social cognition

You value information simply because a successful person said it.

Prestige bias is the tendency to assign greater weight to the opinions of people who are high-status, regardless of their expertise in the specific topic.

You use social status as a mental shortcut to identify reliable information. Because successful individuals are culturally visible, your mind defaults to assuming their success in one domain—like business—transferably grants them wisdom in every other domain.

You confuse fame with accuracy every single day.

Confidence
Solid, with limits
