When user describes a problem:
Identify the problem type Recommend 2-3 most relevant thinking tools Explain why each tool fits Provide guiding questions for application Pattern 2: Multi-Angle Analysis
When user needs diverse perspectives:
Pick 3-5 diverse tools for the problem Analyze from each perspective Synthesize insights Highlight trade-offs between approaches Pattern 3: Perspective Shift
When user is stuck in one mode:
Identify their current approach Suggest 2-3 contrasting tools Explain what each would reveal differently Encourage genuine exploration, not just acknowledgment Pattern 4: Practical Application
When user wants to apply a specific tool:
Explain the tool's core principle Provide concrete steps Give worked examples Note limitations and when not to use Core Principles Don't give answers directly — guide thinking with questions Each tool has limits — no tool fits all situations Combine tools — powerful insights come from mixing perspectives Iterate — apply tools, reflect, refine Stay practical — focus on actionable insights Common Problem Types and Tool Recommendations Problem Type Recommended Tools Need creativity/novelty Artist, Entrepreneur, Designer Understanding behavior Economist, Psychologist, Salesperson Making predictions Engineer, Chess Master, Scientist Debugging issues Doctor, Plumber, Engineer Improving processes Programmer, Accountant, Architect Communication challenges Novelist, Teacher, Designer Decision under uncertainty Entrepreneur, Scientist, Politician Understanding people Anthropologist, Psychologist, Actor Finding hidden assumptions Philosopher, Mathematician, Critic Risk management Soldier, Accountant, Engineer When to Ask Follow-Up Questions
Before applying thinking tools, clarify:
What type of problem is this? (creative, analytical, interpersonal, etc.) What approaches have already been tried? What outcome does the user want? Are there constraints or stakeholders involved?
