Utilitarian or deontological models of moral behavior—What predicts morally questionable decisions?
通过投票游戏实验,研究了人们在撒谎和挪用捐款等道德有问题的决策中,是遵循功利主义还是义务论道德模型,发现撒谎更符合温和义务论,而挪用捐款更符合温和功利主义。
The distinction between consequentialism and deontologism is fundamental for moral philosophy and has also attracted attention in the economic analysis of moral decisions. We consider voting games where people can earn money by taking morally questionable decisions. Our predictions are taken from a simple behavioral game-theoretic model and depend on the underlying moral preferences. For both kinds of moral theories, we consider a strict and a moderate version. Moral absolutism prohibits certain behavior under any circumstances. Moderate deontologists face internal moral costs whenever they violate a norm but take trade-offs with consequences into account. Strict consequentialists care only about consequences. Moderate consequentialists face moral costs from violating a norm if and only if their violation yields negative consequences for others. We test our predictions experimentally for lying on the outcome of a lottery and taking money designated for donation. Our data support moderate deontologism for lying and moderate consequentialism for donation. We attribute this to telling the truth being a duty which, if violated, always leads to moral costs, while voting for taking the money yields moral costs if and only if people actually get it.
