Every Logical Fallacy Explained in 11 Minutes

Summary

The video is a rapid glossary of logical fallacies: common errors in reasoning or debate. It emphasizes that people can make these mistakes by attacking a speaker instead of an argument, drawing conclusions from weak evidence, distorting a position, or using misleading definitions and comparisons.

Spotting a fallacy can show that an argument is poorly supported, but—as the fallacy fallacy warns—it does not automatically prove the conclusion false.

Fallacies covered

Attacking, evading, or misrepresenting an argument

• Ad hominem: Attacks a person rather than addressing their argument.
• Tu quoque: Responds to a claim by accusing its speaker of hypocrisy instead of answering the claim.
• Circumstantial ad hominem: Treats a person’s possible interests or circumstances as proof that their conclusion is wrong.
• Tone policing: Discredits a message by focusing on the speaker’s emotional tone rather than the substance.
• Bulverism: Assumes an argument is wrong because of who made it, rather than examining its reasoning.
• Association fallacy: Assumes two things share properties simply because they belong to the same group.
• Appeal to accomplishment: Treats a claim as true or false based on the proposer’s achievements.
• Courtier’s reply: Dismisses a critic on the grounds that they lack sufficient expertise or credentials.
• Appeal to the stone: Calls an argument absurd or ridiculous without explaining why.
• Red herring: Diverts attention from the relevant issue.
• Straw man: Misrepresents someone’s argument to make it easier to refute.
• Ignoratio elenchi (missing the point): Gives an argument that does not address the question at issue.
• Thought-terminating cliché: Uses a familiar saying or slogan to shut down further discussion.
• Loaded question: Poses a question that embeds an assumption the respondent has not accepted.
• Burden of proof fallacy: Evades the responsibility to support a claim; the person making a claim generally bears that burden.

Weak evidence, faulty inference, and causation

• Hasty generalization: Draws a broad conclusion from too few examples.
• Anecdotal fallacy: Uses limited personal experience to support a sweeping conclusion.
• Texas sharpshooter fallacy: Selects patterns or data after the fact to make a conclusion appear supported, while ignoring randomness or contrary evidence.
• Cherry-picking: Highlights supportive examples or data while ignoring relevant counterevidence.
• Appeal to authority: Treats an influential person’s opinion as sufficient evidence that a claim is true.
• Appeal to ignorance: Claims something is true because it has not been disproved, or false because it has not been proved.
• Proof by assertion: Repeats a claim as if repetition made it true, even when it is challenged.
• False cause: Concludes that one thing caused another without adequate evidence, often from correlation alone.
• Fallacy of the single cause: Explains an outcome by one simple cause when several factors may have contributed.
• Affirming the consequent: From “if A, then B” and “B,” incorrectly concludes “A.”
• Denying the antecedent: From “if A, then B” and “not A,” incorrectly concludes “not B.”
• Appeal to emotion: Uses emotional pressure in place of adequate factual support.
• Appeal to consequences: Judges a claim’s truth by whether its consequences would be desirable or undesirable.

Distorted choices, comparisons, and definitions

• False dilemma: Presents only two options when more exist, or wrongly treats them as mutually exclusive.
• Suppressed correlative: Defines one of two supposed alternatives so broadly that it absorbs the other.
• Affirming a disjunct: Treats an “either/or” as exclusive and concludes that one option rules out the other, even when both could be true.
• Middle-ground fallacy: Assumes the truth must lie between two opposing positions.
• Faulty analogy: Assumes two things are alike in important ways because they resemble each other in one respect.
• False equivalence: Treats two subjects as equivalent on the basis of flawed reasoning.
• Incomplete comparison: Makes a comparative claim without saying what it is being compared with or on what basis.
• Continuum fallacy: Claims that two states cannot be distinguished because there is a gradual range between them.
• Ambiguity fallacy: Relies on unclear wording or multiple possible meanings.
• Equivocation: Uses an ambiguous word or phrase in different senses within the same argument.
• Definist fallacy: Defines a term in a way that makes the speaker’s position easier to defend.
• Genetic fallacy: Accepts or rejects a claim solely because of where it came from.
• Etymological fallacy: Assumes a word’s oldest or original meaning is its true meaning.
• Quoting out of context: Removes a statement from its surrounding context in a way that distorts its intended meaning.
• Reification fallacy: Treats an abstract idea as if it were a concrete, intentional thing.
• Vacuous truth: Makes a technically true but uninformative claim because there are no relevant cases—for example, saying no phones in a room are on when there are no phones in the room.

Generalizations and group reasoning

• Composition fallacy: Assumes what is true of some parts must be true of the whole.
• Division fallacy: Assumes what is true of a whole must also be true of its parts.
• Ecological fallacy: Assumes what is true of a population must be true of each individual in it.
• No True Scotsman: Protects a generalization by excluding counterexamples as not genuine members of the group.
• Special pleading: Applies a rule to others but exempts oneself or a favored case without adequate justification.

Tradition, ideals, and judgment

• Appeal to nature: Assumes that what is natural is good, or what is unnatural is bad.
• Appeal to tradition: Treats a practice as correct because it has been followed for a long time.
• Appeal to novelty: Assumes something is better simply because it is new or modern.
• Chronological snobbery: Assumes modern ideas are superior to older ones just because they are modern.
• Sunk cost fallacy: Continues an undertaking because of past investment, even when future costs outweigh likely benefits.
• Moralistic fallacy: Infers what is true about the world from what one believes ought to be true.
• Nirvana fallacy: Rejects a realistic solution because it falls short of an ideal or perfect one.
• Ludic fallacy: Mistakes the structured uncertainty of games for the more complex uncertainty of real life.
• Historian’s fallacy: Assumes people in the past had the same information and perspective available to later observers.
• Inflation of conflict: Exaggerates disagreement within a field to undermine claims made in that field.
• Retrospective determinism: Treats an outcome as inevitable simply because it happened under the circumstances that preceded it.
• Personal incredulity: Assumes a claim cannot be true because it is difficult to understand or imagine.
• Psychologist’s fallacy: Assumes an observer’s subjective experience reflects the true nature of an event.
• “I’m entitled to my opinion” fallacy: Uses the right to hold an opinion as a substitute for addressing objections to it.
• Two wrongs make a right: Answers an accusation of wrongdoing with a similar accusation.
• Fallacy fallacy: Assumes a conclusion must be false simply because an argument for it contains a fallacy.
