Dunning–Kruger effect. The Dunning–Kruger effect is a cognitive bias in which low-ability individuals suffer from illusory superiority, mistakenly assessing their ability as much higher than it really is.
Dunning and Kruger attributed this bias to a metacognitive incapacity, on the part of those with low ability, to recognize their ineptitude and evaluate their competence accurately. Their research also suggests corollaries: high-ability individuals may underestimate their relative competence and may erroneously assume that tasks which are easy for them are also easy for others. Dunning and Kruger have postulated that the effect is the result of internal illusion in those of low ability, and external misperception in those of high ability: "The miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others. 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. The term is also used popularly, often with subtly different meanings.
Causes 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. Psychoanalyst Richard Tuch suggests that Freud offered at least one alternative explanation for the Madonna–whore complex:
Forer effect. A related and more general phenomenon is that of subjective validation. 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 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. The sketch contains statements that are vague and general enough to most people.
