worried about Science Ethics? 19.11.2024 Clarivate removes another 2000 researchers from the list of "highly cited researcher" (HCR, with a total of ca. 'top-cited' 7000), see their analysis. After the former removals (2023: 1000, 2022: 500, 2021: 300), this makes a staggering total of 35% of removed HCR researchers! Self-evidently, Clarivate is frightened to death: selling numbers is their business model, and if people game the system unnoticed, their numbers are not worth a penny...

worried about Science Ethics? 31.01.2024: according to a recent report in the journal 'Science', the recent removal of 1000 researchers from Clarivate's HCR list concerns the entire field of mathematics, due to the formation of a citation cartel
(read more), pushing unknown authors of irrelevant papers into the HCR list.
Apparently, Clarivate is mortally terrified to loose it's business model, as 'citation gaming' becomes a popular 'sport' among certain researchers, fulfilling Goodhart's law.
Citation Cartels are found also in other fields and countries, see e.g. Clarivate Crackdown on Biochar Citation Cartel'' ...for our own research field, take a look also at these profiles (example-1, example-2), to conceive a qualified opinion.
...if you are interested in these issues, take a look at my seminar on Scientific Integrity Decline in Current Materials Research: Insights & Vistas Beneath the Tip of the Iceberg.

11.12.2023 Thank you, MªCarmen to invite me to the Department of Physical Chemistry, Faculty of Sciences, University of Málaga, to talk about Scientific Misconduct in Current Materials Research: Aspects, Conditions and Perspectives (oraganizer: MªCarmen Ruiz Delgado)
worried about Science Ethics? 24.11.2023 Clarivate removes +1000 researchers from the list of "highly cited researcher" (HCR), see their analysis,
and the article in El País. Already, in 2022, Clarivate removed 500 researchers, and 300 in 2021. Thus the total amount of removed HCR researcher amounts staggering 21%!
The Course on Theoretical Methods for Simulation of Materials (Coord. J. Gierschner), within the European Master in Theoretical Chemistry and Computational Modelling (TCCM), took place at IMDEA Nanoscience, 27.11.-01.12.2023.

10.11.2023: seven researchers from IMDEA Nanoscience are listed among the co-called "2% most influential" in the 2023 update of the original 2019 survey by Ioannidis et al. The list also includes group leader JG [subfield Chemical Physics; 0.8% (#9 in ES) in 2022, 1.6% for the entire career], read more
...but caution: lists based on citation indices can – as all quantitative measures – be manipulated by authors, here in particular through scientific hyperproduction (inter alia by AI-assisted 'salami papers' and 'honorary' authorships), excessive self-citation and citation cartels (of authors a/o institutions a/o journals), which are in fact increasingly seen in the community...
...therefore, Clarivate's predictable statement that "highly cited researchers have demonstrated significant and broad influence reflected in their publication of multiple highly cited papers over the last decade" becomes increasingly erroneous, evidently fueling scientific misconduct by creating revenants (German: "Wiedergänger") of such 'highly-cited researchers' as a grotesque farce...
