Stereotypes as Bayesian prediction of social groups

A stereotype is a generalization about a class of people which is often used to make probabilistic predictions about individuals within that class. Can stereotypes can be understood as conditional probabilities that distinguish among groups in ways that follow Bayesian posterior prediction? For instance, the stereotype of Germans as industrious can be understood as the conditional probability of someone being industrious given that they are German. Whether such representations follow Bayes' rule was tested in a replication and extension of past work. Across three studies (N = 2,652), we found that people's judgments of different social categories were appropriately Bayesian, in that their direct posterior predictions were aligned with what Bayes' rule suggests they should be. Moreover, across social categories, traits with a high calculated diagnostic ratio generally distinguished stereotypic from non-stereotypic traits. The effects of cognitive ability, political orientation, and motivated stereotyping were also explored.

Using Monte Carlo Simulation to Forecast the Scientific Utility of Psychological App Studies: A Tutorial

Mobile applications offer a wide range of opportunities for psychological data collection, such as increased ecological validity and greater acceptance by participants compared to traditional laboratory studies. However, app-based psychological data also pose data-analytic challenges because of the complexities introduced by missingness and interdependence of observations. Consequently, researchers must weigh the advantages and disadvantages of app-based data collection to decide on the scientific utility of their proposed app study. For instance, some studies might only be worthwhile if they provide adequate statistical power. However, the complexity of app data forestalls the use of simple analytic formulas to estimate properties such as power. In this paper, we demonstrate how Monte Carlo simulations can be used to investigate the impact of app usage behavior on the utility of app-based psychological data. We introduce a set of questions to guide simulation implementation and showcase how we answered them for the simulation in the context of the guessing game app Who Knows (Rau et al., 2023). Finally, we give a brief overview of the simulation results and the conclusions we have drawn from them for real-world data generation. Our results can serve as an example of how to use a simulation approach for planning real-world app-based data collection.

Job Type, Religion, and Muslim Gender as Predictors of Discrimination in Employment Settings

Most employment discrimination research has focused on race and gender. The relatively fewer papers dealing with religion suggests that discrimination exists. We extend the literature by examining the effects of job type (public safety/non-public safety), religion (Muslim/non-Muslim) and Muslim gender on selection decisions. Participants ranked applicants and made judgments on trust and whether to interview applicants after evaluating seven resumes for either a shipping clerk or a security guard position. Participants rated Muslim applicants lower than non-Muslim applicants for the security guard position. We found no evidence of discrimination in the shipping clerk position. Perceived trust may be a possible explanation for some of the decisions people made. We also found that the Muslim female candidate was rated higher than the Muslim male candidate for the security guard position; no gender differences existed for the shipping clerk position. Our findings are consistent with the gender discrimination literature in that job type affected the extent to which religious-based discrimination occurred and the intersectionality literature/models specifying that combinations of demographics can impact judgments. One implication is the need to incorporate religion in discrimination interventions.

Valence-Dependent Implicit Action Generalization Among Group Members

People implicitly generalize the actions of known individuals in a social group to unknown members. However, actions have social goals and evaluative valences, and the extent to which actions with different valences (helpful and harmful) are implicitly generalized among group members remains unclear. We used computer animations to simulate social group actions, where helping and hindering actions were represented by aiding and obstructing another's climb up a hill. Study 1 found that helpful actions are implicitly expected to be shared among members of the same group but not among members of different groups, but no such effect was found for harmful actions. This suggests that helpful actions are more likely than harmful actions to be implicitly generalized to group members. This finding was replicated in Study 2 by increasing the group size from three to five. Study 3 found that the null effect for generalizing harmful actions among group members is not due to the difficulty of detecting action generalization, as both helpful and harmful actions are similarly generalized within particular individuals. Moreover, Study 4 demonstrated that weakening social group information resulted in the absence of implicit generalization for helpful actions, suggesting the specificity of group membership. Study 5 revealed that the generalization of helping actions occurred when actions were performed by multiple group members rather than being repeated by one group member, showing group-based inductive generalization. Overall, these findings support valence-dependent implicit action generalization among group members. This implies that people may possess different knowledge regarding valenced actions on category-based generalization.

Preliminary evidence for neck musculature in shaping functional stereotypes of men's relationship motives

Neck musculature is reliably diagnostic of men's formidability and central to several inferences of their physical prowess. These inferences facilitate stereotypes of men's social value from which perceivers estimate their abilities to satisfy reproductive goals related to mate acquisition and parental care. Participants evaluated men's interest in various mating and parenting strategies, wherein men varied in the size of visible neck musculature through trapezii and sternocleidomastoids for perceivers to identify potential reproductive interests and goals. Large trapezii elicited perceptions of men as more effective at protecting offspring, albeit at the expense of nurturance and interest in long-term pair bonds. Results extend previous findings implicating formidability as central to relationship decisions by considering a novel modality.

