Editorial commentary
Pre-registration constrains researcher degrees of freedom: any deviation from the pre-registered plan must be flagged as exploratory rather than confirmatory. Registries include OSF Preregistration, AsPredicted, ClinicalTrials.gov (clinical), and the EU Clinical Trials Register. Pre-registration is distinct from registered reports, which include peer review of the plan.
