In their experiment, they put students in a prisoners' dilemma game. But unlike the usual dilemma, in some treatments they told one side what the other side had done. When students were told that the other side had defected on them, only 3 percent responded with cooperation. When told that the other side had cooperated, this increased cooperation levels to 16 percent. [...]
What do you think would happen when the students were not told anything about the other player's choice at all? Would the percentage of cooperators be between 3 and 16 percent? No; it rose to 37 percent.
