Lucretius Problem

INTRODUCTION
English translation pending.
CORE DEFINITION
Named after Lucretius, who observed that a fool takes the highest mountain he has seen for the highest in the world, the problem describes the tendency to bound future extremes by the largest event in the historical record. Because imagination is anchored to experience, risk models and infrastructure are often designed against the worst observed case. For complex systems with heavy-tailed distributions, the next event can exceed every previous one, so safety margins built on the record alone are insufficient.
SCAFFOLDING EFFECT
Reduce cognitive load
- Question the ceiling: ask whether your worst case is a true limit or only the largest so far. - Add a premium: place a margin above the historical maximum before designing defenses. - Stress the tail: test the plan against scenarios worse than anything recorded.
Anchor fast decisions
Estimates of the possible are drawn from memory, and memory contains only observed events, so the largest observation becomes the implicit upper bound. In heavy-tailed systems the probability of exceeding the historical maximum is not negligible, and the damage scales with the excess. Adding an explicit margin above the record restores the protection that the anchor removes.
