The flawed Clarivate list of influential scientists: The unsuccessful bid of third methodological changes to rectify flaws


The annual list of "top" scientists compiled by Clarivate Analytics remains a subject of ongoing controversy. Following the year 2018, and in response to significant criticism from the scientific community, Clarivate Analytics introduced a new category called "Cross-Field." In addition, they made the decision to exclude articles featuring more than 30 affiliations. This year, a fresh alteration to their methodology has come to light. Clarivate Analytics decided to remove (evil) articles with more than 30 authors.

However, the question arises: why specifically 30, and not 29, 28, 27, 26, 25, and so on? Curiously, Clarivate Analytics provides no insight into this choice, possibly due to the inherent secrecy that appears to be central to its operations. Alternatively, it may be reluctant to acknowledge that its methodology is fundamentally flawed, a sentiment expressed by numerous researchers in the field., such as Docampo & Cram (2019), Asknes &Aagaard (2021), or more recently Koltun &Hafner (2021) https://pacheco-torgal.blogspot.com/2021/11/evaluating-researchers-in-fast-and.html

To Clarivate Analytics' great misfortune, some Stanford University researchers went out of their way to try to solve the aforementioned shortcomings. And fortunately, they successfully generated a list of top scientists that markedly enhances the scientific reliability. https://elsevier.digitalcommonsdata.com/datasets/btchxktzyw/3?fbclid=IwAR1vdz  

This new list of top scientists effectively addresses the significant issue of articles with numerous authors, ranging from tens to hundreds or even thousands. Moreover, it rectifies the deficiencies present in Clarivate Analytics' list, which often combines researchers from different fields, overlooking the distinct citation patterns, as thoroughly demonstrated by Lillquist and Green.https://link.springer.com/article/10.1007/s11192-010-0162-3

Last but not least, the Stanford University researchers' list (in contrast to the flawed Clarivate Analytics list) upholds a commitment to transparency by providing open access to raw data for all interested parties.
