The enemy, the Heaths argue, is the Curse of Knowledge — the predictable cognitive failure that causes smart people who understand their subject to communicate it in ways incomprehensible to people who don’t. Every principle in the SUCCESs framework is a weapon against this curse. If your ideas aren’t sticking, it’s not because your audience is dumb. It’s because your communication is violating the principles of how human memory works.
Cold Open
Researchers at Stanford gave students a list of statistics about crime in the United States and asked half of them to give a one-minute persuasive speech using that data. Then they asked listeners to recall the speeches. On average, listeners remembered 2.5 statistics from each speech. They also remembered the stories speakers used — 63% of listeners remembered at least one story from speeches that contained them, compared to 5% who remembered a single statistic from speeches relying on data alone.
Stories aren’t simply more engaging than statistics — they get processed differently by the brain, stored more durably, retrieved more reliably. Not a preference or a cultural artifact. A consequence of how human memory is organized: around narratives, concrete images, and emotional resonance rather than abstract propositions and factual databases. The Heaths’ book is an extended investigation of this finding and its practical implications for anyone who needs to communicate ideas that stick.
Key Lessons from Made to Stick
- The Curse of Knowledge — the inability to imagine what it is like to not know something you know — is the primary barrier to effective communication.
- Simple ideas are stripped down to their core essence, not dumbed down — find the single most important thing and communicate that first.
- Unexpected ideas violate the listener’s mental model, opening a gap of curiosity that the communicator can fill.
- Concrete ideas are expressed in sensory language and specific examples, not abstractions — abstractions cannot be remembered.
- Credible ideas include specific, unexpected details that signal the communicator knows what they are talking about.
- Emotional ideas connect the message to the listener’s individual self-interest or identity — people care about people, not statistics.
- Stories are the most powerful communication technology available — they simulate experience and make abstract ideas concrete and memorable.
- The testing question for any communication: if the listener could remember only one thing from this, what should it be? If you cannot answer this question, neither can they.
Plain Truth on Made to Stick
Rating: 9/10 — essential reading for anyone who communicates ideas for a living, which is most people.
The SUCCESs framework is memorable, applicable, and empirically grounded. The Heaths practice what they preach: the book itself is structured around memorable examples, concrete case studies, and unexpected findings that illustrate each principle. The Curse of Knowledge concept alone is worth the price of the book — it explains communication failures that previously seemed mysterious, and points directly at the solution. The book’s occasional tendency to hammer a point with one more example than necessary is a minor flaw in an otherwise tightly executed work.
The Core Idea Behind Made to Stick
Ideas that stick share six properties, which the Heaths package into the acronym SUCCESs: Simple, Unexpected, Concrete, Credible, Emotional, Stories. Each property addresses a specific cognitive challenge communication must overcome to produce lasting memory and behavior change.
Simple means ruthlessly prioritizing — finding the core of an idea and stripping away everything that isn’t that core. Not dumbing down. Focusing. An idea with five equally important points gets remembered with zero. An idea with one clearly dominant point gets remembered for decades. Southwest Airlines’ core strategy — be the low-cost airline — is simple. Everything the company does flows from that single idea. That simplicity is a communication and decision-making asset, not a limitation.
The Curse of Knowledge is the central villain the framework fights. Once you know something, you can’t imagine what it’s like not to know it. You communicate it at abstraction you experience it at, which is incomprehensible to someone encountering it for the first time. Every principle in SUCCESs is a forcing mechanism that combats the Curse: concrete language forces you out of abstraction, unexpected structure forces you to consider your listener’s mental model, stories force you to ground abstract ideas in specific human experience.
“The most basic way to get someone’s attention is this: Break a pattern. We adapt to the ordinary and predictable. The unexpected naturally demands attention.”
Chapter-by-Chapter Breakdown
Simple — Finding the Core. Simplicity in the Heaths’ framework doesn’t mean easy or shallow — it means prioritized. Creating a simple message means deciding what’s most important and ruthlessly excluding everything else. The Heaths use the concept of “the commander’s intent” from military doctrine: every military order must include a single clear statement of what success looks like, so soldiers can make good decisions in the chaos of battle when no commander is available. A message without commander’s intent — without a single clear priority — leaves the audience unable to act when conditions change.
The proverb is their model for communication excellence: “A bird in the hand is worth two in the bush” encodes a complex principle about certainty, risk, and value in ten words anyone can remember and apply. Great communication has proverb-like clarity — a compact core that can be remembered and reapplied in new contexts without effort. Finding that core means identifying not the most important of many things, but the single most important thing.
