In this article, we examine the roles of social dominance orientation (SDO) and ecological dominance orientation (EDO) as predictors of climate change risk and threat perceptions and associated pro-environmental policy support. EDO is a novel measure that we devised based on social dominance theory to assess general preferences for an anthropocentric, hierarchical arrangement between humans, non-human animals, and the natural environment. Across two pre-registered studies (N = 715; USA and Germany) our results indicate that SDO and EDO are uniquely associated with decreased support for climate change mitigation policies benefitting humans, non-human animals, and the natural environment. These relationships in turn are partially mediated by decreased climate change risk and threat perceptions. We successfully replicate our findings using a more behavioral measure as dependent variable. Notably, using a more behavioral measure (Study 2), EDO was significantly associated with pro-environmental behavior but not SDO, when threats are accounted for as mediators.

在本文中，我们研究了社会主导导向 (SDO) 和生态主导导向 (EDO) 作为气候变化风险和威胁感知以及相关的环保政策支持的预测因子的作用。EDO 是我们根据社会支配理论设计的一种新措施，用于评估人类、非人类动物和自然环境之间以人类为中心的等级安排的一般偏好。跨越两项预先注册的研究（N= 715; 美国和德国）我们的结果表明，SDO 和 EDO 与减少对气候变化减缓政策的支持有关，这些政策有利于人类、非人类动物和自然环境。反过来，这些关系在一定程度上是由气候变化风险和威胁感知的减少所调节的。我们使用更多行为测量作为因变量成功地复制了我们的发现。值得注意的是，使用更多行为测量（研究 2），当威胁被视为中介时，EDO 与亲环境行为显着相关，但与 SDO 无关。
