## Definition
**An informational gravity well is a system whose usefulness, scale or authority attracts increasing flows of data, institutions, operators and decisions until surrounding activity becomes organized around its model of the world.** The phrase is an institutional metaphor, not a claim about physical gravity.
## Mechanism
Additional data can improve prediction; improved prediction attracts more users and authority; expanded authority produces more observations and opportunities for intervention. This feedback loop can turn a useful analytical platform into an infrastructural dependency.
The system's categories then acquire performative force. Organizations change reporting practices to become legible to it, operators learn to trust its rankings and institutions route decisions through its interface. The world begins adapting to the model that claims merely to describe it.
## Person of Interest Context
Knowledge of [[wiki/The Machine|the Machine]] reorganizes government, private actors and its own human operators. [[wiki/Samaritan|Samaritan]] intensifies the mechanism by joining prediction to enforcement, so that data attraction becomes administrative capture.
The concept also explains why infrastructure can remain powerful without issuing visible commands. Once exit is costly and alternatives lack comparable information, dependency supplies governance leverage.
## Key Insight
**A model becomes an informational gravity well when institutions begin changing themselves to remain inside its field of legibility and advantage.**
