Dunning–Kruger effect. Cognitive bias about one's own skill The Dunning–Kruger effect is a cognitive bias in which people with limited competence in a particular domain overestimate their abilities. Some researchers also include the opposite effect for high performers: their tendency to underestimate their skills. In popular culture, the Dunning–Kruger effect is often misunderstood as a claim about general overconfidence of people with low intelligence instead of specific overconfidence of people unskilled at a particular task. The Dunning–Kruger effect is usually measured by comparing self-assessment with objective performance. For example, participants may take a quiz and estimate their performance afterward, which is then compared to their actual results. There are disagreements about what causes the Dunning–Kruger effect. There are disagreements about the Dunning–Kruger effect's magnitude and practical consequences.
Definition[edit] David Dunning Measurement, analysis, and investigated tasks[edit] [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.
In popular culture[edit] See also[edit] References[edit] Notes Literature John A. Forer effect. 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".
