In this paper, we utilize humanoid robots (more clearly influenced by determined programming) to empirically test children’s developing concepts of choice and action. Using a series of agency attribution and choice prediction tasks, we examined whether children differentiate free will abilities between robots and humans. Results indicated that 5–7-year-old children similarly attributed the ability to choose to both a robot and human child. However, for moral scenarios, participants considered the robot’s actions to be more constrained than the human. These findings demonstrate that children appear to hold a nuanced understanding of choice across agents and across context.

Putting aside the question of whether people from different religions agree about how to answer moral questions, here we investigate a more fundamental question: How much disagreement is there across religions about which issues count as moral in the first place? That is, do people from different religions conceptualize the scope of morality differently? Using a new methodology to map out how individuals conceive of the moral domain, we find dramatic differences among adherents of different religions. Mormon and Muslim participants moralized their religious norms, while Jewish participants did not. Hindu participants in our sample did not seem to make a moral/non-moral distinction of the same kind. These results suggest a profound relationship between religious affiliation and conceptions of the scope of the moral domain.

However, little is known about children's tendencies to attribute the capacity to choose to robots, despite increased contact with robotic agents. In this paper, we compare 5- to 7-year-old children's and adults' attributions of free choice to a robot and to a human child by using a series of tasks measuring agency attribution, action prediction, and choice attribution. In morally neutral scenarios, children ascribed similar levels of free choice to the robot and the human, while adults were more likely to ascribe free choice to the human. For morally relevant scenarios, however, both age groups considered the robot's actions to be more constrained than the human's actions. These findings demonstrate that children and adults hold a nuanced understanding of free choice that is sensitive to both the agent type and constraints within a given scenario.

Gossip allows important rules to be clarified and reinforced, and it allows individuals to keep track of their social networks while strengthening their bonds to the group. The purpose of this study is to decipher the nature of gossip and how it relates to friendship connections. To measure how gossip relates to friendship, participants from men's and women's collegiate competitive rowing (crew) teams (N = 44) noted their friendship connections and their tendencies to gossip about each of their teammates. Using social network analysis, we found that the crew members' friend group connectedness significantly correlated with their positive and negative gossip network involvement. Higher connectedness among friends was associated with less involvement in spreading negative gossip and/or being a target of negative gossip. More central connectedness to the friend group was associated with more involvement in spreading positive gossip and/or being a target of positive gossip. These results suggest that the spread of both positive and negative gossip may influence and be influenced by friendship connections in a social network.

However, because trade-offs exist in valuing different kinds of entities, tabulating total amounts of moral expansiveness may conceal significant individual differences in the relative proportions of moral valuation ascribed to various entities. We hypothesized that some individuals ("tree-huggers") would ascribe greater moral worth to animals and ecosystems than to humans from marginalized or stigmatized groups, while others ("human-lovers") would ascribe greater moral worth to outgroup members than to the natural world. Additionally, because moral valuation is often treated as being zero-sum, we hypothesized that there would be no difference in aggregate levels of moral concern between tree-huggers and human-lovers. Finally, because attributions of mental capacities substantially contribute to moral valuation, we predicted that tree-huggers and human-lovers would show different patterns of mind attribution for animals versus humans. Three studies (N = 985) yielded evidence in support of our hypotheses. First, over one-third of participants valued nature over outgroups. Second, extending moral value to animals and nature was not indicative of more expansive moral concern overall; instead, tree-huggers and human-lovers were identical in their aggregate ascriptions of moral worth. Third, tree-huggers had relatively amplified tendencies to attribute mental capacities to animals and relatively reduced tendencies to attribute mental capacities to outgroup members-thus having elevated rates of both anthropomorphism and dehumanization. These findings necessitate a reconceptualization of both the extension of moral worth and the attribution of minds.

However, research in developmental psychology indicates that the mechanisms underlying these intuitions are not always rational in nature. Specifically, automatic intuitions can emerge passively, through processes such as evolutionary preparedness and enculturation. Although these intuitions are not always emotional, they are not clearly indicative of reason.

