web|last=Bennett|first=Bo|title=Non Sequitur|url=https://www.logicallyfallacious.com/logicalfallacies/Non-Sequitur|url-status=live|website=logicallyfallacious|access-date=2021-04-23|archive-date=2022-07-01|archive-url=https://web.archive.org/web/20220701051548/https://www.logicallyfallacious.com/uy/loading.html}}</ref>
* [[Masked-man fallacy]] (illicit substitution of identicals) – the substitution of identical designators in a true statement can lead to a false one.{{sfn|Curtis|loc=[http://www.fallacyfiles.org/illisubs.html "The Masked Man Fallacy"]}}

=== Propositional fallacies ===
A propositional fallacy is an error that concerns compound propositions. For a compound proposition to be true, the truth values of its constituent parts must satisfy the relevant logical connectives that occur in it (most commonly: [and], [or], [not], [only if], [if and only if]). The following fallacies involve relations whose truth values are not guaranteed and therefore not guaranteed to yield true conclusions.
<br />Types of [[Propositional calculus|propositional]] fallacies:
* [[Affirming a disjunct]] – concluding that one disjunct of a [[logical disjunction]] must be false because the other disjunct is true; ''A or B; A, therefore not B''.{{sfn|Wilson|1999|p=316}}
* [[Affirming the consequent]] – the [[antecedent (logic)|antecedent]] in an [[indicative conditional]] is claimed to be true because the [[consequent]] is true; ''if A, then B; B, therefore A''.{{sfn|Wilson|1999|p=316}}
* [[Denying the antecedent]] – the [[consequent]] in an [[indicative conditional]] is claimed to be false because the [[antecedent (logic)|antecedent]] is false; ''if A, then B; not A, therefore not B''.{{sfn|Wilson|1999|p=316}}

=== Quantification fallacies ===
A quantification fallacy is an error in logic where the quantifiers of the premises are in contradiction to the quantifier of the conclusion.
<br /> Types of [[Quantification (logic)|quantification]] fallacies:
* [[Existential fallacy]] – an argument that has a universal premise and a particular conclusion.{{sfn|Wilson|1999|p=317}}

=== Formal syllogistic fallacies ===
[[Syllogistic fallacy|Syllogistic fallacies]] – logical fallacies that occur in [[syllogisms]].
* [[Affirmative conclusion from a negative premise]] (illicit negative) – a categorical [[syllogism]] has a positive conclusion, but at least one negative premise.{{sfn|Wilson|1999|p=317}}
* [[Fallacy of exclusive premises]] – a categorical syllogism that is invalid because both of its premises are negative.{{sfn|Wilson|1999|p=317}}
* [[Fallacy of four terms]] (''quaternio terminorum'') – a categorical syllogism that has four terms.{{sfn|Pirie|2006|pp=133–136}}
* [[Illicit major]] – a categorical syllogism that is invalid because its major term is not [[distribution of terms|distributed]] in the major premise but distributed in the conclusion.{{sfn|Wilson|1999|p=317}}
* [[Illicit minor]] – a categorical syllogism that is invalid because its minor term is not distributed in the minor premise but distributed in the conclusion.{{sfn|Wilson|1999|p=317}}
* [[Negative conclusion from affirmative premises]] (illicit affirmative) – a categorical syllogism has a negative conclusion but affirmative premises.{{sfn|Wilson|1999|p=317}}
* [[Fallacy of the undistributed middle]] – the middle term in a categorical syllogism is not distributed.{{sfn|Wilson|1999|pp=316–317}}
* [[Modal fallacy]] – confusing necessity with sufficiency. A condition X is necessary for Y if X is required for even the possibility of Y. X does not bring about Y by itself, but if there is no X, there will be no Y. For example, oxygen is necessary for fire. But one cannot assume that everywhere there is oxygen, there is fire. A condition X is sufficient for Y if X, by itself, is enough to bring about Y. For example, riding the bus is a sufficient mode of transportation to get to work. But there are other modes of transportation – car, taxi, bicycle, walking – that can be used.
* [[Modal scope fallacy]] – a degree of unwarranted necessity is placed in the conclusion.

