三个实验测试了自我损耗对经济决策的影响。参与者完成了一项需要或不需要自我控制的任务。然后，参与者学习了信任游戏，在这个游戏中，发送者会得到一笔10美元的初始资金，在他们自己和另一个接收者之间分配。接收方收到三倍的金额，可以将三倍的钱中的任何一笔、全部或一笔都寄回给发送方。参与者被分配了发送者的角色，并决定如何分配初始分配。少给钱，也就是不信任收款人，是一种安全、风险更小的回应。那些自我控制能力强的参与者给接收者的钱比那些没有耗尽的参与者少（实验1）。这一效应在另外两个实验中得到了重复和缓和。耗尽再次导致捐赠金额减少（信任度降低），但主要是在那些被告知永远不会见到接受者（实验2）或没有被告知他们与接受者有多相似（实验3）的参与者中。对于希望见到接受者（实验2）或被引导相信他们与接受者非常相似（实验3）的穷尽和非穷尽参与者，给予的金额没有差异。在精疲力竭的参与者中，信任度下降在神经症患者中最为明显。这些结果表明，自我控制促进了行为信任，尤其是在没有其他线索表明信任的社会风险降低的情况下，比如与接受者建立了实际或可能的关系。
Three experiments tested the effects of ego depletion on economic decision making. Participants completed a task either requiring self-control or not. Then participants learned about the trust game, in which senders are given an initial allocation of $10 to split between themselves and another person, the receiver. The receiver receives triple the amount given and can send any, all, or none of the tripled money back to the sender. Participants were assigned the role of the sender and decided how to split the initial allocation. Giving less money, and therefore not trusting the receiver, is the safe, less risky response. Participants who had exerted self-control and were depleted gave the receiver less money than those in the non-depletion condition (Experiment 1). This effect was replicated and moderated in two additional experiments. Depletion again led to lower amounts given (less trust), but primarily among participants who were told they would never meet the receiver (Experiment 2) or who were given no information about how similar they were to the receiver (Experiment 3). Amounts given did not differ for depleted and non-depleted participants who either expected to meet the receiver (Experiment 2) or were led to believe that they were very similar to the receiver (Experiment 3). Decreased trust among depleted participants was strongest among neurotics. These results imply that self-control facilitates behavioral trust, especially when no other cues signal decreased social risk in trusting, such as if an actual or possible relationship with the receiver were suggested.
