The psychological literature on prejudice and conspiracy theory belief have generally remained distinct, implicitly treating the two as unrelated phenomena. In this brief review, I demonstrate that the two phenomena share at least three dispositional precursors: ingroup bias, right-wing ideology (specifically right-wing authoritarianism and social dominance orientation), and need for closure. The evidence I present suggests that prejudice and conspiracy beliefs may be more closely related both conceptually and normatively than existing research has indicated. In particular, they may appear in the same individuals, cause similar kinds of harms in adherents as well as target populations, and respond to similar counteractive interventions.

偏见和阴谋论信仰的共同心理根源

关于偏见和阴谋论信仰的心理学文献总体上仍然是截然不同的，隐含地将两者视为不相关的现象。在这篇简短的回顾中，我证明这两种现象至少有三个共同的倾向：内群体偏见、右翼意识形态（特别是右翼威权主义和社会统治取向）以及封闭的需要。我提供的证据表明，偏见和阴谋论在概念上和规范上的相关性可能比现有研究表明的更为密切。特别是，它们可能出现在同一个人身上，对追随者和目标人群造成类似的伤害，并对类似的反作用干预措施做出反应。