Unexpected — Breaking Patterns. The human attention system is designed to notice deviations from patterns, not to maintain sustained engagement with predictable content. The first sentence of a message has to violate the listener’s expectations enough to create curiosity. The Heaths distinguish surprise — a one-time disruption that gets attention but doesn’t sustain it — from mystery — a maintained knowledge gap that keeps attention engaged until it’s resolved.
The mystery principle is their prescription for sustained communication engagement: don’t reveal the answer immediately. Raise a question first. Make the listener aware of a gap in their knowledge. Then fill the gap. This sequence — question before answer, problem before solution — is more engaging than the reverse, even when the answer’s the same, because it leverages the brain’s natural drive to close knowledge gaps.
Concrete — Breaking the Abstraction Habit. Abstractions can’t be remembered because they have no sensory referent — no image, sound, texture, or smell associated with them. “A bird in the hand” gets remembered because you can visualize it. “Certainty is preferable to probabilistic outcomes” doesn’t get remembered because there’s nothing to visualize. Concrete language forces the communicator to describe actual things, actual people, actual events — the only categories the human memory system reliably stores.
The Heaths use Aesop’s fables to illustrate this. Aesop communicated complex moral and philosophical principles about human behavior through stories involving specific animals in specific situations. The specific and concrete story encodes the abstract principle more reliably than any direct statement of the principle could. The listener who remembers “the tortoise and the hare” always has access to the principle of persistence versus complacency. The listener trying to remember “persistence outperforms talent in long-term competition” has a much harder task.
Credible — Generating Belief. Ideas have to be believed before they can be acted on. The Heaths identify two categories of credibility operating differently. External credibility — endorsement from experts, authorities, institutions — is the most familiar. But internal credibility — the specific, unexpected details that signal genuine knowledge from inside the experience — is often more powerful and more accessible.
Their example is memorable: a claim the Ronald Reagan campaign made during a debate with Carter — “Are you better off now than you were four years ago?” — was internally credible because it gave the listener a specific, personal test they could apply. The listener’s own experience was the proof. Messages that let listeners validate the claim through their own experience are more credible than messages relying entirely on external authority, because they can’t be refuted by challenging the authority.
Emotional — Making People Care. The most common failure mode for expert communicators is assuming that if the case is intellectually compelling, behavior will follow. Research consistently shows emotional engagement is required for action, not just intellectual agreement. People can understand and agree with a message about climate change, obesity, or financial planning without being moved to act on it — because the message failed to connect to anything they care about on an emotional level.
The Heaths identify self-interest and identity as the two most powerful emotional levers. Self-interest is straightforward: messages that answer “what’s in it for me?” with specificity and vividness produce more action than messages appealing to abstract benefits. Identity is more powerful: messages connecting the desired behavior to who the listener is — or aspires to be — produce the most durable change, because they tap into the deepest emotional commitments people have.
Stories — The Master Format. The final principle integrates all the others: stories are naturally simple (beginning, middle, end), unexpected (good stories involve problems), concrete (specific people in specific situations), credible (accounts of things that happened), emotional (characters we identify with), and they are stories. Research on narrative processing suggests stories engage the brain differently from propositions: listeners mentally simulate the story, producing something closer to experience than argument does.
The Heaths classify stories into three archetypes based on the action they prompt: Challenge stories (someone overcomes adversity — inspires action), Connection stories (someone bridges a gap between people or groups — inspires relationship), and Creativity stories (someone solves a problem in an unexpected way — inspires innovation). Different communication goals call for different story archetypes, and understanding which archetype serves your goal is part of the design process.
What Made to Stick Gets Right
The Curse of Knowledge concept is the book’s single most important contribution, and it reframes communication failure in a way both more accurate and more actionable than most communication advice provides. Telling people to “communicate more clearly” or “know your audience” doesn’t diagnose why communication fails. The Curse of Knowledge identifies the specific cognitive mechanism — the inability to imagine ignorance of what you know — and the specific failure mode it produces: communication at the wrong level of abstraction for the audience.
The SUCCESs framework is comprehensive enough to cover the major dimensions of sticky communication while staying compact enough to apply in practice. Each principle addresses a specific, identifiable failure mode. Applied systematically to any communication — a speech, an article, a product description, a marketing campaign — the framework reliably improves retention and action rates.
The storytelling chapter is among the best practical treatments of narrative in communication available outside specialized screenwriting and fiction guides. The three-archetype classification (challenge, connection, creativity) is a useful design tool preventing the vague injunction to “tell stories” from becoming the vague prescription it usually is.
Where Made to Stick Falls Short
The framework occasionally produces tension between principles. Making an idea maximally simple and maximally concrete can conflict: the most concrete version of an idea is often more complex than the simplest. The Heaths acknowledge this tension but don’t resolve it as systematically as the individual principles get developed.
