The citation-based metrics that underpin the ranking were collected on January 12, 2026, providing a current and robust dataset for analysis. A researcher’s position in the ranking is determined exclusively by their D-index (Discipline H-index), a metric that aggregates publication and citation counts solely within the examined discipline, Political Science. This ensures that the ranking reflects expertise and impact specifically relevant to the field under consideration.
Scope of Research and Eligibility Criteria
Extensive bibliometric data spanning all disciplines was used to identify a total of 279,971 scientist profiles. Out of these, 1,002 scientists were specifically categorized within the field of Political Science. To qualify for inclusion in the ranking, a scientist’s D-index needed to be at least 20, and a majority of their tier publications had to be within Political Science.
In addition to quantitative bibliometric standards, consideration was also given to awards and other significant achievements in Political Science, thereby enriching the evaluation with qualitative factors. The D-index threshold for selecting top researchers is adjusted in increments of 10 based on the estimated total number of scholars per discipline, a methodology designed to ensure that the top 1% of leading experts are included. Furthermore, a criterion is enforced such that the proximity between a scientist’s general H-index and their D-index must not exceed 30%, thereby maintaining focus on discipline-specific excellence.
Additional Verification Practices
The research team behind this ranking acknowledges that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. Consequently, all scientist profiles were subjected to manual verification and cross-correlation against publications indexed in a broad spectrum of reputable academic sources. This rigorous verification process enhances the reliability and trustworthiness of the ranking.
Although the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position in the ranking, it remains an important secondary signal of an individual’s contribution to Political Science research.
Researchers’ standings are ultimately established using their D-index calculated from the comprehensive data compiled by OpenAlex and CrossRef. The meticulous integration of multiple credible bibliometric databases establishes a solid foundation for the ranking’s accuracy.
