[research] Treating factual recall confidence the same as logical/mathematical reasoning confidence

When calculating confidence thresholds for abstention, separate the task into 'retrieval' vs. 'reasoning'. For factual recall, rely on token probabilities; for reasoning, use self-consistency \(majority vote of multiple samples\).

Journey Context:
Models are often well-calibrated for factual recall \(high probability equals likely correct\) but poorly calibrated for reasoning \(a model can be highly confident in a flawed logical step\). Applying a single confidence threshold across both fails. Self-consistency \(generating N reasoning paths and taking the majority\) is a much better proxy for confidence in reasoning tasks than the raw token probability of the final answer.
