Truthiness

From Wikipedia, the free encyclopedia

Stephen Colbert uses "truthiness" on the debut episode of The Colbert Report

Truthiness is the belief or assertion that a particular statement is true based on the intuition or perceptions of some individual or individuals, without regard to evidence, logic, intellectual examination, or facts. Truthiness can range from ignorant assertions of falsehoods to deliberate duplicity or propaganda intended to sway opinions.

The concept of truthiness has emerged as a major subject of discussion surrounding U.S. politics during the 1990s and 2000s because of the perception among some observers of a rise in propaganda and a growing hostility toward factual reporting and fact-based discussion.

American television comedian Stephen Colbert coined the term truthiness in this meaning as the subject of a segment called "The Wørd" during the pilot episode of his political satire program The Colbert Report on October 17, 2005. By using this as part of his routine, Colbert satirized the misuse of appeal to emotion and "gut feeling" as a rhetorical device in contemporaneous socio-political discourse. He particularly applied it to U.S. President George W. Bush's nomination of Harriet Miers to the Supreme Court and the decision to invade Iraq in 2003. Colbert later ascribed truthiness to other institutions and organizations, including Wikipedia. Colbert has sometimes used a Dog Latin version of the term, "Veritasiness". For example, in Colbert's "Operation Iraqi Stephen: Going Commando" the word "Veritasiness" can be seen on the banner above the eagle on the operation's seal. 

Truthiness was named Word of the Year for 2005 by the American Dialect Society and for 2006 by Merriam-Webster. Linguist and OED consultant Benjamin Zimmer pointed out that the word truthiness already had a history in literature and appears in the Oxford English Dictionary (OED), as a derivation of truthy, and The Century Dictionary, both of which indicate it as rare or dialectal, and to be defined more straightforwardly as "truthfulness, faithfulness". Responding to claims by Michael Adams that the word already existed with a different meaning, Colbert said, "Truthiness is a word I pulled right out of my keister".

Use by Stephen Colbert

Stephen Colbert, portraying his character Dr. Stephen T. Colbert, chose the word truthiness just moments before taping the premiere episode of The Colbert Report on October 17, 2005, after deciding that the originally scripted word – "truth" – was not absolutely ridiculous enough: "We're not talking about truth, we're talking about something that seems like truth – the truth we want to exist", he explained. He introduced his definition in the first segment of the episode, saying: "Now I'm sure some of the 'word police', the 'wordinistas' over at Webster's are gonna say, 'Hey, that's not a word'. Well, anybody who knows me knows I'm no fan of dictionaries or reference books. They're elitist. Constantly telling us what is or isn't true. Or what did or didn't happen."

When asked in an out-of-character interview with The Onion's A.V. Club for his views on "the 'truthiness' imbroglio that's tearing our country apart", Colbert elaborated on the critique he intended to convey with the word:
Truthiness is tearing apart our country, and I don't mean the argument over who came up with the word ...

It used to be, everyone was entitled to their own opinion, but not their own facts. But that's not the case anymore. Facts matter not at all. Perception is everything. It's certainty. People love the President [George W. Bush] because he's certain of his choices as a leader, even if the facts that back him up don't seem to exist. It's the fact that he's certain that is very appealing to a certain section of the country. I really feel a dichotomy in the American populace. What is important? What you want to be true, or what is true?...

Truthiness is 'What I say is right, and [nothing] anyone else says could possibly be true.' It's not only that I feel it to be true, but that I feel it to be true. There's not only an emotional quality, but there's a selfish quality.
During an interview on December 8, 2006, with Charlie Rose, Colbert stated:
I was thinking of the idea of passion and emotion and certainty over information. And what you feel in your gut, as I said in the first Wørd we did, which was sort of a thesis statement of the whole show – however long it lasts – is that sentence, that one word, that's more important to, I think, the public at large, and not just the people who provide it in prime-time cable, than information.
On his April 2, 2009 episode of The Colbert Report, Colbert added an addendum to the definition: a word so straight that it drives men wild.

Coverage by news media

After Colbert's introduction of truthiness, it quickly became widely used and recognized. Six days after, CNN's Reliable Sources featured a discussion of The Colbert Report by host Howard Kurtz, who played a clip of Colbert's definition. On the same day, ABC's Nightline also reported on truthiness, prompting Colbert to respond by saying: "You know what was missing from that piece? Me. Stephen Colbert. But I'm not surprised. Nightline's on opposite me..."


The February 13, 2006 issue of Newsweek featured an article on The Colbert Report titled "The Truthiness Teller", recounting the career of the word truthiness since its popularization by Colbert.

The New York Times coverage and usage

In its issue of October 25, 2005, eight days after the premiere episode of the Report, The New York Times ran its third article on The Colbert Report, "Bringing Out the Absurdity of the News". The article specifically discussed the segment on "truthiness", although the Times misreported the word as "trustiness". In its November 1, 2005 issue, the Times ran a correction. On the next episode of the Report, Colbert took the Times to task for the error, pointing out, ironically, that "trustiness" is "not even a word".

