In the archetypical action thriller, the plot turns on a critical moment of insight. A car with out-of-state license plates, the gold tooth of the man behind the counter— something tips us off, and loose strands of evidence are woven into a meaningful pattern. Substituting a runaway trolley for suspicious vehicles and dental anomalies, we suggest that a similar denouement is at hand in the field of moral psychology. A number of theoretical proposals that were at one time regarded as (...) unconnected at best, and contradictory at worst, now show hope of reconciliation. Unknowns abound, but there are hints of an emerging consensus. At its core is a recognition that moral judgment is the product of interaction and competition between distinct psychological systems. The goal of the present essay is to describe these systems to highlight important questions for future research. Recent research in moral psychology has focused on two challenges to the longdominant cognitive development paradigm conceived by Piaget and nurtured by Kohlberg (Kohlberg, 1969; Piaget, 1965/1932; Turiel, 1983, 2005). The first challenge claims that moral judgment is accomplished by rapid, automatic and unconscious intuitions (Damasio, 1994; Haidt, 2001; Hauser, 2006; Mikhail, 2000; Schweder & Haidt, 1993), contra the cognitive developmentalists' assumption that moral judgment is the product of conscious principled reasoning. This challenge is built in part on studies demonstrating people's inability to articulate a rational basis for strongly held moral convictions (Bjorklund, Haidt, & Murphy, 2000; Cushman, Young, & Hauser, 2006; Hauser, Cushman, Young, Jin, & Mikhail, 2007; Mikhail, 2000). The second and related challenge claims that moral judgment is driven primarily by affective responses (Blair, 1995; Damasio, 1994; Greene & Haidt, 2002; Schweder & Haidt, 1993), contra the cognitive developmentalists' assumption that moral judgment results from the application of general principles in a "cold" cognitive process..

The thesis we develop in this essay is that all humans are endowed with a moral faculty. The moral faculty enables us to produce moral judgments on the basis of the causes and consequences of actions. As an empirical research program, we follow the framework of modern linguistics.1 The spirit of the argument dates back at least to the economist Adam Smith (1759/1976) who argued for something akin to a moral grammar, and more recently, to the political philosopher John Rawls (...) (1971). The logic of the argument, however, comes from Noam Chomsky’s thinking on language specifically and the nature of knowledge more generally (1986, 1988, 2000; Saporta, 1978). (shrink)
In Natural Justice Binmore offers a game-theoretic map to the landscape of human morality. Following a long tradition of such accounts, Binmore’s argument concerns the forces of biological and cultural evolution that have shaped our judgments about the appropriate distribution of resources. In this sense, Binmore focuses on the morality of outcomes. This is a valuable perspective to which we add a friendly amendment from our own research: moral judgments appear to depend on process just as much as outcome. What (...) matters is not just that the butler is dead, but who killed him, how, and for what reason. Thus, a complete understanding of ‘natural justice’ will entail an account not only of evolutionary pressures, but also of the psychological mechanisms upon which they act. (shrink)
Is the basis of criminality an act that causes harm, or an act undertaken with the belief that one will cause harm? The present study takes a cognitive neuroscience approach to investigating how information about an agent’s beliefs and an action’s conse- quences contribute to moral judgment. We build on prior devel- opmental evidence showing that these factors contribute differ- entially to the young child’s moral judgments coupled with neurobiological evidence suggesting a role for the right tem- poroparietal junction (RTPJ) (...) in belief attribution. Participants read vignettes in a 2 2 design: protagonists produced either a negative or neutral outcome based on the belief that they were causing the negative outcome (‘‘negative’’ belief) or the neutral outcome (‘‘neutral’’ belief). The RTPJ showed significant activation above baseline for all four conditions but was modulated by an interaction between belief and outcome. Specifically, the RTPJ response was highest for cases of attempted harm, where protag- onists were condemned for actions that they believed would cause harm to others, even though the harm did not occur. The results not only suggest a general role for belief attribution during moral judgment, but also add detail to our understanding of the inter- action between these processes at both the neural and behavioral levels.

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.

To understand the structure of moral emotions poses a difficult challenge. For instance, why do liberals and conservatives see some moral issues similarly, but others starkly differently? Or, why does punishment depend on accidental variation in the severity of a harmful outcome, while judgments of wrongfulness or character do not? To resolve the complex design of morality, it helps to think in functional terms. Whether through learning, cultural evolution or natural selection, moral emotions will tend to guide behavior adaptively in (...) ordinary social situations. Thus, considering possible functions of morality can help us to comprehend its form. (shrink)
Ordinary people often make moral judgments that are consistent with philosophical principles and legal distinctions. For example, they judge killing as worse than letting die, and harm caused as a necessary means to a greater good as worse than harm caused as a side-effect (Cushman, Young, & Hauser, 2006). Are these patterns of judgment produced by mechanisms specific to the moral domain, or do they derive from other psychological domains? We show that the action/omission and means/side-effect distinctions affect nonmoral representations (...) and provide evidence that their role in moral judgment is mediated by these nonmoral psychological representations. Specifically, the action/omission distinction affects moral judgment primarily via causal attribution, while the means/side-effect distinction affects moral judgment via intentional attribution. We suggest that many of the specific patterns evident in our moral judgments in fact derive from nonmoral psychological mechanisms, and especially from the processes of causal and intentional attribution.

