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

When Kinks Come to Life: An Exploration of Paraphilic Behaviors and Underlying Predictors

Paraphilia is defined as a condition in which sexual excitement relies on fantasizing about and/or participating in unusual sexual behavior. Although recent studies have assessed the concordance between paraphilic interests and paraphilic behaviors, few studies have studied which individual traits and demographics predict engaging in paraphilic behaviors, or the level of concordance between arousal and behavior. The current study replicated and expanded Joyal and Carpentier's 2022 study. We assessed concordance between paraphilic arousal and behavior. Further, we assessed the impact of Dark Tetrad traits, impulsivity, social desirability and demographic variables on engaging in paraphilic behaviors using self-report questionnaires in a sample from the general population and FetLife. Finally, we were interested in whether these individual differences moderated the concordance between arousal and behavior. Results indicated high concordance between paraphilic arousal and behavior for all paraphilias except pedophilia and hebephilia. Younger, male participants were more likely to engage in various paraphilias than women and older participants. Machiavellianism was linked with lower paraphilic behavior, particularly impulsive or risky ones. Psychopathy predicted engaging in more deviant or illegal paraphilias, whereas sadism only showed an association for engaging in frotteurism and narcissism was not a predictor for engaging in any paraphilia. For several paraphilias, individual traits moderated the effect of arousal on behavior. Implications of these findings and future directions are discussed.

Dating App Users: Interpersonal Styles and Self-Reported Mating Success

In this study (N = 495), dating apps were conceptualized as digital leks. We examined how interpersonal (narcissism, Machiavellianism, psychopathy), sexual (sociosexual attitudes, desires, and behavior), and search (satisficing, alternatives) styles relate to mating success through dating apps (dates and sex). Individuals with a faster life history strategy, particularly men high in psychopathy and sexual desires, report more mating success via dating apps. Women who were easier satisficed also experienced more Tinder-sex. These findings clarify the nuanced roles of sociosexuality facets in dating app success, enriching the discourse on digital mating behaviors. Using the life history framework, this research advances our understanding of how personality shapes real-world mating outcomes that originate in digital contexts.

Is the link between the Dark Tetrad and the acceptance of sexual violence mediated by sexual machismo?

Previous studies have established relationships between the Dark Tetrad traits and sexual violence and its acceptance through myths about this type of violence. Sexual violence is positively associated with machismo, with sexist beliefs having been found to be linked with the Dark Tetrad and with the acceptance of sexual violence. Using a community sample comprising 362 adults between the ages of 18 and 70 (M = 35.6, SD = 14.3) and three self-report measures, this cross-sectional study aimed to explore the mediating role of sexual machismo in the relationship between each of the Dark Tetrad traits and the acceptance of sexual violence, both in the overall sample and by gender, as well as whether a significant variance in this acceptance is explained by the "dark" traits, sexual machismo, and gender. In the regression, sexual machismo (the male) gender, and only Machiavellianism were uniquely associated with the acceptance of sexual violence, and sexual machismo partially mediated the associations between the Dark Tetrad and the acceptance of sexual violence. These findings indicate that being male and higher in sexism is more closely linked with the acceptance of sexual violence than most Dark Tetrad traits. Moreover, the associations between the Dark Tetrad, sexual machismo, and the acceptance of sexual violence were stronger in men, consistent with the notion that these traits facilitate a "male" exploitive mating strategy, which likely also extends to victim-blaming and positive attitudes about sexual violence more broadly. Lastly, the results emphasize the pervasiveness of beliefs about male superiority over women and its relationship with victim-blaming even in women.

Men's Psychopathy and Mating Effort in Intimate Relationships: Links with Jealousy and Sexual Coercion

Psychopathic men sometimes direct sexual aggression toward prospective female partners (e.g., using sexually aggressive behavior on a first date) and such behavior may be indicative of a high mating effort strategy. Less research has investigated the role of psychopathy in men's use of sexually coercive behaviors in their intimate relationships (e.g., sexual aggression directed toward one's long-term romantic partner) or the relationship processes that might facilitate such behavior. The present study surveyed 143 heterosexual dyads to assess men's psychopathic traits and their relation to self-reports and partner-reports of men's jealousy and partner sexual coercion. Results across informant models showed that men's psychopathy was associated with higher suspicious jealousy and partner sexual coercion. Suspicious jealousy also indirectly linked men's psychopathic traits with engaging in partner sexual coercion. The findings provide novel insights using dyadic data and suggest that both psychopathy and jealousy are important for men's engagement in partner sexual coercion.

