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.     

Testing Measurement Invariance of the Dark Triad Dirty Dozen in a Belgian Adult Sample

The Dirty Dozen (Jonason & Webster, 2010) is a frequently used concise version of the Dark Triad to measure three socially aversive personality traits: Machiavellianism, psychopathy and, narcissism. The present study has examined measurement invariance in a sample of Belgian adults. The present study aims to assess measurement invariance of the Dutch version of the Dirty Dozen measure across gender in a large city-based representative adult sample in Belgium (N = 1587). Multi-group first-order confirmatory factor analysis for categorical indicators was utilized. In addition, unique associations between Dirty Dozen traits, trait self-control and, acceptance of illegitimate norms were examined in a series of structural equation models. Results indicated that the internal consistency of the Dirty Dozen subscales was good for Machiavellianism (α = 0.80) and narcissism (α = 0.80), but modest for psychopathy (α = 0.64). The hypothesized three correlated factors model with separate factors for Machiavellianism, psychopathy and, narcissism provided a poor fit for men and women. Invariance testing across gender showed evidence for weak invariance only, indicating that the underlying latent factors are measured the same way with the same metric in the two populations. However, we were not able to establish strong measurement invariance. Observed group differences should be interpreted with caution. Furthermore, Machiavellianism and psychopathy were strongly associated with trait self-control in both men and women. Strong correlations were found between acceptance of illegitimate norms and Dirty Dozen traits, Machiavellianism and, psychopathy, but not with narcissism.     

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.     

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.     

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.     

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.     

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.     

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.     

Dark triad and impulsivity – an ecological momentary assessment approach

Previous studies have shown that the Dark Triad traits (psychopathy, narcissism and Machiavellianism) are associated with impulsivity. However, prior work has relied exclusively on retrospective assessment via self-report questionnaires or on one-time behavioral measures of impulsive behavior. Therefore, we examined how the Dark Triad traits relate to moment-to-moment impulsivity as people navigate through their natural environment in a given day. For 14 days, 283 non-clinical adult volunteers carried smartphone devices to monitor their daily impulsive behaviors. Participants were randomly prompted five times per day. In addition, the pattern of correspondence between the moment-to-moment impulsivity monitoring and the already established impulsivity assessment methods (retrospective self-report questionnaire, i.e., 48-item Discounting Inventory; behavioral task, i.e., Delay-Discounting task with pairs of hypothetical choices) was tested. Strong correlations were found between psychopathy, narcissism, and self-reported impulsivity. Moreover, those traits showed weaker (but still significant) correlations with both, the one-time behavioral and the momentary monitoring measures of impulsivity. Machiavellianism did not correlate with any type of impulsivity assessment. When testing the association between the self-report, behavioral, and momentary measures of impulsivity, analysis revealed weak to moderate correlations. Reliably, these results support other recent findings suggesting that those three impulsivity tasks probably measure different constructs.

     

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.     

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).     

Birds of a “bad” feather flock together: The Dark Triad and mate choice

Previous research on the Dark Triad traits (i.e., Machiavellianism, psychopathy, and narcissism) has focused solely on the role the Dark Triad traits played in mate choice of actors. The current study (N = 336) extends this by manipulating the apparent levels of Dark Triad traits in targets and correlating mate choice in these targets with individual differences in the Dark Triad traits in actors. As expected, both sexes preferred partners low in the Dark Triad traits for long-term mating, while those high in these traits were preferred for one-night stands. However, women high in psychopathy considered the Dark Triad traits in potential male partners more physically attractive and desirable for an one-night stand, as well as a potential husband. Men who were high on psychopathy were likewise attracted to psychopathy in potential mothers. Our findings are discussed from an evolutionary personality paradigm.     

