You and I might have smidgens of autism and not realize it, especially if you happen to be a man. Scientists have sometimes described autism as an extreme version of the male brain. And in truth, of all the world’s autistics, only one fifth are female.3 This may be because women have more axons and dendrites, which are the pathways in the brain that enable it to work as a unit. Men’s brains have more neurons. In effect, this makes male brains less networked than women’s, but outfitted with more processing power, largely focused, it seems, on spatial and temporal capabilities. This doesn’t make one sex smarter or more talented than the other, simply different. It also helps explain, at least according to some scientists, why men are sometimes less socially tuned in than females, and why women are superior, generally, at reading social cues.