Bad parents? evaluating judgements of infant homicides

While the killing of one's own infant is an undoubtedly harrowing crime, there exists little research exploring attitudes toward these individuals. Such work has focused primarily on depictions of mothers, yet U.K. government data indicate that the majority of infant homicide cases involve paternal suspects. A sample of U.K. residents (n = 245) participated in a mixed-methods design to explore attitudes toward mothers and fathers who have been accused of murdering their infant child and whether parental mental health issues impacted these judgements. Results aligned with the chivalry hypothesis wherein maternal suspects were evaluated more leniently. Qualitative analyses uncovered hidden gender expectations: mothers were ascribed blame when the father was accused of infant homicide, a finding that was not present in the reverse scenario. This suggests that traditional views of motherhood conflict with a shifting social landscape that is seeing an increase in stay-at-home fathers and working mothers.

Barriers to Bystander Intervention in Sexual Harassment: The Dark Triad and Rape Myth acceptance in Indonesia, Singapore, and United Kingdom

Bystanders have an important role in preventing sexual violence, but they are often reluctant to intervene due to a range of barriers. In this study, we investigated relationships between the Dark Triad of personality (i.e. psychopathy, Machiavellianism and narcissism), rape myth acceptance and five bystander barriers. We addressed the paucity of research by collecting data from three countries (Indonesia, Singapore, and United Kingdom). In total, 716 University staff and students participated in an online survey. We found very few country-level differences in the correlations between the variables. In regression analyses, Machiavellianism and rape myth acceptance both had significant, positive relationships with failure to identify risk, failure to take responsibility, skills deficits and audience inhibition. Narcissism and psychopathy were significantly, negatively associated with audience inhibition and skills deficits. Findings indicate similarity in predictors of perceived barriers to bystander intervention across the three countries.

Dark Tetrad, Acceptance of Sexual Violence, and Sexism

Abstract. The Dark Tetrad is a cluster of four “dark” personality traits which are socially aversive, with distinct conceptual roots, but which are intercorrelated: narcissism, psychopathy, Machiavellianism, and sadism. Narcissism is associated with inflated self-esteem and feelings of grandiosity; psychopathy involves reduced empathy and a lack of remorse or guilt; Machiavellianism is characterized by a tendency for manipulation for own personal benefit; sadism involves feelings of pleasure with the pain or suffering of others. Sexism is the group of beliefs linked with the perceived superiority of men over women. Previous studies have found relationships between the Dark Tetrad and the tolerance of the use of sexual violence and between the former and sexism. Furthermore, sexism has been linked with the acceptance of sexual violence. This study aims to revise the literature exploring the link between each of the components of the Dark Tetrad and the legitimation of the use of sexual violence; it also aims to present the associations that have been found between the aforementioned variables and sexism and related concepts, in multiple studies. Based on the previous literature, suggestions for aims of future research in this field (i.e., Dark Tetrad, sexual violence, sexism) are made, more specifically exploring the relative effect of each of the components of the Dark Tetrad in the explanation of the legitimation of sexual violence, as well as exploring a possible, at least partial, mediation of sexism in the link between each of the “dark” traits and the acceptance of sexual violence.