Personality,the Dark Triad and violence

Aggression involves using force to dominate a situation, whereas violence uses force to do intentional harm. Previous research suggests the Dark Triad underlies much anti-social behaviour, and is associated with aggression. We extend this work to examine whether Dark Triad constructs predict self-reported violence. The Dark Triad, measured using the SD3, was examined in relation to normal personality traits as indexed by the HEXACO, which comprises a general Big Five structure with the addition of an Honest–Humility dimension. We also measured impulsivity using the I-7. A sample of 159 adults completed the measures. Principal Components Analysis revealed Machiavellianism, psychopathy and violence loaded on the same factor, which also had negative loadings for HEXACO domains of Honesty–Humility and Agreeableness. Narcissism loaded on a separate factor which was also defined by Extraversion. Hierarchical regression analyses found Agreeableness a more powerful predictor of violence than psychopathy or Machiavellianism, both of which showed a trend to this association; narcissism had no effect. Agreeableness emerged as the strongest negative predictor of violence, and exclusively explained the majority of variance in violence scores. Findings are discussed regarding the centrality of low agreeableness as a driving force behind the Dark Triad and the constructs it predicts.     

The Dark Triad Traits,Humor Styles,and Schadenfreude: Others' Misery as the Devil's Laughing Stocks1

This research investigated the relationships of the Dark Triad traits, humor styles, and schadenfreude with 169 participants who completed the Short Dark Triad, the Humor Style Questionnaire, and a measure of schadenfreude. Significant correlations imply that those with salient dark traits (psychopathy, Machiavellianism, narcissism) elicit pleasure from others' misfortune. Additionally, schadenfreude can be a product of self-defeating and aggressive humor styles. Indirect effect analysis revealed the significance of the indirect effect of the measured aggressive humor style on the Dark Triad's direct effects on schadenfreude. These results imply that those with salient Dark Triad traits enjoy others' misery as a means to undermine them. Hence, individuals with salient Dark Triad traits tend to engage in downward social comparison.     

Assortative mating for Dark Triad: Evidence of positive,initial, and active assortment

Hypotheses regarding positive versus negative assortment, initial assortment versus convergence, and active assortment versus social homogamy were tested on a sample of 100 heterosexual dating couples using variable‐ and couple‐centered approaches. A modest to moderate degree of positive assortment was found for all Dark Triad measures, the highest for Machiavellianism, followed by psychopathy and narcissism. Structural modeling also showed a moderate degree of positive assortment for men's and women's latent Dark Triad constructs. Results supported the initial assortment hypothesis, meaning that couples were already similar in the Dark Triad traits at the beginning of the relationship and did not converge over time. Additionally, similarity was not due to background variables such as age and education (i.e., social homogamy), thus supporting the active assortment hypothesis.     

The Dark Triad at work: How toxic employees get their way

Toxic employees have come under serious investigation lately. In this study (N = 419) we examined the role the Dark Triad traits, as measures of being a toxic employee, play in predicting tactics of workplace manipulation and how the Dark Triad might mediate sex differences in the adoption of hard (e.g., threats) and soft tactics (e.g., offering compliments). Psychopathy and Machiavellianism were correlated with adopting hard tactics whereas Machiavellianism and narcissism were correlated with adopting soft tactics. The Dark Triad composite fully mediated the sex differences in the adoption of hard tactics but not soft tactics. The Dark Triad may facilitate the adoption of numerous tactics of influence independently but collectively may lead men more than women to adopt an aggressive or forceful style of interpersonal influence at the workplace.     

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.

Creativity and the Dark Triad: A meta-analysis

This paper presents a meta-analysis of the relationships between creativity (creative potential, activities, and achievement) and the Dark Triad of personality: narcissism, Machiavellianism, and psychopathy. Multilevel meta-analytic models demonstrated a small but significant positive association between creativity and narcissism (r = 0.15 [0.10, 0.29]) and Machiavellianism (r = 0.06 [0.02, 0.09]), but not with psychopathy (r = 0.03 [-0.02, 0.07]). Creativity measures (self-report-vs.-performance), aspects (self-perception, creative activity, creative abilities, creative achievements), and domains (general, art, science, and everyday creativity) moderated the links with the Dark Triad. We discuss the possible mechanism of associations between Dark Triad traits and creativity and highlight future research directions.
