The false cause fallacy assumes a causal relationship without adequate evidence.

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

  • We rebranded and then sales dropped, so the rebrand caused it.
  • I took vitamins and got better, so the vitamins cured me.
  • After the new manager arrived, productivity rose, so she caused it.

How to respond

  • Ask for a causal mechanism and additional evidence.
  • Consider confounding variables and alternative explanations.
  • Look for controlled comparisons or repeated patterns.
