Best Psychology Scientists in Japan

The 2nd edition of ranking of the best scholars in the field of Psychology is based on data combined from a wide range of data sources including OpenAlex and CrossRef. The bibliometric data for evaluating the citation-based metrics were gathered on 21-12-2022. Position in the ranking is based on a researcher’s D-index (Discipline H-index), which only includes publications and citation metrics for an examined discipline.

The focus of our Psychology research’s best scientists ranking is a reliable list of leading scholars from the area of Psychology, established by means of a thorough analysis of 166,880 researchers determined from various bibliometric data sources. For the discipline of Psychology, more than 15018 scientists were examined.

What is D-index approval threshold for Psychology
The D-index threshold for including a researcher to be evaluated is placed at 30 if most of their publications are in the area of Psychology. The acceptance requirements for scientists to be considered into the ranking of top scientists are based on the D-index, ratio of the contributions made within the selected discipline plus the awards and achievements of the scholars. The D-index threshold for including leading scholars is set as an increment of 10 depending on the overall number of researchers assessed for each area od study whilst making sure that the top 1% of best researchers are added into the ranking. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.

Additional verification rules
As our main mission is to make sure that only actual scientists are included in the ranking we realize that numbers are never meant to be a full means to quantify the contributions of scientists. This is why we manually check each profile and cross-correlate it against publications in a wide range of reliable sources. While it’s not a factor defining a researcher’s position in our ranking, the number of documents published in major journals and conference proceedings should form a reliable secondary signal of their contribution to research in a selected area of science. Position in the ranking is established using every researcher’s D-index using data gathered from OpenAlex and CrossRef, which are the most prominent and well-established bibliometric databases of this kind available to the research community. A thorough explanation of our research process can be found on our methodology page.

Our agenda
Our aim is to inspire scholars, entrepreneurs and politicians around the world to explore where top experts are heading and to provide a way for the whole research community to find out who the leading experts in specific areas of study, in different countries, or even within research institutions are.
