If you google "Zlatan Krizan gender differences" you can see that Leah has simply paraphrased a couple of articles already written on this topic (first page of search results) and added a personal anecdote. Deep research.

Anyway, 20-25% difference between the sexes is still considerable and can account for a lot of the observable difference in preferences and behavior. As a man, I do find the color pink utterly repulsive, honestly.

 I also have much less interest in people and getting along with people; as compared to my wife who is truly bothered when at odds with someone and thinks friends are important (I'm much more interested in things and ideas). 

I also enjoy taking risks while my wife much prefers certainty and less excitement. I never recall my parents telling me to break the speed limit because I'm male and that's expected (pretty sure they would have told me the opposite).
