Fallacies
statement errors VS logic of rationality

---------------------------------------------------------------------------------

In using reasoning as support for a claim in an argument, a fallacy is reasoning that is evaluated as logically incorrect, which undermines an argument's logical validity and leads to a recognition of an argument being unsound. Regardless of their lack of soundness, all registers and manners of speech can demonstrate the usage of fallacies.

Due to their variety in structure and application, fallacies are a challenge to classify to satisfy all practitioners. Fallacies can be classified strictly by either their structure or their content, such as classifying them as formal fallacies or informal fallacies, respectively. The classification of informal fallacies may be further subdivided into categories such as the following: linguistic, relevance through omission, relevance through intrusion, and relevance through presumption.[1] On the other hand, fallacies may be classified by the process through which the fallacy occurs, 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 generalized category of informal fallacies as formal fallacies may be clearly placed into the more precise category of logical or deductive fallacies. Yet, verbal fallacies may be placed in either informal or deductive classifications—compare equivocation which is word or phrase based ambiguity (Example: '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 (Example: This must be a good basketball team because each of its members is an outstanding player).[2]

Faulty inferences through deductive reasoning are common formal or logical fallacies. As the nature of inductive reasoning is based in probability, a fallacious inductive reason, or one that has the potential to mislead, is often classified as weak.

The conscious or habitual usage of fallacies as rhetorical tools are prevalent in the desire to persuade people, where the focus is more on communication and developing common agreement rather than the correctness of the reasoning. One may consider the effective use of a fallacy by an orator as clever but by the same token the reasoning of that orator should be recognized as unsound, and thus their claim, supported by an unsound argument, will be regarded as unfounded and generally dismissed.[3]

Formal Fallacies	

A formal fallacy is an error in logic that can be seen in the argument's form.[4] All formal fallacies are specific types of non sequiturs.

Name    //////	   Description
Appeal to probability – is 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 fallacy fallacy, assumes that if an argument for some conclusion is fallacious, then the conclusion is false. It is not solely because an argument contains a fallacy that it is to be perceived entirely as false, or as not containing a specific real intent to mean something (supposedly capable of being rectified/refined by perception of the argument regarding the argument's intent and content).
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: <and>, <or>, <not>, <only if>, <if and only if>). 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.

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.
Affirming the consequent – the antecedent in an indicative conditional is claimed to be true because the consequent is true; if A, then B; B, therefore A.
Denying the antecedent – the consequent in an indicative conditional is claimed to be false because the antecedent is false; if A, then B; not A, therefore not B.[11]

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.

Existential fallacy – an argument that has a universal premise and a particular conclusion.

Syllogistic Fallacies	

Syllogistic fallacies – logical fallacies that occur in syllogisms.

Affirmative conclusion from a negative premise (illicit negative) – when a categorical syllogism has a positive conclusion, but at least one negative premise.[12]
Fallacy of exclusive premises – a categorical syllogism that is invalid because both of its premises are negative.[12]
Fallacy of four terms (quaternio terminorum) – a categorical syllogism that has four terms.[13]
Illicit major – a categorical syllogism that is invalid because its major term is not distributed in the major premise but distributed in the conclusion.[12]
Illicit minor – a categorical syllogism that is invalid because its minor term is not distributed in the minor premise but distributed in the conclusion.[12]
Negative conclusion from affirmative premises (illicit affirmative) – when a categorical syllogism has a negative conclusion but affirmative premises.[12]
Fallacy of the undistributed middle – the middle term in a categorical syllogism is not distributed.[14]

Informal Fallacies	

Arguments that are fallacious for reasons other than structural (formal) flaws and usually require examination of the argument's content.[15]

