- Deep Neural Networks can detect sexual orientation from faces
Deep Neural Networks (DNN) can detect sexual orientation from faces
This study by Yilun Wang and Michael Kosinski claims to show that faces contain information about sexual orientation and that AI can interpreted this better than humans.
“Given a single facial image, a classifier could correctly distinguish between gay an heterosexual men in 81% of cases, and in 71% of cases for women. Human judges achieved much lower accuracy: 61% for men and 54 % for women. The accuracy of the algorithm increased to 91% and 83%, respectively, give five facial images per person. Facial features employed by the classifier included both fixed (e.g., nose shape) and transient facial features (e.g., grooming style). Consistent with the prenatal hormone theory of sexual orientation, gay men and women tended to have gender-atypical facial morphology, expressions and grooming styles.”

What's at stake?
As companies and governments are increasingly using computer vision algorithms to detect people’s intimate traits, their findings expose a threat to the privacy and safety of gay men and women.

But: proof that shows otherwise: Three catagories:
- Character can influence one's facial appearance: Lohmus, M., Sunstrom, L.f., and Bjorklund, M. (2009). Dress for succes: Human Facial expressions are important signals of emotions. Annales Zoologici Fennici, 56 (1), 75-80, http://doi.org/10.5735/086.046.0108
- facial appearance can alter one's character
- there is broad range of factors affecting both facial appearance and one's traits. Those include pre- and post-natal hormonal levels, developmental history, enverionmental factors, and gene expression. Testosterone levels, for instance, significantly affect both: behavior and facial appearance.
