An algorithm deduced the sexuality of people on a dating site with up to 91% accuracy, raising tricky ethical questions
Now, does the paper show that the AI can guess your sexuality from a photograph with 91% accuracy? Nope.
As the paper states:
The AUC = .91 does not imply that 91% of gay men in a given population can be identified, or that the classification results are correct 91% of the time.
Here’s the 91% claim. The AI is shown five photos from two individuals on the dating website. Based on what it has learned from other photos, it offers a guess as to which is more likely to be gay. In 91% of the cases where there is a gay man and a straight man being compared it guesses correctly. Accurate headline:
AI can distinguish gay men based on five dating profile pics 91% of the time.
When presented with just one pair of images of men, the AI guessed right 81% of the time. Human judges—recruited by Mechanical Turk and untrained on any images—guessed right just 61% of the time. For women, both were right less often: 71% for the AI and 54% for the humans. In this test, 50% is rock bottom, the equivalent of zero gaydar.)
