Most writing advice tells people to add more. More description. More backstory. More emotional interiority. Layer it on, pile it up, make sure the reader doesn't miss a single thing.
And then someone picks up The Old Man and the Sea--barely 27,000 words, one old fisherman, one marlin, three days at sea--and feels more from that slim book than from 400-page novels packed with overwrought prose. Something doesn't add up.
The gap between what's on the page and what hits the gut. That's the thing that haunts writers at three in the morning. Not "I don't have enough words." The real pain: "I have too many words, and none of them land."
Hemingway had a name for the principle behind this. He called it the Iceberg Theory.
A Story About Cutting
Paris, 1920s. Hemingway worked as a wire-service reporter. Telegraph fees were billed per word--every adjective cost the newspaper real money. Editors slashed without mercy. Modifiers, gone. Qualifiers, gone. Anything that could be removed without destroying meaning: gone.
This experience didn't just teach Hemingway economy. It rewired his relationship with language entirely.
He started asking one question of every sentence: If I delete this, does the reader still understand? If yes, the sentence had no right to exist. Sounds ruthless. But he stumbled onto something counterintuitive: the more explanation he removed, the more intensely readers felt. When he stopped spelling out what characters were thinking, readers connected with those characters on a deeper level.
Psychology explains why. Tell a reader "she was sad" and they register information. That's it. File it away, turn the page. But write "she set her coffee cup on the table and watched the ripples go still, one circle at a time"--now the reader has to fill in the blanks. What happened? Why is she staring? What's that stillness really about?
Filling in blanks turns spectators into participants. And once a reader participates, the emotion isn't something handed to them. It's something they generate themselves. Self-generated emotion always cuts deeper than anything served on a platter.
The core of the Iceberg Theory: write one-eighth. The reader feels the whole thing.
"The Snows of Kilimanjaro": A Masterclass in Omission
A concrete example to tear apart.
The setup of "The Snows of Kilimanjaro" is almost aggressively simple: a writer injured on an African safari, his wound rotting into gangrene, lying in camp waiting for a rescue plane--or for death. The entire story is conversation with his wife, punctuated by italicized memories.
A typical approach might produce something like:
Harry lay on the canvas cot, consumed by regret. All the stories he never wrote, all the wasted years, all the chances he should have grabbed but let slip. He regretted choosing comfort, regretted abandoning his craft for money and women. "I've been running my whole life," he thought, "and now there's nowhere left to run."
Every word is accurate. And the reader feels absolutely nothing. The author pre-chewed every emotion and spoonfed it. No chewing required on the reader's end means no taste.
Hemingway's version:
"Don't you think you ought to write?" she asked.
"I've written," he said. "Everything I had to write."
This was not true. There was so much he had not written. The stories from Paris, the stories from the mountains, what happened in Constantinople...
Then an italicized memory--not about feelings but about a specific, unreturnable afternoon. A street in Paris. A hotel. Light through a window.
Readers finish that passage and understand on their own: this man had a lifetime of stories clenched in his fist, and now his leg is rotting, and the plane isn't coming.
The word "regret" never appears. Not once. But the weight of it fills every silence.
What's underwater doesn't need to be seen. It needs to be felt.
But This Requires Homework
A common misreading of the Iceberg Theory reduces it to "just write less."
Not even close.
The Iceberg Theory means knowing a hundred things and choosing to write twelve. The difference between knowing twelve and writing twelve versus knowing a hundred and writing twelve--that difference is what separates shallow from deep. Even when the surface text looks identical.
Before writing The Old Man and the Sea, Hemingway had lived in Cuba for over a decade. He drank with real fishermen, went out on their boats, listened to their stories. He knew how a marlin's bite shudders through a fishing line, knew the temperature of the Gulf Stream in April, knew the specific calluses that form on a fisherman's hands from years of working rope.
Ninety percent of those details never appear in the book. But they hold up every action, every line of dialogue, every silence. A reader who knows nothing about deep-sea fishing reads the old man handling his line and thinks: this is real. Can't explain why. Just knows.
Authentic things carry their own texture. Walk into a building--even knowing nothing about architecture, a person can sense whether it was built well. That feeling comes from structure, from proportion, from a foundation nobody sees.
So the first step in practicing the Iceberg Theory isn't learning to cut. It's doing the research.
Know the characters--not just their actions in the story but their childhood, their fears, their habits, the food they hate, where their hands go when they walk. These details may never appear in the manuscript, but knowing a person versus inventing a person--readers can tell the difference. In Slima's Writing Studio, separate files for character sheets, setting notes, and background research keep the "underwater homework" out of the main draft. Always there to reference, never cluttering the flow.
