Confirmation Bias

The tendency to privilege evidence that fits prior expectations.

Direct answer

Confirmation bias is the tendency to seek, notice, interpret, or emphasize evidence that supports prior expectations while discounting or failing to seek contradictory evidence.

Mechanism

How it works

  1. 01

    Existing beliefs influence what information is searched for and what receives attention.

  2. 02

    Interpretation can preserve a prior model even when ambiguous evidence would support several alternatives.

  3. 03

    Social and algorithmic environments can amplify selective exposure.

Consequence

Why it matters

  1. 01

    A system can feel increasingly certain while its evidence set becomes narrower.

  2. 02

    Explicit alternative-generation can protect against premature closure.
