[research] Relying on a single greedy-decoded Chain-of-Thought for factual/mathematical queries, which is highly susceptible to initial token sampling variance

Sample multiple reasoning paths \(temperature > 0\) and take the majority vote on the final answer, rather than the reasoning trace.

Journey Context:
Greedy decoding is brittle; a single wrong token early in the reasoning trace derails the entire factual derivation. Self-consistency leverages the intuition that the correct answer is reachable via multiple valid reasoning paths, while hallucinated answers are scattered. It significantly improves factuality on arithmetic and factual lookup without requiring model retraining, at the cost of compute.
