Consent is central to many of today's most pressing social issues: What counts as sexual assault? Whom are the police allowed to search? Can they use people's data like that? Yet despite the fact that consent is in many ways an inherently psychological phenomenon, it has not been a core topic of study in psychology. Although domain-specific research on consent-most commonly, informed consent and sexual consent-is regularly published in specialty journals (e.g., methods and sex-research journals), consent has been largely ignored as a generalizable psychological phenomenon. This has meant that consent has been mostly excluded from "mainstream" psychology as a core topic of study. This omission is particularly striking given that psychologists have paid broad attention to related constructs, such as compliance, obedience, persuasion, free will, and autonomy, and that scholars in other fields, such as law and philosophy, have paid considerably more attention to the topic of consent, despite its uniquely psychological qualities. In this article, I argue that psychologists should embrace consent-in particular, the subjective experience of consent-as a core topic of study.
