Arguments attempting to debunk moral beliefs, by showing they are unjustified, have tended to be global, targeting all moral beliefs or a large set of them. Popular debunking arguments point to various factors purportedly influencing moral beliefs, from evolutionary pressures, to automatic and emotionally-driven processes, to framing effects. We show that these sweeping arguments face a debunker’s dilemma: either the relevant factor is not a main basis for belief or it does not render the relevant beliefs unjustified. Empirical debunking arguments (...) in ethics can avoid this predicament, but only if they are refocused on highly selective classes of moral belief. Experimental data can combine with familiar consistency reasoning to reveal that like cases are not being treated alike. Selective debunking arguments are unlikely to yield sweeping sceptical conclusions, but they can lead to rational moral change. (shrink)

I argue that moral judgement is a natural kind on the grounds that it plays a causal/explanatory role in psychological generalizations. I then develop an empirically grounded theory of its identity as a natural kind. I argue that moral judgement is a hybrid state of moral belief and moral emotion. This hybrid theory supports the role of moral judgement in explanations of reasoning and action and also supports its role in a dual process model of moral cognition. Although it is (...) composed of moral belief and moral emotion, moral judgement is unified, like other natural kinds, in virtue of underlying mechanisms that generate homeostasis among its components. Finally, this theory about the unity of moral judgement resolves a longstanding puzzle about moral motivation. The view explains how it is that moral judgements motivate all on their own but not all the time. (shrink)

In the last fifteen years, there has been significant interest in studying the brain structures involved in moral judgments using novel techniques from neuroscience such as functional magnetic resonance imaging. Many people, including a number of philosophers, believe that results from neuroscience have the potential to settle seemingly intractable debates concerning the nature, practice, and reliability of moral judgments. This has led to a flurry of scientific and philosophical activities, resulting in the rapid growth of the new field of moral (...) neuroscience. There is now a vast array of ongoing scientific research devoted towards understanding the neural correlates of moral judgments, accompanied by a large philosophical literature aimed at interpreting and examining the methodology and the results of this research. This is the first volume to take stock of fifteen years of research of this fast-growing field of moral neuroscience and to recommend future directions for research. It features the most up-to-date research in this area, and it presents a wide variety of perspectives on this topic. (shrink)

Do psychopaths make moral judgments but lack motivation? Or are psychopaths’ judgments are not genuinely moral? Both sides of this debate seem to assume either externalist or internalist criteria for the presence of moral judgment. However, if moral judgment is a natural kind, we can arrive at a theory-neutral criterion for moral judgment. A leading naturalistic criterion suggests that psychopaths have an impaired capacity for moral judgment; the capacity is neither fully present nor fully absent. Psychopaths are therefore not counterexamples (...) to internalism. Nonetheless, internalism is empirically problematic because it is unable to explain psychopaths’ moral deficits. (shrink)

The recent, influential Social Intuitionist Model of moral judgment (Haidt, Psychological Review 108, 814–834, 2001) proposes a primary role for fast, automatic and affectively charged moral intuitions in the formation of moral judgments. Haidt’s research challenges our normative conception of ourselves as agents capable of grasping and responding to reasons. We argue that there can be no ‘real’ moral judgments in the absence of a capacity for reflective shaping and endorsement of moral judgments. However, we suggest that the empirical literature (...) indicates a complex interplay between automatic and deliberative mental processes in moral judgment formation, with the latter constraining the expression and influence of moral intuitions. We therefore conclude that the psychological literature supports a normative conception of agency. (shrink)

