Dunning-Kruger Effect Quiz – Unskilled and Unaware

The Dunning-Kruger effect describes how people with low ability in an area often overestimate their competence. David Dunning and Justin Kruger of Cornell University published the study in 1999.

Participants took tests of humor, logic and grammar. Those in the bottom quarter, scoring around the 12th percentile, guessed they were around the 62nd. Top performers slightly underestimated themselves. The authors linked this to metacognition.

Dunning said a 1995 bank robber who used lemon juice to hide from cameras inspired the work. The paper won an Ig Nobel Prize in 2000. The popular Mount Stupid graph is an internet meme, and some researchers argue statistical effects explain part of the pattern.
