Love and Power: Grau and Pury (2014) as a Case Study in the Challenges of X-Phi Replication

Grau and Pury ( Review of Philosophy and Psychology, 5 , 155–168, 2014 ) reported that people’s views about love are related to their views about reference. This surprising effect was however not replicated in Cova et al.’s ( in press ) replication study. In this article, we show that the replication failure is probably due to the replication’s low power and that a metaanalytic reanalysis of the result in Cova et al. suggests that the effect reported in Grau and Pury is real. We then report a large, highly powered replication that successfully replicates Grau and Pury 2014 . This successful replication is a case study in the challenges involved in replicating scientific work, and our article contributes to the discussion of these challenges.
