All of this is due to socialization. There is no such thing as a gendered brain at birth, other than tiny differences which can be accounted for by size differences. Please stop spreading this BS. It's antiquated, misogynistic and contributes to things like homophobia and the very real struggles that so many men face trying to fit into the "man box."
“For example, once any differences in brain size were accounted for, “well-known” sex differences in key structures disappeared. Which is when the penny dropped: perhaps it was time to abandon the age-old search for the differences between brains from men and brains from women. Are there any significant differences based on sex alone? The answer, she says, is no. To suggest otherwise is “neurofoolishness”.
“The idea of the male brain and the female brain suggests that each is a characteristically homogenous thing and that whoever has got a male brain, say, will have the same kind of aptitudes, preferences and personalities as everyone else with that ‘type’ of brain. We now know that is not the case. We are at the point where we need to say, ‘Forget the male and female brain; it’s a distraction, it’s inaccurate.’ It’s possibly harmful, too, because it’s used as a hook to say, well, there’s no point girls doing science because they haven’t got a science brain, or boys shouldn’t be emotional or should want to lead.”
“They say, ‘I have a son and a daughter, and they are different.’ And I say, ‘I have two daughters, and they are very different.’ When you talk about male and female identity, people are very wedded to the idea that men and women are different. People like me are not sex-difference deniers,” continues Rippon. “Of course there are sex differences. Anatomically, men and women are different. The brain is a biological organ. Sex is a biological factor. But it is not the sole factor; it intersects with so many variables.”
One major breakthrough in recent years has been the realisation that, even in adulthood, our brains are continually being changed, not just by the education we receive, but also by the jobs we do, the hobbies we have, the sports we play. The brain of a working London taxi driver will be different from that of a trainee and from that of a retired taxi driver; we can track differences among people who play videogames or are learning origami or to play the violin. Supposing these brain-changing experiences are different for different people, or groups of people? If, for example, being male means that you have much greater experience of constructing things or manipulating complex 3D representations (such as playing with Lego), it is very likely that this will be shown in your brain. Brains reflect the lives they have lived, not just the sex of their owners.”
