Understanding dark side personality at work: Distinguishing and reviewing nonlinear,interactive, differential,and reciprocal effects

The topic of dark side personality at work has received considerable research attention over the past decade, and both qualitative and quantitative reviews of this field have already been published. To show the relevance of dark personality in the work context, existing reviews have typically focused on systematically discussing the different criteria that have been linked to dark traits (e.g., job performance, work attitudes, leadership emergence, etc.). In contrast, and complementing this earlier work, the current review paper summarizes the available literature on this topic by structuring it in terms of the nature of the relationships studied rather than in terms of the types of outcome variables. Doing so, the focus shifts from “What are the outcomes of dark traits?” to “How are dark traits related to work outcomes?” Scrutinizing the nature of these relationships, we specifically focus on four types of effects (i.e., nonlinear, interactive, differential, and reciprocal) that highlight the complexity of how dark side traits operate in the work context. Structured this way, this review first provides a conceptual underpinning of each of these complex effects, followed by a summary of the empirical literature published over the past 10 years. To conclude, we present an integration of this field, provide suggestions for future research, and highlight concrete assessment challenges.     

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).     

The Dark Triad,happiness and subjective well-being

Narcissism can be expressed in grandiose or vulnerable forms. We examined whether positive psychological states (defined by the Oxford Happiness Inventory (OHI) and the Diener Satisfaction With Life (SWL) scales) assisted differentiation relative to general personality traits and the “the Dark Triad” (psychopathy, narcissism, and Machiavellianism, measured by the D12 and Short Dark Triad (SD3) indices) for 840 persons primarily from the UK, USA and Canada. The best fitting structural equation model comprised two latent variables, one of positive mood (comprising total scores on the OHI and SWL scales), and another forming a “dark dyad” of Machiavellianism and psychopathy (predicted by low agreeableness and lower positive mood), with narcissism regarded as a separate construct correlated with the dark dyad. Latent positive mood was primarily predicted by higher emotional stability and extraversion. Narcissism was predicted by lower emotional stability, lower agreeableness, and higher extraversion. Latent profile analysis identified four groups in the data: “unhappy but not narcissistic”, “vulnerable narcissism”, “happy non-narcissism” and “grandiose narcissism”. Our results suggest more problematic narcissism can be identified by reference to measures indexing positive mood states and general personality traits.     

Moral disengagement,the dark triad,and unethical consumer attitudes

PurposeBandura’s theory of moral disengagement explains how otherwise ethical persons can behave immorally. We examined whether a trait model of general personality and the “dark triad” underlay moral disengagement, the relationship these constructs have to unethical consumer attitudes, and whether moral disengagement provided incremental validity in the prediction of antisocial behaviour.MethodsSelf-report data were obtained from a community sample of 380 adults via an online survey that administered all measures.ResultsCorrelations between unethical consumer attitudes, lower Agreeableness, lower Conscientiousness, higher moral disengagement, higher psychopathy, and higher Machiavellianism were captured by a single factor. When this broad factor was examined using regression, demographic, personality and the dark triad traits all predicted moral disengagement, specific influences being age, education, Intellect, psychopathy, and Machiavellianism. A similar model examining predictors of unethical consumer attitudes again found all blocks contributed to the outcome, with specific influence provided by age, Intellect, and moral disengagement, the latter showing incremental validity as a predictor of unethical consumer attitudes.ConclusionsMoral disengagement is based on low Agreeableness, Machiavellianism and psychopathic-type traits, but provides incremental validity in predicting antisocial attitudes to a trait model alone. Narcissism is neither related to moral disengagement, nor unethical consumer attitudes.     

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.     

Dark triad personality traits and theory of mind among school-age children

This study examined the associations between four personality dimensions associated with the dark triad (callous–unemotional traits, narcissism, impulsivity, and Machiavellianism) and theory of mind (TOM) abilities among 146 middle school children. Results of hierarchical multiple regression analyses showed narcissism to be positively associated with TOM, callous–unemotional (CU) traits to be negatively associated with TOM, and impulsivity and Machiavellianism to be unrelated to TOM. No significant interactions were found between gender and any of the dimensions of personality. The putative mechanisms linking each personality dimension with understanding of mental states in others are discussed, along with directions for future research.     

A meta-analytic review of the Dark Triad–intelligence connection

We conducted a meta-analytic review of the relations between general mental ability (GMA) and the Dark Triad (DT) personality traits—Machiavellianism, narcissism, and psychopathy—to determine if individuals who display socially exploitative social qualities tend to be more intelligent or less intelligent. Across 48 independent samples, GMA showed no consistent relation with any DT trait. These effects were not sufficient to support either the “evil genius” hypothesis (highly intelligent individuals tend to display socially exploitative personality traits) or the “compensatory” hypothesis (less intelligent individuals compensate for their cognitive disadvantages by adopting manipulative behavioral tendencies). However, these relations were moderated, to some extent, by the sex and age of the participants, type of sample studied, and the measure of GMA.     

The mismeasure of morals: antisocial personality traits predict utilitarian responses to moral dilemmas

Researchers have recently argued that utilitarianism is the appropriate framework by which to evaluate moral judgment, and that individuals who endorse non-utilitarian solutions to moral dilemmas (involving active vs. passive harm) are committing an error. We report a study in which participants responded to a battery of personality assessments and a set of dilemmas that pit utilitarian and non-utilitarian options against each other. Participants who indicated greater endorsement of utilitarian solutions had higher scores on measures of Psychopathy, machiavellianism, and life meaninglessness. These results question the widely-used methods by which lay moral judgments are evaluated, as these approaches lead to the counterintuitive conclusion that those individuals who are least prone to moral errors also possess a set of psychological characteristics that many would consider prototypically immoral.     

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.
