David Dunning
American social psychologist and professor of psychology
David Alan Dunning (born 1960) is an American social psychologist and professor of psychology at the University of Michigan. He is a retired professor of psychology at Cornell University.
Education
He received his B.A. from Michigan State University in 1982 and a Ph.D. from Stanford University in 1986, both in psychology.
Research
Dunning has published more than 80 peer-reviewed papers, book chapters, and commentaries. He is well known for co-authoring a 1999 study with graduate student Justin Kruger after reading about the 1995 Greater Pittsburgh bank robberies in which the perpetrators wore lemon juice instead of masks, thinking it would make them invisible to security cameras. This study showed that people who performed the lowest at certain tasks, such as judging humor, grammar, and logic, significantly overestimated how good they were at these tasks. This study has since given rise to what is known as the Dunning–Kruger effect, a cognitive bias in which people mistakenly assess their cognitive ability as greater than it is. The study also found that people who performed slightly above average at identifying how funny a given joke was tended to be the most accurate at assessing how good they were at the assigned tasks, and that those who performed the best tended to think they performed only slightly above average. In 2012, Dunning told Ars Technica that he "thought the paper would never be published" and that he was "struck just with how long and how much this idea has gone viral in so many areas."
Positions
Dunning is the executive officer of the Society for Personality and Social Psychology and the Foundation for Personality and Social Psychology. He has also served as an associate editor of the Journal of Personality and Social Psychology.

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q24238924. VIAF identifies the subject as 58475988. The Library of Congress control number is n2004108459. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
