Researchers say they can train computers to identify sexual orientation and criminality by scanning a person’s face. But to critics it’s just plain bad science. – On the first day of school, a child looks into a digital camera linked to the school’s computer. Upon a quick scan, the machine reports that the child’s facial contours indicate a likelihood toward aggression, and she is tagged for extra supervision. Not far away, another artificial intelligence screening system scans a man’s face. It deduces from his brow shape that he is likely to be introverted, and he is rejected for a sales job. Plastic surgeons, meanwhile, find themselves overwhelmed with requests for a “perfect” face that doesn’t show any “bad” traits.
