Dunning-Kruger effect


Simply put, the Dunning-Kruger effect is that dumb people tend to think they're much smarter than they actually are.

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

Also notable is that truly competent people tend to underestimate how smart they are.
