The current study investigated the influence of Machiavellianism, a personality trait characterized by a manipulative interpersonal style and willingness to exploit others (Christie & Geis, 1970), on three areas of sexual behavior. Men (N = 90) and women (N = 192) aged 18–81 years (M = 25.82, SD = 9.85) completed the Mach IV (Christie & Geis, 1970), YSEX Questionnaire (Meston & Buss, 2007), Sex...

In two studies, we investigated how bitter taste preferences might be associated with antisocial personality traits. Two US American community samples (total N = 953; mean age = 35.65 years; 48% females) self-reported their taste preferences using two complementary preference measures and answered a number of personality questionnaires assessing Machiavellianism, psychopathy, narcissism, everyd...

The present study examined whether the relationship between Dark Triad (DT) of personality and problematic smartphone use (PSU) can be explained by mediating role fear missing out (FoMO). FoMO in this has yet to examined. A total 457 participants completed an online survey. Results indicated that males scored high on measures assessing DT personality, while females PSU. Structural equation mode...

Previous studies have shown that environmental concerns (ECs) can be reduced to a three-factor model - comprising altruistic, biospheric, and egoistic concerns - but there have been few studies examining individual difference predictors of ECs. In this study with 203 individuals from a British community sample, we show that biospheric concern was significantly associated with participants' age,...

We examined how the Dark Triad (i.e., narcissism, psychopathy, and Machiavellianism) traits—as different social strategies—were associated with various health outcomes. In samples of American undergraduates (N = 1389), Australian high school students (N = 2023), and British undergraduates (N = 280), we examined the physical, social, and psychological costs associated with the Dark Triad traits....

Which personality traits are associated with physical attractiveness? Recent findings suggest that people high in some dark personality traits, such as narcissism and psychopathy, can be physically attractive. But what makes them attractive? Studies have confounded the more enduring qualities that impact attractiveness (i.e., unadorned attractiveness) and the effects of easily manipulated quali...

Work on the Dark Triad traits has benefited from the use of a life history framework but it has been limited to primarily Western samples and indirect assessments of life history strategies. Here, we examine how the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) relate to two measures of individual differences in life history strategies. In Study 1 (N = 937), we replica...

Despite Allport's early call to study personality as a coordinated system of traits within individual rather than separate traits, researchers often assume personality variables are largely distinct, independent characteristics. In the current research, we examined the usual assumption that Dark Triad traits (narcissism, psychopathy, and Machiavellianism) are best studied using a variable-cente...

The Dirty Do-en is a recently developed, concise measure of the Dark Triad (i.e., narcissism, psychopathy, & Machiavellianism). However, recent evidence has questioned the validity of this scale. In two studies we provide details about this measure in as much as it relates to the Big Five (i.e., Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Openness) whilst controllin...
