Iceberg theory

The Art of Leaving Things Out
In 1923, Ernest Hemingway finished writing a short story called "Out of Season." The story ends with an old man walking away after a failed fishing expedition. What Hemingway didn't write—what he deliberately cut from the manuscript—was that the old man went home and hanged himself.
This act of omission changed literature.
Hemingway realized something that seems counterintuitive: by removing the suicide, he had made the story stronger. The reader couldn't point to anything specific that was wrong, but they could feel something terrible lurking beneath the surface. The weight of what wasn't said pressed down on everything that was.
He called this the iceberg theory, though it's sometimes known as the theory of omission. The idea is deceptively simple. When you see an iceberg floating in the ocean, only about one-eighth of its mass is visible above the waterline. The vast majority—the part that gives the iceberg its stability, its danger, its mass—remains hidden beneath the surface. Hemingway believed fiction should work the same way.
A Journalist's Education
Before Hemingway became the most influential prose stylist of the twentieth century, he was an eighteen-year-old cub reporter at The Kansas City Star. He had just graduated from high school in Oak Park, Illinois, and instead of going to college, he took a job at the newspaper.
It was 1917. America had just entered the First World War. The Star was considered one of the best newspapers in the country, with a famous style guide that demanded short sentences and direct language. Young reporters were told to use vigorous English, to avoid adjectives when possible, to never write anything that made them seem clever.
Hemingway covered the police beat. He spent time in hospital emergency rooms and city jails. He learned that cops and doctors wore cynicism like armor, protecting whatever vulnerabilities remained underneath. More importantly, he learned that truth often hides. The real story was rarely what people told you. It was what they carefully avoided saying.
This was his first lesson in omission.
A few years later, working as a foreign correspondent for the Toronto Star, Hemingway covered the Greco-Turkish War of 1919-1922—a brutal conflict that saw massive population transfers and widespread atrocities as the Ottoman Empire collapsed into the modern nation-states of Greece and Turkey. He wrote more than a dozen articles from the front lines.
His biographer Jeffrey Meyers describes Hemingway's approach: he "objectively reported only the immediate events in order to achieve a concentration and intensity of focus—a spotlight rather than a stage." He didn't explain the complex history. He didn't provide context about the centuries of ethnic tension. He just described what he saw, trusting that the specificity of detail would communicate what analysis could not.
Making Things Truer Than True
When Hemingway moved to Paris in the 1920s to become a fiction writer, he brought his journalist's instincts with him. But he also discovered something new: in fiction, you could use reality as raw material and then shape it into something that communicated more than mere facts ever could.
"What he made up," Hemingway believed, "was truer than what he remembered."
This is a strange idea, worth pausing over. How can an invented story be truer than a real memory? The answer has to do with the difference between information and experience.
When you read a newspaper report about a war, you receive information. You learn that certain events occurred, that certain people died, that certain territory changed hands. But unless you've been in a war yourself, the words remain abstract. They don't make you feel anything in your body.
Hemingway wanted his fiction to transfer experience directly into the reader. Not facts about experience—the experience itself. He believed this required stripping away everything that got in the way: explanations, interpretations, the author's own feelings about what happened.
In his posthumously published memoir A Moveable Feast, Hemingway describes the moment he formulated his new theory:
I omitted the real end [of "Out of Season"] which was that the old man hanged himself. This was omitted on my new theory that you could omit anything... and the omitted part would strengthen the story.
The key phrase is "the omitted part would strengthen the story." Not weaken it through absence. Strengthen it through the pressure of what's missing.
The Invisible Structure
Hemingway wasn't the first writer to discover the power of restraint. He learned much of his technique from reading Rudyard Kipling, the British author of The Jungle Book and Kim, who was famous for his compressed, muscular prose. From Kipling, Hemingway absorbed the practice of cutting sentences down to the absolute minimum they could bear.
But Hemingway pushed the technique further. He made it systematic.
In an essay called "The Art of the Short Story," he explained his method:
If you leave out important things or events that you know about, the story is strengthened. If you leave or skip something because you do not know it, the story will be worthless. The test of any story is how very good the stuff that you, not your editors, omit.
This distinction matters enormously. The iceberg theory only works if the writer actually knows what's underwater. You can't fake depth by simply being vague. The reader will sense it. The story will feel hollow instead of heavy.
Hemingway's biographer Carlos Baker puts it this way: the young writer learned "how to get the most from the least, how to prune language and avoid waste motion, how to multiply intensities, and how to tell nothing but the truth in a way that allowed for telling more than the truth."