The New York Times again discussed "truthiness" in its issue of December 25, 2005, this time as one of nine words that had captured the year's zeitgeist, in an article titled "2005: In a Word; Truthiness" by Jacques Steinberg. In crediting truthiness, Steinberg said, "the pundit who probably drew the most attention in 2005 was only playing one on TV: Stephen Colbert".

In the January 22, 2006 issue, columnist Frank Rich used the term seven times, with credit to Colbert, in a column titled "Truthiness 101: From Frey to Alito", to discuss Republican portrayals of several issues (including the Samuel Alito nomination, the Bush administration's response to Hurricane Katrina, and Jack Murtha's Vietnam War record). Rich emphasized the extent to which the word had quickly become a cultural fixture, writing, "The mock Comedy Central pundit Stephen Colbert's slinging of the word 'truthiness' caught on instantaneously last year precisely because we live in the age of truthiness." Editor & Publisher reported on Rich's use of "truthiness" in his column, saying he "tackled the growing trend to 'truthiness,' as opposed to truth, in the U.S."

The New York Times published two letters on the 2006 White House Correspondents' Dinner, where Stephen Colbert was the featured guest, in its May 3, 2006 edition, under the headline "Truthiness and Power".

Frank Rich referenced truthiness again in The New York Times in 2008, describing the strategy of John McCain's presidential campaign as being "to envelop the entire presidential race in a thick fog of truthiness", Rich explained that the campaign was based on truthiness because "McCain, Sarah Palin and their surrogates keep repeating the same lies over and over not just to smear their opponents and not just to mask their own record. Their larger aim is to construct a bogus alternative reality so relentless it can overwhelm any haphazard journalistic stabs at puncturing it." Rich also noted, "You know the press is impotent at unmasking this truthiness when the hardest-hitting interrogation McCain has yet faced on television came on 'The View'. Barbara Walters and Joy Behar called him on several falsehoods, including his endlessly repeated fantasy that Palin opposed earmarks for Alaska. Behar used the word 'lies' to his face."

Widespread recognition

Usage of "truthiness" continued to proliferate in media, politics, and public consciousness. On January 5, 2006, etymology professor Anatoly Liberman began an hour-long program on public radio by discussing truthiness and predicting that it would be included in dictionaries in the next year or two. His prediction seemed to be on track when, the next day, the American Dialect Society announced that "truthiness" was its 2005 Word of the Year, and the website of the Macmillan English Dictionary featured truthiness as its Word of the Week a few weeks later. Truthiness was also selected by The New York Times as one of nine words that captured the spirit of 2005. Global Language Monitor, which tracks trends in languages, named truthiness the top television buzzword of 2006, and another term Colbert coined with reference to truthiness, wikiality, as another of the top ten television buzzwords of 2006, the first time two words from the same show have made the list.

The word was listed in the annual "Banished Word List" released by a committee at Lake Superior State University in Sault Ste. Marie, Michigan in 2007. The list included "truthiness" among other overused terms, such as "awesome" celebrity couple portmanteaus such as "Brangelina", and "pwn". In response, on January 8, 2007 Colbert stated that Lake Superior State University was an "attention-seeking second-tier state university". The 2008 List of Banished Words restored "truthiness" to formal usage, in response to the 2007–2008 Writers Guild of America strike.

American Dialect Society's Word of the Year

On January 6, 2006, the American Dialect Society announced that "truthiness" was selected as its 2005 Word of the Year. The Society described its rationale as follows:
In its 16th annual words of the year vote, the American Dialect Society voted truthiness as the word of the year. First heard on The Colbert Report, a satirical mock news show on the Comedy Central television channel, truthiness refers to the quality of preferring concepts or facts one wishes or believes to be true, rather than concepts or facts known to be true. As Stephen Colbert put it, "I don't trust books. They're all fact, no heart."

Merriam-Webster's Word of the Year

On December 10, 2006 the Merriam-Webster Dictionary announced that "truthiness" was selected as its 2006 Word of the Year on Merriam-Webster's Words of the Year, based on a reader poll, by a 5–1 margin over the second-place word google. "We're at a point where what constitutes truth is a question on a lot of people's minds, and truth has become up for grabs", said Merriam-Webster president John Morse. "'Truthiness' is a playful way for us to think about a very important issue." However, despite winning Word of the Year, the word does not appear in the 2006 edition of the Merriam-Webster English Dictionary. In response to this omission, during "The Wørd" segment on December 12, 2006 Colbert issued a new page 1344 for the tenth edition of the Merriam Webster dictionary that featured "truthiness". To make room for the definition of "truthiness", including a portrait of Colbert, the definition for the word "try" was removed with Colbert stating "Sorry, try. Maybe you should have tried harder." He also sarcastically told viewers to "not" download the new page and "not" glue it in the new dictionary in libraries and schools.

