This paper investigates how communication influences people’s judgment quality in simple estimation tasks. Except for an exchange of estimates, our design also allows the exchange of supportive evidence underlying the estimates in a controlled manner. Compared with the control treatment, the exchange of estimates and supportive evidence together improves judgment quality at both the individual level and the crowd level. On the other hand, the exchange of estimates or supportive evidence separately has no impact.

该说些什么？明智的沟通和明智的人群

本文研究了沟通如何在简单的评估任务中影响人们的判断质量。除了交换估计值之外，我们的设计还允许以受控方式交换估计值背后的支持证据。与对照治疗相比，评估和支持证据的交换共同提高了个人水平和人群水平的判断质量。另一方面，分别交换估计数或支持性证据没有影响。