Appeal to the stone (argumentum ad lapidem) – dismissing a claim as absurd/non-sensical without demonstrating proof for its absurdity/non-sense.[16]
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; assuming that a claim is false because it has not been or cannot be proven true.[17] Example: Claiming that God (The Christian God) does not exist, with certainty. Or claiming that God (The Christian God) does exist, with certainty.
Argument from incredulity (appeal to common sense) – "I cannot imagine how this could be true; therefore, it must be false."[18]
Argument from repetition (argumentum ad nauseam, argumentum ad infinitum) – signifies that it has been discussed extensively until nobody concerns discussion anymore;[19][20] sometimes confused with proof by assertion
Argument from silence (argumentum ex silentio) – where the conclusion is based on the absence of evidence, rather than the existence of evidence.[21][22]
Argument to moderation (false compromise, middle ground, fallacy of the mean, argumentum ad temperantiam) – assuming that the compromise between two positions is always correct.[23]
Begging the question (petitio principii) – providing what is essentially the conclusion of the argument as a premise.[24][25][26][27]
Shifting the burden of proof (see – onus probandi) – One needs not to prove a claim, another must prove it is false.
Circular reasoning (circulus in demonstrando) – is a logical fallacy in which the reasoner begins with what is trying to end with.
Circular cause and consequence – where the consequence of the phenomenon is claimed to be its root cause.
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.[28]

Correlative-Based Fallacies

For any two correlated events, A and B, the different possible relationships include[citation needed]:

A causes B (direct causation);
    B causes A (reverse causation);
    In certain cases A and B are consequences of a common cause, but do not cause each other;
    A and B both cause C, which is (explicit or implicit causation) conditioned on;
    A causes B and B causes A (bidirectional or cyclic causation);
    A causes C which causes B (indirect causation);
    In certain cases there is no connection between A and B; the correlation is a coincidence.

Correlation proves causation (post hoc ergo propter hoc) – a faulty assumption that because there is a correlation between two variables that one caused the other.[29]
Suppressed correlative – where a correlative is atrophied by false means so that one alternative is made impossible.[30]
Divine fallacy (argument from incredulity) – arguing that, because something is so incredible/amazing/ununderstandable, it must be the result of superior, divine, alien or paranormal agency.[31]
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). In logic, equivocation ('calling two different things by the same name') is an informal fallacy resulting from the use of a particular word/expression in multiple senses throughout an argument leading to a false conclusion.[1][2] Abbott and Costello's "Who's on first?" routine is a well known example of equivocation.[3][4] It is a type of ambiguity that stems from a phrase having two distinct meanings, not from the grammar or structure of the sentence.[1]  Some examples of equivocation in syllogisms (a logical chain of reasoning) are below:     

Since only man [human] is rational,
and no woman is a man [male],
Therefore, no woman is rational.[1]
A feather is light [not heavy].
What is light [bright] cannot be dark.
Therefore, a feather cannot be dark.

In the above example, distinct meanings of the word "light" are implied in contexts of the first and second statements. 

All jackasses have long ears.
Carl is a jackass.
Therefore, Carl has long ears.

Example 3:
The priest told me I should have faith.
I have faith that my son will do well in school this year.
Therefore, the priest should be happy with me.

Explanation: The term “faith” used by the priest, was in the religious sense of believing in God without sufficient evidence, which is different from having “faith” in your son in which years of good past performance leads to the “faith” you might have in your son.

NOTICE : Equivocation works great when deliberate attempts at humor are being made.

