Narcissism and psychopathy were positively linked with higher sexual motivation, self-esteem, and assertiveness, & negatively related to anxiety & fear; in the end, they have more fun

Evidence for the superordinate predictive ability of trait psychopathy: The Dark Triad and quality of sexual life. Benedikt Steininger, Jakob Pietschnig. Personality and Individual Differences, Volume 193, July 2022, 111620. https://doi.org/10.1016/j.paid.2022.111620

Abstract: Novel evidence indicates that quality of sexual life is linked to the Dark Triad personality traits. However, results of Dark Triad research have often remained unreplicated, thus questioning the validity of observed effects. Here, we conceptually replicate and extend previous findings on the links of the Dark Triad to the quality of sexual life (i.e., sexual self-concept and generalized sexual satisfaction components) in a large, community-based sample (N = 896, 72% women, mean age = 28.1 years). Participants completed online self-assessments of narcissism, Machiavellianism, psychopathy, and the quality of their sexual lives. Regression analyses showed that all dark traits were positively associated with higher sexual preoccupation, but narcissism and psychopathy were positively linked with higher sexual motivation, self-esteem, and assertiveness, yet negatively related to anxiety and fear. Higher Machiavellianism scores were linked to more negative emotions and lower sexual motivation, self-esteem, assertiveness, and satisfaction. While aversive personality traits were predictive of sexual self-concept and satisfaction, the superordinate predictive value of trait psychopathy raises concerns about the validity of the conceptualization of the Dark Triad as three overlapping, yet sufficiently distinct personality traits. We show that psychopathy appears to be the most important aversive personality trait driving quality of sexual life.

4. Discussion

In the present study, we demonstrate non-trivial influences of dark personality traits on sexual self-concept, sexual satisfaction, and overall quality of sexual life. Excessive thinking about sex (i.e., sexual preoccupation) was positively linked to all dark traits. Effects were small to medium-sized and tended to be most pronounced for subclinical psychopathy. When inspecting the associative pattern by means of multiple regressions, only psychopathy meaningfully predicted being excessively preoccupied with sexual thoughts. This finding is consistent with previous research linking aspects of antisocial behavior, practices, as well as impulsivity to an increased preoccupation with sexuality (Lee & Forbey, 2010).

The motivation to be sexually active was linked to all dark traits (excepting Machiavellianism which only yielded effects for men). Therefore, while it seems conceivable that psychopathy and narcissism increase the desire for sexual interaction, Machiavellianism may not. This idea is consistent with previous research linking narcissism and psychopathy to an increased sex drive, which does not apply to Machiavellianism once the other dark traits are controlled for (Baughman et al., 2014). However, in our study only psychopathy was meaningfully and positively associated with the motivation to be sexually active when the other Dark Triad traits were simultaneously investigated.

Narcissism and psychopathy were both positively related to cognitive dimensions of SSC (i.e., sexual self-esteem and assertiveness), while Machiavellianism was not. In the multiple regression models, a negative relationship between Machiavellianism and sexual self-esteem, as well as assertiveness, could be observed in women. It thus appears that while narcissism and psychopathy may increase one's enjoyment of sexuality and the confidence to express one's sexual desires, Machiavellianism tends to have the opposite result in women, thereby possibly being obstructive to a satisfactory quality of sexual life. The same pattern was observed previously between Dark Triad traits and assertiveness (Petrides et al., 2011). This may mean that higher general assertiveness in those high in narcissism and psychopathy may also accompany higher sexual assertiveness, thereby contributing to an improved quality of sexual life.

Sexual anxiety and fear were negatively linked to narcissism and psychopathy, while they were positively associated with Machiavellianism in women and the overall sample. It seems plausible that those high in psychopathy are less prone to experience negative emotions related to their sexual lives, because of an inherent lack of fear and anxiety (e.g., Lilienfeld & Andrews, 1996). Previous research demonstrated negative relationships between extraverted and antagonistic narcissism with fear (Sauls & Zeigler-Hill, 2020). It therefore appears that the tendentially carefree nature of those high in narcissism also extends into their sex lives. Contrarily, the increased amount of sexual anxiety and fear pertaining to those high in Machiavellianism is consistent with the previously discussed lower levels of sexual self-esteem and assertiveness, and suggests that for individuals high in Machiavellianism, sexual activity may be a source of stress and discomfort.

Narcissism in women as well as psychopathy in men and women was associated with a larger number of sexual partners. This finding conforms to recent evidence linking both psychopathy and narcissism to an increased number of sexual partners (Borráz-León & Rantala, 2021). In the multiple regression models, only psychopathy positively predicted the number of partners. Our observation of narcissism being virtually unrelated to the number of sexual partners in women and negatively associated with the number of sexual partners in men contrasts prior accounts of narcissism being moderately (and positively) correlated with sociosexuality in this group (Sevi, 2019). The positive association between psychopathy and number of lifetime sexual partners fits well to extant research linking psychopathy to higher sociosexuality (Burtăverde et al., 2021Sevi, 2019).

