One of the hardest lessons for science fiction and fantasy writers is learning to trust the reader.
You've invented this incredible world. You understand its complexities and nuances — the political systems, the magical rules, the technological constraints, the three-thousand-year history. And you want to make sure readers understand them too.
So you explain. And explain. And explain some more.
Stop.
Readers are smart
Most people reading SFF have read a lot of it. They know how to pick up on world details from context. They don't need everything spelled out.
The sense of discovery, of piecing together how your world works, is part of the pleasure of reading SFF. When you explain everything, you rob readers of that pleasure. You turn exploration into a lecture.
The iceberg principle
Ernest Hemingway described the iceberg theory of writing: what appears on the page should be a fraction of what the writer knows. The dignity of an iceberg comes from the mass beneath the surface.
This applies especially well to SFF. Know ten times more than you show. Build your world thoroughly — understand its history and politics and ecology — but then be ruthless about what actually appears in the prose.
Include only what the story needs. Everything else remains beneath the surface, giving depth and weight to what's visible. Readers will sense that depth even if they never see it directly.
The practical test
When in doubt, cut the explanation and see if the passage still makes sense.
Often it does. And it's stronger for it.
“The Binding won't hold much longer,” tells us something is magically contained and failing, even if we don't know exactly what the Binding is. We'll learn. The urgency comes through.
You don't need to explain everything before it becomes relevant. You can trust readers to hold uncertainty, to keep reading, to piece things together. That's part of what they came for.
The trap
New writers often dump world building on the page because they want readers to appreciate all the work they've done. But readers don't come for the encyclopedia entries. They come for story.
World building is the setting in which story occurs, not a substitute for it.
Your invented history is fascinating — to you. But the reader wants to know what happens next, not what happened three thousand years ago. Give them just enough context to understand the current stakes, and save the history lecture for your world building notes.
The Silly Shirt Manifesto covers world building in depth — including Sanderson's laws of magic, the difference between hard and soft systems, and how to ground the fantastic in the familiar.
