Logical fallacies

Ad Hominem

An attack on the person making an argument rather than the argument itself. For example, instead of debating a policy, one might say, 'How can you trust his opinion on environmental issues when he doesn't recycle?'

Appeal to Doubtful Authority

Supporting an argument by citing someone who lacks the credibility to speak on the issue. For example, claiming that a celebrity's opinion on a medical treatment is valid, despite them having no medical training.

Ad Populum (Bandwagon Appeal)

Arguing that something is true or right because it is popular. An example is saying, 'Everyone is voting for this candidate, so he must be the best choice for president.'

Begging the Question

Assuming the truth of the conclusion within the premise of the argument. For instance, 'The defendant is guilty because he committed the crime.' This argument presupposes guilt without proof.

Circular Argument

Restating the argument instead of providing evidence. An example is, 'The law is the law because it is legislated,' which doesn't clarify the reasons behind the law.

Equivocation

Using a word with multiple meanings ambiguously to mislead. For example, using the word 'light' to refer both to illumination and to something being not heavy, leading to confusion.

False Dilemma (Either/Or Fallacy)

Presenting only two options when more exist. For example, asserting 'You're either with us or against us' disregards neutral positions.

Faulty Analogy

Comparing two things that are not sufficiently alike. For example, suggesting that employees are like nails, needing to be hit on the head to work.

Genetic Fallacy

Judging something based on its origin rather than its current meaning or value. For instance, dismissing a scientific study because it was conducted by a government agency.

Hasty Generalization

Drawing a conclusion based on insufficient evidence. For example, concluding that all dogs are aggressive after being bitten by one dog.

Misleading Statistics

Using statistical data in a way that misrepresents or distorts the truth. An example could be stating that '70% of people prefer brand A' without clarifying the sample size or context.

Non Sequitur

A conclusion that does not logically follow from the premises. For example, 'She's wearing red shoes, so she must be a great leader.' This statement lacks logical connection.

Post Hoc Ergo Propter Hoc (False Cause)

Assuming that because one event followed another, the first caused the second. For instance, 'I wore my lucky shirt, and we won the game, so the shirt made us win.'

Red Herring

Introducing irrelevant information to distract from the main issue. For example, during a debate about climate change, one might say, 'What about all the jobs lost in the coal industry?'

Slippery Slope

Arguing that one small action will lead to a chain of significant negative events. For example, 'If we allow students to redo tests, soon they'll expect to redo every assignment.'

Straw Man

Misrepresenting someone’s argument to make it easier to attack. For instance, 'My opponent wants to cut military spending, which means he wants to leave us unprotected.'

Tu Quoque (You Too Fallacy)

Dismissing an argument by pointing out the opponent’s hypocrisy. For instance, saying 'You can't tell me to exercise when you don't work out yourself.'
