How to Use the Fallacy Finder Tool

The Fallacy Finder is a specialized tool designed to help you identify and understand logical fallacies in text.

Common Logical Fallacies

Here are some of the types of logical fallacies that this tool can detect in your pasted text.

1. Ad Hominem: Attacking the person making the argument rather than the argument itself.
2. Straw Man: Misrepresenting someone’s argument to make it easier to attack.
3. Appeal to Ignorance (Argumentum ad Ignorantiam): Claiming something is true because it has not been proven false, or vice versa.
4. False Dilemma/False Dichotomy: Presenting two opposing options as the only possibilities when more exist.
5. Slippery Slope: Arguing that a small first step will lead to a chain of related events culminating in some significant effect.
6. Circular Reasoning (Begging the Question): When the conclusion of an argument is assumed in the phrasing of the question itself.
7. Hasty Generalization: Making a rushed conclusion without considering all of the variables.
8. Red Herring: Diverting the attention of the audience from the matter at hand to a different issue.
9. Post Hoc Ergo Propter Hoc: Assuming that because one event followed another, the first caused the second.
10. Appeal to Authority (Argumentum ad Verecundiam): Suggesting that because an authority figure believes something, it must therefore be true.
11. Appeal to Emotion: Manipulating an emotional response in place of a valid or compelling argument.
12. Bandwagon Fallacy: Arguing that because everyone else believes something or is doing something, it must be valid or correct.
13. No True Scotsman: Making an appeal to purity as a way to dismiss relevant criticisms or flaws of an argument.
14. Equivocation: Using an ambiguous term in more than one sense, thus making an argument misleading.
15. Appeal to Tradition: Arguing that a practice or thing is right because it has always been done that way.
16. Loaded Question: Asking a question that contains an unjustified assumption.
17. Guilt by Association: Discrediting an argument for proposing an idea that is shared by some socially demonized individual or group.
18. The Gambler’s Fallacy: Believing that ‘runs’ occur to statistically independent phenomena such as roulette wheel spins.

These are just a few examples of the many types of fallacies that can be present in arguments. By identifying and understanding these fallacies, one can critically evaluate the strength of arguments and avoid common pitfalls in reasoning.
