have maximized the differences between men and women there's only two reasons that men and women different one is cultural and the other is biological and if you minimize the cultural differences you maximize the biological differences so for example on average men are more interested in things and women are more interested in people and that's actually the biggest difference we know of psychologically between men and women in order to become an engineer you have to be extraordinarily interested in things rather than people most of those people are mad and if you want to become a nurse well then you have to be much more interested in people than you aren't things and most of those people are women and so you get differences in occupational choice there are mostly due to biological differences and you cannot minimize that by social engineering
