A Science and Policy item by Jocelyn Kaiser covers the recent proposals on changing grant review criteria from CSR. In her framing “Researchers familiar with the National Institutes of Health’s (NIH’s) peer-review process can cite many cases where the reputation of a scientist or their workplace seemed to count for more than the strength of their ideas.“. Distressingly anecdotal, but sure, many scientists do assert this now and again. I have certainly had experiences in grant review panels that would be consistent with the notion that a Big Deal PI can often get a great score with a proposal that one predicts would do much more poorly with a lesser-known PI at the helm. Kaiser quotes Noni Byrnes, Director of the CSR, as follows:
“Anyone who actually attends a study section sees [reputational bias] happening,” says Noni Byrnes, director of NIH’s Center for Scientific Review (CSR), referring to NIH peer-review panels. Now, in a bid to reduce that bias, her center is proposing the first overhaul of NIH’s scoring system in 14 years. But the idea is getting a mixed reception.
I had previously discussed my skepticism that merely instructing reviewers not to focus on the applicant institution and PI reputations was going to produce any functional change. Some wag on Twitter (I’ve since lost track of the tweet) observed that it is odd that someone who has been employed at CSR for over two decades is only now getting around to doing anything about this reputational bias problem. She started as a SRO so presumably she “actually attend(ed)” many a meeting.
As per my usual, this has me returning to the structure of NIH grant review panels and the inherent grinding circular conservatism of recruiting reviewers from the ranks of the already-successful. That is a pretty entrenched rule. A related concern is the idea that SRO’s select reviewers as a limited subset of those who are submitting grants. It is much harder to assess, but this is another place where reputational biases related to the person’s institution or the person’s connections in the field may accelerate the inherent conservatism. Today I am off in the little corner of the Conflict of Interest rules that may be relevant. Not the institutional employment ones, but the ones having to do with a significant mentor/mentee relationship. For NIH grant review, this is codified as having co-published within the past three years or has had other professional relationships (“served as mentor” is the only example given) in the past three years.
Training pedigrees play into both the kind of bias for topics that was identified in Hoppe et alia (2019) as well as the reputational bias of present concern to Director Byrnes. There is just no denying that a given research active scientist get direct career benefit from the successes of their academic progeny. Amazing scientists who publish great papers, get grants, train additional scientists…these are of specific credit to their mentors. They are the evidence used in mentoring awards. They are writing papers that cite the mentor’s work. They are doing the science in the same general area or using the same general techniques, thereby persuading everyone that this is hott stuffe. Mentees generate that sense of importance for the mentor’s research that then influences said mentor’s grant review outcomes. These benefits of the success of a mentee do not magically end after three years. If anything, the benefits are weakest in the first three years since the mentee is just getting their operation up and running.
It is in the career-long interest of a mentor to give good scores to the proposals of their once-mentees.
And vice versa, once that mentee has established themselves. And it just keeps going on into the next generation. The success of academic grandchildren also benefit the career success of the academic grandparent.
Interestingly, Twitter is not seeing it quite this way today. Now I asked the question as generically about peer review as I could.
I was heartened to see that at least on the time limitation, there was some agreement that the COI basically never ends. But when I asked about extending this to subsequent generations…
…the audience balked.
I think because it is easy to think of bias as a very specific and individual thing. A matter of personal relationships. Merit being overmatched by a presumed close personal feeling of wanting that person to do well. It is much harder to think about these longer arcs of professional benefit. It seems entirely defensible for individual reviewers to advocate strongly for funding science in their own areas of interest or using techniques, models or approaches that they just so happen to also use. If that happens to be a trainee from >3 years past, well, that’s just the science talking, right?
And yet this is very intimately related to the problem of “reputational bias” that Byrnes is trying to diminish.
Does it help to translate this to academic hiring? A very specific and individual benefit to the prospective new Assistant Professor accrues if their mentor is on the search committee and can talk them up. Or, to maybe lesser extent, can talk the competitors down. Maybe your institution has COI rules in this case, and maybe the colleagues all know, because there’s the mentor, prominent on the CV. But what if it is a second generation? Maybe it isn’t so obvious that Candidate is the postdoc of Sonny who trained with your colleague on the search committee.
What about manuscript review? Well, here we probably have much lesser concern since the publication of papers is much less zero-sum than the awarding of NIH grants or Assistant Professorships. Yeah, yeah, impact factor, but ultimately you can publish just about anything…somewhere. But to the extent that citation homophily is a problem…it likely extends to academic family trees. And high impact journals do count. And peer review comments can either speed publication or mire it in the stickiest of muds. Those have real impact on the career as well….and ultimately on grant success.
And so the cycle of reinforced conservatism of science continues.
