Motivations to Enhance One's Facial Hair: Affiliation, Rivalry, and Stress.

Facial hair is a sexually dimorphic trait with potential evolutionary and sociocultural functions. Bearded men are perceived as dominant, aggressive, and masculine, but also as having better parenting skills. Men may intentionally manage the amount and shape of their facial hair as a part of their self-promotion strategy; however, facial hair management entails costs in terms of time, effort, and money. We explored psychological factors associated with facial hair enhancement motivation among men. A total of 414 men (aged 18-40 years) reported the current amount of their facial hair along with their facial hair enhancement motivations, gender role stress, intrasexual competitiveness, and fundamental social motives. Willingness to care for facial hair was associated with the amount of facial hair men claimed to have and correlated with the fundamental social motives of affiliation and social status, intrasexual competition, and gender role stress. Therefore, facial hair enhancement may be regarded as a self-presentation strategy aimed at acquiring a beneficial position in social networks.

Ego-Boosting Hormone: Self-Reported and Blood-Based Testosterone Are Associated With Higher Narcissism.

Grandiose narcissism is defined as increased motivation for status and viewing oneself as entitled and superior to others. We hypothesized that these tendencies might be associated with basal levels of testosterone because testosterone is considered the most social hormone-driving dominance and the motivation to achieve social status. We distinguished between two facets of grandiose narcissism: agentic (i.e., the tendency to self-promotion in order to win others' admiration and social influence) and antagonistic (i.e., a reactive strategy used to restore threatened status). In 283 adult men, we examined the association between these facets of narcissism and blood-tested and self-reported testosterone levels. Agentic narcissism-the default narcissistic strategy-was positively associated with both testosterone indicators. Moreover, self-reported and objectively measured testosterone were positively correlated. These findings extend previous work by showing that the facets of narcissism have distinct hormonal underpinnings.

Men's Facial Hair Preferences Reflect Facial Hair Impression Management Functions Across Contexts and Men Know It.

Men with distinct facial hair are perceived as more aggressive, dominant, older, and more formidable, mostly by other men. However, despite considerable interest in the social perception of beardedness, only a few studies have explored men's preferences toward facial hair. We investigated men's preferences toward facial hair and whether their judgments of facial hair appropriateness in social situations depended on their actual beardedness and the type of social interaction (N = 509; age: M = 29.35, SD = 7.24). Men preferred having more facial hair, particularly when they have a heavy stubble or a full beard. Men preferred more facial hair for themselves compared to other men, suggesting that men's preferences for facial hair could be based on the frequency-dependent value of a display, namely more value assigned to rarer attributes. Men's judgments of the appropriateness of facial hair were sensitive to social situations for displaying facial hair as well. More facial hair was considered more appropriate for informal situations, especially with another man. Social norms associated with formal interaction could, therefore, limit the impression management functions of beards in intrasexual competition.

Individual Differences in How Desirable People Think They Are as a Mate.

Mate value is an important concept in mate choice research although its operationalization and understanding are limited. Here, we reviewed and evaluated previously established conceptual and methodological approaches measuring mate value and presented original research using individual differences in how people view themselves as a face-valid proxy for mate value in long- and short-term contexts. In data from 41 nations (N = 3895, Mage = 24.71, 63% women, 47% single), we tested sex, age, and relationship status effects on self-perceived mate desirability, along with individual differences in the Dark Triad traits, life history strategies, peer-based comparison of desirability, and self-reported mating success. Both sexes indicated more short-term than long-term mate desirability; however, men reported more long-term mate desirability than women, whereas women reported more short-term mate desirability than men. Further, individuals who were in a committed relationship felt more desirable than those who were not. Concerning the cross-sectional stability of mate desirability across the lifespan, in men, short- and long-term desirability rose to the age of 40 and 50, respectively, and decreased afterward. In women, short-term desirability rose to the age of 38 and decreased afterward, whereas long-term desirability remained stable over time. Our results suggest that measuring long- and short-term self-perceived mate desirability reveals predictable correlates.

The potentially conflicted evaluations of others based on their intelligence.

