Description: Many Labs 5 will test pre-data collection peer review as an intervention improve replicability. We will investigate 10 replications from the Reproducibility Project: Psychology that were labeled as “not endorsed.” For each study, we will conduct two replications multiple times each: 1) a direct replication using the non-endorsed protocol from RP:P and 2) a replication using an improved protocol that was vetted through peer review. We will compare the replicability rate of peer reviewed protocols to that of non-endorsed protocols. See the Wiki, below, for the project proposal.
