Edouard Machery's article "What is Replication?" deserves particular critical attention. For if it is correct, his Resampling Account of Replication has the power to reshape the current debate on replication in psychology. Indeed, with his new proposal, philosopher Machery claims to replace the "vague characterization of replication in psychology" (Machery, 2020, p. 559) with an account that deflates one of the central debates on replication-the debate which contraposes direct and conceptual replications and asks which one is preferable. In this commentary, I argue that there are deep-rooted reasons for why the distinction is meaningful, and that the Resampling Account of Replication just offers a misleading "semantic shift."
Public Significance StatementThis commentary argues against the resampling account of replication proposed in Machery (2020) and reflects on the significance of the distinction between direct and conceptual replication, which is common lore in psychology. The discussion offered in this contribution may lead to advances in the understanding of the functions and value of replication in psychology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
