An ad hominem fallacy attacks a person's character instead of addressing their argument.

Why it is a fallacy

A claim needs evidence that connects the reasons to the conclusion. This fallacy skips that connection or replaces it with a shortcut.

Examples

  • We shouldn't trust her proposal because she is arrogant.
  • His idea is wrong because he's not a real expert.
  • Don't listen to them, they failed before.

How to respond

  • Separate the person from the claim and ask for evidence.
  • Redirect the conversation to the actual argument.
  • Ask which premise is incorrect rather than who is speaking.
