The ranking position of each institution is determined by aggregating the D-indexes (Discipline H-indexes) of all affiliated scholars whose primary research and publication area is Psychology. Importantly, the D-index reflects only publications and citation information specific to the assessed discipline, ensuring a precise evaluation of disciplinary contributions.
Scope of Research Considered
This ranking is based on the examination of 279,971 scientist profiles identified from a range of bibliometric data sources. From these, a focused analysis was performed on 38,989 scientists recognized for their work specifically in Psychology. To qualify for inclusion, each scientist needed to have a D-index of at least 30, with the majority of their significant publications in the field of Psychology.
An additional consideration was given to notable awards and achievements within Psychology, reinforcing the recognition of research excellence beyond mere citation counts. The threshold for inclusion among top researchers is incrementally set in steps of 10 D-index points, adapted according to the total number of researchers estimated per discipline, with careful calibration to ensure that the leading top 1% of scholars are incorporated into the list. Furthermore, a strict proximity requirement is enforced: a candidate scientist’s general H-index and their D-index should have a variance of no more than 30%. This approach ensures the disciplinary focus and credibility of those recognized. Awards and other forms of achievement in a scientist’s primary field were also integral factors in the selection process.
Verification and Quality Assurance Practices
Research.com is firmly aware that raw bibliometric data alone cannot, and should not, serve as the sole instrument for evaluating the scholarly output of researchers. Consequently, the methodology involved careful manual verification of all scientist profiles, which were diligently cross-referenced across a diverse spectrum of reputable publication sources. Although the count of articles published in prominent journals and conference proceedings is not a formal factor in researcher ranking, it is recognized as a valuable secondary indicator of research impact within a discipline.
Positions in the ranking are established based on each researcher’s H-index information, meticulously sourced from OpenAlex and CrossRef. These databases are widely acknowledged as the most trusted and established bibliometric resources available.