== Informal fallacies ==
{{Main|Informal fallacy}}
Informal fallacies – arguments that are logically unsound for lack of well-grounded premises.{{sfn|Bunnin|Yu|2004|loc=[http://www.blackwellreference.com/public/tocnode?id=g9781405106795_chunk_g978140510679510_ss1-120 "informal fallacy"]}}

* [[Argument from incredulity]] – when someone can't imagine something to be true, and therefore deems it false, or conversely, holds that it must be true because they can't see how it could be false.<ref>{{Cite web |title=The Argument from Incredulity: What It Is and How to Respond to It – Effectiviology |url=https://effectiviology.com/argument-from-incredulity/ |access-date=2024-11-01 |language=en-US}}</ref>
* [[Argument to moderation]] (false compromise, middle ground, fallacy of the mean, {{lang|la|argumentum ad temperantiam}}) – assuming that a compromise between two positions is always correct.{{sfn|Damer|2009|p=150}}
* [[Continuum fallacy]] (fallacy of the beard, line-drawing fallacy, sorites fallacy, fallacy of the heap, bald man fallacy, decision-point fallacy) – improperly rejecting a claim for being imprecise.{{sfn|Dowden|2010|loc=[http://www.iep.utm.edu/fallacy/#Line-Drawing "Line-Drawing"]}}
* [[Correlative-based fallacies]]
** [[Suppressed correlative]] – a correlative is redefined so that one alternative is made impossible (e.g., "I'm not fat because I'm thinner than John.").<ref>{{cite book |title=Ethical Theory: An Anthology |chapter=Psychological Egoism |page=193 |first=Joel |last=Feinberg |editor-first=Russ |editor-last=Shafer-Landau |publisher=Wiley-Blackwell |series=Blackwell Philosophy Anthologies |date=2007 |isbn=9781405133203 |chapter-url=https://books.google.com/books?id=By9nCkAvS6EC&pg=PT211 |access-date=2016-10-04 |archive-date=2016-11-21 |archive-url=https://web.archive.org/web/20161121111523/https://books.google.com/books?id=By9nCkAvS6EC&pg=PT211 |url-status=live}}</ref>
* [[Definist fallacy]] – defining a term used in an argument in a biased manner (e.g., using "loaded terms"). The person making the argument expects that the listener will accept the provided definition, making the argument difficult to refute.<ref>{{cite journal |title=The Naturalistic Fallacy |first=W. K. |last=Frankena |journal=Mind |volume=48 |date=October 1939 |pages=464–477 |publisher=Oxford University Press |jstor=2250706 |issue=192|doi=10.1093/mind/XLVIII.192.464}}</ref>
* [[Divine fallacy]] (argument from incredulity) – arguing that, because something is so phenomenal or amazing, it must be the result of superior, divine, alien or paranormal agency.<ref>{{cite web|last=Carroll|first=Robert T.|author-link=Robert Todd Carroll|work=[[The Skeptic's Dictionary]]|url=http://skepdic.com/dvinefal.html|title=divine fallacy (argument from incredulity)|access-date=5 April 2013|archive-date=10 April 2013|archive-url=https://web.archive.org/web/20130410153028/http://www.skepdic.com/dvinefal.html|url-status=live}}</ref>
* [[Double counting (fallacy)|Double counting]] – counting events or occurrences more than once in probabilistic reasoning, which leads to the sum of the probabilities of all cases exceeding [[unity (number)|unity]].
* [[Equivocation]] – using a term with more than one meaning in a statement without specifying which meaning is intended.{{sfn|Damer|2009|p=121}}
** [[Ambiguous middle term]] – using a [[middle term]] with multiple meanings.{{sfn|Copi|Cohen|1990|pp=[https://archive.org/details/introductiontol00copi/page/206 206–207]}}
** Definitional retreat – changing the meaning of a word when an objection is raised.{{Sfn|Pirie|2006|p=46}} Often paired with moving the goalposts (see below), as when an argument is challenged using a common definition of a term in the argument, and the arguer presents a different definition of the term and thereby demands different evidence to debunk the argument.
** {{anchor|Motte-and-bailey}}[[Motte-and-bailey fallacy]] – conflating two positions with similar properties, one modest and easy to defend (the "motte") and one more controversial (the "bailey").<ref>{{cite web |last1=Zabel |first1=Joseph |title=The Motte and the Bailey: A rhetorical strategy to know |url=https://heterodoxacademy.org/the-motte-and-the-bailey-a-rhetorical-strategy-to-know/ |website=heterodoxacademy.org |date=9 August 2017 |access-date=30 January 2020 |archive-date=4 February 2020 |archive-url=https://web.archive.org/web/20200204013358/https://heterodoxacademy.org/the-motte-and-the-bailey-a-rhetorical-strategy-to-know/ |url-status=live}}</ref> The arguer first states the controversial position, but when challenged, states that they are advancing the modest position.<ref name="mott-and-bailey">{{cite journal |last=Shackel |first=Nicholas |title=The Vacuity of Postmodernist Methodology |journal=[[Metaphilosophy (journal)|Metaphilosophy]] |date=2005 |volume=36 |issue=3 |pages=295–320 |doi=10.1111/j.1467-9973.2005.00370.x |url=http://orca.cf.ac.uk/50091/1/shackel%20The%20Vacuity%20of%20Postmodernist%20Methodology%20final%20archivable.pdf |quote=For my purposes the desirable but only lightly defensible territory of the Motte and Bailey castle, that is to say, the Bailey, represents a philosophical doctrine or position with similar properties: desirable to its proponent but only lightly defensible.

