Hmmm, this article doesn't exactly mention the nature of the gender discrimination against men in the technical and scientific fields. I can only guess at what they're referring to:
Should colleges and universities adopt affirmative action for men? By their own standards, the answer appears to be yes. Economist Mark Perry calls attention to a recent report from the Bureau of Labor Statistics. It shows that for every hundred men who have a bachelor's degree by age 24, a whopping 148 women of the same age do.My guess is that in encouraging girls to enter careers in the technical and scientific fields that may be causing hostile environments for the young men. Either that or the men aren't encouraged as much as the ladies.
In every other academic realm, the existence of a statistical disparity — such as the fact that fewer men than women pursue advanced degrees in certain science and technology fields — is taken as definitive proof of gender discrimination.
For instance, in 2010 the American Association of University Women lamented the "striking disparity between the numbers of men and women in science, technology, engineering, and mathematics," and concluded that "we must take a hard look at the stereotypes and biases that still pervade our culture. Encouraging more girls and women to enter these vital fields will require careful attention to the environment in our classrooms and workplaces and throughout our culture."
