Classic studies of pouting are helping psychologists explore replication.

Recent discussions about reproducibility within the psychology community have been heated and, at times, acrimonious. The registered replication report by Wagenmakers et al. and the comment by Strack map out one way forward, in terms of experimental design, analysis, interpretation, and rebuttal. The original study, a classic from 1988, reported the effect of facial expressions (a smile or a pout) on a subsequent affective judgment. The replication involved 17 laboratories following a vetted experimental design and blinded analysis plan. The overall result is nonreplication, although Strack offers reasons why the original effect was not observed.
