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.

The compatibility question lies at the center of the free will problem. Compatibilists think that determinism is compatible with moral responsibility and the concomitant notions, while incompatibilists think that it is not. The topic of this paper is a particular form of charge against compatibilism: that it is shallow. This is not the typical sort of argument against compatibilism: most of the debate has attempted to discredit compatibilism completely. The Argument From Shallowness maintains that the compatibilists do have a case. However, this case is only partial, and shallow. This limited aim proves itself more powerful against compatibilists than previous all-or-nothing attempts. It connects to the valid instincts of compatibilists, making room for them, and hence is harder for compatibilists to ignore.

I’ve been told that in the good old days of the 1970s, when Quine’s desert landscapes were regarded as ideal real estate and David Lewis and John Rawls had not yet left a legion of influential students rewriting the terrain of metaphysics and ethics respectively, compatibilism was still compatibilism about free will. And, of course, incompatibilism was still incompatibilism about free will. That is, compatibilism was the view that free will was compatible with determinism. Incompatibilism was the view that free will was incompatible with determinism.1 What philosophers argued about was whether free will was compatible with determinism. Mostly, this was an argument about how to understand claims that one could do otherwise. You needn’t have bothered to talk about moral responsibility, because it was just obvious that you couldn’t have moral responsibility without free will. The literature was a temple of clarity. Then, somehow, things began to go horribly wrong. To be sure, there had been some activity in the 1960s that would have struck some observers as ominous. Still, it was not until the 1980s that those initial warning signs gave way to real trouble. The meanings of terms twisted.

Incompatibilists about free will and responsibility often maintain that incompatibilism is the intuitive, commonsense position. Recently, this claim has come under unfavorable scrutiny from naturalistic philosophers who have surveyed philosophically uneducated undergraduates.1 But there is a much older problem for the claim that incompatibilism is intuitive – if incompatibilism is intuitive, why is compatibilism so popular in the history of philosophy? In this paper I will try to answer this question by pursuing a rather different naturalistic methodology. The idea is to look not at the responses of the philosophically naïve, but at the views of the most sophisticated – the philosophers..

My initial work, with collaborators Stephen Morris, Thomas Nadelhoffer, and Jason Turner (2005, 2006), on surveying folk intuitions about free will and moral responsibility was designed primarily to test a common claim in the philosophical debates: that ordinary people see an obvious conflict between determinism and both free will and moral responsibility, and hence, the burden is on compatibilists to motivate their theory in a way that explains away or overcomes this intuitive support for incompatibilism. The evidence, if any, offered by philosophers to support the claim that incompatibilism is intuitive has consisted of reports of their own intuitions or informal polls of their students. We were skeptical about the reliability of such evidence, so we used the methodology--”now associated with the label 'experimental philosophy'--”of conducting formal surveys on non-philosophers. Our participants read a scenario that describes a deterministic universe and were then asked to judge whether agents in those scenarios act of their own free will and are morally responsible for their actions. Using three different scenarios with hundreds of participants, we consistently found that the majority (2/3 to 4/5) responded that agents in deterministic universes do act of their own free will and are morally responsible. That is, we found that most ordinary folk do not seem to find incompatibilism intuitive or obviously correct. Our results have been challenged in various ways, philosophical and methodological. For instance, Shaun Nichols (2004, this volume) and Nichols and Joshua Knobe (unpublished) offer some experimental evidence suggesting that, in certain conditions, most people express incompatibilist and libertarian intuitions. I will respond to this work in the following section. I agree that people express conflicting intuitions about free will (after all, we consistently found a minority of participants expressing incompatibilist.

Following the recent surge in experimental philosophy exploring how unprimed intuitions enable the folk arrive at judgments concerning free will and moral responsibility, a widespread anomaly in folk intuitions has been reported. This has given rise to two different explanatory frameworks- one counting on affect that has been projected as making all the difference between compatibilism and Incompatibilism and the other relying on Strawsonian participant attitude while accounting for compatibilist responses. The aim of this paper is to bring to the fore the asymmetric folk intuitions regarding ascription of moral responsibility, the expository accounts- one put forward by Shaun Nichols and the other by Eddy Nahmias, and show possibility of reconciliation between the two apparently different views, especially when it comes to unravelling the psychological mechanism underlying compatibilist intuition.

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.

We then present the results of our empirical studies, which put significant pressure on the claim that incompatibilism is intuitive. Next, we consider and respond to potential objections to our approach. We conclude that our data suggest that incompatibilism is not as intuitive as incompatibilists have traditionally assumed, though more work is required to determine what ordinary intuitions about free will and moral responsibility actually are and to understand what role these intuitions should play in the debate.

Recently, there has been an increased interest in folk intuitions about freedom and moral responsibility from both philosophers and psychologists. We aim to extend our understanding of folk intuitions about freedom and moral responsibility using an individual differences approach. Building off previous research suggesting that there are systematic differences in folks’ philosophically relevant intuitions, we present new data indicating that the personality trait extraversion predicts, to a significant extent, those who have compatibilist versus incompatibilist intuitions. We argue that identifying groups of people who have specific and diverse intuitions about freedom and moral responsibility offers the possibility for theoretical advancement in philosophy and psychology, and may in part explain why some perennial philosophical debates have proven intractable.

: In the free will literature, some compatibilists and some incompatibilists claim that their views best capture ordinary intuitions concerning free will and moral responsibility. One goal of researchers working in the fi eld of experimental philosophy has been to probe ordinary intuitions in a controlled and systematic way to help resolve these kinds of intuitional stalemates. We contribute to this debate by presenting new data about folk intuitions concerning freedom and responsibility that correct for some of the shortcomings of previous studies. These studies also illustrate some problems that pertain to all of the studies that have been run thus far.
