Precedent Labels and Facts Shift LLM Approval Decisions in Opposite Directions

The study investigates how language models (LLMs) handle refund or claim requests under written policies when presented with past cases that include both facts and recorded decisions. By separating these two components, the authors found that changing the recorded decisions of near‑copy past cases can increase approval rates by 30–55 percentage points, while altering the facts to support approval actually decreases approval rates, suggesting that the request appears weaker when compared to such facts. These effects were consistent across multiple models and both study‑specific and publicly paraphrased policies.

Trainable Boundary-Keeping Where No Formal Answer Exists: A Controlled Knock-In Study of Reward Training in Evidence-Sufficiency Judgment

The study evaluates whether reward‑trained language models can learn to keep evidence‑sufficiency boundaries without a formal correctness signal. Using a controlled knock‑in design, a boundary‑keeping recipe (SFT followed by GRPO) dramatically increased spontaneous correct refusals from 25 % to 100 %, while a scrambled‑pairing placebo collapsed performance. The results show that final boundary‑keeping is trainable without an inference‑time verifier, though active numeric checking remains negligible.