Conversational Silencing of Racism in Psychological Science: Toward Decolonization in Practice

This article addresses a paradox between self-perceptions of psychology as a liberal, progressive, antiracist discipline and profession and the persistent criticisms of racism and calls for decolonization. It builds on the criticisms of epistemic exclusion and White centering, arguing that White supremacy is maintained by "conversational silencing" in which the focus on doing good psychology systematically draws attention away from the realities of racism and the operation of power. The process is illustrated by investigations of disciplinary discourse around non-Western, educated, industrialized, rich, and democratic psychology and on stereotyping, racism, and prejudice reduction, which constitute the vanguard of liberal scholarship in the discipline. This progressive scholarship nurtures "White ignorance," an absence of belief about systemic racism that psychology plays a part in upholding.

Does dispositional preference for solitude predict better psychological outcomes during times of social distancing? Beliefs and reality

OBJECTIVE

People value solitude for themselves. Yet little is known about how people perceive dispositional preference for solitude in others. Does dispositional preference for solitude represent a protective factor from psychological distress during times of social distancing? And do laypeople have accurate beliefs about the role of preference for solitude?

METHOD

To answer these questions, we conducted four studies (three preregistered, Ntotal  = 1418) at the early and a later stage of the COVID-19 pandemic using experimental, longitudinal, and experience sampling designs.

RESULTS

People expected targets with a higher solitude preference to be more resilient (e.g., less lonely, more satisfied with life) during social distancing, and consequently prioritize them less when allocating supportive resources for maintaining social connections (Studies 1 and 2). Compared to these beliefs, the actual difference between individuals with higher versus lower solitude preference was smaller (Study 2) or even negligible (Study 3). Did people form more calibrated beliefs two years into the pandemic? Study 4 suggested no.

CONCLUSIONS

Together, these studies show that people overestimate the role of preference for solitude in predicting others' psychological experience. As a result, solitude-seeking individuals may miss out on supportive resources, leading to higher risks for mental health issues.

Factors that contribute to accurately perceiving anti-black racism and sexism overlap

Past research demonstrates that prejudice toward women and Black Americans often co-occur in individuals. The present studies examine factors related to accuracy in estimating the co-occurrence, or overlap, of prejudice toward women and Black Americans. Across two studies, criterion overlap percentages were computed using national datasets and separate participant samples estimated prejudice overlap. Results indicate that beliefs about the generalized nature of prejudice can improve accuracy by reducing faulty underestimation of the overlap in anti-Black racism and sexism. In addition to greater displayed accuracy in perceptions of prototypical perpetrators of prejudice (i.e., estimates of White men compared to White women), the present work suggests that accuracy is improved when estimating sexist attitudes from racist attitudes, rather than vice versa. Together, this work documents the accuracy of prejudice overlap perceptions, for the first time, and factors that facilitate accuracy (i.e., perpetrator prototypicality, known prejudicial attitude), with implications for intergroup dynamics research.

Warmer Individuals Get More Help: The Influence of Stereotypes and Empathy on Moral Decision-Making

The processing of moral decision-making is influenced by both cognitive and emotional systems, making it worth exploring exactly how each plays a role in the process of individual moral decision-making. In this study, 160 participants with either high or low empathy traits (80 each, as determined by the Interpersonal Response Index Inventory) completed a moral decision-making task regarding whether to help others (stereotyped as high warmth-high competence, high warmth-low competence, low warmth-high competence, low warmth-low competence) at the expense of themselves. The intent was to explore the influence of stereotypes and empathy traits on moral decision-making. The results showed that: (1) participants were more willing to help individuals with high warmth than those with high competence, showing a clear "primacy of warmth effect"; (2) this effect was weakened in participants with high empathy traits in comparison to those with low empathy traits, as their willingness to help individuals with low warmth was significantly higher than that of participants with low empathy traits. The results suggest that stereotypes about warmth and competence moderate altruistic tendencies in moral decision-making and that this moderation is more pronounced in individuals with low empathy traits than in those with high empathy traits.

Still No Evidence for a Jewish Group Evolutionary Strategy

I recently criticized some key tenets of what I called the “anti-Jewish narrative,” particularly as defended by Kevin MacDonald. According to MacDonald, Judaism is a “group evolutionary strategy” that led Jews to impose liberal multiculturalism on the West in order to advance their evolutionary interests at the expense of gentiles. In light of MacDonald’s reply, in this paper, I refine my previous arguments, address some popular misunderstandings, and discuss the root causes and consequences of anti-Semitism. I conclude that, contra the anti-Jewish narrative, Jews are not particularly ethnocentric, Jewish intellectuals do not typically advocate liberal multiculturalism for gentiles but not for Jews, Jews did not orchestrate the rise of liberalism or blank-slatism in the West, and anti-Semitism is not primarily a response to actual Jewish wrongdoing.

