Meat and morality: The moral foundation of purity, but not harm, predicts attitudes toward cultured meat

Cultured meat (also referred to as cultivated, cell-based, or cell-cultured meat) is a novel food technology that is presented as a method of meat production without reliance on large-scale industrial farming. The pro-cultured meat narrative rests, in part, on a moral foundation: cultured meat is purported to alleviate the environmental and animal welfare harms associated with farmed meat. Despite this narrative, no research has examined which moral values underpin attitudes towards cultured meat. To examine this, we surveyed 1861 participants from the United States and Germany about their moral foundations and their attitudes towards cultured meat. In line with predictions, people who more strongly endorse moral values about purity (i.e., had higher scores on the purity subscale of the moral foundations scale) held more negative attitudes towards cultured meat. However, this relationship was much more consistent among participants from the United States than participants from Germany. Against predictions, attitudes towards cultured meat were not reliably associated with the extent to which people focus on harm as a moral foundation. The latter finding was particularly surprising in light of harm-reduction narratives around cultured meat. These findings demonstrate the need for a more nuanced discussion about, and understanding of, consumer concerns around cultured meat and the values that underpin them.

The long and the short of it: 5-HTTLPR and moral judgement

Differences in moral sentiments are widespread. Increasingly, their biological correlates are investigated to elucidate potential sources of divergent moral attitudes and choices. Serotonin is one such potential modulator. We investigated the effects of a functional serotonergic polymorphism, 5-HTTLPR, which was previously linked to moral choices albeit with inconsistent findings. N = 157 healthy young adults completed a set of congruent and incongruent moral dilemmas. In addition to the traditional moral response score, this set allows by using a process dissociation (PD) approach an estimation a deontological and a utilitarian parameter. While there was no main effect of 5-HTTLPR on any of the three moral judgement parameters, there was an interaction effect between 5-HTTLPR and endocrine status on PD parameters, which was mainly due to the deontological but not the utilitarian parameter. In men and free cycling women, LL homozygotes showed reduced deontological tendencies compared to S allele carriers. Contrariwise, in women using oral contraceptives, LL homozygotes had increased deontology parameter scores. Furthermore, LL genotypes in general reported less difficulty in making harmful choices, which were in addition associated with less negative emotions. The findings suggest that 5-HTTLPR might be involved in modulating cognitive and emotional processes contributing to moral decisions.

Moral judgement among university students in Ica: A view from the perspective of Lawrence Kohlberg

Background: The aim of this study was to identify moral judgement at the preconventional level, the conventional level, and the postconventional level in university students in the tenth semester in Ica, in 2022. Method: The research methodology was descriptive-observational, quantitative and cross-sectional. The population consisted of university students in the tenth semester and the sample consisted of 157 university students. A survey was used as a data collection tool and a questionnaire was used to measure the stages of moral judgement according to Lawrence Kholberg.   Results: It was found that 12.75% of the study sample was in the instructional relativism stage, 23.10% were in interpersonal agreement, 35.76% were in social order and authority, 11.95% were in social contract and finally 3.80% were in universal ethical principles. Conclusion: It was concluded and identified that the stages of moral judgement among the study sample indicate that interpersonal agreement, social order and authority are the most developed among university students.

Not all bilinguals are the same: A meta-analysis of the moral foreign language effect

Emerging evidence shows bilinguals employ different decision-making strategies in their foreign language compared to their native language (known as the Foreign Language Effect). When completing moral dilemmas, accumulating research findings indicate that bilinguals are more likely to endorse the utilitarian option. We conducted a meta-analysis to investigate whether linguistic variables (proficiency, immersion, and language similarity) moderate utilitarian responding to moral dilemmas in a foreign language. A systematic literature search extracted experiments comparing binary responses to moral dilemmas among bilingual participants. Analyses confirmed a moral Foreign Language Effect within personal dilemmas, though this effect was moderated by self-reported reading proficiency, whereby bilinguals with higher self-reported reading proficiency were less likely to make a utilitarian choice. Our findings suggest that not all bilinguals may experience a Foreign Language Effect, with low self-reported reading proficiency being the most likely indicator of whether their response tendencies to a moral dilemma change in the foreign language.

