The present research examined the hypothesis that heterosexual men's motivation to differentiate their ingroup from gay men moderates the link between egalitarianism and sexual prejudice. In two experiments conducted in Switzerland (N = 74) and Ecuador (N = 104), we assessed heterosexual men's endorsement of egalitarian values and experimentally manipulated scientific evidence supporting or refuting the existence of biological differences between heterosexual and gay men (the biological theory). The main dependent variable was attitude towards homosexuality. As predicted, the interaction between egalitarianism and the biological theory was significant in both experiments, t(67) = 3.18, p = .002, ηp 2 = .13, and t(100) = 2.26, p = .026, ηp 2 = .04, respectively. Egalitarianism increased positive attitudes towards homosexuality only when science supported the existence of biological differences between heterosexual and gay men. We discuss the relevance of this finding to intergroup relations.
异性恋男性将自己的内群体与男同性恋者区分开来的动机，调节了平等主义与性偏见之间的联系。在瑞士进行的两项实验（N = 74）和厄瓜多尔进行的两项实验（N = 104）中，我们评估了异性恋男性对平等主义价值观的认同，并通过实验操纵了支持或反驳异性恋男性与男同性恋者之间存在生物学差异的科学证据（生物学理论）。主要因变量是对同性恋的态度。正如预测的那样，平等主义与生物学理论之间的交互作用在两项实验中均显著，分别为t(67) = 3.18，p = .002，ηp 2 = .13，以及t(100) = 2.26，p = .026，ηp 2 = .04。只有当科学支持异性恋男性与男同性恋者之间存在生物学差异时，平等主义才会增加对同性恋的积极态度。我们讨论了这一发现与群体间关系的相关性。
