Reverse Bayesianism: A Comment
评论了Karni和Vierø（2013）关于新行动和后果下决策的理论，指出当引入新后果时，即使外部观察者能唯一确定决策者对后果的序数排序，可行行动上的任意偏好反转仍被允许。
Karni and Vierø (2013) present an interesting theory of decisions in the presence of new actions and consequences. We establish results on the observable implications of the model. When introducing new consequences, arbitrary preference reversals over feasible actions are permitted. This occurs even if an outside observer can uniquely pin down the decision maker's ordinal ranking over consequences.
