Alice W. Flaherty said this quote
“ Above all, readers want useful information, whether from a road sign or an investment guide. This motive is not completely absent even in readers of fiction, although few people read Madame Bovary for straightforward advice on how not to run a marriage. At a more abstract level, readers want a narrative that makes the world seem to make sense, and they sometimes choose stories that fit with their worldview rather than stories that fit the facts. ”
