If that is the study I remember, I don't think it shows women are deemed less capable. It might as well be possible that women are deemed less likely to follow through with their studies (for example because they might drop out to have kids), making them a worse investment. That's of course still a problem, but a different one than you make it to be. I think if there is an actual issue like that (if women are a less promising investment), rather than crying "sexism", society should compensate for it somehow. Why should it be the burden of employers to insure against women's life choices?
