Fundamental beliefs about free will and moral responsibility are often thought to shape our ability to have healthy relationships with others and ourselves. Emotional reactions have also been shown to have an important and pervasive impact on judgments and behaviors. Recent research suggests that emotional reactions play a prominent role in judgments about free will, influencing judgments about determinism’s relation to free will and moral responsibility. However, the extent to which affect influences these judgments is unclear. We conducted a metaanalysis to estimate the impact of affect. Our meta-analysis indicates that beliefs in free will are largely robust to emotional reactions.

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.

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.

George Bealer argues that intuitions are not only reliable indicators of truth, they are necessary to the philosophical endeavor. Specifically, he thinks that intuitions are essential sources of evidence for epistemic justification. I argue that Bealer's defense of intuitions either (1) is insufficient to show that actual human beings are in a position to use intuitions for epistemic justification, or (2) begs the question. The growing empirical data about our intuitions support the view that humans are not creatures appropriately positioned to use intuitions for epistemic justification in the way Bealer suggests. Without the appropriate empirical evidence that humans are beings so positioned, his view begs the question against those who think that intuitions are not reliable guides to truth.

Surrogates’ decisions to withhold or withdraw life-sustaining treatments (LSTs) are pervasive. However, the factors influencing surrogates’ decisions to initiate LSTs are relatively unknown. We present evidence from two experiments indicating that some surrogates’ decisions about when to initiate LSTs can be predictably manipulated. Factors that influence surrogate decisions about LSTs include the patient’s cognitive state, the patient’s age, the percentage of doctors not recommending the initiation of LSTs, the percentage of patients in similar situations not wanting LSTs, and default treatment settings. These results suggest that some people may use heuristics when making these important life-and-death decisions. These findings may have important moral implications for improving surrogate decisions about LSTs and reconsidering paternalism

According to intellectualism, what a person knows is solely a function of the evidential features of the person's situation. Anti-intellectualism is the view that what a person knows is more than simply a function of the evidential features of the person's situation. Jason Stanley (2005) argues that, in addition to “traditional factors,” our ordinary practice of knowledge ascription is sensitive to the practical facts of a subject's situation. In this paper, we investigate this question empirically. Our results indicate that Stanley's assumptions about knowledge ascriptions do not reflect our ordinary practices in some paradigmatic cases. If our data generalize, then arguments for anti-intellectualism that rely on ordinary knowledge ascriptions fail: the case for anti-intellectualism cannot depend on our ordinary practices of knowledge ascription.

When the side effect of an action involves moral considerations (e.g. when a chairman’s pursuit of profits harms the environment) it tends to influence theory-of-mind judgments. On average, bad side effects are judged intentional whereas good side effects are judged unintentional. In a series of two experiments, we examined the largely uninvestigated roles of individual differences in this judgment asymmetry. Experiment 1 indicated that extraversion accounted for variations in intentionality judgments, controlling for a range of other general individual differences (e.g. working memory, self-control). Experiment 2 indicated that extraversion’s influence was partially mediated by more specific variations in intentional action concepts. A priming manipulation also provided causal evidence of judgment instability and bias. Results suggest that the intentional action judgment asymmetry is multiply determined, reflecting the interplay of individual differences and judgment biases. Implications and the roles of individual differences in judgment and decision-making research are discussed.

A large portion of philosophy done in the Western analytic tradition attempts to provide conceptual analyses which are tested by examples that elicit intuitions. These intuitions are, in turn, used as evidence either for or against a given analysis. In recent years, there has been much discussion of the uses of intuitions from empirically minded philosophers and psychologists. The basic strategy is to discover empirically how “normal” folks think about certain topics in philosophy. This application of folk intuitions to philosophy branches into roughly two basic approaches. The first is an attempt to show that in given domains, folk intuitions are not very reliable sources of evidence; hence, we have good reason to think that philosophers' intuitions are also not reliable sources of evidence in that domain. The second approach attempts to determine what folk concepts are. Once folk concepts are analyzed, they are then argued to be relevant to philosophical debates. My guiding question for this dissertation is the following one: Why should philosophers care about folk intuitions? One answer is that we should want some philosophical analyses to be grounded in everyday concepts. I argue that there are presently no adequate a priori arguments for the reliability of philosophical intuitions in some philosophically relevant areas. Whether intuitions are reliable enough to ground philosophical analyses is an empirical question. I review four domains where ordinary concepts have been argued to ground philosophical theorizing: (1) epistemology, (2) ethics, (3) free will, and (4) action theory. I argue that the available evidence suggests that we should be skeptical of intuitions in philosophy—but that skepticism does not entail radical skepticism. That is, the empirical studies reveal a wide variety of results which on the surface indicate that intuitions are not reliable (e.g., order effects or framing effects). However, I argue that these seeming instabilities are actually the results of stable differences in different groups of people. Hence, I argue that intuitions are stable in a surprising way—that different groups of people have stable intuitions. This intuition stability, while not the kind of monolithic stability many philosophers might desire, is argued to be sufficient to ground philosophical analyses in these domains.

