Self-Consistency
Domain: Prompt Engineering
π― Motivation
Run the same CoT prompt multiple times and take the majority answer. If most runs agree, the answer is more likely correct.
π Concrete Example
Ask βWhat is 17 x 23?β 5 times with CoT. Results: 391, 391, 391, 392, 391. Majority is 391. The one 392 is likely an error. Self-consistency filters it out.
π Analogy
Asking 5 classmates to solve a math problem independently - if 4 say β391β and 1 says β392β, you trust 391. The majority vote (self-consistency) is more reliable than any single answer.
