Depositing your study design in a repository is a way of holding yourself to the highest standards of research integrity, while at the same time ensuring that your work will be reproducible in the future. Submitting your study design to a journal brings two additional benefits: expert peer review feedback to ensure the best possible methodological and analytical approach, and an editorial decision based solely on the quality of the research and the important of the research question–not the results.
At PLOS, we see preregistration as an important step towards a more open and transparent peer review process – one that brings with it tremendous benefits for both individual authors and the broader scientific community.
