The popular reduction of humor theories into three groups -- Incongruity, Relief, and Superiority theories -- is an over simplification. Several scholars have identified over 100 types of humor theories, and Patricia Keith-Spiegel's classification of humor theories into 8 major types (biological, superiority, incongruity, surprise, ambivalence, release, configuration, and psychoanalytic theories) has been fairly influential. Jim Lyttle suggests that, based on the question they are primarily addressing humor, theories can be classified into 3 different groups. He argues that, depending on their focus, humor theories can be grouped under these categories: functional, stimuli, and response theories. (1) Functional theories of humor ask what purpose humor has in human life. (2) Stimuli theories ask what makes a particular thing funny. (3) Response theorists ask why we find things funny. A better way to phrase this concern is to say that response theorists ask what is particular about feelings of humor.
Thomas Hobbes developed the most well known version of the Superiority theory. Giving emphatic expression to the idea, Hobbes says "that the passion of laughter is nothing else but sudden glory arising from some sudden conception of some eminency in ourselves, by comparison with the infirmity of others, or with our own formerly" (Human Nature, ch. 8). Motivated by the literary conceit of the laugh of triumph, Hobbes's expression the superiority theory looks like more of a theory of laughter than a theory of humor. Baudelaire offers an interesting variation on Hobbes' superiority theory, mixing it with mortal inferiority. He argues that that "laughter is satanic" -- an expression of dominance over animals and a frustrated complaint against our being merely mortal.
Critically reversing the superiority theory, Robert Solomon offers an "inferiority theory" of humor. He thinks that self-recognition in the silly antics and self-deprecating behavior of the Three Stooges is characteristic of a source of humor based in inferiority or modesty....
