A developer measured the effectiveness of self-verification in LLMs, finding that while it can improve precision, it often comes at the cost of reduced overall delivery rate. The key issue identified was the misuse of precision as a metric, which structurally cannot decrease when filtering is applied. A more accurate evaluation requires considering both precision and coverage, revealing that a fallible verifier can reject correct answers, leading to a worse overall performance in certain scenarios.