Falsification of the Sexual Experiences Questionnaire: No Evidence of Systemic Sexual Harassment in Academic STEM

Herein, the socio-psychological narrative of sexual harassment (SH) is critically evaluated. The notion of systemic SH in university departments of science, technology, engineering, and mathematics (STEM) is contradicted by the overwhelming (>90%) career satisfaction among female STEM academics. The Sexual Experiences Questionnaire (SEQ), central to the study of SH, inheres the nominalistic fallacy. SEQ usage deploys subjectivist methodologies, categorical ambiguity, the post hoc ergo propter hoc fallacy, and treats respondents as cyphers. Intercorrelation of SEQ factors reduces response statistics by 42%, while phase-space vector geometry indicates the SEQ does not measure SH. Personality analysis implies that serial abusers dominate the incidence of SH. The widespread notion that 20–25% of female college students suffer violent sexual assault rests on a misreading of published work. The 2016 Campus Climate Survey permits an upper limit estimate that 3.2% of female college students suffer rape at the hands of 4.3% of male student perpetrators, largely accompanied by drugs or alcohol. The 2018 National Academy (NAS) Report on sexual harassment in STEM exhibits negligent scholarship and carelessly generalizing statistics and may itself promote violation of the EEOC legal definition of SH. Despite instances of grievous sex-based abuse, there is no evidence that female STEM academics face systemic sexual harassment. Finally, evolutionary psychology and the social significance of personality provide a scientific understanding of SH.

Situational and Dispositional Factors in Rape Cognitions: The Roles of Social Media and the Dark Triad Traits

Previous research has established the importance of socially aversive personality traits (i.e., the Dark Triad) in rape cognitions (operationalized here as rape-supportive attitudes, rape victim empathy, and hostile masculinity). However, less is known about how sexist social media content influences attitudes toward rape cognitions depending on the personality of the individual. In an online experiment, after completing the Short Dark Triad-3 questionnaire, participants (N = 180) were primed with either sexist or neutral tweets, rating them for acceptability, humor, rudeness, and ignorance. Participants then completed scales for rape-supportive attitudes, victim empathy, and hostile masculinity. Sexist tweets were rated as significantly less acceptable and humorous, and more rude and ignorant than neutral tweets. However, those high in the Dark Triad found the sexist tweets as funny and acceptable. Overall, exposure to the sexist tweets did not increase rape cognitions. Moreover, the Dark Triad traits had similar significant, positive correlations with rape-supportive attitudes, victim blame, and hostile masculinity in both sexist and neutral tweet conditions. Multiple regression analyses (controlling for gender) revealed that psychopathy was the strongest positive predictor for increased rape cognitions. Findings suggest that short exposure to sexist social media content may not influence rape cognitions, but that dispositional factors such as psychopathy are more important.

The Dark Triad and Sexual Assertiveness Predict Sexual Coercion Differently in Men and Women

Sexual coercion is a global problem that has been studied widely with regard to various characteristics of the perpetrators. The Dark Triad of personality (i.e., narcissism, Machiavellianism, and primary and secondary psychopathy) has been indicated as an important predictor of coercive cognitions and behaviors. In this study, we report findings of an online study (N = 208), exploring the relationship between sexual coercion, the Dark Triad, and sexual assertiveness (i.e., strategies for achieving sexual autonomy). We found that the Dark Triad was a stronger predictor of sexual coercion in men than in women. In men, all the Dark Triad components were significantly, positively correlated with sexual coercion, and narcissism and Machiavellianism had significant, negative correlations with sexual assertiveness. In women, only narcissism had a significant, positive correlation with sexual coercion, and the Dark Triad traits were not correlated with sexual assertiveness. In regression analyses, controlling for shared variance between the predictor variables, high secondary psychopathy, and low sexual assertiveness emerged as significant predictors of coercion in men. Only narcissism was a significant positive predictor in women. We discuss the results with a reference to evolutionary Life History theory.

Longitudinal Associations Between Primary and Secondary Psychopathic Traits, Delinquency, and Current Dating Status in Adolescence

Many have examined the desirability and mate competition tactics of adults higher on psychopathy using cross-sectional data, but few have studied the longitudinal associations between the lower-order factors of psychopathy (e.g., primary and secondary psychopathy) with indices of mating behavior in adolescents. More work is also needed to unravel how psychopathic youth outcompete rivals for mates. Delinquency has long been associated with dating and sexual behavior in adolescents, which may help to explain the competitive success of youth higher in psychopathic traits in vying for mates. We used cross-lagged panel modeling with three waves of data from a randomly drawn sample of 514 Canadian adolescents who provided annual self-reports of primary and secondary psychopathy, delinquency, and dating involvement from Grades 10 to 12 (15-18 years of age). Constructs were temporally stable. Secondary psychopathy and delinquency had positive within-time correlations with current dating status in Grade 10. A cross-lagged pathway from delinquency to dating involvement was supported from Grade 10 to 11, which replicated from Grade 11 to 12. However, this effect was specific to boys and not girls. An indirect effect also emerged whereby secondary psychopathy in Grade 10 increased the likelihood of being in a dating relationship in Grade 12 via heightened delinquency in Grade 11.

