An important disagreement in contemporary debates about free will hinges on whether an agent must have alternative possibilities to be morally responsible. Many assume that notions of alternative possibilities are ubiquitous and reflected in everyday intuitions about moral responsibility: if one lacks alternatives, then one cannot be morally responsible. We explore this issue empirically. In two studies, we find evidence that folk judgments about moral responsibility call into question two popular principles that require some form of alternative possibilities for moral (...) responsibility. Survey participants given scenarios involving agents that fail to satisfy these principles nonetheless found these agents to be morally responsible, blameworthy, deserving of blame, and at fault for morally bad actions and consequences. We defend our interpretation of this evidence against objections and explore some implications of these findings for the free will debate. (shrink)

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. (shrink)

In four experiments, we offer evidence that virtues are often judged as uniquely important for some business practices (e.g., hospital management and medical error investigation). Overall, actions done only from virtue (either by organizations or individuals) were judged to feel better, to be more praiseworthy, to be more morally right, and to be associated with more trustworthy leadership and greater personal life satisfaction compared to actions done only to produce the best consequences or to follow the correct moral rule. These (...) results accord with claims made by some virtue ethicists. The current data contribute to a small but growing body of literature emphasizing both empirical soundness and philosophical rigor in the scientific study of virtue. Results also offer some guidance concerning how businesses, employees, and executives are evaluated and perceived. Implications for theory and practice are discussed. (shrink)

Recent metaphilosophical debates have focused on the methods/epistemology of philosophy, and the structure of the discipline. The paper reports the results of an exploratory study examining the relationship between personality and both kinds of metaphilosophical view. The findings reported are No important link between personality and attitudes to intuitions, Apparent differences between experts and non-experts as to which subfields are considered central, Only limited evidence that perceptions of centrality are related to personality in minor ways. Although no dramatic relationships between (...) personality and metaphilosophical view are found, the results nonetheless prompt some reflection about the role played by judgements about the centrality of subfields within the discipline.

We linked between the social-psychology and experimental-philosophy paradigms for the study of folk intuitions and beliefs regarding the concept of free will to answer three questions: (1) what intuitions do people have about free-will and determinism? (2) do free will beliefs predict differences in free-will and determinism intuitions? and (3) is there more to free-will and determinism than experiencing certainty or uncertainty about the nature of the universe? Overall, laypersons viewed the universe as allowing for human indeterminism, and they did (...) so with certainty. Examining intuitions of prosociality, future-orientation, learning, meaningfulness, human uniqueness, and well-being, ratings were highest in the indeterministic universe condition and lowest in the deterministic universe condition, both significantly different from the uncertain universe condition. Participants’ free will beliefs had only weak impact on realism, happiness, and learning intuitions, but did not reverse the general intuition favoring indeterminism, and showed no impact on other intuitions.

Experimental philosophers have gathered impressive evidence for the surprising conclusion that philosophers' intuitions are out of step with those of the folk. As a result, many argue that philosophers' intuitions are unreliable. Focusing on the Knobe Effect, a leading finding of experimental philosophy, we defend traditional philosophy against this conclusion. Our key premise relies on experiments we conducted which indicate that judgments of the folk elicited under higher quality cognitive or epistemic conditions are more likely to resemble those of the (...) philosopher. We end by showing how our experimental findings can help us better understand the Knobe Effect. (shrink)

Past work has demonstrated that people’s moral judgments can influence their judgments in a number of domains that might seem to involve straightforward matters of fact, including judgments about freedom, causation, the doing/allowing distinction, and intentional action. The present studies explore whether the effect of morality in these four domains can be explained by changes in the relevance of alternative possibilities. More precisely, we propose that moral judgment influences the degree to which people regard certain alternative possibilities as relevant, which (...) in turn impacts intuitions about freedom, causation, doing/allowing, and intentional action. Employing the stimuli used in previous research, Studies 1a, 2a, 3a, and 4a show that the relevance of alternatives is influenced by moral judgments and mediates the impact of morality on non-moral judgments. Studies 1b, 2b, 3b, and 4b then provide direct empirical evidence for the link between the relevance of alternatives and judgments in these four domains by manipulating (rather than measuring) the relevance of alternative possibilities. Lastly, Study 5 demonstrates that the critical mechanism is not whether alternative possibilities are considered, but whether they are regarded as relevant. These studies support a unified framework for understanding the impact of morality across these very different kinds of judgments. (shrink)

This paper provides a comprehensive review of the experimental philosophy of action, focusing on the various different accounts of the Knobe Effect.

