Religion and authoritarianism
Most measures of religiosity, such as church attendance and affiliation, are positively correlated with the authoritarian personality cluster, which includes submission to authority, conventionality, and intolerance of out-groups. The correlation is especially strong between religious fundamentalism and authoritarianism, both of which are characterized by low openness to experience, high rigidity, and low cognitive complexity. In particular, authoritarianism "is positively associated with a religion that is conventional, unquestioned, and unreflective".
Background
Hundreds of scientific articles have been published investigating the connections between religion and authoritarianism. There is a distinction between psychology, which treats authoritarianism as innate to the personality, and sociology, which considers authoritarianism a result of one's environment and posits that it may be influenced by factors such as religion.A longitudinal study of Americans born in the 1920s found that this effect held for traditional church-centered religion but not for those that are seeking non-institutional spirituality. The latter mode of religion is "characterized by an openness to new experiences and by creativity and experimentation, characteristics that are antithetical to the conventionality that adheres in authoritarianism".
