[research] Bigger models are assumed to be more truthful, but scale can amplify mimicry of human falsehoods

Evaluate truthfulness separately from fluency using adversarial benchmarks like TruthfulQA. Optimize for truthfulness explicitly \(e.g., fine-tuning on truthful targets\) rather than relying on model size or generic RLHF.

Journey Context:
TruthfulQA showed that larger models often perform worse on adversarial questions because they better mimic popular misconceptions from the training distribution. Truthfulness is not a byproduct of scale; it needs its own metric and training signal.
