Here is a convention up for debate, one in the process of becoming visible: in an essay on the pathetic fallacy, author Charles Baxter argues that setting in literary realist fiction should less often reflect the protagonist’s inner state. Baxter has seen too much rain when the hero is sad, too many sad barns when the hero has lost a child (as in the famous John Gardner prompt). In reality, rain is not contingent on emotion and objects do not change their appearances to fit people’s moods. (The Gardner prompt, to describe a barn from the perspective of a grieving father, is more about what a person in a certain mood would notice—but the point holds.) Baxter thinks realism should do more to resist story conventions and accurately represent reality.
Yet on screen, the pathetic fallacy seems widely accepted (especially if there is no voiceover to provide a character’s thoughts), and student fiction seems more and more influenced by film expectations than prose expectations.
