Trust and Promises over Time
通过大规模混合实验室和在线信任实验，研究时间推移如何影响信任，发现沟通（主要是承诺）能将合作、信任和可信度提高约50%，即使延迟三周仍有效。
Using a large-scale hybrid laboratory and online trust experiment with and without preplay communication, we investigate how the passage of time affects trust. Communication (predominantly through promises) raises cooperation, trust, and trustworthiness by about 50 percent. This result holds even when three weeks pass between the time of the trustee’s message/the trustor’s decision to trust and the time of the trustee’s contribution choice and even when this contribution choice is made outside of the lab. Delay between the beginning of the interaction and the time to reciprocate neither substantially alters trust or trustworthiness nor affects how subjects communicate.
