Better-Than-Average Effect / 优于常人效应

Better-than-average effect is the tendency to believe oneself more capable, rational, humorous, logical, or bias-resistant than ordinary people. 123.人性实验：当心你自己！ connects this to the everyday language of false confidence and to studies where people with higher test scores or stronger self-images still failed to avoid perception bias.

The episode’s warning is blunt: thinking that one is unusually rational can itself become a bias amplifier. The people most vulnerable to a distortion may be exactly the people who feel least vulnerable to it.

Key Claims
