Although religiosity correlates positively with authoritarianism, the temporal ordering of this relationship is unclear. Because religious teachings often promote authoritarian values, right-wing authoritarianism (RWA) should increase following religious conversion. Yet spiritual beliefs may also promote egalitarianism. As such, social dominance orientation (SDO) might decrease postconversion. We tested these hypotheses using data from a subset of participants who converted to Christianity at some point during a 9-year longitudinal panel study (N = 536). We also examined a separate subsample who deconverted over the same period (N = 696). As hypothesised, RWA was stable before conversion, but increased slightly after becoming religious. Unexpectedly, SDO was stable both pre- and postconversion. Conversely, those who deconverted from Christianity experienced declines in RWA both before and after losing their religion, whereas SDO declined only postdeconversion. These results suggest that religious conversion precedes increases in RWA (but not SDO), and that declines in RWA precede deconversion.
