Island Gigantism
Updated 2026-08-15
INTRODUCTION
English translation pending.
CORE DEFINITION
Island gigantism is the evolutionary pattern in which small species grow large on isolated islands, the dodo and the giant tortoise being the standard examples, because predators and competitors are absent. As a model it is the curse-of-monopoly warning: a department inside a large company that lacks external competition becomes bloated, inefficient, and fragile, exactly like an island species, and introducing outside competition, importing the predator, is the only way to prevent the gigantism that ends in extinction.
SCAFFOLDING EFFECT
Reduce cognitive load
- Find the island units: identify which departments face no real external competition. - Import the predator: bring in outside benchmarks, rivals, or market pressure. - Measure fitness honestly: track the unit against the outside rather than against last year.
Anchor fast decisions
Selection pressure is what keeps a system trimmed to its environment, and on an island the pressures that discipline size and efficiency are simply absent, so bloat accumulates without cost until a shock arrives. The cost is deferred rather than avoided, which is why isolation feels safe right up to the moment it stops being safe.
