Individuals' beliefs about the etiology of same-sex sexual orientation

We examined the relationships between beliefs about the etiology of having a same-sex sexual orientation, sexual prejudice, and support for gay-relevant legislation using the justification-suppression model of prejudice as our theoretical foundation. Results indicated that more belief that a same-sex sexual orientation was due to nurture factors predicted less support for gay-relevant legislation, and that this relationship was mediated by levels of sexual prejudice. The opposite pattern was found for belief that a same-sex sexual orientation was due to nature factors. This suggests that beliefs about the etiology of sexual orientation may serve as justification (or suppression) factors in the expression of prejudice toward gay men and lesbians.
