75+ Logical Fallacy Examples

Logical fallacies are common errors in reasoning that undermine the logic of an argument. Understanding these fallacies is crucial for clear, persuasive, and logical communication. This article will provide a step-by-step guide on how to identify and use logical fallacies, with examples and FAQs to help you navigate this complex topic.

What is a Logical Fallacy?

A logical fallacy is a flaw in reasoning that leads to invalid arguments. These errors often occur in debates and arguments, where they can be used intentionally or unintentionally to persuade or manipulate an audience. Logical fallacies can range from simple bias examples to more complex rhetorical devices.

Types of/ Common Logical Fallacies

Logical fallacies are errors in reasoning that undermine the logic of an argument. They can be either formal (related to the structure of the argument) or informal (related to the content of the argument). Understanding different types of logical fallacies can help you identify weak arguments and improve your own reasoning skills.

1. Ad Hominem

An ad hominem fallacy attacks the person making the argument rather than the argument itself. This is often used to discredit the opponent.

Example: “You can’t trust John’s opinion on climate change because he’s not a scientist.”

2. Straw Man

A straw man fallacy occurs when someone misrepresents or oversimplifies an opponent’s argument to make it easier to attack.

Example: “Vegetarians say that no one should eat meat, but that would mean everyone would miss out on essential nutrients.”

3. Appeal to Ignorance (Argumentum ad Ignorantiam)

This fallacy asserts that a proposition is true because it has not yet been proven false, or vice versa.

Example: “No one has ever proven that UFOs don’t exist, so they must be real.”

4. False Dilemma (False Dichotomy)

A false dilemma fallacy presents only two options or sides when there are actually more available.

Example: “You’re either with us, or you’re against us.”

5. Slippery Slope

The slippery slope fallacy argues that a relatively small first step inevitably leads to a chain of related events culminating in a significant (usually negative) effect.

Example: “If we allow students to redo assignments for a better grade, next they’ll want to retake exams, and eventually, they’ll expect to get their degree without any effort.”

6. Circular Reasoning (Begging the Question)

Circular reasoning occurs when the conclusion of an argument is used as a premise of the same argument.

Example: “I’m trustworthy because I always tell the truth.”

7. Hasty Generalization

A hasty generalization fallacy occurs when a conclusion is reached based on insufficient or biased evidence.

Example: “My two neighbors are loud, so everyone in this neighborhood must be noisy.”

8. Red Herring

A red herring fallacy involves diverting attention from the real issue by focusing on an irrelevant issue.

Example: “Why worry about the environment when there are so many homeless people who need help?”

9. Bandwagon (Ad Populum)

The bandwagon fallacy argues that one must accept or reject an argument because everyone else is doing so.

Example: “Everyone is buying the latest smartphone, so it must be the best one available.”

10. Appeal to Authority (Argumentum ad Verecundiam)

This fallacy occurs when an argument is deemed true or false based on the authority of someone who supports it, rather than the evidence.

Example: “This dietary supplement must be effective because a famous actor uses it.”

11. Post Hoc Ergo Propter Hoc (False Cause)

This fallacy assumes that if one event happens after another, then the first event must have caused the second.

Example: “I wore my lucky shirt, and then I passed my exam. Therefore, the shirt made me pass.”

12. Appeal to Emotion

This fallacy manipulates an emotional response in place of a valid or compelling argument.

Example: “Think of the children! We must ban all violent video games.”

13. Equivocation

Equivocation occurs when a word with multiple meanings is used ambiguously in an argument, misleading the audience.

Example: “The sign said ‘fine for parking here,’ so I thought it was okay to park.”

14. Non Sequitur

A non sequitur is an argument where the conclusion does not logically follow from the premises.

Example: “She drives a BMW, so she must be wealthy.”

15. Appeal to Tradition

This fallacy argues that something is better or correct simply because it is older, traditional, or has always been done that way.

Example: “We shouldn’t change the curriculum because it has always been like this.”
