<p><strong>Original citation:</strong> Schnall S., Benton J., & Harvey S. (2008). With a clean conscience: Cleanliness reduces the severity of moral judgments. <i>Psychological Science</i>, 19, 1219-1222.</p> <p><strong>Target of replication:</strong> We attempted to replicate the finding that participants primed with cleanliness would make less severe moral judgments than participants given a neutral prime (Exp. 1). We also attempted to replicate the finding that participants who washed their hands after experiencing disgust would make less severe moral judgments than participants who did not wash their hands (Exp. 2).</p> <p><strong>A priori replication criteria:</strong> A successful replication would find that participants primed with cleanliness (Exp. 1) or participants who washed their hands (Exp. 2) made less severe judgments, as defined by lower scores on a composite measure of all six moral scenarios when tested with a single factor ANOVA.</p> <p><strong>Materials, Data, and Report Study materials</strong> for studies can be found in the "Study 1 Materials" and "Study 2 Materials" components of this project. The raw data, codebook, and syntax can be found in the "Study 1 Dataset" and "Study 2 Dataset" components. The full report and other ancillary analyses appear in the files section of this node.</p> <p><strong>Conclusions.</strong> We did not replicate the key finding of Experiment 1: participants primed with cleanliness did not make less severe moral judgments on the moral composite than those given a neutral prime, <i>F</i>(1, 206) = 0.004, <i>p</i> = .95, <i>d</i> = -0.01. We also did not replicate the key finding of Experiment 2: participants who washed their hands after experiencing disgust did not make less severe moral judgments on the moral composite than those who did not wash their hands, <i>F</i>(1, 124) = 0.001, <i>p</i> = .97, <i>d</i> = 0.005.</p> <p>In the full report we discuss the possibility of hidden moderators that might explain the discrepancy between the results in this replication and those from the original study. We also examine our results using the criteria proposed by Simonshon (2013) for evaluating replications. The relevant files for those analyses are also available in the files section.</p>
