The Turing test is a test of a computer’s ability to exhibit intelligent behavior, usually in the form of a natural language conversation between a judge, another person, and a computer designed to mimic a human. If the judge can’t tell the difference between the second person and the computer, it has passed the Turing test. In the hilarious TV cartoon Futurama, they joked of a reverse Turing test to figure out if a robot was really a robot.