Linking gender differences with gender equality: A systematic-narrative literature review of basic skills and personality

There is controversy regarding whether gender differences are smaller or larger in societies that promote gender equality highlighting the need for an integrated analysis. This review examines literature correlating, on a national level, gender differences in basic skills-mathematics, science (including attitudes and anxiety), and reading-as well as personality, to gender equality indicators. The aim is to assess the cross-national pattern of these differences when linked to measures of gender equality and explore new explanatory variables that can shed light on this linkage. The review was based on quantitative research relating country-level measures of gender differences to gender equality composite indices and specific indicators. The findings show that the mathematics gender gap from the PISA and TIMMS assessments, is not linked to composite indices and specific indicators, but gender differences are larger in gender-equal countries for reading, mathematics attitudes, and personality (Big Five, HEXACO, Basic Human Values, and Vocational Interests). Research on science and overall scores (mathematics, science, and reading considered together) is inconclusive. It is proposed that the paradox in reading results from the interrelation between basic skills and the attempt to increase girls' mathematics abilities both acting simultaneously while the paradox in mathematics attitudes might be explained by girls being less exposed to mathematics than boys. On the other hand, a more nuanced understanding of the gender equality paradox in personality is advanced, in which a gene-environment-cultural interplay accounts for the phenomenon. Challenges for future cross-national research are discussed.

Adolescents’ implicit attitudes towards people with immigrant background: Differences and correlates

People with an immigrant background can be affected by stereotypes and discrimination. As adolescence is an important developmental stage, this study investigated whether adolescents hold (negative) implicit attitudes towards people with Turkish immigrant background and whether adolescents differ in the extent of attitudes. Additionally, the relevance of perceived discrimination, identification with culture of residence, motivation to act without predjudice, and quality and quantity of contact to people with Turkish immigrant background for the extent of implicit attitudes was analysed. Analyses are based on 244 adolescents (60.7% female, 1.6% diverse; 13.1% with Turkish immigrant background, 16.8% with immigrant background other than Turkish) who participated in an online study. An implicit association test revealed that negative implicit attitudes towards people with a Turkish immigrant background were present among adolescents. Unlike adolescents with a Turkish immigrant background, adolescents without immigrant background and with immigrant background other than Turkish hold negative implicit attitudes on average. For the total sample, it was found that low perceived discrimination was related to negative implicit attitudes. The results are discussed with respect to substantive and methodological aspects. Implications for research and practice are derived.

College Students’ Political Attitudes Affect Negative Stereotypes about Social Groups

This study examined the relations between political attitudes and negative stereotypes in undergraduates by employing 4 measures of stereotypes: modern sexism, modern racism, feelings about 20 social groups, and ratings of the intelligence of these social groups. It was hypothesized that conservatives and Republicans alike would show more evidence of negative stereotypes than liberals and Democrats, especially for disadvantaged social groups. The study revealed that, indeed, Republicans showed stronger evidence of negative stereotypes but that Democrats also harbor some biases. Importantly, the social groups for whom Democrats and Republicans show negative stereotypes differed greatly. Republicans had considerably more negative stereotypes against racial and religious minorities, and particularly against individuals who do not identify with the cis-gender, heterosexual norm. Thus, the targets of Republicans’ stereotypes were groups that have traditionally been subjected to discrimination. Democrats, on the other hand, held stronger negative stereotypes against groups that are more politically powerful, such as Caucasians and Christians.

Gender Biases in Estimation of Others' Pain

Caregiving and other interpersonal interactions often require accurate perception of others' pain from nonverbal cues, but perceivers may be subject to systematic biases based on gender, race, and other contextual factors. Such biases could contribute to systematic under-recognition and undertreatment of pain. In 2 experiments, we studied the impact of perceived patient sex on lay perceivers' pain estimates and treatment recommendations. In Experiment 1 (N = 50), perceivers viewed facial video clips of female and male patients in chronic shoulder pain and estimated patients' pain intensity. Multi-level linear modeling revealed that perceivers under-estimated female patients' pain compared with male patients, after controlling for patients' self-reported pain and pain facial expressiveness. Experiment 2 (N = 200) replicated these findings, and additionally found that 1) perceivers' pain-related gender stereotypes, specifically beliefs about typical women's vs. men's willingness to express pain, predicted pain estimation biases; and 2) perceivers judged female patients as relatively more likely to benefit from psychotherapy, whereas male patients were judged to benefit more from pain medicine. In both experiments, the gender bias effect size was on average 2.45 points on a 0-100 pain scale. Gender biases in pain estimation may be an obstacle to effective pain care, and experimental approaches to characterizing biases, such as the one we tested here, could inform the development of interventions to reduce such biases. Perspective: This study identifies a bias towards underestimation of pain in female patients, which is related to gender stereotypes. The findings suggest caregivers' or even clinicians' pain stereotypes are a potential target for intervention.

