"Where there are plenty of studies that show sex hormones affect the brain, and that there are some group-level differences between male and female brains—for example, on average, women have more gray matter then men—what’s not proven, according to Joel, “is that these effects add up to create two types of brains: male and female.”" I suppose we can keep this up and dance around definitions forever. What's there to prove? You either can make a statistically significant guess that a brain belongs to a man or a woman based on a scan or you can't. I'm not qualified to have an opinion on the matter but honestly, I think people pushing this are doing more harm than good regardless of their intentions.
