People expect artificial moral advisors to be more utilitarian and distrust utilitarian moral advisors.

As machines powered by artificial intelligence increase in their technological capacities, there is a growing interest in the theoretical and practical idea of artificial moral advisors (AMAs): systems powered by artificial intelligence that are explicitly designed to assist humans in making ethical decisions. Across four pre-registered studies (total N = 2604) we investigated how people perceive and trust artificial moral advisors compared to human advisors. Extending previous work on algorithmic aversion, we show that people have a significant aversion to AMAs (vs humans) giving moral advice, while also showing that this is particularly the case when advisors - human and AI alike - gave advice based on utilitarian principles.

The impact of generative artificial intelligence on socioeconomic inequalities and policy making.

Generative artificial intelligence (AI) has the potential to both exacerbate and ameliorate existing socioeconomic inequalities. In this article, we provide a state-of-the-art interdisciplinary overview of the potential impacts of generative AI on (mis)information and three information-intensive domains: work, education, and healthcare. Our goal is to highlight how generative AI could worsen existing inequalities while illuminating how AI may help mitigate pervasive social problems.

Does it matter who harmed whom? A cross-cultural study of moral judgments about harm by and to insiders and outsiders.

Unlabelled: This cross-cultural study compared judgments of moral wrongness for physical and emotional harm with varying combinations of in-group vs. out-group agents and victims across six countries: the United States of America (N = 937), the United Kingdom (N = 995), Romania (N = 782), Brazil (N = 856), South Korea (N = 1776), and China (N = 1008). Consistent with our hypothesis we found evidence of an insider agent effect, where moral violations committed by outsider agents are generally considered more morally wrong than the same violations done by insider agents.

Moral conformity in a digital world: Human and nonhuman agents as a source of social pressure for judgments of moral character.

Could judgments about others' moral character be changed under group pressure produced by human and virtual agents? In Study 1 (N = 103), participants first judged targets' moral character privately and two weeks later in the presence of real humans. Analysis of how many times participants changed their private moral judgments under group pressure showed that moral conformity occurred, on average, 43% of the time. In Study 2 (N = 138), we extended this using Virtual Reality, where group pressure was produced either by avatars allegedly controlled by humans or AI.

Vaccine Nationalism Counterintuitively Erodes Public Trust in Leaders.

Global access to resources like vaccines is key for containing the spread of infectious diseases. However, wealthy countries often pursue nationalistic policies, stockpiling doses rather than redistributing them globally. One possible motivation behind vaccine nationalism is a belief among policymakers that citizens will mistrust leaders who prioritize global needs over domestic protection.

Computational ethics.

Technological advances are enabling roles for machines that present novel ethical challenges. The study of 'AI ethics' has emerged to confront these challenges, and connects perspectives from philosophy, computer science, law, and economics. Less represented in these interdisciplinary efforts is the perspective of cognitive science.

The Drunk Utilitarian Revisited: Does Alcohol Really Increase Utilitarianism in Moral Judgment?

The "drunk utilitarian" phenomenon suggests that people are more likely to accept harm for the greater good when they are under the influence of alcohol. This phenomenon conflicts with the ideas that (a) acceptance of pro-sacrificial harm requires inhibitory control of automatic emotional responses to the idea of causing harm and (b) alcohol impairs inhibitory control. This preregistered experiment aimed to provide deeper insights into the effects of alcohol on moral judgments by using a formal modeling approach to disentangle three factors in moral dilemma judgments and by distinguishing between instrumental harm and impartial beneficence as two distinct dimensions of utilitarian psychology.

An empirical bioethical examination of Norwegian and British doctors' views of responsibility and (de)prioritization in healthcare.

In a world with limited resources, allocation of resources to certain individuals and conditions inevitably means fewer resources allocated to other individuals and conditions. Should a patient's personal responsibility be relevant to decisions regarding allocation? In this project we combine the normative and the descriptive, conducting an empirical bioethical examination of how both Norwegian and British doctors think about principles of responsibility in allocating scarce healthcare resources. A large proportion of doctors in both countries supported including responsibility for illness in prioritization decisions.

Moral dilemmas and trust in leaders during a global health crisis.

Trust in leaders is central to citizen compliance with public policies. One potential determinant of trust is how leaders resolve conflicts between utilitarian and non-utilitarian ethical principles in moral dilemmas. Past research suggests that utilitarian responses to dilemmas can both erode and enhance trust in leaders: sacrificing some people to save many others ('instrumental harm') reduces trust, while maximizing the welfare of everyone equally ('impartial beneficence') may increase trust.

The moral self and moral duties.

Recent research has begun treating the perennial philosophical question, "what makes a person the same over time?" as an empirical question. A long tradition in philosophy holds that psychological continuity and connectedness of memories are at the heart of personal identity. More recent experimental work, however, has suggested that persistence of moral character, more than memories, is perceived as essential for personal identity.

Prospective Intention-Based Lifestyle Contracts: mHealth Technology and Responsibility in Healthcare.

As the rising costs of lifestyle-related diseases place increasing strain on public healthcare systems, the individual's role in disease may be proposed as a healthcare rationing criterion. Literature thus far has largely focused on retrospective responsibility in healthcare. The concept of prospective responsibility, in the form of a lifestyle contract, warrants further investigation.

Utilitarianism for animals, Kantianism for people? Harming animals and humans for the greater good.

