Data Sources and Citation Metrics Collection
The 5th edition of the Research.com Best Psychology Scientists in Mexico Ranking is primarily constructed using comprehensive bibliometric data sourced from OpenAlex and CrossRef, complemented by multiple other reputable data sources. These databases represent some of the most extensive and authoritative repositories available within the research community, enabling rigorous and accurate citation analysis. The citation-based metrics, which form the backbone of the ranking, were meticulously compiled on January 12, 2026.
A scientist’s position within the ranking is determined by their Discipline H-index, commonly referred to as the D-index. Unlike a general H-index, the D-index is discipline-specific; it exclusively aggregates papers and citations relevant to the examined field—in this case, Psychology. This ensures that the ranking reflects a researcher’s impact and influence specifically within the psychology discipline.
Scope of Research and Eligibility Criteria
For the purpose of this ranking, an extensive examination was conducted on 279,971 scientist profiles drawn from diverse bibliometric sources encompassing all disciplines. Within this broader dataset, 1,XXX scientists specializing in Psychology were identified and considered. To qualify for inclusion in the Psychology ranking, a researcher must possess a D-index of at least 30, with the majority of their tier-level publications attributable to the psychology discipline. Additionally, recognition of scientists’ awards and distinguished achievements within the field played a supplementary role in the evaluation process.
The D-index threshold for identifying top researchers is dynamically set in increments of 10, contingent on the estimated population of scholars in each discipline. This adaptive mechanism ensures that the ranking consistently incorporates the top 1% of leading experts within the field. Furthermore, a requirement that holds a proximity of 30% or less between a scientist’s overall general H-index and their D-index is enforced, safeguarding that the ranking reflects specialization and excellence in Psychology specifically.
Verification Practices and Methodological Transparency
The Research.com team acknowledges that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. To address this, every scientist profile included in the ranking underwent meticulous manual verification and was cross-referenced against publications from a wide array of trusted and authoritative sources. This rigorous validation process reinforces the reliability and credibility of the presented ranking.
Although not directly factored into the final position of a researcher in the ranking, the quantity of publications in prominent journals and conference proceedings forms an important supplementary signal of a scientist’s contributions within their domain. The core ranking metric, the D-index, was established using citation information drawn from OpenAlex and CrossRef, recognized as the most prominent and widely adopted bibliometric databases available to the academic community.
