A large proportion of the authors are members of FORRT, an organization dedicated to integrating open and reproducible science into higher education. LR, LW, FA, and JG are inaugural editors of the in-development journal Replication Research (https://replicationresearch.org). Besides their conviction of the value of replications, their current project’s success relies on researchers conducting reproductions and replications. LR is the managing director of an institutional open science center and proponent of repetitive research. The authors declare that they have no further potential conflicts of interest.
