Assumption Excavation

I believe [statement of belief]. Help me excavate the assumptions underneath this belief.

MY REASONING:
[How you arrived at this belief]

EXCAVATION PROCESS:
1. Identify every assumption my belief depends on—both obvious and hidden
2. For each assumption:
   - Is this empirically testable or a value judgment?
   - What's the evidence for and against?
   - What would falsify it?
   - How critical is it? (If wrong, does my conclusion survive?)

3. Identify which assumptions I'm probably unaware I'm making
4. Suggest what I should investigate to stress-test my belief
5. Offer your honest assessment of how well-founded this belief is

Be direct. I'd rather learn my reasoning is flawed than persist in error.