According to rationalism regarding the psychology of moral judgment, people’s moral judgments are generally the result of a process of reasoning that relies on moral principles or rules. By contrast, intuitionist models of moral judgment hold that people generally come to have moral judgments about particular cases on the basis of gut-level, emotion-driven intuition, and do so without reliance on reasoning and hence without reliance on moral principles. In recent years the intuitionist model has been forcefully defended by Jonathan Haidt. (...) One important implication of Haidt’s model is that in giving reasons for their moral judgments people tend to confabulate – the reasons they give in attempting to explain their moral judgments are not really operative in producing those judgments. Moral reason-giving on Haidt’s view is generally a matter of post hoc confabulation. Against Haidt, we argue for a version of rationalism that we call ‘morphological rationalism.’ We label our version ‘morphological’ because according to it, the information contained in moral principles is embodied in the standing structure of a typical individual’s cognitive system, and this morphologically embodied information plays a causal role in the generation of particular moral judgments. The manner in which the principles play this role is via ‘proceduralization’ – such principles operate automatically. In contrast to Haidt’s intuitionism, then, our view does not imply that people’s moral reason-giving practices are matters of confabulation. In defense of our view, we appeal to what we call the ‘nonjarring’ character of the phenomenology of making moral judgments and of giving reasons for those judgments. (shrink)

What kind of evidence will lead people to revise their moral beliefs? Moral beliefs are often strongly held convictions, and existing research has shown that morality is rooted in emotion and socialization rather than deliberative reasoning. In addition, more general issues—such as confirmation bias—further impede coherent belief revision. Here, we explored a unique means for inducing belief revision. In two experiments, participants considered a moral dilemma in which an overwhelming majority of people judged that it was inappropriate to take action (...) to maximize utility. Their judgments contradicted a utilitarian principle they otherwise strongly endorsed. Exposure to this scenario led participants to revise their belief in the utilitarian principle, and this revision persisted over several hours. This method provides a new avenue for inducing belief revision. (shrink)

A prominent view of psychopathic moral reasoning suggests that psychopathic individuals cannot properly distinguish between moral wrongs and other types of wrongs. The present study evaluated this view by examining the extent to which 109 incarcerated offenders with varying degrees of psychopathy could distinguish between moral and conventional transgressions relative to each other and to nonincarcerated healthy controls. Using a modified version of the classic Moral/Conventional Transgressions task that uses a forced-choice format to minimize strategic responding, the present study found (...) that total psychopathy score did not predict performance on the task. Task performance was explained by some individual subfacets of psychopathy and by other variables unrelated to psychopathy, such as IQ. The authors conclude that, contrary to earlier claims, insufficient data exist to infer that psychopathic individuals cannot know what is morally wrong. (shrink)

Our brains were designed for tribal life, for getting along with a select group of others and for fighting off everyone else. But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we (...) can find our common ground. (shrink)

In this article I explain why cognitive science (including some neuroscience) matters for normative ethics. First, I describe the dual-process theory of moral judgment and briefly summarize the evidence supporting it. Next I describe related experimental research examining influences on intuitive moral judgment. I then describe two ways in which research along these lines can have implications for ethics. I argue that a deeper understanding of moral psychology favors certain forms of consequentialism over other classes of normative moral theory. I (...) close with some brief remarks concerning the bright future of ethics as an interdisciplinary enterprise. (shrink)

A traditional idea is that moral judgment involves more than calculating the consequences of actions; it also requires an assessment of the agent's intentions, the act's nature, and whether the agent uses another person as a means to her ends. I survey experimental developments suggesting that ordinary people often tacitly reason in terms of such deontological rules. It's now unclear whether we should posit a traditional form of the doctrine of double effect. However, further research suggests that a range of (...) non-consequentialist factors influence moral judgment, including intentions, commissions, personal harm, and agent-centered commitments. Many, if not all, such factors appear to affect how involved the agent is in bringing about an outcome. (shrink)

: To what extent do moral judgments depend on conscious reasoning from explicitly understood principles? We address this question by investigating one particular moral principle, the principle of the double effect. Using web-based technology, we collected a large data set on individuals’ responses to a series of moral dilemmas, asking when harm to innocent others is permissible. Each moral dilemma presented a choice between action and inaction, both resulting in lives saved and lives lost. Results showed that: patterns of moral (...) judgments were consistent with the principle of double effect and showed little variation across differences in gender, age, educational level, ethnicity, religion or national affiliation and a majority of subjects failed to provide justifications that could account for their judgments. These results indicate that the principle of the double effect may be operative in our moral judgments but not open to conscious introspection. We discuss these results in light of current psychological theories of moral cognition, emphasizing the need to consider the unconscious appraisal system that mentally represents the causal and intentional properties of human action.

