There are several different ways that scientists have developed to help "test" the effectiveness or how realistic Artificial Intelligence really is. One of the more well-known tests, developed by Alan Turing, called the "Turing Test," states that "...if a machine acts as intelligently as a human being, then it is as intelligent as a human being." A test subject communicates with something, and if the individual is unable to correctly determine whether or not he or she is communicating with a person or a machine, then the machine effectively passes the Turing Test.
There are several other evaluative measures used in reference to Artificial Intelligence. A conventional system for describing the apparent effectiveness of Artificial Intelligence have been developed. The following terms describe the varying levels of how artificially intelligent machines compare to humans:
