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.     

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.     

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.     

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.     

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 perceived attractiveness and traits of the Dark Triad: Narcissists are perceived as hot,Machiavellians and psychopaths not

The current work investigated how a fictitious opposite-sex narcissist, Machiavellian, and psychopath are perceived in an experimental between subjects-design with three groups (total N = 184). Participants rated personality traits (Big Five and Agency/Communion) and different domains of interpersonal attraction (likeability, attractiveness, friend value, short-term mate value, long-term mate value) of the target persons. While all three target persons were not perceived particularly favorably by participants, the narcissist was consistently perceived more favorably than the Machiavellian and the psychopath who were perceived quite similarly to each other. It is discussed why narcissists may be judged more favorably and Machiavellians and psychopaths converge in people’s lay perceptions.     

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.     

The dark side of Facebook: Semantic representations of status updates predict the Dark Triad of personality

Using Latent Semantic Analysis, we quantified the semantic representations of Facebook status updates of 304 individuals in order to predict self-reported personality. We focused on, besides Neuroticism and Extraversion, the Dark Triad of personality: Psychopathy, Narcissism, and Machiavellianism. The semantic content of Facebook updates predicted Psychopathy and Narcissism. These updates had a more “odd” and negatively valanced content. Furthermore, Neuroticism, number of Facebook friends, and frequency of status updates were predictable from the status updates. Given that Facebook allows individuals to have major control in how they present themselves and draw benefits from these interactions, we conclude that the Dark Triad, involving socially malevolent behavior such as self-promotion, emotional coldness, duplicity, and aggressiveness, is manifested in Facebook status updates.     

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.     

Facing a psychopath: Detecting the dark triad from emotionally-neutral faces, using prototypes from the Personality Faceaurus

Is facial structure a valid cue of the dark triad of personality (Machiavellianism, narcissism, and psychopathy)? I obtained self-reports and peer reports of personality as well as expression-neutral photographs of targets, and then I created prototypes of people high and low on each of the three dimensions by digitally combining select photographs of Caucasian targets. The results indicated that unacquainted observers reliably detected the dark triad composite, especially in female prototypes. Thus, not only is the dark triad a set of psycho-social characteristics—it may also be a set of physical–morphological characteristics. In the Discussion, I introduce a website that stores these personality prototypes and many others (http://www.nickholtzman.com/faceaurus.htm).     

Relationships between Machiavellianism, emotional intelligence and theory of mind in children

The current study investigates the associations of Machiavellianism (Mach) with trait and ability emotional intelligence (EI), and theory of mind (ToM) in 109 primary school children. Consistent with previous research with adults, negative associations were found between Mach and social and emotional understanding. Subsequent multiple regression analyses for girls showed that being more adept at emotional and social understanding does not lead them to manipulate others in social encounters. This was not the case for boys. These findings are discussed in relation to other social and individual difference variables that impact on Mach, particularly amongst boys.     

Psychopathic personality traits and cognitive dissonance: Individual differences in attitude change

In a study using a classic cognitive dissonance paradigm, 164 undergraduate participants were induced to deceive a fellow student; half were directly instructed to lie whereas the other half were politely requested but not instructed to lie. Participants were assessed for psychopathic traits using the Psychopathic Personality Inventory-Revised: Short Form and the Levenson Self-Report Psychopathy Scale, and for Machiavellianism using the MACH-IV. As predicted, participants low in psychopathic traits exhibited classic cognitive dissonance effects following their lie whereas participants high in psychopathic traits did not. Results for Machiavellianism were nonsignificant. These results indicate that cognitive dissonance effects in an induced compliance paradigm are reduced or eliminated among individuals with high levels of psychopathic traits.     

Hermeneutics and theory of mind

In contemporary philosophy and psychology there is an ongoing debate around the concept of theory of mind. Theory of mind concerns our ability to understand another person. The two approaches that dominate the debate are “Theory Theory” (TT) and “Simulation Theory” (ST). This paper explores the connection between theory of mind and hermeneutics. Although both speak of the nature of understanding, and the way we gain and organize our knowledge of others, certain aspects of Schleiermacher’s hermeneutics reflect a theory approach, long before TT itself was developed. In contrast, Dilthey’s hermeneutics reflects a simulation approach. In contrast to both of these approaches, I propose a contextual theory, as a parallel to Gadamer’s work in hermeneutics, and as a view that offers the basis for an important critique of both TT and ST.

Teaching children to understand metaphors as a path leading to theory of mind development

The objective of the present study was to verify whether metaphors could be a tool in examining and teaching children's theory of mind (ToM) ability. Searching for sources of ToM development, we tried to stimulate mind-reading ability via metaphors. A group of 109 children participated in the project. Four and five-year-old participants (mean age 4 years, 11 months) were randomly divided into three groups: two experimental groups (with two kinds of prompts: direct, linguistic and indirect, contextual) and the controls. All the participating children were to solve three false beliefs and one metaphors test (with or without prompts). The results show that metaphors may provide an ecologically relevant and reliable tool for testing ToM in children. Although the methods employed to teach metaphors understanding proved ineffective, a critical analysis of the results provides important suggestions for further research.     

A longitudinal study of child siblings and theory of mind development

This study tested a sample of 63 children twice in a longitudinal design over 14 months to examine their theory-of-mind (ToM) understanding in relation to their number of child-aged siblings (1–12 years). Age-appropriate batteries of ToM tests emphasising false belief were given at the start of the study, when children had a mean age of 4–2 (range: 3–3 to 5–6), and at the end, when mean age was 5–4 (range: 4–3 to 6–9). Irrespective of chronological age, children with 2 or more child siblings scored significantly higher on both the earlier and the later battery than those with no child-aged siblings. Hierarchical multiple regression analyses revealed that, over and above chronological age and verbal intelligence, having more child siblings predicted higher ToM scores at Times 1 and 2. Furthermore, at Time 2, the participant's number of child-aged siblings continued to predict higher ToM scores even after controlling for age, verbal intelligence, and Time 1 ToM scores. Results were considered in relation to the kinds of family-based social and conversational experiences that might foster ToM growth throughout the period from toddlerhood to the threshold of primary school.     

The accidental transgressor: morally-relevant theory of mind

To test young children’s false belief theory of mind in a morally relevant context, two experiments were conducted. In Experiment 1, children (N = 162) at 3.5, 5.5, and 7.5 years of age were administered three tasks: prototypic moral transgression task, false belief theory of mind task (ToM), and an “accidental transgressor” task, which measured a morally-relevant false belief theory of mind (MoToM). Children who did not pass false belief ToM were more likely to attribute negative intentions to an accidental transgressor than children who passed false belief ToM, and to use moral reasons when blaming the accidental transgressor. In Experiment 2, children (N = 46) who did not pass false belief ToM viewed it as more acceptable to punish the accidental transgressor than did participants who passed false belief ToM. Findings are discussed in light of research on the emergence of moral judgment and theory of mind.
