Literature on psychology highlights four traits that shape an amoral and antisocial personality: Machiavellianism, narcissism, psychopathy and sadism. Together, these personality traits form the Dark Tetrad. In this study, the standard intertemporal utility maximization model is reassessed from the point of view of a representative economic agent endowed with the Dark Tetrad personality traits.

The approach followed in this paper consists of identifying how each of the Dark Tetrad traits might be logically associated with the dynamic utility problem, as well as exploring, in the context of the model, the implications, for consumption and utility, of admitting the presence of such traits in individuals’ personalities.

It is found that, typically, dark personalities penalize consumption growth, even when such traits are interpreted directly and positively contributing to the utility of the agent. It is also found that in economies with two or more interacting agents, the dark traits might have a mutually destructive nature.

Economics is going through a smooth revolution in the direction of becoming an eminently behavioral science. Most of the traditional economic models, based on the idea of the hyper-rational agent, are being replaced or complemented by a different view of the homo-economicus, in which, among other things, personality matters. This paper offers a novel contribution in this direction.

Following the theory of emotional events, this paper aims to use the bright triad and the dark tetrad as representations to investigate the role of positive and negative personality patterns in achieving positive and negative innovation. The study also examines the mediating role of emotional intelligence and abusive supervision and the interactive role of emotional exhaustion in understanding the relationship between positive and negative personality patterns and positive and negative innovation.

To test the hypotheses of the study model, a set of questionnaires was distributed to a sample of 500 medical officers working in different departments of public hospitals in southern Iraq. The data were analysed using the structured equation model.

The results of the current study confirm previous studies on emotional intelligence because the bright triad negatively associates with negative innovation and positively associates with positive innovation. Meanwhile, the dark tetrad positively associates with negative innovation through abusive supervision, and that emotional exhaustion reinforces the negative side and weakens the positive side of the relationships.

This study contributes to the literature by emphasising that the values represented by the bright triad have a strong readiness to show positive innovation and immunity to negative influence caused by abusive supervision. Meanwhile, the negative emotions of the dark tetrad pattern result in negative patterns because they correlate with negative innovation and the avoidance of positive behaviour, which is escalated by abusive supervision.

The role of dark side personality characteristics in the workplace has received increasing attention in the organizational sciences and from leadership researchers in particular. We provide a review of this area, mapping out the key frameworks for assessing the dark side. We pay particular attention to the roles that the dark side plays in leadership processes and career dynamics, with special attention given to destructive leadership. Further, we examine the role that stress plays in the emergence of leaders and how the dark side plays into that process. We additionally provide discussion of the possible roles that leaders can play in producing stress experiences for their followers. We finally illustrate a dynamic model of the interplay of dark leadership, social relationships, and stress in managerial derailment. Throughout, we emphasize a functionalist account of these personality characteristics, placing particular focus on the motives and emotional capabilities of the individuals under discussion.

How do dark personality traits impact workplace bullying (WB)? How can organizations mitigate it? This study aims to explore the relationship between the Dark Tetrad (DT) (narcissism, psychopathy [PY], Machiavellianism and sadism [SM]) and WB, proposing the mediation role of moral disengagement (MD) and the moderation role of emotional stability (ES).

The proposed mediated-moderation model was tested on 404 employees working in the hospitality sector in Pakistan. Data have been analyzed through regression analysis and PROCESS macros to test the study’s hypotheses.

PY, Machiavellianism and SM positively relate to WB and MD mediates this relationship. A high level of ES reduces the intensity of the mediated influence of PY, Machiavellianism and SM on WB.

Developing targeted policies and practices (e.g. personality tests to build a good psychological architecture of the firm) and reviewing processes that support the moral justification of antisocial conduct can be beneficial for limiting WB. In addition, meditation, mindfulness training and supporting trust and cooperation within organizations can increase the mitigating effect of ES and, in turn, reduce WB.

To the best of the authors’ knowledge, this is the first study that explicitly verifies a mediated-moderation model on DT-WB while proposing a further explanation (i.e. mediation of MD) and a novel solution (i.e., moderation by ES).

The purpose of this study is to identify sociodemographic factors that are predictive of the level of everyday sadism (SAD) in the business area.

A survey was conducted on 424 graduate and postgraduate students from business schools in Brazil and the USA. SAD was quantified by the assessment of sadistic personality proposed by Plouffe Saklofske and Smith (2017). The variables included age, gender, managing experience, education and nationality.

The average level of SAD was low. SAD was negatively associated with gender, age and nationality and positively associated with managing experience and education.

As individuals ascend professionally and academically, they display higher levels of everyday sadism. Depending on the context, dark personalities can cause either benefit or harm to the company's business and to society. However, the literature shows that seeking pleasure and dominance with no regard for consequences affects the business area directly or indirectly.

Very few studies have addressed everyday sadism in the business area, let alone evaluated predictive factors and discussed possible implications.

The purpose of this paper is to explore if a ringing cell phone could impact cognitive performance as well as being agitating to provoke aggressive reactions. The study investigated variables that could impact a participant’s willingness to aggress and retaliate, such as sensitivity to arousal and dark personalities (DRPs), Machiavellianism, narcissism, and subclinical psychopathy and sadism.

