Faux pas. Last week, Science Magazine published a report by John Bohannon on a “sting” that used a faux paper to reveal flaws in the review of manuscripts submitted to open access journals. Not only was the “experiment” flawed (it lacked a proper control), but it was a monumental waste of time for editors & reviewers at legit open access journals. It’s the kind of experiment that would not have passed peer review itself, let alone been approved for ethics. If anything, it uncovered only a flaw in peer review, full stop. Great critiques were made by by Curt Rice, Martin Eve, Kausik Datta, John Hawks and Michael Eisen.