Ambiguous middle term – a common ambiguity in syllogisms in which the middle term is equivocated.[33]
Definitional retreat – changing the meaning of a word to deal with an objection raised against the original wording.[1]
Ecological fallacy – inferences about the nature of specific individuals are based solely upon aggregate statistics collected for the group to which those individuals belong.[34]
Etymological fallacy – which reasons that the original or historical meaning of a word or phrase is necessarily similar to its actual present-day usage.[35]
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.
Fallacy of composition – one infers that something is true of the whole from the fact that it is true of some part. For example: "This tire is made of rubber, therefore the vehicle to which it is a part is also made of rubber." Synecdoche, the figure of speech of two forms: Pars pro toto using the word for a part by way of referring to the whole| Totum pro parte using the word for the whole by way of referring to a part).
Fallacy of division – assuming that something true of a thing must also be true of all or some of its parts.[37]
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 (contextomy) – refers to the selective excerpting of words from their original context in a way that distorts the source's intended meaning.[38]
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 fallacy.
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.[39]
False equivalence – describing a situation of logical and apparent equivalence, when in fact there is none. Two completely opposing arguments appear to be logically equivalent when in fact they are not. A common way for this fallacy to be perpetuated is one shared trait between two subjects is assumed to show equivalence, especially in order of magnitude, when equivalence is not necessarily the logical result. This fallacy is categorized as a fallacy of inconsistency. False equivalence is a common result when an anecdotal similarity is pointed out as equal, but the claim of equivalence doesn't bear because the similarity is based on oversimplification or ignorance of additional factors. Example: "They're both living animals that metabolize chemical energy. There's no difference between a pet cat and a pet snail."
Fallacy of many questions (complex question, fallacy of presupposition, 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. The rhetorical trick of asking a question that cannot be answered without admitting a presupposition that may be false, as "Have you stopped beating your wife?".
Fallacy of the single cause (causal oversimplification[40]) – 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."[41]
Historian's fallacy – occurs when one assumes that decision makers of the past viewed events from the same perspective and having the same information as those subsequently analyzing the decision.[42] (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 – where a set of considerations holds good only because a completed process is read into the content of the process which conditions this completed result.[43] Example: 

Somebody loses the wallet but has an idea of where it might be. 
Looks for the wallet and finds it where thought it may have been. 
Falsely concludes that knew where the wallet was the entire time. 

Homunculus fallacy – where 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, 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).[44] "In terms of (say) chess, the players are given 'rules' (i.e. the rules of chess) to follow. So: who uses these rules? The answer is self-evident: the players of the game (of chess) use the rules: it's not the case (obviously) that the rules themselves play chess."

1: So how do you think life began?
2: Simple. Aliens from another planet seeded this planet with life billions of years ago.
1: OK, but how did that alien life form begin?
2: Simple. Aliens from another planet seeded that planet with life.

Inflation of conflict – The experts of a field of knowledge disagree on a certain point, so the scholars must know nothing, and therefore the legitimacy of their entire field is put to question.[45]
If-by-whiskey – an argument that supports both sides of an issue by using terms that are selectively emotionally sensitive. In political discourse, if-by-whiskey is a relativist fallacy in which the speaker's position is contingent on the listener's opinion. An if-by-whiskey argument implemented through doublespeak appears to affirm both sides of an issue, and agrees with whichever side the listener supports, in effect taking a position without taking a position.[1] The statement typically uses words with strongly positive or negative connotations ("terrorist as negative and freedom fighter as positive").[2]
Incomplete comparison – in which insufficient information is provided to make a complete comparison.
Inconsistent comparison – where different methods of comparison are used, leaving one with 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 (Example: "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.")[46]
Ignoratio elenchi (irrelevant conclusion, missing the point) – an argument that may in itself be valid, but does not address the issue in question.[47] (Example: He's such a nice guy, and he gives a lot of money to all sorts of charities. Clearly, he will end up in the Hall of Fame of Sports.)
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.[48]
Quantitative fallacy – making a decision based only on quantitative observations, discounting all other considerations.
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.

Eating meat harms animals and the environment, and so no one has physiological use for it.

Men and women ought to be given equal opportunities, and so women and men can do everything equally well.

Warfare is destructive and tragic, and so it is not of human nature.

Warfare must be allowed because human violence is instinctive.

Veganism is foolish because humans have eaten meat for thousands of years.

