Dating app-facilitated infidelity, sexual attitudes, and personality

The study’s abstract highlights a key finding: dating app users, overall, exhibited higher levels of sexual compulsivity compared to non-users. Furthermore, contrary to a prevalent prejudice that dating app users are less trustworthy, the research found that sexual activity via dating apps was more common among users who were already in committed relationships. This suggests that dating apps are utilized not exclusively for seeking new partners but also as a means for infidelity.

Unpacking the Dark Triad and Sexual Compulsivity

The research builds upon existing literature suggesting that individual differences in dating app use can be better predicted by the non-clinical "Dark Triad" traits—narcissism, Machiavellianism, and psychopathy—than by the broader Big Five personality traits. These traits, viewed as quantitative variations along a continuum rather than clinical disorders, are linked to "fast-life history strategies," implying a focus on immediate reproductive opportunities.

Narcissistic individuals are often perceived as charming and are thus frequently selected by others on these platforms. Machiavellians, characterized by their strategic and manipulative tendencies, tend to seek status and dating options that may not lead to long-term relationships, often resulting in strategic dissolution. Psychopaths, known for their thrill-seeking and impulsivity, are more prone to opportunistic hook-ups. Previous research indicated that individuals with elevated Dark Triad traits are more likely to search for and engage in casual sex via dating apps, a phenomenon termed "Tinder-sex." However, this new study sought to determine if these individuals also engage in dating app-facilitated cheating while already in a relationship.

The study also incorporated sexual compulsivity, defined by a lack of impulse control and preoccupation with sex. Previous research linked sexual compulsivity to a higher number of sexual partners, both within and outside of committed relationships. This study aimed to explore the specific association between sexual compulsivity and "Tinder-sex," and how these behaviors might differ based on relationship status.

Sex Differences in Dating App Behavior

A significant portion of the study’s findings centers on sex-based differences in sexual strategies, rooted in evolutionary psychology. The premise is that men and women have evolved distinct preferences and courtship behaviors, particularly for short-term mating. Men, generally, are more open to uncommitted sex, while women tend to be more cautious in partner selection. These differences are often observed universally, even in the context of digital interactions. The study posits that extended messaging on dating apps might create a sense of perceived security for women, thereby facilitating "Tinder-sex."

The research also acknowledges the public health implications of risky sexual behaviors, including increased risks of sexually transmitted infections (STIs), especially when coupled with alcohol consumption. The importance of condom use and contraception in preventing both STIs and unintended pregnancies is underscored.

Key Findings and Data Analysis

The study utilized a sample of 495 participants (288 men, 207 women) aged 16 to 70, with a mean age of 41.99. Data were collected via an online questionnaire. Analyses were stratified by sex.

Overall Trends:

• Dating app users, in general, reported higher levels of sexual compulsivity than non-users.
• Sexual activity via dating apps ("Tinder-sex") was more prevalent among users already in committed relationships for both men and women. This finding directly challenges the stereotype of dating app users being less trustworthy and suggests a role for dating apps in facilitating infidelity.

Sex-Specific Traits and Behaviors:

• Men: Male users who reported engaging in "Tinder-sex" were found to be more Machiavellian and sexually compulsive than those who did not.
• Women: Machiavellian women who were also sexually satisfied were more likely to engage in infidelity via dating apps. Psychopathic men and narcissistic women showed a preference for drinking alcohol during dates.

Condom Use and Contraception:

• No significant differences were found in men’s or women’s attitudes towards condom use based on their relationship status or dating app usage.
• However, women who favored condom use on hook-ups were more Machiavellian than those who did not, irrespective of their dating app use.
• Responsibility for contraception was primarily observed among individuals in committed relationships, regardless of sex. Men who felt responsible for contraception were found to be slightly less sexually compulsive and reported higher sexual satisfaction, but this was more pronounced in those not using dating apps.

Alcohol on Dates:

• Men who considered drinking part of a date were slightly more psychopathic than those who did not.
• Women who viewed alcohol as integral to a date were slightly more narcissistic.

