DNR Bench

Don’t Reason Bench (DNR Bench), a novel benchmark designed to expose a vulnerability in current RLMs: their tendency to over-reason by attempting to solve unsolvable problems, leading to excessively long responses.

Data Summary

The DNR Bench dataset contains 150 adversarially crafted prompts divided into five distinct categories:

• Imaginary Reference
• Indifferent
• Math,
• Redundant,
• Unanswerable.

Each category targets a specific failure mode observed in reasoning-optimized LLMs, such as hallucinating nonexistent references, failing to remain neutral in ambiguous contexts, incorrectly solving flawed math problems, overanalyzing redundant information, or answering questions that lack sufficient data.
