Neuroscience journal changes policy on last-minute add-ins
John Maunsell, editor-in-chief of The Journal of Neuroscience advises that his publication is ending the practice of permittting the submission of publication of additions to submitted materials online. He explains,
We recognize that this is a major change that will set The Journal apart from most neuroscience journals, but the Society for Neuroscience Council has approved this step because supplemental material has begun to undermine the peer review process in important ways. We believe that the changes described here are our best option for protecting peer review and maintaining our leadership in publishing articles of the greatest significance and highest quality. Because not all of the problems associated with supplemental material will be obvious to readers, we explain them here.It probably also functions as a way to front nonsense, but Maunsell would be too polite to say so.

Although The Journal, like most journals, currently peer reviews supplemental material, the depth of that review is questionable. Most well qualified reviewers are overburdened with requests to review manuscripts, and many feel that it is too much to ask them to also evaluate supplemental material that can be as extensive as the article itself. It is obvious to editors that most reviewers put far less effort (often no effort) into examining supplemental material. Nevertheless, we certify the supplemental material as having passed peer review.
Another troubling problem associated with supplemental material is that it encourages excessive demands from reviewers. Increasingly, reviewers insist that authors add further analyses or experiments "in the supplemental material." These additions are invariably subordinate or tangential, but they represent real work for authors and they delay publication. Such requests can be an unjustified burden on authors. In principle, editors can overrule these requests, but this represents additional work for the editors, who may fail to adequately referee this aspect of the review.
Reviewer demands in turn have encouraged authors to respond in a supplemental material arms race. Many authors feel that reviewers have become so demanding they cannot afford to pass up the opportunity to insert any supplemental material that might help immunize them against reviewers' concerns.
Supplemental material also undermines the concept of a self-contained research report by providing a place for critical material to get lost.
