Social psychology and related disciplines are seeing a resurgence of interest in replication, as well as actual replication efforts. But prior work suggests that even a clear demonstration that a finding is invalid often fails to shake acceptance of the finding. This threatens the full impact of these replication efforts. Here we show that the actions of two key players--journal editors and the authors of original (invalidated) research findings--are critical to the broader public's continued belief in an invalidated research conclusion. Across three experiments, we show that belief in an invalidated finding falls sharply when a critical failed replication is published in the same--versus different--journal as the original finding, and when the authors of the original finding acknowledge that the new findings invalidate their conclusions. We conclude by discussing policy implications of our key findings.
社会心理学和相关学科对复制的兴趣以及实际的复制工作正在重新兴起。但是先前的工作表明,即使清楚地表明一个发现是无效的,也往往无法阻止人们接受这个发现。这威胁到这些复制工作的全部影响。在这里,我们表明,两个关键角色——期刊编辑和原始(无效)研究结果的作者——的行为对于更广泛的公众继续相信一个无效的研究结论至关重要。在三个实验中,我们表明,当一个关键的失败复制在与原始发现相同(而不是不同)的期刊上发表时,以及当原始发现的作者承认新发现使他们的结论无效时,对一个无效发现的信念会急剧下降。最后,我们讨论了我们关键发现的政策含义。
