Jared Diamond: Why do societies collapse?

Growing old in traditional societies

Jared Diamond is the author of Guns, Germs, and Steel, which was a provocative answer to the question of why Europe dominated the world for much of recent history. More recently, he has written The World Before Yesterday, an investigation of traditional societies, and what the modern world might learn from them.

For this talk, he’s focusing on one chapter of that book and asking the question: what can we learn about how to treat elderly people from traditional societies? There are many, many traditional societies, and they are very different from modern societies. “Tribes,” says Diamond, “constitute thousands of natural experiments in how to run a society.” He is quick to add that they shouldn’t be scorned as primitive, nor romanticized as happy and peaceful.

Now in our society, most old people end up living separately from their children, and away from the friends they grew up with. In traditional societies everyone lives out their lives among their children and friends. That said, their treatment varies wildly.

At the worst extreme, many get rid of the elderly by one of several methods:

This happens, says Diamond, mainly under two conditions: Nomads that are incapable of physically carrying them, or people living in marginal or fluctuating environments, such as the arctic or deserts. To us it sounds horrible, “But what could those traditional societies do differently?”

On the opposite extreme are the New Guinea farming societies he has been studying recently and most other sedentary farming societies. There the elderly are fed, remain and live in the same hut or a nearby hut to their children.

What does this mean?

There are two reasons for this variation, the usefulness of old people and the society’s values. There are many things that elderly people contribute to their societies: They may be effective in producing food. They can babysit grandchildren, freeing their children to hunt and gather. They can craft things. And often they are the leaders and the most knowledgeable. The last point has a huge significance that would never occur to us in literate societies, “It’s their knowledge that spells the difference between survival and death.” In other cases, the society places an emphasis on respect for the elderly, as in East Asia. That contrasts strongly with the United States. Here, the elderly are at a huge disadvantage. For example in job applications, or in hospitals — in that case there is an explicit policy to treat younger people first.

There are several reasons for that low status: The Protestant work ethic, the emphasis on self-reliance and indepenence, and the cult of youth. Clearly, there have been many changes for the better, but there have also been changes for the worse:

The lessons

This is clearly a huge problem, but Diamond thinks there are a few good takeaways from traditional societies about the value of our elders:

It’s a lot of food for thought. Diamond reminds us that we should consider, without romanticizing, that, “Traditional society elders have traditionally more rich lives. They think of dangers far less than we do, and they don’t die of heart disease and diabetes.”
