The prevalence of direct replication articles in top-ranking psychology journals.

Despite lip service about replication being a cornerstone of science, replications have historically received little real estate in the published literature. Following psychology's recent replication crisis, we assessed the prevalence of one type of replication contribution: direct replication articles-articles where a direct or close replication of a previously published study is one of the main contributions of the article. This prevalence provides one indicator of how much the field values and incentivizes this type of self-correction.