Most people hold that it is wrong to sacrifice some humans to save a greater number of humans. Do people also think that it is wrong to sacrifice some animals to save a greater number of animals, or do they answer such questions about harm to animals by engaging in a utilitarian cost-benefit calculation? Across 10 studies ( = 4,662), using hypothetical and real-life sacrificial moral dilemmas, we found that participants considered it more permissible to harm a few animals to save a greater number of animals than to harm a few humans to save a greater number of humans. This was explained by a reduced general aversion to harm animals compared with humans, which was partly driven by participants perceiving animals to suffer less and to have lower cognitive capacity than humans.

Does encouraging a belief in determinism increase cheating? Reconsidering the value of believing in free will.

A key source of support for the view that challenging people's beliefs about free will may undermine moral behavior is two classic studies by Vohs and Schooler (2008). These authors reported that exposure to certain prompts suggesting that free will is an illusion increased cheating behavior. In the present paper, we report several attempts to replicate this influential and widely cited work.

Political differences in free will belief are associated with differences in moralization.

In 14 studies, we tested whether political conservatives' stronger free will beliefs were linked to stronger and broader tendencies to moralize and, thus, a greater motivation to assign blame. In Study 1 (meta-analysis of 5 studies, = 308,499) we show that conservatives have stronger tendencies to moralize than liberals, even for moralization measures containing zero political content (e.g.

Switching Tracks? Towards a Multidimensional Model of Utilitarian Psychology.

Sacrificial moral dilemmas are widely used to investigate when, how, and why people make judgments that are consistent with utilitarianism. However, to what extent can responses to sacrificial dilemmas shed light on utilitarian decision making? We consider two key questions. First, how meaningful is the relationship between responses to sacrificial dilemmas, and what is distinctive about a utilitarian approach to morality? Second, to what extent do findings about sacrificial dilemmas generalize to other moral contexts where there is tension between utilitarianism and common-sense intuitions? We argue that sacrificial dilemmas only capture one point of conflict between utilitarianism and common-sense morality, and new paradigms will be necessary to investigate other key aspects of utilitarianism, such as its radical impartiality.

Speciesism, generalized prejudice, and perceptions of prejudiced others.

Philosophers have argued there is a normative relationship between our attitudes towards animals ("speciesism") and other prejudices, and psychological work suggests speciesism relies on similar psychological processes and motivations as those underlying other prejudices. But do laypeople perceive such a connection? We compared perceptions of a target who is high or low on speciesism with those of a target who is high or low on racism (Studies 1-2), sexism (Study 2), or homophobia (Study 3). We find that just like racists, sexists, and homophobes, speciesists were both evaluated more negatively and expected to hold more general prejudicial attitudes and ideologies (e.

Addiction, Identity, Morality.

Background: Recent literature on addiction and judgments about the characteristics of agents has focused on the implications of adopting a "brain disease" versus "moral weakness" model of addiction. Typically, such judgments have to do with what capacities an agent has (e.g.

The costs of being consequentialist: Social inference from instrumental harm and impartial beneficence.

Previous work has demonstrated that people are more likely to trust "deontological" agents who reject harming one person to save many others than "consequentialist" agents who endorse such instrumental harms, which could explain the higher prevalence of non-consequentialist moral intuitions. Yet consequentialism involves endorsing not just instrumental harm, but also impartial beneficence, treating the well-being of every individual as equally important. In four studies (total  = 2086), we investigated preferences for consequentialist vs.

The moral standing of animals: Towards a psychology of speciesism.

We introduce and investigate the philosophical concept of 'speciesism' -the assignment of different moral worth based on species membership -as a psychological construct. In five studies, using both general population samples online and student samples, we show that speciesism is a measurable, stable construct with high interpersonal differences, that goes along with a cluster of other forms of prejudice, and is able to predict real-world decision-making and behavior. In Study 1 we present the development and empirical validation of a theoretically driven Speciesism Scale, which captures individual differences in speciesist attitudes.

Settling for second best: when should doctors agree to parental demands for suboptimal medical treatment?

Background: Doctors sometimes encounter parents who object to prescribed treatment for their children, and request suboptimal substitutes be administered instead (suboptimal being defined as less effective and/or more expensive). Previous studies have focused on parental refusal of treatment and when this should be permitted, but the ethics of requests for suboptimal treatment has not been explored.

Methods: The paper consists of two parts: an empirical analysis and an ethical analysis.

Inference of trustworthiness from intuitive moral judgments.

Moral judgments play a critical role in motivating and enforcing human cooperation, and research on the proximate mechanisms of moral judgments highlights the importance of intuitive, automatic processes in forming such judgments. Intuitive moral judgments often share characteristics with deontological theories in normative ethics, which argue that certain acts (such as killing) are absolutely wrong, regardless of their consequences. Why do moral intuitions typically follow deontological prescriptions, as opposed to those of other ethical theories? Here, we test a functional explanation for this phenomenon by investigating whether agents who express deontological moral judgments are more valued as social partners.

The influence of social preferences and reputational concerns on intergroup prosocial behaviour in gains and losses contexts.

To what extent do people help ingroup members based on a social preference to improve ingroup members' outcomes, versus strategic concerns about preserving their reputation within their group? And do these motives manifest differently when a prosocial behaviour occurs in the context of helping another gain a positive outcome (study 1), versus helping another to avoid losing a positive outcome (study 2)? In both contexts, we find that participants are more prosocial towards ingroup (versus outgroup members) and more prosocial when decisions are public (versus private) but find no interaction between group membership and either anonymity of the decision or expected economic value of helping. Therefore, consistent with a preference-based account of ingroup favouritism, people appear to prefer to help ingroup members more than outgroup members, regardless of whether helping can improve their reputation within their group. Moreover, this preference to help ingroup members appears to take the form of an intuitive social heuristic to help ingroup members, regardless of the economic incentives or possibility of reputation management.
