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.
Arguably unlike the conventional Turing test, this is most interesting when the judges are very familiar with the art of conversation programs, meaning that in the regular Turing test they can very rapidly tell the difference between a computer program and a human acting normally.
As a result, programmers (especially hackers) will sometimes indulge in an informal reverse Turing test for recreation.
Describing such a situation as a "reverse Turing test" typically occurs retroactively.
There are also cases of accidental reverse Turing tests, occurring when a programmer is in a sufficiently non-human mood that his conversation unintentionally resembles that of a computer.
[citation needed] In these cases the description is invariably retroactive and humorously intended.
