Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Psychology Scientists in Belgium Ranking is primarily based on comprehensive bibliometric data collected from prominent and reputable sources, including OpenAlex and CrossRef, alongside multiple other scientometric databases. These extensive data repositories provide a broad and detailed foundation for assessing research output and citations. The bibliometric data used to calculate citation-based metrics were collected on January 12, 2026, ensuring the ranking reflects the most up-to-date information available at the time of compilation. The ranking methodology centers around the D-index (Discipline H-index), a refined bibliometric indicator that considers only publications and citations specifically within the examined discipline, in this case, Psychology. This ensures a focused and discipline-specific evaluation of researcher impact and productivity.
Scope of Research and Ranking Criteria
This edition examined a total of 279,971 scientist profiles aggregated from a diverse range of bibliometric data sources covering all scientific disciplines. Within this wide dataset, 155 scientists specializing in Psychology were identified and evaluated for potential inclusion in the ranking. To qualify, a scientist’s D-index had to meet or exceed the threshold of 30, and the majority of their tier publications were required to be within the domain of Psychology. Additionally, scientists’ awards and recognized achievements in the field played a role in the qualification process.
The D-index threshold is dynamically set in increments of 10, calibrated based on the estimated total number of scholars in each discipline. This approach ensures that the ranking consistently captures the top 1% of leading scholars within Psychology. Further, a requisite proximity criterion is applied whereby the difference between a scientist’s overall H-index and their discipline-specific D-index is maintained at 30% or less, securing a balanced and representative measure of impact both broadly and within the discipline.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or quality, the Research.com team implemented meticulous manual verification procedures. Each scientist profile included in the ranking was cross-checked against publications documented in a wide array of trusted sources to confirm accuracy and relevance. While not directly influencing the ranking position, the number of papers published in leading journals and prominent conference proceedings is considered a valuable secondary indicator of a researcher’s contribution to their field.
The D-index remains the principal metric for establishing a scientist’s position in the ranking, calculated based on the robust and expansive bibliometric data from OpenAlex and CrossRef, which are broadly recognized as leading databases serving the global research community.
