Confirmation Bias

Social-cognitive bias

Definition

The tendency to search for, interpret, and recall information in a way that confirms your pre-existing beliefs, while ignoring contradictory evidence.

Why it happens

Our brains are wired for efficiency. Processing information that aligns with existing beliefs requires less cognitive effort than challenging them. It also protects our sense of identity and worldview.

Real-life examples

Only reading news sources that align with your political views.
Remembering the times a horoscope was right and forgetting when it was wrong.
A manager only noticing evidence that supports their first impression of an employee.

How to counter it

Pause and identify your current belief about the topic.
Deliberately search for evidence that contradicts your view.
Discuss the issue with someone who holds the opposite opinion.
Write down both supporting and opposing evidence before deciding.

Quick tips

Actively seek out opposing viewpoints before forming an opinion.
Ask yourself: 'What evidence would change my mind?'
Discuss important decisions with people who think differently than you.
Keep a decision journal to track your reasoning over time.
