Members of both sexes can be found at every point on the things vs. people continuum; however, more men than women exhibit a stronger interest in thi… - Steve Stewart-Williams

As a result of high levels of male parental investment, humans evolved into a somewhat “androgynous” species - a species in which human females exhibit traits generally found only in males (e.g., competition for mates) and human males exhibit traits generally found only in females (e.g., the provision of parental care; choosiness about mates).

[W]e should strive to eliminate bias and barriers of every kind... What we would argue, though, is that even if this were achieved, STEM gender gaps would be unlikely to disappear given persistent sex differences in interests and other STEM-relevant traits – differences plausibly due in part to biological causes. The question, then, is: Would this necessarily be a problem? In our view, as long as unjust impediments are removed, and everyone is invited, it would not be. On the contrary, it would be unfortunate if, for all the talk of celebrating differences and diversity, we ultimately came to insist that justice requires sameness.

Sex differences in occupational preferences and priorities suggest one possible reason that more men than women go into maths-intensive STEM fields. The reason, put simply, is that more men than women want to go into these fields.