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.

Darker deals? Male dark tetrad preferences for female sex worker services

The present study explored links between male Dark Tetrad personality traits (psychopathy, Machiavellianism, narcissism, sadism) and preferences for using outdoor and indoor female sex worker services. We also investigated the mediating effects of perceiving sex workers as deviant and as victims. Heterosexual males (N = 347) were recruited to take part in an online survey investigating personality and attitudes towards female sex workers. Path analyses revealed that psychopathy and sadism positively predicted preferences for outdoor but not indoor female sex services. Sex worker choice mediated positive links between narcissism and outdoor female sex worker preferences. Compared to indoor, outdoor sex services are associated with increased aggression and violence. Our findings highlight the importance of considering narcissism and particularly psychopathy and sadism when investigating individual male preferences for outdoor sex services that are being offered by particularly vulnerable women.

Factors predictive of sexual violence: Testing the four pillars of the Confluence Model in a large diverse sample of college men

This article focuses on the characteristics of sexually violent men who have not been convicted of a crime. The objective of this study was to test the four key interrelated pillars of the Confluence Model. The first key pillar posits the interaction of Hostile Masculinity and Impersonal Sex as core risk predictors. The second pillar entails a "mediated structure" wherein the impact of more general risk factors is mediated via those specific to aggression against women. The third pillar comprises a single latent factor underlying various types of sexual violence. The fourth pillar expands the core model by including the secondary risk factors of lower empathy, peer support, extreme pornography use, and participation in alcohol parties. An ethnically diverse sample of 1,148 male students from 13 U.S. colleges and universities completed a comprehensive survey that assessed the hypothesized risk factors and self-reported sexual violence, which included noncontact sexual offenses, contact sexual coercion, and contact sexual aggression. A series of multiple regression analyses were conducted before testing structural equation models. The results supported the integration of the four pillars within a single expanded empirical model that accounted for 49% of the variance of sexual violence. This study yielded data supporting all four key pillars. These findings provide information about non-redudant risk factors that can be used to develop screening tools, group-based and individually tailored psychoeducational and treatment interventions.

Dark Triad Traits and Perceptions of Sexual Harassment

Those high on Dark Triad traits (narcissism, Machiavellianism, primary and secondary psychopathy) are more likely to engage in sexual harassment and less likely to empathize with others. Few studies have, however, considered the impact of Dark Triad traits on perceptions of sexually aggressive behavior performed by others. The present study investigated the relationship between Dark Triad traits and perceptions of sexual harassment. Heterosexual women (N = 142) aged 18 to 50 years (M = 20.86, SD = 5.62) completed the NPI-16 (Narcissistic Personality Inventory), Mach IV, Levenson Self-Report Psychopathy Scale, and Sexual Harassment Attitudes Questionnaire. Standard multiple regressions were conducted to investigate the extent to which Dark Triad traits predicted victim and perpetrator blame and attitudes toward victim responses to sexual harassment. Primary psychopathy was the only significant individual predictor such that women with higher levels of the trait were more likely to blame the victim and less likely to blame the perpetrator. In addition, primary psychopathy was related to higher endorsement of victim compliance, and lower likelihood of supporting confrontation of the perpetrator.

