Many people speak of making decisions by instinct, or of "gut feelings." Without getting into the conversation of nature versus nurture, human instinct is a peculiar thing, something in which many people place a great amount of faith, but most people don't even fully understand the difference between instinct and intuition. Instinct is something that is fundamental to a creature's biological makeup, while intuition is the result of the brain's complexity leading to the synthesis of a solution without presenting in detail all of the steps it took to reach that result.
Creative writing, or the speculative fiction genre, has long leveraged something called the MICE quotient. I first came across this when I was reading an Orson Scott Card book on how to write science fiction and fantasy (I think it was even titled How to Write Science Fiction and Fantasy). The premise is that stories in the speculative fiction genre can be broadly binned as having one or more of four, primary drivers: milieu, idea, character, and event. Although most good stories will incorporate multiple of these components, with different ones emphasized at different times, there is usually one that drives the story forward.
