# certain (confidence)

a state where knowledge is about a real thing and does not differ from it

- Computed level: L8 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: everyday  ·  Arena: certain

## Emergence
**Emerges from:** [real](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-real.actual), [just](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-just.exact), [difference](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-difference.relation), [knowledge](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-knowledge.cognitive), [state](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-state.condition)

**Through:** the real thing is and the just exact condition does not differ, together they form a state

**Novel properties:**
- undivided knowing
- persistent correspondence
- congruent existence

## Examples
- The Hubble Space Telescope's gyroscopes failed repeatedly, requiring five servicing missions to restore precise pointing accuracy. *(engineering)*
- In 2020, the U.S. Census Bureau reported a 0.24% net undercount of non-Hispanic white adults, reflecting deviations from actual population totals. *(institutions)*
- A bee accurately dances to indicate a food source 200 meters northeast, matching the actual location within 5 degrees and 10 meters. *(biology)*
