Poaching,promiscuity, and deceit: Combatting mating rivalry in same‐sex friendships

If humans faced recurrently over evolutionary history the adaptive problem of competition with same‐sex friends for mates, they may have evolved psychological mechanisms designed to prevent and combat mating rivalry with same‐sex friends. Four studies were conducted to test hypotheses about the design of these mechanisms. In Studies 1 and 2 (N= 406 and N= 342, respectively) we found that, as predicted, people experience more upset in response to imagined rivalry from a friend than from a stranger. In Study 3 (N= 455), in which a between‐subjects design was utilized, we found that women's, but not men's, willingness to become friends with a member of the same sex is lower when the person is described as sexually promiscuous. In Study 4 (N= 169) we found that people report being deceived by friends about mating rivalry more often than they themselves report engaging in deceit about rivalry, and women more than men deceive each other about how sexually experienced and promiscuous they are. Discussion addresses implications of the findings and the use of an evolutionary approach for understanding conflict in same‐sex friendship.     

Sex similarities and differences in preferences for short-term mates: what, whether, and why

Are there sex differences in criteria for sexual relationships? The answer depends on what question a researcher asks. Data suggest that, whereas the sexes differ in whether they will enter short-term sexual relationships, they are more similar in what they prioritize in partners for such relationships. However, additional data and context of other findings and theory suggest different underlying reasons. In Studies 1 and 2, men and women were given varying "mate budgets" to design short-term mates and were asked whether they would actually mate with constructed partners. Study 3 used a mate-screening paradigm. Whereas women have been found to prioritize status in long-term mates, they instead (like men) prioritize physical attractiveness much like an economic necessity in short-term mates. Both sexes also show evidence of favoring well-rounded long- and short-term mates when given the chance. In Studies 4 and 5, participants report reasons for having casual sex and what they find physically attractive. For women, results generally support a good genes account of short-term mating, as per strategic pluralism theory (S. W. Gangestad & J. A. Simpson, 2000). Discussion addresses broader theoretical implications for mate preference, and the link between method and theory in examining social decision processes.     

Evolved sex differences in the number of partners desired? The long and the short of it

Do men seek more short-term mates than women? Buss and Schmitt (1993) showed a pattern of mean difference in the ideal number of sexual partners men and women desired over various time frames. We replicated these mean sex differences (e.g., ideal number over the next 30 years: Ms = 7.69 and 2.78 for men and women, respectively), but in both data sets the sampling distributions were highly skewed. In Study 1, we found few sex differences in medians across time frames (e.g., ideal number over the next 30 years: Mdn = 1 for both men and women). In Study 2, most college men (98.9%) and women (99.2%) said they wanted to settle down with one mutually exclusive sexual partner at some point in their life, ideally within the next 5 years. Neither medians in number of partners desired overall before settling down (replicating Study 1) nor medians in short-term partners desired before settling down (Mdn = 0) differed significantly by gender. Rather, men and women concurred: Short-term mating is not what humans typically seek.     

System‐justifying behaviors: When feeling dependent on a system triggers gender stereotype‐consistent academic performance

Based on system‐justification theory, we hypothesized that men and women would perform in accordance with gender stereotypes mainly when justification of the system is necessary. In this research, system‐justification motivation was triggered using a system‐dependency manipulation. Study 1 shows that when feeling highly (vs. less) dependent on the system, people endorsed system‐justifying beliefs more. In Study 2, men performed better in math than in verbal domains, while women showed the reverse pattern, but only when they felt highly dependent on the system. Similar results were obtained on performance self‐evaluation. Copyright © 2016 John Wiley & Sons, Ltd.     

