Fallacy Summary: Treat an authority’s word as proof.

Expertise can inform but cannot replace evidence; citing status bypasses critical evaluation. Research context: Informal-logic and argumentation research treats fallacies as structural problems in reasoning. A conclusion can sound persuasive while still being weak if the link between premises, evidence, and conclusion is not valid. Pattern-specific focus: Treat an authority’s word as proof. Practical review method: separate factual claims from interpretation, check source quality, and test whether the conclusion survives alternative explanations.

How to recognize appeal to authority yourself

• A rhetorical move replaces proof (for example, popularity, authority, or insult).
• Causation is claimed without ruling out alternatives or coincidence.
• The argument is reduced to an artificial either/or choice.
• Emotion is used to drive agreement where evidence should carry the burden.

Verification questions

• Which premise is doing the critical work, and is it actually supported?
• Does the conclusion logically follow, or does rhetoric bridge the gap?
• What alternative explanation would still fit the observed facts?
