    Abstract

    Lee and Schwarz interpret meta-analytic research and replication studies as providing evidence for the robustness of cleansing effects. We argue that the currently available evidence is unconvincing because (a) publication bias and the opportunistic use of researcher degrees of freedom appear to have inflated meta-Analytic effect size estimates, and (b) preregistered replications failed to find any evidence of cleansing effects.
