Americans' Views on Origins of Homosexuality Remain Split

Most say being gay or lesbian starts at birth


Origins of Homosexuality: Innate or Environmental?




An Increase in the Upbringing and Environment Belief Across Demographics

Though the plurality of Americans believe that being gay is present a birth, there continues to be large differences in perspectives across demographic, religious, and political dimensions. Those with college educations, whites, females, liberals, Democrats, high-income earners, and those who seldom or never attend church are the most likely to believe that being gay or lesbian is something people are born with. Most of these differences among the various demographic groups were evident in previous years, with nonwhites' belief in the upbringing and environment theory substantially higher this year than last year.

Bottom Line

The contention on this question of a person's sexual orientation possibly reflects a lack of input from the scientific community, which historically has not shied away from offering its opinion on lesbian, gay, bisexual, or transgender (LGBT) issues and questions. The American Psychiatric Association removed homosexuality from its manual of mental disorders in 1973, giving credence to the nascent gay rights movement at the time.

U.S. public opinion about gays has changed drastically in recent decades on the issues of marriage equality and LGBT acceptance as a whole, possibly related to the fact that three in four Americans say they have a friend, relative, or coworker who has told them that he or she is gay. Though being gay as the result of genetics or other factors before birth has become a considerably more mainstream belief and is now mentioned by a plurality of Americans, it is still one held by slightly less than half of the U.S. population. This disagreement seems likely to continue as long as the scientific community remains agnostic about the question.
