捕获22。任何想摆脱战斗职责的人都不会真的疯狂。只有一个渔获量，那是捕获22，它指出，面对现实和直接的危险，人们对自己的安全是一个理性思想的过程。奥尔很疯狂，可能被扎根。他要做的就是问。一旦他这样做，他将不再疯狂，不得不执行更多的任务。如果他不这样做，奥尔会疯狂地驾驶更多的任务和理智，但是如果他理智，他就必须驾驶它们。如果他飞了他们，他就疯了，不必这样做。但是，如果他不想让他理智，就必须这样做。
(Catch-22. Anyone who wants to get out of combat duty isn't really crazy. There was only one catch and that was Catch-22, which specified that a concern for one's own safety in the face of dangers that were real and immediate was the process of a rational mind. Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn't, but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to.)
约瑟夫·海勒（Joseph Heller）在《捕获22》中说明了一个悖论的概念，该悖论使个人在矛盾的情况下，就其理智和义务困扰。角色ORR体现了这一困境。该法规本质上坚持认为，士兵必须表现出缺乏对自己的安全性的关注，因为他们被认为是疯狂而不适合战斗的。但是，当人们认识到危险并寻求救济的那一刻，它们被认为是理智的，必须继续参加危险的任务。
这创造了一个荒谬的循环，避免危险的愿望等同于理智，但承认欲望阻止了一个人逃避飞行任务的危险。海勒（Heller）对这种捕捉的描绘封装了战争的不合逻辑和官僚性，反映了人类推理的更广泛的复杂性以及被困在如此站不住下的情况下所面临的系统性挑战。
