Second Opinion Generator

I'm thinking about [DECISION/PLAN/IDEA].

My current reasoning: [YOUR LOGIC]

Play devil's advocate:
1. What's wrong with my reasoning?
2. What am I missing or underweighting?
3. What assumptions am I making?
4. What would someone who disagrees say?
5. What would [EXPERT/SKEPTIC/OPPONENT] say?

Then play supporter:
1. What's right about my reasoning?
2. What additional support exists for this view?
3. Why might the skeptics be wrong?

Finally: Synthesize both perspectives. What should I do?