Know the settings--smell, light, sound, humidity. Only mention one or two in the actual text. But know all of them. Knowing everything is what makes it possible to choose the most precise detail.
Without this underwater work, the iceberg is just a floating chunk of ice. No dignity. No mass. One wave and it shatters.
Hemingway's Daily Routine
Theory covered. Now: how the man actually worked.
Finca Vigia, Cuba. Six in the morning. Hemingway woke naturally--no alarm. He called this the clearest window his brain gave him, the hours before the world started making noise.
He wrote standing up.
Not a quirk. Standing tires the body, and a tired body writes lean. Sitting is comfortable. Comfort breeds loose sentences, bloated paragraphs, prose that circles itself. Standing makes a person say what needs saying and stop. Slima's Zen Mode produces a similar effect for modern writers--strips the screen of every distraction until only text and cursor remain, pulling attention back to the weight of each word.
First drafts in pencil on paper. The typewriter came later for transcription. Handwriting kept him physically close to the rhythm of language--every stroke had weight in a way that keys sliding under fingers did not.
He wrote until roughly noon. Then stopped.
But the most critical habit was this: he always stopped when he knew what came next.
Most writers do the opposite--write until stuck, then face a dead end the following morning. Anxiety builds. Procrastination spreads. Hemingway reversed the cycle: quit at the peak. The next day, sitting down (or standing up), he didn't need to figure out what to write. He already knew. Just start.
This single trick transforms "beginning to write"--typically the day's hardest action--into the easiest.
He also tracked daily word count. A chart on the wall recording each day's output. Not to punish himself. To see accumulation. Yesterday: 500 words. The day before: 600. A few hundred words a day looks unremarkable, but three months of it produces a first draft. Visible progress makes anxiety retreat. Slima's Writing Studio has built-in word tracking--open a project and the running total is right there, no wall chart required.
Show, Don't Tell--But What Does That Actually Mean?
"Show, don't tell" might be the most repeated sentence in any writing classroom. The problem: hearing it a hundred times still doesn't clarify how to do it.
An extreme scenario to break it open.
A woman discovers her husband's affair.
The "telling" version:
Mary discovered John's affair and felt extreme anger and hurt. She couldn't believe he would do this to her. Twenty years of marriage, destroyed. She felt betrayed, humiliated, deceived.
Every emotion labeled and pinned to the page. The reader receives information but experiences nothing. Someone telling a friend "that movie was terrifying" versus actually sitting in the theater getting scared--entirely different.
The "showing" version:
Mary stood at the washing machine, holding John's shirt. There was a lipstick mark on the collar. Not her color.
She put the shirt in the machine, added detergent, pressed start. Then she sat on the floor beside the washing machine, listening to the drum turn, and stayed there until it stopped.
Zero emotion words. No "angry." No "hurt." No "betrayed."
But the reader knows everything. And because they arrived at it themselves, the feeling hits harder and lingers longer.
The lipstick, the washing machine, the floor--that's the one-eighth above water. Below the surface: twenty years of marriage, the collapse of trust, and the terrifying blank of not knowing what to do next. That blank weighs more than any adjective.
The "underwater part" Hemingway talked about. This is what it means.
When Is "Telling" the Right Call?
"Show" is not doctrine. Hemingway himself didn't show every single sentence.
Some scenes need directness.
When pacing demands speed. A character needs to get from one city to another--no need to render the entire journey in sensory detail. "Three days later, he arrived." Save the showing for scenes that matter.
When background information isn't the point. A character's job is just setting, not theme? "He was an accountant." Done. No need to show him doing the books.
When directness hits harder than demonstration. "The Snows of Kilimanjaro" opens with a flat statement: the man's leg has gangrene. He may die. That sentence drops onto the reader's chest like a stone from the first paragraph, casting the entire story in death's shadow. Showing the wound--its color, its smell, the flies--would actually weaken the cold, fated quality of the declaration.
The real skill is choosing. When to show, when to tell, when to alternate. That judgment is the thing writers actually need to develop.
The Iceberg Theory's Limits
Before enshrining this theory as writing gospel, a cold splash of reality.
Hemingway wrote realist literary fiction. His settings--fishing villages, battlefields, bars, the African plains--exist in the reader's baseline understanding of the world. He could omit enormous amounts of background and readers wouldn't get lost.
Fantasy and science fiction operate differently.
