Repeated exposure to misinformation reduces moral condemnation of those falsehoods, as shown by Effron & Raj (2020)1—and moral condemnation may play an important role in stopping the spread of online misinformation. In this registered report, we conceptually replicate previous findings on the effect of repetition and moral condemnation and investigate the generalizability of the findings, using an updated and larger set of false headlines. We also investigate whether asking for accuracy evaluations of the headlines, a type of accuracy prompt that is standard in repeated exposure tasks, alters the effect of repetition on moral condemnation, as inattention to the veracity of headlines may decrease outrage and thus moral condemnation. We find a clear conceptual replication of the negative effect of repetition on moral condemnation, and insufficient evidence for a relationship between accuracy prompts and the effect of repetition.
