It has been proposed that somatosensory reaction to varied social circumstances results in feelings (i.e., conscious emotional experiences). Here, we present two preregistered studies in which we examined the topographical maps of somatosensory reactions associated with violations of different moral concerns. Specifically, participants in Study 1 (...

Most moral psychology research has been conducted in Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. As such, moral judgment, as a psychological phenomenon, might be known to researchers only by its WEIRD manifestations. Here, we start with evaluating Moral Foundations Theory (MFT) using the Moral Foundations Questionnair...

Most of the empirical research on sex differences and cultural variations in morality has relied on within-culture analyses or small-scale cross-cultural data. To further broaden the scientific understanding of sex differences in morality, the current research relies on two international samples to provide the first large-scale examination of sex d...

Online radicalization is among the most vexing challenges the world faces today. Here, we demonstrate that homogeneity in moral concerns results in increased levels of radical intentions. In Study 1, we find that in Gab—a right-wing extremist network—the degree of moral convergence within a cluster predicts the number of hate-speech messages member...

A growing body of evidence suggests that many aspects of psychology have evolved culturally over historical time. A combination of approaches, including experimental data collected over the last 75 years, cross-cultural comparisons and studies of immigrants, points to systematic changes in psychological domains as diverse as conformity, attention,...

Prejudice between regional, ethnic, religious, familial, and class groups is a fixture of modern societies, but we still know little about how prejudice unfolded across human history. By some accounts, prejudice is a human universal. By others, it should vary based on ecology or social structure. We present two mixed-method historical analyses show...

Honor requires that individuals demonstrate their worth in the eyes of others. However, it is unclear how honor and its implications for behavior vary between societies. Here, we explore the tension between competing views about how to make sense of honor–as narrowly defined through self-reliance and self-defense or as broadly defined through stren...

The emergence of large language models (LLMs) has sparked considerable interest in their potential application in psychological research, mainly as a model of the human psyche or as a general text-analysis tool. However, the trend of using LLMs without sufficient attention to their limitations and risks, which we rhetorically refer to as “GPTology”...

Psychology is a young science. Its definition and scope have shifted over the discipline’s short history. Here, we call for psychology to become a historical and geographical science. We list four underlying reasons as to why such a transformation, a chronospatial revolution, has yet to take off: problems in data, scope, synergy, and theory. We dis...

We investigated the universality versus cultural specificity of preferences for internal decision-making strategies (intuition or deliberation) over external strategies (advice from friends or crowds). Participants from diverse samples spanning five continents (N=3,517), including Indigenous communities, were presented with scenarios involving choo...

Groups can be diverse along many dimensions like gender, race, and national background. These forms of (demographic) diversity are celebrated by many and well-studied in social sciences. Much less is known, however, about moral diversity — the presence of people with different moral priorities in a group. Here, we argue that increased moral diversi...

The emergence of large language models (LLMs) has sparked considerable interest in their potential application in psychological research, either as a human-like entity used as a model for the human psyche or as a general text-analysis tool. However, carelessly using LLMs in psychological studies, a trend we rhetorically refer to as “GPTology,” can...

Boyer presents a compelling account of ownership as the outcome of interaction between two evolved cognitive systems. We integrate this model into current discussions of moral pluralism, suggesting that ownership meets the criteria to be a moral foundation. We caution against ignoring cultural variation in ownership norms and against explaining com...

This account of puritanical morality is useful and innovative, but makes two errors. First, it mischaracterizes the purity foundation as being unrelated to cooperation. Second, it makes the leap from cooperation (broadly construed) to a monist account of moral cognition (as harm or fairness). We show how this leap is both conceptually incoherent an...

Large language models (LLMs) have recently made vast advances in both generating and analyzing textual data. Technical reports often compare LLMs’ outputs with “human” performance on various tests. Here, we ask, “Which humans?” Much of the existing literature largely ignores the fact that humans are a cultural species with substantial psychological...

Moral foundations theory has been a generative framework in moral psychology in the last 2 decades. Here, we revisit the theory and develop a new measurement tool, the Moral Foundations Questionnaire–2 (MFQ-2), based on data from 25 populations. We demonstrate empirically that equality and proportionality are distinct moral foundations while retain...

Humans use language toward hateful ends, inciting violence and genocide, intimidating and denigrating others based on their identity. Despite efforts to better address the language of hate in the public sphere, the psychological processes involved in hateful language remain unclear. In this work, we hypothesize that morality and hate are concomitan...

