Logical Fallacies Examples, Logical fallacies worksheet with answers pdf
| Fallacy | Definition | Example | Counterargument |
|---|---|---|---|
| Ad hominem | Attacking the person making the argument rather than the argument itself. | “You’re just saying that because you’re a liberal.” | The person’s political affiliation is irrelevant to the validity of the argument. |
| Straw man | Misrepresenting the opponent’s argument to make it easier to attack. | “You’re saying that we should abolish all taxes. That’s ridiculous!” | The opponent may not have actually said that we should abolish all taxes. |
| Begging the question | Assuming the truth of the conclusion in the premises. | “God exists because the Bible says so.” | The Bible is not an independent source of evidence for the existence of God. |
| Circular reasoning | Using the conclusion to support the premises. | “I know that this is true because I feel it in my heart.” | Feelings are not a reliable source of evidence. |
| False dichotomy | Presenting only two options when there are more than two. | “Either you’re with us or you’re against us.” | There may be other options that are not being considered. |
| Slippery slope | Claiming that one event will inevitably lead to a series of other events, even though there is no evidence to support this claim. | “If we legalize same-sex marriage, then next thing you know, we’ll be legalizing bestiality.” | There is no evidence to support this claim. |
| Hasty generalization | Making a generalization based on a small sample size. | “All men are cheaters.” | This generalization is based on a small sample size and is not representative of all men. |
| Appeal to ignorance | Claiming that something is true because it has not been proven false. | “There is no evidence that ghosts don’t exist.” | The lack of evidence does not prove that ghosts exist. |
| Appeal to emotion | Using emotions to persuade rather than logic. | “You should vote for me because I’m the only candidate who cares about the poor.” | The candidate’s concern for the poor does not necessarily mean that they are the best candidate for the job. |
| Appeal to authority | Using the authority of an expert to support an argument, even though the expert is not an expert in the field. | “My doctor told me that vaccines are dangerous.” | The doctor is not an expert in vaccines and their safety. |
