· Lean TheoremArgument Reconstruction as Supervision for Critical Thinking in LLMs

The pith
Training LLMs to reconstruct arguments improves their performance on critical thinking tasks.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Models trained to reconstruct arguments with the GAAR engine and the resulting Arguinas dataset outperform models that receive no such training across seven critical thinking tasks, with the largest gains coming from the new dataset.
What carries the argument
The GAAR engine, an automatic system that reconstructs arbitrary arguments by surfacing their underlying inferences.
If this is right
- Argument reconstruction can serve as a single training signal that transfers to multiple downstream reasoning tasks.
- Synthetic datasets built automatically from existing arguments can provide high-quality supervision for reasoning skills.
- Explicit reconstruction training may reduce reliance on surface patterns in favor of deeper inference steps.
- The same engine that creates training data can also be used to inspect or debug model outputs on new arguments.
Where Pith is reading between the lines
- If reconstruction training works, future models might be improved by inserting reconstruction steps into their inference pipelines rather than only at training time.
- The approach suggests that many reasoning failures in LLMs stem from unstated inferences that become visible once reconstruction is required.
- Similar reconstruction-based supervision could be tested on tasks outside the seven studied here, such as legal or scientific argument evaluation.
Load-bearing premise
The arguments reconstructed by the GAAR engine accurately capture the original inferences without introducing systematic errors or biases.
What would settle it
A new set of critical thinking tasks on which models trained with GAAR reconstructions show no improvement or perform worse than models trained without them would falsify the claim.

To think critically about arguments, human learners are trained to identify, reconstruct, and evaluate arguments. Argument reconstruction is especially important because it makes an argument's underlying inferences explicit. However, it remains unclear whether LLMs can similarly enhance their critical thinking ability by learning to reconstruct arguments. To address this question, we introduce a holistic framework with three contributions. We (1) propose an engine that automatically reconstructs arbitrary arguments (GAAR), (2) synthesize a new high-quality argument reconstruction dataset (Arguinas) using the GAAR engine, and (3) investigate whether learning argument reconstruction benefits downstream critical thinking tasks. Our experimental results show that, across seven critical thinking tasks, models trained to learn argument reconstruction outperform models that do not, with the largest performance gains observed when training on the proposed Arguinas dataset.

Referee Report
Summary. The paper introduces GAAR, an automatic engine for reconstructing arbitrary arguments, uses it to synthesize the Arguinas dataset, and reports that LLMs trained to perform argument reconstruction outperform models without such training across seven critical thinking tasks, with the largest gains when using Arguinas.
Significance. If the reconstructions prove faithful and the experiments are properly controlled, the work could establish argument reconstruction as a useful supervision signal for improving LLMs' critical thinking. The new engine and dataset would then constitute concrete resources for the community.
major comments (2)
- [Abstract] Abstract: the central claim of outperformance on seven tasks with largest gains on Arguinas is stated without any description of experimental setup, baselines, statistical tests, or controls for dataset quality, leaving the result with limited verifiable support.
- [Dataset creation] Dataset creation section: no fidelity metrics, inter-annotator agreement scores, or comparison against expert gold reconstructions are supplied for the GAAR-generated Arguinas data; without these, it is impossible to rule out that downstream gains arise from dataset artifacts rather than genuine inference learning.
minor comments (2)
- Clarify the precise architecture and prompting strategy of the GAAR engine, including any hyperparameters or few-shot examples used.
- List the seven critical thinking tasks explicitly and indicate which metrics are used for each.

Referee: [Abstract] Abstract: the central claim of outperformance on seven tasks with largest gains on Arguinas is stated without any description of experimental setup, baselines, statistical tests, or controls for dataset quality, leaving the result with limited verifiable support.
Authors: We agree that the abstract is overly concise and does not sufficiently detail the experimental setup to support the claims. In the revised manuscript, we will expand the abstract to briefly describe the seven critical thinking tasks, the baselines (models trained without argument reconstruction), the use of statistical tests for significance, and reference the dataset quality controls discussed in the main text. revision: yes

Referee: [Dataset creation] Dataset creation section: no fidelity metrics, inter-annotator agreement scores, or comparison against expert gold reconstructions are supplied for the GAAR-generated Arguinas data; without these, it is impossible to rule out that downstream gains arise from dataset artifacts rather than genuine inference learning.
Authors: This is a valid observation. The current manuscript does not report these metrics, which limits the ability to fully rule out artifacts. We will revise the Dataset creation section to include fidelity metrics for GAAR (e.g., accuracy on held-out expert-annotated arguments), inter-annotator agreement scores from a human evaluation of a sample of Arguinas, and direct comparisons to expert gold reconstructions. These additions will provide stronger evidence that performance gains reflect genuine inference learning. revision: yes
Circularity Check
No significant circularity; empirical results rest on independent evaluation
full rationale
The paper introduces GAAR and Arguinas then measures downstream gains via standard supervised fine-tuning and task-specific benchmarks across seven held-out critical thinking tasks. No equations, fitted parameters, or self-citations are invoked to derive the performance improvements by construction; the central claim is an empirical observation that remains falsifiable by external replication or human validation of the reconstructions. The derivation chain is therefore self-contained and does not reduce to its inputs.
