Dunning–Kruger effect. Cognitive bias about one's own skill 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. It was first identified 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. The Dunning–Kruger effect has been demonstrated across multiple studies in a wide range of tasks from fields such as business, politics, medicine, driving, aviation, spatial memory, examinations in school, and literacy. A number of explanations for, and criticisms of, the Dunning–Kruger effect have been proposed.

Measurement, analysis, and investigated tasks [edit] How people become monsters ... or heroes | Madonna–whore complex. In sexual politics the view of women as either Madonnas or whores limits women's sexual expression, offering two mutually exclusive ways to construct a sexual identity.[4] The term is also used popularly, often with subtly different meanings. Causes[edit] Freud argued that the Madonna–whore complex is caused by oedipal castration fears which arise when a man experiences the affection he once felt for his mother with women he now sexually desires.

In order to manage this anxiety, the man categorizes women into two groups: women he can admire and women he finds sexually attractive. Whereas the man loves women in the former category, he despises and devalues the latter group.[5] Psychoanalyst Richard Tuch suggests that Freud offered at least one alternative explanation for the Madonna–whore complex: According to Freudian psychology, this complex often develops when the sufferer is raised by a cold and distant mother.

A related and more general phenomenon is that of subjective validation.[1] Subjective validation occurs when two unrelated or even random events are perceived to be related because a belief, expectation, or hypothesis demands a relationship.

Thus people seek a correspondence between their perception of their personality and the contents of a horoscope. Forer's demonstration[edit] On average, the students rated its accuracy as 4.26 on a scale of 0 (very poor) to 5 (excellent). Only after the ratings were turned in was it revealed that each student had received an identical sketch assembled by Forer from a newsstand astrology book.[2] The sketch contains statements that are vague and general enough to most people. In another study examining the Forer effect, students took the MMPI personality assessment and researchers evaluated their responses. The Forer effect is also known as the "Barnum effect".
