Differential Reproductive Behavior Patterns Among the Dark Triad

Dark Tetrad at Work: Perceived Severity of Bullying, Harassment, and Workplace Deviance

Although the Dark Tetrad has been linked to deviant behaviors, more research is needed about its expression in workplaces and continuity outside of work. The current study investigated the role of the antagonistic traits on perception of workplace harassment and bullying. Men were found to score higher on antagonistic traits and have a more lenient perception of harassment and bullying. Personality traits at work and outside were highly correlated. Regression analyses revealed that sadism predicted a more lenient perception of bullying, while a more lenient perception of harassment was predicted by sadism and industry type, and partially by psychopathy and gender. In summary, personality traits enduring across environments, but sadism was the most important predictor of a more lenient perception of harassment and bullying at work. The current study suggests a disparity between personality traits and expressed behaviors. Findings can be used to prevent workplace deviance and aid recruitment processes.

The relationship between parental behavior and the reproductive strategy of daughter is mediated by the development of machiavellianism personality

Females who receive harsh, rejective, and inconsistent nurturing behavior from parents, are predicted to adopt mating strategies, such as short-term and unstable pair bonds with males. The speculation that, the rejective behavior a female receives during the early days, and their short-term mating strategy is mediated by the development of Machiavellianism personality, is not well confirmed. In this study, we investigated the relationship between parenting behavior, experienced by female college students (n = 168) in their early days, Machiavellianism personality, and behavior related to short-term reproductive strategy. The results revealed that, both maternal rejective behavior received by women in their childhood and Machiavellianism, have a relationship with the number of males that the female has ever romantically involved. Moreover, the mediation effect of Machiavellianism between maternal rejection in participants' childhood, and the number of males romantically involved, was marginally significant. This suggests that girls rejected by their mothers developed Machiavellianism. Consequently, this results in unstable female pair-bonding with the males.

Dark Traits, Harassment and Rape Myths Acceptances Among University Students

The convergence of Machiavellianism, narcissism, psychopathy and sadism is known as the "Dark Tetrad." Our understanding of the relationship between the Dark Tetrad, harassment and Rape Myths is limited. While men are more likely to blame victims of sexual violence, it is unclear how gender influences the ability to perceive harassment. The aim of the present study is to look at the relationship between dark traits, gender, Rape Myths and perception of harassment. A sample of N = 210 university students located in England & Wales were recruited on SONA and social media platforms. Student's t-tests, Pearson's correlations, and multiple linear regressions were conducted. Analyses revealed gender differences for both Rape Myths endorsement and perception of harassment. Furthermore, a relationship between the dark traits, Rape Myths and perception of harassment was founded. These results have several implications, including our ability to understand perpetrators' characteristics, the impact of the Dark Tetrad on Rape Myths and perception of harassment, and our ability to develop effective prevention programs.

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.

The effects of the Dark Triad personality traits on health protective behaviours: dyadic approach on self-reports and partner-reports

OBJECTIVE

The growing evidence show that romantic partners' personality traits mutually influence each other's health. The research on relationship between personality and health behaviours should include both partner's perspectives - relations between individuals' traits and their own outcomes (actor effects), and relations between individuals' traits and their partners' outcomes (partner effects). The objective of this study was to examine the actor and partner effects of the Dark Triad (DT) personality traits (psychopathy, Machiavellianism and narcissism) on the health protective behaviours (HPB) in romantic couples.

DESIGN

A convenience sample of 188 heterosexual romantic couples participated in a cross-sectional round-robin study. Three predictor measures were Self-Report Psychopathy Scale-III, Narcissistic Personality Inventory and MACH-IV inventory, whereas HPB inventory was used as criterion variable.

RESULTS

Data were analysed using the Actor-Partner Interdependence Model (APIM). The results suggest that men's psychopathy, and to a lesser extent men's Machiavellianism exert deleterious effects on their own and their partner's HPB. The majority of these effects replicated across both self-reports and partner-reports. Women's DT traits exerted weaker actor and partner effects on the HPB than men's DT traits.

CONCLUSIONS

Findings show that men's psychopathy and Machiavellianism have detrimental effects on their own as well as their partner's HPB.

Examining the Short Dark Tetrad (SD4) Across Models, Correlates, and Gender

To date, no studies have examined a range of structural models of the interpersonally aversive traits tapped by the Short Dark Tetrad (SD4; narcissism, Machiavellianism, psychopathy, sadism), in conjunction with their measurement invariance (males vs. females) and how the models each predict external correlates. Using a large sample of young adults (N = 3,975), four latent variable models were compared in terms of fit, measurement invariance, and prediction of intrapersonal and interpersonal functioning. The models tested were as follows: (Model A) confirmatory factor analytic, (Model B) bifactor, (Model C) exploratory structural equation model, and (Model D) a reduced-item confirmatory factor analytic that maximized item information. All models accounted for item covariance with good precision, although differed in incremental fit. Strong invariance held for all models, and each accounted similarly for the external correlates, highlighting differential predictive effects of the SD4 factors. The results provide support for four theoretically distinct but overlapping dark personality domains.

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).

Dark Triad Traits and Mate Retention Behaviors in Romantic Couples: The Actor-Partner Interdependence Model

By using actor-partner interdependence modeling (APIM), we examined the effects of the Dark Triad traits, psychopathy, narcissism, and Machiavellianism on two mate retention (MR) domains, cost-inflicting (C-I B) and benefit-provisioning behaviors (B-P B) as well as overall mate retention (OMR) on the sample of 100 heterosexual romantic couples. These effects were examined first without and then with the control of the overlap between the traits. The results show that actor effects of the Dark Triad traits on MR were stronger in men, and regarding partner effects, the Dark Triad traits in men exerted more frequent MR in women than women's Dark Triad traits in men. In line with our prediction, psychopathy had the strongest actor and partner effects on MR behaviors, both in men and women. Considering MR domains, we found actor effects on C-I B only in men, whereas actor effects on B-P B in both men and women. The Dark Triad traits, especially in men, exerted stronger partner effects on C-I B than on B-P B domain. Almost all actor and partner effects of psychopathy and narcissism remained significant after the control for the overlap between the traits, whereas all actor effects of Machiavellianism became nonsignificant. In both sets of analyses, without and with the control for the overlap between these traits, the most frequent plausible dyadic patterns were actor-only and couple pattern.

Mate value discrepancies, the Dark Triad and relationship satisfaction: A Euclidean distances approach

We used a Euclidean algorithmic method of calculating mate value discrepancies to test the hypothesis that mate value discrepancies would mediate a negative association between the Dark Triad and relationship satisfaction. Participants (N = 211) rated themselves, their partner, and their ideal partner on a set of traits known to be important in mate selection. They also completed Dark Triad and relationship satisfaction measures. We found an indirect, negative association between the Dark Triad and relationship satisfaction mediated by the Partner-Potential Partner mate value discrepancy. The higher on the Dark Triad, the more alternative partners there were that were closer to the participant's ideal mate preferences than their current partner, which was associated with decreased relationship satisfaction. This study contributes to our understanding of how the Dark Triad relates to mating psychology. These findings also highlight the utility of employing a Euclidean algorithm to understand associations between individual differences and relationship outcomes.