Associations between Dark Triad and Ambivalent Sexism: Sex Differences among Adolescents

The Dark Triad traits (DT; Machiavellianism, psychopathy, and narcissism) have been repeatedly labeled as a constellation of traits that are characterized by a dishonest and self-focused approach to interpersonal relations. Personality psychologists suggest that these traits make some people more susceptible than others to intergroup bias, threat, and aggression. Thus, in order to delve into a psychological profile prone to accepting and justifying sexist attitudes, the aims of the current study were to analyze the presence of DT and sexist attitudes in a sample of 367 adolescents (M_age = 15.12, SD = 0.88; 50.1% males), find out the relationships that DT has with both hostile and benevolent sexism, and analyze the relevant differences between sexes in these relationships. The results indicated higher scores in DT and Ambivalent sexism for males. The correlations of Machiavellianism with psychopathy, and psychopathy with narcissism revealed significantly higher associations in males than females. The structural equation modeling of the bifactorial model, characterized by a global latent factor that encompasses the common characteristics of DT-along with the three specific factors of Machiavellianism, psychopathy, and narcissism-showed that the global latent factor of DT was related to both hostile and benevolent sexism in males and females. Singularly, narcissism was related to benevolent sexism in males, and psychopathy was related to hostile sexism in females. Finally, this research discusses the implications of these results on the implementation of positive models of interpersonal relationships in adolescence towards dating violence prevention.

The Dark Tetrad and Male Clients of Female Sex Work

Many scholars have investigated the attitudes, beliefs, motives, and behavior of male clients of female sex workers. However, few have examined individual differences in major dimensions of personality expressed by men who purchase prostitution compared to those who do not. Although several evolutionary psychologists have studied prostitution and those involved in sex work, to our knowledge, none have explicitly considered the utility of an evolutionary personality perspective in trying to understand why particular men pay for sex. In the current mini-review, following other researchers, prostitution is described principally as a form of short-term mating sought primarily by men. We argue that the socially aversive traits embodying the Dark Tetrad (narcissism, Machiavellianism, psychopathy, and sadism) may characterize certain male clients of female sex workers, particularly those consumers expressing the motives of desiring exciting and novel sex with women who are treated with contempt, perceiving prostitution in a business-like manner with little emotional involvement, and seeking to dominate and control sex workers who are viewed as vulnerable and subservient. The traits of the tetrad may also be more prevalent among men who purchase sex from female sex workers in outdoor (e.g., street prostitution) in comparison to indoor settings (e.g., escort agencies).

Entrepreneurial Intentions of Teams: Sub-Dimensions of Machiavellianism Interact With Team Resilience

Machiavellians are often seen as manipulative people who contribute negatively to teams and ventures. However, recent work has shown that Machiavellians can also cooperate and act in pro-social ways in a team context. Thus, some aspects of Machiavellianism might be conducive for teams and team members' intentions to start a business venture. Most studies in this area have failed to (a) assess the effect of Machiavellianism at the team level, (b) take into account the dimensional nature of Machiavellianism, and (c) assess moderators of these effects. We propose that the combination of Machiavellianism and resilience in teams predict team entrepreneurial intentions (EI). Moreover, we propose that different team level dimensions of Machiavellianism (amoral manipulation, desire for status, desire for control, distrust of others) are differentially related to EI. More specifically, we expect at the team level that amoral manipulation and desire for status are positively related to changes in EI (as teams high on these dimensions feel that they can use unethical practices that give them an advantage in being successful), whereas desire for control and distrust of others should be negatively related to changes in EI (as entrepreneurial teams usually work in less structured situations and need to closely work together). Furthermore, all sub-dimensions of Machiavellianism should interact positively with team resilience as resilience acts as a buffer that protects teams from potential negative effects of Machiavellianism. In a multi-wave study among newly formed teams engaged in entrepreneurship projects, controlling for psychopathy and narcissism, we found partial support for our hypotheses. Results supported our expectations for the "amoral manipulation" and "desire for control" sub-dimensions, but not for the "desire for status" and the "distrust of others" sub-dimensions of Machiavellianism, with distrust of others showing unexpectedly opposite effects. This study contributes to the literature by looking at the dimensions of Machiavellianism at the level of entrepreneurial teams in conjunction with the more positive team characteristic, resilience. Our results indicate that the relationship between Machiavellianism and EI is more complex than previously hypothesized, as the sub-dimensions are sometimes positively and sometimes negatively related to entrepreneurial intentions and interact with team-level resilience.

