The Accountable Replication Policy commits the Psychology and Cognitive Neuroscience section of Royal Society Open Science to publishing replications of studies previously published within the journal. Authors can either submit a replication study that is already completed or a proposal to replicate a previous study. To ensure that the review process is unbiased by the results, submissions will be reviewed with existing results initially redacted (where applicable), or in the case of study proposals, before the results exist. Submissions that report close, clear and valid replications of the original methodology will be offered in principle acceptance, which virtually guarantees publication of the replication regardless of the study outcome.
