Abstract: Heterosexual intercourse serves the evolutionarily adaptive function of reproduction and gene propagation. However, engaging in sexual intercourse also entails risks in contracting Sexually Transmitted Infections (STIs) that bring about pain and health complications. While STIs typically do not pose a direct threat to one's life, the Human Immunodeficiency Virus (HIV), a relatively recent emergent STI, does. Also, unlike other existing STIs such as Gonorrhea, people infected with HIV typically do not display obvious symptoms that would prompt preventive actions from their sexual partners. Accordingly, consistent condom usage (or lack thereof) has become one of the top concerns of HIV prevention efforts. In this paper, we examine general intelligence, which enables one to cope effectively with evolutionarily novel situations and issues, as a predictor of condom usage in response to the threat of HIV. In Study 1, we found that individuals with higher levels of general intelligence exhibited greater openness to using condoms. In Study 2, we found that individuals with higher levels of general intelligence exhibited greater likelihood of using condoms in a sexual offer scenario—but only when primed with the threat of the evolutionarily novel STI HIV. Implications and future directions are discussed.
