Investigations of prejudice toward lesbians and gay men mostly rely on self-report questionnaires and rarely make use of indirect, behavioral measures. This field experiment investigated helping in an everyday face-to-face situation as an indicator of discrimination. Members of the public (N = 240) were approached by a person asking for 10 pence for a parking meter. The requestor wore either a neutral or a pro-gay T-shirt. Additional independent variables were the requestor’s and the target person’s gender. Results showed that a person perceived as being a lesbian or a gay man received much less help, especially from men, than the same person perceived as being heterosexual. Findings are discussed in comparison with earlier studies involving either behavioral or self-report measures.