The mere presence of opposite-sex others on judgments of sexual and romantic desirability: opposite effects for men and women

Men's and women's mate preferences impose on each a unique set of adaptive problems that must be solved when judging the desirability of prospective mates. One potentially revealing source of information about an individual's desirability as a romantic partner is contained in the decisions made by same-sex others. The present studies predicted that men's and women's desirability assessments would be affected in opposite ways when target persons were depicted with members of the target's opposite sex. Study 1 (N = 847) documented that women rated men more desirable when shown surrounded by women than when shown alone or with other men (a desirability enhancement effect). In sharp contrast, men rated women less desirable when shown surrounded by men than when shown alone or with women (a desirability diminution effect) . Study 2 (N = 627) demonstrated similar sexually divergent effects for estimates of the desirability of same-sex competitors.     

Men's strategic preferences for femininity in female faces

Several evolutionarily relevant sources of individual differences in face preference have been documented for women. Here, we examine three such sources of individual variation in men's preference for female facial femininity: term of relationship, partnership status and self‐perceived attractiveness. We show that men prefer more feminine female faces when rating for a short‐term relationship and when they have a partner (Study 1). These variables were found to interact in a follow‐up study (Study 2). Men who thought themselves attractive also preferred more feminized female faces for short‐term relationships than men who thought themselves less attractive (Study 1 and Study 2). In women, similar findings for masculine preferences in male faces have been interpreted as adaptive. In men, such preferences potentially reflect that attractive males are able to compete for high‐quality female partners in short‐term contexts. When a man has secured a mate, the potential cost of being discovered may increase his choosiness regarding short‐term partners relative to unpartnered men, who can better increase their short‐term mating success by relaxing their standards. Such potentially strategic preferences imply that men also face trade‐offs when choosing relatively masculine or feminine faced partners. In line with a trade‐off, women with feminine faces were seen as more likely to be unfaithful and more likely to pursue short‐term relationships (Study 3), suggesting that risk of cuckoldry is one factor that may limit men's preferences for femininity in women and could additionally lead to preferences for femininity in short‐term mates.     

Gender differences in implicit gender self‐categorization lead to stronger gender self‐stereotyping by women than by men

It was hypothesized that, in natural group contexts, low‐status in‐group membership would be highly accessible, whereas membership to high‐status groups would not. Therefore, gender group membership was predicted to be more accessible for women than for men. It was further hypothesized that the high accessibility of gender group membership would lead to stronger self‐stereotyping for women than for men. To measure the accessibility of gender group membership, participants performed a Gender Self‐Categorization Implicit Association Test (Studies 1 and 2), measuring the strength of automatic associations between the self and the gender in‐group. Participants also performed a Self‐Stereotyping Implicit Association Test (Study 2), assessing the strength of automatic associations between the self and the stereotypical traits of the in‐group. As expected, implicit gender self‐categorization and implicit gender self‐stereotyping were stronger for women than for men. Importantly, implicit gender self‐categorization mediated the relation between gender and self‐stereotyping. Therefore, implicit gender self‐categorization was the mechanism underlying stronger implicit self‐stereotyping by women. Copyright © 2012 John Wiley & Sons, Ltd.     

Attraction to attachment insecurity: Flattery,appearance, and status's role in mate preferences

Research has shown that people select securely attached individuals as their first choice when asked to choose among secure or insecure partner prototypes. Despite this pattern, not everyone chooses a secure partner in real life. The goal of the reported studies was to examine factors that lead people to select insecure mates. Specifically, the roles of flattery, appearance, and status were assessed. In the first study, we found that flattery increased attraction to insecure partners. Study 2 showed that men preferred physical beauty over security. In Study 3, anxious women were attracted to high‐status insecure men. These findings help explain why people may sometimes end up with insecure partners despite their professed preference for secure companions.     

