基于偏好的无意识
Preference-Based Unawareness
摘要:
Morris(1996,1997)在标准状态空间结构中引入了基于偏好的知识和信念定义。本文将这种基于偏好的方法扩展到无意识结构(Heifetz,Meier和Schipper,2006,2008)。通过定义无意识和知识的偏好在无意识结构的行为,并显示其等价的无意识和知识的认知概念,我们试图建立一个决策理论和认知逻辑之间的桥梁。对事件的不觉察在行为上表现为事件为空及其否定为空。
英文摘要:
Morris (1996, 1997) introduced preference-based definitions of knowledge and belief in standard state-space structures. This paper extends this preference-based approach to unawareness structures (Heifetz, Meier, and Schipper, 2006, 2008). By defining unawareness and knowledge in terms of preferences over acts in unawareness structures and showing their equivalence to the epistemic notions of unawareness and knowledge, we try to build a bridge between decision theory and epistemic logic. Unawareness of an event is characterized behaviorally as the event being null and its negation being null.
