Check out the actual statistics on what women and men choose an occupations when both people-related and non-people-related jobs are otherwise equal. Therese quite a bit of evidence that men and women tend to prefer occupations in one or the other category.

Honestly, looking at how different men and women are physically, it is slightly absurd to assume that they are identical psychologically (i.e. have the exact same preference regarding people-oriented vs. Technical occupations).
