Measuring Trust*
通过两个实验和一个调查测量信任与可信度，发现调查问题更能预测可信行为，而信任行为由过去的信任经历预测；社会距离近则两者上升，不同种族或国籍时可信度下降。
We combine two experiments and a survey to measure trust and trustworthiness—two key components of social capital. Standard attitudinal survey questions about trust predict trustworthy behavior in our experiments much better than they predict trusting behavior. Trusting behavior in the experiments is predicted by past trusting behavior outside of the experiments. When individuals are closer socially, both trust and trustworthiness rise. Trustworthiness declines when partners are of different races or nationalities. High status individuals are able to elicit more trustworthiness in others.
