How Accurate Are Accuracy-Nudge Interventions? A Preregistered Direct Replication of Pennycook et al. (2020)
复制了Pennycook等人(2020)的发现，即要求人们思考一条新闻标题的准确性是否能提高其对COVID-19新闻分享意图的“真相辨别能力”，结果发现效果微弱且仅在合并数据后显著。
As part of the Systematizing Confidence in Open Research and Evidence (SCORE) program, the present study consisted of a two-stage replication test of a central finding by Pennycook et al. (2020), namely that asking people to think about the accuracy of a single headline improves “truth discernment” of intentions to share news headlines about COVID-19. The first stage of the replication test ( n = 701) was unsuccessful ( p = .67). After collecting a second round of data (additional n = 882, pooled N = 1,583), we found a small but significant interaction between treatment condition and truth discernment (uncorrected p = .017; treatment: d = 0.14, control: d = 0.10). As in the target study, perceived headline accuracy correlated with treatment impact, so that treatment-group participants were less willing to share headlines that were perceived as less accurate. We discuss potential explanations for these findings and an unreported change in the hypothesis (but not the analysis plan) from the preregistration in the original study.
