To be fairer, most writers do not agressively fact-check. It's time-consuming. Often a "bible" exists that explains the most important concepts and events. Everything else is made up on the spot. Which doesn't have to be a bad thing, e.g. Lost was a critically acclaimed and much loved series, even though the writers had no clue where it was going. They just wrote episode after episode.

After all, a Fan only sees the finished product. But writers think of easily 3 alternatives per story point, and that expontenially grows as the series grows. Things are easily mixed and forgotten. Putting it all on paper would be almost a daily job.
