For example high IQ perdicts better outcomes occupation, job performance , academic performance

And does so better than any other psychological factor
IQ predicts upward economic mobility, for example it explains all of the black-white gap in upward economic mobility, i.e. a poor black kid is as likely to improve his socioeconomic class as a poor white kid as long as they both have the same IQ (btw exactly the opposite of what you would expect to observe if the differences in black and white outcomes are due to black people being treated unfairly which makes it more difficult for them to succeed than a white person of the same ability)

Even within high IQ people, being very high IQ predicts better outcomes
For example in the SMPY study of mathematically precocious youth, they looked at a cohort of children in the top 1% of mathematics ability, and even within that 1 % the children in the top quarter of that 1% had substantially better life outcomes than the children at the bottom of that top 1%
