The realization that most behavioral science research focuses on cultures labelled as WEIRD-Western, Educated, Industrialized, Rich and Democratic (Arnett, 2008;Henrich et al., 2010;Thalmayer et al., 2021)-has given an impetus to extend research to more diverse populations. Confucian East Asian societies have relatively strong social and technological infrastructure to advance science, and thus have gained much prominence in cross-cultural studies. This has inadvertently fostered another bias: the dominance of WEIRD-Confucian comparisons, and a tendency to draw conclusions about "non-WEIRD" cultures in general based on data from Confucian societies. Here, analysing 1,466,019 scientific abstracts and, separately, coverage of 60 large-scale cross-cultural psychological projects (Nsamples = 2668 from Ncountries = 153 covering nparticipants = 3 722 940) we quantify the dominance of Confucian over other non-WEIRD cultures in psychological research. Our analysis also reveals the underrepresentation of non-European Union Post-Communist societies and the almost total invisibility of Pacific Island, Caribbean, Middle African, and Central Asian societies within the research database of psychology. We call for a shift in cross-cultural studies towards midsize (7+ countries), and ideally large-scale (50+ countries) cross-cultural studies, and wepropose mitigations that we believe could aid the inclusion of diverse researchers as well as participants from underrepresented cultures in our field. People in all world regions and cultures deserve psychological knowledge that applies to them.
