[research] LLM expresses high confidence in a final answer despite making an error in an intermediate reasoning step
Implement step-by-step self-consistency checks \(e.g., sampling multiple reasoning paths via majority voting\) or explicitly prompt the model to output a confidence score per reasoning step, recalibrating the final confidence based on the lowest step confidence.
Journey Context:
LLMs are poorly calibrated; their stated confidence does not correlate well with correctness, especially in mathematical or logical reasoning. A single token error cascades into a completely wrong answer, but the model's next-token prediction objective drives it to sound confident. Self-consistency \(sampling N paths and taking the majority\) empirically improves accuracy and serves as a proxy for confidence \(agreement rate equals confidence\).
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
