10 Facts About Intelligence quotient

An intelligence quotient is a total score derived from a set of standardized tests or subtests designed to assess human intelligence.

Intelligence quotient'storically, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.

Intelligence quotient hypothesized that there should exist a correlation between intelligence and other observable traits such as reflexes, muscle grip, and head size.

Intelligence quotient set up the first mental testing center in the world in 1882 and he published "Inquiries into Human Faculty and Its Development" in 1883, in which he set out his theories.

Intelligence quotient observed that children's school grades across seemingly unrelated school subjects were positively correlated, and reasoned that these correlations reflected the influence of an underlying general mental ability that entered into performance on all kinds of mental tests.

Intelligence quotient suggested that all mental performance could be conceptualized in terms of a single general ability factor and a large number of narrow task-specific ability factors.

Intelligence quotient believed that differences in a person's ability were acquired primarily through genetics and that eugenics could be implemented through selective breeding in order for the human race to improve in its overall quality, therefore allowing for humans to direct their own evolution.

Intelligence quotient quickly extended the use of the scale to the public schools, to immigration and to a court of law .

Intelligence quotient argued that "feeble-mindedness" was caused by heredity, and thus feeble-minded people should be prevented from giving birth, either by institutional isolation or sterilization surgeries.

Intelligence quotient asks whether it represents a real increase in intelligence beyond IQ scores.