Sommers (2010) argues that experimental philosophers of free will have largely been asking the wrong question – the question whether philosophically naïve individuals think that free will and moral responsibility are compatible with determinism. The present studies begin to alleviate this concern by testing the intuitive plausibility of Pereboom’s (2001) four case argument. The general pattern of responses from two experiments does not support Pereboom’s predictions. Moreover, those who were high in the personality trait emotional stability tended to judge that manipulated agents were more free and morally responsible compared to individuals low in emotional stability.

Experimental philosophy is a new approach to philosophy that incorporates the experimental methodologies of psychology, behavioral economics, and sociology. Experimental philosophers generally maintain that, in addition to traditional philosophical practices, these ways of gathering evidence can be instrumental in shedding light on philosophically important issues. Rather than relying on their own intuitions about specific cases, experimental philosophers perform systematic experiments to determine what intuitions people have about those cases. These intuitions are then used as evidence. In this context, four main approaches to experimental philosophy are introduced, a sample of experimental philosophy’s results is offered, and some of the philosophical importance of those results is explained

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.

Many philosophers have worried about what philosophy is. Often they have looked for answers by considering what it is that philosophers do. Given the diversity of topics and methods found in philosophy, however, we propose a different approach. In this article we consider the philosophical temperament, asking an alternative question: what are philosophers like? Our answer is that one important aspect of the philosophical temperament is that philosophers are especially reflective: they are less likely than their peers to embrace what seems obvious without questioning it. This claim is supported by a study of more than 4,000 philosophers and non-philosophers, the results of which indicate that even when we control for overall education level, philosophers tend to be significantly more reflective than their peers. We then illustrate this tendency by considering what we know about the philosophizing of a few prominent philosophers. Recognizing this aspect of the philosophical temperament, it is natural to wonder how philosophers came to be this way: does philosophical training teach reflectivity or do more reflective people tend to gravitate to philosophy? We consider the limitations of our data with respect to this question and suggest that a longitudinal study be conducted

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.

Thomas Nadelhoffer claims that a morally praiseworthy agent cannot knowingly produce a morally positive side effect. I claim that the argument Nadelhoffer uses to establish this claim has two false premises. The two false premises are: If something is a side effect, then it is not desired or intended; and If agent S is morally praiseworthy and knows that her performing p will produce a morally positive q, then q forms part of S's reason for p-ing. I offer a counterexample that shows the falsity of and . 2012 APA, all rights reserved)

This chapter provides empirical evidence about everyday attitudes concerning euthanasia. These attitudes have important implications for some ethical arguments about euthanasia. Two experiments suggested that some different descriptions of euthanasia have modest effects on people’s moral permissibility judgments regarding euthanasia. Experiment 1 (N = 422) used two different types of materials (scenarios and scales) and found that describing euthanasia differently (‘euthanasia’, ‘aid in dying’, and ‘physician assisted suicide’) had modest effects (≈3 % of the total variance) on permissibility judgments. These effects were largely replicated in Experiment 2 (N = 409). However, in Experiment 2, judgments about euthanasia’s moral permissibility were best predicted by the voluntariness of the treatment. Voluntariness was a stronger predictor than some demographic factors and some domain general elements of moral judgments. These results help inform some debates about the moral permissibility of euthanasia (e.g., the slippery slope argument) suggesting that some of the key premises of those arguments are unwarranted.

Understanding the folk notion of free will and moral responsibility is important for a host of applied and theoretical issues in psychology, philosophy, and ethics. The bulk of experimental research has focused on folk intuitions concerning determinism's relation to free will and moral responsibility. However, determinism is a difficult term for many folk to understand. Accordingly researchers often use comprehension questions to identify and exclude large proportions of participants who seem to struggle with relevant concepts. Here, we document some of the cognitive mechanisms involved in folk judgments related to comprehension of determinism, and its relations to free will and moral responsibility. Results provide prescriptions for experimental designs that can increase comprehension, potentially decreasing sampling biases. Theoretical and methodological implications are discussed.
