Confirmation Bias

The tendency to search for, interpret, favor, and recall information in a way that confirms one’s preexisting beliefs or hypotheses, while giving disproportionately less consideration to alternative possibilities.

Examples

  • Seeking out news sources that align with your political views
  • Interpreting ambiguous evidence as supporting your existing position
  • Remembering hits and forgetting misses when evaluating a belief

Why It Happens

The brain prefers consistency and reduces cognitive load by favoring information that fits existing mental models. Challenging one’s beliefs requires more mental effort.

How to Counteract

  • Actively seek disconfirming evidence
  • Play devil’s advocate with your own views
  • Ask “What would change my mind?”