The New York Times crossword puzzle

In the June 14, 2008 edition of The New York Times, the word was featured as 1-across in the crossword puzzle. Colbert mentioned this during the last segment on the June 18 episode of The Daily Show with Jon Stewart, and declared himself the "King of the Crossword".

BBC "portrait of the decade"

In December 2009, the BBC online magazine asked its readers to nominate suggestions of things to be included on a poster which would represent important events in the 2000s (decade), divided into five different categories: "People", "Words", "News", "Objects" and "Culture". Suggestions were sent in and a panel of five independent experts shortened each category to what they saw as the 20 most important. Among the nominations selected in the "Words" category was "Truthiness". As a result, the word "Truthiness" appeared in the poster.

Research

In 2012, a study examining truthiness was carried out by PhD student Eryn Newman of Victoria University of Wellington. The experiments showed that people are more likely to believe that a claim is true regardless of evidence when a decorative photograph appears alongside it.

What Happened

Hillary Clinton mentions the word in her 2017 book What Happened regarding the national dissolution of objective facts.

Use in political and social commentary

Kitty Genovese case retrospective

As noted by Jesse Singal in an April 5, 2016 piece "How the False Story of Kitty Genovese’s Murder Went Viral" in New York magazine upon the death of Kitty Genovese's murderer, the entire escalation of a myth surrounding the murder, alleging that 38 people had been silent witnesses allowing a vicious death to proceed in front of them, was attributable to the myth's appeal to "truthiness" (grounded in fear – of insecurity and lack of community spirit) over full investigation into actual truth:
Today, of course, there is exponentially more news coverage than there was in 1964 — not to mention exponentially more attempts to slot attention-getting events into simple, truthy stories about human nature. The gap between the famous version of the Genovese story and the true one, then, is worth remembering, if only as a check on our natural tendency to hear a story and then nod along and say, 'Of course that’s what happened!'

James Frey controversy

The Chicago Tribune published an editorial in its January 16, 2006 issue titled "The Truthiness Hurts", crediting the rise of truthiness as serendipitously providing an apt description of the Oprah Book Club controversy over James Frey's fictionalized "memoir", A Million Little Pieces. Truthiness was also used to describe the controversy over the factual accuracy of Frey's book by USA Today in its January 15, 2006 issue, by several other publications including The New York Times, and by the television news program Nightline on its October 23 and January 26 editions.

Oprah Winfrey also discussed truthiness with Frank Rich on her show, in reference to the Frey controversy and the column "Truthiness 101" Rich had recently published in The New York Times. They also mentioned Colbert's role in making the word "truthiness".

On January 27, MSNBC ran a commentary titled "Oprah strikes a blow for truthiness: Do facts really matter? Ask Winfrey, James Frey or Stephen Colbert", making the case that Winfrey's about-face on Frey's book was a "small (and belated) but bold nudge back out of the proud halls of truthiness", but also opportunistic and too little too late.

In the Canadian Parliament

In 2006, Liberal Party of Canada leadership contender Ken Dryden used truthiness as an extensive theme in a speech in the House of Commons. The speech dealt critically with the Harper government's Universal Child Care Plan. Dryden defined truthiness as "something that is spoken as if true that one wants others to believe is true, that said often enough with enough voices orchestrated in behind it, might even sound true, but is not true."

The transcript of all debates in the House (Hansard) is made available in both official languages; the translators into French chose to render "truthiness" as fausse vérité ("false truth").

Alleged snubbing by the Associated Press, and Colbert's response

The Associated Press reported on the American Dialect Society's selection of truthiness as the Word of the Year, including the following comments by one of the voting linguists:
Michael Adams, a professor at North Carolina State University who specializes in lexicology, said "truthiness" means "truthy, not facty". "The national argument right now is, one, 'Who's got the truth?' and, two, 'Who's got the facts?'" he said. "Until we can manage to get the two of them back together again, we're not going to make much progress."
On each of the first four episodes of the Report after the selection of truthiness as Word of the Year, Colbert lamented that news reports neglected to acknowledge him as the source of the word. On the first of these episodes, he added Michael Adams to his "On Notice" board, and Associated Press reporter Heather Clark, the author of the article, to his "Dead to Me" board:
"You see, the Associated Press article announcing this prestigious award, written by one Heather Clark, had a glaring omission: me," Colbert said during his show Monday. "I'm not mentioned, despite the fact that truthiness is a word I pulled right out of my keister."
Later Adams admitted the "absolutely hilarious" nature of the show and said he couldn't "think of any greater honor than to be placed on Colbert's 'On Notice' board," and that he "owes Colbert thanks."