** [[Accent (fallacy)|Fallacy of accent]] – changing the meaning of a statement by not specifying on which word emphasis falls.
** [[Persuasive definition]] – purporting to use the "true" or "commonly accepted" meaning of a term while, in reality, using an uncommon or altered definition.
** {{crossreference|printworthy=y|(cf. the [[#If-by-whiskey|if-by-whiskey]] fallacy)}}
* [[Ecological fallacy]] – inferring about the nature of an entity based solely upon aggregate statistics collected for the group to which that entity belongs.{{sfn|Fischer|1970|pp=[https://archive.org/details/historiansfallac0000fisc/page/119 119–120]}}
* [[Etymological fallacy]] – assuming that the original or historical meaning of a word or phrase is necessarily similar to its actual present-day usage.{{sfn|Gula|2002|p=70}}
* [[Fallacy of composition]] – assuming that something true of part of a whole must also be true of the whole.{{sfn|Pirie|2006|p=31}}
* [[Fallacy of division]] – assuming that something true of a composite thing must also be true of all or some of its parts.{{sfn|Pirie|2006|p=53}}
* [[False attribution]] – appealing to an irrelevant, unqualified, unidentified, biased or fabricated source in support of an argument.
** [[Fallacy of quoting out of context]] (contextotomy, contextomy; quotation mining) – selective excerpting of words from their original context to distort the intended meaning.{{sfn|Gula|2002|p=97}}
* [[False authority]] (single authority) – using an expert of dubious credentials or using only one opinion to promote a product or idea. Related to the [[appeal to authority]].
* [[False dilemma]] (false dichotomy, fallacy of bifurcation, black-or-white fallacy) – two alternative statements are given as the only possible options when, in reality, there are more.<ref>{{cite web |url=http://www.nizkor.org/features/fallacies/false-dilemma.html |title=Fallacy – False Dilemma |access-date=2011-02-01 |publisher=The Nizkor Project |work=Nizkor |archive-url=https://web.archive.org/web/20150923145959/http://www.nizkor.org/features/fallacies/false-dilemma.html |archive-date=2015-09-23 |url-status=dead}}</ref>
* [[False equivalence]] – describing two or more statements as virtually equal when they are not.
* [[Feedback fallacy]] – believing in the objectivity of an evaluation to be used as the basis for improvement without verifying that the source of the evaluation is a disinterested party.<ref>{{cite magazine |url=https://hbr.org/2019/03/the-feedback-fallacy |title=The Feedback Fallacy |author1=Marcus Buckingham |author2=Ashley Goodall |issue=March–April 2019 |magazine=[[Harvard Business Review]] |access-date=2019-03-11 |archive-date=2019-05-27 |archive-url=https://web.archive.org/web/20190527230154/https://hbr.org/2019/03/the-feedback-fallacy |url-status=live}}</ref>
* [[Historian's fallacy]] – assuming that decision-makers of the past had identical information as those subsequently analyzing the decision.{{sfn|Fischer|1970|pp=[https://archive.org/details/historiansfallac0000fisc/page/209 209–213]}} This is not to be confused with [[presentism (historical analysis)|presentism]], in which present-day ideas and perspectives are anachronistically projected into the past.
* [[Historical fallacy]] – believing that certain results occurred only because a specific process was performed, though said process may actually be unrelated to the results.<ref>"The Reflex Arc Concept in Psychology", John Dewey, ''The Psychological Review'', Vol. III. No. 4. July 1896. p. 367</ref>
** [[Baconian fallacy]] – supposing that historians can obtain the "whole truth" via induction from individual pieces of historical evidence. The "whole truth" is defined as learning "something about everything", "everything about something", or "everything about everything". In reality, a historian "can only hope to know something about something".{{sfn|Fischer|1970|pp=[https://archive.org/details/historiansfallac0000fisc/page/4 4–8]}}
* [[Homunculus fallacy]] – using a "middle-man" for explanation; this sometimes leads to regressive middle-men. It explains a concept in terms of the concept itself without explaining its real nature (e.g.: explaining thought as something produced by a little thinker – a [[homunculus]] – inside the head simply identifies an intermediary actor and does not explain the product or process of thinking).{{sfn|Bunnin|Yu|2004|loc=[https://web.archive.org/web/20120113200604/http://www.blackwellreference.com/public/tocnode?query=homunculus&widen=1&result_number=1&book_id=g9781405106795_9781405106795&from=search&fuzzy=0&type=std&id=g9781405106795_chunk_g97814051067959_ss1-77&slop=1 "Homunculus"]}}

