Depolarized by the Media? The Role of Heterogeneous and Homogeneous Traditional and Digital Media Diets in Issue Polarization Around COVID-19 in the United States

Research suggests that a heterogeneous media diet can foster more objective information evaluations, reducing issue polarization as a result. These findings beg the question: Can increased news heterogeneity reduce issue polarization around COVID-19? Using data from a cross-sectional survey in the United States (N = 1,262), this study found that - in line with theoretical expectations - at high levels of homogeneity of traditional and digital news consumption, the difference in support for COVID-19 prevention between Biden and Trump supporters was significantly large. Conversely, this attitude gap narrowed at high news heterogeneity levels. Our results continue to advance research on the role of homogeneous and heterogeneous media diets and biased cognitive processing in issue polarization, a crucial endeavor as polarization poses a challenge to effective public health policy implementation and pandemic management. At the outset, the implications of our findings for pandemic communication (and health communication more generally) are discussed.

Effects of Reference Group Instructions on Big Five Trait Scores

People responding to personality questionnaires rate themselves by comparing themselves to some reference group, but this reference group is typically not specified. In this study, we examined the differences between Big Five trait scores when people responded to trait questionnaires without a specified reference group, as is typical in personality assessment, and when they were asked to compare themselves to people in general, close others, people their age, people their same gender, their ideal self, or their past self. We found that personality scores tended to be more adaptive for between-person comparisons than for within-person comparisons. We also found that unprompted instructions produced mildly higher scores across all traits. There were few differences among between-person reference group conditions. Men rated themselves as slightly more agreeable when comparing themselves to other men. Implications for basic and applied personality assessment are discussed.

Cultures in Water-Scarce Environments Are More Long-Term Oriented

Why do some cultures invest more for the long term, whereas others emphasize living in the moment? We took advantage of a natural experiment in Iran to test the theory that long-term water scarcity is an important cause of differences in long-term orientation and indulgence. We found that Iranians in a water-scarce province reported more long-term orientation and less indulgence than did Iranians in a nearby water-rich province (Study 1, N = 331). In a field study, Iranians in the water-scarce province sent more résumés for a long-term job ad we posted, whereas Iranians in the water-rich province sent more résumés for a short-term, flexible job (Study 2, N = 182). College students in Iran primed to think about increasing water scarcity in the environment endorsed long-term orientation more and indulgence less (Study 3, N = 211). Across 82 countries, long-run water scarcity predicted long-term orientation (Study 4). In sum, cultures in water-scarce environments value thinking for the long term more and indulgence less.

A Socioecological-Genetic Framework of Culture and Personality: Their Roots, Trends, and Interplay

Culture and personality are two central topics in psychology. Individuals are culturally influenced influencers of culture, yet the research linking culture and personality has been limited and fragmentary. We integrate the literatures on culture and personality with recent advances in socioecology and genetics to formulate the Socioecological-Genetic Framework of Culture and Personality. Our framework not only delineates the mutual constitution of culture and personality but also sheds light on (a) the roots of culture and personality, (b) how socioecological changes partly explain temporal trends in culture and personality, and (c) how genes and culture/socioecology interact to influence personality (i.e., nature × nurture interactions). By spotlighting the roles of socioecology and genetics, our integrative framework advances the understanding of culture and personality.

The social evolution of individual differences: Future directions for a comparative science of personality in social behavior

Personality is essential for understanding the evolution of cooperation and conflict in behavior. However, personality science remains disconnected from the field of social evolution, limiting our ability to explain how personality and plasticity shape phenotypic adaptation in social behavior. Researchers also lack an integrative framework for comparing personality in the contextualized and multifaceted behaviors central to social interactions among humans and other animals. Here we address these challenges by developing a social evolutionary approach to personality, synthesizing theory, methods, and organizing questions in the study of individuality and sociality in behavior. We critically review current measurement practices and introduce social reaction norm models for comparative research on the evolution of personality in social environments. These models demonstrate that social plasticity affects the heritable variance of personality, and that individual differences in social plasticity can further modify the rate and direction of adaptive social evolution. Future empirical studies of frequency- and density-dependent social selection on personality are crucial for further developing this framework and testing adaptive theory of social niche specialization.

