I tried thinking of a good argument against it because it seems unintuitive. From everything I see, women are ENCOURAGED to go into STEM fields. They are significantly more likely to be hired and promoted when compared to their male counterparts, and get all sorts of support and scholarships.

Are you suggesting there aren't any psychological differences between men and women? Because testosterone has been shown to cause people to be more competitive, assertive, and violent. That's a pretty good indicator of a difference in psychology. We are of course talking about trends here. There are of course individual exceptions to the norm.
