Abstract

Abstract.

We attempted high-powered direct replications of the two experiments in Schnall, Benton, and Harvey (2008) and did not duplicate the original results. We therefore concluded that more research was needed to establish the size and robustness of the original effects and to evaluate potential moderators. Schnall (2014) suggests that our conclusions were invalid because of potential psychometric artifacts in our data. We present evidence that undermines concerns about artifacts and defend the utility of preregistered replication studies for advancing research in psychological science.
