Research Suggests Polygamous Men Live Longer

Calopteryx writes "Want to live a little longer? Get a second wife. A study reported in New Scientist suggests that men from polygamous cultures outlive those from monogamous ones. After accounting for socioeconomic differences, men aged over 60 from 140 countries that practice polygamy to varying degrees lived on average 12% longer than men from 49 mostly monogamous nations."

You have a big problem here.

Read the summary of the study's conclusion again. What the study claims to demonstrate isn't that polygamists live longer than other men in their own society; what it demonstrates is that in societies where a minority of the men have multiple wives, the mean longevity of all men is longer.

Note the following two things that follow from this:

1. It hasn't been demonstrated that the extra mean longevity in the population as a whole is due to the extra longevity of the polygamists. Nobody's gonna be surprised if more research shows that is the case, but let's not get ahead of ourselves
2. Far more importantly, if it is indeed the case that the small number of polygamists truly does push up the average life expectancy of the whole community, this means that the men who don't have multiple wives aren't pulling it down.

The second point I just made is at odds with what you're telling us here:

On the flipside, look at the polygamist societies - in Middle Eastern/African muslim societies, those who aren't going to reach 60 (read: the poor) usually kill themselves off FAR faster in various tribal conflicts and wars.

For this to be consistent with the results of the study, the negative effect of such early deaths on average longevity must be smaller than the positive effect that the polygamists have on the same statistic. Which suggests you're totally overblowing this by reasoning on the basis of stereotypes.
