Zara et al. (2023) provide novel findings into how psychopathy may develop, showing that early life predictors of poor relationships (e.g. being unwanted before birth) are predictive of psychopathy in adulthood. The authors provide a theoretical interpretation of why psychopathy might develop based on these findings by using an adaptive perspective, suggesting that psychopathy may protect or shield individuals from poor relationships. This commentary aims to critically evaluate and extend this latter suggestion in hopes of fostering further research and clarity on the topic.

After presenting an overview of evolutionary perspectives, a summary and elaboration are presented of the interpretation that psychopathy may be an adaptive response that functions to protect individuals from poor relationships. Then, an additional adaptive interpretation is offered.

Psychopathy describes a collection of traits and behavior that facilitates an approach-oriented and exploitative motivational style that might suggest more than a protective function. When negative or poor relationships are experienced (e.g. being unwanted), it is suggested that psychopathy may begin to develop not just for protection (If I am not loved, I will shield myself from those around me) but to actively orient toward exploitation (If I am not loved, I will exploit those around me).

This commentary hopes to arouse further interest into the theoretical interpretations of why psychopathy may develop that are based on findings of how psychopathy develops. These considerations are consequential for understanding what to target in treatments that aim to meet the specific needs and motivations of individuals with psychopathic traits.

This paper aims to present new evidence from the Cambridge Study in Delinquent Development (CSDD) showing the extent to which obstetric (e.g. abnormal birth weight, confinement at birth, severe abnormality of pregnancy, etc.) and early childhood and family factors (illegitimate child, unwanted conception, family overcrowding, etc.) have predictive effects on psychopathic traits measured later in life at age 48 years.

Data collected in the CSDD are analysed. This is a prospective longitudinal study of 411 London men from age 8 to age 61 years.

The results suggest that none of the obstetric problems were predictive of adult psychopathy. However, some other early childhood factors were significant. Unwanted conception (by the mother) was significantly associated with high psychopathy. The likelihood of being an unwanted child was higher when the mother was younger (19 years or less), and when the child was illegitimate. The poor health of the mother and living in an overcrowded family were also significant in predicting psychopathy in adulthood, as well as both psychopathic personality (F1) and psychopathic behaviour (F2).

These findings suggest the influence of very early emotional tensions and problematic social background in predicting psychopathic traits in adulthood (at age 48 years). They also emphasise the importance of investigating further the very early roots of psychopathic traits.

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.

The purpose of this paper is to clarify whether the dark side of personality adds information beyond the bright side when predicting career success.

In total, 287 participants (150♀, M_age=37.74 and SD_age=10.38) completed questionnaires on the Dark Triad (narcissism, Machiavellianism and psychopathy) and the Big Five (emotional stability, extraversion, openness, agreeableness and conscientiousness). They also provided information on their objective (salary and leadership position) and subjective (job satisfaction and satisfaction with income) career success. Regression analyses were used to estimate the Dark Triad’s incremental predictive value.

The results show that the Dark Triad only provides incremental information beyond the Big Five when predicting salary (ΔR²=0.02*) and leadership position (ΔR²=0.04*). In contrast, the Dark Triad does not explain unique variance when predicting job satisfaction or satisfaction with income.

The exclusive use of self-rated success criteria may increase the risk of same-source biases. Thus, future studies should include ratings derived from multiple perspectives.

Considering the Dark Triad in employee selection and development seems particularly promising in the context of competitive behaviour.

The results are discussed in light of the socioanalytic theory. This may help to better understand behaviour in organisational contexts.

This study is the first that simultaneously investigates all three traits of the Dark Triad and the Big Five in combination with objective and subjective career success. In addition, it extends previous findings by answering the question of whether the Dark Triad offers incremental or redundant information to the Big Five when predicting success.

The purpose of this study was to analyze the moderating role of micro-events on the relationship between the three Dark Triad dimensions and counterproductive work-brehaviors. The social exchange theory and the person–situation interactionist model supported this study’s model that analyzed whether micro-events at work would moderate the relationship between the three dimensions of the dark triad personality (Machiavellianism, psychopathy and narcissism) and specific types of counterproductive work behaviors (CWB; toward the organization, and the individual).

To achieve this goal, this study used a sample of 241 currently employed participants.

