A scholar’s position within this ranking is determined by their D-index (Discipline H-index), a refined citation metric that specifically evaluates publications and citations within the targeted discipline of Psychology. This approach ensures relevance and precision by including only those works pertinent to the examined field, thus providing a discipline-focused measure of research impact.
Scope of Research and Ranking Criteria
The ranking assesses a dataset of 279,971 scientist profiles identified through an extensive review of bibliometric databases across all scientific disciplines. Within this dataset, 552 scientists specializing in Psychology were examined in detail. To qualify for inclusion in the ranking, a scientist’s D-index had to meet a minimum threshold of 30. Additionally, the majority of their tier publications—those considered most significant based on impact and prestige—were required to be within the area of Psychology. Awards and recognized achievements specific to the field of Psychology were also factored into the evaluation process, providing a holistic view of scholarly excellence.
The threshold for the D-index is dynamically calibrated, increasing in increments of 10 relative to the estimated total number of scholars per discipline. This methodology guarantees that the top 1% of leading experts are incorporated into each discipline-specific list. Furthermore, a check is employed to ensure the proximity between a scientist’s general H-index and their D-index does not exceed 30%, validating that their overall influence closely aligns with their impact within the discipline.
Additional Verification Practices
At Research.com, we recognize that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or research quality. Therefore, every scientist profile included in the ranking underwent rigorous manual verification and was cross-correlated against publications indexed in a wide array of trustworthy and domain-specific sources. This diligence ensures the accuracy and integrity of the profiles presented.
While the number of papers published in prestigious journals and conference proceedings does not directly alter a researcher’s ranking position, it serves as a valuable secondary indicator of their contribution to advancing scientific knowledge within Psychology. The ranking’s core metric, the D-index, is computed exclusively from the data procured from OpenAlex and CrossRef — two of the most trusted and comprehensive bibliometric databases accessible to the global research community.
