การทดสอบข้อสมมติของทฤษฎีเศรษฐศาสตร์เกี่ยวกับความมีเหตุผลของมนุษย์: หลักฐานเชิงประจักษ์จากการทดลองในระบบปิด

This study tests assumptions regarding human rationality, consistency, and decision-making process based on expected value as assumed in expected utility theory. The results from closed experiment using 24 graduate students from faculty of economics as a sample indicate that the majority of samples do not behave as the expected utility theory assumes. Rather, they show preference reversal and do not think in terms of expected value but use intuition. This study suggests that these unrealistic assumptions have to be abandoned and replaced with more realistic ones. Assuming rationality, consistency, and thinking process based on expected value for every decision-making has been proven by other fields of sciences as well as unorthodox economics that these behaviors are not consistent with actual human behaviors.
