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. (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.

We explore and provide an account for a recently identified judgment anomaly, i.e., an order effect that changes the strength of intentionality ascriptions for some side effects (e.g., when a chairman's pursuit of profits has the foreseen but unintended consequence of harming the environment). Experiment 1 replicated the previously unanticipated order effect anomaly controlling for general individual differences. Experiment 2 revealed that the order effect was multiply determined and influenced by factors such as beliefs (i.e., that the same actor was (...) involved in bringing about both good and bad side effects) and philosophical training (i.e., more training was associated with smaller differences in judgment when harm followed help). Results provide more evidence that the folk's philosophically relevant intuitions are predictably fragmented and depend on the dynamic interplay between persons, process, and environments. Methodological and theoretical implications are discussed. (shrink)

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.

Heritable personality traits often predict fundamental philosophical disagreement. This conclusion is based on studies of more than 15,000 people sampled from diverse cultures and educational backgrounds, including verifiable experts. In this chapter, we review some of this research showing links between personality and philosophical bias in free will, intentional action, and ethics. Our discussion focuses on serious challenges that these philosophical biases pose (e.g., limits on the use of philosophical intuitions as evidence). We close with discussion of the Philosophical Personality (...) Argument and brief consideration of emerging projects in applied experimental philosophy. (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.

Although it makes some progress, McKay & Dennett's (M&D's) proposal is limited because (1) the argument for adaptive misbelief is not new, (2) arguments overextend the evidence provided, and (3) the alleged sufficient conditions are not as prohibitive as suggested. We offer alternative perspectives and evidence, including individual differences research, indicating that adaptive misbeliefs are likely much more widespread than implied.

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.

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 field 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. (shrink)

Visual aids can improve comprehension of risks associated with medical treatments, screenings, and lifestyles. Do visual aids also help decision makers accurately assess their risk comprehension? That is, do visual aids help them become well calibrated? To address these questions, we investigated the benefits of visual aids displaying numerical information and measured accuracy of self-assessment of diagnostic inferences (i.e., metacognitive judgment calibration) controlling for individual differences in numeracy. Participants included 108 patients who made diagnostic inferences about three medical tests on (...) the basis of information about the sensitivity and false-positive rate of the tests and disease prevalence. Half of the patients received the information in numbers without a visual aid, while the other half received numbers along with a grid representing the numerical information. In the numerical condition, many patients --especially those with low numeracy-- misinterpreted the predictive value of the tests and profoundly overestimated the accuracy of their inferences. Metacognitive judgment calibration mediated the relationship between numeracy and accuracy of diagnostic inferences. In contrast, in the visual aid condition, patients at all levels of numeracy showed high-levels of inferential accuracy and metacognitive judgment calibration. Results indicate that accurate metacognitive assessment may explain the beneficial effects of visual aids and numeracy --a result that accords with theory suggesting that metacognition is an essential part of risk literacy. We conclude that well-designed risk communications can inform patients about health-relevant numerical information while helping them assess the quality of their own risk comprehension. (shrink)

The past ten years have seen multiple attempts to estimate the relation between the global personality trait extraversion and compatibilist free will judgments. Here, we contribute to that line of research by conducting a meta-analysis of 17 published and eight unpublished studies (N = 2,811) estimating that relation. Overall, the mean effect size was modest but remarkably robust across materials, locations, and labs (z =.19, 95% CI.15-.24, p <.001). No significant publication bias was detected in the studies (t (23) = (...) 1.88, p =.07). While there was no significant heterogeneity in the studies (Q (24) = 34.42, p =.08, I2 = 26.05), a moderator analysis suggested that the effect is strongest in cases that contain highly affective actions (e.g., murder) (z =.22, 95% CI.17-.28, p <.001) and weakest in cases that contain actions with low affect (e.g., asking whether free will is compatible with determinism) (z =.09, 95% CI -.05-.23, p =.22). The meta-analysis provides additional evidence that extraversion is related to compatibilist free will judgments and helps to identify opportunities to discover boundary conditions and more proximal causal mechanisms for the relation. The results of the meta-analysis also have implications for informed decision making. (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)

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)