Should laws about sex and pornography be based on social conventions about what is disgusting? Should felons be required to display bumper stickers or wear T-shirts that announce their crimes? This powerful and elegantly written book, by one of America's most influential philosophers, presents a critique of the role that shame and disgust play in our individual and social lives and, in particular, in the law.Martha Nussbaum argues that we should be wary of these emotions because they are associated in (...) troubling ways with a desire to hide from our humanity, embodying an unrealistic and sometimes pathological wish to be invulnerable. Nussbaum argues that the thought-content of disgust embodies "magical ideas of contamination, and impossible aspirations to purity that are just not in line with human life as we know it." She argues that disgust should never be the basis for criminalizing an act, or play either the aggravating or the mitigating role in criminal law it currently does. She writes that we should be similarly suspicious of what she calls "primitive shame," a shame "at the very fact of human imperfection," and she is harshly critical of the role that such shame plays in certain punishments.Drawing on an extraordinarily rich variety of philosophical, psychological, and historical references--from Aristotle and Freud to Nazi ideas about purity--and on legal examples as diverse as the trials of Oscar Wilde and the Martha Stewart insider trading case, this is a major work of legal and moral philosophy.

People can be disgusted by the concrete and by the abstract -- by an object they find physically repellent or by an ideology or value system they find morally abhorrent. Different things will disgust different people, depending on individual sensibilities or cultural backgrounds. In _Yuck!_, Daniel Kelly investigates the character and evolution of disgust, with an emphasis on understanding the role this emotion has come to play in our social and moral lives. Disgust has recently been riding a swell of (...) scholarly attention, especially from those in the cognitive sciences and those in the humanities in the midst of the "affective turn." Kelly proposes a cognitive model that can accommodate what we now know about disgust. He offers a new account of the evolution of disgust that builds on the model and argues that expressions of disgust are part of a sophisticated but largely automatic signaling system that humans use to transmit information about what to avoid in the local environment. He shows that many of the puzzling features of moral repugnance tinged with disgust are by-products of the imperfect fit between a cognitive system that evolved to protect against poisons and parasites and the social and moral issues on which it has been brought to bear. Kelly's account of this emotion provides a powerful argument against invoking disgust in the service of moral justification. (shrink)

The uniquely human emotion of disgust is intimately connected to morality in many, perhaps all, cultures. We report two studies suggesting that a predisposition to feel disgust is associated with more conservative political attitudes, especially for issues related to the moral dimension of purity. In the first study, we document a positive correlation between disgust sensitivity and self-reported conservatism in a broad sample of US adults. In Study 2 we show that while disgust sensitivity is associated with more conservative attitudes (...) on a range of political issues, this relationship is strongest for purity-related issues—specifically, abortion and gay marriage.

Intuition—spontaneous, nondeliberative assessment—has long been indispensable in theoretical and practical philosophy alike. Recent research by psychologists and experimental philosophers has challenged our understanding of the nature and authority of moral intuitions by tracing them to “fast,” “automatic,” “button-pushing” responses of the affective system. This view of the affective system contrasts with a growing body of research in affective neuroscience which suggests that it is instead a flexible learning system that generates and updates a multidimensional evaluative landscape to guide decision and (...) action. With this latter view in mind, I revisit some of the classic hypothetical scenarios used in experimental moral psychology. (shrink)

Recent behavioral experiments, along with imaging experiments and neuropsychological studies appear to support the hypothesis that emotions play a causal or constitutive role in moral judgment. Those who resist this hypothesis tend to suggest that affective mechanisms are better suited to play a modulatory role in moral cognition. But I argue that claims about the role of emotion in moral cognition frame the debate in ways that divert attention away from other plausible hypotheses. I suggest that the available data may (...) be more plausibly explained by appeal to predictive and evaluative mechanisms, which are neither wholly affective nor straightforwardly cognitive. By recognizing this fact, we can begin to see why questions about the role of emotion in moral psychology are likely to be empirically misguided. (shrink)

