* Indeed, it’s possible that sex differences in college graduation rates will prove to be a much bigger problem than sex differences in math and science participation. Since the late twentieth century, women have been more likely than men to graduate from college in the United States. On the one hand, you could view such statistics as righting a historical wrong, given that women were once prevented from attending some of the best colleges. On the other hand, women rarely marry less-educated men, so differential graduation rates may cause relationship problems for the foreseeable future. Because marriage is good for men, and unmarried men are bad for society, this sex difference in education may lead to all sorts of individual and societal disruptions.
