Has this study been replicated?
The atlas records 7 replications of this study. Recorded outcomes: 3 failed, 3 successful, 1 mixed.
Replications
- Does Cleanliness Influence Moral Judgments?, Johnson et al. (2014). Outcome recorded: failed.
We did not find evidence that physical cleanliness reduced the severity of moral judgments using samples sizes that provided over .99 power to detect the original effect sizes.
View paper - Eleven years of student replication projects provide evidence on the correlates of replicability in psychology, Boyce et al. (2023). Outcome recorded: failed.
Subjective replication success rating = 0 (failed). The replication report rated each sub-outcome on a 0-1 scale; the row is recorded as failed only when all sub-outcomes equal 0, successful only when all equal 1, and mixed for any value strictly between.
View paper - Does cleanliness influence moral judgments? Response effort moderates the effect of cleanliness priming on moral judgments, Huang (2014). Outcome recorded: successful.
An online replication (Study 1, N = 214) provided evidence that, when participants exerted low (yet still acceptable) levels of response effort to the experimental material, cleanliness priming led to more lenient moral judgments than neutral priming.
View paper - Influence of Cleanliness on Moral Judgements: A Direct Replication of Schnall, Benton, and Harvey (2008), Chaves et al. (2018). Outcome recorded: uninformative.
Inconclusive because our results are neither significantly different from the null nor the original.
View paper - Replication of "With a clean conscience: Cleanliness reduces the severity of moral judgments" by Schnall, Benton, and Harvey (2008, Psychological Science), Lee (2013). Outcome recorded: failed.
The confirmatory analyses of the current study failed to replicate the findings from the original article.
- Cleanliness primes less severe moral judgments, Besman et al. (2013). Outcome recorded: successful.
This result is consistent with the results of the original study.
- Clean thoughts lead to less severe moral judgment, Arbesfeld et al. (2014). Outcome recorded: successful.
Outcome classified as "Successful Replication" (the project's own label).
