Registered Report Vs Traditional Article: Key Differences & Comparison | CASRAI
A Registered Report is a two-stage, pre-registered publishing format in which the study is peer-reviewed and accepted before the results exist. A traditional article is reviewed after the work is complete. The difference is designed to curb publication bias and questionable research practices.
Side-by-side comparison
| Dimension | Registered Report | Traditional article |
|---|---|---|
| When peer review happens | Twice — before data collection (Stage 1) and after results (Stage 2) | Once — after the study is complete |
| What is reviewed first | The question, hypotheses, and methods | The whole paper including results and conclusions |
| Acceptance basis | In-principle acceptance on the strength of the design | Acceptance on the strength of the findings |
| Pre-registration | Built in — the protocol is registered and time-stamped | Optional and separate from the journal submission |
| Publication bias | Reduced — null and positive results are published alike | Higher risk — positive results are more likely to be published |
| Guards against | p-hacking, HARKing (hypothesising after results are known), selective reporting | Relies on author integrity and post-hoc review to catch these |
| Flexibility after start | Deviations from the protocol must be declared and justified | Analysis choices can change freely before submission |
| Infrastructure | OSF / Center for Open Science; 300+ journals offer the format | Standard journal submission systems |
| Best suited to | Hypothesis-testing, confirmatory studies | Exploratory, descriptive, or discovery-led work |
Common questions
FAQ
Will my Registered Report be published even if the results are null?+
Yes — that is the central feature. Once a study earns in-principle acceptance at Stage 1, the Stage 2 paper is published regardless of whether the findings support the hypotheses, provided the registered methods were followed and the work was carried out competently.
What problems do Registered Reports address?+
They tackle publication bias (the tendency to publish positive results), p-hacking (analysing data many ways until something is significant), and HARKing (presenting a post-hoc hypothesis as if it were predicted). Reviewing the design before results exist removes the incentive for these practices.
Can I still run exploratory analyses?+
Yes. Registered Reports distinguish pre-registered confirmatory tests from additional exploratory analyses, which can be reported clearly labelled as such. The format constrains the confirmatory claims, not honest exploration.
Where are Registered Reports offered?+
Several hundred journals now offer the format, supported by the Center for Open Science and pre-registration infrastructure such as the OSF. The list spans psychology, neuroscience, medicine, and a growing range of other fields.
