The role of emotion in moral judgment is currently a topic of much debate in moral psychology. One specific claim made by many researchers is that irrelevant feelings of disgust can amplify the severity of moral condemnation. Numerous researchers have found this effect, but there have also been several published failures to replicate it. Clarifying...

Recent theorizing about the cognitive underpinnings of dilemmatic moral judgment has equated slow, deliberative thinking with the utilitarian disposition and fast, automatic thinking with the deontological disposition. However, evidence for the reflective utilitarian hypothesis—the hypothesized link between utilitarian judgment and individual diffe...

Two studies examined the relationship between individual differences in cognitive reflection (CRT) and the tendency to accord genuinely moral (non-conventional) status to a range of counter-normative acts — that is, to treat such acts as wrong regardless of existing social opinion or norms. We contrasted social violations that are intrinsically har...

Do people think of the value of all human lives as equivalent irrespective of age? Affirmations of the equal value of all human lives are culturally prominent, yet much evidence points to the fact that the young are often prioritized over the old in life-and-death decision-making contexts. Studies 1-3 aimed to reconcile this tension by showing that...

Evaluating other people's moral character is a crucial social cognitive task. However, the cognitive processes by which people seek out, prioritize, and integrate multiple pieces of character‐relevant information have not been studied empirically. The first aim of this research was to examine which character traits are considered most important whe...

The book begins by overviewing the timeline of the pandemic and how it affected life, followed by a discussion of the ethics and legal aspects of the pandemic. It then discusses behaviors during the pandemic (e.g., social distancing, protesting) before discussing experiences during the pandemic (e.g., prejudice, well-being, stress, joblessness, fam...

Despite the well-documented costs of word-deed misalignment, hypocrisy permeates our personal, professional, and political lives. Why? We explore one potential explanation: the costs of moral flexibility can outweigh the costs of hypocrisy, making hypocritical moral absolutism a preferred social strategy to admissions of moral nuance. We study this...

The act of suicide is commonly viewed as wrong in some sense, but it is not clear why this is. Based on past empirical research and philosophical theorizing, we test ten different explanations for why suicide is opposed on normative grounds. Using a within-subjects design, Study 1 showed that seven out of ten manipulations had significant effects o...

Background Given prior research finding that young adults are less likely to engage in recommended public health behaviors (PHBs) than older adults, understanding who is and is not likely to engage in PHBs among young adults is crucial to mitigating the effects of the COVID-19 pandemic. Drawing on the Transactional Theory of Stress and Coping, this...

There are many factors that influence jurors' conviction decisions. Using the Model of Moral Motives and Moral Foundations Theory, this study examines one understudied factor that may influence conviction decisions: jurors' moral values. Participants were presented with two different murder trial case summaries (guilty vs. innocent defendant) and w...

The status of disgust as a sociomoral emotion is debated. We conducted a stringent test of whether social stimuli (specifically, political outgroup members) can elicit physical disgust, as distinct from moral or metaphorical disgust. We employed stimuli (male faces) matched on baseline disgustingness, provided other ways for participants to express...

The COVID-19 pandemic has created major upheavals in the lives of people worldwide. The virus has mostly affected elderly populations, but there may be corollary effects on young adults’ psychosocial adjustment due to educational, economic, and occupational disruptions. Using latent class analysis, we examined unique typologies of coping in respons...

To what extent are research results influenced by subjective decisions that scientists make as they design studies? Fifteen research teams independently designed studies to answer five original research questions related to moral judgments, negotiations, and implicit cognition. Participants from 2 separate large samples (total N > 15,000) were then...

May expresses optimism about the source, content, and consequences of moral judgments. However, even if we are optimistic about their source (i.e., reasoning), some pessimism is warranted about their content, and therefore their consequences. Good reasoners can attain moral knowledge, but evidence suggests that most people are not good reasoners, w...

Theories that view emotions as being related in some way to moral judgments suggest that condemning moral emotions should, at a minimum, be understood by laypeople to coincide with judgments of moral disapproval. Seven studies (total N = 826) tested the extent to which anger and disgust align with this criterion. We observed that while anger is und...

We propose that methods from the study of category-based induction can be used to test the accuracy of theories of moral judgment. We had participants rate the likelihood that a person would engage in a variety of actions, given information about a previous behavior. From these likelihood ratings, we extracted a hierarchical, taxonomic model of how...

Disgust-sensitive individuals are particularly morally critical. Some theorists take this as evidence that disgust has a uniquely moral form: disgust contributes to moralization even of pathogen-free violations, and disgust’s contribution to moralization is unique from other emotional states. We argue that the relationship between disgust sensitivi...

A major challenge for accumulating knowledge in psychology is the variation in methods and participant populations across studies in a single domain. We offer a systematic approach to addressing this challenge and implement it in the domain of money priming. In three preregistered experiments ( N = 4,649), participants were exposed to one of a numb...

The use of performance enhancing drugs (PEDs) elicits widespread normative opposition, yet little research has investigated what underlies these judgments. We examine this question comprehensively, across 13 studies. We first test the hypothesis that opposition to PED use cannot be fully accounted for by considerations of fairness. We then test the...

I present a novel way to conceptualize Turiel and colleagues' Social Domain Theory (SDT), and Haidt and colleagues' Moral Foundations Theory (MFT), as theories of how concepts of moral violations are mentally represented. I argue that SDT is best viewed as a theory of the features that are associated with concepts of moral violations, including wro...

Morality, sociability, and competence are distinct dimensions in person perception. We argue that a person’s morality informs us about their likely intentions, whereas their competence and sociability inform us about the likelihood that they will fulfill those intentions. Accordingly, we hypothesized that whereas morality would be considered uncond...

Forthcoming book chapter on moral character

This research explores the structure of social cognitive judgments and the role of moral evaluations in everyday social cognition. In Chapter 1, I show that morality and sociability are distinct dimensions in lay theories of personality and stereotype content, contrary to dominant two-dimensional models of social cognition that consider these to be...

The CAD triad hypothesis (Rozin, Lowery, Imada, & Haidt, 1999) stipulates that, cross-culturally, people feel anger for violations of autonomy, contempt for violations of community, and disgust for violations of divinity. Although the disgust-divinity link has received some measure of empirical support, the results have been difficult to interpret...

Recent research has shown that religious individuals are much more resistant to utilitarian modes of thinking than their less religious counterparts, but the reason for this is not clear. We propose that a meta-ethical belief that morality is rooted in inviolable divine commands (i.e., endorsement of Divine Command Theory) may help explain this fin...
