Coarse contingencies and ambiguity
研究一个决策者在不完全了解所有可能影响结果的偶然性时，如何基于粗粒度的主观分类做出选择，并意识到遗漏细节可能影响行为。
The paper considers an agent who must choose an action today un-der uncertainty about the consequence of any chosen action but without having in mind a complete list of all the contingencies that could inuence outcomes. She conceives of some relevant (subjective) contingencies but she is aware that these contingencies are coarse- they leave out some details that may a¤ect outcomes. Though she may not be able to describe these ner details, she is aware that they exist and this may a¤ect her behavior.