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.
Naturalistic fallacy – inferring evaluative conclusions from purely factual premises[49] in violation of fact–value distinction. For instance, inferring ought from is (sometimes referred to as the is-ought fallacy) is an instance of naturalistic fallacy. Also naturalistic fallacy in a stricter sense as defined in the section "Conditional or questionable fallacies" below is an instance of naturalistic fallacy. Naturalistic fallacy is the inverse of moralistic fallacy.
Naturalistic fallacy fallacy [50] (anti-naturalistic fallacy[51]) – inferring impossibility to infer any instance of ought from is from the general invalidity of is-ought fallacy, mentioned above. For instance, is {\displaystyle P\lor \neg P} P \lor \neg P does imply ought {\displaystyle P\lor \neg P} P \lor \neg P for any proposition {\displaystyle P} P, although the naturalistic fallacy fallacy would falsely declare such an inference invalid. Naturalistic fallacy fallacy is an instance of argument from fallacy.
Nirvana fallacy (perfect solution fallacy) – when solutions to problems are rejected because they are not perfect.
Onus probandi – from 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. Is the obligation on a party in a dispute to provide sufficient warrant for their position, it occurs when either a proposition is assumed to be true because it has not yet been proved false or a proposition is assumed to be false because it has not yet been proved true.
Post hoc ergo propter hoc Latin for "after this, therefore because of this" (faulty cause/effect, coincidental correlation, correlation without causation) – X happened, then Y happened; therefore X caused Y. The Loch Ness Monster has been seen in this loch. Something tipped our boat over; it's obviously the Loch Ness Monster.[52]
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, undesirable conclusion.
Psychologist's fallacy – occurs when an observer assumes that one's own subjective experience reflects the true nature of an event.
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.[53]
Referential fallacy[54] – 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 we use them.
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.
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.
Shotgun argumentation – the arguer offers such a large number of arguments for a position that the opponent can't possibly respond to all of them. (See "Argument by verbosity" and "Gish Gallop", above.)
Special pleading – where a proponent of a position attempts to cite something as an exemption to a generally accepted rule or principle without justifying the exemption.
Wrong direction – cause and effect are reversed. The cause is said to be the effect and vice versa.[55]
Faulty generalizations	
Faulty generalizations – 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.[56]
No true Man – makes a generalization true by changing the generalization to exclude a counterexample.[57]
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.[58]
Survivorship bias – when a small number of survivors 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.[59]
Hasty generalization (fallacy of insufficient statistics, fallacy of insufficient sample, fallacy of the lonely fact, leaping to a conclusion, hasty induction, secundum quid, converse accident) – basing a broad conclusion on a small sample.[60]
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.
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.[61]
Thought-terminating cliché – a commonly used phrase, sometimes passing as folk wisdom, used to quell cognitive dissonance, conceal lack of thought-entertainment, move on to other topics etc. but in any case, end the debate with a cliché—not a point.
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.[62][63][64]

Red herring – argument given in response to another argument, which is irrelevant and draws attention away from the subject of argument. See also irrelevant conclusion.

