Are people born gay? Show more Show less
Back to question

Few scientific questions generate as much intrigue and political turmoil as the origins of sexual orientation. Is there a clear genetic or hormonal link to sexual orientation that indicates gay people are, in the words of Lady Gaga, "Born This Way"? Can we ever know if same-sex attraction is determined before birth? Is this a question that should even be asked?

No, people are not born gay Show more Show less

To reduce sexual orientation to genetics or hormones reduces it to a binary outcome. Sexuality is not binary, it is fluid and no genetic explanation has been able to accomodate this.

Sexual orientation is not a binary outcome

Only things with binary outcomes can be reduced to genetics. Sexual orientation is not binary, it is fluid.

With binary outcomes, it is possible to say with certainty that a foetus, if brought to term, will be born with a gene that will affect its development or behaviour. With non-binary outcomes, it is not possible. Sexual orientation is not a binary outcome and is therefore not something that is dictated before birth.

The Argument

Medical professionals can test the genetics of two embryos and tell expectant parents with 100% certainty that their babies will be identical twins. Being a twin is a binary outcome. However, when it comes to testing for qualities without a binary answer, things become more difficult. For example, we cannot test the genetics of a child and immediately determine how tall that child will be. Height is a non-binary outcome and depends on the interaction of different genes, childhood nutrition, illness, and environmental impacts. Same-sex attraction is not a binary outcome. Homosexuality is a sliding scale and is, like someone’s height, not something predetermined before we are born.

Counter arguments


[P1] Only binary outcomes are predetermined before birth. [P2] Sexual orientation is not a binary outcome. [P3] Therefore, people are not born gay.
