Perhaps women have always been smarter. Who knows? Women being encouraged in their intellectual pursuits is only a 100 year old phenomenon.

I think the more likely explanation is that the last few generations of intelligent have had more girls than boys. Hence the higher current number of female geniuses. It is proably random and incidental.

Plus the fact that in America we tend to love our daughters and don’t abort them as in other (Eastern) cultures, which also skews the data.

Geez, I really struggled typing that paragraph.

I think girls are more dutiful to study, which enables a larger cohort to get to, and graduate, from college as well. As the most successful and smart people tend to bear children later in life, this (in my opinion) also makes them more likely to have girl children. I have noticed this among horses as well-the older the mare, the more likely she is to have fillies. Nature’s way of replacing themselves, I guess.

Depends on what one means by genius. Terman’s geniuses included no Einsteins.