Evidence for a gender stereotype about psychology and its effect on perceptions of men's and women's fit in the field

The current research explored the gender stereotype about psychology and its effect on perceptions of people's fit in the field. Across six studies (N = 1,516), results showed that participants believed that women represent the majority of people in both the major and profession of psychology. Also, participants associated psychology more strongly with femininity than masculinity and assigned more feminine and less masculine traits to people studying psychology than to people studying a stereotypically masculine career. In terms of fit within the field, participants rated psychology as less likely to meet the needs of men compared to women, especially after learning that the field was majority women. Overall, the studies provide evidence for an association between femininity and psychology and suggest that the stereotype affects perceptions of men's and women's fit within the field.

Implizite Einstellungen von Kindern im Grundschulalter gegenüber Menschen mit Migrationshintergrund

Zusammenfassung. Erwachsene und Jugendliche ohne Migrationshintergrund (MIG) schreiben Personen mit türkischem MIG, der größten Migrationsgruppe in Deutschland, geringere Kompetenzen und Leistungen zu. Inwiefern bereits bei Kindern solche (negativen) impliziten Einstellungen gegenüber Menschen mit türkischem MIG vorliegen, ist bislang ungeklärt und wurde daher in dieser Studie überprüft. Auch wurde analysiert, ob sich Grundschulkinder mit türkischem und ohne MIG in ihren Einstellungen unterscheiden. Zudem wurde geprüft, ob die soziale Integration, die wahrgenommene Diskriminierung sowie die Identifikation mit der Aufnahme- und Herkunftskultur mit impliziten Einstellungen in Zusammenhang standen. Datengrundlage bildeten Angaben von 240 Viertklässlerinnen und -klässlern (44.6% weiblich, 18.3% mit türkischem MIG). Zur Messung impliziter Einstellungen bearbeiteten die Kinder einen Impliziten Assoziationstest. Des Weiteren beantworteten sie Fragen zu den interessierenden Variablen. Bei den Grundschulkindern lagen negative implizite Einstellungen vor ( d = 0.21). Konkret verfügten Kinder ohne MIG im Gegensatz zu Kindern mit türkischem MIG im Mittel über negative implizite Einstellungen ( d = 0.39). Für die Gesamtstichprobe zeigte sich, dass eine stärkere Identifikation mit Deutschland (ß = .14), der Aufnahmekultur, in Zusammenhang mit negativen impliziten Einstellungen stand ( R2 = .03). Die Ergebnisse werden sowohl inhaltlich als auch hinsichtlich methodischer Gesichtspunkte diskutiert. Implikationen für Forschung und Praxis werden vorgestellt.

It Is Hard to Read Minds without Words: Cues to Use to Achieve Empathic Accuracy

When faced with the task of trying to “read” a stranger’s thoughts, what cues can perceivers use? We explore two predictors of empathic accuracy (the ability to accurately infer another person’s thoughts): use of stereotypes about the target’s group, and use of the target’s own words. A sample of 326 White American undergraduate students were asked to infer the dynamic thoughts of Middle Eastern male targets, using Ickes’ (Ickes et al. 1990) empathic accuracy paradigm. We predicted use of stereotypes would reduce empathic accuracy because the stereotypes would be negative and inaccurate. However, more stereotypical inferences about the target’s thoughts actually predicted greater empathic accuracy, a pattern in line with past work on the role of stereotypes in empathic accuracy (Lewis et al. 2012), perhaps because the stereotypes of Middle Easterners (collected from a sample of 60 participants drawn from the same population) were less negative than expected. In addition, perceivers who inferred that the targets were thinking thoughts that more closely matched what the target was saying out loud were more empathically accurate. Despite the fact that words can be used intentionally to obscure what a target is thinking, they appear to be a useful cue to empathic accuracy, even in tricky contexts that cross cultural lines.

Personal Value Preferences, Threat-Benefit Appraisal of Immigrants and Levels of Social Contact: Looking Through the Lens of the Stereotype Content Model

The study examines a model proposing relationships between personal values, positive (i.e., benefits) and negative (i.e., threats) appraisal of immigrants, and social contact. Based on a values-attitudes-behavior paradigm, the study extends previous work on personal values and attitudes to immigrants by examining not only negative but also positive appraisal and their connection with social contact with immigrants. Using a representative sample of 1,600 adults in the majority population in Israel, results showed that higher preference for anxiety-avoidance values (self-enhancement and conservation) was related to higher levels of perceived threat and lower levels of benefit, while higher preference for anxiety-free values (self-transcendence and openness to change) was related to higher levels of perceived benefits and lower levels of threat. Greater opportunities for contact and perceived benefits and lower levels of threats were related to more social contact. The model showed good fit across the total sample, and across four diverse immigrant groups in Israel (diaspora immigrants from the Former Soviet Union, Ethiopia and Western countries, and asylum seekers). In line with a Stereotype Content Model, which suggests that group-specific stereotypes are related to social structural characteristics of the group, associations between variables differed by group. Results strengthen a theoretical conceptualization that posits an indirect relationship between personal value preferences and behavior through group appraisal. They highlight the importance of comprehensive conceptualizations including both positive and negative appraisal of immigrants, which take into account the way different groups may be appraised by the majority population.

