Silicon Valley's Weapon of Choice against Women: Shoddy Science.

Human brains show great variability in the sizes of various areas, but this variability has only a small statistical correlation with the humans' sex. Thus, the brain variability among male humans, or among female humans, swamps the difference between the sexes.

A human's every thought is embodied as a change in the brain. In particular, every habit or pattern of thought and action is a change in the brain. The observed statistical difference between male brains and female brains, being so small, could represent reactions to differences in the way males and females are typically treated in any given society.
