Data Sources and Citation Metrics
The 5th edition of the Research.com Best Psychology Scientists in Israel Ranking is primarily constructed using comprehensive bibliometric data sourced from OpenAlex and CrossRef, alongside multiple other reputable data repositories. These databases provide extensive, up-to-date publication and citation records essential for deriving citation-based metrics. The bibliometric data used to devise the metrics for this ranking were collected as of January 12, 2026. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a specialized metric that reflects a researcher’s impact within a specific disciplinary domain by including only papers and citation counts relevant to that discipline.
Scope of Research and Qualification Criteria
The ranking undertakes a broad examination of 279,971 scientist profiles compiled from diverse bibliometric data sources spanning all scientific disciplines, with a focused analysis on 145 scientists specializing in Psychology. To qualify for inclusion in the Psychology ranking, a scientist’s D-index must be at least 30, and the majority of their tier publications must fall within the Psychology discipline. Additionally, scientists’ awards and notable achievements in Psychology were considered to ensure a holistic evaluation.
The D-index threshold is dynamically calibrated in increments of 10, relative to the estimated number of scholars within each discipline, guaranteeing the inclusion of the top 1% of leading researchers. Moreover, to ensure alignment of disciplinary focus, the difference between a scientist’s general H-index and their D-index is required to be 30% or less, underscoring consistency between their overall impact and discipline-specific influence.
Additional Verification Practices
The Research.com team recognizes that raw bibliometric data should not be regarded as an absolute measure of scholarly output or impact. To uphold the rigor and credibility of the ranking, all scientist profiles were manually verified and cross-referenced against publications listed in a wide array of trustworthy academic sources. While the quantity of papers published in prominent journals and conference proceedings does not directly affect a researcher’s position in the ranking, it is acknowledged as a valuable secondary indicator of contribution within a given field.
The ranking positions are ultimately established using the D-index values calculated from data provided by OpenAlex and CrossRef—the most prominent and widely respected bibliometric databases available to the global research community.