How Alluring Are Dark Personalities? The Dark Triad and Attractiveness in Speed Dating

Dark Triad traits (narcissism, psychopathy, and Machiavellianism) are linked to the pursuit of short‐term mating strategies, but they may have differential effects on actual mating success in naturalistic scenarios: Narcissism may be a facilitator for men's short‐term mating success, while Machiavellianism and psychopathy may be detrimental. To date, little is known about the attractiveness of Dark Triad traits in women. In a speed‐dating study, we assessed participants' Dark Triad traits, Big Five personality traits, and physical attractiveness in N = 90 heterosexual individuals (46 women and 44 men). Each participant rated each partner's mate appeal for short‐ and long‐term relationships. Across both sexes, narcissism was positively associated with mate appeal for short‐ and long‐term relationships. Further analyses indicated that these associations were due to the shared variance among narcissism and extraversion in men and narcissism and physical attractiveness in women, respectively. In women, psychopathy was also positively associated with mate appeal for short‐term relationships. Regarding mating preferences, narcissism was found to involve greater choosiness in the rating of others' mate appeal (but not actual choices) in men, while psychopathy was associated with greater openness towards short‐term relationships in women.

The dark triad: Facilitating a short‐term mating strategy in men

This survey (N = 224) found that characteristics collectively known as the Dark Triad (i.e. narcissism, psychopathy and Machiavellianism) were correlated with various dimensions of short‐term mating but not long‐term mating. The link between the Dark Triad and short‐term mating was stronger for men than for women. The Dark Triad partially mediated the sex difference in short‐term mating behaviour. Findings are consistent with a view that the Dark Triad facilitates an exploitative, short‐term mating strategy in men. Possible implications, including that Dark Triad traits represent a bundle of individual differences that promote a reproductively adaptive strategy are discussed. Findings are discussed in the broad context of how an evolutionary approach to personality psychology can enhance our understanding of individual differences.

Judging a Book by its Cover: The Influence of Implicit Self‐Theories on Brand User Perceptions

Do people judge others based on the brands they use? Prior research finds evidence to this effect, yet we argue this phenomenon is far from universal. Drawing on research on implicit self‐theories, we find that only entity (but not incremental) theorists are prone to judging people based on their brand use (Studies 1 and 2). We show that entity theorists infer that people use brands to signal who they are to others, thereby forming perceptions of these people based on the personality of the brands they use, but incremental theorists are reluctant to make inferences about brand users’ signaling motives (Studies 3, 4, and 5). When tendencies to make signaling inferences are reduced, entity theorists no longer judge people based on their brand use (Studies 3 and 4). Furthermore, even incremental theorists judge people based on their brand use when given the information that their brand use is not driven by situational forces, but is potentially driven by a signaling motivation (Study 5).     

Changes in women’s interpersonal styles across the menstrual cycle

Past research suggests that women alter their behaviors during periods of high fertility to attract mates. Consistent with this notion, the current research examined the interpersonal style, as defined by the interpersonal circumplex, men tend to find most attractive in potential mates and the change in women’s interpersonal styles across the menstrual cycle. In Study 1, a sample of 101 single men reported the interpersonal style they found most attractive in a potential mate. In Study 2, a sample of 86 women reported their interpersonal styles during each day of their menstrual cycle. Results indicated that men tended to prefer mates who were interpersonally warm and that women tended to become more interpersonally warm during periods of high fertility.     

Can men and women be just friends?

We tested evolution‐based hypotheses about (1) sex differences in perceived benefits and costs of opposite‐sex friendship and (2) differences in perceived benefits of same‐sex friendships and opposite‐sex friendships. In the Preliminary Study (N= 400), an act nomination procedure was used to identify the benefits and costs of same‐sex friendships and opposite‐sex friendships. In Study 1, a total of 231 participants (100 men, 131 women) evaluated the frequency of occurrence of 100 benefits and costs in their closest same‐sex friendship or opposite‐sex friendship. In Study 2, a total of 229 participants (92 men, 137 women) evaluated how beneficial and how costly each would be if it were to occur in their closest same‐sex friendship or opposite‐sex friendship. Results supported several key hypotheses. Men perceived sex with their opposite‐sex friends as more beneficial than did women. Women reported receiving protection from their opposite‐sex friends more often than did men, and they perceived the protection as highly beneficial. Both men and women reported receiving information from opposite‐sex friends about how to attract mates, and they perceived this information as beneficial. The discussion focuses on whether these benefits reflect an evolved psychology of opposite‐sex friendship, or instead are incidental by‐products.     