According to the quasi-perceptualist account of philosophical intuitions, they are intellectual appearances that are psychologically and epistemically analogous to perceptual appearances. Moral intuitions share the key characteristics of other intuitions, but can also have a distinctive phenomenology and motivational role. This paper develops the Humean claim that the shared and distinctive features of substantive moral intuitions are best explained by their being constituted by moral emotions. This is supported by an independently plausible non-Humean, quasi-perceptualist theory of emotion, according to which (...) the phenomenal feel of emotions is crucial for their intentional content. (shrink)

Mind perception entails ascribing mental capacities to other entities, whereas moral judgment entails labeling entities as good or bad or actions as right or wrong. We suggest that mind perception is the essence of moral judgment. In particular, we suggest that moral judgment is rooted in a cognitive template of two perceived minds—a moral dyad of an intentional agent and a suffering moral patient. Diverse lines of research support dyadic morality. First, perceptions of mind are linked to moral judgments: dimensions (...) of mind perception (agency and experience) map onto moral types (agents and patients), and deficits of mind perception correspond to difficulties with moral judgment. Second, not only are moral judgments sensitive to perceived agency and experience, but all moral transgressions are fundamentally understood as agency plus experienced suffering—that is, interpersonal harm—even ostensibly harmless acts such as purity violations. Third, dyadic morality uniquely accounts for the phenomena of dyadic completion (seeing agents in response to patients, and vice versa), and moral typecasting (characterizing others as either moral agents or moral patients). Discussion also explores how mind perception can unify morality across explanatory levels, how a dyadic template of morality may be developmentally acquired, and future directions. (shrink)

Recent empirical research seems to show that emotions play a substantial role in moral judgment. Perhaps the most important line of support for this claim focuses on disgust. A number of philosophers and scientists argue that there is adequate evidence showing that disgust significantly influences various moral judgments. And this has been used to support or undermine a range of philosophical theories, such as sentimentalism and deontology. I argue that the existing evidence does not support such arguments. At best it (...) suggests something rather different: that moral judgment can have a minor emotive function, in addition to a substantially descriptive one. (shrink)

We present a unified empirical and philosophical account of moral consistency reasoning, a distinctive form of moral reasoning that exposes inconsistencies among moral judgments about concrete cases. Judgments opposed in belief or in emotion and motivation are inconsistent when the cases are similar in morally relevant respects. Moral consistency reasoning, we argue, regularly shapes moral thought and feeling by coordinating two systems described in dual process models of moral cognition. Our empirical explanation of moral change fills a gap in the (...) empirical literature, making psychologically plausible a defensible new model of justified moral change and a hybrid theory of moral judgment.

Are disgusting or disrespectful actions judged to be moral violations, even when they are harmless? Stories about victimless yet offensive actions (such as cleaning one's toilet with a flag) were presented to Brazilian and U.S. adults and children of high and low socioeconomic status (N = 360). Results show that college students at elite universities judged these stories to be matters of social convention or of personal preference. Most other Ss, especially in Brazil, took a moralizing stance toward these actions. (...) For these latter Ss, moral judgments were better predicted by affective reactions than by appraisals of harmfulness. Results support the claims of cultural psychology (R.A. Shweder, 1991a) and suggest that cultural norms and culturally shaped emotions have a substantial impact on the domain of morality and the process of moral judgment. Suggestions are made for building cross-culturally valid models of moral judgment. (shrink)

Research on moral judgment has been dominated by rationalist models, in which moral judgment is thought to be caused by moral reasoning. The author gives 4 reasons for considering the hypothesis that moral reasoning does not cause moral judgment; rather, moral reasoning is usually a post hoc construction, generated after a judgment has been reached. The social intuitionist model is presented as an alternative to rationalist models. The model is a social model in that it deemphasizes the private reasoning done (...) by individuals and emphasizes instead the importance of social and cultural influences. The model is an intuitionist model in that it states that moral judgment is generally the result of quick, automatic evaluations (intuitions). The model is more consistent than rationalist models with recent findings in social, cultural, evolutionary, and biological psychology, as well as in anthropology and primatology. (shrink)

While there is much evidence for the influence of automatic emotional responses on moral judgment, the roles of reflection and reasoning remain uncertain. In Experiment 1, we induced subjects to be more reflective by completing the Cognitive Reflection Test prior to responding to moral dilemmas. This manipulation increased utilitarian responding, as individuals who reflected more on the CRT made more utilitarian judgments. A follow-up study suggested that trait reflectiveness is also associated with increased utilitarian judgment. In Experiment 2, subjects considered (...) a scenario involving incest between consenting adult siblings, a scenario known for eliciting emotionally driven condemnation that resists reasoned persuasion. Here, we manipulated two factors related to moral reasoning: argument strength and deliberation time. These factors interacted in a manner consistent with moral reasoning: A strong argument defending the incestuous behavior was more persuasive than a weak argument, but only when increased deliberation time encouraged subjects to reflect.

