Nature Lets It All Hang Out Through Open Peer Review

One of the fundamental principles of modern science, as well as other academic pursuits, is peer review. By subjecting a submitted paper to evaluation by other scientists in the authors’ field, the solid science advances at the expense of the not-so-good and the interesting and relevant prevails above the unoriginal. In theory, of course. The effect is a growing body of scientific knowledge that, while still large and unwieldy, is at best authoritative and at the very least trustworthy and accurate. It’s a kind of democratization of knowledge, at least in a narrow sense.

But, as in any democratic system, there are problems. Contrary to the fundamental ideals of a democracy it is inherently exclusive, although this makes sense considering the extensive background knowledge and experience needed to evaluate a scientific manuscript. Of course, individuals also have vested interests in the process as well. Although science strives for objectivity, who reviews your paper does matter, and if you step on the wrong toes by not citing the reviewer’s own “definitive” papers on the subject or, even worse, refute them altogether, your findings might not get the peer review seal of approval.

Even the unimaginable can sometimes happen when results that are completely faked pass right through the peer review process and end up in a top journal. A case of this made headlines recently when a group led by scientist Hwang Woo Suk claimed in two widely-heralded papers published in Science that it had produced various lines of embryonic stem cells from cloned human embryos. In wake of the revelation that the results had been fabricated, a debate on the very nature of peer review ensued.

In that spirit, today's issue of Nature announced its own experiment in science—or democracy—by opening up the peer review process to all interested in participating and giving authors of submitting their papers to an open and public peer review process to take place online:
This publication champions the value of editorially driven or editorially selected content. But we are always keen to try new things, and we are now experimenting around the edges of that principle, to make the most of online interactivity….

…Less certain is the outcome of a trial that we launch this week: a test of a particular type of open peer review. The trial is accompanied by a general online debate about peer review; see http://www.nature.com/nature/peerreview/index.html.

During the trial, which will last several months, Nature's traditional approach to peer review will continue: typically, we send selected submissions to two or three experts whose identities are kept confidential. We believe that this approach works well. Meanwhile, over the next few weeks, the web debate will explore other approaches, as well as the potential for online techniques to unpack the various functions of conventional journals, the ethics of peer review, and more.

Our online trial opens up a parallel track of peer review for submitted papers for authors willing to go down that route. The traditional process will still be applied to all submissions selected for peer review. But we will also offer to post the submitted manuscript onto an open website. Anyone can then respond to it by posting online comments, provided they are willing to sign them. Once Nature's editors have received all the comments from their solicited confidential reviewers, the open website will cease to take comments, and all the opinions will be considered by the editors as well as the authors.

The details of the trial can be found in the online FAQ. Nature published additional articles on the subject here and has made available a forum and a collection of resources on the topic.

So, is this a good idea? It’s hard to say at this point, although Nature seems to be doing the appropriate thing by approaching this experiment cautiously, adding open peer review as an optional preliminary step in the longer peer review process. And, although any peer review process by definition should only include the authors’ peers (i.e. experts in the same or a similar field), this seems to compliment the recent push toward open access literature, which I’ve discussed at length previously.

Although it never comes close enough to the ideal in practice, science should be an open enterprise, characterized by the free exchange of information between professionals dedicated to expanding our body of scientific knowledge. When one takes into consideration the fact that science is largely a taxpayer funded enterprise, a new ideal emerges, one where free open access to the scientific literature and the peer review process allow information to flow uninhibited within the scientific community and enable interested citizens to observe their financial contributions in action.

Putting the grand ideals aside, though, and in light of recent lapses, a few extra pairs of watchful eyes in the process couldn’t hurt.


Update 9 Jun 2006 10:58 GMT: The first article has now been submitted on the Nature site for open peer review. The title of the manuscript is "H5N1 Avian Influenza Virus Evolution: Twice faster than Old Viruses", and it can be found here.
Update 9 Jun 2006 16:44 GMT: ...and another one. It looks like they're on a roll now.

  • I think in principle such a concept as "distributed reviewing" could be very powerful. Certainly analogous methods have succeeded in matters as disparate as the creation of Linux to debunking the forgeries of GWB's National Guard records, but I'm skeptical that it will work here in the end. Professional scientists barely have time to complete the refereeing that they are already asked to do, much less volunteering for more. I think that after the novelty of the new Nature system wears off, they will be hard pressed to get much commentary.

    Perhaps I am wrong though. I hope I'm wrong. Perhaps the opportunity to sign ones name and get some credit for clever insight and hard work will give the incentive to experts to make the system work. Perhaps we'll spend time commenting on preprints instead of leaving comments on blogs.

    Otherwise, what to do? I dunno. The analogy of peer review and democracy is very apt. As Winston Churchill might have said if he was the Nature editor, "Our current system of peer review is the worst form possible in the entire world...except for all the rest."
