A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator which accounts exclusively for publications and citations within the specific discipline under examination—in this case, Psychology. This discipline-focused approach provides greater precision in evaluating scholarly impact within the relevant research area.
Scope of Research and Inclusion Criteria
The ranking encompasses a large-scale examination of 279,971 scientist profiles identified across diverse bibliometric data repositories covering all academic disciplines, with a focused analysis of 142 scientists specialized in Psychology. To qualify for inclusion in the Psychology ranking, a researcher’s D-index had to be at least 30. Additionally, the majority of their tier publications needed to be situated firmly within the Psychology field.
Beyond bibliometric thresholds, a scientist’s awards and achievements in Psychology were carefully considered to refine the selection of leading experts. The D-index threshold for recognizing top researchers is dynamically adjusted in increments of 10, commensurate with the estimated total scholar population per discipline, while ensuring the inclusion of the top 1% of researchers. Furthermore, a qualifying candidate’s general H-index and D-index must be in close proximity, with a divergence of no more than 30%, to confirm discipline-specific excellence.
Verification and Methodological Rigor
The Research.com team recognizes that raw bibliometric data alone cannot fully capture the nuances of scholarly contributions. Accordingly, all scientist profiles were subjected to thorough manual verification and cross-correlation against publications indexed in a broad spectrum of trusted academic sources. This rigorous process reinforces the credibility and accuracy of the ranking.
While not directly influencing ranking positions, the number of publications in prestigious journals and conference proceedings is acknowledged as a valuable secondary indicator of a scientist’s impact within Psychology. The final ranking order is determined exclusively by each researcher’s D-index, calculated using data from OpenAlex and CrossRef—two of the most prominent and widely respected bibliometric databases accessible to the research community.
