Attitude change in response to information that male homosexuality has a biological basis

We assessed 28 college students' attitudes toward homosexuals immediately b efore and 1 week after the presentation of either an article suggesting tha t male homosexuality has a biological component or a control article, Chang e in attitude toward homosexuality for subjects exposed to the biological a rticle depended on subjects' memory of the article and on their college maj or. Subjects undecided in their major and those who scored below average on a memory test of the article's content had the most positive attitude chan ge, while biological science majors and those who scored above average on t he memory test became more negative toward homosexuals. The results suggest biological information about homosexuality can have both beneficial and de trimental effects on attitudes toward homosexuals.
