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 So we aimed to determine how robust the means/byproduct effect is by conducting a meta-analysis of both published and unpublished studies (k = 101; 24,058 participants).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.

I examine the phenomenon of implicit learning, the process by which knowledge about the rule-governed complexities of the stimulus environment is acquired independently of conscious attempts to do so. Our research with the two seemingly disparate experimental paradigms of synthetic grammar learning and probability learning, is reviewed and integrated with other approaches to the general problem of unconscious cognition. The conclusions reached are as follows: Implicit learning produces a tacit knowledge base that is abstract and representative of the structure of (...) the environment; such knowledge is optimally acquired independently of conscious efforts to learn; and it can be used implicitly to solve problems and make accurate decisions about novel stimulus circumstances. Various epistemological issues and related problems such as intuition, neuroclinical disorders of learning and memory, and the relationship of evolutionary processes to cognitive science are also discussed.

The psychological and neurobiological processes underlying moral judgement have been the focus of many recent empirical studies1–11. Of central interest is whether emotions play a causal role in moral judgement, and, in parallel, how emotion-related areas of the brain contribute to moral judgement. Here we show that six patients with focal bilateral damage to the ventromedial prefrontal cortex (VMPC), a brain region necessary for the normal generation of emotions and, in particular, social emotions12–14, produce an abnor- mally ‘utilitarian’ pattern of (...) judgements on moral dilemmas that pit compelling considerations of aggregate welfare against highly emotionally aversive behaviours (for example, having to sacrifice one person’s life to save a number of other lives)7,8. In contrast, the VMPC patients’ judgements were normal in other classes of moral dilemmas. These findings indicate that, for a selective set of moral dilemmas, the VMPC is critical for normal judgements of right and wrong. The findings support a necessary role for emotion in the generation of those judgements. (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)

Psychopathic behavior is characteristically amoral, but to date research studies have largely failed to identify any systematic differences in moral judgment capability between psychopaths and non-psychopaths. In this study, we investigate whether significant differences in moral judgment emerge when taking into account the phenotypic heterogeneity of the disorder through a well-validated distinction between psychopathic subtypes. Three groups of incarcerated participants [low-anxious psychopaths (n 1⁄4 12), high-anxious psychopaths (n 1⁄4 12) and non-psychopaths (n 1⁄4 24)] completed a moral judgment test involving (...) hypothet- ical dilemmas. The moral dilemmas featured personal (i.e. involving direct physical harm) or impersonal (i.e. involving indirect or remote harm) actions. Compared to non-psychopaths, both groups of psychopaths were significantly more likely to endorse the impersonal actions. However, only the low-anxious psychopaths were significantly more likely to endorse the personal harms when commission of the harm would maximize aggregate welfare the utilitarian choice. High-anxious psychopaths and non-psychopaths did not significantly differ in their personal moral judgments. These results provide novel laboratory evidence of abnormal moral judgment in psychopaths, as well as additional support for the importance of considering psychopathic subtypes. (shrink)

本书中,作者直接剖析了心理变态者,并提出了"其本质是什么"这一令人困扰的问题,揭开了心理变态者的神秘面纱.

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)

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.

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)

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)

There is a long-standing debate in philosophy about whether it is morally permissible to harm one person in order to prevent a greater harm to others and, if not, what is the moral principle underlying the prohibition. Hypothetical moral dilemmas are used in order to probe moral intuitions. Philosophers use them to achieve a reflective equilibrium between intuitions and principles, psychologists to investigate moral decision-making processes. In the dilemmas, the harms that are traded off are almost always deaths. However, the (...) moral principles and psychological processes are supposed to be broader than this, encompassing harms other than death. Further, if the standard pattern of intuitions is preserved in the domain of economic harm, then that would open up the possibility of studying behavior in trolley problems using the tools of experimental economics. We report the results of two studies designed to test whether the standard patterns of intuitions are preserved when the domain and severity of harm are varied. Our findings show that the difference in moral intuitions between bystander and footbridge scenarios is replicated across different domains and levels of physical and non-physical harm, including economic harms.

