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. | 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. | 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.

Even real-life cognitive tasks like school, work and social performance (but only declarative knowledge about social events, not so much gossipy socializing<ref>https://psychology.stackexchange.com/questions/9746/does-high-iq-correlate-with-good-social-skills</ref>) are just as much correlated with general intelligence as other IQ tests. It is an imperfect measure, but it allows to decide about extremes very reliably, e.g. a person with IQ less than 90 is very likely to fail in an academic math course. 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> | Even real-life cognitive tasks like school, work and social performance (but only declarative knowledge about social events, not so much gossipy socializing<ref>https://psychology.stackexchange.com/questions/9746/does-high-iq-correlate-with-good-social-skills</ref>) are just as much correlated with general intelligence as other IQ tests.
