Knowledge Attributions in Context of Decision Problems

In this paper I will show that knowledge attributions that involve embedded questions are context dependent, and that this context dependence involves decision problems, just as the interpretation of standard answers to questions. I will also indicate that knowledge-that sentences are context dependent in a very same way. As a result, so I will argue, the analysis differs from the standard analyses by not just looking at relevant possible worlds. Instead, on this analysis the notion of fine-grainedness plays an important role. I will use the framework of Optimal Assertions, introduced by Benz and developed by Benz & van Rooij to account for optimal interpretations of assertions.
