Perceptions of Income Inequality and Women's Intrasexual Competition

Income inequality has been empirically linked to interpersonal competition and risk-taking behaviors, but a separate line of findings consistently shows that individuals have inaccurate perceptions of the actual levels of income inequality in society. How can inequality be both consistently misperceived and yet a reliable predictor of behavior? The present study extends both these lines of research by evaluating if the scope of input used to assess income inequality (i.e., at the national, state, county, or postal code level) can account for perception discrepancies and if actual/perceived inequality is associated with female intrasexual competition. Female participants recruited online from the general US population (n = 691) provided demographic information, measures of perceived income inequality, and measures of intrasexual competition attitudes and behavior. Actual and perceived income inequality (at any level) did not predict negative attitudes toward other women or female weighting of physical appearance as a desirable trait. Perceived income inequality and actual county-level inequality was, however, predictive of female competition in the form of self-sexualization clothing choice. Further analyses found that age and importance placed on physical attractiveness also predicted women's clothing choices. Perceptions of income inequality were predicted not by actual Gini indices, but by beliefs about the levels of poverty and income gaps. These results highlight the importance of better understanding the proximate cues by which people perceive environmental features such as inequality, and how those cues are used to adjust interpersonal behaviors.

A Slim Majority: The Influence of Sex Ratio on Women's Body Dissatisfaction and Weight Loss Motivations

The current investigation examined whether women's perceptions of the sex ratio (ratio of women to men) in the local population influence their body dissatisfaction and weight loss motivations. A higher ratio of women to men in a given population signifies a relative abundance of same-sex mating competitors, intensifying female intrasexual competition. Five studies (N = 1,776) tested the hypotheses that women's perceptions of a female-skewed sex ratio would correspond to increased feelings of intrasexual competitiveness and perceptions of unfavorable mating prospects, which would, in turn, be associated with heightened body dissatisfaction and weight loss motivations. Among university and community women (Studies 1and 2), perceptions of a female-skewed sex ratio corresponded to greater intrasexual competitiveness, increased body dissatisfaction, and increased dieting inclinations. Among single women, assessments of a female-skewed sex ratio corresponded to perceptions of unfavorable mating prospects, increased romantic pressure to alter their appearance, and higher body dissatisfaction (Study 3). Studies 4 and 5 experimentally manipulated perceived sex ratio. Women in the female-skewed condition felt less satisfied with their weights and shapes, but only if they believed the manipulation (Study 4). In Study 5, using a within-subjects design, women who evaluated a male-skewed (vs. female-skewed) dating profile array subsequently desired to lose less weight. Findings suggest women's perceptions of their social environments may contribute to body image and dieting motivations.

Girls Tolerate Girls, men condemn men: Gender differences in the impact of beautification strategies on trustworthiness and morality evaluation

It's not just women who aspire to enhance their appearance; it's a universal human desire. An increasing number of men are gradually embracing beautification strategies as well. The impact of gender on perceptions of strategies users remains uncertain. This study focuses on the role of gender in beautification strategies and their influence on trustworthiness and morality evaluations. It aims to analyze the role played by both the gender of evaluators and the gender of targets, while also comparing the differences between the two most popular beautification strategies, makeup and cosmetic surgery, in shaping trustworthiness and morality evaluations. The results revealed male participants demonstrated a stronger negative bias towards these users, particularly male users. On the other hand, the research revealed that females exhibited greater tolerance when evaluating same-sex makeup users. Conversely, males gave more negative evaluations to same-sex strategies users. Furthermore, the results showed morality and trustworthiness evaluation for beautification targets was predicted by evaluators' acceptance of cosmetic surgery. This study not only contributes to the existing literature on gender differences in beautification strategies but also offers a gender-based perspective to help reduce the stigma associated with these strategies.

