No, fictional stories can not tell us something new about human behavior. yes, they can illustrate behavior we already know happens, but we need to be careful not to base any new understanding of human behavior on stories that did not happen. Otherwise, then I guess we can stop studying psychology/sociology/anthropology/etc. and instead resort to making up stories all day to fill in what we do not know.
