The current investigation, following Bobrow and Bailey (2001), aimed to test the kin selection theory of homosexuality in human males using a survey design. A total of 60 heterosexual and 60 homosexual men from England completed items measuring psychological and behavioral indices of “special design” as predicted by adaptation due to kin selection. There were no significant differences between heterosexual and homosexual men in general familial affinity, generous feelings (willingness to provide financial and emotional resources), and benevolent tendencies (such as willingness to baby-sit). These remained non-significant after co-varying for level of personal income (higher among homosexual men), psychological gender, and interest in children. Overall, little support was found for the kin selection theory in a community sample.
