But that leads us to another conclusion. If men have a higher rate of those in the 130+ range, then there is also a higher rate of those whose IQ=<70. So, it seems that in men the distribution of intelligence is much more extreme than in women. This can be explained by the fact that, historically, the criteria for choosing a quality man for procreation, marriage and family care were different than the criteria for choosing a woman, which had a generational effect on the genetic distribution of intelligence.

But that could be just one of many reasons. And that's just some of my superficial thinking and conclusions that I drew, without any research and deeper thinking and analysis of this issue. Maybe I'm wrong.
