A researcher’s position in the ranking is determined by their D-index (Discipline H-index), a specialized metric that includes only those publications and citation records pertinent to the specific discipline under examination. This approach ensures that the ranking reflects a scientist’s impact and productivity strictly within the domain of Psychology, providing a focused and relevant evaluation.
Scope of Research
The ranking analysis commenced with the identification of 279,971 scientist profiles drawn from various bibliometric databases covering all disciplines. Among these, 11,419 profiles were specifically classified within the field of Psychology. To qualify for inclusion in the ranking, a scientist’s D-index had to be at least 30, with the majority of their tier publications concentrated in Psychology.
Additionally, consideration was given to a scientist's awards and achievements relevant to Psychology, further substantiating their standing in the field. The D-index threshold for evaluating top researchers is established in increments of 10, calibrated according to the total estimated number of scholars in each discipline. This structure ensures the inclusion of the top 1% of leading scholars in Psychology.
Moreover, to maintain consistency and field specificity, a proximity criterion is enforced whereby the difference between a scientist's overall H-index and their D-index is limited to 30% or less, ensuring that their disciplinary impact is proportionate to general citations.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure to evaluate academic contributions, the Research.com team has implemented thorough verification protocols. All scientist profiles included in the ranking underwent manual review and were cross-referenced against publications listed in a wide array of trustworthy sources to validate accuracy.
While the number of papers published in prestigious journals and conference proceedings does not influence the position in the ranking directly, it is regarded as a valuable secondary metric that signals a scientist’s research contributions and standing within the Psychology community.
The ranking positions are nonetheless firmly established based on each researcher’s D-index, derived from the curated and up-to-date information sourced from OpenAlex and CrossRef.
