Evolutionary models and empirical evidence indicate that such altruistic punishment has been a decisive force in the evolution of human cooperation. We used H<sub>2<\/sub> <sup>15 <\/sup>O positron emission tomography to examine the neural basis for altruistic punishment of defectors in an economic exchange. Subjects could punish defection either symbolically or effectively. Symbolic punishment did not reduce the defector\u2019s economic payoff, whereas effective punishment did reduce the payoff. We scanned the subjects\u2019 brains while they learned about the defector\u2019s abuse of trust and determined the punishment. Effective punishment, as compared with symbolic punishment, activated the dorsal striatum, which has been implicated in the processing of rewards that accrue as a result of goal-directed actions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>New brain research reveals why we\u2019re willing to go out of our way to punish people who break the rules, even when it costs us time, money, or friends.