The results showed that individuals who scored higher on their dark triad traits engaged more frequently in CWB; however, when they experienced more daily uplifts than daily hassles, their CWBs significantly decreased.

The cross-sectional design should be regarded as a limitation, and the authors assessed all the variables through self-reported measures.

Such results proved to be fundamental for a better understanding of employees’ behavior, as well as the impact of micro-events in the organizational settings.

This study aims to examine the relationships between personal (emotional intelligence, Dark Triad (DT), core self-evaluation and burnout) and situational variables (organizational justice) and organizational citizenship behavior (OCB) (supervisor report) and counterproductive work behavior (CWB) (self-report).

In total, 680 questionnaires were distributed to teachers in 20 Arab elementary schools in Northern Israel. Usable questionnaires were returned by 509 teachers (75%). The questionnaires covered emotional intelligence, DT, core self-evaluation, organizational justice, burnout, CWB and demographic characteristics. Their principals filled out questionnaires on the teachers’ in-role performance and OCB.

Results showed that CWB was mostly related to higher levels of psychopathy, lower levels of emotional intelligence (ability to use emotions) and higher levels of burnout (emotional exhaustion). OCB was related to higher levels of procedural justice, lower levels of burnout and higher levels of emotional intelligence.

Organizations should consider ways to reduce burnout, which may reduce CWB and increase perceptions of justice, thereby promoting OCB.

Two novel aspects are noteworthy. First, this study simultaneously examines both CWB and OCB to clarify the similarities and differences between them. Second, few studies have examined the correlates of CWB and OCB in Arab culture.

The purpose of this paper is to examine the psychometric characteristics of male offenders who joined a democratic therapeutic community and their relationship to attrition.

Residents who left therapy prematurely during the assessment phase (N = 46) and residents who left therapy prematurely during core therapy (N = 202) were compared to residents who completed therapy (N = 52) on two psychometric measures: Raven’s Standard Progressive Matrices and The Blame Attribution Inventory.

A multinomial logistic regression analysis showed higher levels of external blame can predict attrition during therapy; those with higher levels of external attribution are significantly more likely to leave therapy prematurely, including both during the assessment phase and during core therapy. Raven's Standard Progressive Matrices score did not significantly predict whether an individual left therapy prematurely.

Support was found for existing research within the academic evidence base. The findings have both empirical and clinical utility, suggesting during the assessment phase of therapy, practitioners can identify residents that may require additional support to maintain engagement, minimising the potential for premature departure. The implications of the findings are discussed, with suggestions made for future research.

This study aims to validate the money management intention screening questionnaire under the framework of theory of planned behavior, which includes attitude, subjective norms, perceived behavioral control and intention.

A total of 919 undergraduate students with loans were randomly selected and grouped into four sub-studies to address the psychometric properties of the imposed structure. The item–object congruence, confirmatory factor analysis (CFA), test–retest reliability method and other statistical tests were carried out for item selection and confirmation. Two self-reported measures, namely, Saving Behavior Scale and Short Dark Triad (SD3-Thai version), were applied for the measure concurrent validation.

The final 12 items with four-component structures were deemed reliable and generally valid in university students with loans, with CFA results indicating good fit indices (χ² = 96.44, df = 43; CFI = 0.96; GFI = 0.94; RMSEA = 0.06). The test–retest method indicated values between 0.66 (subjective norm) and 0.71 (attitude). Machiavellianism from SD3-TH and saving attitude from the Saving Behavior Scale showed the strongest significant relation among the items. The abbreviation of the 12-item structure was labeled in the Money Management Intention Questionnaire (MMIQ-TPB).

This study provided a reliable and valid substantial structure for identifying money management intention. However, there was a consideration that MMIQ-TPB questions referred to cognitive influences through intention; thus, it was designed to cover the intended preparation and not in the action stage.

Great money management practically predicts a lower likelihood of being in debt. Attentive educators or loan providers can thus benefit from this alternative structure as a screening scale for identifying risky cognitive mismanagement.

The evidence provided in this study highlights the possibility of identifying students who necessarily need a program to improve their monetary management skills during their studying periods. Policymakers could address this problem at the first stage of the general mode in the loan providing operation.

This study bridges the gap in the literature on financial behavioral changes for establishing money management intention among undergraduate students with loans. Furthermore, it confirms the advantages and disadvantages of having certain dark personality traits in a financial context.