On the third of these episodes, he ranked the AP at the top of the "Threat-Down", one of few entries ever to gain the number one spot in place of bears. On the following episode he called Adams and asked for an apology. Though Adams never apologized, Colbert "accepted" his "apology", but failed to take him "off notice".

Associated Press response to Colbert

On January 13, the first day after the four-day run of criticism of the AP on the Report, the AP ran a story about The Colbert Report being upset about being snubbed by the AP, in an article titled "Colbert: AP the biggest threat to America". As he has in the past, Colbert remained in character in an interview for the story, and used it to further the political satire of truthiness; excerpts of the story are:
"When an AP story about the designation sent coast to coast failed to mention Colbert, he began a tongue-in-cheek crusade, not unlike the kind his muse Bill O'Reilly might lead in all seriousness."
"'It's a sin of omission...' Stephen Colbert told the AP on Thursday...'It's like Shakespeare still being alive and not asking him what Hamlet is about,' he said."
"The Oxford English Dictionary has a definition for 'truthy' dating back to the 1800s....'The fact that they looked it up in a book just shows that they don't get the idea of truthiness at all,' Stephen Colbert said Thursday. 'You don't look up truthiness in a book, you look it up in your gut.'"

"Though slight, the difference of Colbert's definition and the OED's is essential. It's not your typical truth, but, as The New York Times wrote, 'a summation of what [Colbert] sees as the guiding ethos of the loudest commentators on Fox News, MSNBC and CNN.'"

"Colbert, who referred on his program to the AP omission as a 'journalistic travesty,' said Thursday that it was similar to the much-criticized weapons of mass destruction reporting leading up to the Iraq War. 'Except,' he said, 'people got hurt this time.'"
On January 14, Clark herself responded in an article titled "Exclusive 'News' – I'm dead to Stephen Colbert". She furthered the rise of "truthiness" in published English in conceding, "Truthiness be told, I never had seen The Colbert Report until my name graced its 'Dead to Me' board this week... But I will say that I watched Colbert's show for the first time...It was funny. And that's not just truthy. That's a fact."

Arianna Huffington

On January 31, 2006, Arianna Huffington used truthiness in The Huffington Post. Huffington later appeared as a guest on the March 1, 2006, episode of The Colbert Report. She challenged Colbert on his claim that he had invented the word truthiness. During the interview, Colbert declared, "I'm not a truthiness fanatic; I'm truthiness' father." Huffington corrected him, citing Wikipedia, that he had merely "popularized" the term. Regarding her source, Colbert responded: "Fuck them!"

President George W. Bush

At the 2006 White House Correspondents' Association Dinner, Colbert, the featured guest, described President Bush's thought processes using the definition of truthiness. Editor and Publisher used "truthiness" to describe Colbert's criticism of Bush, in an article published the same day titled "Colbert Lampoons Bush at White House Correspondents Dinner—President Not Amused?" E&P reported that the "blistering comedy 'tribute' to President Bush ... left George and Laura Bush unsmiling at its close" and that many people at the dinner "looked a little uncomfortable at times, perhaps feeling the material was a little too biting—or too much speaking 'truthiness' to power". E&P reported a few days later that its coverage of Colbert at the dinner drew "possibly its highest one-day traffic total ever", and published a letter to the editor asserting that "Colbert brought truth wrapped in truthiness". On the same weekend, The Washington Post and others also reported on the event. Six months later, in a column titled "Throw The Truthiness Bums Out", The New York Times columnist Frank Rich called Colbert's after-dinner speech a "cultural primary" and christened it the "defining moment" of the United States' 2006 midterm elections.

Charles Krauthammer

Conservative commentator Charles Krauthammer brought the term up in a discussion about President Obama on the show Fox News All-Stars in June 2010, saying:
What we see here is conditional truthiness. When the administration needs to say, oh, we knew how bad it was, it says it, and when it needs to say we had no idea how bad it was, it says it. It depends when it needs it; it'll invent a new truth.

Cato Institute amicus brief

In 2014, the Cato Institute filed an amicus brief to the United States Supreme Court co-authored by humorist P. J. O'Rourke in the Susan B. Anthony List v. Driehaus free speech case. The brief included an extended discussion of the role of truthiness in American political discourse:
In modern times, "truthiness"—a "truth" asserted "from the gut" or because it "feels right," without regard to evidence or logic—is also a key part of political discourse. It is difficult to imagine life without it, and our political discourse is weakened by Orwellian laws that try to prohibit it.


After all, where would we be without the knowledge that Democrats are pinko-communist flag-burners who want to tax churches and use the money to fund abortions so they can use the fetal stem cells to create pot-smoking lesbian ATF agents who will steal all the guns and invite the UN to take over America? Voters have to decide whether we'd be better off electing Republicans, those hateful, assault-weapon-wielding maniacs who believe that George Washington and Jesus Christ incorporated the nation after a Gettysburg reenactment and that the only thing wrong with the death penalty is that it isn't administered quickly enough to secular-humanist professors of Chicano studies.

