This project is hosted on the [Many Lab][1]. You can visit the main page for Many Labs 5 [here][2]. **1. What is the project?** Many Labs 5 will test pre-data collection peer review as an intervention improve reproducibility. We will investigate the 11 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 reproducibility rate of peer reviewed protocols to that of non-endorsed protocols. **2. What is required from collaborators?** Collaborators will be expected to contribute to data collection for one or more of the 11 replication projects. Participants must reach a minimum number of participants in *each* of the two replications. Minimum numbers vary by study. We will match collaborators with studies based on their available resources. **3. What will collaborators get out of this?** Each set of replications will be published in its own report. Contributors that meet minimum data collection requirements for a given set will be included as authors on that report. In addition, all authors on all reports will be invited to be an author on a final report that summarizes the results across the various sets of replications. **4. How do I join this project?** To express interest in joining the project, fill out this brief [entry survey][3] by April 21, 2016.
