But why does the same trend persists across cultures? The same is true for any developed country in the world. Do you think your tech culture is also interwined with that of Australia, Poland, Sweden and Italy?

Yes, to a great deal, it is.

Yes, to an extent it is. But it's very difficult to quantify how big the effect on culture is on womens choices to not even pursue education in tech. It seems, for an example, extremely unlikely that a young woman basically anywhere in these countries, would say to herself, "hmm, I've heard that there's mansplaining at Google, so I think I'll go into law or investment banking or medicine instead".

The misogynism we're imploring ourselves to eradicate is so subtle, it's unconscious biases and micro-aggressions (that is, agressions you don't know you're committing). When we can barely detect them ourselves, how would they be able to embed themselves into the subconscience of millions of young girls across dozens of quite different cultures?

And that's without considering the quite numerous fields with a high degree of misogyny embedded as a broad popular culture trope. "Suits" does not envision a law-field that is particularly friendly to women, "Billions" : finance, "Scrubs" : medicine. Women have no issue with pursuing careers in those fields. That's not excusing bad behaviour, just observing that this behaviour, and broad knowledge of it, does not appear to deter women, and to serve as a counterpoint to the assertion that the far more subtle and much less broadly portrayed alleged misogynism of tech should be detering women.

And probably more than with some subcultures in the same country.