Conformity on moral, social conventional and decency issues in the United Kingdom and Kuwait

Theories in moral psychology have debated whether people's moral judgements are influenced by social processes, such as others' opinions, arguments, and actions. This research investigated conformity with moral, social conventional and decency issues in adults from the United Kingdom (Study 1, N = 50) and Kuwait (Study 2, N = 164). Participants first had to make individual judgements regarding moral, social conventional and decency transgressions. Using a conformity paradigm with low social presence, 5-10 days afterwards participants were presented with the judgements of a more permissive majority. British participants conformed to the majority for decency, and to a lesser extent moral, transgressions. Kuwaiti participants conformed across domains. Furthermore, females in Kuwait conformed more than males. These findings are discussed with reference to the influence of cultural, moral and gender norms on conformity. Furthermore, we consider the contributions of these findings in light of theories of moral judgement and conformity.

Androgenic morality? Associations of sex, oral contraceptive use and basal testosterone levels with moral decision making

Aside from cultural, psychological, or situational factors, differences in moral judgements might also be influenced by biological variables. Since previous studies have reported stronger utilitarian tendencies in men, the relationship between testosterone and moral judgments has gained interest. Utilitarian judgements focus on the consequences of an action in terms of a cost-benefit analysis while deontological judgements are based on rules that are independent of an action's outcome or of situational features. We investigated decisions in moral dilemma situations in N = 157 young adults using a process dissociation approach to allow an independent estimate of underlying utilitarianism and deontology. Significant effects of sex (p = .009) and endocrine status (p = .011) on utilitarianism were found with the highest levels in men and the lowest in free cycling women while oral contraceptive users fell in between. Furthermore, there were correlations of salivary testosterone with utilitarianism in free cycling women (r = .303) and with deontology in men (r = -0.263) while no significant associations between testosterone and moral choices were found in oral contraceptive users. However, the duration of contraceptive use correlated negatively with deontology (r = -.316). The findings underscore the role of sex, endocrine status as well as testosterone in moral judgements but also point to specific associations depending on sex and oral contraceptive use.

Is cleanliness next to abstinence? The effect of cleanliness priming on attitudes towards harm reduction strategies for people with substance use disorders

Can exposure to a cleanliness prime affect moral judgements towards harm reduction strategies (HRS) for individuals with substance use disorders? Our research examined (a) the effect of a cleanliness prime on attitudes towards HRS and (b) whether this effect would be attenuated by a brief educational presentation. Participants were randomly assigned to a priming condition and an educational presentation condition. Results demonstrated that (a) the cleanliness prime did not shift attitudes towards HRS, however, (b) the educational presentations significantly shifted attitudes to be more positive after the Harm Reduction presentation and more negative after the Healthy Living presentation. The literature on priming is mixed and our results support a growing body of research challenging the robustness of cleanliness priming and also demonstrates that brief presentations can change attitudes. Our research has implications for education on the benefits of HRS in reducing disease transmission, refuse in the community, and overdose deaths.

Complexity of heart rate variability during moral judgement of actions and omissions

Recent research strongly supports the idea that cardiac activity is involved in the organisation of behaviour, including social behaviour and social cognition. The aim of this work was to explore the complexity of heart rate variability, as measured by permutation entropy, while individuals were making moral judgements about harmful actions and omissions. Participants (N = 58, 50% women, age 21-52 years old) were presented with a set of moral dilemmas describing situations when sacrificing one person resulted in saving five other people. In line with previous studies, our participants consistently judged harmful actions as less permissible than equivalently harmful omissions (phenomenon known as the "omission bias"). Importantly, the response times were significantly longer and permutation entropy of the heart rate was higher when participants were evaluating harmful omissions, as compared to harmful actions. These results may be viewed as a psychophysiological manifestation of differences in causal attribution between actions and omissions. We discuss the obtained results from the positions of the system-evolutionary theory and propose that heart rate variability reflects complexity of the dynamics of neurovisceral activity within the organism-environment interactions, including their social aspects. This complexity can be described in terms of entropy and our work demonstrates the potential of permutation entropy as a tool of analyzing heart rate variability in relation to current behaviour and observed cognitive processes.

