Malicious mind readers? A meta-analysis on Machiavellianism and cognitive and affective empathy

At-risk mental states and personality traits: A cluster analysis approach on a group of help-seeking young adults

INTRODUCTION

Research on the relationship between personality and psychosis onset is growing, with the goal of preventing or intervening early in patients' vulnerability. The identification of individuals with at-risk mental states has enabled the development of early intervention strategies, such as Programma 2000, a youth mental health service that was implemented in Milan (Italy).

AIMS

Focusing on the 18-25 age range-the time window with the highest incidence of psychotic onset-this study aims to identify the personality traits that may characterize the at-risk mental states and the social functioning of a group of help-seeking young adults.

METHODS

The sample includes 169 people (48.5% males and 51.5% females). Data were collected during an initial assessment that comprised the Social and Occupational Functioning Assessment Scale, the Personality Inventory for DSM-5, the Checklist ERIraos and a clinical session.

RESULTS

Results identified a three-cluster solution based on the Checklist scores: Cluster 1 'Not at psychotic risk'; Cluster 2 'At intermediate risk'; Cluster 3 'With psychotic onset'. The multivariate analysis of the variance of personality traits shows significant differences among the clusters in negative affect, detachment and disinhibition. Higher scores in these traits may distinguish individuals, not at psychotic risk from those at intermediate risk or with psychotic onset. Moreover, social functioning was found to be negatively associated with clusters of psychotic risk.

CONCLUSION

Findings from this study highlighted the need to evaluate personalized interventions targeting such personality traits that could prevent psychotic transition and promote psychological well-being.

The Machiavellian bully revisited: A closer look at differences and processes of Machiavellian bullying and cyberbullying perpetration

Numerous studies on personality traits conducive to traditional bullying and cyberbullying mentioned Machiavellianism as an influential predictor of these behaviors. Machiavellianism comprises manipulative, egotistic orientations that help acquire desired outcomes. However, it is questionable whether bullying and cyberbullying reflect unidimensional constructs since they are frequently categorized into verbal, relational, and physical aspects (with the latter being applicable only in traditional bullying). Similarly, evidence suggests that Machiavellianism is not a uniform trait. In this research, using a sample of 634 students (339 girls; 54%) from 40 classes from eighth to tenth grades, a five-dimensional measure of bullying and cyberbullying was devised and suggested that aspects of (cyber)bullying are related but still separable. Subsequently, differential relations between the five forms of (cyber)bullying and two facets of Machiavellianism were modeled. Those facets were Machiavellian approach (i.e., manipulative aspects of Machiavellianism) and Machiavellian avoidance (i.e., distrustful aspects of Machiavellianism). Multilevel models revealed that Machiavellian approach predicted relational bullying (but not relational cyberbullying) and Machiavellian avoidance predicted verbal (cyber)bullying and physical bullying. All links were mediated by overt dehumanization, that is, the tendency to cognitively deprive a person of typically human characteristics.

Troll story: The dark tetrad and online trolling revisited with a glance at humor

Internet trolling is considered a negative form of online interaction that can have detrimental effects on people's well-being. This pre-registered, experimental study had three aims: first, to replicate the association between internet users' online trolling behavior and the Dark Tetrad of personality (Machiavellianism, narcissism, psychopathy, and sadism) established in prior research; second, to investigate the effect of experiencing social exclusion on people's motivation to engage in trolling behavior; and third, to explore the link between humor styles and trolling behavior. In this online study, participants were initially assessed on their personality, humor styles, and global trolling behavior. Next, respondents were randomly assigned to a social inclusion or exclusion condition. Thereafter, we measured participants' immediate trolling motivation. Results drawn from 1,026 German-speaking participants indicate a clear correlation between global trolling and all facets of the Dark Tetrad as well as with aggressive and self-defeating humor styles. However, no significant relationship between experiencing exclusion/inclusion and trolling motivation emerged. Our quantile regression findings suggest that psychopathy and sadism scores have a significant positive effect on immediate trolling motivation after the experimental manipulation, whereas Machiavellianism and narcissism did not explain variation in trolling motivation. Moreover, being socially excluded had generally no effect on immediate trolling motivation, apart from participants with higher immediate trolling motivation, for whom the experience of social exclusion actually reduced trolling motivation. We show that not all facets of the Dark Tetrad are of equal importance for predicting immediate trolling motivation and that research should perhaps focus more on psychopathy and sadism. Moreover, our results emphasize the relevance of quantile regression in personality research and suggest that even psychopathy and sadism may not be suitable predictors for low levels of trolling behavior.

Leader Humor and Followers’ Change-Oriented Organizational Citizenship Behavior: The Role of Leader Machiavellianism

The purpose of this study is to explore the mechanisms by which leader humor affects followers’ change-oriented organizational citizenship behavior. Specifically, we examine the mediation effect of team commitment in the leader humor–change-oriented organizational citizenship behavior link and whether it varied by leader Machiavellianism. Using multi-sourced data from the four battalions of the Republic of Korean Army, our findings show that team commitment mediated the positive relationship between leaders’ affiliative humor and followers’ change-oriented organizational citizenship behavior. Furthermore, the mediated relationship was stronger when leader Machiavellianism was lower. On the other hand, we found no support for the negative relationship between leaders’ aggressive humor and followers’ change-oriented organizational citizenship behavior. Theoretical and practical implications are discussed.

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.
