I’d like to consider a related question: why did our society “choose” monogamy as a social norm? One major clue is the high correlation between monogamy and economic development—virtually all modern industrialized societies have adopted monogamy as a social norm, whereas most societies throughout history have practiced polygyny. But what direction does the causal relationship run? (*)
Does it make sense to start tearing down this norm before we get that question sorted out? Several commenters have said that they’re not for or against polyamory, but they are for being aware of and considering the possibility of polyamory. But one way to enforce a social norm is to teach people to think in such a way that they do not even consider the possibility of violating it.
This is a good and important question. As the paper you linked to indicates, monogamous societies tend to have fewer children than polygynous ones; this, in turn, leads to a host of economic benefits.
But we should distinguish between polygyny and polyamory, which are not at all similar practices. The Trobriand people have a relationship-style that has much more in common with polyamory than polygyny, and this seems to be a direct result of their belief that sex does not cause pregnancy (which they possess because their diet greatly reduces the odds of conception).
While the Trobriand people are not economically well-developed, I think that their relationship-style is a result of that of lack of development and not the other way around. Consider: economic development would lead to a more varied diet, which would then restore conception rates to more normal levels and demonstrate a connection between sex and childbirth; prior to the advent of widely-available contraception, economically developed cultures and the varied diets that accompany them were incompatible with relationship styles similar to the Trobriand people’s.
If this explanation is true (and I acknowledge that the evidence is certainly not conclusive), modern contraceptive techniques might make non-monogamous relationship styles viable in a way that they might not be otherwise. Contraception certainly has the potential to limit population growth, which seems to be polygyny’s greatest economic downside. And we know from the Trobriand example that polyamory-type relationship styles are quite compatible with contraception.
Once a society attains a certain level of efficiency or productivity, changing social structures can free up significant amounts of otherwise untapped potential. Every modern industrial society had a rather rigid concept of “women’s work” until relatively recently. The technological advances (and immigration) that broke this tradition resulted in a tremendous increase in human capital and significant economic growth (among many other mostly-but-not-entirely good things).
Modern polygynous societies are vastly different from modern monogamous societies in ways that do not revolve around mono vs poly. Furthermore, I don’t think many societies have been tolerant of polyamory, as opposed to polygamy. Given that other values (having kids, working, buying needless crap) remain relatively constant, polyamory would likely help revive the strong social support networks of yesteryear and exhibit positive returns to scale versus the current system. This is not to say it would definitely result in an improvement, but demonstrating, “Polygynous societies aren’t that productive, therefore monogamous norms are vital to continued economic success” requires vastly stronger evidence than you cite.
It wouldn’t surprise me a bit if the predecessors to our society “chose” monogamy because it seemed like a good idea at the time, without any very coherent reasoning about the longterm effects.
The effects of breaking down monogamy are an entirely different question.
I think it may have something to do with limiting violence.
I’m trying to remember the reference (it might be Hanson or possibly the book the Red Queen Hypothesis—if I remember I’ll post it) but a vast majority of violence is over access to women, at least in primitive societies. Obviously mongamy means that the largest number of males get access to a female, thereby reducing losses in violent competition to females. I think this would certainly explain why rich societies tend to be monogamous—less destructive waste.
Additionally I can imagine societies with high levels of polygyny (think emperors with giant harems) could be extremely unstable due to sexual jealousy, but that’s mere speculation.
Apologies if this has already been posted—I was late to this thread and there’s an unmanageable number of comments to search through.