Person-Culture Personality Fit: Dispositional Traits and Cultural Context Explain Country-Level Personality Profile Conformity

In general, people are influenced by the standards set forth by groups of others; however, the levels of such conformity vary between people and across cultures. Here, we investigated factors related to country-level personality profile conformity (i.e., person-culture personality fit) across ∼5.9 million participants, residing in 57 different countries. We examined how each of the Big Five personality traits and cultural tightness are associated with variation in person-culture personality fit. We found that scoring higher in Extraversion, Agreeableness, and Conscientiousness and residing in a tight cultural context explains increased personality profile conformity, while scoring higher in Openness and Neuroticism and residing in a loose cultural context explains lower personality profile conformity. Furthermore, we found that Openness and Extraversion interact with cultural context to predict levels of personality profile conformity. These findings reveal that both dispositional and cultural factors correspond to the tendency to conform to country-level norms.

Regional personality assessment through social media language

OBJECTIVE

We explore the personality of counties as assessed through linguistic patterns on social media. Such studies were previously limited by the cost and feasibility of large-scale surveys; however, language-based computational models applied to large social media datasets now allow for large-scale personality assessment.

METHOD

We applied a language-based assessment of the five factor model of personality to 6,064,267 U.S. Twitter users. We aggregated the Twitter-based personality scores to 2,041 counties and compared to political, economic, social, and health outcomes measured through surveys and by government agencies.

RESULTS

There was significant personality variation across counties. Openness to experience was higher on the coasts, conscientiousness was uniformly spread, extraversion was higher in southern states, agreeableness was higher in western states, and emotional stability was highest in the south. Across 13 outcomes, language-based personality estimates replicated patterns that have been observed in individual-level and geographic studies. This includes higher Republican vote share in less agreeable counties and increased life satisfaction in more conscientious counties.

CONCLUSIONS

Results suggest that regions vary in their personality and that these differences can be studied through computational linguistic analysis of social media. Furthermore, these methods may be used to explore other psychological constructs across geographies.

Mask Use Depends on the Individual, Situation, and Location-Even Without COVID-19 Transmission: An Observational Study in Shanghai

COVID-19 has drastically altered people’s mask-wearing behaviors around the world. What is unknown is how long these mask behaviors will last post-COVID-19? To investigate how individual, situational, and locational factors influence mask use in the absence of community spread of COVID-19, we conducted an observational study in public areas in the megacity of Shanghai, China. Researchers coded people’s mask use in various suburban and urban districts and outdoor and indoor locations with and without mask requirements. Firstly, even without any local transmissions in more than 40days, 62% of the sample (N=1,282) still wore masks in public places. The data showed that people in more urban areas wore masks more often and that people wore masks in places where it was mandated. Women also wore masks more than men, and older people complied more with mask enforcement policies. We found that more densely populated districts and areas with more inflow of non-locals also predicted more mask use. We argue that the pandemic has long-lasting effects on human behavior like mask usage and reflects individuals’ continual conformity to new social norms.

Bayes Factors show evidence against systematic relationships between the anchoring effect and the Big Five personality traits

Examining personality traits as predictors of human behaviour is of high interest. There are several but inconclusive reported relationships of personality and the susceptibility to the "anchoring effect", a tendency to adjust estimates towards a given anchor. To provide an answer to variably reported links between personality traits and the anchoring effect, we collected data from 1000 participants in the lab and validated typical anchoring effects and representative personality scores of the sample. Using Bayesian statistical data analyses, we found evidence for the absence of a relationship between anchoring effects and personality scores. We, therefore, conclude that there are no specific personality traits that relate to a higher susceptibility to the anchoring effect. The lack of a relationship between personality and the susceptibility to the anchoring effect might be due to the specific anchoring design, be limited to specific cognitive domains, or the susceptibility to anchors might reflect no reliable individual cognitive phenomena. In the next step, studies should examine the reliability of anchoring effects on the individual level, and testing relationships of individual traits and anchoring effects for other types of anchors, anchoring designs, or cognitive domains.

Geographic Variation in Personality is Associated With Fertility Across the United States

Levels of fertility and the shape of the age-specific fertility schedule vary substantially across U.S. regions with some states having peak fertility relatively early and others relatively late. Structural institutions or economic factors partly explain these heterogeneous patterns, but regional differences in personality might also contribute to regional differences in fertility. Here, we evaluated whether variation in extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience measured at the U.S. state-level was associated with the level, timing, and context of fertility across states above and beyond sociodemographics, voting behavior, and religiosity. Generally, states with higher levels of agreeableness and conscientiousness had more traditional fertility patterns, and states with higher levels of neuroticism and openness had more nontraditional fertility patterns, even after controlling for established correlates of fertility (r ~ |.50|). Personality is an overlooked correlate that can be leveraged to understand the existence and persistence of fertility differentials.

