A scientist's position within the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the papers and citation counts within the examined discipline of Psychology. This discipline-specific approach ensures that evaluations reflect a researcher's impact and contributions accurately within their primary field of expertise.
Scope of Research and Selection Criteria
The ranking process examined a dataset comprising 279,971 scientist profiles from diverse bibliometric sources covering all scientific disciplines. Within this extensive dataset, 272 scientists specialized in Psychology were identified and specifically analyzed. To qualify for inclusion in the Psychology ranking, a scientist must have achieved a minimum D-index of 30, and the majority of their highest-tier publications had to be categorized within the area of Psychology.
In addition to bibliometric thresholds, recognition of awards and notable achievements within the field of Psychology was factored into the evaluation, reinforcing the significance of a researcher’s professional contributions beyond citation metrics.
The D-index threshold for consideration of top researchers is calibrated in increments of 10, adjusted according to the estimated size of the scholar population per discipline. This methodology strategically ensures that at least the top 1% of leading scholars are represented in the list. Furthermore, the ranking methodology maintains a proximity criterion whereby a scientist’s general H-index and their Discipline H-index (D-index) differ by no more than 30%, emphasizing consistency in impact both within and beyond the specific discipline.
Verification Practices and Methodological Rigour
Understanding that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the Research.com team undertook meticulous manual verification of all scientist profiles included in the ranking. Each profile was cross-correlated against publication records from a wide range of trustworthy and authoritative sources to ensure accuracy and to mitigate issues stemming from data incompleteness or misattribution.
While not directly influencing a researcher’s position in the ranking, the number of publications in prominent journals and conference proceedings is acknowledged as a valuable secondary indicator of a scientist’s contribution to the field. The primary determinant for ranking position remains the D-index, based on data derived from OpenAlex and CrossRef—widely recognized and utilized bibliometric databases within the global research community.