A fully invented world with unique magic systems, social hierarchies, physical laws. Readers have zero prior knowledge. Apply the Iceberg Theory literally--write only one-eighth--and they might not even understand the basic premise, let alone feel any underwater weight. Brandon Sanderson's framework of "soft magic" versus "hard magic" addresses exactly when to explain and when to leave mystery intact. That's a different toolkit, not a direct application of Hemingway's approach.
Reader expectations matter too. Some readers want guidance. They want the author to lay out what characters are thinking, what scenes mean. Hand them a stripped-down text that demands interpretation and their response won't be "how deep" but "how empty."
That's not a reader problem. It's a matching problem.
The Iceberg Theory is a stylistic choice, not a quality metric. It suits certain stories, certain audiences, certain moments. Understanding its boundaries is more valuable than imitating it blindly.
How to Practice: A Concrete Method
For those ready to try this, a step-by-step process.
Step one: Overwrite first.
Don't chase minimalism in the initial draft. Dump everything out--every thought a character has, every layer of emotion, every environmental detail. Let characters say their subtext out loud. Build a bloated, over-explained version. This is raw material, not finished work.
Step two: Let it sit.
At least a day. Ideally a week. Let the memory of what was written fade. Distance produces objectivity. Slima's Version Control earns its keep here--save a Snapshot, tag it "first draft complete," close the file. Come back in a week and pull up that version for side-by-side comparison whenever needed.
Step three: Pick up the red pen.
Reread everything. At every sentence, ask: "If I delete this, does the reader still understand?"
Yes--delete.
Probably yes--also delete.
Keep only the sentences where deletion would genuinely lose the reader.
Step four: Read the trimmed version aloud.
How does it feel? Do the blank spaces carry more tension than the filled ones? Do the unsaid things disturb more than the said ones?
Cut too deep and the reader truly can't follow--add a little back. Find the threshold: one sentence less would be too sparse, one sentence more would be too full. Slima's Split Window lets writers place the original draft on one side and the trimmed version on the other, comparing paragraph by paragraph, judging each cut with precision.
This process hurts. Watching hard-won paragraphs disappear stings. But every unnecessary sentence removed makes the remaining words heavier.
Hemingway's Final Lesson
Hemingway's life was complicated. Nobel laureate. Alcoholic. Suffered from depression. The avatar of literary masculinity--and also someone afraid to be alone at night.
The most important thing he left for writers wasn't the Iceberg Theory. Wasn't about style.
It was this:
"All first drafts are shit."
Even Hemingway said that.
What it means: the real work of writing doesn't happen in the first pass. The first draft is the writer talking to themselves--figuring out what the story is actually about. Revision is the writer talking to the reader--deciding which one-eighth to reveal.
So don't fear writing a terrible first draft. Don't fear too many words, too much explanation, too much sprawl. Haul the entire iceberg onto the table first, then take the red pen and the delete key and carve it down to one-eighth.
Slima's AI Beta Readers can offer a second perspective during the carving process--pointing out where readers "already get it, no need to say more" and where "too much was cut, lost the thread." Not a replacement for the writer's own judgment, but an extra pair of eyes. More eyes are always better than fewer.
An iceberg was never born perfect. It was carved toward perfection.
The End of This Series
This is the final piece in the "Habits of Master Writers" series. Four writers, four methods.
- Stephen King: Write every day, read massively, close the door for the first draft, open it for revision. Fueled by instinct and passion.
- Haruki Murakami: Wake at four a.m., write five hours, run ten kilometers. Treat writing like a marathon--let a disciplined body sustain a disciplined practice.
- Brandon Sanderson: A systematized creative engine. Multiple projects running in parallel, detailed outlines, structured worldbuilding. Outlines aren't cages. They're freedom.
- Hemingway: Know a hundred things, write twelve. Trust the reader's intelligence. Cutting is creation.
King: fierce and instinctive. Murakami: calm and disciplined. Sanderson: structural and precise. Hemingway: minimal and deep.
Their only shared trait: each found their own method, then executed it for decades.
No method is "correct." No method is "best." Only "right for the individual."
Maybe some writers resemble King--driven by impulse and gut feeling. Maybe others resemble Murakami--needing ironclad routine to sustain long-term output. Maybe some thrive like Sanderson, building systems and frameworks to solve creative problems. Maybe others chase Hemingway's ideal, demanding that every word be irreplaceable.
Or some mixture of all four. Most people are.
Find the method that fits. Then keep going.
That's the only path to becoming a writer--no shortcut, no template, just the act of sitting down (or standing up) and writing, again and again.
