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
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.