Classic cases revisited: Of hurricanes, cyanide and moral courage

All decisions made by doctors have a moral dimension. When a moral judgement demands a different course of action to one that represents the usual practice, many doctors do struggle. The inability to embrace such decisions can represent moral negligence, as often the consequence is greater suffering for the individual in question or loss of utility for the population. On the other hand, it takes courage to make such decisions as the society fails to accept them, even though decisions made are rational and morally valid. Clinical practice that does not conform to moral judgements can result in moral distress, burn out and job-leave. Reflective practice evaluating moral dimensions of clinical decision making is an important aspect of nurturing humanity, empathy and professionalism in the therapeutic endeavour.

The role of intentions and outcomes in the foreign language effect on moral judgements

We explore the origin of the foreign language effect on moral judgements by assessing whether language context alters the weight given to intentions and outcomes during moral judgement. Specifically, we investigated whether foreign language contexts, compared with native ones, may lead people to focus more on the outcomes of an action and less on the intentions behind it. We report two studies in which participants read scenarios in which the actor's intentions and the resulting consequences were manipulated. As previously shown, people considered both the actor's intentions and the action's outcomes when assessing the damage, cause, moral wrongness, responsibility, and punishment deserved. However, although the foreign language context reduced the impact of intentions on damage assessment, the overall effect of intention and outcomes on these variables was mainly the same in the foreign and the native language contexts. We conclude that differential weighting of intentions and outcomes is unlikely to account for the impact of foreign language use on moral judgement.

Maternal depressive symptoms in childhood and risky behaviours in early adolescence

Longitudinal patterns of maternal depressive symptoms have yet to be linked to risky behaviours, such as substance use or violence, in early adolescence, when such behaviours may be particularly detrimental. This study was carried out to do this. Using data from the UK's Millennium Cohort Study, it modelled the effect of trajectories of maternal depressive symptoms at child ages 3, 5, 7 and 11 years on antisocial behaviour and delinquency at age 11 years (N = 12,494). It also explored their role in predicting moral judgement and attitudes to alcohol at age 11, important predictors of delinquent or antisocial behaviour and alcohol use, respectively. Latent class analysis showed four longitudinal types of maternal depressive symptoms (chronically high, consistently low, moderate-accelerating and moderate-decelerating). Maternal symptom typology predicted antisocial behaviour in males and attitudes to alcohol in females, even after adjusting for youth's age and pubertal status and after correcting for confounding. Specifically, compared to males growing up with never-depressed mothers, those exposed to chronically high or accelerating maternal depressive symptoms were more likely to report engaging in loud and rowdy behaviour, alcohol use and bullying. Females exposed to chronically high maternal depressive symptoms were more likely than those growing up with never-depressed mothers to support the view that alcohol use is harmless. While causal conclusions cannot be drawn, these findings suggest that preventing or treating maternal depressive symptoms in childhood may be a useful approach to reducing future externalising and health-risk behaviours in offspring.

