Science, Sexuality, and Civil Rights: Does Information on the Causes of Sexual Orientation Change Attitudes?

Does learning that homosexuality is innate increase support for gay rights? Because there is a strong correlation between the belief that people are “born gay” and support for gay rights, many assume the former causes the latter. However, correlation does not equal causation. Drawing on data from a US-representative experiment, we examine whether exposure to scientific information on the origins of sexual orientation influences attitudes toward gay people and support for gay rights. The information influenced participants’ beliefs about the causes of homosexuality but had no impact on their attitudes. Further, belief change was contingent on ideology—liberals were more persuaded by information that people are born gay, and conservatives by information that people are not born gay. In the contemporary context, shifting causal attributions may not lead to attitude updating; rather, broad political values may act as a cognitive filter, biasing the uptake of new information about sexual orientation.
