Measuring trust: A reinvestigation

We reinvestigate the question first posed by Glaeser et al. (2000): Do survey measures about trust predict actual trusting behavior? This important study established that the behavior in an incentivized trust game is not correlated with the responses to the most widely used survey measures of trust. We conduct a replication and a reinvestigation of GLSS. In the replication, we use the GLSS protocol and we reproduce their results. In the reinvestigation, we introduce one major change: We replace their variation of the standard Berg, Dickhaut, and McCabe (1995) investment game with the original unmodified game. The standard game endows both players, while the modified version endows only the first mover. After endowing both movers in the reinvestigation experiment, we find a significant correlation between the two measures, suggesting that trust is a single construct, whether measured by the survey questions or by an incentivized trust game.
