Then that would more be a aspect of social expectations, no? Perhaps I've read to much malice into the word "systemic bias", as if people were actively working against someone doing the particular thing there is bias against, where it is more a result of social expectations on what is "proper" for each gender. Again, only speaking from my Danish perspective, but I've never met anyone thinking STEM of all things would not be fit for females, but you probably would get that reaction if you were to say, as a female, that you wanted to become a plumber or similar hands-on jobs. --- Slightly going off-topic: Personally, I think the disparity we see, currently, in STEM et al, is for historical reasons, as younger boys used e.g. computers as an escape from socialising, and thereby grew interested in that particular field. I also think this is why it is sometimes met with a bit of a scuff from some in the tech community, because what was previously viewed as a something nerdy, uncool and with a lot of negative stereotypes attached to it, is all of the sudden the new cool thing, and people that suffered through bullying for being "nerdy" and generally not having the time of their life in younger school life, are now being touted as if they were privileged all along, which very much undermines the struggles they had during their upbringing. This is mostly guesswork from intuition, since I personally did not have any trouble fitting in, yet even I got the "nerd" remark if I would tell people my interests, so I don't feel I was particularly encouraged or anything into this—in fact, most are probably here despite that.
