This chapter explores the complex relationship between religiosity and human rights. Publics in Mexico, Morocco, India, and Nigeria are deeply religious, yet human rights practitioners struggle to identify the most effective methods to engage with religious worldviews and institutions. The chapter presents evidence for human rights conceptualizations that are unique to particular religious traditions. For example, Catholics are more likely to have positive associations with human rights than non-Catholics, and Muslims tend to associate “human rights” with “women’s rights” more than non-Muslims. Data also suggest that social religiosity, such as regular attendance in a place of worship, is associated with more negative ideas about human rights, whereas personal religiosity, such as practices of prayer, is linked to more positive ideas. Religion and human rights are strongly linked, but in multidirectional or seemingly contradictory ways, suggesting the need for context- and issue-sensitive future research.