We review several instances where cognitive research has identified distinct psychological mechanisms for moral judgment that yield conflicting answers to moral dilemmas. In each of these cases, the conflict between psychological mechanisms is paralleled by prominent philosophical debates between different moral theories. A parsimonious account of this data is that key claims supporting different moral theories ultimately derive from the psychological mechanisms that give rise to moral judgments. If this view is correct, it has some important implications for the practice (...) of philosophy. We suggest several ways that moral philosophy and practical reasoning can proceed in the face of discordant theories grounded in diverse psychological mechanisms. (shrink)
An extensive body of research suggests that the distinction between doing and allowing plays a critical role in shaping moral appraisals. Here, we report evidence from a pair of experiments suggesting that the converse is also true: moral appraisals affect doing/allowing judgments. Specifically, morally bad behavior is more likely to be construed as actively ‘doing’ than as passively ‘allowing’. This finding adds to a growing list of folk concepts influenced by moral appraisal, including causation and intentional action. We therefore suggest (...) that the present finding favors the view that moral appraisal plays a pervasive role in shaping diverse cognitive representations across multiple domains. (shrink)
The thesis we develop in this essay is that all humans are endowed with a moral faculty. The moral faculty enables us to produce moral judgments on the basis of the causes and consequences of actions. As an empirical research program, we follow the framework of modern linguistics.1 The spirit of the argument dates back at least to the economist Adam Smith (1759/1976) who argued for something akin to a moral grammar, and more recently, to the political philosopher John Rawls (...) (1971). The logic of the argument, however, comes from Noam Chomsky’s thinking on language specifically and the nature of knowledge more generally (Chomsky, 1986, 1988, 2000; Saporta, 1978). If the nature of moral knowledge is comparable in some way to the nature of linguistic knowledge, as defended recently by Harman (1977), Dwyer (1999, 2004), and Mikhail (2000; in press), then what should we expect to find when we look at the anatomy of our moral faculty? Is there a grammar, and if so, how can the moral grammarian uncover its structure? Are we aware of our moral grammar, its method of operation, and its moment-to-moment functioning in our judgments? Is there a universal moral grammar that allows each child to build a particular moral grammar? Once acquired, are different moral grammars mutually incomprehensible in the same way that a native Chinese speaker finds a native Italian speaker incomprehensible? How does the child acquire a particular moral grammar, especially if her experiences are impoverished relative to the moral judgments she makes? Are there certain forms of brain damage that disrupt moral competence but leave other forms of reasoning intact? And how did this machinery evolve, and for what particular adaptive function? We will have more to say about many of these questions later on, and Hauser (2006) develops others. However, in order to flesh out the key ideas and particular empirical research paths, let us turn to some of the central questions in the study of our language faculty.. (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: (1) 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 (within the limited range of our sample population) and (2) 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.

How are our actions sorted into those that are intentional and those that are not? The philosophical and psychological literature on this topic is livelier now than ever, and we seek to make a contribution to it here. Our guiding question in this article is easy to state and hard to answer: How do various factors— specifically, features of vignettes—that contribute to majority folk judgments that an action is or is not intentional interact in producing the judgment? In pursuing this (...) question we draw on a number of empirical studies, including some of our own, and we sketch some future studies that would shed light on our topic. We emphasize that the factors that concern us here are limited to features of stories to which subject respond: examples include the value of the action asked about, the agent’s being indifferent to performing that action, and the agent’s seeking to perform it. We do not discuss underlying cognitive or emotional processes here, nor do we discuss whether respondents are making errors of any kind. (Both of these issues are discussed in Cushman and Mele [forthcoming].) 1. THREE KINDS OF ACTION In the present section we draw some distinctions that set the stage for our discussion of empirical results. Our actions have effects, and an agent’s bringing about such an effect is itself an action. For example, unbeknownst to Ann, her unlocking the door to her house frightened an intruder. That is, at least one effect of Ann’s unlocking her door was the intruder’s fright. Her bringing about this effect—that is, her frightening the intruder—is an action. Side-effect actions, as we understand this.. (shrink)
Studies of normal individuals reveal an asymmetry in the folk concept of intentional action: an action is more likely to be thought of as intentional when it is morally bad than when it is morally good. One interpretation of these results comes from the hypothesis that emotion plays a critical mediating role in the relationship between an action’s moral status and its intentional status. According to this hypothesis, the negative emotional response triggered by a morally bad action drives the attribution (...) of intent to the actor, or the judgment that the actor acted intentionally. We test this hypothesis by presenting cases of morally bad and morally good action to seven individuals with deficits in emotional processing resulting from damage to the ventromedial prefrontal cortex (VMPC). If normal emotional processing is necessary for the observed asymmetry, then individuals with VMPC lesions should show no asymmetry. Our results provide no support for this hypothesis: like normal individuals, those with VMPC lesions showed the same asymmetry, tending to judge that an action was intentional when it was morally bad but not when it was morally good. Based on this finding, we suggest that normal emotional processing is not responsible for the observed asymmetry of intentional attributions and thus does not mediate the relationship between an action’s moral status and its intentional status.

Each of the food-sharing models that Gurven considers demands unique cognitive capacities. Reciprocal altruism, in particular, requires a suite of complex abilities not required by alternatives such as tolerated scrounging. Integrating cognitive constraints with comparative data from other species can illuminate the adaptive benefits of food sharing in humans.
Recent research in moral psychology has attempted to characterize patterns of moral judgments of actions in terms of the causal and intentional properties of those actions. The present study directly compares the roles of consequence, causation, belief and desire in determining moral judgments. Judgments of the wrongness or permissibility of action were found to rely principally on the mental states of an agent, while judgments of blame and punishment are found to rely jointly on mental states and the causal connection (...) of an agent to a harmful consequence. Also, selectively for judgments of punishment and blame, people who attempt but fail to cause harm more are judged more leniently if the harm occurs by independent means than if the harm does not occur at all. An account of these phenomena is proposed that distinguishes two processes of moral judgment: one which begins with harmful consequences and seeks a causally responsible agent, and the other which begins with an action and analyzes the mental states responsible for that action.
