A scientist's position within the ranking is determined by their D-index (Discipline H-index), a targeted metric that exclusively considers the researcher’s publication and citation record within the specific discipline under review, namely Social Sciences and Humanities. This approach ensures that the evaluation reflects meaningful impact and productivity within the relevant field.
Scope of Research and Eligibility Criteria
The ranking’s scope encompasses an extensive analysis of 279,971 scientist profiles across all disciplines identified through diverse bibliometric databases. Within this broader pool, 2,000 scientists specializing in Social Sciences and Humanities were specifically examined to compose the ranking.
To qualify for inclusion, candidates were required to meet a minimum D-index threshold of 30. Additionally, a majority of their tier publications had to be demonstrably situated within the Social Sciences and Humanities domains. Beyond bibliometric indicators, scientists’ awards and significant achievements in these disciplines were also factored into the evaluation process.
The D-index threshold for top researchers is dynamically calibrated in increments of 10, adjusted according to the estimated total number of scholars in each discipline. This methodology guarantees that the ranking includes the top 1% of leading experts within the field. Furthermore, to ensure alignment between general research impact and discipline-specific contributions, only scientists with a proximity of 30% or less between their overall H-index and D-index were considered.
Verification and Quality Assurance Practices
The team behind this ranking recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly output. To mitigate distortions and inaccuracies, each scientist profile was manually verified and cross-correlated against publications listed in a broad spectrum of trustworthy and authoritative sources.
While not directly influencing the ranking position, the volume of publications in prominent journals and conference proceedings constitutes a valuable secondary indicator of a scientist’s influence and contribution within their field. Research.com’s rigorous process places emphasis on transparency and verifiability, confirming that the final rankings are grounded in robust and carefully scrutinized data.
The final positioning is established using each scientist’s D-index, derived principally from OpenAlex and CrossRef data — among the most extensively curated and accessible bibliometric databases worldwide.
