A couple of times every year, I come across a new effort to improve the research enterprise that excites, inspires, and energizes me. Learning about the OpenTrons robot for biologists was such a moment. Seeing runnable code in publications from CodeOcean was another jaw-dropping experience like it.\n\u00a0\nTwo months ago I was lucky to meet Samantha Hindle and Daniela Saderi who created the non-profit PREreview. I got the same jolt of electricity when I understood what they are doing. PREreview is an open preprint peer review platform that encourages collaborative reviewing of preprints in journal clubs. The reviews are then shared with the preprint authors so that they can use them to to improve the manuscripts before submission to journals.\n\u00a0\nThis is a brilliant effort. Sharing journal club discussions with authors is something that I and many others have talked about for years but couldn't quite nail with our attempts. Samantha and Daniela are going about it in a genius way, coupling the journal clubs to preprints specifically. It is simultaneously disruptive and non-threatening as it benefits everyone.\n\u00a0\nPREreview helps to turn journal clubs from destructive to constructive exercises. Discussing a paper that is already published is too late as the feedback can only irritate or depress the authors because it\u2019s no longer possible to improve the paper. By switching journal club selection to preprints, it suddenly becomes possible to relay constructive feedback that the authors can use to improve their work before it is published.\n\u00a0\nAs PREreview picks up over the next years, the open reviews will also be used by editors and reviewers, reducing the burden on peer reviewers. Think about this - post-publication journal clubs are happening all the time right now, but they are re-reviewing papers. This is a massive redundancy that PREreview will reduce or eliminate.\n\u00a0\nPREreview creates an extra benefit to posting preprints, increases the quality of both preprints and subsequent published papers, and helps to speed up scientific communication. It hurts no one; it helps everyone. Brilliant.\n\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\n\u00a0\nP.S. There have been many attempts over the past years to connect journal club comments to authors. None of them succeeded, for a variety of reasons. However, as I\u2019ve written before, it is important to ask why something failed before and to learn from the mistakes. I have joined the advisory board of PREreview because I am convinced that Daniela and Samantha are the right people to pull this off, are doing it in the exactly right way, and at a time when this will finally work.\n\u00a0\nIf you are a still reading this, please let a few of your colleagues know about PREreview and consider participating yourself, either as a preprint author or a journal club reviewer.
