Wiki Version:
This OSF project hosts our multi-lab replication of the study originally reported by Eskine, Kacinik, and Prinz (2011). We submitted a manuscript for consideration for publication. Following is a draft abstract summarizing this work: Eskine, Kacinik, and Prinz's (2011) influential experiment demonstrated that gustatory disgust triggers a heightened sense of moral wrongness. We report a large-scale multi-site direct replication of this study, conducted by participants in the Collaborative Replications and Education Project (CREP). Participants in each sample were randomly assigned to one of three beverage conditions: bitter/disgusting, control, or sweet. After consuming the assigned beverage, participants made a series of judgments indicating the moral wrongness of the behavior depicted in each of six vignettes. In the original study, drinking the bitter beverage led to higher ratings of moral wrongness than drinking the control and sweet beverages; a beverage contrast (bitter versus both control and sweet) was significant among conservative but not liberal participants. In this report, random effects meta-analyses across all participants (*N* = 1,137 in *k* = 11 studies), conservative participants (*N* = 142, *k* = 5), and liberal participants (*N* = 635, *k* = 9) revealed standardized effect sizes (bitter versus control, bitter versus sweet) that were smaller than reported in the original study. Some were in the opposite of the predicted direction, all had 95% confidence intervals containing zero, and most were smaller than the effect size the original authors could meaningfully detect. In linear mixed-effects regressions, drinking the bitter beverage led to higher ratings of moral wrongness than drinking the control beverage but not the sweet beverage; this pattern was moderated by participants' naivety, but not by political orientation. Participants naive to the hypothesis showed a larger effect for the bitter versus control beverage contrast; the bitter beverage did not lead to higher moral wrongness ratings than the sweet beverage in this group. Bayes Factor tests generally reveal greater relative support for the null than replication hypothesis. In sum, the overall pattern provides only weak support for the theory that physical disgust via taste perception contributes to moral wrongness. We also discuss limitations including low reliability of the moral judgment measure and relatively low numbers of conservative participants across samples.
