The bibliometric data underpinning the citation-based metrics used in this ranking were collected as of January 12, 2026. A scientist’s position within the ranking is determined by their Discipline H-index, or D-index, which exclusively accounts for publications and citation metrics relevant to the specific discipline of Psychology. This targeted approach ensures that impact is assessed with respect to domain-specific scholarly contributions.
Scope of Research and Eligibility Criteria
The ranking considered a total of 279,971 scientist profiles representing diverse academic fields extracted from a broad array of bibliometric data sources. From this pool, 1,000 scientists specifically associated with Psychology were examined in detail.
Eligibility for the ranking requires that a scientist’s D-index be at least 30, and importantly, that a majority of their tier publications are situated within the Psychology discipline. Additional qualitative considerations, such as notable awards and significant achievements in Psychology, were also factored into the evaluation.
The threshold for the minimum D-index required to consider researchers for inclusion is dynamic and set in increments of 10, reflecting the estimated total scholar population within each scientific discipline. This method guarantees that approximately the top 1% of leading scholars in each area are incorporated into the list. Furthermore, to ensure disciplinary relevance and focus, candidates must exhibit a proportional alignment between their general H-index and their D-index, with a proximity measure of 30% or less.
Verification Practices and Methodological Rigor
Recognizing the inherent limitations of relying solely on raw bibliometric data, the research team conducted thorough manual verification for each scientist’s profile. This process included cross-correlating publication records against a broad spectrum of trusted academic and professional sources to ensure accuracy and authenticity.
While the number of papers published in prominent journals and conference proceedings does not directly influence ranking positions, it serves as a valuable secondary indicator of a scientist's substantive contribution to the field. The use of the D-index metric, derived from authoritative data sources such as OpenAlex and CrossRef, remains the definitive criterion for ranking placement.
