There is something about Might

In this paper we present an alternative interpretation of statements of epistemic possibility, which does not induce a consistency test on a common ground, as in , but which tests whether the possibility is supported by some update of the common ground, as in . The information space relative to which such claims are evaluated are taken to consist in the possible developements of a discourse in action. It is shown that this notion of Might not only behaves better logically and pragmatically speaking, but that it also allows for non-trivial attitude reports and questions about epistemic possibilities. These epistemic modal statements can also be understood to guide or focus the inquisitive actions of the discourse participants.
