人们不断受到信息的轰炸，他们可以利用这些信息来调整自己的信念。在这里，我们感兴趣的是探索社会规范对信念更新的影响。为了进行调查，我们招募了200名普林斯顿大学的学生作为样本，他们首先对一组陈述的准确性进行了评级（预测试）。然后，他们被提供了支持或反对最初陈述的相关证据，并被要求对每条证据的说服力进行评分。这些证据被随机分配为规范或非规范，也被随机分配为轶事或科学。最后，参与者再次对最初的一组陈述的准确性进行打分（测试后）。结果显示，当证据是科学的，而不是轶事的时候，参与者更容易根据证据改变自己的信念。更重要的是，对于我们的初步调查，结果表明，当证据被描述为规范时，与证据被描述为非规范时相比，参与者更容易根据证据改变他们的信念，这表明社会规范对信念有重大影响。这两种效应都是由参与者对证据可信度的主观评价所介导的，这表明了证据被选择性地纳入信念系统的机制。
People are constantly bombarded with information they could use to adjust their beliefs. Here, we are interested in exploring the impact of social norms on belief update. To investigate, we recruited a sample of 200 Princeton University students, who first rated the accuracy of a set of statements (pre-test). They were then provided with relevant evidence either in favor or against the initial statements, and they were asked to rate how convincing each piece of evidence was. The evidence was randomly assigned to appear as normative or non-normative, and also randomly assigned to appear as anecdotal or scientific. Finally, participants rated the accuracy of the initial set of statements again (post-test). The results show that participants changed their beliefs more in line with the evidence, when the evidence was scientific compared to when it was anecdotal. More importantly to our primary inquiry, the results show that participants changed their beliefs more in line with the evidence when the evidence was portrayed as normative compared to when the evidence was portrayed as non-normative, pointing to the impactful influence social norms have on beliefs. Both effects were mediated by participants’ subjective evaluation of the convincingness of the evidence, indicating the mechanism by which evidence is selectively incorporated into belief systems.
