Political Corruption and Social Trust: An Experimental Approach

Abstract

The main question addressed in this paper is how the great variation in the level of social trust in different countries can be explained. Most empirical research on this question has been based on survey data which has limitations when it comes to capturing the causal mechanisms. Building on theories that point to the importance of trustworthy governmental institutions for creating social trust, two parallel experiments were conducted in two countries where the levels of corruption and social trust are very different. One group of 64 Swedish and one group of 82 Romanian undergraduate students responded to a number of scenarios which describe situations at a police station or a doctor's surgery in a foreign country. The results supported the hypothesis that trust in authorities influences the perceptions of the trustworthiness of others in general. Even though some of the effects were stronger for one sample than for the other, the influence of vertical trust on social trust was true for both the high- and the low-trusting sample.
