Genetic research on sexual orientation and gender identity generates disproportionate public interest given how little is still known. A study published in 2026 in Behavior Genetics has attempted to answer a key question: what does the population really think about studying the genetic bases of these traits?
The team from the University of Illinois (United States), led by researcher Briana L. Kunstman and with the participation of Andrea M. Woosley and Jaime Derringer, collected the opinions of 338 people through social media. Volunteers had their level of genetic knowledge measured, were asked to estimate the heritability of different traits and to rate their attitude toward genetic research on sexual orientation and gender identity, as well as to explain in their own words the risks and benefits they imagined.
The results, published on February 28, 2026, reveal an ambivalent picture: attitudes fell around the midpoint of the scale. Two associations stood out: the more genetic knowledge a person had, the more negative their attitude tended to be toward this type of research (β = −0.16), and people with minority sexual or gender identities showed more negative attitudes than the rest (β = −0.17).
The authors offer an interesting interpretation of the first finding: those who know more about genetics are also better prepared to anticipate the methodological limitations and risks of these studies, and therefore tend to view them more critically. Recurring themes in the open-ended responses included doubts about the feasibility of high-quality research, concerns about data protection, fear that findings might be used to support preconceived conclusions or screening practices, and the counterpoint of those who point out that demonstrating a biological basis could validate transgender people’s identities as something natural.
The authors recall that this research carries specific risks because of its possible misuse in medical, legal and political contexts. Understanding what the public thinks is key to designing responsible studies, communicating results well and preventing science from fueling prejudice or false determinism. This open-access work offers concrete recommendations for planning and disseminating genetic research on sexual orientation and gender identity.