That last phrase—"telling more than the truth"—captures something essential. When Hemingway wrote about a man fishing in a river, he was also writing about trauma, about the desperate need for routine and control after experiencing horrors that can't be processed. But he never mentioned the trauma directly. He just described the fishing.
Big Two-Hearted River
Consider one of Hemingway's most famous stories, "Big Two-Hearted River." On the surface, almost nothing happens. A young man named Nick Adams arrives by train in a small Michigan town that has been destroyed by fire. He hikes into the wilderness. He sets up camp. He catches grasshoppers for bait. He fishes. He eats. He sleeps. He fishes some more.
That's the entire plot.
Yet the story is devastating. Readers have found themselves moved to tears by descriptions of a man making buckwheat pancakes.
How does this work?
Hemingway explained it directly: "It is about a boy... coming home from the war... So the war, all mention of the war, anything about the war, is omitted."
Nick Adams is a shell-shocked veteran. He has seen things that have damaged him in ways he can't articulate. The meticulous attention he pays to every small task—setting up the tent just so, preparing his coffee with exact precision, handling the fish with careful attention—these aren't the behaviors of a man enjoying nature. They're the behaviors of a man who cannot afford to let his mind wander for even a moment, because if it does, the horrors will come flooding back.
None of this is in the text. All of it is in the text.
Hills Like White Elephants
Hemingway pushed the iceberg theory even further in "Hills Like White Elephants," a story that consists almost entirely of dialogue between a man and a woman sitting at a train station in Spain, waiting for the express to Madrid.
They drink beer. They look at the hills. They talk about "it"—some procedure that the man wants the woman to have.
The word "abortion" never appears in the story.
Neither does the word "pregnancy."
The man keeps telling the woman that "it's really an awfully simple operation" and "it's not really an operation at all." He says he's known "lots of people that have done it." The woman asks if things will be like they were afterward, and the man says yes, and she clearly doesn't believe him.
The tension is unbearable. The reader understands everything that's at stake—a relationship, a potential child, the woman's bodily autonomy, the man's desire to maintain his carefree lifestyle—without any of it being stated. The story communicates entirely through what it refuses to say directly.
The Risk of Distance
Hemingway scholar Jackson Benson identifies another function of the iceberg theory: it created distance between Hemingway and his characters.
This matters because so much of Hemingway's fiction drew on his own experiences. He had been wounded in the First World War. He had struggled with trauma. He had difficult relationships with women. His father had committed suicide.
If he had written about these experiences directly, pouring his own feelings onto the page, the result might have been self-indulgent or maudlin. By forcing himself to omit the emotional core—by making himself write around the wound rather than about it—he achieved a kind of objectivity that paradoxically made the emotions more powerful.
Benson argues that this technique worked brilliantly in Hemingway's early fiction, particularly in The Sun Also Rises, his first major novel about American and British expatriates in 1920s Paris and Spain. The protagonist, Jake Barnes, has been wounded in the war in a way that has left him impotent. This devastating injury is mentioned only obliquely, and Jake's feelings about it are almost never discussed. Yet his wound shapes everything in the novel.
But Benson also warns that the technique requires deliberate effort. In Hemingway's later work, particularly in Across the River and into the Trees, the distance collapsed. The author got too close to his protagonist, and the fiction suffers for it. When the iceberg rises above the water, it loses its power.
A Clean, Well-Lighted Place
One more example shows how the iceberg theory operates.
"A Clean, Well-Lighted Place" is a short story about two waiters in a café late at night. An old man sits alone at a table, drinking brandy. He is deaf and has recently tried to kill himself.
One waiter—the younger one—wants to close up and go home. The other waiter—the older one—understands why the old man stays. The café is clean and well-lighted. Outside, there is darkness.
On the surface, the story is about nothing. Two men talking about a third man who drinks alone at night. But underneath, the story is about despair, about the void, about the human need for order and light against the chaos and darkness that threatens to overwhelm us. The older waiter, we come to understand, is not so different from the old man. He too struggles to sleep. He too fears the nothing—the "nada"—that waits outside the illuminated circle.
Near the end of the story, the older waiter recites a kind of prayer:
Our nada who art in nada, nada be thy name thy kingdom nada thy will be nada in nada as it is in nada. Give us this nada our daily nada and nada us our nada as we nada our nadas and nada us not into nada but deliver us from nada; pues nada.