Right‐wing authoritarianism,societal threat to safety,and psychological distress

In two quasi‐experimental vignette studies, we have analyzed how societal threat to safety moderates the relation between right‐wing authoritarianism (RWA) and psychological distress. In Study 1 (Italian community sample, N = 343), we focused on depressive symptoms (measured with the Center for Epidemiologic Studies Depression Scale and the General Health Questionnaire). Two moderated regressions showed that the relation between RWA and both measures of depressive symptoms was positive and significant only among people exposed to a socially threatening scenario. In Study 2 (Italian student sample, N = 219), we focused on state anxiety and replicated Study 1's results. The findings indicated that, in conditions of societal threat to safety, RWA is a risk factor for psychological distress. Strengths, limitations, and possible developments of this research are discussed.     

Personality and Mate Preferences: Five Factors In Mate Selection and Marital Satisfaction

ABSTRACT Although personality characteristics figure prominently in what people want in a mate, little is known about precisely which personality characteristics are most important, whether men and women differ in their personality preferences, whether individual women or men differ in what they want, and whether individuals actually get what they want. To explore these issues, two parallel studies were conducted, one using a sample of dating couples (N= 118) and one using a sample of married couples (N= 216). The five-factor model, operationalized in adjectival form, was used to assess personality characteristics via three data sources—self-report, partner report, and independent interviewer reports. Participants evaluated on a parallel 40-item instrument their preferences for the ideal personality characteristics of their mates. Results were consistent across both studies. Women expressed a greater preference than men for a wide array of socially desirable personality traits. Individuals differed in which characteristics they desired, preferring mates who were similar to themselves and actually obtaining mates who embodied what they desired. Finally, the personality characteristics of one's partner significantly predicted marital and sexual dissatisfaction, most notably when the partner was lower on Agreeableness, Emotional Stability, and Intellect-Openness than desired.     

Perceiving Aggression from Facial Structure: Further Evidence for a Positive Association with Facial Width‐to‐Height Ratio and Masculinity,but not for Moderation by Self‐Reported Dominance

Recent work has indicated that individual differences in facial structure are linked to perceptions of aggressiveness. In particular, the relative width of a face [facial width‐to‐height ratio (fWHR)] has been suggested to be a reliable cue to aggressive behaviour, at least in men. Additionally, facial masculinity has been associated with perceptions of dominance, a close proxy of aggressiveness. In two studies, we assessed the robustness of this link using faces transformed along these vectors in men (Studies 1 and 2) and women (Study 2). Additionally, we examined whether individual differences in self‐reported dominance of perceivers moderated this association in order to extend previous work indicating that own dominance affects perception of such behaviour in others. Results indicated that both male and female faces with increased fWHR and increased facial masculinity were perceived as more aggressive. However, we found no systematic evidence for moderating effects of self‐reported dominance on the perception of aggression in others. Taken together, these results further support the robustness of fWHR and facial masculinity as cues to aggressiveness but question whether observers' own dominance moderates their perception of these cues in others.

How Implicit–Explicit Consistency of the Intelligence Self‐Concept Moderates Reactions to Performance Feedback

At present, it is not well understood which individual characteristics determine whether individuals will benefit or suffer from feedback about suboptimal performance. Three separate studies tested the idea that individuals' reactions to (neutral versus negative; positive versus negative) feedback as either improving or deteriorating performance in intelligence tests depended on their explicit and implicit self‐concept of intelligence (eSCI and iSCI). In all studies (Study 1, N = 177; Study 2, N = 165; Study 3, N = 132), persons with low eSCI/high iSCI showed a boost in performance after negative feedback, whereas persons with any other combination showed a decline in performance. The studies also provide an explanation for these effects in terms of mediating mechanisms. Whereas the performance boost of individuals with low eSCI/high iSCI can be best explained by achievement‐related reactance (Studies 2 and 3) and decrease in ruminative thinking (Study 3), the performance declines in the other configurations were mediated by decreased achievement motivation, increased frustration and increased outrage (Study 3). All these mediating mechanisms proved independent and incremental in a bootstrapping‐based moderated meditation analysis. The results are discussed in light of the construct validity of our Implicit Association Test (IAT) and IATs in general. Copyright © 2013 John Wiley & Sons, Ltd.     

