Isn't it pretty widely accepted that your IQ, at least as measured by IQ tests, aren't a perfect measure of your "intrinsic" intelligence; that environmental factors contribute to IQ test results?
If environmental factors do indeed contribute to IQ scores, doesn't it seem pretty plausible that lower GDP per capita, which results in changes to environmental factors such as education, might result in lower IQ scores, rather than the other way around?
It'd be interesting to read studies which investigate whether there's a causal link between IQ and GDP per capita, and if there is one, which one causes the other.
