> Everyone knows that testosterone makes young men orders of magnitude more violent
You're using hyperbole but yes it's commonly understood that there's a link between testosterone and aggression, however you extend that claim to something completely different
> why is it inconceivable that they could also be 4 times more interested in more mechanic play? It’s been observed even in almost newborn chimpanzees for Gods sake.
I counter that this second claim is related to the first, is it that testosterone makes young males more likely to play with mechanical objects? There are a few articles that reference this study from 2008 [1]. It refers to rhesus monkeys not chimpanzees and their hypothesis at the end is much more nuanced

Furthermore there is at least 1 meta-analysis from 2017 [2] that highlights

Note they do not make the claim that testosterone is the cause of these differences. Scientists try to be careful about the language they use, we should be just as careful.

You haven't been exposed to a very broad range of parents. I've seen parents who very tightly control which toys, clothes, and grooming choices their kids make because they don't align with the parent's gender expectations. It's frustratingly common in the US.
Is it plausible to assume that STEM fields and female participation is a case where stereotypes have very little effect? I think I'd need some pretty strong evidence for the idea stereotypes had little effect on any kind of career choice. Even less so for fields where any mention of stereotypes and gender imbalance garners a furious insistence that the stereotype is [i] irrelevant to anyone's advice or decision making [ii] also such an accurate representation of biologically-driven preferences it would be unfair for the gender ratio to change
Specifically to quote your post: "toy preferences reflect hormonally influenced behavioral and..."
Also, I would think that the person that claims discrimination would have the burden of proof.
>Gender differences in toy choice exist and appear to be the product of both innate and social forces.
Gender seems to make some sort of difference but social factors also seem to make a difference. There is no claim to which is stronger, just that there is a difference. Taking this a step further I hypothesize that social forces could be enough to meaningfully change the gender difference.
And yeah, I think it's a potential contributing factor (one of many). Kids in many parts of the country are socialized that certain things are only for certain genders. It sucks. Let kids like whatever they want.
Well yes, if stereotypes or discrimination play any role it at all in career selection, it rules out the possibility that the highly variable ratio of male to female computer scientists is determined solely by biology. This strikes me as a much stronger claim requiring much stronger proof than a statement to the effect that [the well-established existence of] stereotypes is amongst the driving factors in career selection; particularly given that the ratio of male to female computer scientists varies hugely by place and time in ways which would be very difficult to attribute solely to biology.
Since it's palpably absurd to attribute this to differences between Russian and other European female biology, I think you've just refuted the argument that biology is likely to be the sole factor determining career choices. Given that we have just proven that cultural attitudes do shape career choices to some extent, perhaps they are even partly influenced by some people's insistence that the only actually problematic attitude towards female participation in their field is considering women equally likely to be suited to the job?
I don't really understand your logic. The biology is the same in both places, but we can all agree that Sweden is 100 times more progressive. Even if you claim there are still stereotyping here, their effect would be much much smaller. How can that be reconciled with the much larger disparities we see in Sweden?
