Not quite over the rainbow: the unrelenting and insidious nature of heteronormative ideology

Heteronormative ideology refers to the belief that there are two separate and opposing genders with associated natural roles that match their assigned sex, and that heterosexuality is a given. It is pervasive and persistent, carrying negative consequences. Because it is embedded in societal institutions and propagated through socialization and other widely held ideologies, it is prevalent among both cis-hetero and LGBTQI+ individuals. In the current article, we discuss the unrelenting and insidious nature of heteronormative ideology, review some of the social-psychological mechanisms that contribute to its maintenance, and provide directions for future research that could inform efforts to combat it. We argue that threat reactions to non-heteronormative behavior reinforce heteronormative beliefs and that interventions are needed to address both prejudice and its underlying mechanisms.