Neuroimaging studies on moral decision-making have thus far largely focused on differences between moral judgments with opposing utilitarian (well-being maximizing) and deontological (duty-based) content. However, these studies have investigated moral dilemmas involving extreme situations, and did not control for two distinct dimensions of moral judgment: whether or not it is intuitive (immediately compelling to most people) and whether it is utilitarian or deontological in content. By contrasting dilemmas where utilitarian judgments are counterintuitive with dilemmas in which they are intuitive, we (...) were able to use functional magnetic resonance imaging to identify the neural correlates of intuitive and counterintuitive judgments across a range of moral situations. Irrespective of content (utilitarian/deontological), counterintuitive moral judgments were associated with greater difficulty and with activation in the rostral anterior cingulate cortex, suggesting that such judgments may involve emotional conflict; intuitive judgments were linked to activation in the visual and premotor cortex. In addition, we obtained evidence that neural differences in moral judgment in such dilemmas are largely due to whether they are intuitive and not, as previously assumed, to differences between utilitarian and deontological judgments. Our findings therefore do not support theories that have generally associated utilitarian and deontological judgments with distinct neural systems. (shrink)

��Is moral judgment accomplished by intuition or conscious reasoning? An answer demands a detailed account of the moral principles in question. We investigated three principles that guide moral judgments: (a) Harm caused by action is worse than harm caused by omission, (b) harm intended as the means to a goal is worse than harm foreseen as the side effect of a goal, and (c) harm involving physical contact with the victim is worse than harm involving no physical contact. Asking whether (...) these principles are invoked to explain moral judgments, we found that subjects generally appealed to the first and third principles in their justifications, but not to the second. This finding has significance for methods and theories of moral psychology: The moral principles used in judgment must be directly compared with those articulated in justification, and doing so shows that some moral principles are available to conscious reasoning whereas others are not.

Sentimental Rules is an ambitious and highly interdisciplinary work, which proposes and defends a new theory about the nature and evolution of moral judgment. In it, philosopher Shaun Nichols develops the theory that emotions play a critical role in both the psychological and the cultural underpinnings of basic moral judgment. Nichols argues that our norms prohibiting the harming of others are fundamentally associated with our emotional responses to those harms, and that such 'sentimental rules' enjoy an advantage in cultural evolution, (...) which partly explains the success of certain moral norms. This has sweeping and exciting implications for philosophical ethics. Nichols builds on an explosion of recent intriguing experimental work in psychology on our capacity for moral judgment and shows how this empirical work has broad import for enduring philosophical problems. The result is an account that illuminates fundamental questions about the character of moral emotions and the role of sentiment and reason in how we make our moral judgments. This work should appeal widely across philosophy and the other disciplines that comprise cognitive science. (shrink)

The burgeoning science of ethics has produced a trend toward pessimism. Ordinary moral thought and action, we’re told, are profoundly influenced by arbitrary factors and ultimately driven by unreasoned feelings. This book counters the current orthodoxy on its own terms by carefully engaging with the empirical literature. The resulting view, optimistic rationalism, shows the pervasive role played by reason, and ultimately defuses sweeping debunking arguments in ethics. The science does suggest that moral knowledge and virtue don’t come easily. However, despite (...) the heavy influence of automatic and unconscious processes that have been shaped by evolutionary pressures, we needn’t reject ordinary moral psychology as fundamentally flawed or in need of serious repair. Reason can be corrupted in ethics just as in other domains, but a special pessimism about morality in particular is unwarranted. Moral judgment and motivation are fundamentally rational enterprises not beholden to the passions. (shrink)

