People are known to evaluate science based on whether it (dis)affirms their collective identities. We examined whether personal identity concerns also bias evaluation processes by manipulating the degree to which summaries of ostensible scientific research about an unfamiliar topic manipulating whether summaries were or inconsistent with how participants thought about themselves. In three preregistered experiments (N = 644) conducted across two continents, participants were more likely to believe the science when its conclusions aligned with prior understanding of their self, effects that were mediated through positive emotional reactions. Two of the experiments also tested a de-biasing intervention: prior to evaluating science, participants received a brief tutorial on the ecological fallacy (of which, self-related biases represent a special case). The tutorial did not mitigate identity-biased evaluations. This experimental evidence raises questions about whether it is possible to engage global citizens more fully in science consumption while not further triggering identity-based biasing processes.

众所周知，人们会根据科学是否（否定）肯定他们的集体身份来评估科学。我们通过操纵表面上的科学研究摘要在多大程度上操纵摘要是否与参与者对自己的看法不一致或不一致，从而研究了个人身份问题是否也会对评估过程产生偏见。在三个预先注册的实验中（N= 644）在两大洲进行，参与者更有可能相信科学，当它的结论与他们先前对自我的理解一致时，通过积极的情绪反应来调节效果。其中两个实验还测试了消除偏见的干预措施：在评估科学之前，参与者接受了关于生态谬误的简短教程（其中，自我相关的偏见是一个特例）。本教程没有减轻身份偏见评估。这一实验证据提出了一个问题，即是否有可能让全球公民更充分地参与科学消费，同时又不会进一步触发基于身份的偏见过程。
