Cleanliness priming effect
Collection type: Single effect Multi-method Multi-lab Replications 7
Collection contains 7 replications of the cleanliness priming effect across 2 methods.
Summary : The main finding that cleanliness priming reduces the severity of moral judgments currently exhibits replication difficulties (overall meta-analytic effect: r = -.08 [+/-.13]). In a follow-up commentary, Schnall argued that a ceiling effect in Johnson et al.'s (2014a) studies render their results uninterpretable and hence their replication results should be dismissed. However, independent re-analyses by Simonsohn, Yarkoni, Schönbrodt, Inbar, Fraley, and Simkovic appear to rule out such ceiling effect explanation, hence, Johnson et al.'s (2014a) results should be retained in gauging the replicability of the original cleanliness priming effect. Of course, it's possible "cleanliness priming" may be replicable under different operationalizations, conditions, and/or experimental designs (e.g., within-subjects).
