The Authors draw on cognitive sociology and attribution theory to infer whether people classify homosexuality as an identity or a behavior. Using six waves of World Values Survey data covering 85 countries, the authors conduct factor and multilevel regression analyses to examine patterns of intolerance toward gay people alongside racialized groups, immigrants, and users of alcohol or illicit substances, in the context of who constitutes an undesirable neighbor. The authors examine changes in these patterns over time and variation across broad cultural zones. Evaluations of homosexuality tend to cluster with alcohol and substance use in non-Western societies, albeit less strongly over time, but with race and nativity among Western and Latin American publics. The authors suggest that homosexuality is widely perceived as an identity in Western and “West-adjacent” countries, whereas elsewhere it is more often understood in behavioral terms. Over time, homosexuality is increasingly interpreted as an identity trait rather than a deviant behavior.
