Swear Word Fluency, Verbal Fluency, Vocabulary, Personality, and Drug Involvement

Abstract. Swearing is stereotypically associated with socially undesirable traits and behaviors, including limited verbal ability, disagreeable personality, and alcohol use. We sought to demonstrate that, contrary to such stereotypes, swear word fluency (i.e., ability to generate swear words) does not arise from a lack of verbal skills. We also explored whether swear word fluency might serve as an index of personality traits related to drug use. Accordingly, we conducted a preregistered study in which 266 undergraduates at a US university ( Mage = 19.36; 66.9% self-identified as women and 49.6% as White) completed measures of swear word fluency, verbal fluency (i.e., overall ability to generate words), vocabulary, Big Five traits, sensation seeking, and drug use. We observed positive associations between swear word fluency and verbal fluency, vocabulary, Openness, and Extraversion, and a negative association with Agreeableness. Moreover, swear word fluency accounted for unique variance in self-reported drug use over and above that accounted for by personality and general verbal ability. Swear word fluency might serve as one of few tasks where higher scores predict more drug involvement, justifying further work linking this measure with other aspects of personality and drug use.
