Multisite (multilab/many-lab) replications have emerged as a popular way of verifying prior research findings, but their record in social psychology has prompted distrust of the field and a sense of crisis. We review all 36 multisite social-psychology replications (plus three articles reporting multiple ministudies). We start by assuming that both the original and the multisite replications were conducted in honest and diligent fashion, despite often yielding different conclusions. Four of the 36 (11%) were clearly successful in terms of providing significant support for the original hypothesis, and five others (14%) had mixed results. The remaining 27 (75%) were failures. Multiple explanations for the generally poor record of replications are considered, including the possibility that the original hypothesis was wrong; operational failure; low engagement of participants; and bias toward failure. The relevant evidence is assessed as well. There was evidence for each of the possibilities listed above, with low engagement emerging as a widespread problem (reflected in high rates of discarded data and weak manipulation checks). The few procedures with actual interpersonal interaction fared much better than others. We discuss implications in relation to manipulation checks, effect sizes, and impact on the field and offer recommendations for improving future multisite projects. [ABSTRACT FROM AUTHOR]

We identify points of conflict and consensus regarding (a) controversial empirical claims and (b) normative preferences for how controversial scholarship—and scholars—should be treated. In 2021, we conducted qualitative interviews (n = 41) to generate a quantitative survey (N = 470) of U.S. psychology professors’ beliefs and values. Professors strongly disagreed on the truth status of 10 candidate taboo conclusions: For each conclusion, some professors reported 100% certainty in its veracity and others 100% certainty in its falsehood. Professors more confident in the truth of the taboo conclusions reported more self-censorship, a pattern that could bias perceived scientific consensus regarding the inaccuracy of controversial conclusions. Almost all professors worried about social sanctions if they were to express their own empirical beliefs. Tenured professors reported as much self-censorship and as much fear of consequences as untenured professors, including fear of getting fired. Most professors opposed suppressing scholarship and punishing peers on the basis of moral concerns about research conclusions and reported contempt for peers who petition to retract papers on moral grounds. Younger, more left-leaning, and female faculty were generally more opposed to controversial scholarship. These results do not resolve empirical or normative disagreements among psychology professors, but they may provide an empirical context for their discussion. [ABSTRACT FROM AUTHOR]
