David Pendlebury
Clarivate / Institute for Scientific Information's Head of Research Analysis. His own words — reproduced verbatim in a SIRIS Academic report rather than paraphrased — are the vault's Tier-1 primary voice on how Clarivate tightened its Highly Cited Researchers evaluation methodology ahead of the 2023 list (hyper-authorship, excessive self-citation, unusual collaborative-citation patterns, and institutional expressions of concern as exclusion factors), though he has not himself made any Saudi-specific statement the vault has found.
Updates
- 2026-07-30: A second Pendlebury-authored document (his "Highly Cited Researchers 2023: Evolving Evaluation Policy" blog post) was checked directly this session and, like his April 2023 statement, contains no Saudi-specific text — corroborating rather than changing the existing finding.
