'''IQ''' or '''intelligence quotient''' is a measure of a person's cognitive ability different from rationality. IQ is measured with tests that contain cognitive tasks that are very general and do not require specialization/schooling to answer, thus IQ heavily overlaps with common sense. It is assumed no training has taking place for the IQ test, but modern IQ tests are also fairly sturdy i.e. resist the training effects and only mainly test unlearnable faculties such as processing speed, bandwidth and logic. | '''IQ''' or '''intelligence quotient''' is a measure of a person's cognitive ability different from rationality.

Performance on different IQ tests correlates somewhat (r = ~0.5) which everyone 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 the more intelligent generally have more efficient and functional brains on a physiological level. | Performance on different IQ tests correlates somewhat (r = ~0.5) which means everyone 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 to any given problem and a path to any given goal. | 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.
