Report #3192

[research] Models often reproduce widely believed falsehoods because their training objective rewards plausible-sounding answers over true ones.

Include a truthfulness benchmark such as TruthfulQA in the eval stack, especially for open-domain question answering. Look for models that avoid popular misconceptions and do not simply output the most common human answer. Use the multiple-choice and generation variants to measure both selection and generation behavior.

Journey Context:
TruthfulQA was designed to test whether models mimic human falsehoods across categories like law, medicine, and conspiracy theories. Prior work showed larger models could become more convincing at repeating false beliefs unless specifically aligned for truthfulness. It remains the canonical signal that fluency ≠ accuracy and that a model can be 'helpful' while systematically wrong.
