Beliefs have long been theorized to predict behaviors and thus have been the target of many interventions aimed at changing false beliefs in the population. But does changing beliefs translate into predictable changes in behaviors? Here, we investigated the impact of belief change on behavioral change across two experiments (N = 576). Participants rated the accuracy of a set of health-related statements and chose corresponding campaigns to which they could donate funds in an incentivized-choice task. They were then provided with relevant evidence in favor of the correct statements and against the incorrect statements. Finally, they rated the accuracy of the initial set of statements again and were given a chance to change their donation choices. We found that evidence changed beliefs and this, in turn, led to behavioral change. In a preregistered follow-up experiment, we replicated these findings with politically charged topics and found a partisan asymmetry in the effect, such that belief change triggered behavioral change only for Democrats on Democratic topics, but not for Democrats on Republican topics or for Republicans on either topic. We discuss the implications of this work in the context of interventions aimed at stimulating climate action or preventative health behaviors.

政治和非政治信仰的改变会引发行为的改变。

长期以来，信仰一直被理论化为预测行为，因此成为许多旨在改变人们错误信仰的干预措施的目标。但信念的改变是否会转化为可预测的行为变化？在这里，我们通过两个实验研究了信念改变对行为改变的影响 (N = 576)。参与者评估了一组与健康相关的陈述的准确性，并选择了他们可以在激励选择任务中捐赠资金的相应活动。然后向他们提供了支持正确陈述和反对错误陈述的相关证据。最后，他们再次评估最初一组陈述的准确性，并有机会改变他们的捐赠选择。我们发现证据改变了信念，而这反过来又导致了行为的改变。在一项预先注册的后续实验中，我们用政治性话题复制了这些发现，并发现其效果存在党派不对称性，因此信仰改变只会引发民主党人在民主党话题上的行为改变，但不会引发民主党人在共和党话题上的行为改变，也不会导致共和党人在政治话题上的行为改变。任一主题。我们在旨在刺激气候行动或预防性健康行为的干预措施的背景下讨论这项工作的影响。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
