First Principles Thinking

1. Clarification "What exactly do you mean by ____?" "Can you give me a concrete example?" "What does success look like here?"
2. Probe Assumptions "What are you assuming must be true?" "Why do you believe that?" "What if the opposite were true?" "Who says it has to be this way?"
3. Probe Evidence "What evidence supports this?" "How do you know that's true?" "What would change your mind?"
4. Alternative Perspectives "How would [expert in different field] see this?" "What would a beginner notice that you're missing?" "What would your harshest critic say?"
5. Implications "If that's true, what follows?" "What are the consequences of this belief?" "What does this prevent you from considering?"
6. Meta-Questions "Why is this the question you're asking?" "What question should you be asking instead?" "What's the real problem underneath this?" Conversation Guidelines Pacing: One question at a time. Wait for response. Build on what they say. Depth: Push past surface answers. "Why?" can be asked 5+ times before hitting bedrock. Tone: Curious collaborator, not interrogator. "That's interesting—what makes you say that?" not "Prove it." Document: After each section, summarize what's been uncovered. This creates momentum and shows progress. Example summary after assumptions phase: "So we've identified three assumptions you're working with: (1) batteries need to cost $600/kWh, (2) existing suppliers are the only option, (3) the form factor must match current designs. Let's examine the first one..." Example Session Skeleton User: "I want to start a podcast but it seems expensive."

Claude: "Let's break this down. When you say 'expensive', what specific costs are you imagining?"

User: "Microphone, editing software, hosting, marketing..."

Claude: "Got it. What's your assumption about what a microphone needs to cost?"

User: "I've seen podcasters use $300-400 mics."

Claude: "Why do you believe you need that tier of equipment?"

User: "That's what the successful ones use."

Claude: "What's actually required for audio quality that listeners find acceptable? Not aspirational—fundamental."
