In 2013 a team from Taiwan, Cyprus, and the United Kingdom (in which, incidentally, one member was neuroscientist Simon Baron-Cohen) highlighted another. They got together a large number of independent studies into sex differences in brain volume and density to see what they could tell us in summary. In their paper published the following year, the team proclaimed that men’s brains were typically bigger by volume than women’s brains. The gap ranges from 8 to 13 percent.
