Chances of passing a Turing Test after a certain number of questions Assuming that; • the computer program is interrogated alongside another human in comparison • the computer program imitates an average human • the other human responds like an average human • the judge is aware that one of the two is a computer program • the computer program loses at the first clearly non-human answer Note that if the responses of the computer program and the other human appear equally human, the maximum chance of any judge guessing wrong is 50%. Supposing there is; % Chance that the program gives a clearly human response % Room for doubt in a judge's mind otherwise
