This paper, a reply to the thought-provoking paper The WEIRDest People in the World? (Henrich, Heine & Norenzayan, 2010), makes the fundamental argument that most research paradigms from Western mainstream psychology, including theories, methods, and research procedures, are all very WEIRD once moved to non-Western cultures. We thus face not only biased samples but also a deeply WEIRD psychology. Implanting such a research paradigm into non-Western societies may result in an episteme of self-colonization by formulating a mentality of normative Eurocentrism, which may hinder not only the understanding of a local culture. Through this paper I draw on Kuhn's (1962) Structure of Scientific Revolutions to argue that a crisis is needed to initiate a scientific revolution against WEIRD psychology. I then draw on Hwang's (2019a) epistemological strategy as a path for constructing culture-inclusive theories to compliment Western theories found in mainstream psychology.