The book is more useful for communicating ideas that are already correct than for creating the underlying ideas themselves. The sticky idea framework assumes you know what you want to communicate and helps you communicate it more effectively. It doesn’t help with the harder prior question of whether your idea is worth communicating — which is often the more important question.
The Protocol: Making Your Ideas Sticky
- Find the core. What is the single most important thing you want the listener to remember? If they could remember only one thing, what would it be? Strip everything else. Lead with that one thing.
- Create a knowledge gap. Instead of stating the answer, ask the question first. Make the listener aware of something they do not know. Let them feel the gap before you fill it. Curiosity sustains attention.
- Make it concrete. Replace every abstraction with a specific example, image, or scenario. “Families in poverty” becomes “Maria, a single mother of three, who earns $12 per hour.” The specific is memorable; the abstract is not.
- Use the unexpected detail for credibility. Include one specific, surprising fact or detail that signals genuine knowledge. Internal credibility from surprising specifics often persuades more reliably than external authority.
- Connect to identity, not just interest. Frame the message in terms of who the listener is or aspires to be, not just what they want. “You are the kind of person who…” is more powerful than “here is why this is good for you.”
- Tell the story. Find the person whose experience embodies the idea you are communicating. Tell their story. The abstract principle, embodied in a specific narrative, will be remembered and shared. The principle alone will not.
Books Similar to Made to Stick
Switch by the same authors applies similar principles to behavior change rather than communication. Influence by Robert Cialdini examines the psychological principles that make persuasion and compliance more likely — overlapping territory with the credibility and emotion principles in Made to Stick. Talk Like TED by Carmine Gallo analyzes the structural and delivery techniques of the most effective TED talks through a lens similar to SUCCESs. Building a StoryBrand by Donald Miller applies storytelling principles specifically to business marketing communications.
Who Should Read Made to Stick
Everyone who communicates ideas with the intention of being remembered or prompting action. Leaders trying to align organizations around strategy. Teachers trying to make concepts stick with students. Marketers trying to create messages that cut through noise. Writers trying to make complex ideas accessible. Parents trying to pass on values to children. The framework is universal enough to apply in any communication context.
Integration: Making It Stick
The most immediate application of this book is to any presentation, document, or communication being prepared right now. Take it through the SUCCESs checklist: has it been stripped to its core? Has a knowledge gap been created that builds curiosity before it gets filled? Have abstractions been replaced with concrete specifics? Has an unexpected detail been included that signals genuine knowledge? Has it been connected to the listener’s identity? Has at least one story been told? Most professional communication fails all six. Fixing any two or three produces dramatic improvement in retention and action.
The deeper integration is developing the habit of concrete thinking — automatically translating abstract ideas into specific examples, scenarios, and stories before communicating them. This requires practice, because the Curse of Knowledge is persistent: communication keeps happening at the abstraction level thought happens at, which is the level appropriate for the expert’s own expertise, not the audience’s knowledge. The SUCCESs framework is a checklist to use after drafting, to force the translation from expert abstraction to concrete communication.
FAQ
What is the Curse of Knowledge and why does it matter? The cognitive inability to imagine what it’s like to not know something you know. Once a subject’s been mastered, the knowledge changes how it gets experienced — processed in abstract structures incomprehensible to someone encountering it for the first time. Communication happens at expertise rather than the level of the audience’s knowledge, producing messages clear to the speaker and opaque to everyone else. Recognizing the curse is the first step to overcoming it.
Can sticky ideas be used for manipulation? Yes, and the Heaths acknowledge this explicitly. The same principles that make beneficial ideas sticky make harmful ones sticky. The SUCCESs framework is a neutral communication technology. Its ethical application depends on the honesty and intent of the communicator. Propaganda and advertising have used these principles for decades; the book provides the analytical framework to recognize them when used against you, as well as to apply them yourself.
Which of the six principles is most important? The Heaths argue Simple and Stories are the most powerful, but all six interact — a story is more powerful when it’s also unexpected and concrete. The Curse of Knowledge affects all six: it produces vague abstractions (violates Simple and Concrete), predictable presentations (violates Unexpected), and messages that assume the listener’s emotional connection rather than establishing it (violates Emotional). Addressing the Curse of Knowledge first improves all six dimensions simultaneously.
The Curse of Knowledge in Professional Contexts
The Curse of Knowledge deserves extended treatment because it isn’t just a communication problem — it’s a systematic cognitive failure affecting every expert in every field, producing predictable communication failures that compound over time. Understanding the mechanism at depth is what allows the design of reliable countermeasures rather than just trying to remember to “communicate more clearly.”