Evaluational internalism holds that only features internal to agency (e.g., motivation) are relevant to attributions of virtue [Slote, M. (2001). Morals from motives. Oxford: Oxford University Press]. Evaluational externalism holds that only features external to agency (e.g., consequences) are relevant to attributions of virtue [Driver, J. (2001). Uneasy virtue. Cambridge: Cambridge University Press]. Many evaluational externalists and internalists claim that their view best accords with philosophically naïve (i.e., folk) intuitions, and that accordance provides argumentative support for their view. Evaluational internalism (...) and externalism are incompatible views and therefore it is impossible that both views are supported by most folk intuitions. In four experiments, we present evidence that neither pure evaluational internalism nor pure evaluational externalism accurately capture some relevant folk intuitions about virtue. However, our experiments suggest external factors are vastly more important than internal factors for folk attributions of virtue. While these data do not entail that evaluational internalism and externalism about virtue are false, they situate important argumentative burdens, constrain philosophical theory about virtue, and illustrate a valuable method that could foster more efficient progress in ethics.

Oaksford & Chater (O&C) focus on patterns of typical adult reasoning from a probabilistic perspective. We discuss implications of extending the probabilistic approach to lifespan development, considering the role of working memory, strategy use, and expertise. Explaining variations in human reasoning poses a challenge to Bayesian rational analysis, as it requires integrating knowledge about cognitive processes.

Some theorists argue that appropriate responses to terrorism are in part shaped by popular sentiment. In two experiments, using representative design and ecological stimuli (e.g. actual news reports), we present evidence for some of the ways popular sentiment about terrorism tracks theory and can be constructed. In Experiment 1, we document that using the word ‘terrorist’ to describe a group of people decreases willingness to understand the group's grievances, decreases willingness to negotiate with the group, increases perceived permissibility of violence (...) against the group, and decreases the perceived rationality of the group. In Experiment 2, we demonstrate that judgment about the permissibility of the use of force against terrorist groups can be biased by simple memory-priming manipulations. Results are interpreted in terms of (1) implications for philosophical theories about terrorism and (2) the role that experimental investigation can play in applied ethics. (shrink)

Throughout his early career, Sir Edward Coke joined many of his contemporaries in his concern about the uncertainty of the common law. Coke attributed this uncertainty to the ignorance and entrepreneurship of practitioners, litigants, and other users of legal power whose actions eroded confidence in the law. Working to limit their behaviours, Coke also simultaneously sought to strengthen royal authority and the Reformation settlement. Yet the tensions in his thought led him into conflict with James I, who had accepted (...) many of the criticisms of the common law. Sir Edward Coke and the Reformation of the Laws reframes the origins of Coke's legal thought within the context of law reform and provides a new interpretation of his early career, the development of his legal thought, and the path from royalism to opposition in the turbulent decades leading up to the English civil wars.

In this paper, we examine Adam Feltz and Edward Cokely’s recent claim that “the personality trait extraversion predicts people’s intuitions about the relationship of determinism to free will and moral responsibility”. We will first present some criticisms of their work before briefly examining the results of a recent study of our own. We argue that while Feltz and Cokely have their finger on the pulse of an interesting and important issue, they have not established a robust and (...) stable connection between extraversion and compatibilist-friendly intuitions.

All entries and substantive updates are refereed by the members of a distinguished Editorial Board before they (...) are made public. (shrink)

How can I give you a reason to believe what I tell you? I can influence the evidence available to you. Or I can simply invite your trust. These two ways of giving reasons work very differently. When a speaker tells her hearer that p, I argue, she intends that he gain access to a prima facie reason to believe that p that derives not from evidence but from his mere understanding of her act. Unlike mere assertions, acts of telling (...) give reasons directly. They give reasons by inviting the hearer’s trust. This yields a novel form of anti-reductionism in the epistemology of testimony. The status of testimony as a sui generis source of epistemic warrant is entailed by the nature of the act of telling. We can discover the nature of this illocution, and its epistemic role, by examining how it functions in the real world of human relations. (shrink)

[The version of this paper published by Oxford online in 2019 was not copy-edited and has some sense-obscuring typos. I have posted a corrected (but not the final published) version on this site. The version published in print in 2020 has these corrections.] Which is more fundamental, assertion or testimony? Should we understand assertion as basic, treating testimony as what you get when you add an interpersonal addressee? Or should we understand testimony as basic, treating mere assertion -- assertion without (...) testimony -- as what you get when you subtract that interpersonal relation? In this chapter, I’ll argue for the subtractive approach and for the more general thesis that its treatment of the interpersonal element in assertion makes understanding that interpersonal element the key to understanding how assertion expresses belief. My theory of belief-expression in assertion treats it as internalizing the transmission of belief in testimony. How we understand that internalizing move depends on how we conceptualize the interpersonal element in testimony. Since what I’ll call the Command Model does not give us the conceptual resources to make this move, we should adopt an alternative that I’ll call the Custodial Model, on which a testifier aims not to convince her addressee but to reason with him – to give him reasons to believe what she tells him grounded in her trustworthiness in thus attempting to influence him. The subtractive approach to assertion thus rests on a key distinction between the aims of reasoning and persuasion. (shrink)

