IQ basically has to do with academic achievement, which is correlated with income in today’s world. If you have a low IQ, it’s unlikely that you’ll be a good astrophysicist, but it’s just as unlikely if you have a big IQ and no self-discipline.

A lot has to do with how the test is formulated as well. You can’t measure it directly - so what indirect means are you using? Volcabulary, general knowledge, etc. And a poorly designed one will bring in a lot of cultural baggage, and then suddenly minorities and immigrants test out poorly due to not being knowledgeable about the predominant culture in the ways you expect.
