Confirmation Bias and Motivated Reasoning
Understand how cognitive biases affect our ability to evaluate information objectively.
Your brain uses mental shortcuts (heuristics) to process information quickly. These shortcuts are usually helpful, but they can also lead to systematic errors in thinking called cognitive biases.
Confirmation Bias
Confirmation bias is the tendency to search for, interpret, and remember information in a way that confirms your existing beliefs. We all have it. It means we are more likely to accept information that agrees with us and more likely to scrutinize information that challenges us.
Motivated Reasoning
Motivated reasoning is when we use our reasoning abilities not to find the truth, but to justify a conclusion we have already reached. We become lawyers for our existing beliefs rather than judges evaluating evidence.
Overcoming Cognitive Biases
- Actively seek out information that challenges your views
- Ask: "What would change my mind about this?"
- Consider the strongest version of opposing arguments (steelmanning)
- Be especially skeptical of information that confirms what you already believe
- Slow down when you feel certain — certainty is often a sign of bias