How Refugees' Stereotypes Toward Host Society Members Predict Acculturation Orientations: The Role of Perceived Discrimination

Refugee migration leads to increased diversity in host societies and refugees have to face many stereotyped attitudes in the host society. However, there has been little research on minority group stereotypes toward host society members and how these stereotypes relate to the acculturation-relevant attitudes of refugees in their first phase of acculturation. This study surveyed 783 refugees in Germany who had migrated mostly in the so-called "refugee crisis" between 2015 and 2016. At the time of the survey in 2018, they had been in Germany for an average of 27 months (SD = 15 months). These refugees reported their positive and negative sociability stereotypes toward German host society members, acculturation-related orientations, shared reality values, and perceived discrimination. Results showed that positive sociability stereotypes toward host society members were associated with increased cultural adoption and shared reality. In contrast, negative sociability stereotypes negatively affected cultural adoption and shared reality. However, stereotypes showed no association at all with cultural maintenance. Interactions between sociability stereotypes and discrimination experiences highlighted a disillusion effect, in the sense that discrimination reduced the motivation to adopt the host culture more strongly among refugees who held strongly positive sociability stereotypes. The study extends knowledge on the significance of minority group stereotypes in the context of refugee migration and reveals the maladaptive consequences of discriminatory behavior against refugees by host society members.

What Can Experimental Studies of Bias Tell Us About Real-World Group Disparities?

This article questions the widespread use of experimental social psychology to understand real-world group disparities. Standard experimental practice is to design studies in which participants make judgments of targets who vary only on the social categories to which they belong. This is typically done under simplified decision landscapes and with untrained decision makers. For example, to understand racial disparities in police shootings, researchers show pictures of armed and unarmed Black and White men to undergraduates and have them press "shoot" and "don't shoot" buttons. Having demonstrated categorical bias under these conditions, researchers then use such findings to claim that real-world disparities are also due to decision-maker bias. I describe three flaws inherent in this approach, flaws which undermine any direct contribution of experimental studies to explaining group disparities. First, the decision landscapes used in experimental studies lack crucial components present in actual decisions (Missing Information Flaw). Second, categorical effects in experimental studies are not interpreted in light of other effects on outcomes, including behavioral differences across groups (Missing Forces Flaw). Third, there is no systematic testing of whether the contingencies required to produce experimental effects are present in real-world decisions (Missing Contingencies Flaw). I apply this analysis to three research topics to illustrate the scope of the problem. I discuss how this research tradition has skewed our understanding of the human mind within and beyond the discipline and how results from experimental studies of bias are generally misunderstood. I conclude by arguing that the current research tradition should be abandoned.

Is there evidence for statistical discrimination against ethnic minorities in hiring? Evidence from a cross-national field experiment

While statistical discrimination theory is often proposed as an important explanation for ethnic discrimination in hiring, research that empirically scrutinizes its underlying assumptions is scant. To test these assumptions, we combine data from a cross-national field experiment with secondary data indicative of the average labor productivity of ethnic communities. We find little evidence that adding diagnostic personal information reduces discrimination against ethnic minorities. Furthermore, we do not find an association between language similarity or the socioeconomic resources of the ethnic community and hiring discrimination. However, our findings show that discrimination is related to the socioeconomic development of the country of ancestry. Finally, the impact of these indicators of group productivity is generally not moderated by the amount of diagnostic personal information. Taken together, these findings question several core assumptions of statistical discrimination theory.

Individual Differences in Miserly Thinking Predict Endorsement of Racial/Ethnic Stereotypes

The “cognitive miser” metaphor is a classic characterization of mental life wherein cognitive efficiency is favored over careful and reflective thinking. A presumed implication is that reliance on intuitive processing in the absence of reflective thinking should encourage stereotyping. However, research to date has not adequately tested whether proclivities to engage reflective thinking correspond with less stereotype endorsement, nor if their influence occurs independent of cognitive ability and epistemic motivation. In two studies, we conducted straightforward tests of this hypothesis by measuring individual differences in miserly or reflective thinking, cognitive ability, and epistemic motivation as unique predictors of stereotype endorsement. We utilized objective, performance-based measures of reflective thinking via the Cognitive Reflection Test. The results provide the first direct evidence for the cognitive miser hypothesis. Individual differences in miserly thinking predicted endorsements of racial/ethnic stereotypes independent of cognitive ability and epistemic motivation.

Crazy Rich Chinese? A Mixed-Methods Examination of Perceived Stereotypes and Associated Psychosocial Adaptation Challenges among Chinese International Students in the United States

BACKGROUND

Prior research observes associations between race-based stressors (e.g. stereotypes) and the compromised psychological and sociocultural adaptation of international students.

