Institutional rankings are determined by aggregating the D-indexes (Discipline H-index) of all ranking scholars affiliated with each institution, focusing on those whose principal publication activity is within the domain of Psychology. The D-index is a specialized metric, accounting exclusively for the publications and citation data related to a scholar’s work in the examined discipline, ensuring the rankings reflect true disciplinary impact.
Scope of Research Assessed
The scope of this ranking is both extensive and precise. In total, 279,971 scientist profiles were identified through a diverse array of bibliometric sources, of which 38,989 researchers working specifically in Psychology were further analyzed. To uphold the highest standards for inclusion, a qualifying D-index threshold of 30 was implemented for each scientist, with the requirement that the majority of their significant publications be in the discipline of Psychology.
The ranking also takes into account various distinctions in the field, including scientists’ awards and notable achievements. The selection process ensures that the D-index threshold required for considering leading researchers increases in increments of 10 depending on the total estimated number of scholars in each discipline, with the aim of guaranteeing the inclusion of the top 1% of experts globally. Additionally, to ensure the quality and specificity of expertise, there must be a proximity of 30% or less between a scientist’s overall H-index and their D-index in Psychology. Recognition in the field through awards is considered as both a testament to scientific impact and research leadership.
Verification Practices and Data Integrity
To maintain the highest degree of credibility, all scientist profiles undergo manual verification. This process includes cross-referencing publication records across a wide range of trustworthy and well-established sources, ensuring accuracy beyond what raw bibliometric data alone can provide.
The researchers developing this ranking recognize that citation data and publication metrics should not be viewed as absolute measures of scholarly impact. Nevertheless, counts of articles in leading journals and conference proceedings, while not directly influencing a researcher’s ranking position, remain valuable as a supplementary indicator of research contribution within a specific scientific field.
The ultimate position in the ranking is determined by the H-index of each researcher, reflecting data from OpenAlex and CrossRef — the foremost bibliometric databases available to the academic community.
