For centuries, scientists have argued that there are inherent differences between male and female brains, which accounts for their different roles in society. That’s not true, argues Gina Rippon in Gender and Our Brains. She makes the case that much of that research suffers from bias; researchers confirmed what they already “knew” to be true. Instead, she believes, our brains are gendered because our experiences are. We are treated differently based on our perceived gender, and our brains develop in response.
