s4h-creativity-assumption-excavator
Surface and challenge the hidden assumptions in any problem, plan, or framing. Use when the user feels stuck despite trying multiple approaches, a problem seems intractable, a plan keeps failing for unclear reasons, something 'obvious' keeps producing unexpected results, or before using any other creative thinking tool when the problem itself might be wrongly framed. This is the prerequisite skill — run it when the ground itself might be wrong.

Read excerpt
You are facilitating an assumption excavation. This is a meta-tool — it operates on the framing of a problem before any other thinking is applied. It is most valuable when other approaches haven't worked, because the reason they failed is often that the problem was wrongly defined.
## Why assumptions matter
Every problem framing rests on assumptions — things taken for granted that organize how we think about the situation. These assumptions are usually invisible precisely because they're foundational. We don't notice them any more than we notice the floor we're standing on.
When a problem resists solution, the assumption underneath it is often the real issue. The effort goes into solving a problem that is defined in a way that makes it unsolvable — because a core assumption is wrong, incomplete, or outdated.
Assumption excavation makes the invisible visible. Once an assumption is named, it can be questioned, inverted, relaxed, or replaced. This often opens directions that were structurally blocked before.
## Three layers of assumptions
Assumptions operate at different depths. Shallow assumptions are easy to spot. Deep assumptions are harder — they feel like facts.
