Selectively integrating new information contributes to belief polarization and compromises public discourse. To better understand factors that underlie biased belief updating, I conducted three pre-registered studies covering different controversial political issues. The main hypothesis was that cognitively devaluing new information hinders belief updating. Support for this hypothesis was found in only one of the three issues. The only factor that consistently influenced belief updating across issues was the discrepancy between prior beliefs and new information. These results suggest that usually people do use evidence to correct their beliefs, but may refuse to do so if doubts about its generalizability arise.
选择性地整合新信息会导致信仰极化，并损害公共话语。为了更好地理解导致有偏见的信仰更新的因素，我进行了三项预先注册的研究，涵盖了不同的有争议的政治问题。主要假设是，认知贬低新信息会阻碍信仰更新。这个假设只在三个问题中的一个得到了支持。唯一在所有问题中都一致影响信仰更新的因素是先验信念和新信息之间的差异。这些结果表明，通常人们确实会使用证据来纠正自己的信念，但如果对证据的普遍性产生怀疑，他们可能会拒绝这样做。
