Ideology and climate change denial

Examining the relation between ideological variables and climate change denial, we found social dominance orientation (SDO) to outperform right-wing authoritarianism and left–right political orientation in predicting denial (Study 1 and 2). In Study 2, where we experimentally altered the level of denial by a newscast communicating supporting evidence for climate change, we demonstrated that the relation between the ideology variables and denial remains stable across conditions (newscast vs. control). Thus, the results showed that denial can be altered by communicating climate change evidence regardless of peoples’ position on ideology variables, in particular social dominance. We discuss the outcome in terms of core elements of SDO – dominance and system-justification motives – and encourage researchers on climate change denial to focus on these elements.
