社会科学研究人员主要是自由派，批评者认为这种代表性可能会因为将自由主义价值观嵌入研究过程而降低研究的稳健性。在一项对抗性合作中，我们研究了心理学研究结果的政治倾向是否与较低的科学可复制性相关。我们分析了 194 篇原始心理学文章，这些文章报告了后来进行复制尝试的研究（N = 1,331,413 名复制参与者），方法是让心理学博士生（研究 1）和来自各个政治领域的美国居民在线样本（研究 2）编码原始研究摘要的政治倾向（自由派与保守派）。方法和分析已预先注册。在这两项研究中，原始研究的自由派或保守派倾向与结果是否成功复制无关。无论编码员的意识形态如何，结果都保持一致。政治倾向与后续引用模式和原始研究的效应大小无关，并且与原始研究的样本量也不一致。然而，我们发现了适度的证据表明，政治倾向较大的研究（无论是自由派还是保守派）的可复制性较差，而统计稳健性始终预示着复制的成功。我们讨论对社会科学、政治和可复制性的影响。
Social science researchers are predominantly liberal, and critics have argued this representation may reduce the robustness of research by embedding liberal values into the research process. In an adversarial collaboration, we examined whether the political slant of research findings in psychology is associated with lower rates of scientific replicability. We analyzed 194 original psychology articles reporting studies that had been subject to a later replication attempt (N = 1,331,413 participants across replications) by having psychology doctoral students (Study 1) and an online sample of U.S. residents (Study 2) from across the political spectrum code the political slant (liberal vs. conservative) of the original research abstracts. The methods and analyses were preregistered. In both studies, the liberal or conservative slant of the original research was not associated with whether the results were successfully replicated. The results remained consistent regardless of the ideology of the coder. Political slant was unrelated to both subsequent citation patterns and the original study’s effect size and not consistently related to the original study’s sample size. However, we found modest evidence that research with greater political slant—whether liberal or conservative—was less replicable, whereas statistical robustness consistently predicted replication success. We discuss the implications for social science, politics, and replicability.
