In this paper we propose to argue for two claims. The first is that a sizeable group of epistemological projects – a group which includes much of what has been done in epistemology in the analytic tradition – would be seriously undermined if one or more of a cluster of empirical hypotheses about epistemic intuitions turns out to be true. The basis for this claim will be set out in Section 2. The second claim is that, while the jury is (...) still out, there is now a substantial body of evidence suggesting that some of those empirical hypotheses are true. Much of this evidence derives from an ongoing series of experimental studies of epistemic intuitions that we have been conducting. A preliminary report on these studies will be presented in Section 3. In light of these studies, we think it is incumbent on those who pursue the epistemological projects in question to either explain why the truth of the hypotheses does not undermine their projects, or to say why, in light of the evidence we will present, they nonetheless assume that the hypotheses are false. In Section 4, which is devoted to Objections and Replies, we’ll consider some of the ways in which defenders of the projects we are criticizing might reply to our challenge. Our goal, in all of this, is not to offer a conclusive argument demonstrating that the epistemological projects we will be criticizing are untenable. Rather, our aim is to shift the burden of argument. (shrink)

Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational (...) limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance errors are a minor factor in the gap; computational limitations underlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Unexpected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate. Key Words: biases; descriptive models; heuristics; individual differences; normative models; rationality; reasoning. (shrink)

On the surface, it seems intuitively plausible that if an agent luckily manages to perform a desired action (e.g., rolling a six with a fair die or winning the lottery), the performance of which is not the result of any relevant skill on her part, we should not say that she performed the action intentionally. This intuition suggests that our concept of intentional action is sensitive to considerations of skill, luck, and causal control. Indeed, some philosophers have claimed that in (...) order for an action to be performed intentionally it must be performed with a relevant amount of skill or control - i.e., an intentional action cannot simply be the result of luck. On this view, skill and control are necessary conditions of our everyday concept of intentional action. In this essay, I discuss empirical evidence that challenges this claim. After briefly setting the stage, I examine Al Mele and Paul Moser's thorough analysis of intentional action - paying particular attention to some of the interesting scenarios they offer in support of their position. Next, I discuss the results of some simple psychological experiments that show that people's judgments concerning whether actions are intentional can often be affected by the moral features of these actions - features that may trump considerations of skill, luck, and control. Finally, I conclude that if this is correct, philosophers who claim that skill and control are necessary conditions of the folk concept of intentional action appear to be mistaken. One can test attempted philosophical analyses of intentional action partly by ascertaining whether what these analyses entail about particular actions is in line with what the majority of non-specialists would say about these actions if there is a widely shared concept of intentional action, such judgments provide evidence about what the concept is, and a philosophical analysis of intentional action that is wholly unconstrained by that concept runs the risk of having nothing more than a philosophical fiction as its subject matter.

In everyday discourse, we often draw a distinction between actions that are performed intentionally (e.g. opening your car door) and those that are performed unintentionally (e.g. shutting a car door on your finger). This distinction has interested philosophers working in a number of different areas. Indeed, intentional actions are not only the primary focus of those concerned with understanding and explaining human behavior, but they often occupy center stage in philosophical discussions of free will and moral and legal responsibility as (...) well. And while most philosophers agree that the distinction between intentional and unintentional action plays an important role in our folk psychology, there is still wide-scale disagreement about the precise nature of this role. Until recently, there has been a lack of empirical data about the folk concept of intentional action and as a result the debate among philosophers has been mostly. (shrink)

In this paper, I first review some of the recent empirical work on the biasing effect that moral considerations have on folk ascriptions of intentional action. Then, I use Mark Alicke's affective model of blame attribution to explain this biasing effect. Finally, I discuss the relevance of this research - both philosophical and psychological - to the problem of the partiality of jury deliberation. After all, if the immorality of an action does affect folk ascriptions of intentionality, and all serious (...) criminal offenses - e.g., murder and rape - are immoral in addition to being illegal, then a juror's ability to determine the relevant mens rea (i.e., guilty mind) of a defendant in an unbiased way may be seriously undermined.

How are our actions sorted into those that are intentional and those that are not? The philosophical and psychological literature on this topic is livelier now than ever, and we seek to make a contribution to it here. Our guiding question in this article is easy to state and hard to answer: How do various factors— specifically, features of vignettes—that contribute to majority folk judgments that an action is or is not intentional interact in producing the judgment? In pursuing this (...) question we draw on a number of empirical studies, including some of our own, and we sketch some future studies that would shed light on our topic. We emphasize that the factors that concern us here are limited to features of stories to which subject respond: examples include the value of the action asked about, the agent’s being indifferent to performing that action, and the agent’s seeking to perform it. We do not discuss underlying cognitive or emotional processes here, nor do we discuss whether respondents are making errors of any kind. (Both of these issues are discussed in Cushman and Mele [forthcoming].) 1. THREE KINDS OF ACTION In the present section we draw some distinctions that set the stage for our discussion of empirical results. Our actions have effects, and an agent’s bringing about such an effect is itself an action. For example, unbeknownst to Ann, her unlocking the door to her house frightened an intruder. That is, at least one effect of Ann’s unlocking her door was the intruder’s fright. Her bringing about this effect—that is, her frightening the intruder—is an action. Side-effect actions, as we understand this.. (shrink)

