This concluding chapter offers a comprehensive evaluation of Hsu’s paradigm and its significance for constructing a non-Western social science framework. It first confirms that Hsu successfully overcame the methodological limitations of the Culture and Personality School by proposing a coherent theoretical system based on Psychosocial Homeostasis, the Dominant Dyad Hypothesis, and the Secondary Group Hypothesis. These theories together constitute a multilayered model integratingindividual psychology, social structure, and cultural ideals, allowing for comparative studies across literate civilizations. Second, the chapter affirms the cross-civilizational applicability of Hsu’s paradigm, demonstrating its capacity to explain national, ethnic, and political communities in China, the United States, India, and Japan. It traces Hsu’s theoretical expansion from national character studies to ethnic interaction and foreign policy behavior, highlighting his enduring contribution to overcoming Western-centrism. Third, it evaluates the interdisciplinary impact of Hsu’s theories, particularly in psychology,sociology, anthropology, international relations, and ethnic studies. Finally, it introduces the emerging discipline of Psychoculturology, proposed by Shang Huipeng and others, which restructures Hsu’s system around “Basic Interpersonal States.” Psychoculturology is now evolving into a disciplinary complex capable of generating a new cross-cultural paradigm for the social sciences, grounded in Chinese academic traditions and capable of global application.