METHODS

Using an explanatory sequential mixed-methods design (196 survey responses and 51 in-depth interviews), this study examined stereotypes perceived by Chinese students arriving on US college campuses after 2010, their interpretations of the new stereotypes, and the associated psychosocial adaptation challenges they had to navigate.

RESULTS

Our findings suggested multiple dimensions of the stereotypes this recent wave of Chinese students perceived from their American peers, including stereotypes pertinent to their financial background (frequency effect sizes = 37.6% and 51% for quantitative and qualitative results, respectively), academic abilities (20.1% and 13.7%), personality characteristics (16.5% and 19.6%), and social attitudes and behaviors (12.9% and 9.8%). Further, this study observed that the new, prevalent stereotypes (e.g. being wealthy) might foster intergroup tension and pit Chinese students against their American peers and that some Chinese students experienced psychological issues (e.g. lower levels of collective self-esteem and feelings of shame) due to the stereotypes of wealth-flaunting Chinese students.

CONCLUSIONS

This study contributes uniquely to the literature by unpacking the new stereotypes using a mixed-methods design and points to important practical implications for university services.

Reactions to male-favouring versus female-favouring sex differences: A pre-registered experiment and Southeast Asian replication

Two studies investigated (1) how people react to research describing a sex difference, depending on whether that difference favours males or females, and (2) how accurately people can predict how the average man and woman will react. In Study 1, Western participants (N = 492) viewed a fictional popular-science article describing either a male-favouring or a female-favouring sex difference (i.e., men/women draw better; women/men lie more). Both sexes reacted less positively to the male-favouring differences, judging the findings to be less important, less credible, and more offensive, harmful, and upsetting. Participants predicted that the average man and woman would react more positively to sex differences favouring their own sex. This was true of the average woman, although the level of own-sex favouritism was lower than participants predicted. It was not true, however, of the average man, who - like the average woman - reacted more positively to the female-favouring differences. Study 2 replicated these findings in a Southeast Asian sample (N = 336). Our results are consistent with the idea that both sexes are more protective of women than men, but that both exaggerate the level of same-sex favouritism within each sex - a misconception that could potentially harm relations between the sexes.

Global sex differences in personality: Replication with an open online dataset

OBJECTIVE

Sex differences in personality are a matter of continuing debate. In a study on the United States standardization sample of Cattell's 16PF (fifth edition), Del Giudice and colleagues (2012; PLoS ONE, 7, e29265) estimated global sex differences in personality with multigroup covariance and mean structure analysis. The study found a surprisingly large multivariate effect, D = 2.71. Here we replicated the original analysis with an open online dataset employing an equivalent version of the 16PF.

METHOD

We closely replicated the original MG-MCSA analysis on N = 21,567 U.S. participants (63% females, age 16-90); for robustness, we also analyzed N = 31,637 participants across English-speaking countries (61% females, age 16-90).

RESULTS

The size of global sex differences was D = 2.06 in the United States and D = 2.10 across English-speaking countries. Parcel-allocation variability analysis showed that results were robust to changes in parceling (U.S.: median D = 2.09, IQR [1.89, 2.37]; English-speaking countries: median D = 2.17, IQR [1.98, 2.47]).

CONCLUSIONS

Our results corroborate the original study (with a comparable if somewhat smaller effect size) and provide new information on the impact of parcel allocation. We discuss the implications of these and similar findings for the psychology of sex differences.

Are Danes’ Immigration Policy Preferences Based on Accurate Stereotypes?

Stereotypes about 32 country-of-origin groups were measured using an online survey of the adult, non-elderly Danish population (n = 476 after quality control). Participants were asked to estimate each group’s net fiscal contribution in Denmark. These estimates were then compared to the actual net fiscal contributions for the 32 groups, taken from a report by the Danish Ministry of Finance. Stereotypes were found to be highly accurate, both at the aggregate level (r = 0.81) and at the individual level (median r = 0.62). Interestingly, participants over- rather than underestimated the net fiscal contributions of groups from countries with a higher percentage of Muslims. Indeed, this was true at both the aggregate and individual levels (r = −0.25 and median r = −0.49, respectively). Participants were also asked to say how many immigrants from each group should be admitted to Denmark. There was a very strong correlation between participants’ aggregate immigration policy preferences and their estimates of the 32 groups’ fiscal contributions (r = 0.98), suggesting that their preferences partly reflect accurate stereotypes. Most of the analyses were pre-registered.