It's the Lord's Prayer, emptied of meaning. God replaced by nothing. And yet somehow this nihilistic parody communicates more about existential dread than any number of philosophical treatises could.
The Nobel Prize
In October 1954, Hemingway received the Nobel Prize in Literature. The Swedish Academy cited "his mastery of the art of narrative, most recently demonstrated in The Old Man and the Sea, and for the influence that he has exerted on contemporary style."
That phrase—"the influence that he has exerted on contemporary style"—is almost an understatement. Hemingway's spare, direct prose became the dominant mode of American fiction for decades. Writers as different as Raymond Carver, Cormac McCarthy, and Joan Didion owe debts to his approach. Even writers who consciously rejected his influence—like the maximalist Thomas Pynchon or the ornate Toni Morrison—defined themselves partly in opposition to what Hemingway had established.
A few days after winning the prize, Hemingway spoke with a reporter from Time magazine while fishing off the coast of Cuba. The reporter asked about symbolism in The Old Man and the Sea—about the old fisherman as Christ figure, about the marlin as nature, about what it all meant.
Hemingway's answer is worth quoting at length:
No good book has ever been written that has in it symbols arrived at beforehand and stuck in... That kind of symbol sticks out like raisins in raisin bread. Raisin bread is all right, but plain bread is better.... I tried to make a real old man, a real boy, a real sea, a real fish and real sharks. But if I made them good and true enough they would mean many things. The hardest thing is to make something really true and sometimes truer than true.
This is the iceberg theory expressed as craft advice. Don't start with what you want to mean. Start with what is real. Get the surface exactly right—the weight of a fish on a line, the way light falls on water, the specific ache in an old man's hands—and the meaning will take care of itself. The depth emerges from the precision of the surface.
The Reader's Work
Scholar Zoe Trodd offers another perspective on how the iceberg theory functions. She argues that Hemingway's technique is not passive—it "demanded that the reader feel the whole story." The reader must actively participate, filling "the gaps left by his omissions with their feelings."
This turns reading into a collaborative act. Hemingway provides the tip of the iceberg; the reader supplies the rest from their own experience and imagination. When it works, the result is more powerful than if everything had been spelled out, because the reader has invested their own emotional resources in constructing the meaning.
It's a high-wire act. If the writer omits too much, the reader has nothing to work with. If the writer includes too much, the reader becomes passive, merely receiving information rather than participating in the creation of meaning. The balance requires exquisite judgment about what to leave in and what to take out.
As critic Ben Stoltzfus puts it: "Hemingway walks the reader to the bridge that he must cross alone without the narrator's help."
The Danger of Influence
Hemingway's influence on American prose was so enormous that it created its own problems. A generation of writers tried to imitate his style without understanding the theory behind it. They wrote short, declarative sentences. They avoided adjectives. They left out context and explanation.
But they didn't know what they were omitting, because they hadn't done the work to understand it themselves. The result was a lot of fiction that was merely thin—not icebergs with vast hidden depths, but ice cubes floating on the surface.
This is the trap of influence. When a technique becomes a style, it loses its power. Hemingway's sentences were short because he was compressing enormous amounts of information into small spaces. When lesser writers imitated the short sentences without the compression, they produced merely choppy prose.
Hemingway himself understood this danger. In "The Art of the Short Story," he warned that omission only works "if you knew that you omitted." The knowledge is the key. The iceberg's power comes not from what's missing, but from what's present but invisible—the vast mass of understanding that the writer possesses and chooses not to state directly.
Truer Than True
At the heart of the iceberg theory is a paradox. By leaving things out, you put more in. By refusing to explain, you communicate more. By writing about a man fishing in a river, you write about the unspeakable trauma of war. By showing two people talking in a train station, you illuminate the devastating negotiations of intimacy and autonomy.
Hemingway believed that fiction's purpose was to transfer experience—not to describe it, but to make the reader feel it in their body. This required stripping away everything that interfered with the transfer: the author's opinions, the explanations, the interpretations, the context. What remained was pure sensation, pure action, pure dialogue.
But underneath the surface, holding it all up, was everything the author knew and chose not to say.
"The hardest thing," Hemingway told the Time reporter, "is to make something really true and sometimes truer than true."
This is what the iceberg theory offers: a way of writing that achieves truth not through completeness but through selection, not through explanation but through implication, not through telling but through the terrible pressure of everything that remains untold.
