No improvement over zero-shot CoT
- CoT exemplars do not improve reasoning over zero-shot CoT on the Qwen2.5 series; their remaining function is output-format alignment. Injecting 50% noise into exemplars matched or slightly beat the clean baseline on Qwen2.5-72B, implying the model selectively ignores them. arXiv:2506.14641
