Each institution's position in the ranking is determined by the cumulative D-indexes (Discipline H-index) of all affiliated scholars whose primary publication area is Psychology. The D-index reflects exclusively discipline-specific publication and citation data, providing a focused metric to assess performance within the field. This meticulous approach allows for an objective and consistent measurement of institutional excellence in Psychology research.
Scope and Criteria of the Ranking
The scope of the ranking encompasses an extensive review of 279,971 scientist profiles sourced from various bibliometric repositories. Specifically, 38,989 scientists specializing in Psychology were analyzed according to stringent eligibility requirements. To qualify for analysis, researchers were required to have a D-index of at least 30, with a majority of their publications in the domain of Psychology.
Additionally, the D-index threshold for highlighting top researchers is adjusted in increments of 10 based on the population of scholars in each discipline, ensuring representation of the top 1% of leading experts. To maintain focus on genuinely influential specialists, a proximity of 30% or less between a scientist’s broader H-index and their D-index was required. Notably, awards and achievements in the field of Psychology were also factored into the evaluation, further broadening the scope of excellence captured in the ranking.
Verification Procedures and Data Accuracy
Recognizing the limitations of raw bibliometric data, the research team undertook comprehensive manual verification of all scientist profiles. These profiles were cross-referenced with publications in a wide array of trusted sources to ensure validity and accuracy. While the ranking position is determined mainly by citation-based metrics (D-index and H-index) sourced from OpenAlex and CrossRef—the industry’s most prominent bibliometric databases—the volume of papers published in reputable journals and conference proceedings was also considered as a quality signal, albeit not directly influencing ranking positions.
The methodology underlying this ranking employs robust verification practices to provide an impartial and reliable assessment of individual and institutional research performance. We invite you to learn more about the specific processes and evaluation criteria by visiting our methodology page.