The Curse operates through knowledge anchoring: knowing something anchors your mental simulation of what someone else experiences encountering that knowledge to your own knowing-state rather than their not-knowing-state. You read your own communication as someone who already knows what it says. It reads as clear because you know what it means. Your audience reads it without knowing what it means, and finds it opaque. The gap between the two readings is invisible to you, because you can’t step outside your own knowledge to simulate genuine ignorance of it.
Research by Elizabeth Newton at Stanford demonstrated the mechanism vividly: people asked to tap out the rhythm of well-known songs predicted that 50% of listeners would correctly identify the song from the tapping. The actual identification rate was 2.5%. The tappers could “hear” the full song in their heads while tapping — the melody was so well-known to them the rhythm felt like an obvious representation of it. The listeners heard only taps, with no access to the melody the tappers were imagining. The tappers dramatically overestimated how much information they were communicating because they were anchored to the full richness of the information in their own heads.
The practical countermeasure isn’t remembering to be clear. It’s testing communication on people who have genuine not-knowing status. Before any important communication, test it on someone who knows nothing about the topic. Not to dumb it down to their level, but to identify the specific places where knowledge-anchored assumptions are producing gaps invisible from inside the knowing-state. Every place the test reader gets confused is a place where an assumption about shared knowledge doesn’t hold. Fix those specific places. Repeat until the test reader can accurately summarize what got communicated. Then the Curse has been broken, at least for that specific communication.
The Mystery Structure and Narrative Engagement
The Heaths’ prescription for the “Unexpected” principle — raise the question before providing the answer, create the gap before filling it — deserves practical elaboration because it runs counter to how most professional communication gets taught. Standard business communication training teaches the “inverted pyramid”: lead with the conclusion, then provide the supporting evidence. This structure serves skimming readers who need the clinical takeaway quickly. It’s suboptimal for communication that needs to stick.
The mystery structure inverts this: create a compelling question the audience genuinely wants answered, withhold the answer long enough to let curiosity build, then deliver the answer in a way that resolves the tension the mystery created. This structure engages precisely because it exploits the brain’s natural drive to close knowledge gaps. Once a question is actively in mind, there’s a cognitive discomfort until it’s answered. That discomfort is attention paid to the content by the audience’s own cognitive machinery, at no additional effort to the communicator.
The structure appears throughout the best explanatory writing. A chapter opening “Scientists were baffled when they discovered that X was happening, because everything they knew said Y should happen instead” engages the reader’s curiosity before offering the explanation. A presentation opening “Last year, we did everything right — and still lost the deal. Here’s what we learned about why” creates a mystery the audience is motivated to see resolved. A product description opening “Most products in this category claim to solve X, but they all have the same hidden flaw” creates a knowledge gap the audience wants filled before the solution gets introduced.
The mystery structure works for internal communication as well as external. A memo leading with “I need to propose a significant change to our process. Before I explain what the change is, let me show you the problem that drove me to it” gets read more carefully and retained more reliably than a memo leading with “I recommend changing the process as follows.” The recommendation is the same. The engagement structure is fundamentally different. The Unexpected principle says: wanting people to remember the answer means making them curious about the question first.
The Scale from Abstract to Concrete
The Concrete principle is the one most professionals violate most consistently, and the violation almost always runs the same direction: too abstract, not concrete enough. The tendency toward abstraction gets reinforced by professional training — academics, lawyers, consultants, and managers all get rewarded for speaking at abstraction appropriate to their expertise, which is the level at which their audience can’t follow without shared expertise. The result is communication that impresses peers and confuses everyone else.
The Heaths provide a practical test: put any piece of communication on the “abstraction ladder.” At the bottom sit the most concrete, sensory-specific descriptions — the specific person, the specific moment, the specific action with specific details that can be visualized. At the top sit the most abstract, general category-level descriptions — “effective leadership,” “value creation,” “systematic risk.” Good communication moves fluidly between levels of the ladder, using concrete specifics to anchor abstract points and abstract categories to generalize the meaning of specific examples. Most professional communication lives exclusively at the top of the ladder and never comes down to the sensory-specific level where memory forms.
The prescription is spending more time at the bottom of the ladder — not exclusively there, but more than feels comfortable. For every abstract point, ask: what’s the specific example that instantiates this? What’s the concrete case that demonstrates this principle? Who’s the specific person whose experience embodies this idea? Then lead with the concrete case and derive the abstract principle from it, rather than stating the abstract principle and offering the concrete case as optional illustration. The concrete case is more memorable. The abstract principle derived from the concrete case is more durable than the abstract principle stated without grounding. The Heaths are correct that this is the difference between ideas that stick and ideas that disappear — and their own book is executed according to this prescription throughout.