* {{anchor|If-by-whiskey}}[[If-by-whiskey]] – an argument that supports both sides of an issue by using terms that are emotionally sensitive and ambiguous.
* [[Incomplete comparison]] – insufficient information is provided to make a complete comparison.
* [[Intentional Fallacy|Intentionality fallacy]] – the insistence that the ultimate meaning of an expression must be consistent with the intention of the person from whom the communication originated (e.g. a work of fiction that is widely received as a blatant allegory must necessarily not be regarded as such if the author intended it not to be so).<ref>{{cite journal |journal=Sewanee Review |volume=54 |date=1946 |pages=468–488 |first1=William K. |last1=Wimsatt |author1-link=William K.

* [[McNamara fallacy]] (quantitative fallacy) – making an argument using only quantitative observations (measurements, statistical or numerical values) and discounting subjective information that focuses on quality (traits, features, or relationships).
* [[Mind projection fallacy]] – assuming that a statement about an object describes an inherent property of the object, rather than a personal perception.
* [[Moralistic fallacy]] – inferring factual conclusions from evaluative premises in violation of [[fact–value distinction]] (e.g.: inferring ''is'' from ''ought''). Moralistic fallacy is the inverse of [[naturalistic fallacy]].
* [[Moving the goalposts]] (raising the bar) – argument in which evidence presented in response to a specific claim is dismissed and some other (often greater) evidence is demanded.
* [[Nirvana fallacy]] (perfect-solution fallacy) – solutions to problems are rejected because they are not perfect.
* [[Package-deal fallacy|Package deal]] – treating essentially dissimilar concepts as though they were essentially similar.
* [[Proof by assertion]] – a proposition is repeatedly restated regardless of contradiction; sometimes confused with [[argument from repetition]] ({{lang|la|argumentum ad infinitum}}, {{lang|la|argumentum ad nauseam}}).
* [[Prosecutor's fallacy]] – a low probability of false matches does not mean a low probability of {{em|some}} false match being found.<ref name="TS">{{cite journal |last1=Thompson |first1=William C. |last2=Schumann |first2=Edward L. |year=1987 |title=Interpretation of Statistical Evidence in Criminal Trials: The Prosecutor's Fallacy and the Defense Attorney's Fallacy |journal=Law and Human Behavior |volume=11 |issue=3 |pages=167–187 |doi=10.1007/BF01044641 |jstor=1393631 |s2cid=147472915}}</ref><ref>{{Cite journal |last=Suss |first=Richard A. |date=October 4, 2023 |title=The Prosecutor's Fallacy Framed as a Sample Space Substitution |journal=OSF Preprints |language=en |doi=10.31219/osf.io/cs248}}</ref>
* [[Proving too much]] – an argument that results in an overly generalized conclusion (e.g.: arguing that drinking alcohol is bad because in some instances it has led to spousal or child abuse).
* [[Psychologist's fallacy]] – an observer presupposes the objectivity of their own perspective when analyzing a behavioral event.
* [[Direct reference theory|Referential fallacy]]<ref>Semiotics Glossary R, [http://www.cs.oswego.edu/~blue/xhx/books/semiotics/glossaryR/section81/main.html ''Referential fallacy or illusion''] {{Webarchive|url=https://web.archive.org/web/20180726060351/http://www.cs.oswego.edu/~blue/xhx/books/semiotics/glossaryR/section81/main.html |date=2018-07-26}}</ref> – assuming that all words refer to existing things and that the meaning of words reside within the things they refer to, as opposed to words possibly referring to no real object (e.g.: Pegasus) or that the meaning comes from how they are used (e.g.: "nobody" was in the room).
* [[Reification (fallacy)|Reification]] (concretism, hypostatization, or the fallacy of misplaced concreteness) – treating an abstract belief or hypothetical construct as if it were a concrete, real event or physical entity (e.g.: saying that evolution selects which traits are passed on to future generations; evolution is not a conscious entity with agency).
* [[Retrospective determinism]] – believing that, because an event has occurred under some circumstance, the circumstance must have made the event inevitable (e.g.: because someone won the lottery while wearing their lucky socks, wearing those socks made winning the lottery inevitable).
* [[Slippery slope]] (thin edge of the wedge, [[camel's nose]]) – asserting that a proposed, relatively small, first action will inevitably lead to a chain of related events resulting in a significant and negative event and, therefore, should not be permitted.{{sfn|Walton|2008|p=315}}
* [[Special pleading]] – the arguer attempts to cite something as an exemption to a generally accepted rule or principle without justifying the exemption (e.g.: an orphaned defendant who murdered their parents asking for leniency).

