A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a measure tailored specifically to reflect impact within a particular discipline. Unlike the general H-index, the D-index includes only publications and citation data explicitly linked to the relevant research field—in this case, Psychology—thereby providing a discipline-sensitive assessment of scholarly influence.
Scope of Research and Eligibility Criteria
The ranking was constructed after examining 279,971 scientist profiles aggregated from diverse bibliometric data repositories across all academic disciplines, including 1,094 scientists identified specifically within the field of Psychology. To qualify for inclusion in the Psychology ranking, a scientist must have a D-index of at least 30 with the majority of their tier publications concentrated in Psychology. Additionally, consideration was given to scientists’ awards and achievements related to the discipline.
The D-index threshold is dynamically set in increments of 10 based on the estimated total number of scholars in each discipline, ensuring a balanced representation that includes the top 1% of leading researchers. Furthermore, rigorous criteria ensure that there is a proximity of 30% or less between a scientist’s general H-index and their Psychology-specific D-index, guaranteeing a consistent and meaningful disciplinary focus in the ranking.
Additional Verification Processes
The researchers behind this ranking acknowledge that raw bibliometric data alone cannot serve as an absolute evaluation metric for scholarly output. Consequently, all scientist profiles were manually verified and cross-correlated against publications indexed in a broad range of reputable sources to mitigate errors and ensure accuracy.
While not directly influencing a researcher’s position in the ranking, the volume of publications in prominent journals and high-quality conference proceedings is recognized as a valuable secondary indicator of a scientist’s contribution within Psychology. The final rank ordering is strictly based on the D-index information compiled from OpenAlex and CrossRef, both of which remain the most prominent, well-documented bibliometric resources available to the academic community.
