Definition
The map is not the territory. A map is useful precisely because it leaves things out — it compresses a complex landscape into something you can hold and read. But that same compression means the map can never be the place itself.
This idea, drawn from the work of Alfred Korzybski, applies to every model, theory, statistic, or summary. Each is a representation, helpful for navigation but always partial, always potentially out of date, and always shaped by the maker's choices about what mattered enough to include.
Why it matters
How it works
To use this principle, treat any representation as a starting hypothesis rather than the final truth. Ask who made the map and why, what it leaves out, and how recently it was drawn. When the territory pushes back — when results contradict the plan — trust the territory and redraw the map.
The goal is not to abandon maps, since reasoning without them is impossible, but to keep checking them against direct contact with reality.