The Late Show with Stephen Colbert

Colbert refreshed "truthiness" in an episode of The Late Show with Stephen Colbert on July 18, 2016, using the neologism "Trumpiness" regarding statements made by Donald Trump during his presidential campaign. According to Colbert, while truthiness refers to statements that feel true but are actually false, "Trumpiness" does not even have to feel true, much less be true. As evidence that Trump's remarks exhibit this quality, he cited a Washington Post column stating that many Trump supporters did not believe his "wildest promises" but supported him anyway.

List of fallacies

From Wikipedia, the free encyclopedia

In reasoning to argue a claim, a fallacy is reasoning that is evaluated as logically incorrect and that undermines the logical validity of the argument and permits its recognition as unsound. Regardless of their soundness, all registers and manners of speech can demonstrate fallacies.
 
Because of their variety of structure and application, fallacies are challenging to classify so as to satisfy all practitioners. Fallacies can be classified strictly by either their structure or content, such as classifying them as formal fallacies or informal fallacies, respectively. The classification of informal fallacies may be subdivided into categories such as linguistic, relevance through omission, relevance through intrusion, and relevance through presumption. On the other hand, fallacies may be classified by the process by which they occur, such as material fallacies (content), verbal fallacies (linguistic), and again formal fallacies (error in inference). In turn, material fallacies may be placed into the more general category of informal fallacies, while formal fallacies may be clearly placed into the more precise category of logical (deductive) fallacies. Yet, verbal fallacies may be placed into either informal or deductive classifications; compare equivocation which is a word or phrase based ambiguity, e. g. "he is mad", which may refer to either him being angry or clinically insane, to the fallacy of composition which is premise and inference based ambiguity, e. g. "this must be a good basketball team because each of its members is an outstanding player".

Faulty inferences in deductive reasoning are common formal or logical fallacies. As the nature of inductive reasoning is based on probability, a fallacious inductive argument or one that is potentially misleading, is often classified as "weak".

The conscious or habitual use of fallacies as rhetorical devices are prevalent in the desire to persuade when the focus is more on communication and eliciting common agreement rather than the correctness of the reasoning. The effective use of a fallacy by an orator may be considered clever, but by the same token, the reasoning of that orator should be recognized as unsound, and thus the orator's claim, supported by an unsound argument, will be regarded as unfounded and dismissed.

Formal fallacies

A formal fallacy is an error in logic that can be seen in the argument's form. All formal fallacies are specific types of non sequiturs.
  • Appeal to probability – a statement that takes something for granted because it would probably be the case (or might be the case).
  • Argument from fallacy (also known as the fallacy fallacy) – assumption that if an argument for some conclusion is fallacious, then the conclusion is false.
  • Base rate fallacy – making a probability judgment based on conditional probabilities, without taking into account the effect of prior probabilities.
  • Conjunction fallacy – assumption that an outcome simultaneously satisfying multiple conditions is more probable than an outcome satisfying a single one of them.
  • Masked-man fallacy (illicit substitution of identicals) – the substitution of identical designators in a true statement can lead to a false one.

Propositional fallacies

A propositional fallacy is an error in logic 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: , , , , ). The following fallacies involve inferences whose correctness is not guaranteed by the behavior of those logical connectives, and hence, which are not logically guaranteed to yield true conclusions.

Types of propositional fallacies:

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. 

Types of quantification fallacies:
  • Existential fallacy – an argument that has a universal premise and a particular conclusion.

Formal syllogistic fallacies

Syllogistic fallacies – logical fallacies that occur in syllogisms.

