Abstract

Many studies have shown that people display an apparent overconfidence. In particular, it is common for a majority of people to describe themselves as better-than-average. The literature takes for granted that this better-than-average effect is problematic. We argue, however, that, even accepting these studies on their own terms, there is nothing at all wrong with a strict majority of people rating themselves above the median.
