Secrets

There are still secrets: things that are true and important and that almost no one has noticed.

The reason most people stop looking is that the search for secrets has been culturally devalued. The schools teach received knowledge; the careers reward executing on existing models; the professional incentives favor consensus over contrarian conviction. Anyone who claims to have spotted a secret is socially expected to be wrong and is treated accordingly until the secret becomes obvious to everyone.

Thiel's argument is that the discovery of secrets is the act zero-to-one progress requires. The Apple insight that the right computer was a personal one. The Google insight that the right search algorithm was link-analysis. The Uber insight that taxi dispatch was solvable with smartphones. Each was a secret that almost no one was looking for, then a secret that almost no one believed, then a secret only the founders pursued long enough to prove. The pattern repeats.

The practical move is to actively look for secrets in domains you know well. What is true that almost no one in this field agrees with? What would need to be true for that thing to obvious in ten years? The questions are uncomfortable because they require you to disagree with the consensus, but the secrets only stay secret while the consensus is wrong.

Thiel defines secrets as important truths that very few people know — the territory between mundane conventions that everyone already understands and impossible mysteries that no one can solve. He argues that the prevailing cultural belief that all the big discoveries have been made, leaving only incremental refinement, is simply false: there are still many secrets, things that are true, important, and almost entirely unnoticed. He diagnoses four reasons people have stopped looking — incrementalism drilled in by schooling, risk-aversion that punishes being wrong about big things, complacency that assumes everything worth knowing is known, and 'flatness,' the assumption that in a global, efficient world any available opportunity would already have been taken by someone. Yet great companies are precisely the ones founded on a secret, which comes in two kinds: secrets about nature, which become new technologies, and secrets about people — things they hide, or do not know about themselves, which become new businesses. The contrarian interview question from the opening chapter is, in effect, the disciplined search for secrets. And once you find one, Thiel advises telling only the people you must, because the right response to a genuine secret is not to publish it but to build a company that quietly exploits it before the rest of the world catches on.

What the chapter means, in one line: a secret is something true and important that almost nobody believes yet, and a start-up worth building usually starts from one. Thiel places secrets between two other kinds of knowledge. Conventions are true things everyone already knows, so there is no advantage in them. Mysteries are things nobody can work out, so there is no point waiting on them. Secrets sit in between: hard to see, but possible to find with work.

How to look for one. Thiel splits secrets into two kinds and gives each a question. Secrets about nature ask: what is the physical world not telling you? Those become new technologies. Secrets about people ask: what are people not telling you, or not admitting to themselves? Those become new businesses, because they point at a need nobody is serving. In practice the search is the same as the contrarian question from Chapter 1, aimed at one field you know well: what do you see there that the people around you would call wrong? The four habits the chapter blames for people giving up the search (incrementalism, risk aversion, complacency and the belief that the world is flat and efficient) work as a checklist. If your idea sounds strange for one of those four reasons, that is not a reason to drop it.

What to do once you have one, and where the idea goes wrong. Thiel's advice is to tell only the people you need, such as co-founders and early staff, because a secret is an advantage only while it stays one. The weak spot is that a secret and a mistake look the same from the inside: both are things almost nobody agrees with you on. The chapter's answer is to test the belief by building, which is the subject of Chapter 9, Foundations. It follows Chapter 7, Follow the Money, and connects back to Chapter 6, You Are Not a Lottery Ticket, where Thiel argues that a definite plan beats waiting for luck.
