0. A Brief Recap of the Endorphin Philosophy
Modern society keeps promising relief from pain— but always through stronger pleasure. More stimulation. More reward. More dopamine. The problem is obvious: this path is neither sustainable nor universally accessible. That’s why I proposed an alternative framework: the Endorphin Philosophy. The core idea is simple.
- Overwhelming pain should be avoided.
- But a small, manageable discomfort—around 1%—can enrich life.
Crossing that small hurdle creates immersion. Immersion generates repeatable calm. Unlike dopamine loops—which demand constant novelty and escalating rewards—endorphin rhythms are stable. They don’t rely on excitement. They rely on embodied familiarity. In earlier essays, I critiqued Dr. Anna Lembke’s pain–pleasure seesaw, arguing that pain is not always something to eliminate. Sometimes, pain is the gateway to flow, mastery, and even quiet ecstasy. (Part 1—General Theory | Part 2—Applications in F&B | Part 3—Living the Endorphin Philosophy)
This article pushes the framework one step further—into the territory of habit. Specifically, I will examine Nir Eyal’s Hooked model, explain why it fails to produce genuine habits, and show its structural limits in sustainability and scalability. Then, I’ll lay out an alternative: endorphin-based habit formation, grounded in real-world, embodied examples—not behavioral engineering fantasies.
1. Nir Eyal’s Hook Model: A Summary
(1) The Core Idea
Nir Eyal proposes a four-stage cycle to answer a simple question: “How do we get people to use a product habitually?”
Answer: Trigger → Action → Variable Reward → Investment → (repeat)
Twitter is his go-to example.
- A notification arrives. (external trigger)
- The user already feels bored or isolated. (internal trigger)
- With a single thumb tap, they open the app and start scrolling. (action)
- Memes, updates, jokes—short bursts of pleasure appear unpredictably. (variable reward → dopamine)
- The user posts a tweet, waiting for likes and retweets. (investment)
That expectation pulls them back into the loop.
(2) Why the Model Was So Influential
The strength of Hooked is obvious. It systematized Silicon Valley’s core anxiety: How do we keep users coming back without them getting bored? For app founders, the model felt powerful—even seductive.
But here’s the problem. If human behavior really worked in four clean steps, anyone could build an app and get rich. The fact that “dopamine capitalism” leaves so many people restless, anxious, and empty already hints at the model’s limits. So let’s look at those cracks more closely.
2. The Logical Limits of the Hook Model
(1) Dopamine Triggers Are Not Habits
Eyal treats habit as a conditioned reflex. Design the right triggers and variable rewards, and people will move automatically. But that isn’t habit. That’s dopamine-driven compulsion. A pigeon pecking a lever for food pellets isn’t forming a habit. It’s trapped in a stimulus–response loop. Conceptually, dopamine and habit point in opposite directions:
- Habits are familiar, unconscious, embodied routines.
- Dopamine spikes only in response to novelty, surprise, or heightened reward.
No one feels a dopamine rush from driving the same route to work. This is real habit—stable, everyday routine, bodily rhythm. Not compulsions. What the Hook model describes is addiction engineering, not habit formation.
(2) What Habit Really Is: The Endorphin View
Consider a chef making a roux. He doesn’t check a timer. He feels it’s time. He opens the freezer—just in case—and sees the roux stock is low. Butter melts. Flour falls in. The whisk moves without conscious thought. His wrist feels strain. His nose catches the nutty aroma. The color shifts from white to blond to golden brown. The viscosity thickens, pulling against the whisk. No calculation. No checklist. The body knows. When it’s done, he spreads it on a tray and feels quiet satisfaction.
Here, habit looks like this:
1% pain (effort, tension) + endorphin calm (flow, mastery)
Habits are forms of embodied comfort. They don’t feel forced. They feel like who we are. As Merleau-Ponty argued, a habit is a way of perceiving the world— action flowing without conscious calculation.
That’s why someone who follows a recipe step by step doesn’t yet feel like a real chef. Their actions haven’t settled into the body. There’s still distance between the person, the tools, and the ingredients. The kitchen isn’t yet part of their world.
If you still have to calculate: how many grams of butter, how long to stir, when to lower the heat, then cooking hasn’t become embodied knowledge. Habits tint perception the way sunglasses tint the world.
They quietly stabilize reality. And once formed, habits are hard to change—because changing a habit isn’t just changing behavior. It’s changing the world you live in. This is not dopamine-driven craving. It’s sustained by comfort, familiarity, and bodily trust.
Let’s call this an endorphin habit. (Compared to Dopamine Compulsion)
(3) When Do Endorphin Habits Change?
