 The core meaning of “incongruity” in various versions of the Incongruity Theory, then, is that some thing or event we perceive or think about violates our standard mental patterns and normal expectations. (If we are listening to a joke for the second time, of course, there is a sense in which we expect the incongruous punch line, but it still violates our ordinary expectations.) Beyond that core meaning, various thinkers have added different details, many of which are incompatible with each other. In contemporary psychology, for example, theorists such as Thomas Schultz (1976) and Jerry Suls (1972, 1983) have claimed that what we enjoy in humor is not incongruity itself, but the resolution of incongruity. After age seven, Schultz says, we require the fitting of the apparently anomalous element into some conceptual schema. That is what happens when we “get” a joke. Indeed, Schultz does not even call unresolvable incongruity “humor”—he calls it “nonsense.” The examples of humor cited by these theorists are typically jokes in which the punch line is momentarily confusing, but then the hearer reinterprets the first part so that it makes a kind of sense. When, for instance, Mae West said, “Marriage is a great institution, but I’m not ready for an institution,” the shift in meanings of “institution” is the incongruity, but it takes a moment to follow that shift, and the pleasure is in figuring out that the word has two meanings. Amusement, according to this understanding of humor, is akin to puzzle-solving. Other theorists insist that incongruity-resolution figures in only some humor, and that the pleasure of amusement is not like puzzle-solving.
