A stereotype always has an aspect of truth to it, or it wouldn’t be a stereotype. I am talking about the biological basis behind behaviors that we all know about.It's not the shrunken brain, you know, it's the childcare. But you will have a shrunken brain.
Were there any research findings you were reluctant to include in your book because they could be used to bolster sexist thinking?
Any of this could be taken badly. I worried, for instance, that stuff about pregnancy and the mommy brain could be taken to mean that mothers shouldn’t go to work. The brain shrinks 8 percent during pregnancy and does not return to its former size until six months postpartum....
If women have superior verbal skills, why have they been subservient to men in almost all societies?
Because of pregnancy. Before birth control, in the 1700s and 1800s, middle-class women were pregnant between 17 and 22 times in their lifetimes. All these eons upon eons, while Socrates and all these guys were sitting around thinking up solutions to problems, women were feeding hungry mouths and wiping smelly behinds.
ADDED: Linguist Mark Liberman has been very critical of Ms. Brizendine.