Intuitions about intentional action have turned out to be sensitive to normative factors: most people say that an indifferent agent brings about an effect of her action intentionally when it is harmful, but unintentionally when it is beneficial. Joshua Knobe explains this asymmetry, which is known as ‘the Knobe effect’, in terms of the moral valence of the effect, arguing that this explanation generalizes to other asymmetries concerning notions as diverse as deciding and being free. I present an alternative explanation (...) of the Knobe effect in terms of normative reasons. This explanation generalizes to other folk psychological notions such as deciding, but not to such notions as being free. I go on to argue, against Knobe, that offering a unified explanation of all the asymmetries he discusses is in fact undesirable. (shrink)

Empirically minded researchers (e.g., experimental philosophers) have begun exploring the “folk” notion of intentional action, often with surprising results. In this paper, we extend these lines of research and present new evidence from a radically new paradigm in experimental philosophy. Our results suggest that in some circumstances people make strikingly different judgments about intentions and intentionality as a function of whether the person brings about or observes an event. Implications for traditional action theory and the experimental study of folk intuitions (...) are discussed. (shrink)

Many philosophers appeal to intuitions to support some philosophical views. However, there is reason to be concerned about this practice as scientific evidence has documented systematic bias in philosophically relevant intuitions as a function of seemingly irrelevant features (e.g., personality). One popular defense used to insulate philosophers from these concerns holds that philosophical expertise eliminates the influence of these extraneous factors. Here, we test this assumption. We present data suggesting that verifiable philosophical expertise in the free will debate-as measured by (...) a reliable and validated test of expert knowledge-does not eliminate the influence of one important extraneous feature (i.e., the heritable personality trait extraversion) on judgments concerning freedom and moral responsibility. These results suggest that, in at least some important cases, the expertise defense fails. Implications for the practice of philosophy, experimental philosophy, and applied ethics are discussed.

The rise of experimental philosophy has placed metaphilosophical questions, particularly those concerning concepts, at the center of philosophical attention. X-phi offers empirically rigorous methods for identifying conceptual content, but what exactly it contributes towards evaluating conceptual content remains unclear. We show how x-phi complements Rudolf Carnap’s underappreciated methodology for concept determination, explication. This clarifies and extends x-phi’s positive philosophical import, and also exhibits explication’s broad appeal. But there is a potential problem: Carnap’s account of explication was limited to empirical and (...) logical concepts, but many concepts of interest to philosophers are essentially normative. With formal epistemology as a case study, we show how x-phi assisted explication can apply to normative domains. (shrink)

The Knobe effect is the phenomenon demonstrated in the course of repeated studies showing that moral valence affects the way in which we apply concepts. Knobe explains the effect by appealing to the nature of the concepts themselves: whether they actually apply in some situation depends upon the moral valence of some element of that situation. In this paper, a different picture of the effect is presented and given motivation. It is suggested that subjects apply concepts on the basis of (...) substitution inferences. It is attempted to show that this picture is incompatible with, but preferable to, Knobe’s theory. In closing, some further observations and suggestions are given with respect to further research into the apparent effect of moral valence. (shrink)

Experimental philosophers have discovered a large number of asymmetries in our intuitions about philosophically significant notions. Often those intuitions turned out to be sensitive to normative factors. Whereas optimists have insisted on a unified explanation of these findings, pessimists have argued that it is impossible to formulate a single factor explanation. I defend the intermediate position according to which unification is possible to some extent, but should be pursued within limits. The key issue that I address is how it is (...) possible to set such limits in a way that is true to the phenomena. (shrink)

In a celebrated experiment, Joshua Knobe showed that people are much more prone to attribute intentionality to an agent for a side effect of a given act when that side effect is harmful than when it is beneficial. This asymmetry has become known as ‘the Knobe Effect’. According to Knobe's Moral Valence Explanation, bad effects trigger the attributions of intentionality, whereas good effects do not. Many others believe that the Knobe Effect is best explained in terms of the high amount (...) of blame attributed in the harm condition, and the low amount of praise attributed in the help condition. This Blame Hypothesis explains the high number of intentionality attributions in the harm condition in terms of the high degree of blame people ascribe, and the low number of intentionality attributions in the help conditions in terms of the low degree of praise people attribute. We replicated Knobe's original experiment and conducted a logistic regression on the results to probe more deeply into the relationship between attributions of intentionality and responsibility. The statistical analysis revealed a hitherto unknown interaction effect: intentionality correlates with blame, but not with praise. This interaction effect is consistent with the Moral Valence Hypothesis, but inconsistent with the Blame Hypothesis, as well as with two of the three other hypotheses discussed here. (shrink)

ZusammenfassungDem sogenannten Knobe-Effekt zufolge bestimmt die moralische Valenz von Nebeneffekten menschlichen Verhaltens die Zuschreibung ihrer absichtlichen Verursachung. Wir argumentieren, dass erstens die empirisch ermittelten sozialpsychologischen Daten den Knobe-Effekt in der üblichen Lesart nicht belegen, vor allem wegen der unvollständigen Untersuchung der entscheidenden moralischen Varianzfaktoren. Zweitens zeigen wir, dass - und wie - eine spezifische Version des traditionellen Prinzips des Doppeleffekts den empirisch bestätigten Teil des Knobe-Effekts philosophisch erklärt. Die Erklärungskraft des Prinzips des Doppeleffekts kann auch als eine Rechtfertigung eben dieses (...) Prinzips gesehen werden. (shrink)

We propose another positive illusion that fits with McKay & Dennett's (M&D's) criteria for adaptive misbeliefs. This illusion is pervasive in adult reasoning but we focus on its prevalence in children's developing theories. It is a strongly held conviction arising from normal functioning of the doxastic system that confers adaptive advantage on the individual.

