Why Does Involvement in Voluntary Associations Promote Trust? Examining the Role of Network Diversity

Abstract

Scholars argue that trust is fundamental to maintaining a healthy society, and consequently, recent evidence that trust may be declining in the United States has generated an interest in the determinants of trust. According to the social capital literature, particularly the work of Robert Putnam, involvement in voluntary associations influences the development of generalized trust. One way in which organizational participation is thought to foster trust is through creating more diverse, or bridging, social networks. However, scarcely any research has empirically examined this mechanism. Using data from the Social Capital Community Benchmark Survey, I test whether network diversity (ties to persons from different social backgrounds) accounts for some of the influence of organizational involvement on trust. The results suggest that the influence of involvement in multiple associations on trust is largely mediated by its influence on network diversity. In addition, while recent research observes that some predictors of trust vary by race and ethnicity, I find no differences in these relationships across non-Hispanic white, African American, and Latino respondents.
