# Iceberg theory > Ernest Hemingway's principle of writing by omission: leave the most important material unstated, know it fully yourself, and let the visible details carry it so the reader feels what lies beneath. Also known as theory of omission ## In practice The iceberg theory, also called the theory of omission, is Ernest Hemingway's idea that a writer can leave out much of what a story is about, as long as the writer knows it, and the reader will still feel it. Only the tip of the iceberg shows on the page; the rest, the history, the motive, the grief, stays underwater and gives the visible part its weight. The idea is close to subtext, and it suits screenwriting. Films show behavior and let audiences infer thought, so a scene in which characters talk around the thing that matters is often stronger than one in which they say it. Hemingway's short story Hills Like White Elephants is the classic example: a couple discuss an operation without ever naming it. The key condition is that the omission is deliberate. Hemingway argued that leaving out what you know strengthens a story, while leaving out what you do not know only leaves holes. A writer using the technique needs to know the hidden material in detail, and needs to plant enough on the surface that the reader can sense its shape. ## A scene that keeps the real subject underwater **A father and daughter clear a dead man's garage** ``` INT. GARAGE - DAY Boxes. A workbench. FRANK (70s) and his daughter LIZ (40s) sort tools into piles: keep, give away. Liz holds up a child-sized fishing rod. Frank looks at it a long moment. FRANK Give that away. Somebody'll use it. LIZ He'd want it to go to a kid. FRANK That's what I said. Liz sets the rod by the door. Frank goes back to the screwdrivers, sorting them by size, then sorting them again. ``` Nobody says whose garage this is, who he was or what happened to him. The child's rod, the pause and the screwdrivers sorted twice carry it. The writer has to know the dead man's story for those details to land; the audience only needs to feel it under the surface. ## What the iceberg theory is The iceberg theory is a principle of writing by omission. The writer leaves the most important material implicit, trusting that the visible details will let the reader sense what is underneath. It is associated above all with Ernest Hemingway, whose spare prose and understated dialogue made it famous in the 1920s and 1930s. Hemingway stated it in Death in the Afternoon (1932), his book about bullfighting. If a writer knows enough about what he is writing, he said, he may omit things he knows, and the reader, if the writing is true enough, will have a feeling of those things as strongly as if they had been stated. He compared it to an iceberg, whose dignity of movement is due to only one-eighth of it being above water. In a later interview with The Paris Review, Hemingway added that anything you know you can eliminate, and it only strengthens your iceberg. The corollary matters as much as the principle: a writer who omits something because he does not know it leaves a hole, not an iceberg. ## Iceberg theory examples In Hills Like White Elephants (1927), an American man and a young woman wait for a train in Spain. They talk about drinks, the landscape and a simple operation he says is perfectly natural. The word abortion never appears, and the story never says what she decides, yet the tension of the conversation tells readers almost everything. Big Two-Hearted River (1925) follows Nick Adams on a solitary fishing trip, describing his camp and his fishing in close detail. The war is barely mentioned, but readers have long read the careful routine as a man holding himself together after it. Hemingway later said the story was about coming back from the war, with the war left out. The approach spread far beyond Hemingway. Raymond Carver's stripped-down stories, much of Harold Pinter's drama and many films built on silences, such as Lost in Translation or Manchester by the Sea, rely on the audience filling in grief, desire or history that the characters never state outright. ## Iceberg theory vs. subtext Subtext is the meaning beneath what characters say and do: the anger under a polite question, the love under an argument. The iceberg theory is a method of producing it on a large scale, by keeping whole parts of the story, a backstory, a trauma, a relationship, off the page while letting them shape everything that appears. Put simply, subtext can be local to a line or a scene, while the iceberg theory is a decision about the whole work. A scene can have subtext in a story that otherwise explains itself fully. A story built on the iceberg principle keeps its central matter underwater from start to finish. The iceberg theory is also related to show, don't tell, but it goes further. Showing replaces a stated emotion with a visible action. Omission removes the cause of the emotion from the page altogether and trusts the reader to sense it from the actions alone. ## Why the iceberg theory works Readers and audiences engage more when they have work to do. Inferring a character's history from small details makes the audience an active participant, and conclusions people reach themselves tend to feel truer than ones they are told. Omission also matches how people actually talk. Few people announce their deepest feelings in conversation; they deflect, joke, change the subject or fix something. Dialogue that circles the real subject sounds more like life, and the strain of not saying it creates tension in itself. Finally, the hidden part gives the surface weight. Details chosen by a writer who knows the whole story carry a precision that random detail does not. The child-sized fishing rod in the excerpt above matters because the writer knows exactly whose it was. ## How to use the iceberg theory Know the underwater part in detail. Write out the backstory, the secret or the loss for yourself, even if none of it reaches the page. The more precisely you know it, the better your choice of the few details that point to it. Choose surface details that point down. An object, a gesture, a repeated action or a sudden silence can carry what is not said. Look for details that only make full sense if the hidden material is true, and cut the ones that would make sense in any story. Test that the audience can feel it. The risk of omission is confusion rather than resonance. Give drafts to readers who do not know the hidden story, and ask what they think is going on underneath. If no one senses it, plant one more clue, without stating it. ## Official sources & context Sources reviewed Oct 30, 2026 - [Wikipedia — Iceberg theory](https://en.wikipedia.org/wiki/Iceberg_theory) ## Common questions ### What is the iceberg theory? The iceberg theory is Ernest Hemingway's principle that a writer can omit much of a story's meaning, as long as the writer knows it, and the reader will still feel it. Only the tip shows on the page. ### Why is it called the iceberg theory? Hemingway compared a story to an iceberg, which moves with dignity because only one-eighth of it is above water. The visible text is the small part; the larger, unstated part gives it weight. ### Where did Hemingway describe the iceberg theory? In Death in the Afternoon (1932), his nonfiction book about bullfighting. He returned to the idea in later interviews, including one with The Paris Review. ### What is an example of the iceberg theory? Hemingway's Hills Like White Elephants, in which a couple discuss an operation without ever naming it as an abortion. Big Two-Hearted River, which barely mentions the war that shapes it, is another. ### What is the theory of omission? The theory of omission is another name for the iceberg theory: the idea that deliberately leaving out known material can make a story stronger, because the reader feels what is missing. ### Is the iceberg theory the same as subtext? They are closely related. Subtext is the hidden meaning in a line or scene; the iceberg theory is a way of writing a whole work so that its central matter stays beneath the surface. ### How do you use the iceberg theory in a screenplay? Know the hidden story in detail, let characters talk around it, and put the meaning into objects, gestures and silences. Then check with readers that the unstated part comes through. ## Related terms - [Subtext](https://www.inkwell.software/glossary/subtext): What a moment means beneath the spoken words — the real negotiation happening while characters talk about dinner, the case, or the weather. - [Show, don't tell](https://www.inkwell.software/glossary/show-dont-tell): A craft rule: dramatize meaning through action, image, and behavior instead of labeling emotions or themes in dialogue or description.
