Does moral culture contribute to the evolution of cooperation? Here, we examine individuals’ and communities’ models of what it means to be good and bad and how they correspond to corollary behavior across a variety of socioecological contexts. Our sample includes over 600 people from eight different field sites that include foragers, horticulturalists, herders, and the fully market-reliant. We first examine the universals and particulars of explicit moral models. We then use these moral models to assess their role in the outcome of an economic experiment designed to detect systematic, dishonest rule-breaking favoritism. We show that individuals are slightly more inclined to play by the rules when their moral models include the task-relevant virtues of “honesty” and “dishonesty.” We also find that religious beliefs are better predictors of honest play than these virtues. The predictive power of these values’ and beliefs’ local prevalence, however, remains inconclusive. In summary, we find that religious beliefs and moral models may help promote honest behavior that may widen the breadth of human cooperation.

Citizen-based accountability strategies to improve the lives of the poor and marginalized groups are increasingly being used in efforts to improve basic public services. The latest thinking suggests that broader, multi-pronged, multi-level, strategic approaches that may overcome the limitations of narrow, localized successes, hold more promise. This paper examines the challenges and opportunities, in theory and practice, posed by the integration of two such citizen-based accountability strategies—social accountability and legal empowerment. It traces the foundations of each of these approaches to highlight the potential benefits of integration. Consequently it examines whether these benefits have been realized in practice, by drawing upon five cases of organizations pursuing integration of social accountability and legal empowerment for health accountability in Macedonia, Guatemala, Uganda, and India. The cases highlight that while integration offers some promise in advancing the cause of social change, it also poses challenges for organizations in terms of strategies they pursue.
