Making research funding more efficient

Wednesday, January 2, 2019 - 12:30

As scientific funding becomes increasingly scarce, professors in STEM fields spend more time in their offices writing grant applications: by one estimate, as much as one-fifth of their research time. That takes time and energy away from teaching students, training young researchers and making discoveries that boost our collective knowledge and well-being.

Two scientists believe that, with professors vying for such a small pool of funds, the grant-application process has become a competition not over who has the best ideas, but who is the best at writing grant applications. In a paper published Jan. 2 in the journal PLOS Biology, co-authors Carl Bergstrom, a professor of biology at the University of Washington, and Kevin Gross, a professor of statistics at North Carolina State University, use the economic theory of contests to illustrate how this competitive system has made the pursuit of research funding inefficient and unsustainable. They show that alternative methods, such as a partial lottery to award grants, could help get professors back in the lab where they belong.

Funding thresholds for grant applications have tightened steadily since the 1970s. In 2003, only the top 20 percent of research project grant applications to the National Institute of Allergy & Infectious Diseases were funded. In 2013, the success rate had plummeted to 8 percent. Gross and Bergstrom argue that the funding pool has grown so small relative to the number of applicants that the nature of the grant-application process had changed.

“When agencies only fund the top 10 or 20 percent, they aren’t just separating bad ideas from good ideas,” said Bergstrom. “They’re also separating good from good.”

“This has two effects on the grant-application process,” said Gross. “First, professors must apply for more and more grants before they’re awarded one. Second, the application process becomes a contest to determine who can write the best grant proposals — so professors spend more and more time trying to perfect each individual application.”

In their paper, Bergstrom and Gross illustrate how the grant-application process is consistent with economic contest models. They show how funding a relatively small fraction of grant applications — such as the top 10 or 15 percent — makes the practice of science inefficient: The negative costs associated with trying to produce the best grant application could potentially outweigh the economic value of the science produced.

If agencies funded a higher percentage of applications, professors could spend less time trying to write the perfect grant application. In addition, funding agencies wouldn’t have to subjectively choose winners among high-quality proposals that are all based on sound science. But this option would require significantly expanding funding to agencies like the NIH and the NSF, a politically difficult task.

Using the economic theory of contests, Gross and Bergstrom modeled a controversial alternative: awarding grants instead by partial lottery. Under a partial lottery system, funds are awarded by random draw among a pool of high-ranking grants — the top 40 percent, for example. Since applicants would be aiming to clear a lower bar for a smaller prize — a shot at the lottery instead of a guaranteed payout for winning proposals — the contest theory model predicts that applicants would spend less time trying to perfect their applications, Bergstrom said.
