They really pushed its buttons. Researchers at MIT exposed an artificial intelligence program — named Norman after the character in Psycho — to violent and gruesome images from an unidentified Reddit message board, then gave it Rorschach ink blot tests. Where a normal algorithm saw a vase with flowers, Norman saw a man being shot. A group of birds on a tree branch became a man electrocuted to death. The researchers say the experiment serves as a warning about the dangers of using biased data when helping machines to learn.
