0123581321?☕
The Fibonacci sequence (1, 2, 3, 5, 8, 13…) grows so the gaps widen as numbers get bigger. That mirrors how uncertainty grows with size — it is easy to tell a 2 from a 3, but pointless to argue 20 versus 21.
Why it works
Because the steps are non-linear, teams round to a meaningful bucket instead of debating false precision.
