The sexual double standard (SDS) has traditionally been studied by examining evaluations of hypothetical targets. Although much knowledge has been gained regarding the SDS by using this methodology, the literature thus far has suffered from a lack of ecological validity. The goal of the present study was to determine whether the SDS emerged in evaluations of participants’ real-life friends and acquaintances. Participants (n = 4,455) evaluated a single, randomly assigned male or female friend or acquaintance whose sexual history they were familiar with. Women were evaluated more negatively as their number of sexual partners increased, whereas number of partners was not related to evaluations of men. The SDS was not moderated by the closeness of the relationship between the participant and the target person. (PsycINFO Database Record (c) 2019 APA, all rights reserved)
