TL;DR

Chain-of-Thought (CoT) prompting remains effective even when the demonstrated rationales contain invalid reasoning, retaining over 80–90% of CoT performance under various metrics. The key factors for effective CoT are that rationales stay relevant to the query and that their steps are correctly ordered, rather than being logically valid.

Key findings

  • Invalid reasoning in demonstrations still yields high performance: on GSM8K with text-davinci-002, CoT reaches 48.3 Inter. F1 and 48.5 Answer Acc., while invalid reasoning reaches 43.9 Inter. F1 and 39.5 Answer Acc.; on Bamboogle, CoT reaches 45.2 Inter. Recall and 45.2 Answer F1, while invalid reasoning reaches 44.4 Inter. Recall and 39.4 Answer F1.
  • Relevance and coherence are key: the “no relevance” setting (both components irrelevant) underperforms standard prompting on GSM8K (11.0 Answer Acc. vs. 15.4 for STD), and “no coherence for language templates” drops to 28.3 Inter. F1 from CoT’s 48.3.
  • For bridging objects, relevance matters more than coherence: incoherent bridging objects achieve 39.2 Inter. F1 on GSM8K, while irrelevant bridging objects achieve 26.2 Inter. F1.
  • At the instance level, there are cases where CoT is wrong and invalid reasoning is correct: 62/196 for GSM8K and 6/20 for Bamboogle.

Methods

  • The authors run ablation experiments on two multi-step reasoning tasks: arithmetic reasoning on GSM8K (800 of 1319 test examples sampled) and multi-hop factual QA on Bamboogle (all 125 test samples).
  • Main backbone is InstructGPT-175B text-davinci-002 with greedy decoding; additional results are reported for text-davinci-003, PaLM, and Flan-PaLM in the appendix.
  • Ablations alter CoT rationales by invalid reasoning, destroying relevance or coherence of bridging objects and language templates, and combined no-relevance/no-coherence settings; evaluation includes extrinsic answer accuracy/F1 and intrinsic Recall/F1 of bridging objects.

Limitations

  • Stated: experiments cover only arithmetic reasoning and multi-hop QA; symbolic tasks are hard to ablate because their rationales are highly template-based with little variation.
  • Stated: invalid reasoning rationales were manually written, and a more systematic treatment of invalid reasoning is left for future work.
  • Stated: intrinsic evaluation relies on correctness of bridging objects and ground-truth annotations, which may not generalize and are costly to obtain; evident from the checklist: all results are reported with a single run due to limited budgets.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
