Bentham's best-known book stands as a classic of both philosophy and jurisprudence. The 1789 work articulates an important statement of the foundations of utilitarian philosophy — it also represents a pioneering study of crime and punishment. Bentham's reasoning remains central to contemporary debates in moral and political philosophy, economics, and legal theory.

Participants compared the mental capacities of various human and nonhuman characters via online surveys. Factor analysis revealed two dimensions of mind perception, Experience and Agency. The dimensions predicted different moral judgments but were both related to valuing of mind.

There are two primary traditions in philosophical theorizing about moral standing—one emphasizing Experience (the capacity to feel pain and pleasure) and one emphasizing Agency (complexity of cognition and lifestyle). In this article we offer an explanation for this divide: Lay judgments about moral standing depend importantly on two independent cues (Experience and Agency), and the two philosophical traditions reflect this aspect of folk moral cognition. In support of this two-source hypothesis, we present the results of a series of new experiments (...) providing evidence for our account of lay judgments about moral standing, and argue that these results lend plausibility to the proposed causal link between folk moral cognition and the philosophical traditions.

According to models of objectification, viewing someone as a body induces de-mentalization, stripping away their psychological traits. Here evidence is presented for an alternative account, where a body focus does not diminish the attribution of all mental capacities but, instead, leads perceivers to infer a different kind of mind. Drawing on the distinction in mind perception between agency and experience, it is found that focusing on someone's body reduces perceptions of agency but increases perceptions of experience. These effects were found (...) when comparing targets represented by both revealing versus nonrevealing pictures or by simply directing attention toward physical characteristics. The effect of a body focus on mind perception also influenced moral intuitions, with those represented as a body seen to be less morally responsible but more sensitive to harm. These effects suggest that a body focus does not cause objectification per se but, instead, leads to a redistribution of perceived mind. (shrink)

When people are trying to determine whether an entity is capable of having certain kinds of mental states, they can proceed either by thinking about the entity from a *functional* standpoint or by thinking about the entity from a *physical* standpoint. We conducted a series of studies to determine how each of these standpoints impact people’s mental state ascriptions. The results point to a striking asymmetry. It appears that ascriptions of states involving phenomenal consciousness are sensitive to physical factors in (...) a way that ascriptions of other states are not. (shrink)

Prior research on the psychology of retribution is complicated by the difficulty of separating retributive and general deterrence motives when studying human offenders . We isolate retribution by investigating judgments about punishing animals, which allows us to remove general deterrence from consideration. Studies 2 and 3 document a “victim identity” effect, such that the greater the perceived loss from a violent animal attack, the greater the belief that the culprit deserves to be killed. Study 3 documents a “targeted punishment” effect, (...) such that the responsive killing of the actual “guilty” culprit is seen as more deserved than the killing of an almost identical yet “innocent” animal from the same species. Studies 4 and 5 extend both effects to participants' acceptance of inflicting pain and suffering on the offending animal at the time of its death, and show that both effects are mediated by measures of retributive sentiment, and not by consequentialist concerns.

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)

Mind perception is the essence of moral judgment. Broadly, moral standing is linked to perceptions of mind, with moral responsibility tied to perceived agency, and moral rights tied to perceived experience. More specifically, moral judgments are based on a fundamental template of two perceived minds—an intentional agent and a suffering patient. This dyadic template grows out of the universal power of harm, and serves as a cognitive working model through which even atypical moral events are understood. Thus, all instances of (...) immorality are perceived to involve both blameworthy agents (i.e., acts) and suffering victims (i.e., consequences). Because moral cognition simultaneously concerns acts and consequences, theories which focus primarily on acts (i.e., deontology) or consequences (i.e., utilitarianism) do not accurately describe moral cognition. Indeed, the phenomenon of dyadic completion suggests that deontological and utilitarian concerns are not only simultaneously active, but also typically compatible and reinforcing: wrong acts have harmful consequences, and harmful consequences stem from wrong acts. The cognitive fusion of acts with consequences suggests that normative conflicts between deontology and utilitarianism are not reflected in everyday moral judgment. This in turn suggests that empirical conclusions drawn from moral dilemmas that pit utilitarianism against deontology—i.e., trolley problems—give an skewed account of moral cognition. (shrink)

The uncanny valley—the unnerving nature of humanlike robots—is an intriguing idea, but both its existence and its underlying cause are debated. We propose that humanlike robots are not only unnerving, but are so because their appearance prompts attributions of mind. In particular, we suggest that machines become unnerving when people ascribe to them experience, rather than agency. Experiment 1 examined whether a machine’s humanlike appearance prompts both ascriptions of experience and feelings of unease. Experiment 2 tested whether a machine capable (...) of experience remains unnerving, even without a humanlike appearance. Experiment 3 investigated whether the perceived lack of experience can also help explain the creepiness of unfeeling humans and philosophical zombies. These experiments demonstrate that feelings of uncanniness are tied to perceptions of experience, and also suggest that experience—but not agency—is seen as fundamental to humans, and fundamentally lacking in machines.
