More complex jobs are more g-loaded, so g is even more predictive.<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> | More complex jobs are more g-loaded, so g is even more predictive.<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 are relevant for can be used for screening. Even though IQ is an imperfect measure, it allows to very reliably decide for example that a person with IQ less than 90 is very likely to fail in an academic math course and 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 are relevant for can be used for screening.

Even social skills are g-loaded (but only things like 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>). | |||
Various 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> have been found to be g-loaded. This has lead to the conclusion that the more intelligent generally have more efficient and functional brains on a physiological level. Abilities that are relevant for all cognitive tasks are for example to quickly learn, retrieve and process a maximal amount of information and to quickly consider different hypotheses without losing track of things. These abilities enable one to better find a solution to any given problem and a path to any given goal. | Various 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> have been found to be g-loaded.
