Is sexism caused by a differently shaped brain?

Doing some research and came across this article, “Are Some Brain Predisposed for Sexism?” It’s interesting reading and I may do some follow-up research to see how valid the claim is. In the meantime, the latter part of the article (the influence of societal factors) makes sense to me. The developing brain is like putty”we know children who are talked to, read to, played with develop better than those who don’t have that type of interaction. So if a child is/isn’t exposed to certain types of thought and behaviours, it seems logical their brain would develop differently.
