Abstract
To support the LGBTQ+ community, many straight, cisgender individuals position themselves as allies to their cause. It is possible that those identifying as liberal may champion LGBTQ+ causes more passionately than those identifying as conservative, though it is also possible that liberals’ self-perceptions do not align with how LGBTQ+ individuals perceive them. In this study, we systematically investigated the relationship between political orientation and allyship to the LGBTQ+ community. We recruited 378 dyads composed of a cisgender, straight individual and an LGBTQ+ close other. Findings suggested that self-perceptions of allyship (from cisgender, straight individuals) were largely consistent with evaluations from LGBTQ+ close others. In line with our expectations, on average, liberals (compared to conservatives) both viewed themselves and were perceived as better allies. However, there was a small but significant tendency for liberals to overestimate their allyship relative to conservatives. In addition, exploratory analyses revealed other-perceived allyship was positively associated with higher interpersonal trust, underscoring allyship’s importance in close relationships. These findings contribute to a growing understanding of the ideological and interpersonal antecedents of allyship and inform strategies for fostering stronger, more authentic relationships with the LGBTQ+ community.
