# chance (random)

drift with no feedback available that would determine its direction.

- Computed level: L15 (depth in the emergence graph, not abstraction)

## Emergence
**Emerges from:** [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [available](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-available.accessible), [direction](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-direction.spatial)

**Through:** The absence of available feedback that could guide it combines with aimless drift and an undefined direction to constitute chance as randomness.

**Novel properties:**
- undirected variation
- uninformed drift
- unconstrained change

## Examples
- Cosmic microwave background radiation shows a near-uniform temperature of 2.7 K across the sky, with minute fluctuations from quantum fluctuations in the early universe. *(physics)*
- The genetic makeup of the Tristan da Cunha island population includes a high incidence of asthma due to the founder effect from a small number of settlers. *(biology)*
- Bitcoin’s proof-of-work system adjusts mining difficulty every 2016 blocks to maintain a 10-minute average block time despite fluctuating network hash rates. *(computing)*
