Essentialist beliefs about personality and their implications

Two studies examine implicit theories about the nature of personality characteristics, asking whether they are understood as underlying essences. Consistent with the hypothesis, essentialist beliefs about personality formed a coherent and replicable set. Personality characteristics differed systematically in the extent to which they were judged to be discrete, biologically based, immutable, informative, consistent across situations, and deeply inherent within the person. In Study 1, the extent to which characteristics were essentialized was positively associated with their perceived desirability, prevalence, and emotionality. In Study 2, essentialized characteristics were judged to be particularly important for defining people's identity, for forming impressions of people, and for communicating about a third person. The findings indicate that people understand some personality attributes in an essentialist fashion, that these attributes are taken to be valued elements of a shared human nature, and that they are particularly central to social identity and judgment.     

Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.

Immigration from the perspective of hosts and immigrants: Roles of psychological essentialism and social identity

Implicit person theory research can be conceptualized within the framework of psychological essentialism. Essentialist beliefs are associated with entity theories and both predict phenomena such as stereotyping. The present research extended previous work on the links between implicit theories and social identity processes, examining how essentialist beliefs are associated with social identification and processes related to prejudice and intergroup perception. After developing a new measure of essentialist beliefs in Study 1, Study 2 showed that these beliefs were associated with negative bias towards immigrants, particularly when participants were primed with an exclusive social identity. In Study 3, essentialist beliefs among immigrants moderated their adoption of Australian identity as a self-guide during acculturation. Essentialist beliefs therefore play a significant role in the psychology of social identity.     

Why didn’t you say something? Effects of after-event reviews on voice behaviour and hierarchy beliefs in multi-professional action teams

Team decision-making can go wrong when individuals fear to voice suggestions or concerns to higher status team members. We investigate how after-event reviews (AERs) can be used to promote voice behaviour and hierarchy-attenuating beliefs in multi-professional action teams. We hypothesized that (1) lower status team members will speak up more following an assertiveness-specific AER (ASAER) as compared to a teamwork-generic AER (TGAER) and (2) that an ASAER leads to stronger endorsement of hierarchy-attenuating beliefs than the TGAER. To test these hypotheses, we implemented simulations of medical emergencies with 20 healthcare teams consisting of low (i.e., nurses) and high-status (i.e., physicians) professions. After participating in one of the two AERs, teams managed a simulation in which a higher status confederate engaged in potentially harmful actions. Behavioural coding of the videotaped simulations and assessment of team members’ hierarchy beliefs supported both hypotheses: nurses spoke up more following the ASAER than following the TGAER and both professional groups reported significantly higher levels of hierarchy-attenuating beliefs following the ASAER as compared to the TGAER. We discuss how AERs can affect upward voice and increase awareness for the potential downsides of status hierarchies in multi-professional teams.     

Automated classification of demographics from face images: A tutorial and validation

Examining disparities in social outcomes as a function of gender, age, or race has a long tradition in psychology and other social sciences. With an increasing availability of large naturalistic data sets, researchers are afforded the opportunity to study the effects of demographic characteristics with real‐world data and high statistical power. However, since traditional studies rely on human raters to asses demographic characteristics, limits in participant pools can hinder researchers from analyzing large data sets. Automated procedures offer a new solution to the classification of face images. Here, we present a tutorial on how to use two face classification algorithms, Face++ and Kairos. We also test and compare their accuracy under varying conditions and provide practical recommendations for their use. Drawing on two face databases (n = 2,805 images), we find that classification accuracy is (a) relatively high, with Kairos generally outperforming Face++ (b) similar for standardized and more variable images, and (c) dependent on target demographics. For example, accuracy was lower for Hispanic and Asian (vs. Black and White) targets. In sum, we propose that automated face classification can be a useful tool for researchers interested in studying the effects of demographic characteristics in large naturalistic data sets.     

Predictors of perceived susceptibility of breast cancer and changes over time: a mixed modeling approach

OBJECTIVE: To examine predictors of perceived susceptibility to breast cancer and assess differences across three dependent measures. DESIGN: Annual surveys were completed by US women veterans (N = 3,758) participating in a repeat mammography intervention trial. Multivariable non-linear mixed model analyses examined individual- and group-level changes in perceived susceptibility to breast cancer. DEPENDENT MEASURES: Three single-item measures of perceived susceptibility to breast cancer (percent risk, ordinal risk, and comparative risk likelihood). Predictors included demographic, health status, health behavior, affect, knowledge, and subjective norm variables. RESULTS: Breast symptoms and greater cancer worry increased perceived susceptibility for all three measures. Other predictors varied by dependent measure. Random change, indicating individual variability, was observed for percent risk only. CONCLUSION: Despite small model effect sizes, breast symptoms and cancer worry were consistent predictors and may be good targets for messages designed to influence women's perceived susceptibility to breast cancer. Researchers may benefit from using measures of perceived susceptibility with larger response scales, but additional measurement research is needed. Combining indicators of perceived susceptibility may be undesirable when different predictors are associated with different measures.     

Trust and Trustworthiness of Christians,Muslims, and Atheists/Agnostics in the United States

Trust, a cornerstone of economic development, is promoted within religions. In a randomized controlled trial, we examine how trust and trustworthiness vary across religions (Christianity and Islam), religiosity, and atheists/agnostics in the United States. Three novel findings emerge. First, Christians are trusted more than Muslims and nonbelievers, which is due to a Christian ingroup bias––Christians trust Christians more than they trust Muslims and nonbelievers, while Muslims and nonbelievers trust all groups the same. Second, religiosity matters to trust. Religious people trust those of higher religiosity more, but only if they are of the same religion. In contrast, nonbelievers trust people of higher religiosity less. Third, trustworthiness among nonbelievers is somewhat lower than that of the religious, especially toward Christians. We speculate that the lower reciprocity originates in the prejudice toward nonbelievers. Our results may help explain discrimination against Muslims and nonbelievers, given that discrimination often originates in distrust.     

Heightened male aggression toward sexualized women following romantic rejection: The mediating role of sex goal activation

Research from a variety of disciplines suggests a positive relationship between Western cultural sexualization and women's likelihood of suffering harm. In the current experiment, 157 young men were romantically rejected by a sexualized or non‐sexualized woman then given the opportunity to blast the woman with loud bursts of white noise. We tested whether the activation of sexual goals in men would mediate the relationship between sexualization and aggressive behavior after romantic rejection. We also tested whether behaving aggressively toward a woman after romantic rejection would increase men's feelings of sexual dominance. Results showed that interacting with a sexualized woman increased men's sex goals. Heightened sex goal activation, in turn, predicted increased aggression after romantic rejection. This result remained significant despite controlling for the effects of trait aggressiveness and negative affect. The findings suggest that heightened sex goal activation may lead men to perpetrate aggression against sexualized women who reject them.
