This can be tested by estimating how much IQ screens off race/gender as a success predictor
Got any good references on that? Googleing these kind of terms doesn’t lead to good links.
National average IQ is strongly correlated with national wealth and development indexes
I know, but the way it does so is bizarre (IQ seems to have a much stronger effect between countries than between individuals). Then I add the fact that IQ is very heritable, and also pretty malleable (flynn effect), and I’m still confused.
Now, I’m not going to throw out all I previously believed on heredity and IQ and so on, but the picture just got a lot more complicated. Or “nuanced”, if I wanted to use a positive term. Let’s go with nuanced.

I don’t know if anybody already did it, but I guess it can be done by comparing the average IQ of various professions or high-performing and low-performing groups with their racial/gender makeup.

This is probably just the noise (i.e. things like “blind luck”) being averaged out.

Heritability studies tend to be done on people living in the same country, of roughly the same age, which means that population-wide effects like the Flynn effect don’t register.

And another plausible explanation is added to the list...

Oh, I understand why this is the case. It just means that the outcome of many changes (if they are country-wide) are hard to estimate (and are typically underestimated from twin studies).

Why is this bizarre? It simply means that high IQ individuals don’t capture all the value they create.
Edit: another possibility is that smart people tend to move to places that were doing well. I believe there was a thread in the comments to SSC a while back where it was discovered that the average IQ of American States correlated with a rather naively constructed measure of “favorable geography”, e.g., points for being on the coast and for having navigable rivers.

Consider that if it had been the opposite—IQ was more a personal benefit than a country benefit—we’d be explaining it as “obviously smart people benefit themselves at the expense of others”. Being able to explain something or its opposite isn’t explaining, unless we dig deeper.

Yes, it’s called basing your beliefs on the evidence.
No, it’s choosing the first plausible rationalisation for the data. People have been suggesting lots of plausible explanations for the effect, and they all sound plausible (and may all the true, to some extent), but we really don’t know until we test.

So, why were you calling reality “bizarre” again?
