Our reanalyses found *little* evidence that sexual orientation is associated with 2D:4D ratios after accounting for publication bias. 🧵1/7 osf.io/preprints/ps... 1159
Victor Shiramizu @victorshiramizu.bsky.social · 03/11/2025There’s been a long-standing claim that the ratio between the index and ring fingers (the 2D:4D ratio) reflects prenatal androgen exposure, and that this might relate to sexual orientation. 2/7 110
Victor Shiramizu @victorshiramizu.bsky.social · 03/11/2025Recently, Swift-Gallant et al. (2025) conducted an updated meta-analysis on 2D:4D and sexual orientation, reporting more male-typical digit ratios in same-sex-oriented women and more female-typical ratios in homosexual men compared to heterosexual groups. 3/7 110
