| Challenge: | Specifically, we examine when the LLMs’ answer is (pre)determined, especially before the CoT begins or after, and how strongly the information from CoT specifically has a causal effect on the final answer. |
| Approach: | They examine when the LLMs’ answer is (pre)determined, especially before the CoT begins or after, and how strongly the information from CoT specifically has a causal effect on the final answer. |
| Outcome: | The proposed model can generate reasoning chains while generating the reasoning chain on the fly. |

| Challenge: | Explicit multi-step reasoning is widely adopted to improve the performance of language models. |
| Approach: | They propose a systematic reasoning strategy that LMs use to solve multi-step reasoning tasks. |
| Outcome: | The proposed strategy improves the performance of language models by combining heuristics with rational strategies. |
