Fiction writers frequently ask questions about "believability" - whether their plot, characters and devices go too far doing the rather incredible things that go along with SFF. I think a related but slightly different question we should stop and ask ourselves now and then is if what we are reading/writing is real or fake - a much more binary question that can't be rationalized away by reference to other parts of the text.
Most of the time, if I stop reading a book the reason I stop has a lot to do with whether the people and world seems real or not. Which is not to say ordinary or familiar. It is usually more like "Given the way this SFF world works and this character's background, do they seem to be acting like a real person would?" OR "Given the technology and economy of this world, does it make sense that the majority of people are peasant farmers, or that a villainous queen can control everything?"
The danger of SFF is that it is a top down approach of supposing something speculative and then fitting the ordinary into it. In so doing, our individual units of believability - human characters - can become so distorted by the demands and strictures of fitting into this synthetic universe that they no longer bear much resemblance to real people. This may happen on an individual scale with a hero whose motivations and fears don't balance out right, or to a society whose economy or institutions don't take into account the amount of magic or robots or whatever that are implicit to the story.
