Societal beliefs about various aspects of sexual orientation have been shown to influence whether people have discriminatory or supportive attitudes toward diverse sexual orientations. The overall aim of this study is to measure the beliefs about sexual orientation among a diverse sample of university students from two institutions in Canada and the United States of America. Specifically, we explored how beliefs varied among individuals with differing sexual orientations and gender identities, while controlling for cultural differences. A total of 475 participants completed an online survey comprising of the Sexual Orientations Beliefs Scale (SOBS). ANCOVAs revealed that sexual orientation was a significant factor for all four subscales of the SOBS (naturalness, homogeneity, informativeness, and discreteness). Sexual orientation was the most significant predictor of endorsing different sexual orientation beliefs. We found a significant interaction between gender and sexual orientation, revealing that perceptions of sexual orientation differ between straight-identified men and straight women.
