Interpersonal trust is a strong predictor of health and happiness. However, there is more to be learned about how various forms of trust boost well-being. For example, trust in known others like family and friends and trust in strangers are likely to have different consequences of well-being. Furthermore, beyond individuals' sense of trust in various others, the level of trust in communities is consequential. This project seeks to understand the mechanisms that link various forms of trust to well-being. In addition, we will investigate differences across groups and countries in the benefits of individual-level trust. Finally, we will investigate potential inequality in who benefits from levels of community trust.
