By analyzing a global sample of 4 million authors and 26 million scientific papers, this study finds that the top 1% most-cited scientists have increased their cumulative citation shares from 14 to 21% between 2000 and 2015 and that the Gini coefficient for citation imbalance has risen from 0.65 to 0.70. The growing citation concentration should be understood in the context of diverging trends in publication and collaboration activities for the top 1% compared to the “ordinary scientist.” Our study raises intriguing questions about how rising inequalities will shape the evolution of science. https://www.pnas.org/content/118/7/e2012208118
