A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively includes publications and citations relevant to the examined discipline—in this case, Political Science. This approach ensures that the ranking reflects disciplinary expertise and impact, rather than a general research profile.
Scope of Research and Inclusion Criteria
The ranking analysis encompassed 279,971 scientist profiles identified from a variety of bibliometric sources covering all academic disciplines. Within this expansive dataset, 1,024 scientists specializing specifically in Political Science were examined. To qualify for inclusion in the ranking, a researcher was required to have a D-index of at least 20, and a majority of their tier publications needed to be situated within the Political Science discipline. Furthermore, a candidate’s documented awards and notable achievements in Political Science were factored into the evaluation process as complementary indicators of scholarly excellence.
The threshold for the D-index is calibrated to the size of each discipline and is incremented by 10 points depending on the total estimated number of scholars in that field. This methodology guarantees that the ranking incorporates the top 1% of leading scholars in their respective disciplines. Additionally, a scientific proximity criterion ensures a maximum 30% difference between a researcher’s overall H-index and their discipline-specific D-index, thus confirming the researcher’s focused contribution to Political Science.
Verification and Validation Practices
At Research.com, we acknowledge the limitations of raw bibliometric data as a sole evaluation tool and thus undertake meticulous manual verification of all scientist profiles included in the ranking. Each profile is cross-correlated against publications indexed by a broad spectrum of trustworthy academic sources to confirm accuracy and authenticity.
While the number of publications in high-impact journals and respected conference proceedings does not directly affect a researcher’s ranking position, it provides a valuable secondary signal of a scientist’s contribution to the discipline. The ranking position itself is firmly based on the D-index derived from OpenAlex and CrossRef records—two of the most prominent, transparent, and widely utilized bibliometric databases available to the research community.
