Talk by Josh Dever: ‘This Talk Might Change Your Mind’

Based on joint work with Henry Schiller.

Abstract:

Standard probabilistic decision theory models the impact of new information on our preferences for action by having that information shrink our space of doxastically possible worlds and thus alter our probability and value functions. But coupling this model with a semantics of epistemic modals on which epistemic modals never rule out worlds makes it mysterious how certain kinds of modal information, such as “That wine might be poisoned”, could influence our actions. By integrating some semantic ideas from inquisitive semantics with some thoughts from generics on the structure of value functions in probabilistic decision theory, we provide tools that will make sense of the action-influencing nature of such modal information.
