Confirmation Bias
We seek, interpret, and remember information that confirms our existing beliefs while ignoring contradictory evidence.
Your brain is a belief-defending machine. Once you form an opinion, you filter reality to support it—noticing whatever agrees with you, dismissing the rest as biased.
This is why two people can watch the same debate and both believe their side won. Each cherry-picks the moments that fit.
Social media algorithms exploit this, feeding you what you already agree with. Echo chambers make opposing views seem rare or extreme.
Confirmation Bias
"It is the mark of an educated mind to be able to entertain a thought without accepting it." – Aristotle
Actively seek opposing views
Deliberately read people who disagree with you—their best arguments, not strawman versions.
- Follow diverse perspectives
- Read opposing opinions first
- Steelman, don't strawman
Ask disconfirming questions
Ask: 'What evidence would change my mind?' If the answer is 'nothing,' you're rationalizing.
Track your predictions
Write down predictions before events happen, then review them. Accountability reveals biased thinking.
Clear thinking starts with knowing your brain distorts reality to protect your beliefs.
