Searching for certainty: Religious beliefs and intolerance toward value-violating groups

Religiosity has been consistently linked to prejudice toward a variety of outgroups. This article proposes that this is the case only when religiosity reflects a specific aspect of seeking guidance and security in daily practices and complex sociocultural norms. Outgroups that challenge the epistemic certainty that belief in God provides are rejected in an effort to protect this certainty. The results from two studies found that uncertainty avoidance was related to belief in God and this belief mediated the relationship between uncertainty avoidance and intolerance within the context of general human rights (Study 1), and the derogation of value-violating groups (e.g., homosexuals or followers of other religions) but not of groups that pose no threat to religious values (old or poor people) (Study 2). The interpretative dimension of religiosity (i.e., the way in which people process religious content) is not connected to security seeking, as reflected in the lack of a correlation with uncertainty avoidance and with different prejudice measures. The results are discussed in relation to past research on religiosity and prejudice, and suggest that for people who avoid uncertainty, only those types of religious beliefs that provide a sense of certainty are linked with intolerance toward value-violating groups.
