When Replication Fails: What to Conclude and Not to Conclude?

Abstract

In this commentary, we examine the implications of the failed replication reported by Vaidis et al., which represents the largest multilab attempt to replicate the induced-compliance paradigm in cognitive-dissonance theory. We respond to commentaries on this study and discuss potential explanations for the null findings, including issues with the perceived choice manipulation and various post hoc explanations. Our commentary includes an assessment of the broader landscape of cognitive-dissonance research, revealing pervasive methodological limitations, such as underpowered studies and a lack of open-science practices. We conclude that our replication study and our examination of the literature raise substantial concerns about the reliability of the induced-compliance paradigm and highlight the need for more rigorous research practices in the field of cognitive dissonance.
