Preregistration is the act of submitting a study plan, ideally also with analytical plan, to a registry prior to conducting the work. Preregistration increases the discoverability of research even if it does not get published further. Adding specific analysis plans can clarify the distinction between planned, confirmatory tests and unplanned, exploratory research.
A (pre)registration form specification
This preprint contains a template for the "OSF Prereg" form available from the OSF Registry. An earlier version was originally developed for the Preregistration Challenge, an education campaign designed to initiate preregistration as a habit prior to data collection in basic research, funded by the Laura and John Arnold Foundation (now Arnold Ventures) and conducted by the Center for Open Science. More information is available at https://www.cos.io/initiatives/prereg/, and other templates are available at: https://osf.io/zab38/"
