Self-consistency means running the same prompt multiple times and selecting the most common or best answer — reduces variance on tricky questions.

How to Use It

• Run the same prompt 3–5 times
• Compare outputs and look for consensus
• Or ask in one prompt: "Give me 3 different approaches to this problem, then tell me which is best and why"

Best For

• High-stakes decisions where one answer isn't enough
• Creative tasks where you want variety before choosing
• Fact-checking uncertain claims