Informal fallacies

Informal fallacies – arguments that are fallacious for reasons other than structural (formal) flaws and usually require examination of the argument's content.
  • Argument to moderation (false compromise, middle ground, fallacy of the mean, argumentum ad temperantiam) – assuming that the compromise between two positions is always correct.
  • Continuum fallacy (fallacy of the beard, line-drawing fallacy, sorites fallacy, fallacy of the heap, bald man fallacy) – improperly rejecting a claim for being imprecise.
  • Correlative-based fallacies
  • Divine fallacy (argument from incredulity) – arguing that, because something is so incredible or amazing, it must be the result of superior, divine, alien or paranormal agency.
  • 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.
  • Equivocation – the misleading use of a term with more than one meaning (by glossing over which meaning is intended at a particular time).
    • Ambiguous middle term – a common ambiguity in syllogisms in which the middle term is equivocated.
    • Definitional retreat – changing the meaning of a word to deal with an objection raised against the original wording.
    • Motte-and-bailey fallacy – The arguer conflates two similar positions, one modest and easy to defend (the "motte") and one much more controversial (the "bailey"). The arguer advances the controversial position, but when challenged, they insist that they are only advancing the more modest position.
    • Fallacy of accent – a specific type of ambiguity that arises when the meaning of a sentence is changed by placing an unusual prosodic stress, or when, in a written passage, it's left unclear which word the emphasis was supposed to fall on.
    • (See also the if-by-whiskey fallacy, below.)
  • Ecological fallacy – inferences about the nature of specific individuals are based solely upon aggregate statistics collected for the group to which those individuals belong.
  • Etymological fallacy – reasoning that the original or historical meaning of a word or phrase is necessarily similar to its actual present-day usage.
  • Fallacy of composition – assuming that something true of part of a whole must also be true of the whole.
  • Fallacy of division – assuming that something true of a thing must also be true of all or some of its parts.
  • False attribution – an advocate appeals to an irrelevant, unqualified, unidentified, biased or fabricated source in support of an argument.
    • Fallacy of quoting out of context (contextotomy, contextomy; quotation mining) – refers to the selective excerpting of words from their original context in a way that distorts the source's intended meaning.
  • False authority (single authority) – using an expert of dubious credentials or using only one opinion to sell a product or idea. Related to the appeal to authority (not always fallacious).
  • False dilemma (false dichotomy, fallacy of bifurcation, black-or-white fallacy) – two alternative statements are held to be the only possible options when in reality there are more.
  • False equivalence – describing a situation of logical and apparent equivalence, when in fact there is none.
  • Historian's fallacy – the assumption that decision makers of the past viewed events from the same perspective and had the same information as those subsequently analyzing the decision. (Not to be confused with presentism, which is a mode of historical analysis in which present-day ideas, such as moral standards, are projected into the past.)
  • Historical fallacy – a set of considerations is thought to hold good only because a completed process is read into the content of the process which conditions this completed result.
  • Homunculus fallacy – a "middle-man" is used for explanation; this sometimes leads to regressive middle-men. Explains without actually explaining the real nature of a function or a process. Instead, it explains the concept in terms of the concept itself, without first defining or explaining the original concept. Explaining thought as something produced by a little thinker, a sort of homunculus inside the head, merely explains it as another kind of thinking (as different but the same).
  • Inflation of conflict – arguing that if experts of a field of knowledge disagree on a certain point, the experts must know nothing, and therefore no conclusion can be reached, or that the legitimacy of their entire field is put to question.
  • If-by-whiskey – an argument that supports both sides of an issue by using terms that are selectively emotionally sensitive.
  • Incomplete comparison – insufficient information is provided to make a complete comparison.
  • Inconsistent comparison – different methods of comparison are used, leaving a false impression of the whole comparison.
  • 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.)
  • Kettle logic – using multiple, jointly inconsistent arguments to defend a position.
  • Ludic fallacy – the belief that the outcomes of non-regulated random occurrences can be encapsulated by a statistic; a failure to take into account unknown unknowns in determining the probability of events taking place.
  • McNamara fallacy (quantitative fallacy) – making a decision based only on quantitative observations, discounting all other considerations.
  • Mind projection fallacy – subjective judgments are "projected" to be inherent properties of an object, rather than being related to personal perceptions of that object.
  • Moralistic fallacy – inferring factual conclusions from purely evaluative premises in violation of fact–value distinction. For instance, inferring is from ought is an instance of moralistic fallacy. Moralistic fallacy is the inverse of naturalistic fallacy defined below.
  • 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.
  • Onus probandi – from the Latin onus probandi incumbit ei qui dicit, non ei qui negat the burden of proof is on the person who makes the claim, not on the person who denies (or questions the claim). It is a particular case of the argumentum ad ignorantiam fallacy, here the burden is shifted on the person defending against the assertion. Also known as "shifting the burden of proof".
  • Proof by assertion – a proposition is repeatedly restated regardless of contradiction; sometimes confused with argument from repetition (argumentum ad infinitum, argumentum ad nauseam)
  • Prosecutor's fallacy – a low probability of false matches does not mean a low probability of some false match being found.
  • Proving too much – using a form of argument that, if it were valid, could be used to reach an additional, invalid conclusion.
  • Psychologist's fallacy – an observer presupposes the objectivity of their own perspective when analyzing a behavioral event.
  • Referential fallacy – assuming 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 or that the meaning of words often comes from how they are used.
  • Reification (concretism, hypostatization, or the fallacy of misplaced concreteness) – a fallacy of ambiguity, when an abstraction (abstract belief or hypothetical construct) is treated as if it were a concrete, real event or physical entity. In other words, it is the error of treating as a "real thing" something that is not a real thing, but merely an idea.
  • Retrospective determinism – the argument that because an event has occurred under some circumstance, the circumstance must have made its occurrence inevitable.
  • Special pleading – a proponent of a position attempts to cite something as an exemption to a generally accepted rule or principle without justifying the exemption.