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)

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)

There is a large tradition of work in moral psychology that explores the capacity for moral judgment by focusing on the basic capacity to distinguish moral violations (e.g. hitting another person) from conventional violations (e.g. playing with your food). However, only recently have there been attempts to characterize the cognitive mechanisms underlying moral judgment (e.g. Cognition 57 (1995) 1; Ethics 103 (1993) 337). Recent evidence indicates that affect plays a crucial role in mediating the capacity to draw the moral/conventional distinction. (...) However, the prevailing account of the role of affect in moral judgment is problematic. This paper argues that the capacity to draw the moral/conventional distinction depends on both a body of information about which actions are prohibited (a Normative Theory) and an affective mechanism. This account leads to the prediction that other normative prohibitions that are connected to an affective mechanism might be treated as non-conventional. An experiment is presented that indicates that “disgust” violations (e.g. spitting at the table), are distinguished from conventional violations along the same dimensions as moral violations.

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)

Recent empirical studies have established that disgust plays a role in moral judgment. The normative significance of this discovery remains an object of philosophical contention, however; ‘disgust skeptics’ such as Martha Nussbaum have argued that disgust is a distorting influence on moral judgment and has no legitimate role to play in assessments of moral wrongness. I argue, pace Nussbaum, that disgust’s role in the moral domain parallels its role in the physical domain. Just as physical disgust tracks physical contamination and (...) pollution, so moral disgust tracks social contamination. I begin by examining the arguments for skepticism about disgust and show that these arguments threaten to overgeneralize and lead to a widespread skepticism about the justifiability of our moral judgments. I then look at the positive arguments for according disgust a role in moral judgment, and suggest that disgust tracks invisible social contagions in much the same way as it tracks invisible physical contagions, thereby serving as a defense against the threat of socio-moral contamination.

In this article, we advance the perspective that distinct emotions amplify different moral judgments, based on the emotion’s core appraisals. This theorizing yields four insights into the way emotions shape moral judgment. We submit that there are two kinds of specificity in the impact of emotion upon moral judgment: domain specificity and emotion specificity. We further contend that the unique embodied aspects of an emotion, such as nonverbal expressions and physiological responses, contribute to an emotion’s impact on moral judgment. Finally, (...) emotions play a key role in determining which issues acquire moral significance in a society over time, in a process known as moralization (Rozin, 1999). The implications of these four observations for future research on emotion and morality are discussed. (shrink)

Despite the wealth of recent work implicating disgust as an emotion central to human morality, the nature of the causal relationship between disgust and moral judgment remains unclear. We distinguish between three related claims regarding this relationship, and argue that the most interesting claim (that disgust is a moralizing emotion) is the one with the least empirical support.

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)

Philosophical and empirical moral psychologists claim that emotions are both necessary and sufficient for moral judgment. The aim of this paper is to assess the evidence in favor of both claims and to show how a moderate rationalist position about moral judgment can be defended nonetheless. The experimental evidence for both the necessity- and the sufficiency-thesis concerning the connection between emotional reactions and moral judgment is presented. I argue that a rationalist about moral judgment can be happy to accept the (...) necessity-thesis. My argument draws on the idea that emotions play the same role for moral judgment that perceptions play for ordinary judgments about the external world. I develop a rationalist interpretation of the sufficiency-thesis and show that it can successfully account for the available empirical evidence. The general idea is that the rationalist can accept the claim that emotional reactions are sufficient for moral judgment just in case a subject’s emotional reaction towards an action in question causes the judgment in a way that can be reflectively endorsed under conditions of full information and rationality. This idea is spelled out in some detail and it is argued that a moral agent is entitled to her endorsement if the way she arrives at her judgment reliably leads to correct moral beliefs, and that this reliability can be established if the subject’s emotional reaction picks up on the morally relevant aspects of the situation.

