Google Employee Memo: Read YouTube CEO Susan Wojcicki's Response

We have reviewed overwhelming evidence that genetic and hormonal differences between males and females are major causes of sex differences in behavior. These include differences in social behaviors in infants, play behaviors, interests, activities, educational and vocational goals, choices of occupations, patterns of cognitive abilities, and the frequency of extreme giftedness in spatial, mechanical, and mathematical ability. The dominance of female doctoral students in the life and human sciences and of male doctoral students in the inorganic sciences and engineering is consistent with and predictable by sex differences in interests and ability patterns. The greater social interest and ability of females than males is evident in infancy. The differing play activities and interests of boys and girls share similarities with sex differences in the play behaviors of nonhuman primates. Interests, activities, values, and vocational goals that differentiate girls from boys and women from men are strongly affected by the level of fetal androgen exposure or tissue sensitivity to androgen.

There's interesting stuff in the field, but absolutely nothing that would warrant telling a woman "the science is in". Especially given the track record of people itching to chalk injustice up to biology.
