The 2nd edition of Research.com ranking of the best scientists in the
discipline of Psychology relies os data
combined from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a scholar’s
D-index (Discipline H-index), which takes into account only
publications and citation values for an examined discipline.
The range of our Psychology research
Research.com’s best scientists ranking is a reliable lineup of leading researchers from the area of Psychology, created using a meticulous study of 166,880 scholars determined from various bibliometric data sources. For the area of Psychology, more than 15018 scholars were examined.
What is D-index approval threshold for Psychology
The D-index threshold for accepting a scientist to be evaluated is placed at 30 if the majority of of their publications are in the area of Psychology. The acceptance requirements for researchers to be considered into the ranking of top scholars are based on the D-index, proportion of the publications made within the selected discipline as well as the awards and achievements of the scholars. The D-index threshold for listing best scholars is set as an increment of 10 depending on the overall number of scientists assessed for each scientific field whilst guaranteeing that the top 1% of best scholars are incorporated into the list. We estimate a proximity of 30% or less between a scientist’s general H-index and their D-index.
Other verification rules
Because our primary goal is to make sure that only actual scientists are included in our ranking we believe that metrics are never meant to be a full means to assess the output of researchers. This is why we manually verify each profile and cross-correlate it against publications in a broad range of trustworthy sources. Even though it’s not a factor impacting a scholar’s position in our ranking, the quantity of papers published in well-known journals and conference proceedings should be a valuable secondary indication of their contribution to research in a given discipline. Position in the ranking is established using each scholar’s D-index using metrics collected from OpenAlex and CrossRef, which are the most credible and well-known bibliometric databases of this kind accessible to the scientific community. A thorough overview of our research process can be found on our methodology page.
Our goal is to inspire scholars, businessmen and administrative bodies around the world to investigate where prominent experts are heading and to give a way for the whole research community to get to know who the leading experts in specific fields of research, in different countries, or even within research institutions are.
