a.k.a. Love v Kriegeskorten
An interesting little spat played out on science social media today. It began with a blog post by Niko Kriegeskorte, in which he posted a peer review he had conducted on a manuscript by Brad Love. The manuscript in question is publicly available as a preprint. I don’t want to go into too much detail here (you can read that all up for yourself) but Brad took issue with the fact and the manner in which Niko posted the review of their manuscript after it was rejected by a journal. A lot of related discussion also took place via Twitter (see links in Brad’s post) and on Facebook.
I must say, in the days of hyper-polarisation in everyday political and social discourse, I find this debate actually really refreshing. It is actually pretty easy to feel outrage and disagreement with a president putting children in cages or holding a whole bloody country hostage over a temper tantrum – although the fact that there are apparently still far too many people who do not feel outraged about these things is certainly a pretty damning indictment of the moral bankruptcy of the human race… Anyway, things are actually far more philosophically challenging when there is a genuine and somewhat acrimonious disagreement between two sides you respect equally. For the record, Brad is a former colleague of mine from my London days, whose work I have the utmost respect for. Niko has for years been a key player in multivariate and representational analysis and we have collaborated in the past.
Whatever my personal relationship to these people, I can certainly see both points of view in this argument. Brad seems to object mostly to the fact that Niko posted the reviews on this blog and without their consent. He regards this as a “self-serving” act. In contrast, Niko regards this as a substantial part of open review. His justification for posting this review publicly is that the manuscript is already public anyway, and that this invites public commentary. I don’t think that Brad particularly objects to public commentary, but he sees a conflict of interest in using a personal blog as a venue for this, especially since these were the peer reviews Niko wrote for a journal, not on the preprint server. Moreover, since these were reviews that led to the paper being rejected by the journal, he and his coauthors had no opportunity to reply to Niko’s reviews.
This is a tough nut to crack. But this is precisely the kind of discussion we need to have for making scientific publishing and peer review more transparent. For several years now I have argued that peer reviews should be public (even if the reviewers’ names are redacted). I believe reviewers’ comments and editorial decisions should be transparent. I’ve heard “How did this get accepted for publication?” in journal clubs just too many times. Show the world why! Not only is it generally more open but it will also make it fairer when there are challenges to the validity of an editorial decision, including dodgy decisions to retract studies.
That said, Brad certainly has a point that ethically this openness requires up-front consent from both parties. The way he sees it, he and his coauthors did not consent to publishing these journal reviews (which, in the present system, are still behind closed doors). Niko’s view is clearly that because the preprint is public, consent is implicit and this is fair game. Brad’s counterargument to this is that any comments on the preprint should be made directly on the preprint. This is separate from any journal review process and would allow the authors to consider the comments and decide if and how to respond to them. So, who is right here?
What this really comes down to is a philosophical worldview as to how openness should work and how open it should be. In a liberal society, the right to free expression certainly permits a person to post their opinions online, within certain constraints to protect people from libel, defamation, or threats to their safety. Some journals make reviewers sign a confidentiality agreement about reviews. If this was the case here, a post like this would constitute a violation of that agreement, although I am unaware of any case where this has ever been enforced. Besides, even if reviewers couldn’t publicly post their reviews and discuss the peer review of a manuscript, this would certainly not stop them from making similar comments at conferences, seminars – or on public preprints. In that regard, in my judgement Niko hasn’t done anything wrong here.
At the same time, I fully understand Brad’s frustration. I personally disagree with the somewhat vitriolic and accusatory tone of his response to Niko. This seems both unnecessary and unhelpful. But I agree with him that a personal blog is the wrong venue for posting peer reviews, regardless of whether they are from behind the closed doors of a journal review process or from the outside lawn of post-publication discussion. Obviously, nobody can stop anyone from blogging their opinion on a public piece of science (and a preprint is a public piece of science). Both science bloggers and mainstream journalists constantly write about published research, including preprints that haven’t been peer reviewed. Twitter is frequently ablaze with heated discussion about published research. And I must say that when I first skimmed Niko’s post, I didn’t actually realise that this was a peer review, let along one he had submitted to a journal, but simply thought it was his musings about the preprint.
The way I see it, social media aren’t peer review but mere opinion chatter. Peer review requires some established process. Probably this should have some editorial moderation – but even without that, at the very least there should be a constant platform for the actual review. Had Niko posted his review as a comment on the preprint server, this would have been entirely acceptable. In an ideal world, he would have done that after writing it instead of waiting for the journal to formally reject the manuscript*. This isn’t to say that opinion chatter is wrong. We do it all the time and talking about a preprint on Twitter is not so different from discussing a presentation you saw at a conference or seminar. But if we treat any channel as equivalent for public peer review, we end up with a mess. I don’t want to constantly track down opinions, some of which are vastly ill-informed, all over the wild west of the internet.
In the end, this whole debacle just confirms my already firmly held belief (Did you expect anything else? 😉 ) that the peer review process should be independent from journals altogether. What we call preprints today should really be the platform where peer review happens. There should be an editor/moderator to ensure a decent and fair process and facilitate a final decision (because the concept of eternally updating studies is unrealistic and infeasible). However, all of this should happen in public. Importantly, journals only come into play at the end, to promote research they consider interesting and perhaps some nice editing and formatting.
The way I see it, this is the only way. Science should happen out in the open – including the review process. But what we have here is a clash between promoting openness in a world still partly dominated by the traditional way things have always been done. I think Niko’s heart was in the right place here but by posting his journal reviews on his personal blog he effectively went rogue, or took the law into his own hands, if you will. Perhaps this is the way the world changes but I don’t think this is a good approach. How about we all get together and remake the laws. They are for us scientists after all, to determine how science should work. It’s about time we start governing ourselves.
