A false analogy compares two things that are not similar in the ways that matter.

A false analogy compares two things that are not similar in the ways that matter.

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

  • Running a country is like running a family, so the same rules apply.
  • Employees are like nails; you have to hit them to make them work.
  • The brain is like a computer, so it must work the same way.

How to respond

  • Identify which similarities actually matter to the conclusion.
  • Point out key differences the analogy ignores.
  • Ask for evidence beyond the comparison.