Means-based harms are frequently seen as forbidden, even when they lead to a greater good. But, are there mitigating factors? Results from five experiments show that judgments about means-based harms are modulated by: 1) Pareto considerations (was the harmed person made worse off?), 2) the directness of physical contact, and 3) the source of the threat (e.g. mechanical, human, or natural). Pareto harms are more permissible than non-Pareto harms, Pareto harms requiring direct physical contact are less permissible than those that (...) do not, and harming someone who faces a mechanical threat is less permissible than harming someone who faces a non-mechanical threat. These results provide insight into the rich representational structure underlying folk-moral computations, including both the independent and interacting roles of the inevitability, directness and source of harm.

Short abstract (98 words). Reasoning is generally seen as a means to improve knowledge and make better decisions. However, much evidence shows that reasoning often leads to epistemic distortions and poor decisions. This suggests that the function of reasoning should be rethought. Our hypothesis is that the function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade. Reasoning so conceived is adaptive given humans’ exceptional dependence on communication and vulnerability to misinformation. A wide range of (...) evidence in the psychology of reasoning and decision making can be reinterpreted and better explained in the light of this hypothesis. (shrink)

In empirically minded research, it is widely agreed that emotions play an important, even essential, role in moral judgment. Experimental research on moral development, psychopathology, helping behavior, moral judgment, and moral justification has been used to support different new forms of sentimentalism. This article reviews this evidence critically and proposes that although it suggests that emotions play a role in moral judgment, it does so in a more limited way than is often assumed to be the case. Some evidence shows (...) merely that emotions play a role in decision-making, other that emotions are implicated in certain types of moral judgment. What is required, it seems, is a new conceptualization of what is at stake in the rationalism versus sentimentalism debate. (shrink)

The moral/conventional task has been widely used to study the emergence of moral understanding in children and to explore the deficits in moral understanding in clinical populations. Previous studies have indicated that moral transgressions, particularly those in which a victim is harmed, evoke a signature pattern of responses in the moral/conventional task: they are judged to be serious, generalizable and not authority dependent. Moreover, this signature pattern is held to be pan‐cultural and to emerge early in development. However, almost all (...) the evidence for these claims comes from studies using harmful transgressions of the sort that primary school children might commit in the schoolyard. In a study conducted on the Internet, we used a much wider range of harm transgressions, and found that they do not evoke the signature pattern of responses found in studies using only schoolyard transgressions. Paralleling other recent work, our study provides preliminary grounds for skepticism regarding many conclusions drawn from earlier research using the moral/conventional task. (shrink)

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)

Jesse Prinz argues that recent work in philosophy, neuroscience, and anthropology supports two radical hypotheses about the nature of morality: moral values are based on emotional responses, and these emotional responses are inculcated by culture, not hard-wired through natural selection. In the first half of the book, Jesse Prinz defends the hypothesis that morality has an emotional foundation. Evidence from brain imaging, social psychology, and psychopathology suggest that, when we judge something to be right or wrong, we are merely expressing (...) our emotions. Prinz argues that these emotions do not track objective features of reality; rather, the rightness and wrongness of an act consists in the fact that people are disposed to have certain emotions towards it. In the second half of the book, he turns to a defense of moral relativism. Moral facts depend on emotional responses, and emotional responses vary from culture to culture. Prinz surveys the anthropological record to establish moral variation, and he draws on cultural history to show how attitudes toward practices such as cannibalism and marriage change over time. He also criticizes evidence from animal behavior and child development that has been taken to support the claim that moral attitudes are hard-wired by natural selection. Prinz concludes that there is no single true morality, but he also argues that some moral values are better than others; moral progress is possible. Throughout the book, Prinz relates his views to contemporary and historical work in philosophical ethics. His views echo themes in the writings of David Hume and Friedrich Nietzsche, but Prinz supports, extends, and revises these classic theories using the resources of cutting-edge cognitive science. The Emotional Construction of Morals will stimulate and challenge anyone who is curious about the nature and origin of moral values. (shrink)

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)

Children are not simply molded by the environment; through constant inference and interpretation, they actively shape their own social world. This book is about that process. Elliot Turiel's work focuses on the development of moral judgment in children and adolescents and, more generally, on their evolving understanding of the conventions of social systems. His research suggests that social judgements are ordered, systematic, subtly discriminative, and related to behavior. His theory of the ways in which children generate social knowledge through their (...) social experiences will be of interest to a wide range of researchers and students in child development and education.

