The motivation to mate is a universal motive for all sexually dimorphic species, of which humans belong, that facilitates reproductive success. Jealousy is a universal emotion that is adaptive in the context of mate retention. We tested the relationship between the Dark Triad traits and jealousy as well as the moderating effect of mate value (study 1; N = 441) and mating orientation (study 2; N = 298) on the association between the Dark Triad traits and jealousy. We found that perceived mate value moderated the relationship between the Dark Triad traits and jealousy. As such, people high on the Dark Triad traits were more jealous if they had high mate value. Further, mating orientation moderated the relationship between psychopathy and romantic jealousy. Individuals high on psychopathy that were oriented to long-term mating were more jealous compared to individuals high on psychopathy but oriented to short-term mating.

交配的动机是所有两性异形物种的普遍动机，人类属于其中，这有助于繁殖成功。嫉妒是一种普遍的情绪，在保留配偶的情况下是适应性的。我们测试了黑暗三元组特征和嫉妒之间的关系以及配偶价值（研究 1；N  = 441）和交配取向（研究 2；N = 298）关于黑暗三合会特征与嫉妒之间的关联。我们发现感知到的配偶价值调节了黑暗三合会特征与嫉妒之间的关系。因此，如果他们的配偶价值高，那么黑暗三合会特征高的人会更加嫉妒。此外，交配取向调节了精神病和浪漫嫉妒之间的关系。与心理变态程度高但倾向于短期交配的个体相比，心理变态程度高且倾向于长期交配的个体更嫉妒。
