@sickburnbro fantastic post, except that the justification is slightly flawed

as the economy becomes more complex, contributions to GDP are more and more dominated by the right tail, which is mainly male due to men because men have a higher variance

this is running off of the studies that produced the first attached image. The problem is that these studies all sampled children aged 8-13, where most women had several years of puberty, while only some males had begun puberty. This explains why the results have a higher variance for men, and why women appear to have a higher IQ than is generally observed in reality.

The real distribution is closer to pic 2, with women following a similar curve but falling off the right tail more readily compared to men.
