Across two studies (N _TOTAL = 933), a person’s willingness to engage in a relationship with those scoring high in each of the Dark Triad traits (i.e., Machiavellianism, narcissism, and psychopathy) was examined as a function of their own levels of the Dark Triad traits and the relationship type in question (i.e., a one-night stand, a dating relationship, or a marriage). There were three notable findings. First, those scoring high in Machiavellianism, narcissism, and psychopathy were more willing to engage in a relationship with a person who was also high in Machiavellianism, narcissism, and psychopathy, respectively. Second, as the commitment level of the relationship increased, so did a narcissistic individual’s willingness to engage in a relationship with a fellow narcissist. Third, psychopathic people were generally interested in having one-night stands, seemingly without concern for the personality traits of the other person involved. Results are discussed in relation to assortative mating.

在两个研究（ñ _TOTAL= 933），我们会根据个人自身对黑暗三合会特质及其关系的等级，来考察一个人与那些在每个黑暗三合会特质（即马基雅维利主义，自恋和心理疾病）中得分高的人建立关系的意愿。输入有问题的类型（例如，一夜情，约会关系或婚姻）。有三个值得注意的发现。首先，那些在马基雅维利主义，自恋和精神病中得分较高的人更愿意与一个在马基雅维利主义，自恋和精神病中也较高的人建立关系。其次，随着恋爱关系水平的提高，自恋者与自恋者建立关系的意愿也增加了。第三，精神病患者通常对一夜情感兴趣，似乎不必担心其他参与人员的个性特征。讨论了关于配偶交配的结果。
