In Brief: The social voice of conscience
The social voice of conscience
"Conscience is the still, small voice that tells you someone may be watching," according to a cynical aphorism. A series of psychological experiments in various cultures suggests that, properly interpreted, this aphorism states a less cynical truth. Altruism or willingness to share is not just a charitable impulse. It is associated with willingness to pay a price to penalize others for not sharing.
More than 1,700 people in 15 cultures from Africa, South America, New Guinea, the South Pacific, and the American Midwest played three simple experimental "games" called the ultimatum game, the dictator game, and the third-party punishment game.
