Performance on different IQ tests, school grades, work performance and attained SES<ref>https://www.sciencedirect.com/science/article/pii/S0160289697900039</ref> all correlate somewhat (r = 0.5 to 0.6) 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 and hence with all other IQ tests is said to be ''g-loaded''. It has been suggested a battery of at least three tests are necessary to accurately determine g (short-term memory, reasoning and verbal skills).<ref>https://www.telegraph.co.uk/news/science/science-news/9755929/IQ-tests-do-not-reflect-intelligence.html</ref> | Performance on different IQ tests, school grades, work performance and attained SES<ref>https://www.sciencedirect.com/science/article/pii/S0160289697900039</ref> all correlate somewhat (r = 0.5 to 0.6) 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.

General intelligence becomes more predictive of task performance the more complex the task is.<ref>https://journals.sagepub.com/doi/10.1177/0013164498058002011</ref><ref>https://www.researchgate.net/profile/Chockalingam_vish_Viswesvaran/publication/319381272_A_Failed_Challenge_to_Validity_Generalization_Addressing_a_Fundamental_Misunderstanding_of_the_Nature_of_VG/links/5a3006d4458515a13d852c84/A-Failed-Challenge-to-Validity-Generalization-Addressing-a-Fundamental-Misunderstanding-of-the-Nature-of-VG.pdf</ref> | |||
This means IQ tests can be used for screening. Even though IQ is an imperfect measure, it allows to very reliably decide for example that 115 is a minimum for achieving a graduate degree with satisfying grades.<ref>http://emilkirkegaard.dk/en/wp-content/uploads/Bias-in-Mental-Testing-Arthur-R.-Jensen.pdf</ref> | This means IQ tests can be used for screening.

Even social skills are g-loaded, but only things like knowledge about social events, not so much the gossipy socializing aspect.<ref>https://psychology.stackexchange.com/questions/9746/does-high-iq-correlate-with-good-social-skills</ref> | Even social skills are g-loaded, but only things like knowledge about social events, not so much the gossipy socializing aspect.<ref>https://psychology.stackexchange.com/questions/9746/does-high-iq-correlate-with-good-social-skills</ref> | ||
