Why is "Theory of humor" trending?

Wikipedia Overview

Although humor is a phenomenon experienced by most humans, its exact nature is a topic of heavy debate. There are many theories of humor which attempt to explain what it is, what social functions it serves, and what would be considered humorous. Although various classical theories of humor and laughter may be found, in contemporary academic literature, three theories of humor appear repeatedly: relief theory, superiority theory, and incongruity theory. Among current humor researchers, there is yet no perfect consensus about which of these three theories of humor is most valid, though the incongruity theory is the most predominant. Some proponents of each of these most commonly known theories originally claimed that theirs and theirs alone explained all humor. There is, however, consensus that these theories, especially incongruity, have been building blocks for some later ones. Many theorists also now hold that the three main theories are of narrower focus than originally intended, and that there are examples of humor where various theories explain different aspects. Similarly, one view holds that theories have a combinative effect; Jeroen Vandaele claims that incongruity and superiority theories describe complementary mechanisms that together create humor. Another such combinative view involves incongruity and relief, that Terry Eagleton considers in his 2019 book, Humour.
