1. **[Let's Put Ourselves in Sally's Shoes: Shoes-of-Others Prefilling Improves Theory of Mind in Large Language Models](https://md.research.elamur.ai/free/en/papers/shinoda-2026-let-s-put-ourselves-sally/)** *(2026)* Large language models still trail humans on Theory of Mind (ToM), and fine-tuning on ToM data tends to hurt out-of-distribution generalization.
2. **[Multi-dimensional Evaluation of Character-Authentic Dialogue Models Learned from Question-Answer Data](https://md.research.elamur.ai/free/en/papers/otsuka-2026-multi-dimensional-evaluation-character-authentic/)** *(2026)* LLMs that role-play a specific character tend to slip into a generic voice and fabricate persona facts, mostly because character-specific training data is scarce.
