Does evaluating belief prior to its retraction influence the efficacy of later corrections?

News stories unfold over time, with initial reports sometimes containing mistaken accounts of the newsworthy outcome that are ultimately revised or corrected. Because facts associated with newsworthy events are accumulated in this piecemeal fashion, readers often have repeated opportunities to reflect upon, discuss, and evaluate their belief in these accounts before they learn that initial news reports have been revised or retracted. The primary goal of the present study was to assess whether rating the strength of one's belief in the initially reported, mistaken cause might influence the efficacy of a later correction. In the current study, participants evaluated their belief in the target cause by either rating how much they believed it caused the outcome (Experiment 1) or rating the probability that the target caused the outcome (Experiment 2). The results showed that evaluating belief in a target cause prior to its retraction (relative to not doing so) rendered the correction more effective. This enhanced correction effect was not observed when participants generated the target information prior to its retraction (Experiment 3). Collectively, the results suggest that it is not how much people believe something, but whether they have thought about why they do or do not believe it, that affects their later willingness to revise their mistaken beliefs.
