Philosophers working in the nascent field of 'experimental philosophy' have begun using methods borrowed from psychology to collect data about folk intuitions concerning debates ranging from action theory to ethics to epistemology. In this paper we present the results of our attempts to apply this approach to the free will debate, in which philosophers on opposing sides claim that their view best accounts for and accords with folk intuitions. After discussing the motivation for such research, we describe our methodology of surveying people's prephilosophical judgments about the freedom and responsibility of agents in deterministic scenarios. In two studies, we found that a majority of participants judged that such agents act of their own free will and are morally responsible for their actions. We then discuss the philosophical implications of our results as well as various difficulties inherent in such research.

Experimental philosophy is a new movement that seeks to return the discipline of philosophy to a focus on questions about how people actually think and feel. Departing from a long-standing tradition, experimental philosophers go out and conduct systematic experiments to reach a better understanding of people’s ordinary intuitions about philosophically significant questions. Although the movement is only a few years old, it has already sparked an explosion of new research, challenging a number of cherished assumptions in both philosophy and cognitive science. The present volume provides an introduction to the major themes of work in experimental philosophy, bringing together some of the most influential articles in the field along with a collection of new papers that explore the theoretical significance of this new research.

Experimental examination of how the folk conceptualize certain philosophically loaded notions can provide information useful for philosophical theorizing. In this paper, we explore issues raised in Shaun Nichols’ (2004) studies involving people’s conception of free will, focusing on his claim that this conception fits best with the philosophical theory of agent-causation. We argue that his data do not support this conclusion, highlighting along the way certain considerations that ought to be taken into account when probing the folk conception of free will.

Incompatibilists believe free will is impossible if determinism is true, and they often claim that this view is supported by ordinary intuitions. We challenge the claim that incompatibilism is intuitive to most laypersons and discuss the significance of this challenge to the free will debate. After explaining why incompatibilists should want their view to accord with pretheoretical intuitions, we suggest that determining whether incompatibilism is in fact intuitive calls for empirical testing. We then present the results of our studies, which put significant pressure on the claim that incompatibilism is intuitive. Finally, we consider and respond to several potential objections to our approach.
