In a fascinating project, researchers at University of California San Diego and the University of Toronto have found that computers are far better than humans at recognizing the difference between real and fake pain in the faces of test subjects. In fact, while humans could tell the difference 55 percent of the time, robots could tell it 85 percent of the time.
“In highly social species such as humans, faces have evolved to convey rich information, including expressions of emotion and pain,” said Kang Lee, a senior author. “And, because of the way our brains are built, people can simulate emotions they’re not actually experiencing – so successfully that they fool other people.
