Men's brains are 8 to 13% bigger depending on age. It doesn't seem to lead to higher IQ (itself a terrible measure), though men (boys) are a lot more likely to be diagnosed with a bunch of issues like autism...

"Males’ brains are larger than females’ from birth, stabilizing around 11 % in adults. This size difference accounts for other reproducible findings: higher white/gray matter ratio, intra- versus interhemispheric connectivity, and regional cortical and subcortical volumes in males. But when structural and lateralization differences are present independent of size, sex/gender explains only about 1% of total variance." -- the abstract

  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...

Note that brain size can be as much affected by gender than by country of birth.

  I didn't know that, but I am happy to accept it as long as someone has done the research. Given how little brain size actually matters (it's not like blue whales are the dominant species and they win the size race), I don't get why people have such a problem with these stats...

    Clearly optimizing education can offset those difference by order of magnitudes especially if rationality and cognitive biases/logical fallacies where taught