Habits are stable—but not eternal. Take Google. Eyal cites Google as a habitual product: simple, frequent, useful. But Google didn’t hook users through variable rewards. It became skin-sticky. Google’s stickiness was not achieved through behavioral addiction engineering or variable rewards; it mutated into an invisible extension of human curiosity itself. The core of Google’s endorphin habit lay in its invisibility. By keeping the interface an unadorned void, it zeroed out the cognitive switching cost of thought. The user does not ‘consume’ Google; rather, Google fades into the background baseline of perception, becoming a trusted bodily reflex—an extra organ for decoding reality. It became skin-sticky because it ceased to be an external product and became the very lens through which we view the world.
The goal was simple:
Be everywhere. Stay invisible.
- Hook → compulsive, novelty-driven, brittle
- Endorphin habit → embodied, calm, sticky, world-shaping
(4) Why Hook Can’t Scale Beyond Platforms
Before moving on, one final question: Why can’t the Hook model scale to industries like dining or consumer goods? Because dopamine pumping isn’t free. A hook breaks the moment stimulation stops. And stimulation costs money. Platforms like Twitter outsource novelty to users who upload contents. Restaurants can’t. Applying Hook to dining means endless spectacle:
- Eleven Madison Park’s hot-dog cart
- The Fat Duck’s seashell headphones
Yes—dopamine spikes. But novelty escalates into an arms race: more extreme, more expensive, easily copied. Even Danny Meyer admitted that theatrics don’t create repeat visits and destroy cost structures. So the conclusion is simple:
Hook is not habit. It’s compulsion. And compulsion demands constant, costly stimulation.
Endorphin habits rely on small friction + deep comfort. That rhythm sustains itself. And it cost less. So the real question becomes: How do we build endorphin-habit brands?
3. The HABIT Principle: Building Endorphin Habit Brands
(1) Hook vs. Endorphin Habit — Comparison Table
| Aspect | Dopamine Hook (Nir Eyal) | Endorphin Habit (Saltnfire) |
|---|---|---|
| Core Cycle | Trigger → Action → Variable Reward → Investment | 1% hurdle → Immersion → Calm routine |
| Mechanism | Novelty & surprise trigger dopamine | Repetition embeds into body & world |
| Behavior | Reflexive, compulsive, tense expectation | Unconscious, stable, embodied perception |
| Sustainability | Breaks without constant stimulation | Endures without external novelty |
| Scalability | Escalating cost of stronger stimuli | Low-cost, naturally woven into life |
| Examples | Twitter, Pinterest, TikTok (infinite scroll) | Google (search), Starbucks (consistency), cooking roux |
| Philosophy | Behaviorism, conditioned reflex | Zhuangzi + Endorphin philosophy |
(2) The HABIT Framework
From my own writing and cooking routines, I’ve distilled five conditions that allow a product to stick to the skin—to become an endorphin habit rather than a dopamine hook.
H — Harmony
Not surprise, but seamless stability. A true habit doesn’t announce itself. It disappears into daily life. Your favorite pair of jeans is a perfect example. They fit so naturally that you forget you’re wearing them. Nothing “exciting” happens—yet that quiet stability is precisely why they endure. Habits don’t interrupt life. They merge with it.
A — Accessibility
A product must feel usable before you think about using it. It must always be around us without us even realizing it, just like infrastructure such as water and air. Apple’s MacBook works because you open the lid—and you’re already working. The near-zero switching cost between MacBook, iPhone, and iPad creates a bodily illusion: as if your hands and eyes have been extended into the device. When access feels that natural, repetition follows effortlessly. That’s how usage turns into habit.
B — Bump & Comfort
As the saying goes, ‘Easy come, easy go.’ Conversely, what we learn with effort sticks with us longer. Pure, frictionless convenience is inherently forgettable. For an experience to settle into the permanent memory of the body, it demands a ‘1% hurdle’—an intentional point of resistance that amplifies the subsequent 99% comfort. This is the physiological law of contrast.
Just as the tension of untangling a high-fidelity wired headphone transforms the act of listening into a sacred, isolated ritual, a curated friction breaks the numbing flow of everyday routine. Coffee, cigarettes, and whiskey are bitter. Yet that bitterness makes rest feel deeper. Pure convenience is forgettable. Comfortable feeling requires a small hurdle — not dopamine stimulation, but embodied contrast is essential for truly appreciating comfort. True, sustainable comfort is not a state of passive stimulation; it is a release engineered through the resolution of a small, embodied limitation.
I — Investment Value
Endorphin habits must make economic sense. Notion keeps churn low because most features are free. But even expensive products can form habits if they last. Durability matters more than price. A Toyota car is a classic example. Once your body adapts to the steering, pedals, and acceleration curve, switching brands feels unnecessary—even uncomfortable. Low depreciation over time is a powerful habit engine.