Being similar while judging right and wrong: The effects of personal and situational similarity on moral judgements

This study investigated the effects of similarity with the transgressor and the victim on the perceived immorality of the transgression. Participants read two stories describing a person that cheated on their partner and a police officer that mistreated somebody. In the first story we manipulated participants' personal similarity to the transgressor and in the second their personal similarity to the victim. In each story, participants' past situational similarity to the target character was assessed according to their previous experiences of being in the same position. Results show that both personal and past situational similarity to the transgressor determine less severe moral judgements, while personal and past situational similarity with the victim have the opposite effect. We also tested several potential mediators of these effects, derived from competing theoretical accounts of the influence of similarity on perceived responsibility. Empathy emerged as mediating most of the effects of similarity on moral judgements, except those induced by past situational similarity with the victim. The foreseen probability of being in a similar situation mediated only the effects of similarity to the transgressor, and not those of similarity to the victim. Overall, results highlight the complex mechanisms of the influences of similarity on moral judgements.

Outcome-focused judgements of moral dilemmas in schizophrenia

Previous research on moral judgement in healthy adults suggests a complex interplay of automatic, emotional and deliberative processing. We aimed to advance understanding of these processes by examining moral judgement in individuals with schizophrenia, a population characterised by social-cognitive deficits and interpersonal difficulties. Forty-five patients with schizophrenia and 27 healthy controls judged high-conflict moral dilemmas in response to 3rd-person (i.e. "Is it morally okay to [perform X]?") and 1st-person (i.e. "Would you [perform X]?") probes. Controls were less utilitarian for 3rd-person than 1st-person probes, while this discrepancy did not hold for patients. Utilitarianism in patients correlated with higher levels of interpersonal conflict. Findings suggest that people with schizophrenia focus equally on outcomes across moral-judgement conditions that ought normally to elicit an outcome-action discrepancy, suggesting that they are less influenced by an automatic aversive response to harmful acts in dilemma scenarios, consistent with a dual-process model of moral judgement.

Gain or non-loss: The message matching effect of regulatory focus on moral judgements of other-orientation lies

Previous studies found that individuals with promotion focus are more likely to be persuaded by messages framed in terms of gain-related words; individuals with prevention focus are more likely to be persuaded by messages framed in terms of loss-related words. This is known as the message matching effect of regulatory focus. The present study extended this effect into the field of moral judgement of other-orientation lies. Two experiments were conducted, revealing that (a) individuals with promotion focus judged gain-framed other-orientation lies to be more moral, while individuals with prevention focus judged non-loss-framed other-orientation lies to be more moral; and (b) the subjective processing fluency had a partial mediating role in the message matching effect. Theoretical implications and future research directions were discussed.

What is beautiful brings out what is good in you: The effect of facial attractiveness on individuals' honesty

This study tested whether the presence of an attractive face would influence individuals' honesty. In 2 experiments, 225 participants were asked to predict the outcome of computerised coin-flips and to self-report the accuracy of their predictions. Self-reports were made in the presence of a facial photo of a female who had been rated before the experiment as high attractive, middle attractive or low attractive by other volunteers. Participants were rewarded based on their self-reported (not actual) accuracy. The results showed that subjects tended to give more dishonest self-reports when presented with middle or low attractive facial images than when presented with high attractive images, with self-reported accuracy being significantly higher than the random level. The results of this study show that presented with an attractive face, subjects tend to engage in behaviours that conform to moral codes.

Disgust, but not anger provocation, enhances levator labii superioris activity during exposure to moral transgressions

Physical disgust is elicited by, and amplifies responses to, moral transgressions, suggesting that moral disgust may be a biologically expanded form of physical disgust. However, there is limited research comparing the effects of physical disgust to that of other emotions like anger, making it difficult to determine if the link between disgust and morality is unique. The current research evaluated the specificity of the relationship between disgust and morality by comparing links with anger, using state, physiological and trait measures of emotionality. Participants (N=90) were randomly allocated to have disgust, anger or no emotion induced. Responses to images depicting moral, negative non-moral, and neutral themes were then recorded using facial electromyography. Inducing disgust, but not anger, increased psychophysiological responses to moral themes. Trait disgust, but not trait anger, correlated with levator labii responses to moral themes. These findings provide strong evidence of a unique link between physical disgust and morality.
