I’m continually amused by just what I have to look up to get a particular story right. Writing fiction, you’re inevitably going to come up with interesting ideas that you want to explore — ideas that would feel flat if you didn’t do your homework.
Sometimes it manifests in weird ways.
For example, I’ve been working on a short story that takes place on an alien world, about someone who finds the remnants of an extinct civilization. I had to laugh when I realized I needed to research what makes ancient Roman concrete so damn good (here was the best link I found, btw) — all so I could write a scene about ancient ruins.
The same story required that I really brush up on Norse mythology, too, and not just the basics like the pantheon. I was thinking about how it was interesting that Norse mythology has so many different worlds and planes of existence, and it made me wonder if that influenced how far and wide they explored (and pillaged, depending on the century). Reading up on the mythology, I came across the concepts of the utangard and the innangard, concepts that really fit my character and the story, helping flesh everything out.
Research takes a lot of time to even take the most cursory of glances. Sometimes hours of research may amount to a few lines in a short story. Other times, the hours of research may not even make it into the story, amounting to little more than helping flesh out character’s background.
It’s all worth it, though, because it’s the little things that can separate a mediocre story from a story that will catch a reader — and there’s no better way to do that than doing your homework as a writer.