Sex differences in the jealousy‐evoking effect of rival characteristics

Four studies examined sex differences in the jealousy‐evoking nature of rival characteristics. Study 1, among 130 undergraduates, made an inventory of all relevant rival characteristics that were spontaneously mentioned when asked about a rival to whom one's partner might feel attracted. On the basis of these findings, in Study 2, among 240 undergraduates, a questionnaire was constructed, containing 56 rival characteristics. A factor analysis distinguished five dimensions of rival characteristics, i.e. Social Dominance, Physical Attractiveness, Seductive Behaviors, Physical Dominance, and Social Status. In line with the predictions, men reported more jealousy when a rival was high in Social Dominance, Physical Dominance, and Social Status, whereas women reported more jealousy when a rival was high in Physical Attractiveness. Study 3 largely replicated these findings in a community sample of 144 heterosexuals. Study 4 showed that gay men (n = 80) reported more jealousy than lesbian women (n = 73) when the rival was high in Physical Dominance, and more jealousy than heterosexual men when the rival was high in Social Dominance. Lesbian women reported more jealousy than heterosexual women when the rival was high in Physical Attractiveness. In Studies 2–4, favorable rival characteristics evoked more jealousy among those high in Social Comparison Orientation, particularly among women. Copyright © 2002 John Wiley & Sons, Ltd.     

Collective Narcissism Predicts Hypersensitivity to In‐group Insult and Direct and Indirect Retaliatory Intergroup Hostility

Results of five studies (N = 1596) linked collective narcissism—a belief in in‐group exaggerated greatness contingent on external validation—to direct and indirect, retaliatory hostility in response to situations that collective narcissists perceived as insulting to the in‐group but which fell well beyond the definition of an insult. In Turkey, collective narcissists responded with schadenfreude to the European economic crisis after feeling humiliated by the Turkish wait to be admitted to the European Union (Study 1). In Portugal, they supported hostile actions towards Germans and rejoiced in the German economic crisis after perceiving Germany's position in the European Union as more important than the position of Portugal (Study 2). In Poland, they supported hostile actions towards the makers of a movie they found offensive to Poland (Studies 3 and 5) and responded with direct and indirect hostility towards a celebrity whose jokes about the Polish government they found offensive (Study 4). Comparisons with self‐positivity and in‐group positivity indices and predictors of intergroup hostility indicated that collective narcissism is the only systematic predictor of hypersensitivity to in‐group insult followed by direct and indirect, retaliatory intergroup hostility.

From dating to mating and relating: Predictors of initial and long‐term outcomes of speed‐dating in a community sample

We studied initial and long‐term outcomes of speed‐dating over a period of 1 year in a community sample involving 382 participants aged 18–54 years. They were followed from their initial choices of dating partners up to later mating (sexual intercourse) and relating (romantic relationship). Using Social Relations Model analyses, we examined evolutionarily informed hypotheses on both individual and dyadic effects of participants' physical characteristics, personality, education and income on their dating, mating and relating. Both men and women based their choices mainly on the dating partners' physical attractiveness, and women additionally on men's sociosexuality, openness to experience, shyness, education and income. Choosiness increased with age in men, decreased with age in women and was positively related to popularity among the other sex, but mainly for men. Partner similarity had only weak effects on dating success. The chance for mating with a speed‐dating partner was 6%, and was increased by men's short‐term mating interest; the chance for relating was 4%, and was increased by women's long‐term mating interest.
