A protean approach to social influence: Dark Triad personalities and social influence tactics

To avoid detection, those high on Dark Triad traits (i.e., narcissism, psychopathy, and Machiavellianism) may adopt a protean approach to interpersonal influence. We show the Dark Triad traits correlate with a number of unique tactics of influence (Study 1; N = 259). We show this protean approach was insensitive to differences in targets of manipulation (Study 2; N = 296). When forced to choose one tactic to solve different adaptive problems, the Dark Triad traits were correlated with unique tactical choices (Study 3; N = 268). We show these associations are generally robust to controlling for the Big Five and participants’ sex (Study 1 and 2). We discuss the theoretical implications of these findings for both life history and cheater-detection theories.     

Creatures of the night: Chronotypes and the Dark Triad traits

In this study (N = 263) we provide a basic test of a niche-specialization hypothesis of the Dark Triad (i.e., narcissism, psychopathy, and Machiavellianism). We propose that in order to best enact a “cheater strategy” those high on the Dark Triad traits should have optimal cognitive performance and, thus, have a night-time chronotype. Such a disposition will take advantage of the low light, the limited monitoring, and the lessened cognitive processing of morning-type people. The Dark Triad composite was correlated with an eveningness disposition. This link worked through links with the “darker” aspects of the Dark Triad (i.e., Machiavellianism, secondary psychopathy, and exploitive narcissism); correlations that were invariant across the sexes. While we replicated sex differences in the Dark Triad, we failed to replicate sex differences in chronotype, suggesting eveningness may not be a sexually selected trait as some have argued but is a trait under natural selective pressures to enable effective exploitations of conspecifics by both sexes.     

The emotional deficits associated with the Dark Triad traits: Cognitive empathy,affective empathy,and alexithymia

Volunteers (N = 322) in an online survey revealed the complex correlational patterns between the Dark Triad traits and two forms of “emotional deficiencies” (i.e., limited empathy and alexithymia) overall and in each sex. Each Dark Triad trait was associated with a unique pattern of emotional deficits. Psychopathy was correlated with limited overall empathy, difficulty describing feelings, and externally oriented thinking. Narcissism was associated with limited affective empathy and difficulty identifying feelings, whereas Machiavellianism was associated with externally oriented thinking. The Dark Triad mediated sex differences in empathy and externally oriented thinking. Structural Equation Modeling suggests that the differential facets of alexithymia predict different forms of limited empathy that in turn predict specific Dark Triad traits. Results are discussed using an evolutionary paradigm.     

Different routes to limited empathy in the sexes: Examining the links between the Dark Triad and empathy

A fundamental observation regarding the Dark Triad traits (i.e., narcissism, psychopathy, and Machiavellianism) is that they are all associated with limited empathy. However, little is known about these relationships beyond some basics. In this study (N = 352), we asked three questions. What is the nature of the relationship between the Dark Triad traits and empathy? Does limited empathy account for sex differences in the Dark Triad? Are men and women low on empathy through different personality traits? The Dark Triad traits were all related to low levels of empathy even when controlling for the shared variance among the traits. Empathy rates mediated sex differences in different aspects of the Dark Triad but not others. Low empathy rates were related to narcissism in women but psychopathy in men, suggesting different routes to limited empathy for men and women high on the Dark Triad.     

Mate-selection and the Dark Triad: Facilitating a short-term mating strategy and creating a volatile environment

The current study (N = 242) seeks to establish the relationship between traits known collectively as the Dark Triad - narcissism, psychopathy, Machiavellianism - and mating standards and preferences. Using a budget-allocation task, we correlated scores on the Dark Triad traits with mate preferences for a long-term and short-term mate. Men scoring high on the Dark Triad may be more indiscriminate than most when selecting for short-term mates in order to widen their prospects. Furthermore, those high on the Dark Triad - psychopathy in particular - tend to select for mates based on self-interest, assortative mating, or a predilection for volatile environments. We assessed these correlations when controlling for the Big Five and the sex of the participant. We also tested for moderation by the sex of the participant and mating context. Ramifications and future directions are considered.     

