The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The central object is the Rosetta Stone problem format, a puzzle with a meta section naming the foreign language, a train set of translation pairs, and a test set with one side missing, so that solving requires inducing a small grammar and dictionary. The argument is carried by a controlled comparison of three prompting conditions: IO, which supplies the task and answer format only; CoT, which adds step-by-step reasoning directives inside a two-phase extract-rules-then-apply strategy; and SPP, which simulates discussion among expert personas under a facilitator. The paper evaluates all conditions with exact match, BLEU-2, chrF, characTER, and cosine similarity of Sentence-BERT embeddings, and it classifies reasoning failures into dictionary contradictions and rule contradictions to explain why explicit reasoning underperforms.
What would settle it
Re-run all three prompting conditions on the same 86 Puzzling Machine problems and 28 LO problems with nonzero sampling temperature across, say, ten seeds, and compare confidence intervals on EM and the translation metrics; if the IO-over-CoT intervals overlap broadly, the paper's central ordering is not established. Alternatively, a single held-out set of comparable Rosetta Stone puzzles on which CoT matches or exceeds IO would falsify the claimed universality of the effect.
Extended reading notes
Core claim
The central claim is that the simplest prompt wins. Across the 86-problem Puzzling Machine set and the 28-problem Linguistics Olympiad set, IO prompting outperformed both CoT and SPP on every reported metric: exact match, BLEU-2, chrF, characTER, and cosine similarity of sentence embeddings. The paper attributes the gap to the quality of the reasoning traces themselves: CoT repeatedly commits to unsupported rules and dictionary pairings without retrospective correction, SPP expert personas rarely challenge one another, and GPT-4's own stated rules or dictionaries are sometimes contradicted by its answers. The paper's explanation is that an incomplete or wrong intermediate grammar becomes noise that hurts translation, whereas IO answers directly from the example pairs.
Load-bearing premise
The load-bearing premise of the comparison is that one run of each prompting method adequately represents that method's performance; the paper reports no sampling variance, temperature, or significance test, so the small observed margins could change or reverse on another run.
Editorial extensions
If this is right
- For Rosetta Stone-style translation puzzles, IO is the empirically stronger baseline, and explicit-reasoning prompts need to justify their cost.
- CoT's inferred rules and dictionaries should not be treated as reliable; without retrospective correction they can propagate initial errors.
- SPP's expert dialogue added little critical disagreement in this domain, so the value of multi-persona prompting is not automatic.
- The dictionary-vs-rule contradiction taxonomy provides a concrete diagnostic for checking whether a model's stated reasoning matches its output.
- If the paper's noise explanation is right, then methods that use the reasoning trace only to verify or revise an answer, rather than to produce it, may combine the best of both approaches.
Reading between the lines
- Because each condition appears to have been run once, with no reported temperature, seed, or variance, the small IO-over-CoT margins (e.g., EM 0.217 vs 0.183 on the LO set) could reverse under sampling; re-running with multiple seeds is a direct, testable check.
- A natural extension the paper does not pursue is to compare IO against CoT with self-consistency or a verification stage, which would test whether the problem is reasoning itself or the lack of correction.
- The contradiction taxonomy could be automated and applied to other LLM reasoning tasks as a faithfulness measure, independently of whether the final answer is correct.
- The observed language-familiarity tiers suggest that prompting effects may differ by whether GPT-4 had substantial exposure to the target language; a stratified analysis by tier would sharpen the comparison.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper compares four prompting strategies (Input-Output, Chain-of-Thought, Solo Performance Prompting, and a Zero-Example variant) applied to GPT-4 on two collections of Rosetta Stone linguistic puzzles: 86 problems from the Puzzling Machine competition and 28 problems obtained or adapted from UKLO/NACLO. It evaluates outputs with EM, BLEU, chrF, CharacTER, and cosine similarity, and reports that plain IO is the best prompting method on essentially all metrics while CoT and SPP produce explicit reasoning paths that are frequently incomplete or self-contradictory. The paper also proposes a three-tier categorization of GPT-4's language proficiency based on ZeroEx CharacTER scores and discusses qualitative examples of rule and dictionary contradictions.
Significance. If the main finding held, it would be a meaningful empirical counterpoint to the common assumption that eliciting explicit reasoning paths improves LLM performance on constrained translation and reasoning tasks. The evaluation uses external benchmarks and standard metrics, the dataset construction is mostly transparent, and the qualitative analysis of CoT/SPP failure modes is a genuine strength; there is no fitted parameter or circular derivation that would make the result an artifact of the authors' assumptions. However, the impact is currently limited by the small LO dataset, the absence of repeated runs or significance tests, and a serious metric-direction error involving CharacTER, which invalidates the claim that IO wins on 'every' reported metric.
major comments (4)
- [§4, §5.1, Tables 2–3] Section 4 defines CharacTER by citing Wang et al. (2016), i.e., a character-level translation edit rate for which lower values are better, but Section 5.1 and Tables 2–3 consistently treat larger values as better. In Table 2, ZeroEx's CharacTER of 0.317 is actually the best score, contrary to the sentence 'ZeroEx lags behind in all metrics'; IO's 0.642 is the worst on that metric, and CoT (0.618) and SPP (0.516) both beat IO. The same inversion appears in Table 3, and Table 1's FE_CTER and EF_CTER columns presumably suffer from the same issue if they are error rates. As a result, the central claim that IO outperforms CoT and SPP on every reported metric is false as stated, and the proficiency-tier analysis in Section 5.3, which builds on ZeroEx CharacTER values in Figure 4, needs to be re-derived under the correct direction of the metric.
