Q

What is the difference between mean intelligence and variance in the context of gender?

A

In the context of gender, the mean intelligence between men and women is statistically indistinguishable, meaning that average IQ scores are similar. However, the variance in men's intelligence is slightly greater, resulting in more men at both the extreme high and low ends of the achievement spectrum. This variance, rather than mean intelligence, accounts for the overrepresentation of men in high-achieving roles.

This is one answer. The complete system — the psychology, the biology, and the method — is in the book.