There were 128 participants (77 women and 51 men). The cognitive load task consisted of forming anagrams while being in a high or low provocation condition. Participants were subsequently asked how willing they would be to allow one out-group member to be harmed in favor of saving several in-group members. Three personality measures were used: two measuring DRPs and one measuring arousal sensitivity.

The authors discovered that older age and subclinical psychopathy were significant predictors for the willingness to aggress. Those in the high provocation condition retaliated the most against the experimenter, and a participant’s English ability was the only variable that predicted good performance on the cognitive task.

The results warrant further research into how personality types, aggression, and everyday, multiple arousal sources intertwine to inform personalized evidence-based interventions. Organizational and educational psychologists could also use this research to in form how offices and schools are run.

Narcissism is characterized by grandiosity, and it is included in the Dark Triad with Machiavellianism and psychopathy. Narcissism relates to many detrimental outcomes, but a growing stream of research has investigated beneficial outcomes of the Dark Triad. The authors continue this stream of research by assessing the relation of narcissism with social courage behaviors, which are prosocial actions with personal social risks. The authors propose that this relation is mediated by self-deceptive enhancement and subjective invulnerability and also test these relations while including the other Dark Triad dimensions.

The authors perform two survey studies to investigate our research questions. The first utilizes a cross-sectional approach, whereas the second utilizes a time-separated approach.

The results of this study show that narcissism has an indirect effect on social courage via both mediators, and it also produced a significant direct effect. Machiavellianism and psychopathy did not produce any reliable effects on social courage – whether direct or indirect.

The authors support that a “dark” trait relates to a “bright” outcome, but also that a bright outcome relates to a dark trait. These findings link the narcissism and social courage to novel theoretical frameworks, such as those associated with ethical decision making and self-regulation, which opens many directions for future research on both constructs.

The current article addresses two recent calls for novel research: the study of courage as well as positive outcomes of negative traits. It also adds much-needed nuance to current research on narcissism and courage.

Cyberloafing has emerged as a significant phenomenon in the modern workplace, largely driven by shifts in work dynamics. Recent discussions suggest that Dark Triad traits may play a critical role in influencing cyberloafing behaviors; however, research exploring these traits in the context of cyberloafing remains limited. The purpose of this paper is to investigate the complex relationship between the Dark Triad personality traits – psychopathy, Machiavellianism and narcissism – and cyberloafing. Additionally, this study examines four other psychological variables and two demographic factors as potential correlates of cyberloafing.

The survey sample consisted of 155 working adults from the USA who participated via Amazon’s Mechanical Turk (MTurk). All participants were required to be full-time employees (working 35 or more hours per week) and hold MTurk Master qualifications.

The findings of this study provide credible support for the research hypotheses. While not all Dark Triad traits are linked to cyberloafing, the influence of certain traits is significant enough to draw meaningful conclusions. Specifically, the results of this study showed that Machiavellianism and psychopathy were associated with both forms of cyberloafing: browsing activities and emailing activities. However, narcissism was not related to any form of cyberloafing. Additionally, pay satisfaction and social media addiction were positively related to both forms of cyberloafing, while age was negatively related.

This paper addresses several limitations, suggests avenues for future research and outlines practical implications for organizations aiming to mitigate the adverse effects of cyberloafing.

Cyberloafing – engaging in non-work-related online activities during work hours – has gained increasing attention because of its potential to disrupt productivity and organizational functioning. However, limited research has explored this important behavior in depth. Building on contemporary studies, this study investigates the underlying mechanisms and potential implications of how Dark Triad traits may either encourage or mitigate cyberloafing.

This study expands on research related to the dark side of personality traits by examining how individual dark personality affects proactive work behaviours. Specifically, the authors consider paranoia as a dark personality trait and propose that it negatively relates to perceived psychological safety and indirectly affects frontline employees' (FLEs) willingness to report customer complaints as well as their extra-role customer service. The authors also posit that empathetic leadership is a focal, contextual factor that mitigates the impact of paranoia on perceived psychological safety and, consequently, the willingness to report customer complaints and engage in extra-role customer service behaviour.

The model was tested on a sample of 252 FLEs using process macro (Hayes, 2017) and AMOS. Data were collected from FLEs working in different hospitality organisations using a time-lagged design; supervisor-rated employee extra-role customer service was also measured.

The authors found that FLEs with a paranoid personality trait had a lesser sense of psychological safety at work, which reduced their willingness to engage in proactive work behaviours. However, this negative effect was mitigated by the presence of an empathetic leader.

The results are important because research has yet to determine which actions managers should take to counter the negative effects of dark personalities in the workplace.

Based on the trait activation theory and social exchange theory, this study proposed a model of the impact of Machiavellian personality on organisational cynicism (OC) through the mediating effect of psychological contract breach (PCB) and the moderating role of leader-member exchange (LMX) quality in PCB and OC.

A three-time points survey involving 264 employees from China’s hotel industry was conducted using quantitative methods. Subsequently, a structural equation model was constructed.

The results revealed that Machiavellianism positively affects OC, and PCB plays a mediating role in this process. In addition, LMX quality can buffer the effect of the PCB on OC.

The study’s findings provide another insight into the relationship between Machiavellianism, PCB and OC. Managers must pay attention to the control of PCB and the establishment of LMX quality.

The study significantly contributes to hotel literature, as the Machiavellian personality subject has not been adequately investigated in the field to date.
