> And all the studies done to understand those numbers show the difference in outcome is driven by tze social environment and esucation systems, and not the sexe.
No this is wrong, the studies done has shown that you can make girls do better and boys do worse by priming them. No study done has shown that you can eliminate this gap, just move it towards boys or girls being advantaged.
> You, of course, will ignore that I am sure
No, I read those studies. The stereotype threat paper just show that you can boost girls performance at the cost of boys performance and thus get equal performance at math, not that you can get relative equal performance at math and language. No such paper has shown that you can eliminate the language-math gap between girls and boys, and all data shows that the language-math divide for boys and girls stays the same.
So, all the progressive help to get girls better at math just made girls equal to boys at math, but now girls has an enormous advantage at language because they boosted girls score overall, they didn't make things equal.
