Common logical fallacies

Patterns of reasoning that look persuasive but don't hold.

Fallacies reviewers look for

  • Non sequitur: a conclusion that doesn't follow from its premises.
  • Straw man: rebutting a distorted version of a claim instead of the claim itself.
  • Ad hominem: attacking the person making a claim rather than the claim.
  • Appeal to authority: treating a claim as true because of who said it, not the evidence.
  • False dilemma: presenting two options as the only possibilities when others exist.
  • Circular reasoning: using the conclusion as one of its own premises.
  • Hasty generalization: drawing a broad conclusion from too little evidence.
  • Red herring: introducing an irrelevant point to distract from the question.
