'''IQ''' or intelligence quotient is a person's | '''IQ''' or '''intelligence quotient''' is a measure of a person's ability, separate from common sense. IQ is measured with tests that contain cognitive tasks that are chosen to be as unrelated to culture and prior experience as possible. | ||
It turns out that performance on different IQ tests correlates somewhat (r = ~0.5) which means each human has a certain amount of ''general intelligence'' that largely determines their ability to act intelligently in ''all'' cognitive task. | |||
Abilities that are relevant for all cognitive tasks are for example to quickly learn, store, and process a maximal amount of information and quickly run through different hypotheses without losing track of things. | |||
Colloquially, "IQ" is used synonymously with high general intelligence. | |||
Even real-life cognitive tasks like school, work performance and even social skills are just as much correlated with IQs, so IQ can tell us a lot about people's overall performance. It is an imperfect measure, but it allows to decide about extremes very reliably, e.g. a person with . An entire battery of at least three tests is necessary to assess general intelligence accurately.<ref>https://www.telegraph.co.uk/news/science/science-news/9755929/IQ-tests-do-not-reflect-intelligence.html</ref> | |||
