What Is a Logical Fallacy?
A logical fallacy is an error in reasoning that makes an argument invalid or misleading. The conclusion may feel persuasive, but the logical connection between evidence and conclusion is broken. Recognizing fallacies helps you write stronger arguments and evaluate others' claims more critically.
Categories of Logical Fallacies
Formal Fallacies
Formal fallacies have errors in the logical structure itself. The argument's form is invalid regardless of the content. Examples include affirming the consequent ("If it rains, the ground is wet; the ground is wet, so it rained") and denying the antecedent.
Informal Fallacies
Informal fallacies have errors in the content, context, or delivery of the argument. The logical form may look correct, but the reasoning fails due to irrelevant evidence, emotional manipulation, or misleading language. Most everyday fallacies fall into this category.
Most Common Fallacies in Writing
- Ad hominem: attacking the person instead of their argument
- Straw man: misrepresenting an opponent's position to make it easier to attack
- False dichotomy: presenting only two options when more exist
- Appeal to authority: citing an authority figure as proof without relevant expertise
- Circular reasoning: using the conclusion as a premise
- Slippery slope: claiming one action will inevitably lead to extreme consequences
- Red herring: introducing irrelevant topics to divert attention