Given its centrality in scholarly and popular discourse, morality should be expected to figure prominently in everyday talk. We test this expectation by examining the frequency of moral content in three contexts, using three methods: (a) Participants’ subjective frequency estimates (N = 581); (b) Human content analysis of unobtrusively recorded in-...

A growing body of evidence suggests that many aspects of psychology have evolved culturally over historical time. A combination of approaches, including experimental data collected over the past 75 years, cross-cultural comparisons, and studies of immigrants, points to systematic changes in psychological domains as diverse as conformity, attention,...

Social stereotypes negatively impact individuals’ judgments about different groups and may have a critical role in understanding language directed toward marginalized groups. Here, we assess the role of social stereotypes in the automated detection of hate speech in the English language by examining the impact of social stereotypes on annotation be...

Over the past decades, text-analysis methods have been slowly integrated into the toolbox of methods used to reliably measure psychological constructs. Yet, many of the existing computational methods in psychological text analysis remain atheoretical and lack the interpretability that social sciences are accustomed to and desire. Here, we introduce...

Online social-media platforms are a vital arena in which socio-political perspectives are put forth, debated, and spread. Prior work suggests that certain moral-emotional language drives online contagion, but theoretical and empirical findings remain debated, inhibiting constructive interventions. We substantially advance this ongoing debate using...

Existing word embedding debiasing methods require social-group-specific word pairs (e.g., "man"-"woman") for each social attribute (e.g., gender), which cannot be used to mitigate bias for other social groups, making these methods impractical or costly to incorporate understudied social groups in debiasing. We propose that the Stereotype Content Mo...

Humans use language toward hateful ends, inciting violence and genocide, intimidating and denigrating others based on their identity. Despite efforts to better address the language of hate in the public sphere, the psychological processes underlying the development of hate remain unclear. In this work, we hypothesize that morality and hate are conc...

Despite the widespread availability of COVID-19 vaccines, the United States has a depressed rate of vaccination relative to similar countries. Understanding the psychology of vaccine refusal, particularly the possible sources of variation in vaccine resistance across U.S. subpopulations, can aid in designing effective intervention strategies to inc...

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in t...

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about...

Infectious diseases have been an impending threat to the survival of individuals and groups throughout our evolutionary history. As a result, humans have developed psychological pathogen-avoidance mechanisms and groups have developed societal norms that respond to the presence of disease-causing microorganisms in the environment. In this work, we d...

Significance Communicating in ways that motivate engagement in social distancing remains a critical global public health priority during the COVID-19 pandemic. This study tested motivational qualities of messages about social distancing (those that promoted choice and agency vs. those that were forceful and shaming) in 25,718 people in 89 countries...

We present the Gab Hate Corpus (GHC), consisting of 27,665 posts from the social network service gab.com, each annotated for the presence of “hate-based rhetoric” by a minimum of three annotators. Posts were labeled according to a coding typology derived from a synthesis of hate speech definitions across legal precedent, previous hate speech coding...

We tested the prediction that how people respond to all-encompassing life difficulties that may require taking on novel difficult tasks or goals is a function of what they infer about their identities from these experiences of difficulty. We focused on the COVID-19 pandemic and identity-based motivation theory to test our predictions (N=698 U.S. ad...

Cultures often provide deservingness and authority-based narratives to explain the difficulties people experience in life. Accepting these narratives is culturally fluent but can be depleting. We predicted and showed that people often also interpret their life difficulties as opportunities for self-growth— a difficulty-as-improvement mindset. Our c...

Social stereotypes negatively impact individuals' judgements about different groups and may have a critical role in how people understand language directed toward minority social groups. Here, we assess the role of social stereotypes in the automated detection of hateful language by examining the relation between individual annotator biases and err...

In everyday language, abstract concepts are described in terms of concrete physical experiences (e.g., good things are “up”; the past is “behind” us). Stimuli congruent with such conceptual metaphors are processed faster than stimuli that are not. Since ease of processing enhances aesthetic pleasure, stimuli should be perceived as more pleasing whe...

Despite the widespread availability of COVID-19 vaccines, the United States has a depressed rate of vaccination as of September 2021.

Bias mitigation approaches reduce models' dependence on sensitive features of data, such as social group tokens (SGTs), resulting in equal predictions across the sensitive features. In hate speech detection, however, equalizing model predictions may ignore important differences among targeted social groups, as hate speech can contain stereotypical...

Understanding motivations underlying acts of hatred are essential for developing strategies to prevent such extreme behavioral expressions of prejudice (EBEPs) against marginalized groups. In this work, we investigate the motivations underlying EBEPs as a function of moral values. Specifically, we propose EBEPs may often be best understood as moral...

