A Catch-22 is a situation in which paradoxical rules make a desired outcome impossible to achieve. It comes from Joseph Heller’s 1961 World War II novel, Catch-22, in which a bomber pilot wishes to get out of flying missions by claiming to be insane, but cannot do so because asking not to fly more missions would be a sign that he is sane. In the book, the bureaucratic clause behind this logic is Catch-22.
Most publications capitalize the C and hyphenate Catch-22. This is safest, as it follows the novel’s title and the way Heller uses the term throughout his book. There are a few common variations, though—including catch-22, catch 22, and Catch 22. Whichever one you use, it doesn’t need to be in quotation marks.
