The Prevalence of Replication Studies in Human Factors (2020-2024)
DescriptionReplication studies contribute to scientific self-correction and assessing the credibility of a given effect. This study examined the prevalence of replication studies published in Human Factors from 2020 to 2024 (N = 113 coded). Of the studies coded, only five explicitly identified replication as their aim. Of these, one was a direct replication and four were direct replications with extensions; three were conducted by internal teams (i.e., at least one author as in original publication) while two were external (i.e., no authors cross-listed in original publication). These findings suggest that replication studies remain rare in the fields of ergonomics and human factors. In an effort to strengthen research in these fields, it may be worthwhile for journals to incentivize publication of replication studies (e.g., through special issues focused on replication studies).