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)

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. (shrink)

It is often claimed that the existence of psychopaths undermines moral rationalism. I examine a recent empirically based argument for this claim and conclude that rationalist accounts of moral judgement and moral reasoning are perfectly compatible with the evidence cited.

Psychopaths have long been of interest to moral philosophers, since a careful examination of their peculiar deficiencies may reveal what features are normally critical to the development of moral agency. What underlies the psychopath's amoralism? A common and plausible answer to this question is that the psychopath lacks empathy. Lack of empathy is also claimed to be a critical impairment in autism, yet it is not at all clear that autistic individuals share the psychopath's amoralism. How is empathy characterized in (...) the literature, and how crucial is empathy, so described, to moral understanding and agency? I argue that an examination of moral thinking in high-functioning autistic people supports a Kantian rather than a Humean account of moral agency. (shrink)

Recent work in cognitive science provides overwhelming evidence for a link between emotion and moral judgment. I review findings from psychology, cognitive neuroscience, and research on psychopathology and conclude that emotions are not merely correlated with moral judgments but they are also, in some sense, both necessary and sufficient. I then use these findings along with some anthropological observations to support several philosophical theories: first, I argue that sentimentalism is true: to judge that something is wrong is to have a (...) sentiment of disapprobation towards it. Second, I argue that moral facts are response-dependent: the bad just is that which cases disapprobation in a community of moralizers. Third, I argue that a form of motivational internalism is true: ordinary moral judgments are intrinsically motivating, and all non-motivating moral judgments are parasitic on these. (shrink)

It is argued that the intuitively sanctioned distinction between beliefs and non-belief states that play a role in the proximate causal history of beliefs is a distinction worth preserving in cognitive psychology. The intuitive distinction is argued to rest on a pair of features exhibited by beliefs but not by subdoxastic states. These are access to consciousness and inferential integration. Harman's view, which denies the distinction between beliefs and subdoxastic states, is discussed and criticized.

This chapter discusses contemporary scientific research on the role of reason and emotion in moral judgment. The literature suggests that moral judgment is influenced by both reasoning and emotion separately, but there is also emerging evidence of the interaction between the two. While there are clear implications for the rationalism-sentimentalism debate, we conclude that important questions remain open about how central emotion is to moral judgment. We also suggest ways in which moral philosophy is not only guided by empirical research (...) but continues to guide it. (shrink)

This book defends the Humean Theory of Motivation, according to which desire drives all action and practical reasoning. -/- Desire motivates us to pursue its object. It makes thoughts of its object pleasant. It focuses attention on its object. Its effects are amplified by vivid representations of its object. These aspects of desire explain why motivation usually accompanies moral belief, how intentions shape our plans, how we exercise willpower, what human selves are, how action can express emotion, why we procrastinate, (...) and how we daydream. The Humean Theory also suggests a new account of moral judgment that upholds objectivity while understanding moral concepts in terms of our feelings. (shrink)

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.

In this essay I argue that moral judgment is a natural kind by developing an empirically grounded theory of the distinctive conceptual content of moral judgments. Psychological research on the moral/conventional distinction suggests that in moral judgments right and wrong, good and bad, praiseworthiness and blameworthiness, etc. are conceptualized as serious, general, authority-independent, and objective. After laying out the theory and the empirical evidence that supports it, I address recent empirical and conceptual objections. Finally, I suggest that the theory uniquely (...) accounts for the possibility of genuine moral agreement and disagreement. (shrink)
