In my household the superior intelligence of women (over men) is a fact of life. The observation is validated by experience, which is to say that the scientific method applies in my home.
The article at the link seems to suggest that my familial experience is false. The article claims that men as a group have higher measurable intelligence than women.
I have my doubts. As an evolutionary strategy, it is probably better for women to be smarter than men, and not tell us.
