Lesbian, gay and bisexual (LGB) people are supposed to be better at gaydar than heterosexual. Across two studies we examined auditory gaydar performed by LGB and heterosexual listeners. In Study 1 participants (n = 127) listened to male and female speakers (n = 10) and judged their sexual orientation on a binary choice (gay/lesbian vs. heterosexual). In Study 2, participants (n = 192) judged speakers' (n = 31) sexual orientation on a Kinsey-like scale (1 = exclusively heterosexual, 7 = exclusively gay/lesbian). Results showed gaydar judgments differences in relative terms that did not indicate an overall gaydar accuracy. Moreover, LGB participants were not better at gaydar than heterosexual participants but rather showed a shift in criterion when making auditory gaydar judgments, namely they report a weaker straight categorization bias. Overall, these findings contribute to the understanding of sexual orientation categorization among heterosexual majority and LGB minority groups.
