The positive manifold between different cognitive tests (which is what IQ actually is) is one of the most widely replicated findings in psychometrics. It predicts everything from your grades in school, to your odds of getting into a graduate program, to your lifetime earnings, to your odds of getting divorced.
It’s more strongly correlated with some things vs others (for example it’s more predictive of school grades than it is of income), but it’s one of the single most important factors influencing the trajectory of your life.
Obviously there are many other important aspects of life, but IQ influences a lot of them!
Setting aside whether any of the tests’ narrow set of measures says anything constructive or useful about human beings at all.
