Comment on Large-scale GWAS reveals insights into the genetic architecture of same-sex sexual behavior

The phenotypic measures used by Ganna et al. (Research Articles, 30 August 2019, p. 882) lump together predominantly heterosexual, bisexual, and homosexual individuals, including those who have experimented with a same-sex partner only once. This may have resulted in misleading associations to personality traits unrelated to understood categories of human sexuality. Scientific studies of human sexuality should use validated and reliable measures of sexual behaviors, attractions, and identities that capture the full spectrum of complexity.

Mixing individuals with different sexual orientations together in research can lead to misleading associations, and it is important to use validated and reliable measures for studying human sexuality.