Ad hominem – attacking the arguer instead of the argument.
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.[65]
Abusive fallacy – a subtype of ad hominem that verbally abuses the opponent rather than arguing about the originally proposed argument.[66]
Appeal to motive – a subtype of ad hominem that dismisses an idea by questioning the motives of its proposer.
Tone policing – a subtype of ad hominem focusing on emotion behind a message rather than the message itself as a discrediting tactic.
Traitorous critic fallacy (ergo decedo) – a subtype of ad hominem where a critic's perceived affiliation is seen as the underlying reason for the criticism and the critic is asked to stay away from the issue altogether.
Appeal to authority (argumentum ad verecundiam) – where an assertion is deemed true because of the position or authority of the person asserting it.[67][68]
Appeal to accomplishment – where an assertion is deemed true or false based on the accomplishments of the proposer.[69]
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.[70]
Appeal to emotion – where an argument is made due to the manipulation of emotions, rather than the use of valid reasoning.[71]
Appeal to fear – a specific type of appeal to emotion where an argument is made by increasing fear and prejudice towards the opposing side[72][73]
Appeal to flattery – a specific type of appeal to emotion where an argument is made due to the use of flattery to gather support.[74]
Appeal to pity (argumentum ad misericordiam) – an argument attempts to induce pity to sway opponents.[75]
Appeal to ridicule – an argument is made by presenting the opponent's argument in a way that makes it appear ridiculous.[76][77]
Appeal to spite – a specific type of appeal to emotion where an argument is made through exploiting people's bitterness or spite towards an opposing party.[78]
Wishful thinking – a specific type of appeal to emotion where a decision is made according to what might be pleasing to imagine, rather than according to evidence or reason.[79]
Appeal to nature – wherein judgment is based solely on whether the subject of judgment is 'natural' or 'unnatural'.[80] (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) – where a proposal is claimed to be superior or better solely because it is new or modern.[81]
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.)[82]
Appeal to tradition (argumentum ad antiquitatem) – a conclusion supported solely because it has long been held to be true.[83]
Appeal to wealth (argumentum ad crumenam) – supporting a conclusion because the arguer is wealthy (or refuting because the arguer is poor).[84] (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.[85]
Argumentum ad populum (appeal to widespread belief, bandwagon argument, appeal to the majority, appeal to the people) – where a proposition is claimed to be true or good solely because many people believe it to be so.[86]
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.[87]
Bulverism (psychogenetic fallacy) – inferring why an argument is being used, associating it to some psychological reason, then assuming it is invalid as a result. It is wrong to assume that if the origin of an idea comes from a biased mind, then the idea itself must also be a falsehood.[45]
Chronological snobbery – where a thesis is deemed incorrect because it was commonly held when something else, clearly false, was also commonly held.[88][89]
Fallacy of relative privation ("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. For example, First World problem.
Genetic fallacy – where a conclusion is suggested based solely on something or someone's origin rather than its current meaning or context.[90]
Judgmental language – insulting or pejorative language to influence the recipient's judgment.

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.[91]
Naturalistic fallacy (is–ought fallacy,[92] naturalistic fallacy[93]) – claims about what ought to be on the basis of statements about what is.
Pooh-pooh – dismissing an argument perceived unworthy of serious consideration.[94]
Straw man fallacy – an argument based on misrepresentation of an opponent's position.[95]
The Sharpshooter fallacy – is committed when differences in data are ignored, but similarities are stressed. From this reasoning, a false conclusion is inferred.[1] This fallacy is the philosophical or rhetorical application of the multiple comparisons problem (in statistics) and apophenia (in cognitive psychology). It is related to the clustering illusion, which is the tendency in cognition to interpret patterns where none actually exist. The name comes from a joke about an individual who fires some gunshots at the side of a barn, then paints a target centered on the tightest cluster of hits and claims to be a sharpshooter.[2][3][4] The sharpshooter fallacy often arises when a person has a large amount of data at his or her disposal, but only focuses on a small subset of that data. 
Tu quoque ("you too", appeal to hypocrisy, I'm rubber and you're glue) – 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.[97]
Two wrongs make a right – occurs when it is assumed that if one wrong is committed, an "equal but opposite" wrong will cancel it out.[98]
Vacuous truth – A claim that is technically true but meaningless, in the form of claiming that no A in B has C, when there are 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".
Appeal to self-evident truth - A claim that a proposition is self-evidently true, so needs no further supporting evidence. If self-evidence is actually the basis for the claim, it is arbitrary and the opposite (a contradictory or contrary statement) is equally true. In many cases, however, the basis is really some kind of unstated and unexamined observation or assumption.

Conditional or questionable fallacies
	
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.[99]
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 (sometimes also taken to mean the appeal to nature) or God's will.[80]
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. (Example: If x does y then z would [probably] occur, leading to q, leading to w, leading to e.)[100] This is also related to the reductio ad absurdum.
