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

Performance on different IQ tests, school grades and work performance all correlate somewhat (r = ~0.5) which means IQ tests can predict ''general intelligence'', short ''g'', the ability to act intelligently in ''any'' cognitive task, even those tasks which haven't been tested. A task in which people's performance correlates with g to some extent is said to be ''g-loaded''. g is assessed by a battery of tests. It has been suggested at least three tests | Performance on different IQ tests, school grades and work performance all correlate somewhat (r = ~0.5) which means IQ tests can predict ''general intelligence'', short ''g'', the ability to act intelligently in ''any'' cognitive task, even those tasks which haven't been tested.