=== Improper premise ===
* [[Begging the question]] ({{lang|la|petitio principii}}) – using the conclusion of the argument in support of itself in a premise (e.g.: saying that smoking cigarettes is deadly because cigarettes can kill you; something that kills is deadly).<ref>{{cite web|url=http://www.nizkor.org/features/fallacies/begging-the-question.html|title=Fallacy: Begging the Question|work=nizkor.org|access-date=2016-02-24|archive-url=https://web.archive.org/web/20190310182956/http://www.nizkor.org/features/fallacies/begging-the-question.html|archive-date=2019-03-10|url-status=dead}}</ref><ref>{{cite web|url=http://www.txstate.edu/philosophy/resources/fallacy-definitions/Begging-the-Question.html|title=Begging the Question|work=txstate.edu|access-date=2016-02-24|archive-date=2015-09-28|archive-url=https://web.archive.org/web/20150928002901/http://www.txstate.edu/philosophy/resources/fallacy-definitions/Begging-the-Question.html|url-status=live}}</ref>
** Loaded label – while not inherently fallacious, the use of evocative terms to support a conclusion is a type of [[begging the question]] fallacy. When fallaciously used, the term's connotations are relied on to sway the argument towards a particular conclusion. For example, in an organic foods advertisement that says "Organic foods are safe and healthy foods grown without any pesticides, herbicides, or other unhealthy additives", the terms "safe" and "healthy" are used to fallaciously imply that non-organic foods are neither safe nor healthy.<ref>{{cite book |last1=Ramage |first1=John D. |url=https://books.google.com/books?id=T-HEjwEACAAJ |title=Writing Arguments: A Rhetoric with Readings, Concise Edition |last2=Bean |first2=John C. |last3=Johnson |first3=June |date=2016 |publisher=Pearson Education |isbn=9780134586496 |edition=MLA Update |page=275 |access-date=2018-04-03 |archive-url=https://web.archive.org/web/20200220033132/https://books.google.com/books?id=T-HEjwEACAAJ |archive-date=2020-02-20 |url-status=live}}</ref>
* [[Circular reasoning]] ({{lang|la|circulus in demonstrando}}) – the reasoner begins with what they are trying to end up with (e.g.: all bachelors are unmarried males).
* [[Loaded question|Fallacy of many questions]] (complex question, fallacy of presuppositions, loaded question, {{lang|la|plurium interrogationum}}) – someone asks a question that presupposes something that has not been proven or accepted by all the people involved. This fallacy is often used rhetorically so that the question limits direct replies to those that serve the questioner's agenda. (E.g., "Have you or have you not stopped beating your wife?".)

