Assess Evidence
What evidence exists? Rate each piece as strong, moderate, or weak. Note gaps.
Generate Hypotheses
Develop at least 3 possible explanations or solutions. Include one unconventional option.
Evaluate Systematically
Test each hypothesis against the evidence. What are the trade-offs? What are the risks?
