Suspicion and communication
通过发送者-接收者实验，研究沟通如何影响接收者的猜疑程度，发现沟通总体上显著降低猜疑，但部分接收者反而更猜疑，并用机器学习分析聊天记录来区分这些效应。
In this paper, we study how communication influences suspicion. The experiment uses a sender–receiver setup with a low probability of misaligned incentives for senders and receivers. We focus on the impact of open communication on the receivers’ suspicion as measured by the size of the deviation from the senders’ recommendation before and after the communication. Overall, communication substantially reduces suspicion, but some receivers become more suspicious during the communication. We disentangle these effects using machine learning methods to analyze the chat logs.
