Social dominance orientation (SDO) is one of the most powerful predictors of intergroup attitudes and behavior. Although SDO works well as a unitary construct, some analyses suggest it might consist of two complementary dimensions--SDO-Dominance (SDO-D), or the preference for some groups to dominate others, and SDO-Egalitarianism (SDO-E), a preference for nonegalitarian intergroup relations. Using seven samples from the United States and Israel, the authors confirm factor-analytic evidence and show predictive validity for both dimensions. In the United States, SDO-D was theorized and found to be more related to old-fashioned racism, zero-sum competition, and aggressive intergroup phenomena than SDO-E; SDO-E better predicted more subtle legitimizing ideologies, conservatism, and opposition to redistributive social policies. In a contentious hierarchical intergroup context (the Israeli-Palestinian context), SDO-D better predicted both conservatism and aggressive intergroup attitudes. Fundamentally, these analyses begin to establish the existence of complementary psychological orientations underlying the preference for group-based dominance and inequality.
社会支配倾向（SDO）是群体间态度和行为的最有力预测因素之一。尽管 SDO 作为一个单一结构表现良好，但一些分析表明，它可能由两个互补的维度组成——SDO-支配（SDO-D），即偏好某些群体支配其他群体，以及 SDO-平等主义（SDO-E），即偏好非平等主义的群体关系。作者使用来自美国和以色列的七个样本，证实了因素分析的证据，并展示了两个维度的预测有效性。在美国，SDO-D 被理论化并发现与旧派种族主义、零和竞争和攻击性群体现象比 SDO-E 更相关；SDO-E 更好地预测了更微妙的合法化意识形态、保守主义和反对再分配社会政策。在一个有争议的等级群体间背景（以色列-巴勒斯坦背景）中，SDO-D 更好地预测了保守主义和攻击性群体态度。从根本上说，这些分析开始建立起在基于群体的支配和不平等偏好背后存在互补的心理倾向。