Individual differences in intelligence are apparent and likely to come with important interpersonal consequences. We examined (N = 476) how (manipulated) individual differences in intelligence affect likability ratings of men and women. We found that (1) ratings were generally more favorable than unfavorable, (2) the difference between favorable and unfavorable ratings of the female target differed more than those same evaluations of the male target, (3) the favorable evaluation tendency was present across relative intelligence but weakest when the target was smarter than the participant, (4) the smarter target was rated more unfavorably, and (5) the equally smart target was rated more favorably than the less intelligent target. Results suggest that people are somewhat conflicted in their evaluations of those smarter than they are whereas similarly and less intelligent people presented less of an apparent conflict in evaluations.

Associations Between Motives for Casual Sex, Depression, Self-Esteem, and Sexual Victimization.

People's motives for casual sex moderate associations between their sexual behavior and the outcomes they experience. Derived from self-determination theory, autonomous motives for casual sex (e.g., I wanted the fun and enjoyment) and non-autonomous motives (e.g., I wanted to please someone else) correlated in previous research differentially with measures of well-being and incidence of casual sex. In a sample of American college students (N = 284), we replicated these prior findings and extended them as follows: autonomous and non-autonomous motives for sex were correlated with two measures of casual sex (i.e., the three behavior questions from the Sociosexual Orientation Inventory; the number of partners with whom participants had penetrative sex but did not wish to become emotionally involved); two measures of well-being (i.e., self-esteem, depression), and a measure of overall sexual victimization (i.e., a combined score from the Sexual Experiences Survey). We found that autonomous motives were more strongly associated with casual sexual behavior than were non-autonomous motives in both sexes. Autonomous motives were positively associated with sexual victimization in women but not in men. Compared to autonomous motives, sex for non-autonomous motives was linked to less self-esteem in both sexes, and with more depression and sexual victimization in women. Sex differences in associations between motives and victimization persisted even when the general effects of participant's sex and casual sex were controlled in hierarchical regressions. Our findings further revealed the importance of agency (or lack thereof) in predicting sexual behavior and psychological health.

Mate preference priorities in the East and West: A cross-cultural test of the mate preference priority model.

OBJECTIVE: Mate choice involves trading-off several preferences. Research on this process tends to examine mate preference prioritization in homogenous samples using a small number of traits and thus provide little insight into whether prioritization patterns reflect a universal human nature. This study examined whether prioritization patterns, and their accompanying sex differences, are consistent across Eastern and Western cultures. METHOD: In the largest test of the mate preference priority model to date, we asked an international sample of participants (N = 2,477) to design an ideal long-term partner by allocating mate dollars to eight traits using three budgets. Unlike previous versions of the task, we included traits known to vary in importance by culture (e.g., religiosity and chastity). RESULTS: Under low budget conditions, Eastern and Western participants differed in their mate dollar allocation for almost every trait (average d = 0.42), indicating that culture influences prioritization. Despite these differences, traits fundamental for the reproductive success of each sex in the ancestral environment were prioritized by both Eastern and Western participants. CONCLUSION: The tendency to prioritize reproductively fundamental traits is present in both Eastern and Western cultures. The psychological mechanisms responsible for this process produce similar prioritization patterns despite cross-cultural variation.

Country-level correlates of the Dark Triad traits in 49 countries.

OBJECTIVES: The Dark Triad traits (i.e., narcissism, psychopathy, Machiavellianism) capture individual differences in aversive personality to complement work on other taxonomies, such as the Big Five traits. However, the literature on the Dark Triad traits relies mostly on samples from English-speaking (i.e., Westernized) countries. We broadened the scope of this literature by sampling from a wider array of countries. METHOD: We drew on data from 49 countries (N = 11,723; 65.8% female; AgeMean  = 21.53) to examine how an extensive net of country-level variables in economic status (e.g., Human Development Index), social relations (e.g., gender equality), political orientations (e.g., democracy), and cultural values (e.g., embeddedness) relate to country-level rates of the Dark Triad traits, as well as variance in the magnitude of sex differences in them. RESULTS: Narcissism was especially sensitive to country-level variables. Countries with more embedded and hierarchical cultural systems were more narcissistic. Also, sex differences in narcissism were larger in more developed societies: Women were less likely to be narcissistic in developed (vs. less developed) countries. CONCLUSIONS: We discuss the results based on evolutionary and social role models of personality and sex differences. That higher country-level narcissism was more common in less developed countries, whereas sex differences in narcissism were larger in more developed countries, is more consistent with evolutionary than social role models.

