Financial TimesKindness down to social forcesEvolutionary biology alone cannot explain why people in modern societies are frequently kind and helpful to strangers, even though they derive no personal benefit and may even suffer for their altruism. A large study shows that, as communities grow larger, social forces such as religion and market systems become more important in controlling co-operative behaviour.
The research, published in the journal Science, looked at the behaviour of people in 15 societies, from New Guinea to North America, when playing three well-known economic games (called Ultimatum, Dictator and Third-Party Punishment).
According to the results, people in small, traditional societies that are not involved in world religions and do not have organised market systems are much less concerned with fairness than their counterparts who are part of the global economy and are influenced by religion. They are less likely to “play fair” in the games and also less likely to punish other players who cheat in the game.
“Our results contradict previous theories that humans learned to treat strangers fairly by transferring behaviour and norms developed in their actions and attitudes toward family and kin,” said Joe Henrich of the University of British Columbia, the study leader. “Small-scale communities have local norms governing all kinds of interactions, but they often don’t have default social norms of dealing with strangers or anonymous others in monetary transactions.”