=== Faulty generalizations ===
[[Faulty generalization]] – reaching a conclusion from weak premises.
* [[Accident (fallacy)|Accident]] – an exception to a generalization is ignored.{{sfn|Pirie|2006|p=5}}
** [[No true Scotsman]] (aka appeal to purity) – makes a generalization true by changing the generalization to exclude a counterexample.{{sfn|Flew|1984|loc="No-true-Scotsman move"}}
* [[Cherry picking (fallacy)|Cherry picking]] (suppressed evidence, incomplete evidence, argument by half-truth, fallacy of exclusion, card stacking, slanting) – using individual cases or data that confirm a particular position, while ignoring related cases or data that may contradict that position.{{sfn|Hurley|2007|p=155}}<ref>{{Cite web|last=Bennett|first=Bo|title=Cherry Picking|url=https://www.logicallyfallacious.com/logicalfallacies/Cherry-Picking|url-status=live|access-date=|website=logicallyfallacious|archive-date=2022-07-01|archive-url=https://web.archive.org/web/20220701051554/https://www.logicallyfallacious.com/uy/loading.html}}</ref>
** [[Nut-picking]] (suppressed evidence, incomplete evidence) – using individual cases or data that falsify a particular position, while ignoring related cases or data that may support that position.
** [[Survivorship bias]] – a small number of successes of a given process are actively promoted while completely ignoring a large number of failures.
* [[False analogy]] – an argument by analogy in which the analogy is poorly suited.{{sfn|Damer|2009|p=151}}
* [[Hasty generalization]] (fallacy of insufficient statistics, fallacy of insufficient sample, fallacy of the lonely fact, hasty induction, ''secundum quid'', converse accident, [[jumping to conclusions]]) – basing a broad conclusion on a small or unrepresentative sample.{{sfn|Hurley|2007|p=134}}
* [[Argument from anecdote]] – a fallacy where [[anecdotal evidence]] is presented as an argument; without any other contributory evidence or reasoning.
* [[Inductive fallacy]] – a more general name for a class of fallacies, including hasty generalization and its relatives. A fallacy of induction happens when a conclusion is drawn from premises that only lightly support it.
* [[Misleading vividness]] – involves describing an occurrence in vivid detail, even if it is an exceptional occurrence, to convince someone that it is more important; this also relies on the [[appeal to emotion]] fallacy.
* [[Overwhelming exception]] – an accurate generalization that comes with qualifications that eliminate so many cases that what remains is much less impressive than the initial statement might have led one to assume.{{sfn|Fischer|1970|p=[https://archive.org/details/historiansfallac0000fisc/page/127 127]}}
* [[Thought-terminating cliché]] – a commonly used phrase, sometimes passing as folk wisdom, used to quell [[cognitive dissonance]], conceal lack of forethought, move on to other topics, etc. – but in any case, to end the debate with a cliché rather than a point.

=== Questionable cause ===
[[Questionable cause]] is a general type of error with many variants. Its primary basis is the confusion of association with causation, either by inappropriately deducing (or rejecting) causation or a broader failure to properly investigate the cause of an observed effect.
* {{lang|la|[[Cum hoc ergo propter hoc]]}} (Latin for 'with this, therefore because of this'; correlation implies causation; faulty cause/effect, coincidental correlation, correlation without causation) – a faulty assumption that, because there is a correlation between two variables, one caused the other.{{sfn|Pirie|2006|p=41}}
** {{lang|la|[[Post hoc ergo propter hoc]]}} (Latin for 'after this, therefore because of this'; temporal sequence implies causation) – X happened, then Y happened; therefore X caused Y.{{sfn|Damer|2009|p=180}}
** [[Wrong direction]] (reverse causation) – cause and effect are reversed. The cause is said to be the effect and vice versa.{{sfn|Gula|2002|p=135}} The consequence of the phenomenon is claimed to be its root cause.
** [[Ignoring a common cause]]
* [[Fallacy of the single cause]] (causal oversimplification{{sfn|Damer|2009|p=178}}) – it is assumed that there is one, simple cause of an outcome when in reality it may have been caused by a number of only jointly sufficient causes.<!-- Damer describes this in more general terms. -->
* [[Furtive fallacy]] – outcomes are asserted to have been caused by the malfeasance of decision makers.
* [[Magical thinking]] – fallacious attribution of causal relationships between actions and events. In [[anthropology]], it refers primarily to cultural beliefs that ritual, prayer, sacrifice, and taboos will produce specific supernatural consequences. In [[psychology]], it refers to an irrational belief that thoughts by themselves can affect the world or that thinking something corresponds with doing it.

