In this study we analyze distinct socio-political predictors, namely, system justification, moral foundations, political ideology, social dominance orientation and authoritarianism, of two distinct but interrelated postcolonial ideologies, namely symbolic exclusion and historical negation in regards to the Mapuche people, in a sample of the general Chilean population (n = 1.242). According to the results, symbolic exclusion is explained by the political ideology of the participants, their social dominance orientation, right-wing authoritarianism, system justification and one specific moral foundations’ dimension: harm/care. On the other hand, right-wing authoritarianism, system justification, political ideology, and two specific moral foundations (loyalty/betrayal and authority/subversion) play an important role in predicting the historical negation of negative events affecting the Mapuche Indigenous people in Chile. Our results are discussed in terms of their implications for present-day intergroup relations between the Mapuche and non-Indigenous Chileans.

在这项研究中，我们分析了两种截然不同但相互关联的后殖民意识形态的不同社会政治预测因素，即系统正当性、道德基础、政治意识形态、社会支配取向和威权主义，即对马普切人的象征性排斥和历史否定。智利总人口的样本（n = 1.242)。结果表明，象征性排斥可以通过参与者的政治意识形态、社会支配取向、右翼威权主义、制度正当性和一个特定的道德基础维度：伤害/关怀来解释。另一方面，右翼威权主义、制度正当性、政治意识形态和两个特定的道德基础（忠诚/背叛和权威/颠覆）在预测影响智利马普切原住民的负面事件的历史否定方面发挥着重要作用。我们的结果根据它们对当今马普切人和非土著智利人之间的群体间关系的影响进行了讨论。
