Are humans cruel to be kind? – life – 16 May 2009 – New Scientist

Interesting experiment into our natural tendency to be cruel.

“Last year Karla Hoff, an economist at the World Bank who is currently working at Princeton University, and her colleagues reported the results of experiments conducted in villages in the Indian state of Uttar Pradesh (American Economic Review, vol 98, p 494). In these tests, two players started out with 50 rupees each. The first could choose to give his to the second, in which case the experimenters added a further 100 rupees, giving the second player 200 rupees in total. The second player could decide to keep the money for himself, or share it equally with the first player. A third player then entered the game, who could punish the second player – for each 2 rupees he was willing to spend, the second player was docked 10 rupees.

The results were startling. Even when the second player shared the money fairly, two-thirds of the time the newcomer decided to punish him anyway – a spiteful act with seemingly no altruistic payoff. “We asked one guy why,” says Hoff. “He said he thought it was fun.””
