This paper reflects on the notion of partial ambiguity. Using a framework decomposing ambiguity into distinct layers of analysis, among which are risk and model uncertainty, and allowing for different attitudes toward these layers, I show that partial ambiguity may prove less desirable than full ambiguity, even under ambiguity aversion. This observation poses difficulties for interpreting the notion of partial ambiguity in relation to the partial information available to determine the potential compositions of an ambiguous urn. Two Ellsberg-style thought experiments are described to challenge the meaning of partial ambiguity further, and an alternative interpretation, based on a more ambiguous relation, is discussed.

本文对部分歧义的概念进行了反思。使用一个框架将歧义分解为不同的分析层次，其中包括风险和模型不确定性，并允许对这些层次采取不同的态度，我证明即使在歧义厌恶之下，部分歧义也可能不如完全歧义更可取。这种观察给解释与部分信息有关的部分歧义的概念带来困难，部分信息可用于确定模棱两可的骨灰盒的潜在成分。描述了两个Ellsberg风格的思想实验，以进一步挑战部分歧义​​的含义，并讨论了一种基于更模糊关系的替代解释。
