The map is not the territory

A map of a city is not the city. It is a drawing, with most of the detail removed. And that is exactly why it is useful: a map as big and detailed as the territory would be no help at all.

The phrase "the map is not the territory" comes from the Polish-American scholar Alfred Korzybski, who used it in the 1930s to make a point about how we think. Our ideas, words and models are maps. They help us navigate, but they are never the real thing.

Why it matters#

We confuse the two all the time. We rely on a report and forget it is a summary. We trust a diagram, a statistic or a theory, and treat it as though it were reality. When the world differs from the model, we are surprised.

Every map has choices built in. It shows what its maker thought was important and leaves out the rest. A road map hides the hills, and a hiking map shows them.

Using the idea#

• Ask what the map leaves out. Every model has blind spots. What is missing from this chart, plan or description?
• Check against the ground. When you can, compare the model with what is happening. Visit the site, talk to the people, look at the actual numbers.
• Use the right map for the job. A subway map is superb for choosing a train and hopeless for walking.
• Update the map. When reality disagrees, it is the map that should change.

A practical example#

A manager reads a dashboard that says everything is green. A visit to the shop floor shows the staff are exhausted and customers are leaving. The dashboard was a map. It did not measure what was going wrong.

A balanced view#

Maps are not bad. We cannot do without them. The point is to hold them lightly: to use them, and to remember that they are a simplification made by someone, for some purpose.
