On the Origin of Beliefs about the Sexual Orientation and Gender-role Development of Children Raised by Gay-male and Heterosexual Parents: An Italian Study

In three studies, heterosexual participants were presented with descriptions of heterosexual and gay-male parents. Importantly, the level of gender-role conformity of the gay-male parents was experimentally manipulated, resulting in their level of gender-role conformity ranging from high to low. Compared to the son of a heterosexual couple, the son of all gay-male couples had a lower expected likelihood of developing as heterosexual. This result was independent of the level of gender-role conformity of the gay-male couples (study 1–3). The beliefs about the gender-role development of the son, in terms of anticipated masculinity (study 1), gender stereotyping (study 2), and affective adjustment (study 3), mapped onto the level of gender-role conformity of the parents, regardless of their sexual orientation. Also, heterosexual parents were consistently judged more positively than gay-male parents, independently of their level of gender-role conformity (study 1–3).