- [§3.2, Tables 1–3] The comparative claim rests on a single set of outputs per condition, with no report of sampling temperature, number of runs, variance, confidence intervals, or significance tests. The margins separating IO from CoT and SPP are small (e.g., EM 33.79 vs 31.37 in Table 1 and 0.217 vs 0.183 in Table 2), so under GPT-4's stochastic decoding the observed ranking could plausibly reverse on a second run. The authors should either add repeated runs with error bars or significance tests, or explicitly reframe the findings as single-run exploratory observations without claiming stable superiority.
- [§3.1, §3.2] The adapted LO dataset is not released, the adaptation procedure is not specified in enough detail to reproduce, and the exact prompt templates for IO, ZeroEx, CoT, and SPP are not provided. Without the adapted problems, the full prompt texts, and a clear statement of which conditions used the two-phase reasoning strategy, the evaluation cannot be independently checked or re-run by other researchers.
- [§5.3] The assignment of languages to Limited, Moderate, and High Proficiency tiers in Section 5.3 is presented without any stated threshold or statistical criterion, and Figure 4 is described only as a plot of ZeroEx CharacTER scores without specifying axis labels or a legend. Please state the quantitative rule used to separate the tiers and confirm whether the tier assignments survive after correcting the CharacTER direction issue.
minor comments (6)
- [§5.1] In Section 5.1, 'Information Ordering (IO)' and 'Self-Paced Learning (SPP)' are incorrect expansions; these should be Input-Output Prompting and Solo Performance Prompting.
- [Tables 1–3] The metric name is written inconsistently as 'CharacTER', 'characTER', and 'ChF-3'; please use 'characTER' and 'chrF' consistently throughout.
- [References] The entries Wei et al. 2023a and 2023b appear to be the same paper, and Wu et al. 2023a and 2023b likewise duplicate; please distinguish or merge them.
- [Conclusion] The phrase 'our results(see figure)' in the conclusion does not name a figure; it should refer to Figure 4 or be removed.
- [Abstract] The abstract contains formatting errors such as 'explorespecificpromptingtechniques' and 'LLMs’ability'; please proofread the text.
- [§3.2] The description of ZeroEx says it 'excludes example pairs,' but it is unclear whether ZeroEx still receives the Meta section and test prompt; including one full example of each prompt type would remove this ambiguity.
Circularity Check
No significant circularity: the paper's claims are empirical benchmark comparisons, not derivations from fitted inputs or self-citation chains.
full rationale
This paper reports an empirical evaluation of three prompting methods (IO, CoT, SPP) plus a ZeroEx variant on two external benchmark datasets (Puzzling Machine Competition and Linguistics Olympiad problems). The central claim, that IO outperforms CoT and SPP on the reported metrics, is an observed result, not a quantity derived from definitions or from fitted parameters. The evaluation metrics (EM, BLEU, chrF, characTER, CosSim) are standard external measures with stated references, and the benchmark data are external; no metric score is defined in terms of the paper's own conclusions. The only self-citation in the reference list, Lin et al. (2023), is not cited in the body and is not used to justify any load-bearing assumption, uniqueness claim, or ansatz. The paper's reasoning-quality discussion is qualitative and does not feed back into the scores. One notable internal issue is that characTER is an error rate (lower is better) while the text ranks higher values as better, and this affects the accuracy of some narrative claims; however, this is a correctness or interpretation problem, not a circularity problem, because the scores themselves were computed independently and are not constructed to force IO's superiority. There is no equation, fitted parameter, or self-citation chain that makes the observed outcome equivalent to the paper's inputs, so the circularity score is 0.
Assumptions & free parameters
assumptions (3)
- domain assumption The automatic metrics (BLEU-2, characTER, chrF, CosSim) are valid proxies for translation quality on Rosetta Stone problems.
- domain assumption The adapted LO problems preserve the difficulty and linguistic validity of the original competition puzzles.
- domain assumption Single-run generation is representative of each prompting method's performance.

This paper investigates the utilization of Large Language Models (LLMs) for solving complex linguistic puzzles, a domain requiring advanced reasoning and adept translation capabilities akin to human cognitive processes. We explore specific prompting techniques designed to enhance ability of LLMs to reason and elucidate their decision-making pathways, with a focus on Input-Output Prompting (IO), Chain-of-Thought Prompting (CoT), and Solo Performance Prompting (SPP). Utilizing datasets from the Puzzling Machine Competition and various Linguistics Olympiads, we employ a comprehensive set of metrics to assess the performance of GPT-4 0603, a prominent LLM, across these prompting methods. Our findings illuminate the potential of LLMs in linguistic reasoning and complex translation tasks, highlighting their capabilities and identifying limitations in the context of linguistic puzzles. This research contributes significantly to the broader field of Natural Language Processing (NLP) by providing insights into the optimization of LLM applications for improved reasoning and translation accuracy, thereby enriching the ongoing dialogue in NLP advancements.
