贝叶斯决策理论是经典基础性决策理论，该理论要求决策主体按照规范性决策模型并根据期望效用最大化原则作出决策。然而，该理论在实际运用中却面临着共同结果效应、信念度函数的不稳定性、偏好逆转现象、“结构”影响等与实际选择行为相悖的认知困境。从认知角度修正和发展该理论具有重要的理论和实践意义。

英语语境:

According to Bayesian decision theory, one should follow the standardized decision model and the principle of Expected Utility Maximization to make decisions. However, the theory is confronted with the cognitive predicament in practice because of some inconsistencies between the theory and the real decision behavior. It's of important theoretical and practical significance to modify and develop the theory from the angle of cognition. It should be the next research direction to make some effective combination between the logical and psychological process.