Pathology,pseudopathology, and the Dark Triad of personality

The Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) have traditionally been viewed as undesirable and pathological. In contrast, an evolutionary perspective suggests that traits like these might be pseudopathologies; traits that society actively dislikes in that they pose a threat to the collective good. We examined (N = 290) how the Dark Triad traits related to intrapersonal (i.e., behavioral dysfunction), quasibehavioral (i.e., reactive and proactive aggression), and interpersonal (i.e., communal and exchange orientation) factors. Psychopathy predicted high rates of behavioral dysregulation and both forms of aggression. Psychopathy and Machiavellianism showed an aversion towards communalism but an exchange orientation to social relationships. Lastly, individual differences in the Dark Triad traits accounted for part (5–22%) of the sex differences in social strategies and aggression. The theoretical implications of these findings are discussed in, and in support of, an evolutionary paradigm.     

The young and the restless: Examining the relationships between age,emerging adulthood variables,and the Dark Triad

The Dark Triad is a set of correlated personality variables (i.e., narcissism, psychopathy, and Machiavellianism) that are related to myriad behaviors. Myriad studies have been conducted to test the relations between the Dark Triad and other personality variables (e.g., the Big 5); however, the developmental correlates have been understudied. In the current study, we examined how markers of emerging adulthood and age predict the Dark Triad traits using a cross-sectional design. Participants (N = 442) of varying ages (M age = 32.99, range = 18–74) completed Dark Triad measures and a validated questionnaire used to assess the degree to which participants believe they have successfully navigated through various facets of emerging adulthood. Emerging adulthood facets (e.g., negativity, other-focused, and feeling in-between) correlated with several Dark Triad traits. Additionally, several emerging adulthood facets mediated the relation between age and the Dark Triad traits; i.e., older participants were lower on the Dark Triad traits because of the successful transition through emerging adulthood. Results are discussed in terms of the Theory of Emerging Adulthood (Arnett, 2000).     

Walking the thin line between efficiency and accuracy: Validity and structural properties of the Dirty Dozen

In this study (N = 210), participants were sampled through the Mechanical Turk system to assess the validity and structural properties of the Dark Triad Dirty Dozen (i.e., narcissism, psychopathy, and Machiavellianism). First, the correlations of the Dirty Dozen and long-form Dark Triad measures with sociosexual behaviors, attitudes, and desires, were generally consistent. Second, the scales of the Dirty Dozen measure modestly correlated with other measures of the same constructs as would be expected given the reduction in content-breadth. Third, the scales tap different dimensions (e.g., primary psychopathy, entitlement) of the older measures despite the loss of content. Fourth, a series of factor analyses revealed that the three dimensional structure replicates, but the data were best explained by a bifactor model. Despite traditional objections to short measures, if the short measure is up to the task of measuring its constructs and has good structural properties, it is a useful tool. Whereas the Dirty Dozen appears to provide conservative estimates of correlations it does appear to be a valid and psychometrically sound measure of the Dark Triad.     

The Dark Triad and risk behavior

The Dark Triad traits—Machiavellianism, narcissism, and psychopathy—are theorized to facilitate short-term, exploitative social tactics. Thus, the Dark Triad traits should be positively related to (a) similar short-term-focused traits such as impulsivity and sensation-seeking, and (b) risky behaviors. In two studies (N > 1400), we examined the relationships among the Dark Triad traits and impulsivity and sensation-seeking. In Study 2, we incorporated risk behaviors, including blackjack betting and temporal discounting of money. Both studies showed positive relationships among the Dark Triad traits and impulsivity and sensation-seeking. Study 2 showed positive relationships among the Dark Triad traits, blackjack betting, and steeper temporal discounting. An experimentally manipulated ego threat in Study 2 marginally moderated the narcissism–discounting relationship; ego-threatened participants had a significantly positive relationship, whereas those who were not threatened showed no relationship. We discuss implications of the Dark Triad traits for understanding risk behavior.     

