Sorry, I feel like I'm missing your point. Per your comment male brains are bigger and different in other ways. You can argue about whether a male brain is bigger because it is male, or because it has higher white/grey ratio because its male. Either way, male -> bigger. Again, I'm not saying bigger is better or smarter or whatever. I'm just pointing out that submitted article seems to be unaware of other (well reproduced) work that disagrees with its conclusions...
