Predicting if scientists will be stars: New formula reveals if young scientists will have brilliant future

Summary:
Will a young scientist's career be brilliant or ordinary? Now there's a crystal ball in the form of a new formula that accurately predicts a young scientist's success up to 10 years into the future and could be useful for hiring, tenure and funding decisions. The new formula is more than twice as accurate as a measure called the h index for predicting future success for researchers in the life sciences.

A medical school committee is weighing whether to hire a promising young neuroscientist. Will she have a brilliant future as a researcher, publish in top journals and nab abundant research funds?

If only there were a crystal ball. Wait, now there is!

A new Northwestern Medicine study published Sept. 13 in Nature offers the first formula that accurately predicts a young scientist's success up to 10 years into the future and could be useful for hiring and funding decisions.

Currently, hiring decisions are made using the instincts and research of search committees. Universities are increasingly complementing this with a measure of the quality and quantity of papers published, called the h index.

But the new formula is more than twice as accurate as the h index for predicting future success for researchers in the life sciences. It considers other important factors that contribute to a scientist's trajectory including the number of articles written, the current h index, the years since publishing the first article, the number of distinct journals one has published in and the number of articles in high impact journals.

The formula was developed in the lab of Konrad Kording, senior author of the Nature paper and associate professor in physical medicine and rehabilitation at Northwestern University Feinberg School of Medicine and a researcher at the Rehabilitation Institute of Chicago.

"The algorithm could be useful for hiring and tenure decisions as well as funding decisions, particularly at a time when funding agencies and hiring committees are dealing with vast number of applications," Kording said. "You want to fund someone who will have high impact in the future."

While the formula won't replace evaluation by a group of peers who examine scientific contributions and research depth, it could provide a valuable complementary tool, Kording noted. The predictions are targeted to a scientist at the level of assistant professor, someone within five to 15 years of writing his or her first paper as a Ph.D. student.

Kording and colleagues based and tested the formula on data from 3,293 scientists (3,085 neuroscientists, 57 Drosphila scientists and 151 evolutionary scientists) for whom they constructed a publication, citation and funding history.

The paper shows that the number of articles written, the diversity of publication and the number of top articles over time all become increasingly influential predictors of a scientist's success.

Perhaps publishing in many different journals leads to less overlapping populations of scientists who cite the work, Kording said, which leads to an increased number of citations for already published articles. The number of top journal publications also may give visibility to other papers of a scientist, both past and future.

The ability to predict future success also shows important discoveries are the result of ongoing hard work, not random luck.

"People think scientists sit there and all of a sudden have these strokes of genius that turn them into a superstar," Kording said. "In reality, people who have important scientific insights usually have been incredibly successful before."

The lead author of the paper is Daniel E. Acuna, a postdoctoral student in Kording's lab at Northwestern's Feinberg School of Medicine and a research affiliate in biomedical engineering at the McCormick School of Engineering and Applied Science.