Improper premise

  • Begging the question (petitio principii) – providing what is essentially the conclusion of the argument as a premise.
    • Loaded label – while not inherently fallacious, 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, an organic foods advertisement that says "Organic foods are safe and healthy foods grown without any pesticides, herbicides, or other unhealthy additives." Use of the term "unhealthy additives" is used as support for the idea that the product is safe.
  • Circular reasoning (circulus in demonstrando) – the reasoner begins with what he or she is trying to end up with; sometimes called assuming the conclusion.
  • Fallacy of many questions (complex question, fallacy of presuppositions, loaded question, 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.

Faulty generalizations

Faulty generalization – reach a conclusion from weak premises. Unlike fallacies of relevance, in fallacies of defective induction, the premises are related to the conclusions yet only weakly buttress the conclusions. A faulty generalization is thus produced.
  • Accident – an exception to a generalization is ignored.
    • No true Scotsman – makes a generalization true by changing the generalization to exclude a counterexample.
  • Cherry picking (suppressed evidence, incomplete evidence) – act of pointing at individual cases or data that seem to confirm a particular position, while ignoring a significant portion of related cases or data that may contradict 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.
  • 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 sample or the making of a determination without all of the information required to do so.
  • Inductive fallacy – A more general name to some fallacies, such as hasty generalization. It happens when a conclusion is made of premises that 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 a problem; 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.
  • 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 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.
  • 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.
    • 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.
    • Wrong direction (reverse causation) – cause and effect are reversed. The cause is said to be the effect and vice versa. The consequence of the phenomenon is claimed to be its root cause.
    • Ignoring a common cause
  • Fallacy of the single cause (causal oversimplification) – 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.
  • Furtive fallacy – outcomes are asserted to have been caused by the malfeasance of decision makers.
  • 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.
  • 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.
  • 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.

Relevance fallacies

  • Appeal to the stone (argumentum ad lapidem) – dismissing a claim as absurd without demonstrating proof for its absurdity.
  • Argument from ignorance (appeal to ignorance, argumentum ad ignorantiam) – assuming that a claim is true because it has not been or cannot be proven false, or vice versa.
  • Argument from incredulity (appeal to common sense) – "I cannot imagine how this could be true; therefore, it must be false."
  • Argument from repetition (argumentum ad nauseam, argumentum ad infinitum) – repeating an argument until nobody cares to discuss it any more; sometimes confused with proof by assertion
  • Argument from silence (argumentum ex silentio) – assuming that a claim is true based on the absence of textual or spoken evidence from an authoritative source, or vice versa.
  • Ignoratio elenchi (irrelevant conclusion, missing the point) – an argument that may in itself be valid, but does not address the issue in question.

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. In the general case any logical inference based on fake arguments, intended to replace the lack of real arguments or to replace implicitly the subject of the discussion.

