This seems highly unlikely; in all-male schools the students choose a broad variety of topics, and I don’t see why women would be any different. It’s also dangerous to draw general conclusions from situations involving children/teenagers, who by-and-large do what they’re told, and are more susceptible to peer pressure. You’d be able to check the strength of such effects by tracing the subjects 10 years later and checking whether they’re in science-related careers. Can you reference specific studies? I can’t find any hard numbers.
Incidentally, do you realise you’re actually suggesting that men and women are inherently different in their susceptibility to social pressure … and therefore may be inherently different in other important ways?