Comparability of Self–Reported Conscientiousness across 21 Countries

In cross–national studies, mean levels of self–reported phenomena are often not congruent with more objective criteria. One prominent explanation for such findings is that people make self–report judgements in relation to culture–specific standards (often called the reference group effect), thereby undermining the cross–cultural comparability of the judgements. We employed a simple method called anchoring vignettes in order to test whether people from 21 different countries have varying standards for Conscientiousness, a Big Five personality trait that has repeatedly shown unexpected nation–level relationships with external criteria. Participants rated their own Conscientiousness and that of 30 hypothetical persons portrayed in short vignettes. The latter type of ratings was expected to reveal individual differences in standards of Conscientiousness. The vignettes were rated relatively similarly in all countries, suggesting no substantial culture–related differences in standards for Conscientiousness. Controlling for the small differences in standards did not substantially change the rankings of countries on mean self–ratings or the predictive validities of these rankings for objective criteria. These findings are not consistent with mean self–rated Conscientiousness scores being influenced by culture–specific standards. The technique of anchoring vignettes can be used in various types of studies to assess the potentially confounding effects of reference levels. Copyright © 2011 John Wiley & Sons, Ltd.

The study of behaviour in personality psychology: Meaning, importance and measurement

The target paper was intended to initiate dialogue about challenges to personality psychology's progress as a truly behavioural science, and the commentaries' diverse reactions underscore the fact that these issues do indeed merit serious discussion. This response addresses several broad questions raised in the commentaries—what is behaviour, is behaviour of primary importance yet understudied, and what are the strengths and weaknesses of core types of behavioural data? In addition, it addresses an issue raised in several commentaries, but only briefly mentioned in the target paper—the fact that behaviour can be conceptualized and measured at multiple levels of abstraction. These issues have implications for the nature of personality psychology and for the research conducted by personality psychologists. Copyright © 2009 John Wiley & Sons, Ltd.

Self‐esteem and suicide rates in 55 Nations

Using recent data from the International Sexuality Description Project (ISDP), we examined whether national differences in self‐esteem across 55 nations are reflected in suicide rates. Results indicate that suicide is especially common in nations with relatively low levels of self‐esteem. This relation is consistent across sex lines, age of suicide and independent from several other relevant factors such as economic affluence, transition, individualism, subjective well‐being, and neuroticism. These findings provide support for the predictive validity of self‐esteem scores as assessed in the ISDP survey. They also contribute to a growing body of research documenting negative consequences associated with low self‐esteem. Possible implications for suicide prevention strategies are discussed.

Mechanisms of the national character stereotype: How people in six neighbouring countries of Russia describe themselves and the typical Russian

Altogether, 1448 individuals from six neighbouring countries of Russia in the Baltic Sea region (Finland, Estonia, Latvia, Lithuania, Poland and Belarus) described a ‘typical’ member of their own nation and a ‘typical’ Russian, as well as rated their own personality, using the National Character Survey (NCS). Results suggest that national character stereotypes are widely shared, temporally stable and moderately related to assessed personality traits, if all assessments are made using the same measurement instrument. In all studied countries, agreement between national auto‐stereotypes and assessed personality was positive and in half of the samples statistically significant. Although members of the six nations studied had a relatively similar view of the Russian national character, this view was not related with self‐rated personality traits of Russians but moderately with the Russian auto‐stereotype.

Personality profiles of cultures: Patterns of ethos

Culture and the human mind are deeply interdependent, because they co‐evolved. Personality traits were a preexisting feature of the primate mind and must have left an imprint on forms of culture. Trait taxonomies can structure ethnographies, by specifying institutions that reflect the operation of traits. Facets of ethos can be assessed by expert ratings or objective indicators. Ratings of ethos in Japan and the US were reliable and yielded plausible descriptions of culture. However, measures of ethos based on the analysis of stories were not meaningfully correlated with aggregate personality traits or national character stereotypes. Profiles of ethos may provide another axis that can be used with aggregate personality trait levels to predict behaviour and understand the operation of culture.

