Evolutionary Psychology and Human Nature:

A fascinating article examines the question of human nature, focused particularly on relations between men and women. For example, did you know that monogamy is bad for women, whereas polygamy is bad for men?

Relative to monogamy, polygyny creates greater fitness variance (the distance between the "winners" and the "losers" in the reproductive game) among males than among females because it allows a few males to monopolize all the females in the group. The greater fitness variance among males creates greater pressure for men to compete with each other for mates. Only big and tall males can win mating opportunities. Among pair-bonding species like humans, in which males and females stay together to raise their children, females also prefer to mate with big and tall males because they can provide better physical protection against predators and other males.

In societies where rich men are much richer than poor men, women (and their children) are better off sharing the few wealthy men; one-half, one-quarter, or even one-tenth of a wealthy man is still better than an entire poor man. As George Bernard Shaw puts it, "The maternal instinct leads a woman to prefer a tenth share in a first-rate man to the exclusive possession of a third-rate one." Despite the fact that humans are naturally polygynous, most industrial societies are monogamous because men tend to be more or less equal in their resources compared with their ancestors in medieval times. (Inequality tends to increase as society advances in complexity from hunter-gatherer to advanced agrarian societies. Industrialization tends to decrease the level of inequality.)

When there is resource inequality among men—the case in every human society—most women benefit from polygyny: women can share a wealthy man. Under monogamy, they are stuck with marrying a poorer man.

The only exceptions are extremely desirable women. Under monogamy, they can monopolize the wealthiest men; under polygyny, they must share the men with other, less desirable women. However, the situation is exactly opposite for men. Monogamy guarantees that every man can find a wife. True, less desirable men can marry only less desirable women, but that's much better than not marrying anyone at all.

Men in monogamous societies imagine they would be better off under polygyny. What they don't realize is that, for most men who are not extremely desirable, polygyny means no wife at all, or, if they are lucky, a wife who is much less desirable than one they could get under monogamy.
Actually, it sounds like polygamy is better for men too, in the long run -- it creates men who are stronger and fitter in the future. It's just bad for the current crop of men, who want to get women and can't.

Oh, and for those who'd prefer to avoid suicide bombers. The role of Islamic polygamy in suicide bombing is considered in the article as well. More shockingly, from a personal perspective, is this claim that feminists were right: chivalry and courtesy are forms of discrimination against women. Men who don't discriminate against women instead use sexual harrassment:
Sexual harassment cases of the hostile-environment variety result from sex differences in what men and women perceive as "overly sexual" or "hostile" behavior. Many women legitimately complain that they have been subjected to abusive, intimidating, and degrading treatment by their male coworkers. Browne points out that long before women entered the labor force, men subjected each other to such abusive, intimidating, and degrading treatment.

Abuse, intimidation, and degradation are all part of men's repertoire of tactics employed in competitive situations. In other words, men are not treating women differently from men—the definition of discrimination, under which sexual harassment legally falls—but the opposite: Men harass women precisely because they are not discriminating between men and women.
I suppose I'll have to accept the role of a proud discriminator, then. Grim's Hall continues to insist on chivalric behavior toward ladies, in spite of these new revelations.
