Draws a causal conclusion without sufficient evidence, often from mere correlation or sequence.

Quick summary
  • Definition: Draws a causal conclusion without sufficient evidence, often from mere correlation or sequence.

  • Identify: Look for patterns like Notice a relationship or sequence between A and B.

What is the False Cause fallacy?

False cause is a parent label for causal missteps where relationships are asserted without ruling out confounders, coincidence, or reversed direction. Specific forms include post hoc, cum hoc, and spurious correlation.

People lean on this pattern because Humans seek patterns and explanations; quick causal stories are persuasive even when premature.

The Pattern
  • 1Notice a relationship or sequence between A and B.
  • 2Infer causation without testing alternatives.
  • 3Ignore confounders, mechanisms, or control comparisons.

Why the False Cause fallacy matters

This fallacy distorts reasoning by Correlation or sequence alone does not establish causation. Without evidence, the causal claim is speculative.. It often shows up in contexts like Policy evaluation, Everyday reasoning, Marketing, where quick takes and ambiguity can hide weak arguments.

Recognition

  • Causal language based only on timing or co-movement.
  • No discussion of confounders or alternative causes.
  • Mechanisms are absent or weak.

Response

  • Ask for evidence ruling out other causes.
  • Request mechanism and controlled comparisons.
  • Rephrase as a hypothesis pending validation.