Sex, Education and Procrastination: An Epidemiological Study of Procrastinators’ Characteristics from A Global Sample

Procrastination is a common form of self–regulatory failure with substantive connections to lower levels of health, wealth and well–being. Conducting an epidemiological study, we determined the characteristics of prototypical procrastinators from a global sample based on several relevant self–reported demographic variables. Using an internet sampling strategy, we surveyed 16 413 English–speaking adults (58.3% women; 41.7% men: M age = 38.3 years, SD = 14), specifically on the variables of sex, age, marital status, family size, education, community location, and national origin. Almost all the results were statistically significant because of our large sample size. However, procrastination tendencies were most prominently associated with sex, age, marital status, education and nationality. Procrastinators tended to be young, single men with less education, residing in countries with lower levels of self–discipline. Notably, procrastination mediated the relationship between sex and education, providing further support that men are lagging behind women academically because of lower self–regulatory skills. Given procrastination's connection with a variety of societal ailments (e.g. excessive debt, delayed medical treatment), identifying risk factors and at risk populations should be helpful for directing preventative public policy.

Measurement Invariance of Three Narcissism Questionnaires Across the United States, the United Kingdom, and Germany

With a recent surge of research on narcissism, narcissism questionnaires are increasingly being translated and applied in various countries. The measurement invariance of an instrument across countries is a precondition for being able to compare scores across countries. We investigated the cross-cultural measurement invariance of three narcissism questionnaires (Brief Pathological Narcissism Inventory [B-PNI], Narcissistic Personality Inventory [NPI], and Narcissistic Admiration and Rivalry Questionnaire [NARQ]) and mean-level differences across samples from the United States (N = 2,464), the United Kingdom (N = 307), and Germany (N = 925). Overall, the B-PNI and NARQ functioned equivalently for the U.S. and U.K. participants. More violations of measurement invariance were found between Germany and the combined U.S. and U.K. samples, and for the NPI. In the B-PNI and NARQ, Americans scored higher than individuals from the United Kingdom regarding agentic aspects (self-sacrificing self-enhancement, admiration), while Germans scored lower than both Americans and U.K. individuals regarding antagonistic (entitlement rage, rivalry) and neurotic (hiding the self, contingent self-esteem) aspects. More inconsistent results were found for NPI facets. When noninvariance was present, observed means yielded biased results. Thus, the degree of measurement invariance across translated instrument versions should be considered in cross-cultural comparisons, even with culturally similar countries.

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.

Individual-Level Analyses of the Impact of Parasite Stress on Personality: Reduced Openness Only for Older Individuals

The parasite stress hypothesis predicts that individuals living in regions with higher infectious disease rates will show lower openness, agreeableness, and extraversion, but higher conscientiousness. This article, using data from more than 250,000 U.S. Facebook users, reports tests of these predictions at the level of both U.S. states and individuals and evaluates criticisms of previous findings. State-level results for agreeableness and conscientiousness are consistent with previously reported cross-national findings, but others (a significant positive correlation with extraversion and no correlation with openness) are not. However, effects of parasite stress on conscientiousness and agreeableness are not found when analyses account for the data's hierarchical structure and include controls. We find that only openness is robustly related to parasite stress in these analyses, and we also find a significant interaction with age: Older, but not younger, inhabitants of areas of high parasite stress show lower openness. Interpretations of the findings are discussed.

Examining reproducibility in psychology: A hybrid method for combining a statistically significant original study and a replication

The unrealistically high rate of positive results within psychology has increased the attention to replication research. However, researchers who conduct a replication and want to statistically combine the results of their replication with a statistically significant original study encounter problems when using traditional meta-analysis techniques. The original study's effect size is most probably overestimated because it is statistically significant, and this bias is not taken into consideration in traditional meta-analysis. We have developed a hybrid method that does take the statistical significance of an original study into account and enables (a) accurate effect size estimation, (b) estimation of a confidence interval, and (c) testing of the null hypothesis of no effect. We analytically approximate the performance of the hybrid method and describe its statistical properties. By applying the hybrid method to data from the Reproducibility Project: Psychology (Open Science Collaboration, 2015), we demonstrate that the conclusions based on the hybrid method are often in line with those of the replication, suggesting that many published psychological studies have smaller effect sizes than those reported in the original study, and that some effects may even be absent. We offer hands-on guidelines for how to statistically combine an original study and replication, and have developed a Web-based application ( https://rvanaert.shinyapps.io/hybrid ) for applying the hybrid method.

Emotion in enterprise social media systems

Purpose

The purpose of this paper is to investigate enterprise social media systems and quantified gender and status influences on emotional content presented in these systems.

