Nothing can be further from the truth.
We are concerned with the story and its traditions, the occasions the stories are told, who tells the stories, and why, and much more. An exmaple would be the comparing of older fairy lore with current UFO stories. When discussing the folklore of UFOs, folklorists talk about the similarites, as well as the differences, in the types of UFO stories that are told all over the world. Conspiracy theories, animal behavoir and imagery, abduction tales, the role of popular culture, telepathic communications, and more, are all part of the lore that is examined by folklorists. It may be true, it may not be true.
