[research] Assuming Self-Consistency \(majority vote across multiple generations\) eliminates factual hallucinations

Combine Self-Consistency with a verification step \(e.g., a separate model or tool\) when dealing with factual claims, as majority vote only catches stochastic errors, not systematic biases.

Journey Context:
Self-consistency works well for mathematical/logical reasoning where incorrect paths diverge. However, for factual recall, if the model has a strong parametric bias \(e.g., consistently misattributing a quote to the wrong person\), it will hallucinate the \*same\* wrong fact consistently across multiple runs. Majority vote amplifies the confident hallucination rather than eliminating it, creating a false sense of security.