Design/methodology/approach

Internal social media messages were collected from a global software company running an enterprise social media system. An indirect observatory test using Berlo’s “source–message–channel–receiver” model served as a framework to evaluate sender, message, channel and receiver for each text. These texts were categorized by gender and status using text analytics with SAP SA to produce sentiment indications.

Findings

Results reveal women use positive language 2.1 times more than men. Senior managers express positive language 1.7 times more than non-managers, and feeling rules affect all genders and statuses, but not necessarily as predicted by theory. Other findings show that public messages contained less emotional content, and women expressed more positivity to lower status colleagues. Men expressed more positivity to those in higher positions. Many gender and status stereotypes found in face-to-face studies are also present in digital enterprise social networks.

Research limitations/implications

Limitations include generalizability: all data were collected from a single enterprise social media system.

Practical implications

Managers establishing codes of conduct for social media use will find this research useful, particularly when promoting awareness of emotional expressiveness in online venues with subordinate colleagues.

Originality/value

This study offers a behavioral measurement approach free from validity issues found in self-reported surveys, direct observations and interviews. The collected data offered new perspectives on existing social theories within a new environment of computerized, enterprise social media.

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.

How Universal Is the General Factor of Personality? An Analysis of the Big Five in Forager Farmers of the Bolivian Amazon

In various personality models, such as the Big Five, a consistent higher order general factor of personality (GFP) can be identified. One view in the literature is that the GFP reflects general social effectiveness. Most GFP studies, however, have been conducted in Western, educated, industrialized, and rich democracies (WEIRD). Therefore, to address the question of the universality of the GFP, we test whether the GFP can also be identified in a preliterate indigenous sample of Tsimane by using self-reports, spouse reports, and interviewer ratings. In the Tsimane, a viable GFP could be identified and the intercorrelations between personality traits were significantly stronger than in samples from industrial countries. The GFP correlated with the ratings of social engagement. In addition, self and spouse ratings of the GFP overlapped. Overall, the findings are in line with the notion that the GFP is a human universal and a substantive personality factor reflecting social effectiveness.

Exploring Cultural Differences in the Extent to Which People Perceive and Desire Control

In a seminal theory piece, Weisz and colleagues argued that control over one's environment was less attainable and desirable in Japan than in America. Subsequently, many scholars have extrapolated from this argument to claim broad-based cultural differences in control: that Western/individualist cultures perceive and desire more personal control over their environment than do Eastern/collectivist cultures. Yet surprisingly little empirical research has put this claim to the test. To test this notion, in Study 1 we examined perceived control over one's life in 38 nationally representative samples ( N = 48,951). In Study 2, we measured desire for control in community samples across 27 nations ( N = 4,726). Together, the studies show lower levels of perceived and desired control in Japan than in any other nation. Over and above the Japan effect, there was no evidence for differences in perceived or desired control between individualist and collectivist nations, or between holistic and nonholistic nations.

Using Machine Learning to Advance Personality Assessment and Theory

Machine learning has led to important advances in society. One of the most exciting applications of machine learning in psychological science has been the development of assessment tools that can powerfully predict human behavior and personality traits. Thus far, machine learning approaches to personality assessment have focused on the associations between social media and other digital records with established personality measures. The goal of this article is to expand the potential of machine learning approaches to personality assessment by embedding it in a more comprehensive construct validation framework. We review recent applications of machine learning to personality assessment, place machine learning research in the broader context of fundamental principles of construct validation, and provide recommendations for how to use machine learning to advance our understanding of personality.

Revealed Traits: A Novel Method for Estimating Cross-Cultural Similarities and Differences in Personality

Cross-cultural research on personality has often led to surprising and countertheoretical findings, which have led to concerns over the validity of country-level estimates of personality (e.g., Heine, Buchtel, & Norenzayan, 2008). The present study explores how cross-cultural differences can be indexed via revealed trait estimates, which index the personality traits of individuals or groups indirectly through their likelihood of responding in particular ways to particular situations. In two studies, we measure self-reports of personality, revealed traits, and revealed preferences for different expected effects (e.g., experiencing excitement) of two cultural groups (U.S. and Singaporean participants). We found typical East–West differences in personality using self-report scales, such as lower levels of Conscientiousness- and Extraversion-related characteristics among Singaporean participants relative to U.S. participants. We found evidence of scale use extremity differences in self-report personality scales but not in revealed trait estimates. Using revealed traits, we found evidence of strikingly high levels of similarity in terms of overall action endorsement, revealed trait estimates, and revealed preferences. However, this was qualified by consistent differences in revealed trait estimates of Extraversion-related characteristics and less consistent differences in revealed trait estimates of Conscientiousness-related characteristics. We also found consistent differences in preferences for different expected effects; for example, Singaporean participants reported lower likelihood of performing actions expected to result in experiencing stimulation or excitement than U.S. participants. Results suggest that similarities in action endorsements and revealed traits may be driven by common preferences for social inclusion and benevolence, and differences may be driven by differing preferences for expending effort, experiencing stimulation, and social attention.

