For example, in 1940, nearly all American Jews married other Jews. Now, the fi gure is only 50 percent. In some cases, it takes one or two generations for new opportunities to be reflected in people's marital preferences and behavior. Here is a more striking example. Buss proposes that women also have an innate psychological propensity to seek a husband who is few years older.
Older men command more resources than younger men.
They don't stampede to marry men who are lots older, bec ause men who are lots older have a higher risk of dying soon. Again, the theory is impeccable. There is also decent evidence for it. In nearly all societies that have been studied, husbands are several years older than their wives. I have a piece of counter-evidence, though.
