Curtailing the Use of <i>Preregistration</i>: A Misused Term

Improving the usability of psychological research has been encouraged through practices such as prospectively registering research plans. Registering research aligns with the open-science movement, as the registration of research protocols in publicly accessible domains can result in reduced research waste and increased study transparency. In medicine and psychology, two different terms, registration and preregistration, have been used to refer to study registration, but applying inconsistent terminology to represent one concept can complicate both educational outreach and epidemiological investigation. Consistently using one term across disciplines to refer to the concept of study registration may improve the understanding and uptake of this practice, thereby supporting the movement toward improving the reliability and reproducibility of research through study registration. We recommend encouraging use of the original term, registration, given its widespread and long-standing use, including in national registries.