It is commonly claimed that fully virtuous individuals cannot be ignorant and that everyday intuitions support this fact. Others maintain that there are virtues of ignorance and most people recognize them. Both views cannot be correct. We report evidence from three experiments suggesting that ignorance does not rule out folk attributions of virtue. Additionally, results show that many of these judgments can be predicted by one’s emotional stability—a heritable personality trait. We argue that these results are philosophically important for the (...) study of virtue and we discuss some of the ways individual differences may inform and facilitate current debates in ethics. We close with a cautionary argument detailing the risks of discounting some intuitions simply because they are associated with seemingly less desirable personality traits. (shrink)

Perhaps personality traits substantially influence one’s philosophically relevant intuitions. This suggestion is not only possible, it is consistent with a growing body of empirical research: Personality traits have been shown to be systematically related to diverse intuitions concerning some fundamental philosophical debates. We argue that this fact, in conjunction with the plausible principle that almost all adequate philosophical views should take into account all available and relevant evidence, calls into question some prominent approaches to traditional philosophical projects. To this end, (...) we present the Philosophical Personality Argument (PPA). We explain how it supports the growing body of evidence challenging some of the uses of intuitions in philosophy, and we defend it from some criticisms of empirically based worries about intuitions in philosophy. We conclude that the current evidence indicates that the PPA is sound, and thus many traditional philosophical projects that use intuitions must become substantially more empirically oriented. (shrink)

We review evidence showing that disagreement in folk and expert philosophical intuitions can be predicted by global, heritable personality traits. The review focuses on recent studies of intuitions about free will, ethics, and intentional action. These findings are philosophically important because they suggest that while some projects cannot be done, other projects must take individual differences in philosophical character into account. But care needs to be taken when interpreting the implications of these individual differences. We illustrate one way that these (...) differences have been abused. We then illustrate two ways that these findings can be legitimately used to help illuminate philosophical issues. Given the large and readily available body of evidence, neglect of persistent and predictable philosophical differences is irresponsible. (shrink)

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.

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. (shrink)

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. (shrink)

Naive physics beliefs can be systematically mistaken. They provide a useful test-bed because they are common, and also because their existence must rely on some adaptive advantage, within a given context. In the second part of the commentary we also ask questions about when a whole family of misbeliefs should be considered together as a single phenomenon.

Objective Altruism is arguably the quintessential moral trait, involving willingness to benefit others and unwillingness to harm them. In this study, I explored how altruism and other personality variables relate to acceptance of euthanasia. In addition, I investigated the role of culture in attitudes to subcategorical distinctions of euthanasia.Methods 190 Iranian students completed the Attitude Towards Euthanasia scale, the HEXACO Personality Inventory-Revised, and an interest in religion measure.Results Higher scores on altruism, Honesty–Humility, Agreeableness, Conscientiousness and religiousness were associated with viewing (...) euthanasia as unacceptable. As expected, altruism explained unique variance in euthanasia attitude beyond gender, religiosity and broad personality factors.Conclusions Cultural and individual differences should be taken into consideration in moral psychology research and end-of-life decision-making.

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.

Philosophy has recently been presented with, and started to take seriously, sociological studies in which our ‘folk concepts’ are elaborated. The most interesting concepts studied are moral concepts, and results have been achieved that seem to sharply contradict the speculation of philosophers and to threaten the very way in which moral philosophy has been done in the past. In this paper, I consider certain results in empirical studies of the folk concept of responsibility. I will then sketch a version of (...) a reactive attitude theory that allows for a genuine sense in which our intuitions about responsibility may be incoherent in a certain sense but without making moral reasoning radically contextual.

Research has consistently shown that people consider harmful side effects of an action more intentional than helpful side effects. This phenomenon is known as the side- effect effect (SEE), which refers to the influence of moral considerations in judgments of intentionality and other non-moral concepts. There is an ongoing debate about how to explain this asymmetric pattern of judgment and the psychological factors involved in it. It has been posited that affective reactions to agents that bring about harmful side- effects (...) could bias intentionality attributions in these cases, explaining the asymmetric pattern of intentionality judgments that we observe in the SEE. We call this the affective bias hypothesis (ABH). Evidence for the ABH is mixed, with some findings suggesting a role for affective processes, while others suggesting that affective processes play no role in the SEE. A possible explanation for these apparently contradictory results points to affective processes involved in the SEE being confined to anger. In a series of empirical studies, we systematically measured and manipulated participants’ anger in order to test this possibility. Our findings suggest that anger play no role in intentionality judgments in SEE cases, while providing support for a non-emotional motivation to blame as a factor underlying the SEE. (shrink)
