Allport's Theory of Interpersonal Contact suggests that coming into contact with a member of an outgroup should increase support for that outgroup. Previous studies find mixed results when applying Allport's theory to reported contact with transgender people. We posit that this is due to imprecise and aggregated measures of contact and a lack of attention to the differences between contact that is ephemeral or ongoing and voluntary or obligatory. We explore our theories with data from a large, high-quality survey conducted in early 2020. We find that while various forms of contact (including voluntary and obligatory) predict warmer ratings on feeling thermometers, only close personal friendships-contact that is voluntary and ongoing-predicts attitudes toward transgender-inclusive policies.
