"Citations
are important building blocks for status and success in science. We used a
linked dataset of more than 4 million authors and 26 million scientific papers
to quantify trends in cumulative citation inequality and concentration at the
author level. Our analysis, which spans 15 y and 118 scientific
disciplines, suggests that a small stratum of elite scientists accrues
increasing citation shares and that citation inequality is on the rise...top-cited
scientists increasingly reside in high-ranking universities in western Europe
and Australasia, while the United
States has seen a slight decline in elite concentration" https://www.pnas.org/content/118/7/e2012208118
In a certain way, the aforementioned finding helps to confirm what I wrote in a previous post in which i criticized a paper of two Full Professors of Economics at the world famous Columbia University (house of 84 Nobel laureates) https://pacheco-torgal.blogspot.com/2021/04/why-does-united-states-have-best.html
