Black and womenscientists are less likely to have multiple research grants, finds study yale jamanetworkopen
"Having multiple grants yields career advantages," said Mytien Nguyen, an M.D.-Ph.D. student at Yale School of Medicine and lead author of the study."Researchers are more likely to be retained and promoted, have more of a voice at their institutions and in shaping national research agendas, and have bigger labs that train more young researchers."
For the study, Nguyen and her colleagues first investigated how many NIH-funded researchers had multiple, simultaneous grants and whether that number had changed over time. They found that the percentage of researchers with three or more grants tripled from 1991 to 2020, increasing from 3.7% to 11.3% of NIH-funded researchers. Further, the percentage of researchers with four or more grants increased more than six-fold and those with five or more grants nearly 10-fold.
The researchers then evaluated the gender, racial, and ethnic composition of those with three or more NIH grants, which they refer to as"super principal investigators," or super PIs. There were two years within the three-decade span—1998 and 2015—when the NIH budget increased significantly. The researchers assessed funding rates throughout the time period and within the years before and following major budget increases.
The percentage of super PIs did increase across demographics from 1991 to 2020. In 1991, 2.1% of women and 4.4% of men were super PIs. By 2020, rates had increased to 8.7% and 13.1%, respectively. Similarly, at the start of the assessed period, 4.1% of white researchers, 4.0% of Asian researchers, 4.4% of Hispanic researchers, and 1.0% of Black researchers were super PIs. By 2020, those rates increased to 11.5%, 12.8%, 9.8%, and 5.6%, respectively.
"Concentrating resources among investigators who are more likely to be white and male has implications for the level of innovation we're going to see in the science that's produced. It's also going to affect the trust that people in the United States have in