Beyond the surface: accounting for confounders in understanding the link between collectivism and COVID-19 pandemic in the United States

According to the parasite-stress theory, collectivism serves as a trait of ingroup assortative sociality, providing defense against infectious diseases. This study investigated the association between cultural collectivism and COVID-19 severity at the state (Study 1: N = 51), county (Study 2: N = 3,133), and daily (Study 3: N = 52,806) levels from the beginning of 2020 to the end of 2022. State-level collectivism was assessed using two distinct measures: the U.S. collectivism index, focusing on social interconnectedness and interdependence, and the subjective-culture individualism-collectivism index (reversed), capturing attitudes and beliefs related to religion, abortion, and same-sex marriage. By employing random-intercept multilevel models, the results demonstrated significant and negative effects of state-level collectivism, as measured by the U.S collectivism index, on COVID-19 cases per million, COVID-19 deaths per million, and composite COVID-19 severity index, after controlling for confounding factors, such as socioeconomic development, ecological threats, disease protective behaviors, cultural norms, and political influences. A mini meta-analysis (Study 4: N = 9) confirmed the significance of these effects across studies. These findings supported the proactive role of collectivism in defending against the novel coronavirus in the United States, aligning with the parasite-stress theory of sociality. However, the subjective-culture individualism-collectivism index (reversed) did not exhibit a significant relationship with COVID-19 severity when confounding factors were considered. The high correlation between the subjective-culture individualism-collectivism index (reversed) and the controlled variables suggested shared variance that could diminish its impact on COVID-19 outcomes. Accordingly, the present findings underscore the significance of accounting for confounding factors when examining the association between collectivism and COVID-19 severity at population level. By considering relevant confounding factors, researchers could gain a comprehensive understanding of the complex interplay between cultural collectivism and its influence on COVID-19 severity. Overall, this research contributes to our understanding of how cultural collectivism shapes the COVID-19 pandemic in the United States, emphasizing the importance of adjusting for confounding effects in population level studies.

We Need Tough Brothers and Sisters in a Tight World: Cultural Tightness Leads to a Preference for Dominant and Muscular Leaders

Cultural tightness is characterized by strong norms and harsh punishments for deviant behaviors. We hypothesized that followers in tight (vs. loose) cultures would more strongly prefer muscular leaders. This hypothesis was confirmed across seven studies (N = 1,615) employing samples from the United States, the United Kingdom, and China. Using actual political leaders, we demonstrated that the tighter the state's culture was, the more muscular the elected governor was (Study 1). Temporarily situating participants in a tight (vs. loose) culture made them select a leader higher on muscularity but not on body fat, and the effects obtained occurred for both male and female leaders (Studies 2-3B). In addition, we demonstrated the mediating role of authoritarianism and a preference for a dominant leadership in this process (Studies 4-5B). These results demonstrate the importance of considering the interface between culture and the physical appearance of leaders.

Personal Relative Deprivation Increases Men's (but Not Women's) Hostile Sexism: The Mediating Role of Sense of Control

Hostile sexism is a blatant and explicit form of sexism consisting of antagonistic attitudes toward women. We hypothesized that men's personal relative deprivation, a subjectively perceived disadvantage, would predict their hostile sexism toward women. In addition, we expected that, if this effect occurs, a sense of control would act as a mediator. Five studies ( N = 1352) confirmed these hypotheses. Study 1 showed that personal relative deprivation predicted hostile sexism only for men, but not for women among Chinese college students. In addition, we observed the effect of personal relative deprivation only on hostile sexism, but not on benevolent sexism. Study 2, which employed participants from the United States, directly replicated the findings of Study 1. Studies 3 and 4 further showed that a sense of control acted as a mediator in this process. As such, increased hostile sexism attitude (Study 3) and hostile sexism behavior (Study 4) predicted by personal relative deprivation could result from a reduced sense of control. Study 5 further provided causal evidence that a temporarily induced state of personal relative deprivation resulted in a higher level of hostile sexism via a reduced sense of control. We discuss theoretical and practical implications for relative deprivation, gender inequality, and interventions.

