Illusory Superiority Effect Definition | Psychology

Illusory superiority is a theory in psychology where people tend to overestimate how superior they are to others in different facets of their lives.  Whether it’s how many friends you have, how kind of a person you are, or even how smart you are, we all tend to think we’re above average. The illusory superiority effect is also called the above-average effect, superiority bias, leniency error, sense of relative superiority, primus inter pares effect, and the Lake Wobegon effect.

Some people think its a form of self-preservation since we’re able to forget some of our failures and remember our successes, therefor helping our minds keep ourselves happier than we might otherwise be in reality.