Moving chairs in Starbucks: Observational studies find rice-wheat cultural differences in daily life in China

Traditional paddy rice farmers had to share labor and coordinate irrigation in a way that most wheat farmers did not. We observed people in everyday life to test whether these agricultural legacies gave rice-farming southern China a more interdependent culture and wheat-farming northern China a more independent culture. In Study 1, we counted 8964 people sitting in cafes in six cities and found that people in northern China were more likely to be sitting alone. In Study 2, we moved chairs together in Starbucks across the country so that they were partially blocking the aisle (n = 678). People in northern China were more likely to move the chair out of the way, which is consistent with findings that people in individualistic cultures are more likely to try to control the environment. People in southern China were more likely to adjust the self to the environment by squeezing through the chairs. Even in China's most modern cities, rice-wheat differences live on in everyday life.

How Accurate Are National Stereotypes? A Test of Different Methodological Approaches

We compared different methodological approaches in research on the accuracy of national stereotypes that use aggregated mean scores of real people's personality traits as criteria for stereotype accuracy. Our sample comprised 16,713 participants from the Central Europe and 1,090 participants from the Baltic Sea region. Participants rated national stereotypes of their own country using the National Character Survey (NCS) and their personality traits using either the Revised NEO Personality Inventory or the NCS. We examined the effects of different (i) methods for rating of real people (Revised NEO Personality Inventory vs. NCS) and national stereotypes (NCS); (ii) norms for converting raw scores into T–scores (Russian vs. international norms); and (iii) correlation techniques (intraclass correlations vs. Pearson correlations vs. rank–order correlations) on the resulting agreement between the ratings of national stereotypes and real people. We showed that the accuracy of national stereotypes depended on the employed methodology. The accuracy was the highest when ratings of real people and national stereotypes were made using the same method and when rank order correlations were used to estimate the agreement between national stereotypes and personality profiles of real people. We propose a new statistical procedure for determining national stereotype accuracy that overcomes limitations of past studies. We provide methodological recommendations applicable to a wider range of cross national stereotype accuracy studies. Copyright © 2018 European Association of Personality Psychology

Underweight vs. overweight/obese: which weight category do we prefer? Dissociation of weight-related preferences at the explicit and implicit level

Objective

Although stigma towards obesity and anorexia is a well-recognized problem, no research has investigated and compared the explicit (i.e. conscious) and implicit (i.e. unconscious) preferences between these two conditions. The present study conducted this investigation in a sample of 4,806 volunteers recruited at the Project Implicit website (https://implicit.harvard.edu).

Methods

Explicit and implicit preferences were assessed among different weight categories (i.e. underweight, normal weight and overweight/obese) by means of self-reported items and the Multi-category Implicit Association Test, respectively.

Results

Preferences for the normal weight category were found both at the explicit and implicit levels when this category was compared with overweight/obese and underweight categories. On the contrary, when the underweight category was contrasted with the obese/overweight category, results differed at the explicit and implicit levels: pro-underweight preferences were observed at the explicit level, while pro-overweight/obese preferences were found at the implicit level.

Conclusions

These results indicate that preferences between overweight/obese and underweight categories differ at the explicit and implicit levels. This dissociation may have important implications on behaviour and decision-making.

The relations between conscientiousness and mental health in a North-European and a West-Asian culture

BACKGROUND

The relationship between conscientiousness, mental health and mental illness has been an issue for the last two decades.

AIMS

By using a dual model of mental health, the present study examined a non-linear relationship between conscientiousness and healthy or non-healthy symptoms in two different cultures.

METHOD

Participants in this study were 296 Iranian and 310 Swedish university students (18-24 years of age). We used two different conscientiousness scales; the 12-item conscientiousness subscale of the NEO/FFI as an imported (etic) scale, and a 10-item Iranian conscientiousness scale as an indigenous (emic) and culture-dependent scale.

