Leif Nelson making the case for pre-registration:
I recently joined a large group of academics in co-authoring a paper looking at how political science, economics, and psychology are working to increase transparency in scientific publications. Psychology is leading, by the way.
Working on that paper (and the figure below) actually changed my mind about something. A couple of years ago, when Joe, Uri, and I wrote False Positive Psychology, we were not really advocates of preregistration (a la clinicaltrials.gov). We saw it as an implausible superstructure of unspecified regulation. Now I am an advocate. What changed?
