Daniel Hoek: "Questions in Action"

Daniel Hoek, PhD Student, New York University: "Questions in Action"

Abstract
Choices confront agents with questions. Lost in a dark forest and coming to a fork in the road, you wonder Which path will get me out of here? The choice of how many eggs to buy at the supermarket raises the question How many eggs go into a spaghetti carbonara for four? And so on: whenever you make a choice, you face a question. In this talk, I outline a systematic account of the role that questions play in decision-making, in the form of a new, inquisitive decision theory.

Inquisitive decision theory can account for many ordinary patterns of behaviour that classical decision theory does not capture. In particular, we can account for the distinction between recognition and recall, and for belief states that are not closed under deduction. The theory builds on a converging set of insights about the role of questions from epistemology and the philosophy of language (Dretske 1970, Schaffer 2004, Blaauw 2012, Friedman 2013, Yablo 2014, Yalcin 2016), semantics (Ciardelli, Groenendijk and Roelofsen 2013), pragmatics (Simons, Beaver, Tonnhauser and Roberts 2017), cognitive science (Koralus and Mascarenhas 2013), decision theory (Elga and Rayo 2016a/b, 2017) and the metaphysics of propositions (Yablo 2014, Fine 2017a/b).
