Narcissism and psychopathy are closely linked in women serving prison sentences

A recent study of incarcerated individuals reveals that grandiose, narcissistic personality traits are closely linked to psychopathic tendencies, partially because people with these traits use manipulative strategies to navigate prison environments. This direct relationship between narcissism and psychopathy is especially pronounced in incarcerated women. The research was published in Psychology, Crime & Law.

The Dark Triad is a psychological framework that groups together three aggressive and self-centered personality traits. These include narcissism, which involves an inflated sense of self-importance; Machiavellianism, characterized by a manipulative and cynical approach to others; and psychopathy, marked by emotional coldness, moral disengagement, and a lack of empathy. In everyday settings, psychologists often view these three traits as related but distinct behavioral patterns.

In a restrictive environment like a prison, these personality features can blend together into active survival tactics. Correctional facilities force constant competition for limited resources and informal privileges. Because overt aggression can attract swift formal or informal sanctions, inmates often rely on covert manipulation to maintain their social standing.

Health researcher Gizell Green of the Max Stern Yezreel Valley College in Israel, along with crisis management and security scholars Alena Lochmannová and Ondřej Kolář of the Police Academy of the Czech Republic, wanted to understand how these traits operate under the constraints of incarceration. The researchers proposed that an innate sense of narcissistic entitlement might not automatically lead to psychopathic behavior. Instead, they hypothesized that an intermediate step of calculated manipulation connects the two. They also wanted to investigate whether this behavioral pathway looked different between men and women in custody.

To test these ideas, the researchers surveyed 344 adults serving time in six different Czech prisons. The group included 205 women and 139 men. Participants filled out a demographic questionnaire and a brief psychological assessment known as the Dirty Dozen. This assessment uses a twelve-item rating scale to measure the presence of the three Dark Triad traits.

To encourage honest answers about antisocial behavior, the researchers used a locked collection box so that prison staff could not match responses to specific individuals. The team then used statistical modeling to map the relationships among the three personality traits. Their models accounted for background factors like age, marital status, and the number of children each participant had, as these demographic details can influence criminal trajectories and baseline personality expressions.

The results showed strong associations among all three dark personality traits in the prison sample. Narcissism was robustly linked to elevated levels of Machiavellian tendencies. Both narcissism and Machiavellianism also directly predicted higher levels of psychopathy.

When analyzing the pathways between these traits, the researchers found that Machiavellianism acts as a psychological bridge. Narcissistic desires for dominance and admiration translate into psychopathic callousness partly through the use of calculating and manipulative strategies. In the context of a prison, where informal hierarchies dictate social standing, manipulation functions as a practical tool to secure resources without exposing personal vulnerability. This repeated strategic behavior can foster the emotional detachment characteristic of psychopathy.

The researchers also looked at whether gender changed these behavioral pathways. Their statistical model did not allow the indirect pathway linking narcissism to psychopathy through manipulation to vary by gender, so it was treated as the same for men and women rather than tested for differences. The direct link between narcissism and psychopathy, however, varied measurably depending on gender. For incarcerated women, the direct association between narcissistic traits and psychopathic traits was almost twice as strong as it was for incarcerated men.

In women’s prisons, a grandiose sense of entitlement is more likely to be paired with severe interpersonal hostility and emotional coldness. Female offenders who display pronounced narcissistic behavior represent a more extreme deviation from traditional gender expectations. The researchers suggest this deviation often reflects a more deeply rooted personality pathology that closely aligns with psychopathy.

These findings offer practical guidance for correctional staff managing risk and rehabilitation. Assessment protocols should avoid treating high scores on Dark Triad tests as a single, undifferentiated warning sign. Recognizing how a person’s pursuit of status translates into exploitative tactics can help staff identify inmates who might resort to coercive behavior. Rehabilitation programs can then focus on addressing these specific manipulative strategies rather than just enforcing general rule compliance.

Because the researchers collected all their data at a single point in time, the study cannot establish a definitive sequence of cause and effect. It remains possible that the prison environment first encourages manipulative behavior, which then brings out dormant narcissistic or psychopathic tendencies. The study also lacked a comparison group of people living outside the prison system. Without this baseline, it is impossible to know if this specific blending of personality traits is unique to the custodial environment.

The psychological survey used in the study is brief and might not capture the full range of behaviors associated with psychopathy. Participants in a prison setting might also adjust their answers to protect their reputations, even with anonymous collection methods. Expanding on these findings will require incorporating longer psychological evaluations and reviewing official behavioral records. Observing how these traits manifest in different international justice systems could help clarify how specific prison cultures shape antagonistic behavior.