Accuracy of consensual stereotypes in moral foundations: A gender analysis

The current study explored the accuracy of consensual moral stereotypes that women and men hold about each other, as well as whether the gender differences in morality found in previous literature replicate on a sample of Pakistani individuals. A sample of 300 was used with an equal number of men and women. Data from 50 of the respondents was collected online, whereas the rest was collected in person from universities. The 30-item Moral Foundations Questionnaire (MFQ30) was used as a measure of five Moral Foundations, which are the basic elements of moral psychology as posited by Moral Foundations Theory. Men and women answered the questionnaire for themselves and then a second time, according to their perception of how a typical member of the other gender would respond which gave a measure of their stereotype. Comparison of actual scores of men and women revealed a statistically significant difference where women scored higher than men on the Harm foundation (p = 0.001). All other foundations, except for the Authority foundation showed the same pattern of differences as the previous literature, although they did not reach statistical significance. Stereotypes about men held by women were inaccurate underestimations on the Harm and Fairness foundations. The stereotype about women, held by men, was accurate on the Fairness foundation and inaccurate on the Authority foundation in the direction of underestimation. This research serves to further the study of Moral Foundations Theory as well as exploring the reasons behind the inaccurate moral stereotypes that men and women hold about each other, and actual gender differences in morality.

Toleration and prejudice-reduction: Two ways of improving intergroup relations

While a large body of social psychological research has shed light on the nature of prejudice and how to reduce it, we argue that such work does not address situations of cultural or religious outgroup beliefs and practices that are considered incompatible with one's own. The present theoretical article contrasts a prejudice-reduction approach with a toleration-based approach to consider the differences each have with regard to the attitude object they focus upon, the perceived reasonableness of the attitude, and the behavioral consequences each may lead to. In doing so, we consider the psychological processes involved in whether the negative attitude leads to negative actions. We conclude by arguing that a toleration-based approach forms an important addition to the psychological thinking about cultural diversity and intergroup relations. Collectively, the present work makes a novel contribution to the social psychological literature by stimulating theory development and raising novel questions for empirical research.

Trait knowledge forms a common structure across social cognition

Researchers have noted the resemblance across core models of social cognition, in which trait inferences centre on others' intentions and abilities (for example, warmth, competence). Current views posit that this common 'trait space' originates from the adaptive utility of the dimensions, predicting a relatively fixed and universal architecture. In contrast, we hypothesize that perceivers learn conceptual knowledge of how traits correlate, which shapes trait inferences similarly across domains (for example, faces, person knowledge, stereotypes), from which a common trait space emerges. Here we show substantial overlap between the structures of perceivers' conceptual and social perceptual trait spaces, across perceptual domains (studies 1-4) and that conceptual associations directly shape trait space (study 5). Furthermore, we find evidence that conceptual trait space is learned from social perception and actual personality structure (studies 6 and 7). Our findings suggest conceptual trait associations serve as a cornerstone in social perception, providing broad implications for the study of social behaviour.

Perpetrator Religion and Perceiver’s Political Ideology Affect Processing and Communication of Media Reports of Violence

Abstract. People’s interpretations of media reports about crimes may be biased by their motivations to construct and protect their worldviews and, relatedly, by criminals’ group membership. Two large-scale experiments ( Ns = 248 and 1,115) investigated how American adults interpret reports of crimes committed by either a Christian or Muslim, and how these interpretations depend on political ideology. Results show liberals attributing crimes more to religion for Christian rather than Muslim offenders, with the opposite effect for conservatives. Importantly, these biases also influenced how people communicated the news report to others. Additionally, evidence suggests that attitudes toward Islam and not toward Muslims may explain these effects. Implications for how political ideology affects interpretation and communication of media portrayals of Muslims are discussed.

The Flywheel Effect of Gender Role Expectations in Diverse Work Groups

Popular press suggests that gender diversity benefits the performance of work groups. However, decades of research indicate that such performance benefits of gender diversity are anything but a given. To account for this incongruity, in this conceptual paper we argue that the performance of gender-diverse work groups is often inhibited by self-reinforcing gender role expectations. We use the analogy of a flywheel to illustrate how gender role expectations tend to reinforce themselves via three mechanisms. Specifically, we argue that gender role expectations shape (1) the allocation of jobs, tasks, and responsibilities, (2) the behavior of perceivers, and (3) the behavior of target women and men. In turn, these three consequences of gender role expectations tend to confirm the initial gender role expectations, thus creating an automatic, self-reinforcing flywheel effect. Such self-reinforcing gender role expectations provide superficial impressions of individual women’s and men’s actual knowledge and abilities at best. We therefore further propose that each of the three mechanisms of the flywheel of gender role expectations negatively affects group performance to the extent that gender role expectations inaccurately capture group members’ actual knowledge and abilities. Because the extent to which work group members rely on gender role expectations depends on how they form impressions of others, we propose that individuals’ motivation to form accurate impressions is crucial for inhibiting the flywheel of gender role expectations. We close by advancing an agenda for future research on each of the three areas of interest in our conceptual analysis: the flywheel effect of gender role expectations, the consequences of this flywheel effect for group functioning, and ways to motivate group members to form accurate impressions.

