Does anyone know of a good graph that shows this? I've seen several (none citing sources) that draw the crossover in quite different places. So I'm not sure what the gender ratio is at, say, IQ 130.
La Griffe Du Lion has good work on this, but it's limited to math ability, where the male mean is higher than the female mean as well as the male variance being higher than the female variance.
The formulas from the first link work for whatever mean and variance you want to use, and so can be updated with more applicable IQ figures, and you can see how an additional 10 point 'reporting gap' affects things.
Unfortunately, intelligence in areas other than math seem to be an "I know it when I see it" kind of thing. It's much harder to design a good test for some of the "softer" disciplines, like "interpersonal intelligence" or even language skills, and it's much easier to pick a fight with results you don't like.
It could be that because intelligence tests are biased toward easy measurement, they focus too much on math, so they under-predict women's actual performance at most jobs not directly related to abstract math skills.
