# Domain Divergence
Scan and select maximally diverse source domains to maximize creative potential.
## Stages
### Stage 1: Domain Scanning
Use domain-scanning SOP to identify candidate source domains. Cast a wide net across sciences, arts, engineering, biology, social systems, mathematics, and everyday life.
### Stage 2: Random Paper Entry
Inject randomness via random-paper-entry SOP. Select papers from unexpected fields to break domain fixation and discover overlooked source domains.
### Stage 3: Random Word Stimulus
Use random-word-stimulus SOP to generate additional domain candidates that pure search would miss. Random words point to concrete domains (e.g., "coral" → marine biology → reef self-organization).
### Stage 4: Evaluate Diversity
Assess the collected domains for genuine diversity:
- No two domains should share the same parent discipline
- Domains should span at least 3 of: natural science, social science, engineering, arts, mathematics, everyday life
- Each domain must have identifiable transfer potential to the target problem
## Minimum Yield
| Metric | Floor |
|--------|-------|
| Domains scanned | ≥8 |
| Unrelated domains identified | ≥3 |