Language is a psychologically rich medium for human expression and communication. While language usage has been shown to be a window into various aspects of people's social worlds, including their personality traits and everyday environment, its correspondence to people's moral concerns has yet to be considered. Here, we examine the relationship be...

Effectively motivating social distancing—keeping a physical distance from others —has become a global public health priority during the COVID-19 pandemic. This cross-country preregistered experiment (n=25,718 in 89 countries) tested hypotheses derived from self-determination theory concerning generalizable positive and negative outcomes of differen...

During the COVID-19 pandemic, people differed in the extent to which they took matters into their own hands rather than follow COVID-19-related public health guidelines. In the current paper, we take a culture-as-situated cognition perspective to suggest that one reason for this variability may be that the pandemic triggered honor concerns. Honor i...

Approaches for mitigating bias in supervised models are designed to reduce models' dependence on specific sensitive features of the input data, e.g., mentioned social groups. However, in the case of hate speech detection, it is not always desirable to equalize the effects of social groups because of their essential role in distinguishing outgroup-d...

Language is a psychologically rich medium for human expression and communication. While it is often used in moral psychology as an intermediary between researcher and participant, much of the human experience that occurs through language — our relationships, conversations, and, in general, the everyday transmission of our thoughts — has yet to be s...

The growing prominence of online hate speech is a threat to a safe and just society. This endangering phenomenon requires collaboration across the sciences in order to generate evidence-based knowledge of, and policies for, the dissemination of hatred in online spaces. To foster such collaborations, here we present the Gab Hate Corpus (GHC), consis...

Research has shown that accounting for moral sentiment in natural language can yield insight into a variety of on- and off-line phenomena such as message diffusion, protest dynamics, and social distancing. However, measuring moral sentiment in natural language is challenging, and the difficulty of this task is exacerbated by the limited availabilit...

The Breast Size Satisfaction Survey (BSSS) was established to assess women’s breast size dissatisfaction and breasted experiences from a cross-national perspective. A total of 18,541 women were recruited from 61 research sites across 40 nations and completed measures of current-ideal breast size discrepancy, as well as measures of theorised anteced...

Cross-cultural research on long-term mate preferences in Muslim-majority countries is scarce.

Acts of hate have been used to silence, terrorize, and erase marginalized social groups throughout history. The rising rates of these behaviors in recent years underscores the importance of developing a better understanding of when, why, and where they occur. In this work, we present a program of research that suggests that acts of hate may often b...

Several self-report measures of conspiracist beliefs have been developed in Western populations, but examination of their psychometric properties outside Europe and North America is limited. This study aimed to examine the psychometric properties of three widely-used measures of conspiracist beliefs in Iran. We translated the Belief in Conspiracy T...

Previous research indicates that the romantic attachment dimensions of anxiety and avoidance are associated with performance frequency of Benefit-Provisioning and Cost-Inflicting domains of mate retention. The current research aimed to replicate previous findings in a non-Western sample (Iran, Study 1), and to extend this research by investigating...

Scientists have shown growing interest in the psychology of aesthetic experience. Aesthetic fluency is one of the most promising variables to assess knowledge-based familiarity with a number of terms and artists in art history. However, there is little information regarding the structure of the aesthetic fluency and its personality and individual d...

A large number of studies have investigated body image and appearance-related social comparisons among college students and adolescents. However, there is no adolescent-specific instrument for measurement of body and appearance satisfaction within social context. The present study aimed to develop and validate Adolescent Comparative Body and Appear...

Individuals perform mate retention behaviors to minimize the risk of partner infidelity and relationship dissolution. The current study investigates whether consideration of cosmetic surgery can be conceptualized as part of a broader strategy of mate retention for women, but not men. We hypothesized that women’s consideration of cosmetic surgery wo...

Perfectionism as a personality trait has a multidimensional nature. Providing a new multidimensional measure of perfectionism, Smith, Saklofske, Stoeber, and Sherry (2016) developed the Big Three Perfectionism Scale (BTPS). The BTPS has shown very good psychometric properties, yet has not been subjected to psychometric analyses across cultures. The...

The present research aimed to examine the psychometric properties of the Self-Rating of Religiosity (SRR) in Iran. In addition, the associations between the Persian version of this single-item measure of religiosity and the Big Five personality dimensions were investigated. Study 1 (n = 51) suggested that the Persian translation of the SRR had adeq...

Objective: This study aimed to investigate the associations between perfectionism cognitions, religiosity and the desired number of children in young women. Background: The desired number of children has been found to correlate with personality and individual difference. Methods: A sample of 281 women was selected from university settings in Tehran...
