Oh, baby! The arrival of a newborn has a dramatic impact on the mother’s hormones—no surprise—as a rush of biochemical reactions occurs to improve attachment and attentiveness. Oxytocin, a hormone that increases the amount of love and protectiveness new mothers feel towards their offspring, has been called the “love drug” because it helps new mothers bond with their babies.
"Maternal oxytocin levels—the system responsible for maternal-infant bonding across all mammalian species—dramatically increase during pregnancy and the postpartum [period] and the more mother is involved in childcare, the greater the increase in oxytocin," said brain researcher Ruth Feldman.
If you’ve any doubt that sexism is alive and well in the United States, look no further than recently fired Google employee James Damore who disseminated a 10-page long manifesto criticizing Google’s diversity policies in favor of men. Damore hung his sexist hat on evolutionary psychology, a controversial field that suggests psychological traits are selected in the same way as our biological traits via evolution, which then confers entitlements like better pay and promotions to those he deems superior, namely men.
His conclusion? That men and women “biologically differ in many ways,” and thus, men have a biologically-based “higher drive for status” which suggests that men are somehow more inherently entitled to make more money than women. “We need to stop assuming that gender gaps imply sexism,” Damore wrote, while apparently ignoring the evidence that sexism is, in fact, strongly associated with women receiving lower pay than men on average in almost every field imaginable.
