Made to Stick

The Heaths' question is not what makes an idea true or good but what makes it survive transmission. Urban legends and proverbs spread without any budget; carefully prepared corporate messages do not survive the lift back to the desk.

Their answer is six principles, and their claim is that stickiness is a property of how an idea is constructed rather than of the talent of whoever is communicating it.

The question is not whether an idea is good. It is whether it survives being retold by someone who half-remembers it.

The book's most valuable single concept, and the reason for everything else in it. Once you know something, you cannot easily imagine not knowing it, and you systematically overestimate how much of your meaning is reaching other people.

The Heaths present it as the central villain: experts do not communicate badly through carelessness but because their knowledge has made the gaps invisible to them. Every one of the six principles is a workaround for this one problem.

Simple here means finding the core — the single most important thing — and being ruthless about it, not dumbing down. Their standard is the proverb: a short statement carrying a deep idea.

The hardest part is what they call the inverted pyramid discipline: leading with the most important thing and accepting that everything after it may not be read. Most organisational communication fails here by refusing to rank.

Attention is captured by breaking a pattern, and held by opening a gap in someone's knowledge that they now want closed.

The Heaths' most actionable advice is to identify the counter-intuitive element of your message and lead with it, then close the gap you opened. Their warning is equally useful: surprise that is merely gimmicky spends attention without buying anything.

The principle most violated in professional settings. Abstract language is the natural output of expertise, and it is nearly unmemorable — concrete detail is what lets two people be sure they mean the same thing.

Their test is whether the idea can be examined with the senses. "World-class customer service" is abstract; a specific thing an employee actually did is concrete, and only one of them will be retold.

If two people cannot picture the same thing, they have not yet agreed about anything.

Credibility rarely comes from statistics, which are hard to hold and easy to dispute. The Heaths catalogue what works better: authority and anti-authority sources, vivid detail that implies first-hand knowledge, human-scale statistics, and testable claims the audience can check themselves.

Their advice on numbers is the most immediately useful: put a statistic in a form a person can feel, since a number nobody can picture communicates nothing regardless of its accuracy.

People care about people rather than about abstractions, and the Heaths argue that the most reliable route to feeling is the concrete individual rather than the aggregate.

For stories they offer three plots that recur in ideas that spread — challenge, connection and creativity — and a practical note that matters: you are more often finding a story that already exists in your organisation than inventing one.

The framework is descriptive rather than predictive. SUCCESs is derived from examining ideas that already spread, which makes it vulnerable to survivorship: the ideas that had all six properties and vanished are not in the sample.

The acronym is also a little forced, and the book is longer than its argument requires — the core is delivered early and then illustrated at length, which is a common shape in the genre.

The Heaths note that stickiness is amoral: urban legends, conspiracy theories and successful propaganda all score well on these principles, which is precisely why they were studied.

The book does not dwell on this, and a reader should. The same six properties that make a true idea survive make a false one survive, and the techniques are considerably more effective in the hands of someone unconstrained by accuracy.

The Curse of Knowledge alone justifies the book. Knowing that expertise makes your own gaps invisible changes how you prepare anything for someone else.

Practically: find the core, lead with the counter-intuitive part, replace an abstraction with something a person can picture, and put every number into a form that can be felt. Those four cover most of the value.
