 Turing (1950) introduces the imitation game by describing a game in which the participants are a man, a woman, and a human interrogator. The interrogator is in a room apart from the other two, and is set the task of determining which of the other two is a man and which is a woman. Both the man and the woman are set the task of trying to convince the interrogator that they are the woman. Turing recommends that the best strategy for the woman is to answer all questions truthfully; of course, the best strategy for the man will require some lying. The participants in this game also use teletypewriter to communicate with one another—to avoid clues that might be offered by tone of voice, etc. Turing then says: “We now ask the question, ‘What will happen when a machine takes the part of A in this game?’ Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman?” (434).
