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.

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.

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.

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.

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.

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.

To see or not to see (again): Dealbreakers and dealmakers in relation to social inclusion.

In this study, we replicated what is known about the relative importance of dealbreakers (i.e., traits avoided) and dealmakers (i.e., traits sought) in romantic and sexual relationships and extended it to an examination of self-reports of mate value, self-esteem, and loneliness. In two experiments (N = 306; N = 304) we manipulated the information people were told about potential partners and asked them about their intentions to have sex again with or go on a second date with opposite sex targets. People were less interested in partners after learning dealbreakers, effects which operated more strongly in the long-term than short-term context, but similarly in men and women. People who reported less self-esteem or more loneliness were more receptive to people with dealbreakers. People who thought they had more mate value, more self-esteem, or less loneliness were more receptive to dealmakers. Results are discussed using sociometer, prospect, and sexual strategies theories.

Variation in depressive symptom trajectories in a large sample of couples.

The occurrence of depression is influenced by social relationships, however, most studies focus on individuals, not couples. We aimed to study how depressive symptoms of couples evolve over time and determine, which characteristics are associated with their distinct trajectories. A multi-centric cohort sample of 11,136 heterosexual couples (mean age = 60.76) from 16 European countries was followed for up to 12 years (SHARE study). Information on depressive symptoms measured by EURO-D scale was collected every 2 years. Dyadic growth mixture modeling extracted four distinct classes of couples: both non-depressed (76.91%); only women having consistently high depressive symptoms while men having consistently low depressive symptoms (8.08%); both having increasing depressive symptoms (7.83%); and both having decreasing depressive symptoms (7.18%). Couples with increasing depressive symptoms had the highest prevalence of relationship dissolution and bereavement. In comparison to the nondepressed class, individuals with any depressive symptoms were less psychologically and physically well. Our results suggest that distinct mechanisms are responsible for couples' various longitudinal trajectories of depressive symptoms.

Being More Educated and Earning More Increases Romantic Interest: Data from 1.8 M Online Daters from 24 Nations.

How humans choose their mates is a central feature of adult life and an area of considerable disagreement among relationship researchers. However, few studies have examined mate choice (instead of mate preferences) around the world, and fewer still have considered data from online dating services. Using data from more than 1.8 million online daters from 24 countries, we examined the role of sex and resource-acquisition ability (as indicated by level of education and income) in mate choice using multilevel modeling. We then attempted to understand country-level variance by examining factors such as gender equality and the operational sex ratio. In every nation, a person's resource-acquisition ability was positively associated with the amount of attention they received from other site members. There was a marked sex difference in this effect; resource-acquisition ability improved the attention received by men almost 2.5 times that of women. This sex difference was in every country, admittedly with some variance between nations. Several country-level traits moderated the effects of resource-acquisition ability, and in the case of unemployment this moderating role differed by sex. Overall, country-level effects were more consistent with evolutionary explanations than sociocultural ones. The results suggest a robust effect of resource-acquisition ability on real-life mate choice that transcends international boundaries and is reliably stronger for men than women. Cross-cultural variance in the role of resource-acquisition ability appears sensitive to local competition and gender equality at the country level.

The fear of COVID-19 scale: Its structure and measurement invariance across 48 countries.

Coronavirus disease (COVID-19) has been a source of fear around the world. We asked whether the measurement of this fear is trustworthy and comparable across countries. In particular, we explored the measurement invariance and cross-cultural replicability of the widely used Fear of COVID-19 scale (FCV-19S), testing community samples from 48 countries (N = 14,558). The findings indicate that the FCV-19S has a somewhat problematic structure, yet the one-factor solution is replicable across cultural contexts and could be used in studies that compare people who vary on gender and educational level. The validity of the scale is supported by a consistent pattern of positive correlations with perceived stress and general anxiety. However, given the unclear structure of the FCV-19S, we recommend using latent factor scores, instead of raw scores, especially in cross-cultural comparisons.

Leaving without a word: Ghosting and the Dark Triad traits.

