Explaining large-N cooperation: Generalized social trust and the social exchange heuristic

This paper presents a new argument that links generalized social trust and collective action in situations with a large number of actors who do not have specific information on each other. Generalized social trust enhances large -N cooperation through the social exchange heuristic, which stimulates conditional cooperation in social dilemmas. Using data from a survey in four countries and recycling behavior as an indicator of collective action, this explanation is tested with individual-level data. While the relationship between generalized social trust and large -N collective action is often hypothesized, there is scant micro-level evidence as it has mainly been tested at the macro level. The results show that people holding generalized social trust cooperate more readily in large -N dilemmas, and that they most likely do so because of the social exchange heuristic.