Positioning the Dark Triad in the interpersonal circumplex: The friendly-dominant narcissist,hostile-submissive Machiavellian,and hostile-dominant psychopath?

People scoring high on the Dark Triad traits narcissism, Machiavellianism, and psychopathy are believed to get ahead without getting along. The current work positions the Dark Triad into the interpersonal circumplex around Agency/Communion. Two studies (Ns = 184, 186) with self- and peer-ratings indicated that narcissism was inclined towards friendly-dominant, Machiavellianism towards hostile-submissive, and psychopathy towards hostile-dominant when using multiple regressions. The unique location of each Dark Triad member in the interpersonal circumplex is discussed.     

Competition,autonomy, and prestige: Mechanisms through which the Dark Triad predict job satisfaction

Organizational researchers increasingly recognize the need to consider the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) when explaining undesirable work outcomes (e.g., counterproductive behaviors). However, little research has focused on the motivations of those who actually hold the traits. In this study (N = 361) we examined how the Dark Triad traits predispose individuals to perceive situations as competitive, prestigious, and comprised of restrictions (i.e., autonomy) which differentially predict job satisfaction. Individuals high on psychopathy and Machiavellianism perceived their workplaces as competitive, whereas individuals high on narcissism perceived their workplaces as prestigious and with fewer restrictions. Sex differences in perceptions were fully mediated by psychopathy and Machiavellianism. We discuss our results from an Evolutionary Industrial/Organization Psychology framework.     

Dominance styles mediate sex differences in Dark Triad traits

We sought to determine what styles of social dominance are associated with Dark Triad traits (i.e., narcissism, psychopathy, and Machiavellianism) and whether sex differences in Dark Triad traits are mediated by dominance styles measured by the Dominance and Prestige Scale, and the Rank Styles with Peers Questionnaire. Machiavellianism, psychopathy, and narcissism are strongly associated with dominance-striving, but only narcissism is consistently correlated with prestige-striving. Dark Triad traits are negatively correlated with coalition-building, but positively correlated with dominant leadership and ruthless self-advancement. Sex differences in Dark Triad traits were mediated by various dominance styles, but mainly by dominance-striving and ruthless self-advancement. These results suggest that particular styles of social dominance are utilized by both men and women with Dark Triad traits.     

Acquisitive or protective self-presentation of dark personalities? Associations among the Dark Triad and self-monitoring

The Dark Triad (narcissism, Machiavellianism, psychopathy) is associated with interpersonal manipulation which requires skills in navigating through social situations. Thus, positive relationships between the Dark Triad and self-monitoring (acquisitive: perceptiveness, impression management; protective: protective variability, protective social referencing) were hypothesized and examined in an online-study (N = 408) with (canonical) correlations and factor analyses. Results indicated that narcissism was related especially to acquisitive, Machiavellianism to protective, and psychopathy to both forms of self-monitoring, which supports the view of distinct Dark Triad traits. Findings are discussed concerning different aspects of self-presentation.     

Putting the “IRT” in “Dirty”: Item response theory analyses of the Dark Triad Dirty Dozen—An efficient measure of narcissism,psychopathy, and Machiavellianism

The Dark Triad Dirty Dozen is a new, concise personality inventory designed to measure individual differences in narcissism, psychopathy, and Machiavellianism in sub-clinical populations. To date, the psychometric work on this measure has used classical test theory to assess its validity, reliability, and structure. In two independent samples (N = 1014), we provide the first analyses of this measure using item response theory. In both samples, the Dark Triad Dirty Dozen efficiently recovered information and showed some evidence of differential scale functioning by sex, with a lower endorsement threshold for men compared to women. Results shed new light on the measurement of these “dark” personality traits.     