RESULTS

In both conscientiousness scales, multivariate analysis of variance showed that conscientiousness differentiated among four mental health groups (languishing, troubled, symptomatic and flourishing), although languishing and troubled individuals were less conscientious than flourishing and symptomatic individuals. Furthermore, the non-healthy symptomatic individuals were more conscientiousness than flourishing individuals. The results showed no significant differences between the two cultures in terms of the four mental health categories.

CONCLUSIONS

It was concluded that the relationship between conscientiousness and mental health/mental illness is more a non-linear relationship than a linear one.

Rethinking “Generation Me”: A Study of Cohort Effects from 1976-2006

Social commentators have argued that changes over the last decades have coalesced to create a relatively unique generation of young people. However, using large samples of U.S. high-school seniors from 1976 to 2006 (Total N = 477,380), we found little evidence of meaningful change in egotism, self-enhancement, individualism, self-esteem, locus of control, hopelessness, happiness, life satisfaction, loneliness, antisocial behavior, time spent working or watching television, political activity, the importance of religion, and the importance of social status over the last 30 years. Today's youth are less fearful of social problems than previous generations and they are also more cynical and less trusting. In addition, today's youth have higher educational expectations than previous generations. However, an inspection of effect sizes provided little evidence for strong or widespread cohort-linked changes.

Comparisons of Daily Behavior Across 21 Countries

While a large body of research has investigated cultural differences in behavior, this typical study assesses a single behavioral outcome, in a single context, compared across two countries. The current study compared a broad array of behaviors across 21 countries ( N = 5,522). Participants described their behavior at 7:00 p.m. the previous evening using the 68 items of the Riverside Behavioral Q-sort (RBQ). Correlations between average patterns of behavior in each country ranged from r = .69 to r = .97 and, in general, described a positive and relaxed activity. The most similar patterns were United States/Canada and least similar were Japan/United Arab Emirates (UAE). Similarities in behavior within countries were largest in Spain and smallest in the UAE. Further analyses correlated average RBQ item placements in each country with, among others, country-level value dimensions, personality traits, self-esteem levels, economic output, and population. Extroversion, openness, neuroticism, conscientiousness, self-esteem, happiness, and tolerant attitudes yielded more significant correlations than expected by chance.

Specificity, contexts, and reference groups matter when assessing autistic traits

Many of the personality and behavioral traits (e.g., social imperviousness, directness in conversation, lack of imagination, affinity for solitude, difficulty displaying emotions) that are known to be sensitive to context (with whom?) and reference group (according to whom?) also appear in questionnaire-based assessments of autistic traits. Therefore, two experiments investigated the effects of specifying contexts and reference groups when assessing autistic traits in autistic and non-autistic participants. Experiment 1 (124 autistic and 124 non-autistic participants) demonstrated that context matters when assessing autistic traits (F(1,244) = 267.5, p < .001, η²_p = .523). When the context of the Broad Autism Phenotype Questionnaire was specified as the participants’ out-group (e.g., “I like being around non-autistic people” or “I like being around autistic people”), both autistic and non-autistic participants self-reported having more autistic traits; when the context was specified as the participants’ in-group, participants reported having fewer autistic traits. Experiment 2 (82 autistic and 82 non-autistic participants) demonstrated that reference group matters when assessing autistic traits (F(2,160) = 94.38, p < .001, η²_p = .541). When the reference group on the Social Responsiveness Scale was specified as the participants’ out-group (e.g., “According to non-autistic people, I have unusual eye contact”), autistic participants reported having more autistic traits; when the reference group was their in-group, autistic participants reported having fewer autistic traits. Non-autistic participants appeared insensitive to reference group on the Social Responsiveness Scale. Exploratory analyses suggested that when neither the context nor the reference group is specified (for assessing autistic traits on the Autism-Spectrum Quotient), both autistic and non-autistic participants use the majority (“non-autistic people”) as the implied context and reference group.

Mean Profiles of the NEO Personality Inventory

The Revised NEO Personality Inventory (NEO-PI-R) and its latest version, the NEO-PI-3, were designed to measure 30 distinctive personality traits, which are grouped into Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness domains. The mean self-rated NEO-PI-R scores for 30 subscales have been reported for 36 countries or cultures in 2002. As a follow-up, this study reports the mean scores of the NEO-PI-R/3 for 71,870 participants from 76 samples and 62 different countries or cultures and 37 different languages. Mean differences in personality traits across countries and cultures were about 8.5 times smaller than differences between any two individuals randomly selected from these samples. Nevertheless, a multidimensional scaling of similarities and differences in the mean profile shape showed a clear clustering into distinctive groups of countries or cultures. This study provides further evidence that country/culture mean scores in personality are replicable and can provide reliable information about personality dispositions.

