Dishonesty and charitable behavior
通过实验室实验，研究未来有机会捐赠是否增加当前作弊行为，以及过去道德选择如何影响捐赠，发现知晓可捐赠时作弊更多、捐赠更少，并提出社会规范违反会麻木良心的假说。
Abstract We examine in the laboratory how having the opportunity to donate to a charity in the future affects the likelihood of engaging in dishonest behavior in the present. We also examine how charitable donations are affected by past ethical choices. First, subjects self-report their performance on a task, which provides them with an opportunity for undetected cheating. In the second stage they can donate some of the money earned in the first stage to a charity. Only subjects in the treatment group know about the opportunity to donate in the second stage. We find that more subjects cheat if they know they can donate some of the money to charity. We also find that subjects in treatment end up donating less to charity and that both honest and dishonest subjects donate less in treatment. We propose a new hypothesis that explains these results: past violations of social norms numb one’s conscience, leading to more antisocial behavior.
