When a scientist submits a paper for publication to a journal, he entrusts the journal editor with the task of finding peers would be able to review the paper and are knowledgeable enough to assess its scientific merit. The names of the reviewers are typically concealed to the author. The intent is to grant the reviewer complete freedom in his candid assessment without fear of retaliation. The system is imperfect, very much so, but during the last three centuries scientists have not managed to come up with anything better.
Post-publication peer review (PPPR), on the other hand, cannot be said to be imperfect. It is not even wrong. It is a grotesque aberration. PPPR is usually anonymous but in this case we have absolutely no assurance that the reviewer of the paper is a peer of the author, that is, someone capable of passing serious judgment, or rather someone with an ax to grind launching his or her personal attack. There is simply no editor that arbitrates PPPR, just reporters or science outsiders, like Ivan Oransky, who typically know nothing of the scientific subject of the paper and who merely reproduce a note in a journal or a piece of gossip or an opinion without adding any value. The consequences of this lack of leadership are dire for science: about 90% of the attacks launched by Oransky’s blog Retraction Watch under the pseudonym Clare Francis are either false or lacking merit, even if they manage to elicit an “expression of concern” (an illegality stigmatizing a person presumed innocent unless proven guilty). If US president Donald Trump branded reporters as a pathetic dishonest bunch, just imagine what he would have to say about blogs like Retraction Watch, where the founding reporters usually know nothing about the science related to their mini-scandals.
This atmosphere of dishonesty provides a fertile soil for PPPR, where a few snipers like Joshua L. Cherry (NIH/NCBI?) strive. As readers may recall, Joshua L. Cherry has been identified by Science Transparency. Cherry is truly obsessed (read Cherry’s exchange with Prof. John Ioannidis), but unfortunately not with producing good science. When he launches personal attacks, Cherry disguises under multiple pseudonyms and e-mails, he cowardly shoots from the shadows, yet his style remains unmistakable: He obsessively insists in performing statistical analysis of large datasets with no scientific understanding of the data, or obsessively tries to reproduce data in a field he knows nothing about, failing miserably. Unfortunately, Joshua L. Cherry is the kind of byproduct that Retraction Watch and other such blogs generate. Were it not for the lack of leadership in PPPR, Cherry would have probably remained a scientist perhaps not incapable of generating interesting ideas. Yet, like many at Retraction Watch, he got trapped in futile battles against windmills.
As the Romans used to say: video meliora proboque, deteriora sequor ( I see the best and verify it, but I follow the worst). Tragic, tragic…
