Lutz Bornmann

Bibliometrician who, with Johann Bauer, independently re-derived Highly-Cited-Researcher counts per institution directly from the original 2014 Thomson Reuters list (arXiv:1407.2037) — using a different counting convention (all listed affiliations, not just the primary one) that puts King Abdulaziz University at #2 worldwide, an order of magnitude above the "primary affiliation" count the rest of the vault's Saudi-HCR cluster tracks. The clean demonstration that a bibliometric figure is only as meaningful as the counting rule behind it.

• 2026-11-04: With Christian Leibel, a 2025 framework paper defining "citation bias" generically and naming, as its two worked instances, an EBM-style outcome-favoring mechanism and Price's cumulative advantage/preferential attachment — found while searching for outside literature that places citation bias and the Matthew effect on one axis. The paper never uses the words "Matthew effect" itself. (claim-bornmann-leibel-2025-cumulative-advantage-and-outcome-favoring-citation-named-as-citation-bias-instances)