The role of impulsivity in the Dark Triad of personality

Among the Dark Triad of personality, both narcissism and psychopathy have been linked to impulsivity. What remains unclear is the pattern of associations that the Dark Triad have with functional and dysfunctional types of impulsivity. Using both student (N = 142) and adult samples (N = 329), we investigated the association of the Dark Triad variables with Dickman’s measures of functional and dysfunctional impulsivity. Based on regression analyses, psychopathy was most closely associated with dysfunctional impulsivity whereas narcissism was associated with functional impulsivity. It appears that narcissistic impulsivity involves venturesome social engagement whereas psychopathic impulsivity stems from poor self-regulation. As expected, Machiavellianism had no consistent association with either type of impulsivity. In short, the Dark Triad members show a coherent pattern of relations with impulsivity.     

Hedonism,Achievement, and Power: Universal values that characterize the Dark Triad

Using a sample of Swedes and Americans (N = 385), we attempted to understand the Dark Triad traits (i.e., Machiavellianism, narcissism, and psychopathy) in terms of universal social values. The Dark Triad traits correlated significantly with all 10 value types, forming a sinusoid pattern corresponding to the value model circumplex. In regression analyses, Machiavellianism and narcissism were positively associated with the values Achievement and Power, while psychopathy was positively associated with the values Hedonism, and Power. In addition, the Dark Triad traits explained significant variance over the Big Five traits in accounting for individual differences in social values. Differences between the Swedish and the US sample in the social value Achievement was mediated by the Dark Triad traits, as well as age. Given the unique complex of values accounted for by the Dark Triad traits compared to the Big Five traits, we argue that the former account for a system of self-enhancing “dark values”, often hidden but constantly contributing in evaluations of others.     

Valuing myself over others: The Dark Triad traits and moral and social values

In samples from America and Germany (N = 1353), we examined how the Dark Triad traits related to different value systems as measured by Moral Foundations and Social Values. Psychopathy was linked to diminished concerns for all Moral Foundations, Machiavellianism was linked to a moral flexibility, and narcissism was linked to a socially desirable form of morality. Machiavellianism and psychopathy scores were associated with a devaluing of collective interests, whereas narcissism was associated with a valuing of individual interests through the value of Self-Enhancement. Individual differences in a variety of values mediated part of the sex differences in the Dark Triad traits. We contend that what makes the Dark Triad traits unique and interesting is that they share a unique complex of values that might run counter to societal expectations for selflessness.     

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.

The relation between antisocial personality and the perceived ability to deceive

The current study investigated relations between the perceived ability to deceive and the Dark Triad personality traits in two samples. In study 1, the sample consisted of 1074 participants (329 male, 745 female) aged 17–71 years (M = 22.96, SD = 6.92). Participants completed the perceived ability to deceive scale, in which they were asked to estimate the percentage of people who are worse at lying than they are in a number of situations. Participants also completed the Short-D3 – a measure of the Dark Triad personality traits. As expected, correlational analyses demonstrated that Machiavellianism was most highly correlated with the perceived ability to deceive (r = .41), followed by psychopathy (r = .35), and narcissism (r = .33). These findings were replicated in study 2, which consisted of 1448 undergraduate students (498 males, 947 females, 3 other), aged 18–43 (M = 18.35, SD = 1.77). Study 2 also investigated the association of the Dark Triad and perceived ability to deceive with dimensions of the Big Five model of personality. Implications are discussed.     

Feeling me,feeling you? Links between the Dark Triad and internal body awareness

Despite a rapid increase of interest in the Dark Triad of personality (i.e., psychopathy, narcissism and Machiavellianism), very little research has focused on links between the Dark Triad and internal body awareness (i.e., interoception). In an on-line study (N = 323), we investigated the relationship between the Dark Triad and different facets of interoception, such as awareness and trust in body sensations, the capacity to regulate attention, and an awareness of mind–body integration. When we controlled for shared variance between the Dark Triad traits, narcissism emerged as a positive predictor for all but one facet of interoception. Primary psychopathy was a positive predictor of attention regulation, whereas secondary psychopathy was a negative predictor of awareness of body sensation and attention regulation. Machiavellianism emerged as a negative predictor of trusting body sensations. The findings are discussed within an evolutionary framework.
