Traditional stories, or stories about traditions, differ from both fiction and nonfiction in that the importance of transmitting the story's worldview is generally understood to transcend an immediate need to establish its categorization as imaginary or factual. In the academic circles of literature, religion, history, and anthropology, categories of traditional story are important terminology to identify and interpret stories more precisely. Some stories belong in multiple categories and some stories do not fit into any category.
An anecdote is a short and amusing or interesting story about a biographical incident. It may be as brief as the setting and provocation of a bon mot. An anecdote is always presented as based on a real incident involving actual persons, whether famous or not, usually in an identifiable place; whether authentic or not, it has verisimilitude or truthiness. Over time, modification in reuse may convert a particular anecdote to a fictional piece, one that is retold but is "too good to be true". Sometimes humorous, anecdotes are not jokes, because their primary purpose is not simply to evoke laughter, but to reveal a truth more general than the brief tale itself, or to delineate an institutional or character trait in such a light that it strikes in a flash of insight to the very essence. Novalis observed, "An anecdote is a historical element — a historical molecule or epigram." A brief monologue beginning "A man pops in a bar ..." will be a joke. A brief monologue beginning "Once J. Edgar Hoover popped in a bar ..." will be an anecdote. An anecdote thus is closer to the tradition of the parable than the patently invented fable with its animal characters and generic human figures — but it is distinct from the parable in the historical specificity which it claims.
