The Dunning-Kruger Effect

The Dunning-Kruger effect:

The Dunning-Kruger effect is the phenomenon whereby people who have little knowledge systematically think that they know more than others who have much more knowledge.

Across 4 studies, the authors found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although test scores put them in the 12th percentile, they estimated themselves to be in the 62nd.
