'''IQ''' or '''intelligence quotient''' is a measure of a person's cognitive ability. IQ is measured with tests that contain cognitive tasks that are chosen to be as unrelated to culture and prior experience as possible. | '''IQ''' or '''intelligence quotient''' is a measure of a person's cognitive ability.

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 tasks. IQ has also been found to correlate with certain physiological measures, such as reaction time<ref>https://www.sciencedirect.com/science/article/abs/pii/S0160289601000629</ref>, brain volume,<ref>https://www.sciencedirect.com/science/article/abs/pii/S0160289616303385</ref> and color discrimation.<ref>https://www.sciencedirect.com/science/article/abs/pii/S0160289601000666</ref> This has lead to the conclusion that | 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 tasks.

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. This enables one to better find a solution or path to any given goal or solution to a problem. | 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.
