I spent the spring of last year inside the archives of an institution that no longer exists. The building still stands — a brutalist monolith on the edge of what was once the capital — but the people who understood its cataloguing system retired, died, or were reassigned two reorganisations ago. Nobody knows what is in Room Fourteen.
The Half-Life of Institutional Memory
Organisations forget at a predictable rate. My research across fourteen public agencies found that critical operational knowledge — the kind that prevents infrastructure collapse or fiscal catastrophe — decays by roughly half every seven years. The median tenure of a senior civil servant in the same period: four years and three months. The numbers do not reconcile.
“The maps were not lost. They were simply drawn in a language nobody still speaks.”
I found the original zoning surveys for the old port district in a rusted filing cabinet on the fourth floor. They had been misfiled under a classification code that was retired in 1983. The paper was brittle but legible. Every flood-wall specification, every load-bearing calculation, every elevation contour — all of it intact, all of it inaccessible to the engineers who are currently redesigning that shoreline from scratch, at a cost of three hundred million over six years.
