The bibliometric data used to devise the citation-based metrics underpinning the ranking were captured on January 12, 2026, ensuring currency and relevance. A researcher's position within the ranking is determined by their D-index (Discipline H-index), a refined metric that isolates papers and citation counts specifically within the examined discipline, in this case, Political Science. This discipline-specific focus allows for a more accurate reflection of scholarly impact within the relevant field.
Scope of Research and Qualification Criteria
The ranking's foundation lies in an extensive evaluation of 279,971 scientist profiles drawn from a variety of bibliometric databases across all academic disciplines. Within this vast dataset, 11 scientists specializing in Political Science met the criteria for inclusion in the ranking.
To qualify, a scientist's D-index must be at least 20, reflecting a high level of scholarly output and citation impact concentrated in Political Science. Additionally, the majority of a qualifying scientist’s tier publications must be within the Political Science domain. Consideration was also given to awards and achievements recognized specifically within the field of Political Science, ensuring a comprehensive picture of professional distinction.
The D-index threshold for top researchers is calibrated in increments of 10, relative to the estimated total number of scholars per discipline. This stepwise threshold ensures that the top 1% of leading scholars are incorporated in the ranking. Moreover, a prerequisite proximity criterion requires that the difference between a scientist’s general H-index and their D-index not exceed 30%, preserving the alignment between overall research impact and discipline-specific expertise.
Verification Practices and Methodological Rigor
Recognizing that raw bibliometric data alone cannot serve as an absolute tool for evaluating scholarly output, the Research.com team has implemented a thorough manual verification process for all scientist profiles. This process includes cross-correlation against publications indexed in a broad range of trustworthy and authoritative sources to ensure accuracy and mitigate errors or misattributions.
Although the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it provides a valuable secondary signal of a scientist’s contribution to their specific research area. The core ranking metric—D-index—is based on data curated from OpenAlex and CrossRef, which remain the most reliable and widely employed bibliometric databases of their kind.
