A new research paper explores how typed decision models, used for classification and routing tasks, prioritize labels over definitions. The study found that across multiple models and tasks, the models predominantly relied on the provided labels, even when they contradicted the detailed definitions. This "option-label bias" was so strong that removing definitions entirely did not significantly impact accuracy, while renaming options to generic labels like 'A' and 'B' improved performance. The research suggests this bias stems from prompt rendering rather than the model's decision head, and offers a test for practitioners to identify this behavior in their own models. AI
