Researchers have identified narcissism and everyday sadism as key drivers of heightened sexual desire and increased consumption of pornography.


A groundbreaking new study, published in Personality and Individual Differences, sheds light on the intriguing link between certain "dark" personality traits and sexual behavior. Researchers have identified narcissism and everyday sadism as key drivers of heightened sexual desire and increased consumption of pornography.

The study focuses on the notorious "Dark Tetrad"—a quartet of personality traits associated with manipulative and harmful behaviors. These traits include narcissism, Machiavellianism, psychopathy, and everyday sadism. Narcissism, often associated with a grandiose sense of self and a lack of empathy, stands out in this research for its robust connection to sexual motivation. Everyday sadism, marked by pleasure derived from inflicting discomfort or harm on others, also emerged as a significant predictor of sexual drive.

Previous research into the Dark Tetrad suggested surprising links between these traits and sexual behavior, but the current study sought to delve deeper. "My co-authors and I are continuing to explore the four dark personalities comprising the so-called Dark Tetrad. In particular, we were trying to replicate surprising findings from an earlier study: Namely that narcissism and sadism — not psychopathy — predicted higher sex drive," explained Delroy L. Paulhus, a professor of psychology at the University of British Columbia and one of the lead authors.

Psychopathy, often characterized by impulsivity and emotional coldness, was once thought to be the primary predictor of sexual behavior. However, this new study shifts the spotlight onto narcissism and sadism. Utilizing precise measurements and adding pornography consumption as a new indicator, the research revealed that these two traits consistently correlated with higher sexual motivation.

The study involved two large groups of undergraduate students from the University of British Columbia and the University of Winnipeg. In the first phase, 701 students, ranging in age from 17 to 29, completed an online survey assessing their personality traits and sex drive. The second part of the study replicated the experiment with 400 participants, some of whom were reassessed five months later to confirm the reliability of the results.

The findings were clear: narcissism and sadism stood out as the most significant predictors of sex drive, with the relationship between these traits and sexual motivation remaining strong over time. "We were surprised when our earlier study found sadism predicted sex drive, but our current study replicated that finding twice," Paulhus told PsyPost.

Moreover, the study found that these dark traits influenced not just sex drive but also pornography use. The researchers noted that men scored higher on both dark traits and sexual motivation than women, a finding consistent with prior gender research.

In an interesting twist, the study also found that relationship status had no significant effect on the association between dark traits and sex drive. This discovery suggests that narcissism and sadism are linked to sexual motivation on a deeper, more psychological level, rather than simply reflecting opportunities for sexual encounters through relationships. "There is an important difference between one’s frequency of sexual liaisons and personally experienced sex drive," Paulhus emphasized. He cited the example of "incels," individuals with high sex drives but limited sexual opportunities due to a lack of personal attractiveness.

While these findings illuminate new aspects of the relationship between dark personality traits and sexual behavior, the study does come with some limitations. The reliance on self-reported data raises questions about the accuracy of participants' responses, particularly in terms of sex drive and pornography use. Additionally, the focus on college-aged individuals limits the scope of the research, leaving open the question of whether these patterns hold true across different age groups.

Future research will likely explore more nuanced mechanisms behind the link between narcissism, sadism, and sexual motivation, potentially providing deeper insights into how these dark traits shape behavior throughout the lifespan.

Authored by Paul D. Trapnell, Megan M.L. Poulter, and Delroy L. Paulhus, this study continues to push the boundaries of understanding the complex interplay between personality and sexuality.