Who complies with the restrictions to reduce the spread of COVID-19?: Personality and perceptions of the COVID-19 situation.

In 2020, many countries around the world created and enforced heavy restrictions geared towards reducing the spread of the coronavirus (i.e., COVID-19). In this study (N = 263), we examined the role of personality traits (i.e., Big Five and Dark Triad) and individual differences in perceptions of the COVID-19 pandemic situation (the situational eight: Duty, Intellect, Adversity, Mating, Positivity, Negativity, Deception, and Sociality) in accounting for individual differences in compliance with the governmental restrictions in Poland. We found that the way people perceived the situation explained more variance in compliance than personality traits which is in accordance with the hypothesis that strong situations, such as the COVID-19 pandemic, leave less room for dispositional tendencies in predicting behaviors than situational cues. Moreover, people scoring low on agreeableness and high on aspects of the Dark Triad traits (i.e., Machiavellianism, psychopathy Factor 1, and narcissistic rivalry) were less likely to comply with the restrictions. Additionally, we replicated and extended what is known about the associations between personality and individual differences in the perception of situations when the latter were assessed in relation to a strong situation and the former were assessed with long and multidimensional measures.

Adaptive and maladaptive behavior during the COVID-19 pandemic: The roles of Dark Triad traits, collective narcissism, and health beliefs.

In a nationally representative sample from Poland (N = 755), we examined the relationships between the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) and collective narcissism (i.e., agentic and communal) on the one hand, and behaviors related to the COVID-19 pandemic at (1) the zero-order level, at (2) the latent variance level, and (3) indirectly through health beliefs about the virus (i.e., the health belief model) on the other. We focused on preventive and hoarding behaviors as common reactions toward the pandemic. Participants characterized by the Dark Triad traits engaged less in prevention and more in hoarding, whereas those characterized by collective narcissism engaged in more hoarding only. Coronavirus-related health beliefs mediated patterns of prevention (fully) and hoarding (partially) in the latent Dark Triad (Dark Core) and collective narcissism. However, specific beliefs worked in opposite directions, resulting in a weak indirect effect for prevention and a null indirect effect for hoarding. The results point to the utility of health beliefs in predicting behaviors during the pandemic, explaining (at least in part) problematic behaviors associated with the dark personalities (i.e., Dark Triad, collective narcissism).

The Exploitive Mating Strategy of the Dark Triad Traits: Tests of Rape-Enabling Attitudes.

The Dark Triad traits have been repeatedly labeled as facilitating an exploitive mating strategy. However, various researchers have repeatedly conflated short-term mating or casual sex with an exploitive mating strategy. In this study using Mechanical Turk participants (N = 252; 142 men, 110 women), we provided a better test of just how sexually exploitive those high on the Dark Triad traits might be by examining how the traits related to rape-enabling attitudes. We examined how each trait may facilitate rape, whether these associations were robust to partialing the variance associated with the Big Five traits and similar in men and women, and showed that one reason why men may be more likely to rape than women is they are characterized by the Dark Triad traits more than women are. In so doing, we test the confluence model of rape that asserts that personality traits similar to the Dark Triad traits act as one pathway to rape.

Where the psychological adaptations hit the ecological road.

We argue that the target authors focus too much on adaptive behavioral responses and not enough on actual psychological adaptations. We suggest the Dark Triad traits may represent facultative, psychological adaptations sensitive to seasonal variance and food shortages. We document that shorter distances from the equator are linked to higher national narcissism levels, whereas longer distances are associated with higher national-level machiavellianism. Dark Triad traits may serve as critical survival mechanisms when prioritizing oneself over and/or at the cost of others.

