Schools have been changed since the 80s to specifically improve the performance of girls, particularly in maths and science. Is it unsurprising that this has worked, at the expense of boys?
Girls have outperformed boys up through high school since before they were keeping track of statistics like that. It's a cliché, even. This is not a new or surprising effect.
And I repeat my point: there are a lot of men here on HN who seem unprepared to accept a world where women's performance in entry level career work is actually higher than men's, even though that would seem like an obviously extrapolation from well-understood data.
I repeat my point from other comments again here: If women are so cheap and so talented, they don't need preferential treatment. They will be rewarded naturally according to their abilities without all that. You seem unprepared to accept a world where women aren't given preferential treatment over men under the pretense of victimhood. You claim women are better at various things but refuse to acknowledge that men are discriminated against purely to promote women (because DEI, not because they are better in any way).