An assurance theory of trust begins from the act of assurance – whether testimonial, advisorial or promissory – and explains trust as a cognate stance of resting assured. My version emphasizes the risks and rewards of trust. On trust’s rewards, I show how an assurance can give a reason to the addressee through a twofold exercise of ‘normative powers’: (i) the speaker thereby incurs an obligation to be sincere; (ii) if the speaker is trustworthy, she thereby gives her addressee the (...) reason. Each claim is controversial; my contribution lies in how I defend them together, linking the sincerity obligation to the provision of reasons. On trust’s risks, I defend a popular thesis about the nature of trust – that trust differs from mere reliance in how it risks betrayal – against the objection that the thesis ‘moralizes’ trust. Such betrayal need not be moral, I argue, because it may derive entirely from how the assurance purports to provide a reason. (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)

The biggest obstacle to understanding Aquinas's account of the soul may be the word “soul”. On hearing it, many people are prone to think of ghosts, ectoplasm, or Rene Descartes's notion of res cogitans. None of these has anything to do with the soul as Aquinas understands it. But even the standard one‐line Aristotelian‐Thomistic characterization of the soul as the form of the living body can too easily mislead. As is well known, the word “soul” is in Aristotelian‐Thomistic philosophy essentially (...) a technical term for the substantial form of a living thing. Material substances can be destroyed by other natural objects because they do have an inherent tendency toward corruption. A human being is the kind of substance which, in its mature and normal state, exhibits both the properties and causal powers characteristic of animality and those characteristic of rationality.

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)

This book has implications for anyone interested in comparative religion, early China, cultural studies, digital humanities, or science-humanities (...) integration. (shrink)

The first is to situate Sartre's metaphysical views in relation to those of his predecessors, his contemporaries, and current continental philosophy.

The third is to bring Sartre the metaphysician into dialogue with key thinkers in the current realism/antirealism debate in Continental philosophy by showing that (...) the defense of materialism he offers in his later work preserves many hard-won insights of phenomenology and has significant advantages over many contemporary articulations of realism.

Western scholarship on early Chinese thought has tended to either dismiss the foundational role of metaphor or to see it as a uniquely Chinese mode of apprehending the world. This article argues that, while human cognition is in fact profoundly dependent on imagistic conceptual structures, such dependence is by no means a unique feature of Chinese thought. The article reviews empirical evidence supporting the claims that human thought is fundamentally imagistic; that sensorimotor schemas are often used to structure our understanding (...) of abstract concepts; that these schemas can be selectively combined to result in novel structures; and that there are inextricable connections between body, emotion, and thought in both everyday and philosophical cognition. It also provides a review of a recent trend where, explicitly or not, scholars from a variety of backgrounds have begun to take metaphor more seriously as a foundational bearer of philosophical meaning in early China.

Der Verfasser legt einen Kommentar vor, der allen Lesern von Humes erkenntnistheoretischen Schriften hilfreich sein wird; auch werden zentrale Aspekte seiner Moral- und Religionsphilosophie vorgefuhrt und diskutiert. Dabei wird ein Gesamtbild der Philosophie Humes entwickelt und in den Zusammenhang des zeitgenossischen europaischen Denkens gestellt. Hier bekampft der Verfasser die gelaufige Interpretation, derzufolge Hume als der konsequente Zerstorer des Empirismus gilt; Humes Ziel sei eher die Widerlegung einer Weltauffassung, die fast allen Philosophen seiner Epoche, Empiristen und Rationalisten, gemeinsam war. In einem (...) Anhang wird sein Verhaltnis zur kritischen Philosophie Kants eingehender behandelt. Auf diese Weise soll nicht nur Studenten eine Einfuhrung in die Philosophie Humes, sondern auch Spezialisten grundsatzlich neues Material geboten werden. (shrink)
