In no particular order:
- There's an overwhelming preference (across all academic and professional disciplines) for women to prefer working with people and for men to prefer working with things [1]
- Gender theory is a sociological and political theory that's often touted as being scientific. To be sure, it's contributed to science (e.g.: the idea that gender roles are socially-influenced), but the idea that men and women are equivalent outside of socially-constructed differences is (a) unsubstantiated (b) unfalsifiable (we can never fully remove social influence) (c) in contradiction with what cognitive neuroscience tells us about anatomy and physiology shape cognition.
Where gender theory has a role to play is in telling us how to structure our societies despite eventual differences between the sexes, but I really don't care for it's opinion on empirical questions.