An Examination of the Nature of Erotic Talk.

Using a mixed-methods study, we provided the first systematic documentation and exploration of erotic talk. In Study 1 (N = 95), participants provided 569 erotic talk statements in an anonymous online survey, which we classified, using a modified thematic analysis, as being representative of eight themes. In Study 2 (N = 238), we quantified individual differences in these themes, subjected them to factor analysis, and examined the nomological network surrounding them with measures of relationship and sexual satisfaction, sociosexuality, and personality. The eight initial categories represented two higher order factors, which we call individualist talk and mutualistic talk. These factors were orthogonal in factor analysis and distinct in their nomological network. While the majority of people reported using erotic talk, we found few sex differences in its use.

The Brief Aggression Questionnaire: Structure, Validity, Reliability, and Generalizability.

In contexts that increasingly demand brief self-report measures (e.g., experience sampling, longitudinal and field studies), researchers seek succinct surveys that maintain reliability and validity. One such measure is the 12-item Brief Aggression Questionnaire (BAQ; Webster et al., 2014), which uses 4 3-item subscales: Physical Aggression, Verbal Aggression, Anger, and Hostility. Although prior work suggests the BAQ's scores are reliable and valid, we addressed some lingering concerns. Across 3 studies (N = 1,279), we found that the BAQ had a 4-factor structure, possessed long-term test-retest reliability across 12 weeks, predicted differences in behavioral aggression over time in a laboratory experiment, generalized to a diverse nonstudent sample, and showed convergent validity with a displaced aggression measure. In addition, the BAQ's 3-item Anger subscale showed convergent validity with a trait anger measure. We discuss the BAQ's potential reliability, validity, limitations, and uses as an efficient measure of aggressive traits.

The brief aggression questionnaire: psychometric and behavioral evidence for an efficient measure of trait aggression.

A key problem facing aggression research is how to measure individual differences in aggression accurately and efficiently without sacrificing reliability or validity. Researchers are increasingly demanding brief measures of aggression for use in applied settings, field studies, pretest screening, longitudinal, and daily diary studies. The authors selected the three highest loading items from each of the Aggression Questionnaire's (Buss & Perry, 1992) four subscales--Physical Aggression, Verbal Aggression, anger, and hostility--and developed an efficient 12-item measure of aggression--the Brief Aggression Questionnaire (BAQ). Across five studies (N = 3,996), the BAQ showed theoretically consistent patterns of convergent and discriminant validity with other self-report measures, consistent four-factor structures using factor analyses, adequate recovery of information using item response theory methods, stable test-retest reliability, and convergent validity with behavioral measures of aggression. The authors discuss the reliability, validity, and efficiency of the BAQ, along with its many potential applications.

Four functions for four relationships: consensus definitions of university students.

In this study (N = 192; 124 women, 68 men), consensus definitions of one-night stands, booty-call relationships, friends-with-benefits, and serious romantic relationships were fashioned using a sample of university students. Participants provided a Likert and forced-choice assessment of how each relationship was characterized by the functions of sexual gratification, trial run, placeholder, and socioemotional support. Serious romantic relationships were primarily used to gain socioemotional support. Friends-with-benefits relationships were motivated by seeking a placeholder until someone better came along and as a trial run for a more serious relationship. Booty-call relationships and one-night stands were motivated primarily by a desire for sexual gratification. Men ascribed a greater range of reasons to engage in sexual relationships than women did and the more short-term the relationship was in nature, the greater the emergence of sex differences in ascribed functions.

Intimate Partner Cyberstalking: Exploring Vulnerable Narcissism, Secondary Psychopathy, Borderline Traits, and Rejection Sensitivity.

