## Description
Improve reasoning on specific, detail-heavy questions by first answering a strictly more abstract version of them — extracting the underlying principle, concept, or class of fact — and then applying that principle back to the specific case. Composes with K1, K5, S2, S6, V15. This is a condensed digest; the canonical file (`patterns/R19-Step-Back-Prompting.md`) carries the full decision criteria, failure modes, and implementation.

## Key points
- the question is specific and detail-heavy but rests on a generalisable concept, law, or class the model knows;
- a single CoT pass produces confident-but-wrong intermediate steps that ignore the relevant principle;
- the task domain has *named* principles or concepts (physics laws, legal doctrines, biological mechanisms, accounting standards) and a successful answer reduces to "apply principle X";
- the system has a retrieval layer and the abstract answer is more likely to be in the corpus than the specific answer.
