The Knowledge No One Holds

The idea in plain words

A tin mine somewhere closes, and the price of tin rises. Across the world, people who use tin start using less, substituting other materials, looking harder for supplies, and none of them needs to know why. The price has carried the essential information, that tin is now scarcer, to millions of people who could never have been told about the mine.

Friedrich Hayek used this kind of example to argue that the central problem of any economy, or any large organisation, is not how to allocate resources given the facts, but how to use facts that are scattered among many people and never available to any single mind. Michael Polanyi added a further twist: much of what people know cannot be stated at all. As he put it, “we can know more than we can tell.”

Where it comes from

Hayek wrote “The Use of Knowledge in Society” in 1945, during a long debate about whether a socialist planning board could allocate resources as well as a market. Planners imagined a central body gathering all the relevant data and computing the best plan. Hayek argued that this misunderstood the nature of the data. The most important knowledge is knowledge of the particular circumstances of time and place: the shipper who knows which ships are half-empty, the agent who knows which buildings are about to come free, the worker who knows the quirks of a particular machine. This knowledge is fleeting, local and dispersed. It cannot be collected into statistics without losing what makes it useful. The price system, Hayek argued, coordinates such knowledge without centralising it.

Gilbert Ryle had drawn a related distinction in 1949 between knowing that, factual knowledge that can be stated, and knowing how, the practical ability to do something. Knowing how to ride a bicycle is not a matter of knowing facts about balance.

Polanyi, a chemist turned philosopher, approached the same territory from the inside. In Personal Knowledge (1958) and The Tacit Dimension (1966) he argued that all knowledge rests on a tacit foundation. We recognise a face among thousands without being able to say how. A skilled diagnostician sees illness before she can name the signs. A craftsman knows when a joint is right. This tacit knowledge is learned by apprenticeship and practice rather than reading, and it cannot be fully transferred in words.

What it does to the mind

Senior decision-makers suffer from a particular illusion: that the information reaching them is the information that matters. Reports, dashboards and summaries are, by their nature, the parts of knowledge that can be written down and aggregated. Much of what is tacit and local has been stripped out on the way up. The higher the decision, the thinner the knowledge it rests on, while confidence often runs the other way.

People closest to the work, meanwhile, often cannot explain why they believe what they believe. When asked to justify a judgement, they produce reasons that sound weak, and the judgement is overruled by someone with a spreadsheet. The tacit knowledge was real; it simply could not compete in a format designed for explicit knowledge.

Where it shows up

Netflix’s culture deck, with its principle of “context, not control”, is an explicit attempt to push decisions to where knowledge sits. Amazon’s two-way doors do the same for reversible choices. Yegge’s Platforms Rant argues that a company’s parts should talk through interfaces, a kind of internal market, rather than central coordination. The note-taking essay asks how much knowledge can ever be captured in notes at all. In the blind case The Company That Invented Its Market, the reveal shows production drifting towards a new business through decisions made lower in the company, before the executives formally decided.

What it asks of someone deciding

Ask where the knowledge is before asking who should decide. If the relevant facts are local and fast-changing, central decisions will be slow and wrong.

Build channels for tacit knowledge: time with customers, apprenticeship, reviews where people show the work rather than summarise it. Some knowledge can only travel through people.

Keep central what must be central. Hayek’s point was not that nothing should be decided at the top, but that the top should set rules and signals, and let those with the knowledge act within them.
