Agreed. Thank you for your post! That's basically exactly what the book I recommended says, except she goes into 200+ pages of detail about it (with much supporting evidence.)
It is -- and that book should be required reading for anyone making any comment on this subject. It's shocking how often I see posts, especially on Hacker News, that take for granted "gender differences" that have been proven not to exist! And often by self-proclaimed scientists and skeptics, no less.
