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.[2][3][4] The correlation is especially strong between religious fundamentalism (defined as belief in an "inerrant set of religious teachings") and authoritarianism, both of which are characterized by low openness to experience, high rigidity, and low cognitive complexity.[2] In particular, authoritarianism "is positively associated with a religion that is conventional, unquestioned, and unreflective".[2][3]
