All bibliometric data used to calculate the citation-based metrics were gathered on January 12, 2026. The ranking methodology relies on the D-index (Discipline H-index), a refined metric that considers only the papers and citation counts relevant to the specific discipline under examination. This ensures that a scientist’s position in the ranking accurately reflects their impact within the Social Sciences and Humanities.
Scope of Research and Qualification Criteria
The scope of this ranking encompasses a thorough review of 279,971 scientist profiles identified across multiple bibliometric sources, spanning all academic disciplines globally. Within this dataset, 3 scientists from Social Sciences and Humanities in Iceland were specifically examined.
To qualify for inclusion in the ranking, a scientist must have a D-index of at least 30, with a majority of their tier publications concentrated in the Social Sciences and Humanities. Additionally, the scientist’s awards and achievements relevant to this field were considered as supporting factors in the evaluation process.
The D-index threshold for identifying top researchers scales in increments of 10, calibrated according to the estimated total number of scholars in each discipline. This approach guarantees inclusion of the top 1% of leading scholars in their respective fields. Furthermore, a proximity criterion is applied: the difference between a scientist’s general H-index and their D-index should be 30% or less, ensuring the ranking focuses on specialists with substantial contributions to Social Sciences and Humanities.
Verification and Validation Practices
The researchers responsible for this ranking are acutely aware that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. To address this, each scientist’s profile was manually verified and cross-correlated against a broad spectrum of trustworthy publication sources. This meticulous verification process strengthens the credibility and reliability of the ranking.
While not directly influencing the final placement in the ranking, the number of papers published in prominent journals and conference proceedings serves as a valuable secondary indicator of a scientist’s contributions to their field.
The final positions in the ranking are determined using each researcher’s D-index, derived exclusively from data curated by OpenAlex and CrossRef, which are among the most recognized and authoritative bibliometric databases available to the research community.
