# moderation (central)

position near the centre of a parameter's window, where drift does not change what persists

- Computed level: L13 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window ontology  ·  Arena: abstract

## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [centre](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-centre.location), [persist](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-persist.continue), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [near](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-near.spatial), [position](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-position.spatial)

**Through:** The components together define a stable position within a parameter's range where random drift does not alter the persistence of a thing.

**Novel properties:**
- central stability
- drift resilience
- persistence maintenance

## Examples
- The thermostat in a NASA Apollo 13 cabin maintained 21°C despite power failure, using backup systems until re-entry. *(engineering)*
- The human body keeps blood pH at 7.4 through kidney and lung adjustments, even during intense exercise. *(biology)*
- The Federal Reserve adjusted interest rates between 2% and 3% from 2018–2019 to stabilize inflation near 2.1%. *(economics)*
