Uncertainty and prejudice : the role of religiosity in shaping group attitudes

Past research indicates that being religious is frequently motivated by the need to avoid uncertainty, and associated with prejudice against value-violating groups. The present research clarifies these previous findings and shows for the first time a causal link between a sense of uncertainty and group attitudes through religiosity and the perception of the target group's mindset. Study 1 demonstrates that belief in God is associated with uncertainty avoidance, and increases prejudice against value-violating groups, but simultaneously increases positive attitudes towards value-consistent groups. Study 2 demonstrates experimentally that a sense of uncertainty shapes intergroup attitudes when the relationship is mediated through the belief in God, and the perception that a target group actually violated perceiver's values. The results corroborate and broaden previous findings on religiosity, ambiguity avoidance and prejudice, and for the first time show a causal link between a sense of uncertainty and attitudes towards value-violating and value-consistent groups
