Bibliometric data used to derive the citation-based metrics were collected as of January 12, 2026, guaranteeing the most current and comprehensive snapshot of scholarly output and impact. The ranking positions are determined by each scientist’s D-index (Discipline H-index), a refined bibliometric measure that accounts solely for papers and citation metrics within the examined discipline, thus emphasizing subject-specific scholarly influence.
Scope of Research and Criteria for Inclusion
The ranking process examined a total of 279,971 scientist profiles identified from a wide array of bibliometric data sources across all disciplines. Within the specific domain of Social Sciences and Humanities, 64 scientists were analyzed in detail. To qualify for inclusion in the ranking, a scientist’s D-index needed to be at least 30, with the majority of their tier publications concentrated within Social Sciences and Humanities.
In addition to bibliometric thresholds, a researcher’s awards and recognized achievements within the Social Sciences and Humanities field were also considered as part of the qualification process. The D-index threshold for top researchers is calibrated in increments of 10 based on the estimated total number of scholars within each discipline, thereby ensuring the inclusion of the top 1% of leading scholars in every respective field.
Moreover, a critical criterion for inclusion was the proximity of a scientist's general H-index to their discipline-specific D-index, which had to be 30% or less. This careful filtering ensures the ranking accurately reflects domain-focused scholarly impact rather than general cross-disciplinary citations.
Verification and Validation Practices
Understanding that raw bibliometric data alone cannot serve as an absolute indicator of scholarly contribution, Research.com has implemented rigorous manual verification and cross-correlation procedures. All scientist profiles underwent meticulous verification against publications documented in a broad spectrum of trustworthy academic sources.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position within the Research.com ranking, it is acknowledged as a significant secondary signal of a scientist’s contributions within their area of expertise.
The ranking positions are definitively established using the D-index, derived from the aggregated citation data in OpenAlex and CrossRef, reputable and transparent databases that provide a dependable foundation for the analysis.
