Illusory Superiority

Description

From the Wikipedia:

"Illusory superiority (also known as better-than-average effect) is a cognitive bias in which people overestimate the degree to which they possess desirable qualities, relative to others, or underestimate their negative qualities relative to others. It is one of a class of positive illusions. Whereas in optimism bias people overestimate the likelihood of favorable events happening to them, in illusory superiority people have inflated views of their own characteristics.

The effect has been found when people compare themselves to others on many different abilities and personality traits. Some surveys have found all, or nearly all, the participants rating themselves as above the group average." (http://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect)
