Trust and the risk of consuming polluted water in Shanghai, China

It is commonly understood that political trust reduces public perceptions of various kinds of risk. However, this knowledge largely comes from research conducted in liberal democratic states, and so may have little explanatory power in China. Though it has an authoritarian government, China has enjoyed relatively high levels of political trust, and so is a unique case from which to advance knowledge about political trust and risk perception. We describe the relationship between risk perception and political trust in China through analysis of results from a survey of 5007 residents in Shanghai asking about people’s perceptions of the risk of consuming tap water (a key public good), and their levels of trust in the public water authorities. Findings reveal that political trust in general, and trust in the perceived fairness, honesty and capability of water authorities significantly reduces the perception of the risk of consuming tap water. This suggests that the inverse relationship between trust and risk perception applies regardless of whether a society is democratic or authoritarian.
