Abstract for that article is nonsense. If you have access, read the data. I’ll summarize.
His group and he played the Ultimatum Game in many different places: A person given ten dollars must decide what proportion to split the money in. If the second person refuses, they both get nothing.This is, of course, costly, because the second person when he refuses what is free money gets nothing.
What they found was that propensity for costly punishment varies very greatly across the world.
What I find interesting/disturbing is that people in the United States, and many parts of the developed world, often require must closer to a 50% split than so-called ‘primitive-communists’, such as amazonian tribes. In other words, people in the US think there is a Right to Fairness in income distribution, such they they refuse free money, just so other people won’t get more money than they do.
In other words, students in the US are increasingly acting like communists in anonymous situations, whereas tribesmen in Africa and South America think costly punishment is silly in anonymous situations. A total reverse often to what Marx predicted. (Henrich has another article that is more revealing in the American Economic Review, because he asks people why they did or did not refuse a particular split).
“Fairness”, with all its implications, against free market varies very widely. Its a self-reinforcing cultural norm, but only where it exists. Furthermore, instead of forwarding cooperation, we see it prevents it.
