Helping connect you with the NIH perspective, and helping connect us with yours

Perspectives on Evidence-based Funding

At the NIH Regional Seminar this past May, I had the pleasure of giving the keynote talk and presenting different perspectives on how NIH can further the impact of our research funding. Some of the topics I presented in this talk will be familiar to frequent Open Mike blog readers – our concerns about the hypercompetitive nature of applying for NIH support, for example. Others we haven’t discussed in depth here yet – such as how we might measure the contributions of NIH-supported research to treating diseases. My staff recorded this talk and has made it available to you on the NIH Grants YouTube channel. If you’re interested in the topics covered here on the blog (which I hope you are, since you are reading this now!) then you may be interested in this talk.

  1. Mike,

    While it is possible that we eventually see diminishing returns as funding to a single PI increases, the graph that you present during the discussion starting at 23:05 fails to establish this.

    The immediate problem is that you are showing a log-log graph, but making claims about decreasing returns, i.e., about the concavity of the graph. Concavity is not preserved across the log transformation. In other words, curves that exhibit decreasing returns on a log-log scale may exhibit increasing returns when plotted on a linear scale. Therefore the mere concavity of the graph you show does not demonstrate the decreasing incremental returns it is purported to show.

    There’s a more fundamental problem here however. Rather than comparing how individual investigators respond to changes in funding, you have compared outputs across different investigators receiving differing amounts of funding. The problem with this approach is that if review panels are doing anything useful, investigators’ funding will vary systematically with their abilities to convert funding into impactful work. As a result, the production function that you have inferred from data is unlikely to adequately predict the consequences of actual funding changes.

    I realize these arguments are difficult to follow without images and equations. We have addressed each of these points in great detail in a pair of blog posts. I am not permitted to post links here, but one can find them easily by searching for “Case study: NIH’s Rule of 21” or something similar.

    Best regards,

    Thanks for all good offices of NIH. Anticipate International ESIs inclusion to these new initiatives
