The Dunning–Kruger effect is a cognitive bias that describes the systematic tendency of people with low ability in a specific area to give overly positive assessments of this ability. The term may also refer to the tendency of high performers to underestimate their skills. The effect was formalized and empirically studied by the psychologists David Dunning and Justin Kruger in 1999. In popular culture, the Dunning–Kruger effect is sometimes misunderstood as claiming that people with low intelligence are generally overconfident, instead of denoting specific overconfidence of people unskilled at particular areas.
