A scientist’s position in the ranking is determined using their D-index (Discipline H-index), a refined bibliometric measure that considers only published works and citation counts relevant to the discipline under examination — in this case, Psychology. This focused approach ensures the ranking accurately reflects scholarly impact within the specific field, rather than general citation influence.
Scope of Research and Qualification Criteria
The ranking methodology examined a total of 279,971 scientist profiles identified from various bibliometric data sources spanning all scientific disciplines. For Psychology specifically, 11 scientists meeting rigorous thresholds were analyzed and ranked.
To qualify for inclusion in the ranking, a scientist’s D-index was required to be at least 30, with the majority of their tier publications contributing to the field of Psychology. In addition to quantitative metrics, a researcher’s awards and notable achievements within Psychology were also considered, adding a qualitative dimension to the evaluation process.
The threshold for the D-index is dynamically adjusted in increments of 10 according to the estimated total number of scholars in each discipline, thereby guaranteeing that the top 1% of leading researchers are represented in the ranking. Furthermore, to ensure disciplinary relevance, there is an imposed proximity criterion whereby the difference between a scientist’s general H-index and their D-index must not exceed 30%.
Verification Practices and Ranking Methodology
The Research.com team recognizes that raw bibliometric data alone cannot be an absolute measure of a scholar’s scientific contribution. Accordingly, all scientist profiles included in the ranking underwent meticulous manual verification. This process involved cross-correlating author profiles and publication records against a broad spectrum of trustworthy academic sources to confirm accuracy and relevance.
While not directly influencing ranking positions, the number of papers published in prominent journals and respected conference proceedings was evaluated as an additional secondary indicator of a researcher’s impact and contribution to Psychology.
Positions in the ranking are established primarily using each researcher’s D-index calculated from information gathered through OpenAlex and CrossRef, which remain the most prominent and well-established bibliometric databases available to the research community.
