belief

You filter reality to fit what you already know.

Humans systematically favor information that confirms their existing beliefs.

You not only seek out confirming evidence but also interpret ambiguous information in a way that supports your viewpoint. Your brain views conflicting data as a threat to your current model of the world. It is easier to ignore reality than to update your framework.

You are likely protecting your identity, not just your opinion.
