Catch 22

A catch-22 is a paradoxical situation from which an individual cannot escape because of contradictory rules. For example: To apply for this job, you would have to be insane; but if you are insane, you are unacceptable for the job. Catch-22s often result from rules, regulations, or procedures that an individual is subject to but has no control over because to fight the rule is to accept it. Another example is a situation in which someone is in need of something that can only be had by not being in need of it. One connotation of the term is that the creators of the "catch-22" have created arbitrary rules in order to justify and conceal their own abuse of power.

The archetypal catch-22, as formulated by Heller, involves the case of John Yossarian, a U.S. Army Air Forces bombardier, who wishes to be grounded from combat flight. This will only happen if he is evaluated by the squadron's flight surgeon and found "unfit to fly". "Unfit" would be any pilot who is willing to fly such dangerous missions, as one would have to be mad to volunteer for possible death. However, to be evaluated, he must request the evaluation, an act that is considered sufficient proof for being declared sane. These conditions make it impossible to be declared "unfit".

The "Catch-22" is that "anyone who wants to get out of combat duty isn't really crazy". Hence, pilots who request a mental fitness evaluation are sane, and therefore must fly in combat. At the same time, if an evaluation is not requested by the pilot, he will never receive one and thus can never be found insane, meaning he must also fly in combat.

Therefore, Catch-22 ensures that no pilot can ever be grounded for being insane even if he is.
