The spread of misinformation threatens democratic societies, hampering informed decision-making. Partisan identity biases perceptions of reality, promoting false beliefs. The Identity-based Model of Political Belief explains how social identity shapes information processing and contributes to misinformation. According to this model, social identity goals can override accuracy goals, leading to belief alignment with party members rather than facts. We propose an extended version of this model that incorporates the role of informational context in misinformation belief and sharing. Partisanship involves cognitive and motivational aspects that shape party members' beliefs and actions. This includes whether they seek further evidence, where they seek that evidence, and which sources they trust. Understanding the interplay between social identity and accuracy is crucial in addressing misinformation.

更新基于身份的信仰模型：从错误信仰到错误信息的传播

错误信息的传播威胁着民主社会，阻碍了明智的决策。党派身份使人们对现实的看法产生偏见，助长错误的信念。基于身份的政治信仰模型解释了社会身份如何影响信息处理并导致错误信息。根据这个模型，社会认同目标可以凌驾于准确性目标之上，导致信念与党员而不是事实保持一致。我们提出了该模型的扩展版本，其中包含了信息背景在错误信息信念和共享中的作用。党派关系涉及塑造党员信念和行动的认知和动机方面。这包括他们是否寻求进一步的证据、他们在哪里寻求证据以及他们信任哪些来源。了解社会身份和准确性之间的相互作用对于解决错误信息至关重要。