Emotion and the WIIFM Principle in Depth
The Emotional principle is where most professionals are most uncomfortable, because emotional appeals feel manipulative to people trained in analytical disciplines. The Heaths carefully distinguish legitimate emotional connection from manipulation: legitimate emotional engagement connects the message to things the audience genuinely cares about, accurately representing the relationship between the message and those things. Manipulation creates false emotional connections to things the audience cares about in order to bypass their critical evaluation. The distinction is in accuracy, not in the presence of emotional engagement.
The research finding most professionals need to hear is that emotional engagement isn’t optional if the goal is people acting on the communication. It’s a prerequisite. Daniel Kahneman’s research on decision-making under uncertainty establishes that emotional valence is required for decisions to be made at all — people with damage to emotional processing areas of the brain can analyze decisions perfectly but can’t make them, because the emotional signal that says “this option feels right” is absent. Emotional engagement isn’t a nice-to-have for important communications. It’s the mechanism through which the audience converts understanding into action.
The WIIFM (“what’s in it for me?”) question is the most basic form of the Emotional principle, but the Heaths correctly identify it as insufficient for the most powerful emotional engagement. Self-interest is motivating but somewhat mechanical. Identity is more powerful: “what kind of person does this action make me?” The teenager who doesn’t care about their own long-term health cares enormously about being seen as rebellious against corporate manipulation. The employee unmoved by the business case for a new process cares about being the kind of colleague who helps their team succeed. The voter who tunes out policy arguments gets moved by the story of a specific person affected by the policy. Finding the emotional hook that connects communication to an audience’s genuine self-concept and deepest aspirations is the highest form of the Emotional principle — and the level at which the most memorable, most influential communication consistently operates.
Stories as Simulation Machines
The research on narrative processing the Heaths draw on explains why stories aren’t just more engaging than statistics — they get processed by the brain differently and stored more durably. When people read a narrative, they mentally simulate the experiences of the characters — activating the same brain regions that would activate from actually experiencing what the characters experience. The story isn’t just information about an experience. It’s a simulation of the experience itself, creating something closer to experiential memory than propositional memory.
This neural simulation explains why the stories people read and hear shape behavior in ways abstract principles stated directly don’t. The soldier who’s read and simulated hundreds of military narratives brings different intuitions to tactical decisions than one who’s only studied tactical doctrine. The nurse who’s heard dozens of patient stories brings different sensitivity to patient communication than one who’s only studied clinical protocols. The entrepreneur who’s absorbed dozens of startup narratives has pattern recognition about early-stage company dynamics that no amount of business school case study analysis fully replicates. Stories are the mechanism through which vicarious experience gets encoded and made available for future application.
For communicators, the implication isn’t “tell more stories” in a superficial sense. It’s identifying the specific human experience that best simulates the understanding the audience needs to gain, and telling that story with enough specificity, character development, and narrative tension to fully engage the mental simulation process. A story told in generic terms — “a company faced a challenge and overcame it” — doesn’t produce meaningful simulation. A story told in specific terms — “Maria, the operations director, received the call at 3am on a Tuesday and had forty-eight hours to prevent a $12 million client from walking” — engages simulation because the specificity lets the audience mentally inhabit the situation. The SUCCESs framework’s Concrete and Story principles work together at exactly this level: concrete specificity enables the narrative simulation that makes stories powerful as communication and memory tools.
Applying SUCCESs to Your Next Communication
The most valuable way to use the SUCCESs framework is as a post-draft checklist rather than a pre-draft constraint. Write what’s known first, then run the checklist. Simple: what’s the single most important thing, and is it leading the communication? Unexpected: does the opening create curiosity before providing the answer? Concrete: is every abstract claim grounded in a specific example or case? Credible: does the communication include specific, unexpected details that signal genuine knowledge? Emotional: has the audience’s genuine interest been explicitly identified and connected to the message? Stories: is there at least one person whose experience embodies the core message?
Most professional communication fails at Simple (too many equally important points), Unexpected (leading with the conclusion rather than the question), and Concrete (operating at too high a level of abstraction). Fixing these three, consistently, in every important communication produced, will produce dramatic improvements in whether ideas get remembered and acted on. The Heaths have given both the diagnosis and the prescription. The remaining variable is whether they get applied with the discipline effective communication actually requires — which means revising, testing on people who lack the relevant expertise, and accepting that a communication style optimized for impressing experts is systematically wrong for reaching and moving everyone else.