Disgust originated as an evolutionary adaptation for avoiding disease, but it has since infiltrated morality. Many philosophers are skeptical of moral disgust. Skeptics argue that disgust is unreliable and harmful, and that we should eliminate or minimize feelings of disgust in moral thought. However, these arguments are unsuccessful. They do not show that disgust is more problematic than other emotions implicated in morality. Moreover, empirical research suggests that disgust supports important norms and values. Disgust is frequently elicited by “reciprocity violations,” (...) i.e., acts of cheating, dishonesty, and exploitation. The emotion is a fitting response because it accurately reflects the ability of these moral wrongs to pollute and to circulate. Repurposing its original functions, moral disgust motivates social exclusion, tracks the spread of immorality, and acts as a signaling system to coordinate sanctioning. Instead of expunging ourselves of moral disgust, then, we should seek to understand its virtues and its vices. (shrink)

Experimental research suggests that people draw a moral distinction between bad outcomes brought about as a means versus a side effect (or byproduct). Such findings have informed multiple psychological and philosophical debates about moral cognition, including its computational structure, its sensitivity to the famous Doctrine of Double Effect, its reliability, and its status as a universal and innate mental module akin to universal grammar. But some studies have failed to replicate the means/byproduct effect especially in the absence of other factors, (...) such as personal contact. So we aimed to determine how robust the means/byproduct effect is by conducting a meta-analysis of both published and unpublished studies (k = 101; 24,058 participants). We found that while there is an overall small difference between moral judgments of means and byproducts (standardized mean difference = 0.87, 95% CI 0.67 – 1.06; standardized mean change = 0.57, 95% CI 0.44 – 0.69; log odds ratio = 1.59, 95% CI 1.15 – 2.02), the mean effect size is primarily moderated by whether the outcome is brought about by personal contact, which typically involves the use of personal force.

Western philosophers have generally neglected honor as a moral phenomenon worthy of serious study. Appiah’s recent work on honor in moral revolutions is an important exception, but even he is careful to separate honor from morality, regarding it as only “an ally” of morality. In this paper we take Appiah to be right about the psychological, social, and historical role honor has played in three notable moral revolutions, but wrong about the moral nature of honor. We defend two new theses: (...) First, honor is an emotional and moral form of recognition respect that can hinder or aid moral progress. Second, honor, so conceived, can play a rational role in progressive moral change, as it did among the working class in the British abolition of slave trade, when the pressure of moral consistency moved them to protest American slavery as an affront to their honor without change in their moral belief that slavery is wrong.

Is the science of moral cognition usefully modelled on aspects of Universal Grammar? Are human beings born with an innate 'moral grammar' that causes them to analyse human action in terms of its moral structure, with just as little awareness as they analyse human speech in terms of its grammatical structure? Questions like these have been at the forefront of moral psychology ever since John Mikhail revived them in his influential work on the linguistic analogy and its implications for jurisprudence (...) and moral theory. In this seminal book, Mikhail offers a careful and sustained analysis of the moral grammar hypothesis, showing how some of John Rawls' original ideas about the linguistic analogy, together with famous thought experiments like the trolley problem, can be used to improve our understanding of moral and legal judgement.

Various social animal species have been noted to inhibit aggressive attacks when a conspecific displays submission cues. Blair (1993) has suggested that humans possess a functionally similar mechanism which mediates the suppression of aggression in the context of distress cues. He has suggested that this mechanism is a prerequisite for the development of the moral/conventional distinction; the consistently observed distinction in subject's judgments between moral and conventional transgressions. Psychopaths may lack this violence inhibitor. A causal model is developed showing how (...) the lack of this mechanism would explain the core behavioural symptoms associated with the psychopathic disorder. A prediction of such a causal model would be that psychopaths should fail to make the moral/conventional distinction. This prediction was confirmed. The implication of this finding for other theories of morality is discussed. (shrink)