Threatened humanity in a tight world: Cultural tightness results in self-objectification

Self-objectification can be considered as a specific kind of self-dehumanization that consists of a perception of oneself as more instrument-like than human-like and a decreased self-attribution of mental states. Self-objectification is commonly observed, and its contributing factors need to be better understood. In the present research, we examined whether cultural tightness, which entails strong social norms and punishments for deviant behaviors, is an antecedent to self-objectification. Our hypotheses were confirmed by four studies, involving quasi-experiments and fully controlled experiments ( N = 2,693). In particular, Chinese college students living in a region with a tight culture (compared to a loose culture, Study 1), American employees working in an industry with a tight corporate culture (compared to a loose culture, Study 2), American participants who were induced to support cultural tightness (vs. cultural looseness, Study 3), and those who were situated in a simulated tight culture (vs. a loose culture, Study 4) all showed increased levels of self-objectification. As such, they acknowledged their personhood less and focused more on their instrumentality. Implications are discussed.

Women's Self-Objectification Under Competition When They Believe Sex Is Power

Competitions are ubiquitous and their psychological consequences for women have not received sufficient attention. For this research, we tested whether competition, in either work settings or a broader form of competition for resources, would interact with the sex is power belief to result in self-objectification among women. This prediction was confirmed by a series of studies (N = 1416), including correlational studies, a quasi-experiment, and fully controlled experiments, with samples including company employees, MBA students with work experience, college students currently competing in a job market, and Mechanical Turkers. Competition (or a sense of competition) as a feature of the working environment (Study 1), a real state in life (Study 2), or a temporarily activated state (Studies 3-5) resulted in self-objectification among women who believe sex is power (Study 1) or who enter such a mindset (Studies 2-5). This effect further impaired the pursuit of personal growth (Studies 4 and 5).

Hormonal contraceptives as disruptors of competitive behavior: Theoretical framing and review

Emerging evidence suggests that hormonal contraceptives (HCs) impact psychological outcomes through alterations in neurophysiology. In this review, we first introduce a theoretical framework for HCs as disruptors of steroid hormone modulation of socially competitive attitudes and behaviors. Then, we comprehensively examine prior research comparing HC users and non-users in outcomes related to competition for reproductive, social, and financial resources. Synthesis of 46 studies (n = 16,290) led to several key conclusions: HC users do not show the same menstrual cycle-related fluctuations in self-perceived attractiveness and some intrasexual competition seen in naturally-cycling women and, further, may show relatively reduced status- or achievement-oriented competitive motivation. However, there a lack of consistent or compelling evidence that HC users and non-users differ in competitive behavior or attitudes for mates or financial resources. These conclusions are tentative given the notable methodological limitations of the studies reviewed. Implications and recommendations for future research are discussed.

An exchange orientation results in an instrumental approach in intimate relationships

Although the possession of instrumentality (i.e., partner B being useful to partner A's goal pursuit) can facilitate relationship satisfaction, taking an instrumental approach (i.e., A focusing on B's usefulness and seeing B as a tool to facilitate personal goal attainment) is (often) considered as a callous and depersonalized approach to forming relationships. The current research examined whether adopting an exchange orientation amplifies the tendency for people to take an instrumental approach via the motive to maximize self-gain. Four studies (N = 1446) utilizing samples across different countries, including the United Kingdom, the United States and China, supported this hypothesis. Specifically, during relationship initiation, an exchange (vs. non-exchange) orientation made participants place higher importance on instrumentality rather than traits facilitating intimacy and bonding (Study 1). For established relationships, participants who chronically adopted an exchange orientation (Study 2) and who were temporarily induced to do so (vs. control; Study 3) were more likely to view their significant other as a tool. The final quasi-experiment (Study 4) showed that requiring or being required to offer a bride price - an embodiment of exchange orientation - predicted instrumentality in marriage and subsequently impaired relationship satisfaction. Implications are discussed.

