The 2nd edition of Research.com ranking of the best scientists in the
arena of Psychology is based on data
combined from various data sources including OpenAlex and
CrossRef. The bibliometric data for estimating the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a scientist's
D-index (Discipline H-index), which only includes
publications and citation metrics for an examined discipline.
The focus of our Psychology research
Research.com’s best scientists ranking is a credible lineup of leading scientists from the discipline of Psychology, established by means of a thorough study of 166,880 scholars identified from a variety of bibliometric data sources. For the field of Psychology, as many as 15018 researchers were analysed.
What is D-index approval threshold for Psychology
The D-index threshold for accepting a researcher to be examined is set to 30 if the majority of of their publications are in the discipline of Psychology. The inclusion factors for researchers to be considered into the ranking of top researchers are based on the D-index, ratio of the publications made within the selected area in addition to the awards and achievements of the scientists. The D-index threshold for listing leading scientists is set as an increment of 10 depending on the total number of scholars assessed for each discipline whilst guaranteeing that the top 1% of leading scientists are added into the ranking. There should be a proximity of 30% or less between a scientist’s general H-index and their D-index.
Other verification practices
Because our main goal is to make sure that only actual scholars are mentioned in Research.com ranking we believe that metrics are never meant to be a complete means to quantify the contributions of scientists. This is why we manually inspect each profile and cross-correlate it against publications in a wide range of reliable sources. Even though it’s not a factor impacting a scientist’s position in our ranking, the quantity of papers published in major journals and conference proceedings should constitute a valuable secondary implication of their contribution to research in a selected field of study. Position in the ranking is determined by every researcher’s D-index according to data collected from OpenAlex and CrossRef, which are the most trustworthy and well-established bibliometric databases of this type open to the research community. A comprehensive definition of our research process can be found on our methodology page.
Our aim is to motivate researchers, entrepreneurs and administrative bodies around the world to examine where leading experts are heading and to provide an opportunity for the entire research community to get to know who the leading experts in specific disciplines, in various countries, or even within research institutions are.
