Hard to answer according to your scheme. There are some things I like to be very realistic about. I base my geography on real-world geography, and try to make social structure, politics, economics et al plausible (although not based on a particular historic time and place). On the other hand, I do incorporate a lot of "mythic realism", meaning that what people have commonly believed, is actually true. The gods are much like the gods of various real-world pantheons except that they actually exist. (To avoid getting into forbidden subject matter, those who believe in one or more gods should feel free to interpret that last comment as referring to everyone else's gods.) The sun really does move across the sky from east to west every day on the path prescribed by the appropriate god(s), and there are similar mythological explanations for climate variation.
