When evaluating someone as a potential social acquaintance, people prefer affiliative, pleasant individuals. This necessitates the evolution of perceptual acuity in distinguishing between genuinely prosocial traits and those connoting exploitative intentions. Such intentions can be readily inferred through facial structures connoting personality, even in the absence of other diagnostic cues. We sought to explore how self-reported narcissism, a personality constellation associated with inflated self-views and exploitative intentions, might facilitate one’s ability to detect narcissism in others’ faces as means of identifying social targets who could best satisfy potential exploitative goals. Participants viewed pairs of male and female targets manipulated to connote high and low levels of narcissism before identifying which appeared more narcissistic and indicating their preference among each pair. Narcissistic individuals were no better at accurately identifying other narcissists, but such individuals demonstrated considerable aversion to narcissistic faces. Women higher in exploitative narcissism additionally preferred narcissistic female faces, while men high in exploitative narcissism demonstrated similar patterns of aversion toward narcissistic male faces. Findings provide evidence that narcissistic individuals may adaptively avoid those whom they identify as having similar exploitative behavior repertoire, though when considering the exploitive dimension of narcissism specifically, sex differences emerged.

自恋型人格特质与对面部交流的自恋的准确识别与偏爱之间的关系

当评价某人为潜在的社交对象时，人们更喜欢有亲和力，令人愉悦的人。这就需要在区分真正的亲社会特征和那些包含剥削意图的特征时发展感知敏锐度。即使没有其他诊断线索，也可以通过暗示人格的面部结构轻松推断出这种意图。我们试图探索自我报告的自恋，一种与膨胀的自我看法和剥削意图相关的人格星座，如何促进一个人从别人的脸上发现自恋的能力，以此作为确定最能满足潜在剥削目标的社会目标的手段。参加者查看了成对的男性和女性目标，以表明自己的自恋程度高和低，然后再确定自恋程度，并表明他们在每对中的偏好。自恋者并不擅长准确识别其他自恋者，但这种人表现出对自恋面孔的极大厌恶。剥削自恋较高的女性更喜欢自恋的女性面孔，而剥削自恋较高的男性表现出相似的厌恶自恋男性面孔的模式。研究结果表明，自恋者可以适应性地避开他们认为具有类似剥削行为的人，尽管当特别考虑自恋的剥削维度时，就会出现性别差异。