In this essay, I draw on Haidt’s and Baron’s respective insights in the service of a bit of philosophical psychoanalysis. I will argue that deontological judgments tend to be driven by emotional responses, and that deontological philosophy, rather than being grounded in moral reasoning, is to a large extent3 an exercise in moral rationalization. This is in contrast to consequentialism, which, I will argue, arises from rather different psychological processes, ones that are more “cognitive,” and more likely to involve genuine (...) moral reasoning. These claims are strictly empirical, and I will defend them on the basis of the available evidence. Needless to say, my argument will be speculative and will not be conclusive. Beyond this, I will argue that if these empirical claims are true, they may have normative implications, casting doubt on deontology as a school of normative moral thought. (shrink)

Is it wrong to torture prisoners of war for fun? Is it wrong to yank on someone’s hair with no provocation? Is it wrong to push an innocent person in front of a train in order to save five innocent people tied to the tracks? If you are like most people, you answered "yes" to each of these questions. A venerable account of human moral judgment, influential in both philosophy and psychology, holds that these judgments are underpinned by internally represented (...) principles or rules and reasoning about whether particular cases fall under those rules. Recently, this view has come under sustained attack from multiple quarters, and now looks to be in danger of being discarded. In this chapter we consider this evidence, and find that it does not support the elimination of rules from moral psychology. (shrink)

Metaethical questions are typically held to be a priori , and therefore impervious to empirical evidence. Here I examine the metaethical claim that motive-internalism about belief , the position that moral beliefs are intrinsically motivating, is true. I argue that belief-internalists are faced with a dilemma. Either their formulation of internalism is so weak that it fails to be philosophically interesting, or it is a substantive claim but can be shown to be empirically false. I then provide evidence for the (...) falsity of substantive belief-internalism. I describe a group of brain-damaged patients who sustain impairment in their moral sensibility: although they have normal moral beliefs and make moral judgments, they are not inclined to act in accordance with those beliefs and judgments. Thus, I argue that they are walking counterexamples to the substantive internalist claim. In addition to constraining our conception of moral reasoning, this argument stands as an example of how empirical evidence can be relevantly brought to bear on a philosophical question typically viewed to be a priori.

Rationalists about the psychology of moral judgment argue that moral cognition has a rational foundation. Recent challenges to this account, based on findings in the empirical psychology of moral judgment, contend that moral thinking has no rational basis. In this book, Hanno Sauer argues that moral reasoning does play a role in moral judgment—but not, as is commonly supposed, because conscious reasoning produces moral judgments directly. Moral reasoning figures in the acquisition, formation, maintenance, and reflective correction of moral intuitions. Sauer (...) proposes that when we make moral judgments we draw on a stable repertoire of intuitions about what is morally acceptable, which we have acquired over the course of our moral education—episodes of rational reflection that have established patterns for automatic judgment foundation. Moral judgments are educated and rationally amenable moral intuitions. -/- Sauer engages extensively with the empirical evidence on the psychology of moral judgment and argues that it can be shown empirically that reasoning plays a crucial role in moral judgment. He offers detailed counterarguments to the anti-rationalist challenge (the claim that reason and reasoning play no significant part in morality and moral judgment) and the emotionist challenge (the argument for the emotional basis of moral judgment). Finally, he uses Joshua Greene's Dual Process model of moral cognition to test the empirical viability and normative persuasiveness of his account of educated intuitions. Sauer shows that moral judgments can be automatic, emotional, intuitive, and rational at the same time. (shrink)

The last two decades have seen tremendous growth in biological research on psychopathy, a mental disorder distinguished by traits including a lack of empathy or emotional response, egocentricity, impulsivity, and stimulation seeking. But how does a psychopath’s brain work? What makes a psychopath? Psychopathy provides a concise, non-technical overview of the research in the areas of genetics, hormones, brain imaging, neuropsychology, environmental influences, and more, focusing on explaining what we currently know about the biological foundations for this disorder and offering (...) insights into prediction, intervention, and prevention. It also offers a nuanced discussion of the ethical and legal implications associated with biological research on psychopathy. How much of this disorder is biologically based? Should offenders with psychopathic traits be punished for their crimes if we can show that biological factors contribute? The text clearly assesses the conclusions that can and cannot be drawn from existing biological research, and highlights the pressing considerations this research demands. (shrink)

We examined the effects of order of presentation on the moral judgments of professional philosophers and two comparison groups. All groups showed similar-sized order effects on their judgments about hypothetical moral scenarios targeting the doctrine of the double effect, the action-omission distinction, and the principle of moral luck. Philosophers' endorsements of related general moral principles were also substantially influenced by the order in which the hypothetical scenarios had previously been presented. Thus, philosophical expertise does not appear to enhance the stability (...) of moral judgments against this presumably unwanted source of bias, even given familiar types of cases and principles.