In these essays, Hugh J. McCann develops a unified perspective on human action. Written over a period of twenty-five years, the essays provide a comprehensive survey of the major topics in contemporary action theory. In four sections, the book addresses the ontology of action ; the foundations of action ; intention, will, and freedom; and practical rationality. McCann works out a compromise between competing perspectives on the individuation of action ; explores the foundations of action and defends a volitional theory; (...) argues for a libertarian view of both the formation and the execution of intention; and considers the question of consistency in rational intentions, as well as the relationship between practical and theoretical reasoning. -/- Among the original features of McCann's work are his defense of both fine- and coarse-grained actions and his arguments for a noncausal theory of the relation between intention and action. He also suggests that intentions need not be consistent, either with each other or with beliefs about success. And he contends that intention formation is an intrinsically ratiocinative procedure, distinct from reasoning about what action would be best. (shrink)

Recent empirical work calls into question the so-called Simple View that an agent who A’s intentionally intends to A. In experimental studies, ordinary speakers frequently assent to claims that, in certain cases, agents who knowingly behave wrongly intentionally bring about the harm they do; yet the speakers tend to deny that it was the intention of those agents to cause the harm. This paper reports two additional studies that at first appear to support the original ones, but argues that in (...) fact, the evidence of all the studies considered is best understood in terms of the Simple View.

What are the criteria people use when they judge that other people did something intentionally? This question has motivated a large and growing literature both in philosophy and in psychology. It has become a topic of particular concern to the nascent field of experimental philosophy, which uses empirical techniques to understand folk concepts. We present new data that hint at some of the underly- ing psychological complexities of folk ascriptions of intentional action and at dis- tinctions both between diverse concepts (...) and between associated mechanisms.

Recent studies point to a surprising divergence between people's use of the concept of _intention_ and their use of the concept of _acting intentionally_. It seems that people's application of the concept of intention is determined by their beliefs about the agent's psychological states whereas their use of the concept of acting intentionally is determined at least in part by their beliefs about the moral status of the behavior itself (i.e., by their beliefs about whether the behavior is morally good (...) or morally bad). These findings raise a number of difficult questions about the relationship between the concept of intention and the concept of acting intentionally. The present paper addresses those questions using a variety of different methods, including conceptual analysis, psychological experimentation, and an examination of people's use of certain expressions in other languages.

People ordinarily make sense of their own behavior and that of others by invoking concepts like belief, desire, and intention. Philosophers refer to this network of concepts and related principles as 'folk psychology.' The prevailing view of folk psychology among philosophers of mind and psychologists is that it is a proto-scientific theory whose function is to explain and predict behavior.

It is widely believed that the primary function of folk psychology lies in the prediction, explanation and control of behavior. A question arises, however, as to whether folk psychology has also been shaped in fundamental ways by the various other roles it plays in people’s lives. Here I approach that question by considering one particular aspect of folk psychology – the distinction between intentional and unintentional behaviors. The aim is to determine whether this distinction is best understood as a tool (...) used in prediction, explanation and control or whether it has been shaped in fundamental ways by some other aspect of its use. (shrink)

There has been a long-standing dispute in the philosophical literature about the conditions under which a behavior counts as 'intentional.' Much of the debate turns on questions about the use of certain words and phrases in ordinary language. The present paper investigates these questions empirically, using experimental techniques to investigate people's use of the relevant words and phrases. g.

Four experiments examined people’s folk-psychological concept of intentional action. The chief question was whether or not _evaluative _considerations — considerations of good and bad, right and wrong, praise and blame — played any role in that concept. The results indicated that the moral qualities of a behavior strongly influence people’s judgements as to whether or not that behavior should be considered ‘intentional.’ After eliminating a number of alternative explanations, the author concludes that this effect is best explained by the hypothesis (...) that evaluative considerations do play some role in people’s concept of intentional action.<b> </b>.

It is often implied, and sometimes explicitly asserted, that folk psychology is best understood as a kind of predictive device. The key contention of this widely held view is that people apply folk-psychological concepts because the application of these concepts enables them to predict future behavior. If we know what an agent believes, desires, intends, etc., we can make a pretty good guess about what he or she will do next. It seems to me that this picture is not quite (...) right. In a series of recent papers, my colleagues and I have presented data that suggests that moral considerations actually play an important role in folk psychology (Knobe 2003a; 2003b; 2004; Knobe & Burra forthcoming; Knobe & Mendlow forthcoming). These findings do not sit well with the view according to which folk psychology is best understood as a predictive device. It appears that folk psychology might be better understood as a kind of multi-purpose tool. It is used not only in making predictive judgments but also in making moral judgments, and both of these uses appear to have shaped the fundamental competencies that underlie it. One of the most important forms of evidence in this debate comes from studies of the distinction people draw between intentional and unintentional behavior. These studies indicate that people’s intuitions as to whether or not a behavior was performed intentionally can be influenced by their beliefs about the moral status of the behavior.. (shrink)

