A fundamental component determining a scientist's position in the ranking is the D-index (Discipline H-index). This metric is a discipline-specific variant of the traditional H-index and accounts exclusively for a researcher's publications and citations within the examined field of Political Science. The D-index thereby provides a focused assessment of scholarly impact relevant to the discipline.
Scope of Research Covered
To construct the ranking, a total of 279,971 scientist profiles were examined, encompassing all academic disciplines as identified through a comprehensive review of varied bibliometric resources. Within Political Science specifically, 70 scientists were analyzed in detail.
Qualification for inclusion in this specialized ranking required that a scholar possess a minimum D-index of 20, ensuring that only researchers with significant disciplinary impact are represented. Additionally, a majority of each scientist’s top-tier publications needed to be situated within Political Science. Recognition of scientists' awards and notable achievements within the field was also taken into consideration to provide a richer, multidimensional evaluation.
The threshold for the D-index is calibrated by increments of 10, adjusted according to the estimated population of researchers within each discipline. This approach ensures that the top 1% of leading scholars are consistently incorporated, maintaining both exclusivity and representativeness. Furthermore, to confirm disciplinary focus, only profiles with a proximity of 30% or less between their general H-index and D-index were included, mitigating the risk of cross-disciplinary inflation of impact metrics.
Additional Verification Practices
We recognize that raw bibliometric data, while foundational, should never be regarded as an absolute measure of scholarly output or quality. In light of this, every scientist profile included in the ranking was subjected to meticulous manual verification. This process involved thorough cross-correlation against publications indexed in a wide range of trusted academic sources, thereby ensuring the integrity and reliability of the data.
While not directly influencing the ranking position, the volume of papers a scientist has published in prominent journals and conference proceedings offers a valuable secondary indication of their contributions to Political Science research. We emphasize that positions in the ranking are established strictly by the D-index, synthesized from data acquired through OpenAlex and CrossRef — the foremost and most extensively utilized bibliometric databases available to the research community today.
