Hmm... Sometimes even I say "maybe women just prefer [...]", but actually mean exactly that, what you said: There are social trends and in this case there is a social trend specific to women wrongly being taught that they are not as good as men in STEM fields. So much in fact (here in Germany) that it's kind of unsettling, when they tell you "haha I'm just not good in math haha" and you can't even, because it's so effing wrong.
I believe many (young) people will tell you that women are "just" like that, but actually mean "they are just taught to think so", because in their male position there is no need to choose are careful wording. I'm also pretty sure that, while the society at large is fault for this herd thinking about this, the parents play the biggest role in where the daughter places herself in the world.
Could be, but a lot of people take that "just" as meaning "there are essential gender differences rooted in the very fabric of the universe, so there's no point in talking about it". So if I were trying to point at the social factors that shape general preferences, I'd look for a phrasing that can't be taken for a call, as here, to ignore those factors.