==== Statistical fallacies ====

* The [[observational interpretation fallacy]] occures when associations identified in observational studies are misinterpreted as causal relationships. 
* [[Regression fallacy]] – ascribes cause where none exists. The flaw is failing to account for natural fluctuations. It is frequently a special kind of ''post hoc'' fallacy.
* [[Gambler's fallacy]] – the incorrect belief that separate, independent events can affect the likelihood of another random event. If a fair coin lands on heads 10 times in a row, the belief that it is "due to the number of times it had previously landed on tails" is incorrect.{{sfn|Damer|2009|p=186}}
** [[Inverse gambler's fallacy]] – the inverse of the gambler's fallacy. It is the incorrect belief that on the basis of an unlikely outcome, the process must have happened many times before.
* [[p-hacking]] – belief in the significance of a result, not realizing that multiple comparisons or experiments have been run and only the most significant were published.
* [[Garden of forking paths fallacy]] – incorrect belief that a single experiment can not be subject to the multiple comparisons effect.
* [[Sunk costs fallacy]] - refusal to leave a situation because you have already put large amounts of time or effort into it- for example trying to jump over a wall you physically cannot jump over because you have already spent an hour trying to jump.

=== Relevance fallacies ===
* [[Appeal to the stone]] ({{lang|la|argumentum ad lapidem}}) – dismissing a claim as absurd without demonstrating proof for its absurdity.<ref>{{cite journal|jstor=2709600|title=Johnson's Refutation of Berkeley: Kicking the Stone Again|last1=Patey|first1=Douglas Lane|journal=Journal of the History of Ideas|date=1986|volume=47|issue=1|pages=139–145|doi=10.2307/2709600}}</ref>

==== Red herring fallacies ====
A red herring fallacy, one of the main subtypes of fallacies of relevance, is an error in logic where a proposition is, or is intended to be, misleading in order to make irrelevant or false inferences. This includes any logical inference based on fake arguments, intended to replace the lack of real arguments or to replace implicitly the subject of the discussion.{{sfn|Curtis|loc=[http://www.fallacyfiles.org/redherrf.html Red Herring]}}<ref>{{cite web|url=http://www.logicalfallacies.info/relevance/red-herring/|title=Logical Fallacies|work=logicalfallacies.info|access-date=2016-02-24|archive-date=2016-02-21|archive-url=https://web.archive.org/web/20160221165603/http://www.logicalfallacies.info/relevance/red-herring/|url-status=live}}</ref>