Researchers have extensively explored the early and middle stages of romantic and sexual relationships for those high on the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) but they have generally missed the termination stage of relationships. In this study we examined (N = 341) the role these traits play in one termination strategy, ghosting. Ghosting is when a person discontinues a relationship through silence; it is considered an indirect form of relationship termination. We found that (1) those who reported ghosting someone in the past (vs. those who did not) found ghosting to be acceptable and were more Machiavellian and psychopathic, (2) ghosting was most acceptable in the short-term (vs. long-term) context especially for those who had previously ghosted someone, and (3) those high in the Dark Triad traits rated ghosting more acceptable to terminate short-term relationships, but not long-term ones. We also found that the correlations between acceptability and ghosting short-term partners and the Dark Triad traits was localized to narcissistic men with a similar-yet-weak effect for psychopathy. Results are discussed in relation to how ghosting may be primarily committed by people who are interested in casual sex where investment is low and may be part of the fast life history strategies linked to the Dark Triad traits.

Why Do People Watch Porn? An Evolutionary Perspective on the Reasons for Pornography Consumption.

We investigated the reasons for pornography consumption using a bottom-up approach (i.e., open-ended questionnaire) and proposed that those reasons would reflect a short-term mating orientation of individuals that watch pornography and a strategy that should help them to attract or maintain potential mates easier (i.e., a fitness increasing strategies) by enhancing their sexual knowledge through pornography watching. In Study 1 (N = 276), relying on an open-ended questionnaire and a content analysis, we identified 78 reasons for why people claim to consume pornography. In Study 2 (N = 322), we grouped those reasons into categories using a series of factor analyses, resulting in four dimensions of reasons for watching pornography: (1) increased sex drive, (2) enhancing sexual performance, (3) social and instrumental reasons, and (4) lack of relational and emotional skills. The content of these factors supported the idea that the reasons for consuming pornography are reflections of a short-term mating orientation and a way to enhance their sexual knowledge and performance. Individuals with higher scores on the dimensions of reasons for pornography consumptions had higher scores on the Dark Triad traits and sociosexuality, mate-value and slow life history strategies (in the case of enhancing sexual performance dimension). In Study 3 (N = 327), we tested to what extent the factorial structure of the reasons for pornography consumption can be confirmed via Confirmatory factor analysis and tested the convergent validity of the reasons to consume pornography.

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.

Structure of Dark Triad Dirty Dozen Across Eight World Regions.

The Dark Triad (i.e., narcissism, psychopathy, Machiavellianism) has garnered intense attention over the past 15 years. We examined the structure of these traits' measure-the Dark Triad Dirty Dozen (DTDD)-in a sample of 11,488 participants from three W.E.I.R.D. (i.e., North America, Oceania, Western Europe) and five non-W.E.I.R.D. (i.e., Asia, Middle East, non-Western Europe, South America, sub-Saharan Africa) world regions. The results confirmed the measurement invariance of the DTDD across participants' sex in all world regions, with men scoring higher than women on all traits (except for psychopathy in Asia, where the difference was not significant). We found evidence for metric (and partial scalar) measurement invariance within and between W.E.I.R.D. and non-W.E.I.R.D. world regions. The results generally support the structure of the DTDD.

Academic dishonesty among university students: The roles of the psychopathy, motivation, and self-efficacy.

Academic dishonesty is a common problem at universities around the world, leading to undesirable consequences for both students and the education system. To effectively address this problem, it is necessary to identify specific predispositions that promote cheating. In Polish undergraduate students (N = 390), we examined the role of psychopathy, achievement goals, and self-efficacy as predictors of academic dishonesty. We found that the disinhibition aspect of psychopathy and mastery-goal orientation predicted the frequency of students' academic dishonesty and mastery-goal orientation mediated the relationship between the disinhibition and meanness aspects of psychopathy and dishonesty. Furthermore, general self-efficacy moderated the indirect effect of disinhibition on academic dishonesty through mastery-goal orientation. The practical implications of the study include the identification of risk factors and potential mechanisms leading to students' dishonest behavior that can be used to plan personalized interventions to prevent or deal with academic dishonesty.

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).

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.

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.

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.