When time is limited, researchers may be faced with the choice of using an extremely brief measure of the Big-Five personality dimensions or using no measure at all. To meet the need for a very brief measure, 5 and 10-item inventories were developed and evaluated. Although somewhat inferior to standard multi-item instruments, the instruments reached adequate levels in terms of: convergence with widely used Big-Five measures in self, observer, and peer reports, test–retest reliability, patterns of predicted external correlates, and convergence (...) between self and observer ratings. On the basis of these tests, a 10-item measure of the Big-Five dimensions is offered for situations where very short measures are needed, personality is not the primary topic of interest, or researchers can tolerate the somewhat diminished psychometric properties associated with very brief measures.

This book comprises eleven essays in the philosophy of action, six of which were previously published. The book has a fairly extensive index. The essays are arranged in four groups. The first group contains two essays on the individuation of action. The second contains four essays that argue for the view that what makes an event an action is, not how it is caused, but that it is, or begins with, a volition, “an intrinsically actional” mental event. The third contains (...) three essays that defend the view that free and responsible action is incompatible with determinism, largely by arguing for a noncausal account of reasons explanation of action. The final group contains two essays on intention formation and rationality; the first argues that it is sometimes rational to form intentions that are inconsistent with each other or with one’s beliefs; the second argues that an important sort of practical reasoning has as its conclusion the forming of an intention for action, rather than the adopting of a belief as to what one should do.

Humans and animals make inferences about the world under limited time and knowledge. In contrast, many models of rational inference treat the mind as a Laplacean Demon, equipped with unlimited time, knowledge, and computational might. Following H. Simon's notion of satisficing, the authors have proposed a family of algorithms based on a simple psychological mechanism: one-reason decision making. These fast and frugal algorithms violate fundamental tenets of classical rationality: They neither look up nor integrate all information. By computer simulation, the (...) authors held a competition between the satisficing "Take The Best" algorithm and various "rational" inference procedures. The Take The Best algorithm matched or outperformed all competitors in inferential speed and accuracy. This result is an existence proof that cognitive mechanisms capable of successful performance in the real world do not need to satisfy the classical norms of rational inference. (shrink)

Heuristics are efficient cognitive processes that ignore information. In contrast to the widely held view that less processing reduces accuracy, the study of heuristics shows that less information, computation, and time can in fact improve accuracy. We review the major progress made so far: the discovery of less-is-more effects; the study of the ecological rationality of heuristics, which examines in which environments a given strategy succeeds or fails, and why; an advancement from vague labels to computational models of heuristics; the (...) development of a systematic theory of heuristics that identifies their building blocks and the evolved capacities they exploit, and views the cognitive system as relying on an “adaptive toolbox;” and the development of an empirical methodology that accounts for individual differences, conducts competitive tests, and has provided evidence for people’s adaptive use of heuristics. Homo heuristicus has a biased mind and ignores part of the available information, yet a biased mind can handle uncertainty more efficiently and robustly than an unbiased mind relying on more resource-intensive and general-purpose processing strategies.

Our theoretical understanding of individual differences can be used as a tool to test and refine theory. Individual differences are useful because judgments, including philosophically relevant intuitions, are the predictable products of the fit between adaptive psychological mechanisms (e.g., heuristics, traits, skills, capacities) and task constraints. As an illustration of this method and its potential implications, our target article used a canonical, representative, and affectively charged judgment task to reveal a relationship between the heritable personality trait extraversion and some compatabilist (...) judgments. In the current Reply, we further clarify major theoretical implications of these data and outline potential opportunities and obstacles for this methodology. Discussion focuses on (1) the need for theoretically grounded a priori predictions; (2) the use of precise process level data and theory; (3) the possibility of convergent validity as personality is known to predict life experiences and outcomes; and (4) the fundamentally adaptive nature of cognition.

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.

Joshua Knobe (2003a) has discovered that the perceived goodness or badness of side effects of actions influences people's ascriptions of intentionality to those side effects. I present the paradigmatic cases that elicit what has been called the Knobe effect and offer some explanations of the Knobe effect. I put these explanations into two broad groups. One explains the Knobe effect by referring to our concept of intentional action. The other explains the Knobe effect without referring to our concept of intentional (...) action. I discuss some problems with these explanations and conclude with some possible avenues for future research. (shrink)

In a series of five experiments, we demonstrate that moral judgments and folk intuitions are often predictably fragmented. Drawing on the domains of ethics and action theory, we illustrate ways in which judgment tends to be associated with stable individual differences such as personality traits and reflective cognitive styles. We argue that these individual differences pose several unique challenges as well as provide opportunities for further theoretical development in the emerging field of experimental philosophy. Implications are briefly discussed.
