Interactive Epistemology

项目摘要博弈论中的交互认识论及其在交互环境中的应用，如经济学、国家和国际政治、生态学、计算机科学、法律和社会心理学，重要的是考虑主人公对其他主人公知道和相信的事情的了解和相信。这一研究领域被称为交互认识论。目前的研究集中在两个方面：(1)假设“理性常识”的后果--所有的主人公都是理性的，所有人都知道，都知道这一点，等等；(2)发展一种交互信念的“句法”模型，其中事件用简单的语言描述，而不是更广为人知但不太透明的“语义”模型，在该模型中，事件被描述为“世界状态”的集合。

Project Abstract INTERACTIVE EPISTEMOLOGY In game theory and its applications to interactive contexts like economics, national and international politics, ecology, computer science, law, and social psychology, it is important to consider what the protagonists know and believe about what other protagonists know and believe. This area of research is called `Interactive Epistemology.` The current study concentrates on two aspects: (1) The consequences of assuming `Common Knowledge of Rationality` -- that all protagonists are rational, all know that, all know THAT, and so on; and (2) developing a `syntactic` model of interactive belief, in which events are described in plain language, rather than the better known but less transparent `semantic` model, in which events are characterized as sets of `states of the world.`
