New insights into the personal costs of psychopathy

A new study has unveiled important insights into the personal repercussions of living with psychopathic traits. Conducted on undergraduate students and published in the journal Personality and Individual Differences, the research illuminates the relationship between psychopathic personality traits and an individual’s functioning across various domains, including their interpersonal relationships, internalizing behaviors, and overall quality of life.

Psychopathy is is characterized by a constellation of traits that typically includes superficial charm, a lack of empathy or remorse, manipulativeness, egocentricity, impulsivity, and antisocial behaviors. While psychopathy has been extensively studied in relation to its impact on society — often highlighting the link between psychopathic traits and criminal or violent behavior — there has been growing recognition of the need to understand how these traits affect the individuals who possess them.

“Most psychopathic traits are generally undesirable. Although this has primarily been asserted based on the consequences to society, the individual consequences may prove to be just as impactful,” the authors of the study explained.

The new research was rooted in the triarchic model of psychopathy. This model breaks down psychopathy into three core dimensions: boldness, disinhibition, and meanness.

Boldness encompasses traits related to fearlessness, social dominance, and emotional resilience. Individuals high in boldness are often characterized by a strong sense of self-confidence, a tolerance for unfamiliar or dangerous situations, and a capacity to remain calm and assertive under pressure.

Disinhibition is characterized by impulsivity, lack of restraint, and poor behavior control. This dimension reflects the inability to resist immediate or short-term temptations, leading to irresponsible, risky, or antisocial behavior. Individuals high in disinhibition may struggle with planning and foresight, often acting without considering the consequences of their actions.

Meanness refers to a lack of empathy, disdain for close relationships, and a readiness to use others for personal gain. This dimension captures the callous, uncaring, and exploitative aspects of psychopathy. Individuals with high levels of meanness are often indifferent to the harm they cause to others and may engage in manipulative, deceitful, or predatory behavior.

“Many previous studies have been limited by only reporting a total score of psychopathy or utilizing a two-factor model,” the researchers explained. “This study expands current knowledge by using the dimensional triarchic model. By examining a person’s specific variations in traits of meanness, boldness, and disinhibition, insight can be gained into potential impairments they may face.”

Employing two separate studies with undergraduate samples, the researchers utilized previously validated measures adapted to assess the triarchic psychopathy model. The first study involved 277 participants from a large southern university, assessing the relationship between triarchic psychopathy traits and measures of social functioning, personality impairment, quality of life, and impairment in other domains such as self-care and life activities. The second study included 525 participants, focusing on the associations between triarchic psychopathy traits and outcomes related to self-harm, personality functioning, and perceived quality of life.

Disinhibition emerged as the most detrimental trait, showing significant and strong associations with a range of negative outcomes across both studies. Individuals exhibiting higher levels of disinhibition experienced greater impairments in social and personality functioning, reduced quality of life across multiple domains (physical, psychological, social, and environmental), and reported higher perceptions of impairment in cognition and life activities such as work or school. This suggests that disinhibition plays a critical role in the personal costs associated with psychopathy, significantly affecting one’s ability to function effectively in various aspects of life.

Boldness, on the other hand, presented a more variable picture. While it was linked to some positive outcomes, such as a higher quality of life and lower likelihood of self-harm, it also correlated with challenges in empathy and intimacy. This duality suggests that while boldness may confer certain advantages, possibly through increased resilience or fearlessness, it can also impair interpersonal relationships and emotional connections.

Meanness was primarily associated with interpersonal difficulties, indicating that this dimension of psychopathy contributes significantly to problems in social interactions. However, the relationship between meanness and other aspects of personal well-being, such as quality of life, showed variability depending on the measures used. This inconsistency highlights the challenges in understanding the full impact of meanness and suggests that its effects may be contingent on the context in which it is measured.

“It appears that impulsive, antisocial, and disinhibited traits are most strongly associated with personal costs,” the researchers said. “Indeed, they have been tied to more significant impairment, reduced life satisfaction, increased internalizing, and a high risk of self-harm and suicidality. Conversely, bold and fearless-dominant traits appear potentially protective, or more often unrelated, to personal costs.”

However, the research is not without its limitations. The use of undergraduate samples and self-report measures may limit the generalizability of the findings, particularly to clinical or forensic populations where psychopathic traits might manifest differently or with greater intensity.

Additionally, the cross-sectional nature of the study means that causal relationships cannot be established definitively. Future research could address these limitations by incorporating longitudinal designs, diverse populations, and alternative conceptualizations of psychopathy to build on these findings.
