Cognitive and personality correlates of trait disgust and their relationship to condemnation of nonpurity moral transgressions

Past research has found that individuals who are more sensitive to physically disgusting stimuli also condemn moral transgressions more harshly. However, there is debate about whether this condemnation includes transgressions that do not involve impure behaviors. We present a meta-Analysis of 6 studies (N - 1082) which suggests that trait disgust is associated with condemnation of nonpurity transgressions. This relationship was primarily explained by sensitivity toward the very core disgust stimuli that those transgressions lack. We next tested whether this relationship might be mediated by a third variable. We found that trait core disgust was associated with higher orderliness, lower deviance sensitivity, and preference for intuitive thinking; these variables also correlated with moral condemnation. Trait disgust was also associated with lower generalized social trust, but trust was not correlated with moral condemnation. Neither trait disgust nor moral condemnation were associated with ethnocentrism. Further, none of these variables mediated the relationship between trait disgust and condemnation. Taken together, our results support a role for trait disgust in moral judgments outside of the purity domain, but leave unexplained its association with condemnation of nonpurity transgressions

An orderly personality partially explains the link between trait disgust and political conservatism

Individuals who are more easily disgusted tend to be more politically conservative. Individuals who have a preference for order also tend to be more politically conservative. In the present research, we hypothesised that these three variables are psychologically interrelated. Specifically, trait disgust encourages a generalised search for order, which, in turn, encourages the endorsement of political positions that aim to maintain societal order. Taking an individual differences approach, we operationalised the preference for order via Orderliness, one aspect of the Big Five trait Conscientiousness. Across six samples (total N = 1485), participants completed measures of trait disgust, aspect/trait personality, and political orientation. Analyses revealed that Orderliness was a consistent mediator of the association between trait disgust and conservatism. Analyses of subscales of disgust revealed preliminary evidence that Orderliness most consistently mediated the relationships between Contamination, Pathogen, and Sexual disgust and conservatism. These data suggest that disgust-sensitive people extend their preference for order in the physical environment (e.g. tidying up one's room) to the sociopolitical environment (e.g. strengthening traditional norms). The present findings illustrate one way in which emotional, cognitive, and personality processes work together to influence political orientation
