Dashun Wang and Yifan Qian of Northwestern's Kellogg School published a study in PNAS yesterday examining US federal research funding. Grant proposals carrying stronger signals of AI-assisted writing were funded by the National Institutes of Health at a rate four percentage points higher than those without. The same proposals scored lower on semantic distinctiveness: they sat closer to work the agency had already funded. At the National Science Foundation, the authors found no significant relationship between AI-assisted writing and success.
