Reverse Turing test a computer is then said to "pass the Turing test" if it is also judged human. Any of these roles may be changed to form a "reverse Turing test". Arguably the standard form of the reverse Turing test is one in which the subjects attempt to appear to be a computer rather than a human. A formal reverse Turing test follows the same format as a Turing test. Human subjects attempt to imitate the conversational style of a conversation program such as ELIZA. Doing this well involves deliberately ignoring, to some degree, the meaning of the conversation that is immediately
Turing test list of mechanical rules, without thinking or having a mind at all. John Searle has argued that external behaviour cannot be used to determine if a machine is "actually" thinking or merely "simulating thinking." His Chinese room argument is intended to show that, even if the Turing test is a good operational definition of intelligence, it may not indicate that the machine has a mind, consciousness, or intentionality. (Intentionality is a philosophical term for the power of thoughts to be "about" something.) Turing anticipated this line of criticism in his original paper, writing: In practice, the test's results can easily
