Approach/avoidance tendencies in dark personalities

Dark triads, tetrads, tents, and cores: Why navigate (research) the jungle of dark personality models without a compass (criterion)?

This comprehensive review summarizes and evaluates the present state of the Dark Triad research literature (or more broadly, the dark personality trait literature), and as such serves both a pedagogical purpose, by providing an introduction or primer on the dark personality literature and a scientific purpose by directing future research on key issues that still have not been sufficiently addressed. In this review, we discuss and critique current operational conceptualizations of what it means for a personality trait to be classified as 'dark'. Also discussed is the Dark Core, as well as quantitative issues such as limitations of commonly used statistical treatments, such as multivariate analyses, bifactor modeling, and composite measures, and proposed solutions to some of these issues. Based on a comprehensive and critical appraisal of the literature, future directions are suggested to drive the dark trait field towards a more organized, parsimonious, and productive future.

Thanks, but No Thanks: Unpacking the Relationship Between Relative Power and Gratitude

Power and gratitude are universal features of social life and impact a wide range of intra- and interpersonal outcomes. Drawing on the social distance theory of power, we report four studies that examine how relative power influences feelings and expressions of gratitude. An archival analysis of author acknowledgements in published academic articles (N = 1,272) revealed that low-power authors expressed more gratitude than high-power authors. A pre-registered experiment (N = 283) involving live conversations online found that having relatively low power caused increased feelings and expressions of gratitude after benefiting from a favor. Another pre-registered experiment (N = 356) demonstrated that increased interpersonal orientation among lower power individuals and increased psychological entitlement among higher power individuals drove these effects. Finally, an archival analysis of conversational exchanges (N = 136,215) among Wikipedia editors revealed that relational history moderated the effect of relative power on gratitude expression. Overall, our findings highlight when and why relative power influences feelings and expressions of gratitude.

Unhealthy parenting strategies: Situational (Dis-)Incentives, Machiavellian personality, and their interaction on misuse of ADHD medication for healthy children

Some parents engage in the potentially unhealthy and morally debateable parenting practice of giving prescription stimulant drugs to healthy children to boost their school and extracurricular performance. However, the parents' underlying reasoning remains unexamined. This web-based study (N_Respondents = 1360) simultaneously investigates eight experimentally-varied situational (dis-)incentives (e.g., financial gains and drug properties) within a factorial vignette survey (N_Vignettes = 256), Machiavellianism as a measured socially relevant personality trait, and possible interaction effects. Results show that approximately 40% of the described situations (N_Evaluations = 5440) provoked some willingness to medicate healthy children. Multilevel mixed-effect models revealed that this willingness was higher, for example, with increasing financial gains and weaker side effects. Machiavellians disclosed a higher willingness. They were more responsive to financial gains and threats (e.g., probable side effects). Respondents' sex, age, ethnicity, and experience with prescription drugs also had effects. Prevention measures might emphasize the dangers and limited potential of prescription drugs for healthy children.

The Dark Triad and BIS/BAS: a Meta-Analysis

Are there any temperamental predispositions to developing a dark personality traits? Within the current paper we address this question by investigating relations between the temperamental traits of the behavioural inhibition and approach systems (BIS and BAS, respectively) and the Dark Triad traits of personality. For this purpose, we conducted a meta-analysis of 18 studies with a total of 8911 participants. The results partially corroborated existing claims that the Dark Triad traits are a group of high-approach low-avoidance temperamental traits; however, the role of BAS seems to be more important. Among the Dark Triad traits, narcissism seems to be the most related to both the BIS and the BAS. Psychopathy in turn seems to be mostly related to the fun-seeking facet of the BAS. Finally, Machiavellianism appears to be the least related to temperamental traits. Thus, it seems that only narcissism and psychopathy confirm the claim about a connection between the Dark Triad traits and a high-approach low-avoidance temperament.

