In this episode, Jess and Sara reckon with what the preregistration revolution means in developmental science. We first visited preregistration and registered reports in Season 3. Since then, we’ve been a part of many preregistrations and registered reports, and have reviewed and handled them as editors. Through that process, we’ve noticed that questions often come up about whether something is really a preregistration and whether some studies or analyses can or should be preregistered. 

We mention: 

Several definitions: Open Science Framework:  “Preregistration is the practice of documenting your research plan at the beginning of your study and storing that plan in a read-only public repository”. APA: “Preregistration allows researchers to specify and share the details of their research in a public registry before conducting the study.” IES - no definition, just that you should do it; it’s part of the SEER standards.  REES similarly just says “REES is designed to increase transparency of and access to information about both ongoing and completed efficacy and effectiveness studies.” Even the preregistration revolution article doesn’t include a definition. The closest it gets (about ⅓ of the way through the article is “Preregistration of an analysis plan is committing to analytic steps without advance knowledge of the research outcomes.”
