Experimentally Inducing Disgust Reduces Desire for Short-Term Mating

Abstract

Short-term mating strategies involve casual sex, multiple partners, and short-time intervals before initiating intercourse. Such strategies should be difficult to implement in the presence of high levels of sexual disgust. Researchers have therefore suggested—and found evidence for—the hypothesis that individuals with a stronger proclivity for short-term mating have lower levels of sexual disgust. Here, we suggest a related hypothesis: inducing sexual disgust should reduce desire for short-term mating. Experiment 1 (N = 341) and experiment 2 (N = 361) investigated the effects of disgust induction on desire for short-term mating. Both studies found that inducing disgust reduces desire for short-term mating, and that the effect of sexual disgust is particularly strong. These results support the novel hypothesis advanced here and corroborate the broader hypothesis that reduced sexual disgust is a previously undiscovered design feature of short-term mating strategies. © 2018, Springer Nature Switzerland AG.
