Registered Reports

Registered Reports move substantive peer review to an earlier point, before the relevant results are known. A qualifying format offers in-principle acceptance based on the question and proposed methods, subject to stated conditions.

Would the planned study produce informative evidence regardless of whether its results support the researchers’ preferred hypothesis?

How it works

  1. Choose an outlet and read its specific rules. Prepare the first-stage rationale, design, analysis plan, and outcome-neutral quality checks. Resolve methodological concerns while there is still an opportunity to improve the study before the relevant evidence is collected.
  2. Obtain in-principle acceptance and meet the applicable ethics requirements before carrying out the agreed study. Preserve a clear record of the approved plan and discuss necessary changes with the editors rather than silently replacing the registered method.
  3. Write the second-stage report with results, interpretation, and a transparent account of adherence and deviations. Acceptance remains conditional on matters such as quality assurance and reporting; it should not depend on whether the primary result is exciting or statistically significant.

A null result that still answers a question

Teaching scenario

Synthetic teaching scenario: A team proposes comparing two ways of presenting study reminders. Reviewers identify an ambiguous primary outcome before the study begins and ask for a clearer measure of completed practice sessions. After the protocol receives in-principle acceptance, the team follows it and estimates a small, uncertain difference. Students discuss how that result would be reported under the agreed design, what the uncertainty allows them to conclude, and why an inconclusive estimate is different from demonstrating that the reminder formats are identical.

This example is constructed for learning. It does not report an observed research result.

What can you conclude?

It creates a publication decision that is less dependent on the attractiveness of the eventual outcome and permits early methodological feedback.

Limits and common mistakes

  • In-principle acceptance is conditional; serious failures of agreed quality checks or reporting can still prevent final publication.
  • An ordinary preregistration is not a Registered Report, and journals differ in eligibility, stages, and implementation details.

A mistake to catch

Assuming that a registry submission supplies peer review or that in-principle acceptance guarantees publication regardless of execution.
