A new research paper from arXiv investigates potential data artifacts in synthetic corpora used for training reinforcement learning from human feedback (RLHF) models. The study specifically audits the GooseReason-0.7M dataset, which generates distractors by having language models invent incorrect answers around real human text. Researchers found that while a simple classifier could barely distinguish synthetic from real data, a more nuanced analysis revealed that code-based distractors were too similar to the correct answers by construction. Furthermore, an intervention experiment showed that training a policy on data with these artifacts did not yield better results than training on a control corpus, suggesting the artifact was unexploited under the given budget.
