Cheat Sheet

  1. Ad Hominem Attack -

    This fallacy targets the person instead of the argument, for example, "You're just a student, so your opinion doesn't count." A handy mnemonic is "Aim at the Argument, Not the Attacker." According to Purdue OWL, avoiding ad hominem keeps discussions focused on evidence, not insults.

  2. Slippery Slope Fallacy -

    This error assumes one small step will inevitably lead to extreme consequences (e.g., "If we allow A, then Z will happen"). Think "one slide, endless fall" to remember it. The Stanford Encyclopedia of Philosophy warns that without proof of the causal chain, it's just fear-mongering.

  3. Straw Man Fallacy -

    This involves misrepresenting an opponent's argument to make it easier to attack, such as exaggerating "They want minor tax cuts" into "They want to destroy public services." Use the "rebuild the real man" tip: always check the original claim. Harvard's critical thinking resources stress that fair representation leads to genuine debate.

  4. Appeal to Authority -

    This fallacy assumes a claim is true because an authority figure said so, for instance, "Famous scientist X endorses this diet, so it must work." Remember "expertise isn't proof" unless backed by data. The University of North Carolina's writing center advises verifying authority claims with peer-reviewed research.

  5. False Dilemma (Either/Or) -

    This fallacy presents only two extreme options, like "You're either for us or against us," ignoring middle ground. A simple trick is the "many paths" reminder to spot excluded alternatives. Academic journals note that recognizing additional possibilities strengthens logical analysis.
