Lying involves many decisions yielding big or small benefits. Are big and small lies complementary or supplementary? In a laboratory experiment where the participants could simultaneously tell a big and a small lie, our study finds that lies are complementary. The participants who lie more in the big lie, also do so in the small lie and vice versa. Our study also finds that although replacing one dimension of the lying opportunities with a randomly determined prize does not affect the overall lying behavior, repeatedly being lucky on a high-stakes prize leads to less lying on the report of a low-stakes outcome.

大大小小的谎言

说谎涉及许多产生或大或小的收益的决定。大大小小的谎言是互补的还是互补的？在一项实验中，参与者可以同时讲出一个大的和一个小的谎言，我们的研究发现，谎言是互补的。在大谎言中说谎更多的参与者，也在小谎言中说谎，反之亦然。我们的研究还发现，尽管用随机确定的奖品代替撒谎机会的一个维度不会影响整体的撒谎行为，但屡次在高风险奖品上幸运会减少对低风险结果报告的说谎。
