Objective. Past research reveals how religion and opinions about the cause of homosexuality influence attitudes concerning same-sex unions. No study to date contains a comprehensive collection of religion measures while also accounting for views of the cause of homosexuality. Therefore, this study investigates the extent to which religion predicts certain attribution beliefs as well as attitudes toward same-sex unions while controlling for attribution beliefs.
Method. The Baylor Religion Survey (2007) is used to estimate binary logistic models predicting the effects of religion and attribution beliefs on attitudes toward same-sex unions.
Findings. First, religion is strongly associated with the belief that homosexuals choose their sexual orientation. Second, religion maintains a significant association with attitudes toward same-sex unions despite inclusion of an attribution variable.
Conclusion. Even if a biological explanation for homosexuality is ultimately proven, unfavorable attitudes toward same-sex unions will most likely endure due to religion's persistent effect.
