Secularism, sorting, and Americans’ political knowledge

Abstract Political knowledge, including knowledge of basic civics and current political conditions, is associated with a host of pro-democratic outcomes including institutional trust and civic and political participation. Religion is also historically associated with these outcomes, yet a link between religion and indicators of political knowledge remains underexamined. Integrating research on religion/secularism and political engagement with work on partisan sorting, I theorize self-consciously secular Americans, particularly if they are sorted politically, will exhibit the strongest grasp on basic civics and current political conditions. Analyses of data from a recent, nationally representative survey affirm my expectations. Self-identified atheists/agnostics consistently score significantly higher than religious or non-affiliated Americans on questions about basic civics and current political conditions. Interactions reveal that education helps most other religious groups catch up to atheists/agnostics on civics knowledge, but not knowledge about current politics. And on knowledge of both basic civics and current politics, atheists/agnostics’ advantage is strongest among liberals and Democrats and disappears among conservatives and Republicans. A similar pattern appears for evangelical Protestants in the opposite direction with their scores on both civics and current politics increasing significantly as they identify more with ideological conservatism, but this does not apply to partisan identity. Findings extend literatures on political knowledge, religious/secular political engagement, and partisan sorting by showing that (1) self-identified secular Americans, particularly if they are sorted, tend to be the most knowledgeable about basic civics and current political conditions, and (2) this pattern is to a weaker extent mirrored by evangelicals, another politicized religious group.