In terms of the generalized satisfaction with sexual life, there was a trivial negative relationship with Machiavellianism in women and the overall sample, while it was positively, but weakly correlated with Psychopathy in men. When these traits were entered simultaneously in regression models, Machiavellianism meaningfully predicted sexual satisfaction negatively but psychopathy positively.

Here, narcissism and psychopathy were characterized by higher sexual preoccupation, sexual motivation, sexual self-esteem, sexual assertiveness, and, in turn, lower levels of sexual anxiety and fear. Additionally, those high in psychopathy indicated a greater number of lifetime sexual partners and a higher generalized satisfaction with their sexual lives. This may mean that people who are high in psychopathy and narcissism approach their sexuality with more self-confidence and positive feelings than others, while the personality traits can also to some extent be protective against negative emotions related to one's sexual life.

Regarding narcissism, these results fit well with previous findings linking narcissism to higher life satisfaction, positive affect, self-esteem, and subjective well-being (Aghababaei & Błachnio, 2015Womick et al., 2019). The pattern appears to be less clear when it comes to psychopathy, which has been shown to be negatively linked to life satisfaction and flourishing (Van Groningen et al., 2021).

Conversely, those high in Machiavellianism, reported lower sexual self-esteem, sexual assertiveness, and satisfaction with their sexual lives. Machiavellianism was associated with higher levels of sexual anxiety and fear. In contrast to narcissism and psychopathy, Machiavellianism appears to be linked to increased negative emotions regarding the sexual aspects of life, which suggests a lower quality of sexual life. These findings corroborate previous findings linking Machiavellianism to various negative (sexuality-related) outcomes, like decreased relationship satisfaction (Brewer & Abell, 2017), engaging in sexual activity out of insecurity (Brewer & Abell, 2015), and lower subjective well-being as well as meaning in life (Womick et al., 2019).

However, inspecting the unique predictive value of the Dark Triad traits by means of multiple regressions, as has been argued in previous research (Furnham et al., 2013), raises another concern. In doing so, we found that trait psychopathy tended to be the most – and in some cases only – meaningful predictor of various subscales of SSC and the quality of sexual life. For example, when accounting for the shared variance between the Dark Triad, psychopathy remained the only meaningful predictor of sexual preoccupation, sexual motivation, and the number of lifetime sexual partners (unexpectedly excepting narcissism).

When comparing zero-order correlations with their respective multiple regression weights, the loss of predictive power of the narcissism construct in favor of psychopathy seems especially noteworthy, because it hints at the conceptual volatility of the conceptualization of the Dark Triad as three overlapping, yet sufficiently distinct traits, as initially proposed (Paulhus & Williams, 2002). For example, it has been often noted that neither narcissism nor Machiavellianism meaningfully predict outcome variables of interest, like malevolent behavior, once controlling for trait psychopathy (Muris et al., 2017). Furthermore, a single Dark Core – as opposed to a Dark Triad – has repeatedly been demonstrated to represent a better fitting conceptualization of the dark personality, with the Dark Core being predominantly driven by the psychopathy facets callousness and manipulation (e.g., Bertl et al., 2017), thereby once more hinting at the superordinate position of the psychopathy construct within the Dark Triad.

4.1. Limitations

Some limitations of the present study need to be acknowledged. On the one hand, we excluded participants who identified as homosexual and asexual, which limits the generalizability of our findings. However, these inclusion criteria were adopted to allow meaningful comparisons with the so far only available prior study about this topic (Pilch & Smolorz, 2019).

On the other hand, participants filled-in their self-reports online which necessarily entails the well-known drawbacks of online-administered questionnaires (e.g., no controlled environments, no possibility to check participant attention). However, this approach ultimately allowed us to recruit a comparatively large number of participants beyond mere student samples.

Finally, because we aimed at increasing comparability with the extant Dark Triad literature, we exclusively relied on the SRP-III as a measure of psychopathy. Considering the superordinate predictive ability of trait psychopathy regarding the quality of sexual life, future researchers may wish to compare different models and conceptualizations to increase our understanding of this link.

4.2. Conclusion

Here we show that Dark Triad traits are associated with increased sexual preoccupation. Participants scoring higher in narcissism and psychopathy are characterized by an overall better quality of sexual life, while individuals scoring high on Machiavellianism tend to report more negative sexuality-related outcomes, showing a lower quality of their sexual experience. Notwithstanding, when controlling for the shared variance between the Dark Triad traits, psychopathy appears to be the most potent predictor of SSC and quality of sexual life, ultimately questioning the incremental validity of the Dark Triad framework. Thus, psychopathy appears to be the most important aversive personality trait driving quality of sexual life.
