The original Turing test was not the most common known one, in which a computer and a human compete to give answers and with just seeing their written responses, a judge judges who is the computer and who is the human, the original Turing test was to distinguish between a man and a woman.
I quote Wikipedia here:
[i]To demonstrate this approach Turing proposes a test inspired by a party game, known as the "Imitation Game," in which a man and a woman go into separate rooms and guests try to tell them apart by writing a series of questions and reading the typewritten answers sent back. In this game both the man and the woman aim to convince the guests that they are the other. (Huma Shah argues that this two-human version of the game was presented by Turing only to introduce the reader to the machine-human question-answer test). Turing described his new version of the game as follows:
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? These questions replace our original, "Can machines think?"[/i]
I think I myself would fail at this Turing test. Besides asking directly "are you a woman" or "what sex organ do you have" (which in the imitation test will surely give a lie as an answer), I wouldn't know what definitely distinguishes a man from a woman. It's not as if, besides biology, there's a hard divide between the two of things only women do.
