And my own personal observation at secondary school when choosing GCSE’s..
out of 250 kids in my year only one girl chose wood/metal work. None of the boys chose cooking/sewing. Complete division along gender lines.
was it because no girls wanted to do metalwork? Or boys wanted to do cooking? No, it was social fear of being seen as odd, girly, butch, lesbian etc. of being the only one in a class of the opposite sex.
yes, I was that girl who did wood/metal work. I enjoyed it, I was good at it. But I ditched it asap, because the experience of being in a male class with a male teacher being treated as lesser.
same with physics/maths a’level. Only two girls took physics.
being a girl in a traditionally male environment is hard.
look at computer science/programming. Male subject, yes? But the original coders were female, as it was seen as akin to secretarial working- for typists.
once those females developed computer science to a level where men saw it’s worth, suddenly it became men who had the “natural” aptitude, and women were elbowed out.