[[Red herring]] – introducing a second argument in response to the first argument that is irrelevant and draws attention away from the original topic (e.g.: saying "If you want to complain about the dishes I leave in the sink, what about the dirty clothes you leave in the bathroom?").{{sfn|Damer|2009|p=208}} In [[jury trial]], it is known as a [[Chewbacca defense]]. In political strategy, it is called a [[dead cat strategy]]. {{crossreference|printworthy=y|See also [[ignoratio elenchi|irrelevant conclusion]].}}
* {{lang|la|[[Ad hominem]]}} – attacking the arguer instead of the argument. (Note that "{{lang|la|ad hominem}}" can also refer to the dialectical strategy of arguing on the basis of the opponent's own commitments. This type of {{lang|la|ad hominem}} is not a fallacy.)
** [[Ad hominem#Circumstantial|Circumstantial {{lang|la|nocat=y|ad hominem}}]] – stating that the arguer's personal situation or perceived benefit from advancing a conclusion means that their conclusion is wrong.<ref>{{cite web |url=http://www.nizkor.org/features/fallacies/circumstantial-ad-hominem.html |title=Circumstantial Ad Hominem |author=Nizkor |access-date=September 5, 2018 |archive-url=https://web.archive.org/web/20150713071518/http://www.nizkor.org/features/fallacies/circumstantial-ad-hominem.html |archive-date=July 13, 2015 |url-status=dead}}</ref>
** [[Poisoning the well]] – a subtype of {{lang|la|ad hominem}} presenting adverse information about a target person with the intention of discrediting everything that the target person says.{{sfn|Walton|2008|p=187}}
** [[Appeal to motive]] – dismissing an idea by questioning the motives of its proposer.
** [[Tone policing]] – focusing on emotion behind (or resulting from) a message rather than the message itself as a discrediting tactic.
** [[Ergo decedo|Traitorous critic fallacy]] ({{lang|la|ergo decedo}}, 'therefore I leave') – a critic's perceived affiliation is portrayed as the underlying reason for the criticism and the critic is asked to stay away from the issue altogether. Easily confused with the [[association fallacy]] (guilt by association) below.
** [[Bulverism]] (psychogenetic fallacy) – inferring why an argument is being used, associating it to some psychological reason, then assuming it is invalid as a result. The assumption that if the origin of an idea comes from a biased mind, then the idea itself must also be a falsehood.<ref name="Fallacious Arguments" />
* [[Appeal to authority]] (argument from authority, {{lang|la|argumentum ad verecundiam}}) – an assertion is deemed true because of the position or authority of the person asserting it.{{sfn|Clark|Clark|2005|pp=13–16}}{{sfn|Walton|1997|p=28}}
** [[Appeal to accomplishment]] – an assertion is deemed true or false based on the accomplishments of the proposer. This may often also have elements of appeal to emotion {{crossreference|printworthy=y|see below}}.
** [[Courtier's reply]] – a criticism is dismissed by claiming that the critic lacks sufficient knowledge, credentials, or training to credibly comment on the subject matter.
* [[Appeal to consequences]] ({{lang|la|argumentum ad consequentiam}}) – the conclusion is supported by a premise that asserts positive or negative consequences from some course of action in an attempt to distract from the initial discussion.{{sfn|Walton|2008|p=27}}
* [[Appeal to emotion]] – manipulating the emotions of the listener rather than using valid reasoning to obtain common agreement.{{sfn|Damer|2009|p=111}}

** [[Wishful thinking]] – arguing for a course of action by the listener according to what might be pleasing to imagine rather than according to evidence or reason.{{sfn|Damer|2009|p=146}}
* [[Appeal to nature]] – judgment is based solely on whether the subject of judgment is 'natural' or 'unnatural'.{{sfn|Curtis|loc=[http://www.fallacyfiles.org/adnature.html Appeal to Nature]}} (Sometimes also called the "naturalistic fallacy", but is not to be confused with the other fallacies by that name.)
* [[Appeal to novelty]] ({{lang|la|argumentum novitatis}}, {{lang|la|argumentum ad antiquitatis}}) – a proposal is claimed to be superior or better solely because it is new or modern.{{sfn|Pirie|2006|p=116}} (opposite of [[appeal to tradition]])

For instance, ''is'' <math>P \lor \neg P</math> does imply ''ought'' <math>P \lor \neg P</math> for any proposition <math>P</math>, although the ''naturalistic fallacy'' fallacy would falsely declare such an inference invalid. ''Naturalistic fallacy'' fallacy is a type of [[argument from fallacy]].
* [[Straw man]] fallacy – refuting an argument different from the one actually under discussion, while not recognizing or acknowledging the distinction.<ref name="Stephen Downes">{{cite web |url=http://web.uvic.ca/psyc/skelton/Teaching/General%20Readings/Logical%20Falllacies.htm#_Toc495459590 |author=Downes, Stephen |title=The Logical Fallacies |access-date=25 February 2016 |url-status=dead |archive-url=https://web.archive.org/web/20160303181716/http://web.uvic.ca/psyc/skelton/Teaching/General%20Readings/Logical%20Falllacies.htm#_Toc495459590 |archive-date=3 March 2016 }}</ref>

* {{lang|la|[[Tu quoque]]}} ('you too' – appeal to hypocrisy, [[whataboutism]]) – stating that a position is false, wrong, or should be disregarded because its proponent fails to act consistently in accordance with it.{{sfn|Pirie|2006|p=164}}
* [[Two wrongs make a right]] – assuming that, if one wrong is committed, another wrong will rectify it.{{sfn|Johnson|Blair|1994|p=122}}
* [[Vacuous truth]] – a claim that is technically true but meaningless, in the form no ''A'' in ''B'' has ''C'', when there is no ''A'' in ''B''. For example, claiming that no mobile phones in the room are on when there are no mobile phones in the room.
