The convergence of Machiavellianism, narcissism, psychopathy and sadism is known as the “Dark Tetrad.” Our understanding of the relationship between the Dark Tetrad, harassment and Rape Myths is limited. While men are more likely to blame victims of sexual violence, it is unclear how gender influences the ability to perceive harassment. The aim of the present study is to look at the relationship between dark traits, gender, Rape Myths and perception of harassment. A sample of N = 210 university students located in England & Wales were recruited on SONA and social media platforms. Student’s t-tests, Pearson’s correlations, and multiple linear regressions were conducted. Analyses revealed gender differences for both Rape Myths endorsement and perception of harassment. Furthermore, a relationship between the dark traits, Rape Myths and perception of harassment was founded. These results have several implications, including our ability to understand perpetrators’ characteristics, the impact of the Dark Tetrad on Rape Myths and perception of harassment, and our ability to develop effective prevention programs.