Exposure to Celebrities as a Possible Explanatory Mechanism in the Perception of American Narcissism

Recent studies have examined perceived levels of narcissism as rated by Americans and non-Americans and found support for early assumptions that American culture is perceived as narcissistic (Miller et al., 2015; Wolfe, 1976). However, specific reasons for this phenomenon remain unclear. The aim of the current study was to test if proximal, salient exposure to narcissistic exemplars (i.e., celebrities) acts as one mechanism that explains this perception. Participants (N = 300) were randomly assigned to exposure to either celebrity magazines or neutral magazines conditions, and subsequently asked to provide American PNC ratings. No hypothesized differences by condition were found in terms of narcissism or FFM profile; however, American PNCs were rated as pathologically narcissistic in both conditions.

Birds of a Feather Do Flock Together

Friends and spouses tend to be similar in a broad range of characteristics, such as age, educational level, race, religion, attitudes, and general intelligence. Surprisingly, little evidence has been found for similarity in personality-one of the most fundamental psychological constructs. We argue that the lack of evidence for personality similarity stems from the tendency of individuals to make personality judgments relative to a salient comparison group, rather than in absolute terms (i.e., the reference-group effect), when responding to the self-report and peer-report questionnaires commonly used in personality research. We employed two behavior-based personality measures to circumvent the reference-group effect. The results based on large samples provide evidence for personality similarity between romantic partners ( n = 1,101; rs = .20-.47) and between friends ( n = 46,483; rs = .12-.31). We discuss the practical and methodological implications of the findings.

Cultural perspective in open-ended interviews – The importance of being adaptable

When conducting open-ended qualitative interviews, it is important to remember that the method originates from the Western perspective. In China we encountered a number of problems when using this method, with little information on dealing with them in the literature, or if information does exist it has not attracted enough attention in the research community to be readily accessible. We therefore saw a need to uncover these difficulties, encouraging a broader discussion about these types of cross-cultural issues and how to handle them in research situations. The differences between the Chinese interview situation and the European interview situation will be presented in seven points. We will present examples and discuss potential sources for these problems and their implications for ecological validity.

Examining Variability in Values Attributed to Culture

Prior work examining the role of cultural groupings (i.e., national membership) on personal values showed small to moderate amounts of variability attributable to culture, refuting the idea that culture determines values. We extend this research by examining the proportion of variance in values that could be explained by cultural membership. Because there is no definitive level of proportion of variance that would lead to a conclusion that values are culturally determined, personality, which is arguably not culturally determined, was used as a relative benchmark. Language groups were used as an alternate conception of cultural groupings. A large data set of 144,857 workers from across 31 major language groups revealed that language groups explained a significant and non-negligible amount of variance in personal value dimensions (7%-17%). Nevertheless, this was not significantly larger than any single personality dimension (3%-12%). In other words, our data failed to support the notion that personal values are strongly determined by cultural groupings compared with personality.

Stereotype (In)Accuracy in Perceptions of Groups and Individuals

Are stereotypes accurate or inaccurate? We summarize evidence that stereotype accuracy is one of the largest and most replicable findings in social psychology. We address controversies in this literature, including the long-standing and continuing but unjustified emphasis on stereotype inaccuracy, how to define and assess stereotype accuracy, and whether stereotypic (vs. individuating) information can be used rationally in person perception. We conclude with suggestions for building theory and for future directions of stereotype (in)accuracy research.

What can cross-cultural correlations teach us about human nature?

Many recent evolutionary psychology and human behavioral ecology studies have tested hypotheses by examining correlations between variables measured at a group level (e.g., state, country, continent). In such analyses, variables collected for each aggregation are often taken to be representative of the individuals present within them, and relationships between such variables are presumed to reflect individual-level processes. There are multiple reasons to exercise caution when doing so, including: (1) the ecological fallacy, whereby relationships observed at the aggregate level do not accurately represent individual-level processes; (2) non-independence of data points, which violates assumptions of the inferential techniques used in null hypothesis testing; and (3) cross-cultural non-equivalence of measurement (differences in construct validity between groups). We provide examples of how each of these gives rise to problems in the context of testing evolutionary hypotheses about human behavior, and we offer some suggestions for future research.