Thought as a determinant of political opinion

Recent political events around the world, including the apparently sudden rise of populism and decline of democratic zeal, have surprised many of us and offered a window onto how people form beliefs and attitudes about the wider world. Cognitive scientists have tended to view belief and attitude formation from one of three perspectives: as a process of deliberative reasoning, as a gut reaction modulated by feelings, or as a cultural phenomenon grounded in partisan relationships. This special issue on the cognitive science of political thought brings a variety of voices to bear on the issue. The upshot is that each perspective captures part of the dynamics of opinion change, but the underlying processes operate in an integrated way. Individuals' affective reactions are conditioned by the social world, and therefore reflect their community norms. They often precede processes of reasoning, but not always. In turn, reasoning is generally motivated in the service of transmitting beliefs acquired from citizens' communities of belief. Cognition is largely a filter for attending to and sharing community norms.

Racial Bias in Perceptions of Size and Strength: The Impact of Stereotypes and Group Differences

Recent research has shown that race can influence perceptions of men’s size and strength. Across two studies (Study 1: N = 1,032, Study 2: N = 303) examining men and women from multiple racial groups (Asian, Black, and White adults), we found that although race does impact judgments of size and strength, raters’ judgments primarily track targets’ objective physical features. In some cases, racial stereotypes actually improved group-level accuracy, as these stereotypes aligned with racial-group differences in size and strength according to nationally representative data. We conclude that individuals primarily rely on individuating information when making physical judgments but do not completely discount racial stereotypes, which reflect a combination of real group-level differences and culturally transmitted beliefs.

National character stereotypes mirror language use: A study of Canadian and American tweets

National character stereotypes, or beliefs about the personality characteristics of the members of a nation, present a paradox. Such stereotypes have been argued to not be grounded in the actual personality traits of members of nations, yet they are also prolific and reliable. Stereotypes of Canadians and Americans exemplify the paradox; people in both nations strongly believe that the personality profiles of typical Canadians and Americans diverge, yet aggregated self-reports of personality profiles of Canadians and Americans show no reliable differences. We present evidence that the linguistic behavior of nations mirrors national character stereotypes. Utilizing 40 million tweets from the microblogging platform Twitter, in Study 1A we quantify the words and emojis diagnostic of Canadians and Americans. In Study 1B we explore the positivity of national language use. In Studies 2A and 2B, we present the 120 most nationally diagnostic words and emojis of each nation to naive participants, and ask them to assess personality of a hypothetical person who uses either diagnostically Canadian or American words and emojis. Personality profiles derived from the diagnostic words of each nation bear close resemblance to national character stereotypes. We therefore propose that national character stereotypes may be partially grounded in the collective linguistic behaviour of nations.

"Do I Sound Straight?": Acoustic Correlates of Actual and Perceived Sexual Orientation and Masculinity/Femininity in Men's Speech

PURPOSE

This study aims to give an integrative answer on which speech stereotypes exist toward German gay and straight men, whether and how acoustic correlates of actual and perceived sexual orientation are connected, and how this relates to masculinity/femininity. Hence, it tests speech stereotype accuracy in the context of sexual orientation.

METHOD

Twenty-five gay and 26 straight German speakers provided data for a fine-grained psychological self-assessment (e.g., masculinity/femininity) and explicit speech stereotypes. They were recorded for an extensive set of read and spontaneous speech samples using microphones and nasometry. Recordings were analyzed for a variety of acoustic parameters (e.g., fundamental frequency and nasalance). Seventy-four listeners categorized speakers as gay or straight on the basis of the same sentence.

RESULTS

Most relevant explicitly expressed speech stereotypes encompass voice pitch, nasality, chromaticity, and smoothness. Demonstrating implicit stereotypes, speakers were perceived as sounding straighter, the lower their median f0, center of gravity in /s/, and mean F2. However, based on actual sexual orientation, straight men only showed lower mean F1 than gay men. Additionally, we found evidence that actual masculinity/femininity and the degree of sexual orientation were reflected in gay and straight men's speech.

CONCLUSION

Implicit and explicit speech stereotypes about gay and straight men do not contain a kernel of truth, and differences within groups are more important than differences between them.

The Reputational Consequences of Generalized Trust

The present research examines the reputational consequences of generalized trust. High-trust individuals are seen as moral and sociable, but not necessarily competent. When controlling for other traits, there is a negative relationship between trust and perceived competence (Studies 1 and 2). Compared with optimism, generalized trust has stronger effects on morality and sociability (Study 2). Furthermore, people judge those who do not discriminate between trustworthy and untrustworthy groups (unconditional trustors) more negatively than those who only trust groups that are, in fact, trustworthy (conditional trustors). Unconditional trust and unconditional distrust are both viewed negatively (Study 3), even after controlling for attitudinal similarity (Study 4). Critically, both generalized trust and discriminant ability (i.e., conditional trust) have independent reputational benefits (Study 5). These studies suggest that generalized trust plays an important role in how we perceive and judge others.
