Genetic Fallacy

Judges a claim true or false based solely on its source or origin rather than its merits.

Quick summary
  • Definition: Judges a claim true or false based solely on its source or origin rather than its merits.
  • Impact: Genetic Fallacy distorts reasoning by Truth depends on evidence and reasoning, not solely on origin. Good ideas can come from suspect sources and vice versa.
  • Identify: Look for patterns like Note the source or origin of a claim.

What is the Genetic Fallacy?

The genetic fallacy accepts or rejects a claim because of where it came from—who said it, where it was published, or how it originated—instead of examining the evidence or reasoning. Origins can inform credibility but do not determine truth.

People lean on this pattern because Source cues are fast heuristics; discrediting origins is an easy shortcut to avoid engagement with substance.

The Pattern
  • 1Note the source or origin of a claim.
  • 2Accept or reject the claim because of that origin.
  • 3Skip evaluating the actual evidence or logic.

Why the Genetic Fallacy fallacy matters

This fallacy distorts reasoning by Truth depends on evidence and reasoning, not solely on origin. Good ideas can come from suspect sources and vice versa.. It often shows up in contexts like Debate, Media, Workplace, where quick takes and ambiguity can hide weak arguments.

Examples of Genetic Fallacy in Everyday Life