Sexual Receptivity Signal of Lordosis Posture and Intra-Sexual Competition in Women

Previous research has shown that women may use self-enhancement strategies to compete with one other. Lumbar curvature in women is considered to enhance a woman′s attractiveness, potentially due to its role in bipedal fetal load and sexual receptiveness. The current study investigated the role of lumbar curvature on women’s perceptions of sexual receptiveness as well as its role in women’s intrasexual competitiveness. Study 1 (N = 138) tested and confirmed that women’s intrasexual competition influences their perception of sexual receptivity of women as a function of lordosis posture depicted in a standing posture. Study 2 (N = 69) replicated these results and extended them to other postures, namely, the quadruped and supine positions. Study 3 (N = 106), using a two-alternative forced-choice task, revealed that other women perceive relatively larger arched-back postures as more threatening to their relationship and frequently as being more attractive. Collectively, this work suggests that women consider a lordotic posture in other women as a signal of sexual receptivity and perceive it as a threat to their relationship. This research provides robust support for the sexually receptivity hypothesis of lumbar curvature, questioning the alternative morphological vertebral wedging hypothesis.

The role of ingroup assortative sociality in the COVID-19 pandemic: A multilevel analysis of google trends data in the United States

This study tested how family ties and religiosity, two extended elements of ingroup assortative sociality, would predict group-level COVID-19 severity in the U.S. and how COVID-19 threat would predict ingroup assortative sociality at a weekly level. Multilevel models which analyzed the state-level archival (e.g., religious participation) and Google trends data (e.g., marriage for family ties; prayer for religiosity) on ingroup assortative sociality showed that religious search volume (from 2004 to 2019) significantly and negatively predicted COVID-19 severity (i.e., shorter time delay of first documented cases, shorter overall doubling times, higher reproductive ratio and higher case fatality ratio) across states (Study 1a) and counties (Study 1b) while search volume for family ties only significantly and negatively predicted county-level COVID-19 severity. Multilevel analyses also found that weekly COVID-19 severity weakly predicted weekly search volume of marriage and religion (Study 2a), but when COVID-19 threat was in the collective consciousness in a given week (i.e., Google search volume for coronavirus within 52 weeks), collective levels of ingroup assortative sociality increased from the previous week (Study 2b). Evidence across studies suggested that religiosity, compared with family ties, could serve a more important role for the U.S. people during the deadly pandemic.

Group-level human values estimated with web search data and archival data explain the geographic variation in COVID-19 severity in the United States

OBJECTIVES

Personal Focus values (PF = Openness to change values + Self-enhancement values) motivate self-centred behaviours, and Social Focus values (SF = Conservation values + Self-transcendence values) promote self-sacrificial counterparts. This research investigated how a state-level PF-SF value-continuum would explain the geographic variation in COVID-19 severity in the United States.

DESIGN

This research estimated state-level values by Google search data (from 2004 to 2019) on value-related words (e.g. family for conservation values) (Study 1a) and archival indicators (e.g. gun ownership rate for security values) (Study 1b). COVID-19 severity was measured by shorter time delay of first documented cases, shorter overall doubling times, higher reproductive ratio and higher case fatality ratio. Hierarchical and multilevel analyses examined how state-level values would predict COVID-19 severity across U.S. states (Studies 1a and 1b) and 3,135 counties (Study 2).

RESULTS

State-level analyses accounting for spatial autocorrelation and covariates (e.g. COVID-19 testing rate, airport traffic, personality, etc.) revealed that the PF-SF value-continuums measured with different methods positively and significantly predicted COVID-19 severity, and the effects of state-level values on county-level COVID-19 severity were significant when county- and state-level covariates were controlled.

CONCLUSION

Social focus values may mitigate the devastating effect of COVID-19 in the United States.
