No, check out the study I linked. They controlled for race, gender, etc. And human guessing was just 55 percent accurate versus 72 percent for the ML model.

- mattkrause 5y agoSure, but look at what cues their system uses: "The highest predictive power was afforded by head orientation (58%), followed by emotional expression (57%). Liberals tended to face the camera more directly, were more likely to express surprise, and less likely to express disgust. " The system isn't telling you anything about the person themselves; it's picking up on artifacts about how different subcultures present themselves in a public profile.
- fighterpilot 5y agoIt's your speculation that the underlying reason these features work is because individuals are adopting the behavioral norms of a subculture. This may or may not be the case. Also, some dimensions of personality are correlated with political belief, so even if these features weren't useful beyond predicting political belief (which itself is an unsubstantiated/speculative claim), there should still be some transitive predictive utility there.
