The present study examines whether collaborative situations make individuals more dishonest. It also considers how this dishonesty unfolds over time. To address these questions, we employed a sequential dyadic die-rolling task in which two participants in a pair receive a payoff only if both report the same die-roll outcome. On each trial, one participant (role A) rolled a die first and reported the outcome. Then, the second participant (role B) was informed of A’s reported number, rolled a die as well and reported the outcome. If their reported outcomes were identical, both of them received a reward. We also included an individual condition in which an individual subject rolled a die twice and receive a reward if he/she reported the same die-roll outcome. We found that B lied significantly more than participants in individual condition, whereas A lied as much as participants in individual condition. Furthermore, when collaborating, more and more participants (both A and B) became dishonest as the game progressed, whereas there was no such trend among participants during the individual condition. These findings provide evidence indicating that collaborative settings increase dishonesty and that this effect becomes more evident as the collaboration progress.

协作设置会增加不诚实

本研究研究了协作情况是否使个人更不诚实。它还考虑了这种不诚实随着时间的流逝如何发展。为了解决这些问题，我们采用了顺序二元模切轧制任务，其中只有两个参与者都报告相同的模切轧制结果时，一对参与者中的两个参与者才能获得回报。在每个试验中，一个参与者（角色A）首先掷骰子并报告结果。然后，第二个参与者（角色B）被告知A的报告数字，也掷骰子并报告了结果。如果他们报告的结果相同，则他们俩都会获得奖励。我们还包括一个个体条件，其中个体受试者两次掷出骰子，如果他/她报告了相同的掷骰结果，则获得奖励。我们发现B在个人情况下的说谎人数远多于参与者，而A会根据参与者的个人情况撒谎。此外，在进行协作时，随着游戏的进行，越来越多的参与者（A和B）变得不诚实，而在个体情况下参与者之间没有这种趋势。这些发现提供了证据，表明协作环境增加了不诚实，并且随着协作的进行，这种影响变得更加明显。
