Involuntary celibates (“incels”) refers to a group consisting mostly of heterosexual men that exists predominantly in online spaces. These men are united by a belief that they are victimized by a postfeminist society, leading to an inability to engage in sexual intimacy with women. Recent acts of mass violence have been linked to self-identified incels, leading to an increased need for awareness of incel worldviews, argot, and demographics among psychiatrists. Limited research exists to describe this heterogenous group, with existing data suggesting higher rates of depression, anxiety, and suicidal ideation within the demographic. This column reviews the incel worldview, existing literature, how to identify an individual with incel beliefs based on vocabulary and internet usage, and treatment modalities.