Perceptions of Close Relationship Through the Machiavellians´ Dark Glasses: Negativity, Distrust, Self-Protection Against Risk and Dissatisfaction

It is commonly known from the literature that Machiavellian individuals have negative attitudes towards people and in general towards the world´s affairs. They are distrustful of the intentions of others, and they get cautiously involved into interpersonal interactions and take risks only if that may not have any severe negative consequence. It is also a fact that there are few ventures in life that potentially involve as much insecurity and personal vulnerability as the establishment and maintenance of close relationships. In our study, we were seeking the answer to the question: do people with high levels of Machiavellianism show a generally negative, distrustful and cautious attitude in their intimate relationships, as well? What effect their pessimistic approaches have on the other consequences of the relationship (satisfaction, commitment, investment, quality of alternatives)? This question was investigated on a dyadic sample of heterosexual couples (N = 101 pairs) with Actor-Partner Interdependence Model (APIM). The results of the correlations and actor effects show that men with high levels of Machiavellianism perceive in a negative way not just people in general, but their romantic partners and relationships as well and they experience an increased level of distrust, risk, and dissatisfaction into their close relationships. Women with high levels of Machiavellianism are less negativistic and feel less discontent towards their intimate partner and relationship, but even they are unable to put their distrust and precaution aside. The results of partner effects have revealed that women's Machiavellianism undermines men's trust, while men's Machiavellianism has the effect of minimizing women's investment into their relationship.

Structural Relationships Among the Revised Reinforcement Sensitivity Theory and Grandiose and Vulnerable Narcissism

Research shows that grandiosity and vulnerability are distinct aspects of narcissism. The Contemporary Clinical Model (CCM) of narcissism suggests that individuals fluctuate between grandiose narcissism (GN) and vulnerable narcissism (VN). The authors examine the relative contributions of the Behavioral Approach System (BAS), the Behavioral Inhibition System (BIS), and the Fight-Flight-Freeze System (FFFS) in the Revised Reinforcement Sensitivity Theory of Personality (r-RST) to GN and VN. Few studies examine the r-RST, and even fewer examine the VN and GN distinction. To remain consistent with the CCM, structural equation modeling was used to account for individuals' relative levels of VN and GN. Across two independent samples (Ns = 854 and 258), results indicated that GN is associated with higher BAS scores and that VN is associated with higher BIS scores. Relations among GN, VN, and FFFS were inconsistent between samples. Implications of the r-RST results are interpreted within the context of the CCM.

Dark malevolent traits and everyday perceived stress

Stress is a factor that greatly impacts our lives. Previous research has examined individual differences in relation to stress. However, research regarding malevolent personality traits in relation to how stress is perceived is limited. The purpose of the present study was to investigate relationships between dark malevolent personality traits; psychopathy (EPA), Machiavellianism (MACH-IV), vulnerable narcissism (HSNS), grandiose narcissism (NPI-13), and perceived stress (PSS-10) in a community sample (N = 346). The results showed a strong positive relationship between vulnerable narcissism and perceived stress, while grandiose narcissism and psychopathy showed a small negative relationship with perceived stress. The discussion centers on that narcissism should be treated as two separate traits, and that psychopathy and Machiavellianism overlap in relation to the experience of stress in everyday life.

Machiavellian tendencies increase following damage to the left dorsolateral prefrontal cortex

Machiavellianism - a personality trait that is characterized by a tendency to distrust, deceive and exploit others - has been the focus of growing attention in psychological research. Neuroimaging studies of Machiavellianism highlight the influence of the dorsolateral prefrontal cortex (dlPFC) on Machiavellianism tendencies. However, knowledge regarding the causal role of the left and right dlPFC on Machiavellianism is still obscure. Here, we measured general Machiavellian tendencies, as well as two subscales (i.e., Machiavellian Views and Machiavellian Tactics) in a large sample of brain-injured patients (N = 129) and non-brain-injured control participants (N = 37) to determine whether Machiavellianism tendencies can be altered by brain damage. We analyzed Machiavellianism tendencies as a function of lesion location, with patients separated into four groups based on dlPFC damage: left dlPFC damage, right dlPFC damage, non-dlPFC damage, and healthy controls. We found that left dlPFC damage increased Machiavellianism in general, and Machiavellian perspective (views) in particular, but did not modulate behavior (tactics). Critically, left dlPFC damage predicted higher levels of Machiavellianism after controlling for general and emotional intelligence, linguistic abilities, empathy and psychopathology. These findings establish a causal role of the left dlPFC in modulating Machiavellian views, and indicate that one can hold Machiavellian views without necessarily endorsing Machiavellian tactics.
