The 2nd edition of Research.com 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
Research.com’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.