The Light vs. Dark Triad of Personality: Contrasting Two Very Different Profiles of Human Nature

While there is a growing literature on "dark traits" (i.e., socially aversive traits), there has been a lack of integration with the burgeoning research literature on positive traits and fulfilling and growth-oriented outcomes in life. To help move the field toward greater integration, we contrasted the nomological network of the Dark Triad (a well-studied cluster of socially aversive traits) with the nomological network of the Light Triad, measured by the 12-item Light Triad Scale (LTS). The LTS is a first draft measure of a loving and beneficent orientation toward others ("everyday saints") that consists of three facets: Kantianism (treating people as ends unto themselves), Humanism (valuing the dignity and worth of each individual), and Faith in Humanity (believing in the fundamental goodness of humans). Across four demographically diverse samples (N = 1,518), the LTS demonstrated excellent reliability and validity, predicting life satisfaction and a wide range of growth-oriented and self-transcendent outcomes above and beyond existing measures of personality. In contrast, the Dark Triad was negatively associated with life satisfaction and growth-oriented outcomes, and showed stronger linkages to selfish, exploitative, aggressive, and socially aversive outcomes. This exploratory study of the contrasting nomological networks of the Light vs. Dark Triad provides several ways forward for more principled and data driven approaches to explore both the malevolent and beneficent sides of human nature.

Love, Sex, and Personality Pathology: A Life History View of Personality Pathologies and Sociosexuality

Love and sex are fundamental needs of most people, yet little research has examined such aspects of life in relation to personality pathologies. We examined the associations between pathological personality traits (i.e., negative affectivity, disinhibition, antagonism, psychoticism, and detachment) and sociosexuality (i.e., short-term mating orientation, long-term mating orientation, and sexual behavior) among 702 university students. In addition, we examined the mediating role of life history speed and tested whether sex moderated the associations that these pathological personality traits had with sociosexuality. Detachment, antagonism, disinhibition, and psychoticism had positive associations with short-term mating interests and negative associations with long-term mating interests. Life history speed mediated the associations that detachment and disinhibition had with short-term mating orientation and long-term mating orientation. Although sex did moderate the association that negative affectivity had with previous sexual behavior, we found no evidence that these mediational processes differed between men and women. Results are discussed in terms of the way personality traits shape the sociosexuality of men and women using a life history paradigm.

Basic Values and the Dark Triad Traits

Abstract. In samples from America, Brazil, and Hungary (N = 937), we examined the associations between the Dark Triad traits (i.e., narcissism, psychopathy, and Machiavellianism) and individual differences in excitement (i.e., valuing personal enjoyment), promotion (i.e., valuing achievements), existence (i.e., valuing physical survival), suprapersonal (i.e., valuing abstract ideas), interactive (i.e., valuing social relationships), and normative (i.e., valuing cultural norms) values. The traits were associated with the values of excitement and promotion, psychopathy was associated with a diminished emphasis on existence, psychopathy and Machiavellianism were associated with limited interactive or normative values, whereas narcissism was associated with a greater emphasis on suprapersonal, interactive, and normative values. We also found that sex differences in psychopathy were mediated by individual differences in the existence and normative values. Results are discussed from a life history framework.

The Dark Triad and framing effects predict selfish behavior in a one-shot Prisoner's Dilemma

What causes us to display selfish behaviors? We explored the extent to which Dark Triad traits (sub-clinical psychopathy, narcissism, and Machiavellianism) support a selfish behavioral strategy. We related performance on a hypothetical Prisoner's Dilemma (an economic game that simulates a two-person social dilemma) to participants' (N = 1400) Dark Triad scores. Because contextual factors also impact selfish behaviors, we tested how framing (gain vs. loss; and social vs. nonsocial) shaped performance in the Prisoner's Dilemma. Participants with high Dark Triad scores were more likely to behave selfishly in the Prisoner's Dilemma. Participants were also most likely to betray their partner in loss-framed and non-socially framed contexts. These effects did not interact with Dark Triad scores. Our data are consistent with the view that seemingly negative personality traits (like those associated with the Dark Triad traits) that persist in the population may serve as evolutionarily adaptive behavioral strategies.
