Need for cognitive closure and political ideology predicting pro-environmental preferences and behavior

Little is known about epistemic motivations affecting political ideology when people make environmental decisions. In two studies, we examined the key role that political ideology played in the relationship between need for cognitive closure (NCC) and self-reported ecofriendly behavior. Study 1: 279 participants completed the NCC, pro-environmental, and political ideology measures. Mediation analyses showed that NCC was related to less pro-environmental behavior through more right-wing political ideology. Study 2: We replicated these results with a nonstudent sample (n = 240) and both social and economic conservatism as mediators. The results of Study 2 showed that social conservatism mediated the relationship between NCC and pro-environmental behavior. Finally, NCC was associated with proenvironmental attitude through both social and economic conservatism.