T — Tie to Identity
A habit is complete only when it becomes who you are. We perceive the world through our habits. So a habit must connect to identity:
- “I’m the kind of person who goes to this pub.”
- “I use this phone.”
- “I like this kind of café.”
Every object carries fragments of a lifestyle. We stitch those fragments together to make sense of ourselves. That’s when use becomes meaning.
The Core Insight
Together, these five elements—Harmony, Accessibility, Bump & Comfort, Investment Value, and Identity—transform a product from something you use into something you embody. That is an endorphin habit.
4. Endorphin Habit Case Study
(1) Korean Optical Shop
Glasses aren’t accessories. They’re part of your eyes. You wear them all day. When they fit well, you forget they’re there. Occasionally, there’s 1% discomfort—fogging, slipping, smudging. But the moment you take them off to clean them, you realize how dependent you are.
That brief inconvenience deepens attachment. In Korea, optical shops actively design this endorphin loop. They handle: eye exams, lens calibration, frame selection, repeated fittings. Until glasses feel like part of the body. As a result, customers don’t become loyal to frame brands. They become loyal to the shop. In Europe, brand loyalty dominates. In Korea—where over 70% of people wear glasses—frame brands are almost invisible. The winners are optical franchises that manage the habit itself.
(2) Levi’s
Levi’s is denim you keep for years—even after it wears thin. Levi’s has long invested in materials that adapt to the body: cotton as the base, a small amount of spandex for durability and movement. At first, the jeans feel stiff. Over time, they soften, bend, and mold—becoming uniquely yours. This is the opposite of fast fashion brands like Zara or H&M, where trend, color, and silhouette matter more than longevity.
Levi’s builds endorphin stickiness through material aging. Today, that physical habit is reinforced by storytelling: freedom, labor, and the American frontier. With 150+ years of heritage, Levi’s isn’t just selling jeans. It’s selling the identity of “the most American denim.”
(3) Food & Beverage
Many of the restaurants I’ve analyzed—American dive bars, workplace cafeterias, or Prague’s Havelská Koruna—are not glamorous Michelin-starred destinations. They are routine places.
People don’t visit them to be impressed. They go because it’s Tuesday, because it’s after work, because this is just where they go. These places don’t rely on shows or gimmicks. No surprise performances. No dopamine spectacles. And precisely because of that, something else happens: People talk more. They linger. They stack today’s visit on top of yesterday’s memory. Over time, the shop itself becomes meaningful. Endorphin-style venues often look old. Sometimes slightly messy. Occasionally inconvenient. Yet they are:
- woven into daily life
- affordable
- emotionally stable
- structurally sustainable
Small, resilient businesses survive here—not on hype, but on repeated comfort.
(4) HABIT Principle — Case Study Summary
| HABIT Element | Korean Optical Shops | Levi’s | Endorphin Restaurants |
|---|---|---|---|
| H — Harmony | Stable, predictable use | Fit improves with wear | Routine visits (cafeterias, dive bars) |
| A — Accessibility | One-stop eye test + fitting | Global retail availability | Low prices, simple menus, fast decisions |
| B — Bump & Comfort | Fogging/slipping → clarity restored | Stiff at first → comfort over time | Old, messy, noisy → comfort once seated |
| I — Investment Value | Mid-priced but essential & long-lasting | Durable denim worn for years | Affordable meals, high repeat value |
| T — Tie to Identity | “I go to this shop” | “The most American jeans” | Place tied to memory, routine, belonging |
Endorphin habits do not depend on excitement. They depend on: bodily familiarity, small friction followed by relief, long-term value, and identity reinforcement. That’s why cafeterias and dive bars—despite looking unimpressive— often outlast trend-driven restaurants with better interiors and louder marketing. Brillat-Savarin said: “Tell me what you eat, and I will tell you who you are.” I say this: “Show me your habits, and I will tell you who you are.”
5. Conclusion
This article examined how Endorphin Philosophy extends into habit formation. We contrasted:
- Nir Eyal’s Hook model — a dopamine-driven compulsion loop with
- Endorphin habits — calm, embodied routines that attach to daily life
Glasses are the clearest example: worn all day, forgotten, briefly removed—then immediately missed. Levi’s jeans, Korean optical shops, dive bars, and cafeterias all follow the same rhythm:
a small bump → deeper comfort → identity reinforcement.
The HABIT framework— Harmony, Accessibility, Bump & Comfort, Investment Value, and Tie to Identity— explains how products and places stop being “used” and start being lived with. This is attachment without exhaustion.
“Endorphin habits — stick like skin, flow like life.”
