EDIT: Typo. It's MALES who have less interconnected brains. I'm not saying it means that men are smarter at everything. That is not the case. It's more like we have brain damage that gives us rain-man like abilities compared to women because our brains cannot do what women's brains can do so we focus on what we can focus on. It's a disability that frees us up to do what we do best, not unlike blind people getting more information from sound even when their hearing is no better than anyone else's.
This is intentional hyperbole to make a point, but the cumulative effect on large populations is noticeable and measurable.

I don't give a shit if you call me "sexist" or not. Name-calling is not rational argument.
