Preregistration is the practice of registering the hypotheses, methods, or analyses of a scientific study before it is conducted.[1][2] Clinical trial registration is similar, although it may not require the registration of a study's analysis protocol. Finally, registered reports include the peer review and in principle acceptance of a study protocol prior to data collection.[3]
Preregistration has the goal to allow others to transparently evaluate the capacity of a test to falsify a prediction.[4] A number of research practices such as p-hacking, publication bias, data dredging, inappropriate forms of post hoc analysis, and HARKing increase the probability of incorrect claims. Although the idea is old,[5] the practice of preregistering studies has gained prominence to mitigate to some of the issues that are thought to underlie the replication crisis.[1]