We investigated whether judgments of purity transgressions are more or less sensitive to variation in dosage than judgments of harm transgressions. In three studies, adults ( N = 426) made moral evaluations of harm and purity transgressions that systematically varied in dosage (frequency or magnitude). Pairs of low-dosage and high-dosage transgressions were presented such that the same sets of modifiers (e.g., “occasionally” vs. “regularly,” “small” vs. “large”) or amounts (e.g., “millimeter” vs. “centimeter”) were reused across moral domains. Statistical interactions between domain and dosage indicated robust distinctions between the perceived wrongness of high-dosage and low-dosage harms, whereas moral evaluations of impure acts were considerably less influenced by dosage. Our findings support the existence of a cognitive dis...

However, past research has failed to operationally discriminate harm appraisals from appraisals related to injustice. Four studies carefully discriminated harm qua pain/suffering from injustice, alongside appraisals related to impurity, authority, and disloyalty. Appraisals of injustice outperformed appraisals of harm as independent predictors of the judged wrongness of recalled offenses (Study 1). Studies 2a, 2b, and 3 extended these findings using a diverse range of wrongful acts and two different cultural samples—the United States and Greece. In addition to the strong relevance of injustice appraisals, these latter studies uncovered substantial contributions of impurity and authority appraisals. The results inform debates on moral pluralism and the foundations of moral cognition.

We have found evidence that these moral judgments are primarily predicted by people's belief that suicide taints the soul and by independent concerns about purity. This finding is inconsistent with accounts that define morality as fundamentally based upon harm considerations. In this commentary, we respond to a critique of our finding, and we provide further support for our original conclusions. Even when applying new exclusion criteria to our data, an examination of effect sizes demonstrates that concerns about purity robustly and meaningfully explain variance in moral judgments of suicide. While harm concerns sometimes predict moral judgments of suicide alongside purity concerns, they reliably explain a much smaller proportion of the variance than do purity concerns. Therefore, data from six studies continue to suggest that the relevance of harm concerns for moral judgments of suicide is substantially overshadowed by the contribution of purity concerns.

However, suicide is considered immoral even though the perpetrator is also the victim. To determine whether concerns about purity rather than harm predict moral condemnation of suicide, we presented American adults with obituaries describing suicide or homicide victims. While harm was the only variable predicting moral judgments of homicide, perceived harm (toward others, the self, or God) did not significantly account for variance in moral judgments of suicide. Instead, regardless of political and religious views and contrary to explicit beliefs about their own moral judgments, participants were more likely to morally condemn suicide if they (i) believed suicide tainted the victims' souls, (ii) reported greater concerns about purity in an independent questionnaire, (iii) experienced more disgust in response to the obituaries, or (iv) reported greater trait disgust. Thus, suicide is deemed immoral to the extent that it is considered impure.

Yet, research findings are mixed as to whether this information influences folk evaluations of perpetrators’ dispositions, and subsequently, evaluations of their deserved punishments. Previous research has not clearly dissociated the effects of information about perpetrators’ genetic endowment versus their environmental circumstances. Additionally, most research has focused exclusively on violations involving extreme physical harm, often using mock capital sentences cases as examples. To address these gaps in the literature, we employed a “switchedat- birth” paradigm to investigate whether positive or negative information about perpetrators’ genetic or environmental backgrounds influence evaluations of a perpetrator’s mental states, character, and deserved punishment. Across three studies, we varied whether the transgression involved direct harm, an impure act that caused no harm, or a case of moral luck. The results indicate that negative genetic and environmental backgrounds influenced participants’ evaluations of perpetrators’ intentions, free will, and character, but did not influence participants’ punishment decisions. Overall, these results replicate and extend existing findings suggesting that perpetrators’ supposed extenuating circumstances may not mitigate the punishment that others assign to them.

We hypothesized that adults' verbal instruction (" testimony "), as well as emotions such as disgust, would influence children's moralization of apparently harmless actions. To test this hypothesis, 7-year-old children were asked to render moral judgments of novel, seemingly victimless, body-directed or nature-directed actions after being exposed to adults' testimony or to an emotional induction. Study 1 demonstrated that children became more likely to judge actions as " wrong " upon being verbally presented with testimony about disgust or anger— but not upon being directly induced to feel disgusted. Study 2 established that principle-based testimony is an even more powerful source of moralization, and additionally found long-term retention of newly formed moral beliefs. These studies also indicated that children frequently lack introspective insight into the sources of their newly acquired moral reactions; they often invoked welfare-based concerns in their explanations regardless of experimental condition. In sum, this research demonstrates that children rapidly and enduringly moralize entirely unfamiliar, apparently innocuous actions upon exposure to a diverse array of morally relevant testimony.