Challenging Stereotypes and Broadening Understanding

The study’s findings offer a more nuanced understanding of dating app users’ behaviors, moving beyond simplistic labels of untrustworthiness. The confirmation that partnered individuals are more likely to engage in "Tinder-sex" highlights the role of dating apps in modern infidelity, a phenomenon previously studied more broadly but now specifically linked to digital platforms.

The research also reinforces the importance of considering sex-specific sexual strategies. While men’s behaviors on dating apps showed less variation based on relationship status, women demonstrated more strategic approaches. For instance, Machiavellian women’s likelihood to forgo condoms during sex (in the context of hook-ups) was contrasted with non-users, suggesting a more calculated approach to risk management in uncommitted sexual encounters. This aligns with the idea that women might adopt more tactical strategies in risky sexual behaviors than men.

The study’s results resonate with international research on infidelity and sexual health. The link between infidelity and personality traits like Machiavellianism and psychopathy, rather than solely cultural differences, was observed. Similarly, the connection between drinking and "Tinder-sex" was personality-driven rather than sex-specific. The findings regarding contraception responsibility, primarily within committed relationships, and the reduced motivation for condom use among those with short-term orientations, suggest that individual lifestyle and personality are paramount in public health considerations for sexual protection behaviors.

Implications for Public Health and Social Psychology

The study’s conclusions have significant implications for public health campaigns and our understanding of social psychology in the digital age. The confirmation that personality traits, particularly the Dark Triad, are strong predictors of risky sexual behaviors on dating apps suggests that interventions might need to be tailored to these personality profiles.

The finding that psychopathic traits in women engaging in dating app use and "Tinder-sex" might be linked to borderline characteristics warrants further investigation. This could indicate unstable relationship patterns and a complex interplay between personality and sexual behavior. The observation that women engaging in "Tinder-sex" reported higher sexual satisfaction could be interpreted as a strategic pursuit of good genes or a means of enhancing self-esteem.

The research underscores that while sexual compulsivity is elevated among dating app users, its manifestation varies. Men, in particular, showed a stronger association between sexual compulsivity, "Tinder-sex," and reduced contraceptive responsibility. In contrast, women’s behaviors, while also influenced by personality, appeared more multifaceted and context-dependent.

Limitations and Future Directions

The researchers acknowledge several limitations. The cross-sectional design prevents causal interpretations, meaning it is impossible to definitively state whether certain personality traits lead to specific dating app behaviors or vice versa. The study’s reliance on data from a predominantly WEIRD (Western, Educated, Industrialized, Rich, and Democratic) population and a focus on apps with a largely heterosexual user base limit the generalizability of findings to other cultural contexts and sexual minorities. The assessment of psychopathy did not capture the impulsivity facet, which could be relevant, particularly in understanding the behavior of hypersexual, borderline women.

Future research could benefit from larger sample sizes to allow for subgroup analyses and exploration of extreme group differences. Investigating users’ and their partners’ mate values could also provide further insights, as self-perceived mate value is linked to cheating. Additionally, the study did not explicitly account for "planful cheaters" who might strategically seek out other partnered individuals for extradyadic sex. Future research should also consider the agentic behavior of individuals in various relationship contexts, given the relatively low levels of social sanctioning expected in online interactions.

Conclusion

In conclusion, this study provides valuable insights into the complex relationship between personality, sexual behaviors, and dating app use. It confirms that dating apps are utilized by both single and partnered individuals, and that personality traits significantly influence the nature of their sexual encounters and attitudes. While male dating app users often exhibit an opportunistic approach, women’s strategies are more varied and complex, influenced by factors such as sexual satisfaction and personality. The findings align with existing intercultural research, emphasizing the universal impact of personality on sexual risk behaviors and infidelity, suggesting that individual differences and lifestyle choices play a more significant role in public sexual health than geographical or cultural divides. The study opens avenues for more targeted public health interventions and a deeper understanding of human sexuality in the digital age.
