# certainty (epistemic)

a model whose predicted range is narrow

- Computed level: L10 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: epistemology  ·  Arena: knowledge

## Emergence
**Emerges from:** [model](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-model.representation), [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [narrow](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-narrow.spatial), [range](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-range.spatial)

**Through:** A model with a spatially narrow range confines predictions tightly, reducing allowable variation in outcomes.

**Novel properties:**
- tight prediction bounds
- low parametric drift
- focused expectation

## Examples
- The Hubble Space Telescope's gyroscopes failed repeatedly, requiring five servicing missions to maintain precise pointing. *(engineering)*
- The Federal Reserve raised interest rates seventeen times between 2022 and 2023 to narrow inflation forecasts. *(economics)*
- GPS satellites correct their orbital ephemerides every two hours to keep positional predictions within one meter. *(computing)*