Red herring – a speaker attempts to distract an audience by deviating from the topic at hand by introducing a separate argument the speaker believes is easier to speak to. Argument given in response to another argument, which is irrelevant and draws attention away from the subject of argument.
  • Ad hominem – attacking the arguer instead of the argument.
    • Circumstantial ad hominem - stating that the arguers personal situation or perceived benefit from advancing a conclusion means that their conclusion is wrong.
    • Poisoning the well – a subtype of ad hominem presenting adverse information about a target person with the intention of discrediting everything that the target person says.
    • Abusive fallacy – verbally abusing the opponent rather than arguing about the originally proposed argument.
    • Appeal to motive – dismissing an idea by questioning the motives of its proposer.
    • Kafka-trapping – a sophistical and unfalsifiable form of argument that attempts to overcome an opponent by inducing a sense of guilt and using the opponent's denial of guilt as further evidence of guilt.
    • Tone policing – focusing on emotion behind (or resulting from) a message rather than the message itself as a discrediting tactic.
    • Traitorous critic fallacy (ergo decedo, 'thus 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.
  • Appeal to authority (argument from authority, argumentum ad verecundiam) – an assertion is deemed true because of the position or authority of the person asserting it. The term is also used more broadly to describe arguments that are not always fallacious; see entry in the Conditional or questionable fallacies section.
    • 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 (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 (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.
  • Appeal to emotion – an argument is made due to the manipulation of emotions, rather than the use of valid reasoning.
    • Appeal to fear – an argument is made by increasing fear and prejudice towards the opposing side
    • Appeal to flattery – an argument is made due to the use of flattery to gather support.
    • Appeal to pity (argumentum ad misericordiam) – an argument attempts to induce pity to sway opponents.
    • Appeal to ridicule – an argument is made by incorrectly presenting the opponent's argument in a way that makes it appear ridiculous.
    • Appeal to spite – an argument is made through exploiting people's bitterness or spite towards an opposing party.
    • Judgmental language – insulting or pejorative language to influence the audience's judgment.
    • Pooh-pooh – dismissing an argument perceived unworthy of serious consideration.
    • Wishful thinking – a decision is made according to what might be pleasing to imagine, rather than according to evidence or reason.
  • Appeal to nature – judgment is based solely on whether the subject of judgment is 'natural' or 'unnatural'. (Sometimes also called the "naturalistic fallacy", but is not to be confused with the other fallacies by that name.)
  • Appeal to novelty (argumentum novitatis, argumentum ad antiquitatis) – a proposal is claimed to be superior or better solely because it is new or modern.
  • Appeal to poverty (argumentum ad Lazarum) – supporting a conclusion because the arguer is poor (or refuting because the arguer is wealthy). (Opposite of appeal to wealth.)
  • Appeal to tradition (argumentum ad antiquitatem) – a conclusion supported solely because it has long been held to be true.
  • Appeal to wealth (argumentum ad crumenam) – supporting a conclusion because the arguer is wealthy (or refuting because the arguer is poor). (Sometimes taken together with the appeal to poverty as a general appeal to the arguer's financial situation.)
  • Argumentum ad baculum (appeal to the stick, appeal to force, appeal to threat) – an argument made through coercion or threats of force to support position.
  • Argumentum ad populum (appeal to widespread belief, bandwagon argument, appeal to the majority, appeal to the people) – a proposition is claimed to be true or good solely because a majority or many people believe it to be so.
  • Association fallacy (guilt by association and honor by association) – arguing that because two things share (or are implied to share) some property, they are the same.
  • Ipse dixit (bare assertion fallacy) – a claim that is presented as true without support, as self-evidently true, or as dogmatically true. This fallacy relies on the implied expertise of the speaker or on an unstated truism.
  • 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.
  • Chronological snobbery – a thesis is deemed incorrect because it was commonly held when something else, known to be false, was also commonly held.
  • Fallacy of relative privation (also known as "appeal to worse problems" or "not as bad as") – dismissing an argument or complaint due to the existence of more important problems in the world, regardless of whether those problems bear relevance to the initial argument. First World problems are a subset of this fallacy.
  • Genetic fallacy – a conclusion is suggested based solely on something or someone's origin rather than its current meaning or context.
  • Moralistic fallacy – inferring factual conclusions from evaluative premises, in violation of fact–value distinction; e.g. making statements about what is, on the basis of claims about what ought to be. This is the inverse of the naturalistic fallacy.
  • Naturalistic fallacy – inferring evaluative conclusions from purely factual premises in violation of fact–value distinction. Naturalistic fallacy in the stricter sense defined in the section "Conditional or questionable fallacies" (below) is a variety of this broader sense. Naturalistic fallacy (sometimes confused with appeal to nature) is the inverse of moralistic fallacy.
    • Is–ought fallacy – statements about what is, on the basis of claims about what ought to be.
  • Naturalistic fallacy fallacy (anti-naturalistic fallacy) – inferring an impossibility to infer any instance of ought from is from the general invalidity of is-ought fallacy, mentioned above. For instance, is does imply ought for any proposition , 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 – an argument based on misrepresentation of an opponent's position.
  • Texas sharpshooter fallacy – improperly asserting a cause to explain a cluster of data.
  • Tu quoque ('you too' – appeal to hypocrisy, whataboutism) – the argument states that a certain position is false or wrong or should be disregarded because its proponent fails to act consistently in accordance with that position.
  • Two wrongs make a right – occurs when it is assumed that if one wrong is committed, another wrong will rectify it.
  • Vacuous truth – a claim that is technically true but meaningless, in the form of claiming that 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 at all.

Conditional or questionable fallacies

  • Appeal to authority (argument from authority, argumentum ad verecundiam) – a form of defeasible argument in which a claimed authority's support is used as evidence for an argument's conclusion. The argument may actually be cogent when all sides of a discussion agree on the reliability of the authority in the given context. See the Red herring fallacies section, above, for the fallacious variant.
  • Broken window fallacy – an argument that disregards lost opportunity costs (typically non-obvious, difficult to determine or otherwise hidden) associated with destroying property of others, or other ways of externalizing costs onto others. For example, an argument that states breaking a window generates income for a window fitter, but disregards the fact that the money spent on the new window cannot now be spent on new shoes.
  • Definist fallacy – involves the confusion between two notions by defining one in terms of the other.
  • The ends justify the means – an assertion that may or may not be defensible depending on the ends and means in question. The various approaches to this sort of question are the subject of the normative ethical theories of consequentialism.
  • Naturalistic fallacy – attempts to prove a claim about ethics by appealing to a definition of the term "good" in terms of either one or more claims about natural properties. The naturalistic fallacy also has a more general version, covered in the "Red herring fallacies" section, above.
  • Slippery slope (thin edge of the wedge, camel's nose) – asserting that a relatively small first step inevitably leads to a chain of related events culminating in some significant impact/event that should not happen, thus the first step should not happen. It is, in its essence, an appeal to probability fallacy.
