Kindness Breeds More Kindness

A study, published March 8 in the Proceedings of the National Academy of Sciences, shows that goodness spurs goodness: A single act can influence dozens more. In a study designed to see whether tiny acts of kindness have larger consequences, the researchers have shown that generosity is contagious.
This was done via a small game in which people were divided into groups of four, given 20 credits each, and asked to secretly decide what to keep for themselves and what to contribute to a common fund. That fund would be multiplied by two-fifths, then divided equally among the group. The best payoff would come if everyone gave all their money — but without knowing what others were doing, it always made sense to keep one’s money and skim from the generosity of others.
Only at the end of each game did players find out what the rest of their group had done. The game was run again and again, each time mixing group members and keeping their identities anonymous, so that decisions were never personal.
And when one person gave, others in their group tended to be generous during the next two rounds of play. Recipients of their largess became more generous in turn, and so on down the chain. When a punishment round was added — players could spend their own money to reduce the rewards of selfish players — generosity lasted even longer.
According to the the researchers, the explanation lies not in calculations of odds and rewards, but in simple behavioral mimicry: Monkey see, monkey do, human style. When people are irrationally generous, others follow suit.