Intimate partner cyberstalking refers to the monitoring and controlling of an intimate partner through technologies. Unlike the cyberstalking of strangers, less is known about the motives and perpetration of intimate partner cyberstalking. In this study, we explore how vulnerable narcissism, secondary psychopathy, and borderline traits (i.e., the "Vulnerable Dark Triad") and rejection sensitivity relate to the perpetration of intimate partner cyberstalking. Participants (N = 278; 58 percent women) were recruited through social media and completed an anonymous online questionnaire. Positive correlations were observed between vulnerable narcissism, secondary psychopathy, borderline traits, rejection sensitivity, and intimate partner cyberstalking. Borderline traits moderated the relationship between participant sex (men and women) and intimate partner cyberstalking, and women with high borderline traits were most likely to cyberstalk intimate partners. Lastly, there was a significant indirect effect of vulnerable narcissism on intimate partner cyberstalking through rejection sensitivity. These findings highlight the importance of relational insecurity and rejection sensitivity in intimate partner cyberstalking and provide useful directions for future research exploring cyberstalking behaviors in intimate relationships.

Self-selection biases in psychological studies: Personality and affective disorders are prevalent among participants.

Respondents select the type of psychological studies that they want to participate in consistence with their needs and individual characteristics, which creates an unintentional self-selection bias. The question remains whether participants attracted by psychological studies may have more psychological dysfunctions related to personality and affective disorders compared to the general population. We investigated (N = 947; 62% women) whether the type of the invitation (to talk about recent critical or regular life events) or the source of the data (either face-to-face or online) attracts people with different psychopathology. Most importantly, participants who alone applied to take part in paid psychological studies had more symptoms of personality disorders than those who had never before applied to take part in psychological studies. The current results strongly translate into a recommendation for either the modification of recruitment strategies or much greater caution when generalizing results for this methodological reason.

Narcissus' belief about his body: Aspects of narcissism, body image, and eating disorder symptoms.

OBJECTIVE: Narcissism may play a role in shaping body image concerns. Here we examined the relationships between narcissism (i.e., agentic extraversion, antagonism, narcissistic neuroticism, leadership/authority, exhibitionism/entitlement) and body image concerns and disturbances (i.e., drive for thinness, drive for muscularity, eating disorder symptoms, body mass index, current/desired fat, and current/desired muscularity). METHODS: Mechanical Turk workers from the USA (N = 430; 64% male) completed the Narcissistic Admiration and Rivalry Questionnaire, the Hypersensitive Narcissism Scale, the Narcissistic Personality Inventory, the Drive for Muscularity Scale, the Drive for Thinness Scale, the Eating Disorder Examination Questionnaire-Short, and the Sex-Specific Somatomorphic Matrixes. RESULTS: All narcissistic factors were associated with a greater drive for thinness (except for leadership/authority) and for muscularity, more eating disorder symptoms, a greater desired body fat (except for leadership/authority), and a greater current muscularity. Greater agentic extraversion and exhibitionism/entitlement were associated with lower levels of current body fat, and greater antagonism was associated with a greater desired muscularity. DISCUSSION: Notably, individual differences in narcissism appeared to be important in understanding body image concerns, broadly speaking. We found that narcissism may be associated with body image concerns among both sexes differently, and especially that drive for thinness was more related to narcissism in men. Our results emphasize the importance of narcissism in formulating and treating body image-related disorders for both men and women. Ultimately, narcissistic features of personality may be risk factors for developing and perpetuating body image concerns, and therefore should be considered in assessment, formulation, diagnosis, and treatment of eating disorders.

More than just a pretty face and a hot body: multiple cues in mate-choice.

Mate preferences have been well studied in social and evolutionary psychology. In two studies (N = 490), using two different measurement techniques, we examined mate preferences for the body and the face in the context of other traits. Results replicated prior research on mate preferences across the sex of the participant and mating duration but clarified the nature of preferences for physical attractiveness. Generally, physical attractiveness was a necessity in short-term mating and for men and traits like kindness were a necessity in long-term mating and for women. Men wanted a short-term mate who had a good body, likely because that body advertises fertility whereas both sexes wanted a mate with a nice face for a long-term mate, which is likely because the face is a cue based on structural properties related to health. Sex and mating-duration differences on preferences for attractive faces and bodies were robust to differences in measurement technique.