The manifest dissociation between our capacity to make moral judgments and our ability to provide justifications for them, a phenomenon labeled Moral Dumbfounding, has important implications for the theory and practice of moral psychology. I articulate and develop the Linguistic Analogy as a robust alternative to existing sentimentalist models of moral judgment inspired by this phenomenon. The Linguistic Analogy motivates a crucial distinction between moral acceptability and moral permissibility judgments, and thereby calls into question prevailing methods used in the study (...) of moral judgment. Indeed, the judgments that are the focus of most current empirical work in moral psychology are not proper targets of scientific study. (shrink)

Questions regarding the nature of moral judgment loom large in moral philosophy. Perhaps the most basic of these questions asks how, exactly, moral judgments and moral rules are to be defined; what features distinguish them from other sorts of rules and judgments? A related question concerns the extent to which emotion and reason guide moral judgment. Are moral judgments made mainly on the basis of reason, or are they primarily the products of emotion? As an example of the former view, (...) Kant held all moral requirements to be derived from a principle of rationality (the categorical imperative). As an example of the latter, Hume famously claimed that reason is “the slave of the passions” and that moral judgments stem from the moral emotions. When addressing these issues, philosophers have largely relied on the traditional tools of philosophical analysis, along with introspection, anecdotal evidence and armchair speculation. In recent years, however, a rich body experimental psychology has emerged which, in the view of a growing number of philosophers, casts important new light on these venerable questions. Our aim, in this chapter, is to illustrate how empirical methods can help move traditional philosophical debates forward in interesting and important ways. Since space does not permit an exhaustive survey of the relevant experimental work, we will focus on a few of the most compelling examples. (shrink)

In this paper, I review the primary arguments for the traditional position that holds emotions as antagonistic to moral judgments. I argue that this position is untenable given the information about emotions and emotional processes that has emerged in the psychological literature of recent years. I then offer a theoret- ical model of emotive moral judgment that takes a closer look at how emotions, specifically empathy, play an integral role in the process of moral judgment. I argue that emotions should (...) not be dismissed as irrelevant or harmful to moral evaluations, but that affect can actually aid moral deliberations. The emphasis here will be on moral judgments (i.e., judgments concerning the rightness or wrongness of situations, actions, or individuals); I will not deal directly with the otherwise important issue of the role of emotions in moral behavior. The em- phasis will also be on empathy, as it seems to be the most prototypical moral emotion and is certainly the most widely discussed. (shrink)

Theoretical models and correlational research suggest that anger and disgust play different roles in moral judgment. Anger is theorized to underlie reactions to crimes against persons, such as battery and unfairness, and disgust is theorized to underlie reactions to crimes against nature, such as sexual transgressions and cannibalism. To date, however, it has not been shown that induction of these two emotions has divergent effects. In this experiment we show divergent effects of anger and disgust. We use sounds to elicit (...) anger and disgust, and participants are then asked to consider moral vignettes. As compared to disgust and control condition, anger increases severity of judgments about crimes against persons, and disgust increases severity of judgments about crimes against nature, but not conversely.

Empirical research in the field of moral cognition is increasingly being used to draw conclusions in philosophical moral psychology, in particular regarding sentimentalist and rationalist accounts of moral judgment. This paper calls for a reassessment of both the empirical and philosophical conclusions being drawn from the moral cognition research. It is proposed that moral decision making is best understood as a species of Kahneman and Frederick's dual-process model of decision making. According to this model, emotional intuition-generating processes and reflective processes (...) operate in an integrated way in moral deliberation, and metacognition is assigned an essential role in the monitoring and shaping of moral intuitions. In combination with observations from philosophical moral psychology, this proposal cautions against endorsing simple sentimentalism or rejecting rationalist accounts on the basis of the moral cognition research.
