Even real-life cognitive tasks like school, work performance and social skills (but only declarative knowledge about social events, not the kind of gossipy socializing<ref>https://psychology.stackexchange.com/questions/9746/does-high-iq-correlate-with-good-social-skills</ref>) 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 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 performance and social skills (but only declarative knowledge about social events, not the kind of gossipy socializing<ref>https://psychology.stackexchange.com/questions/9746/does-high-iq-correlate-with-good-social-skills</ref>) are just as much correlated with IQs, so IQ can tell us a lot about people's overall performance.
