The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The reading

Large language models generate argumentative texts in which rhetorical devices appear at levels not matched by the certainty or knowledge they convey. The authors introduce a triadic epistemic-rhetorical marker taxonomy and three composite metrics to quantify the resulting mismatch. When the framework is applied to 225 texts from expert humans, non-expert humans, and LLMs, it detects elevated form-meaning divergence and more uniform device placement in the model outputs. Specific patterns include nearly twice the expert rate of tricolon and twice the human density of performed hesitancy markers. The metrics are designed to be automatable and therefore usable as a screening layer for epistemic miscalibration in generated content.

What carries the argument

Triadic epistemic-rhetorical marker (ERM) taxonomy operationalized through form-meaning divergence (FMD), genuine-to-performed epistemic ratio (GPR), and rhetorical device distribution entropy (RDDE) metrics.

What would settle it

An independent corpus of argumentative texts in which form-meaning divergence scores show no significant elevation for LLM outputs relative to human outputs would falsify the claim of systematic miscalibration.

Watch

Extended reading notes

Core claim

LLM-generated texts produce tricolon at nearly twice the expert rate while human authors produce erotema at more than twice the LLM rate. Performed hesitancy markers appear at twice the human density in LLM output. Form-meaning divergence is significantly elevated in LLM texts relative to both human groups, and rhetorical devices are distributed significantly more uniformly across LLM documents.

Load-bearing premise

The triadic ERM taxonomy and its operationalization via FMD, GPR, and RDDE metrics accurately isolate epistemic-rhetorical miscalibration without bias from corpus construction, annotation rules, or LLM generation artifacts.

3 major / 2 minor

Summary. The paper claims that LLMs exhibit systematic epistemic-rhetorical miscalibration, with rhetorical intensity disproportionate to epistemic grounding. It introduces a triadic ERM taxonomy operationalized via composite metrics FMD, GPR, and RDDE. Applied to 225 argumentative texts (~0.6M tokens) across human expert, human non-expert, and LLM sub-corpora, the framework reports LLM texts using tricolon at nearly twice the expert rate (Δ=0.95), humans using erotema more than twice the LLM rate, performed hesitancy markers at twice human density in LLMs, significantly elevated FMD in LLMs (p<0.001, Δ=0.68), and more uniform rhetorical device distribution in LLM documents. Findings align with Gricean pragmatics, Relevance Theory, and Brandomian inferentialism, with the pipeline presented as automatable for AI content screening.

Significance. If the metrics validly isolate epistemic-rhetorical decoupling independent of stylistic artifacts, the work offers a novel, automatable framework grounded in linguistic theory for detecting miscalibration in LLM outputs. This could strengthen AI-generated text detection pipelines and provide empirical tests of pragmatic theories in computational settings. The model-agnostic results, large corpus size, and reported effect sizes add potential impact for NLP applications in content moderation and evaluation.

major comments (3)
  1. [Methods] Methods section: The operational definitions, formulas, and validation procedures for FMD, GPR, and RDDE are not provided. Without explicit computation details (e.g., how form-meaning divergence is scored from annotations or how the genuine-to-performed ratio is derived), it is impossible to confirm that the metrics measure epistemic-rhetorical miscalibration rather than LLM stylistic regularities such as repetition or formality patterns. This directly affects interpretation of the central results including FMD Δ=0.68 (p<0.001).
  2. [Corpus and Annotation] Corpus construction and annotation: No details are given on sampling criteria for the 225 texts, inter-annotator agreement for the ERM taxonomy, or controls for confounders like text length, topic, or LLM prompt design. These omissions leave open the possibility that differences in device rates (e.g., tricolon Δ=0.95) and RDDE uniformity arise from corpus or annotation biases rather than the hypothesized decoupling.
  3. [Results] Results section: While p-values and effect sizes are reported, the manuscript does not specify the exact statistical tests, sample sizes per comparison, or corrections for multiple testing. This weakens assessment of claims such as significantly more uniform rhetorical device distribution across LLM documents.
minor comments (2)
  1. [Abstract] Abstract: The token count is stated as 'approximately 0.6 Million tokens'; reporting the exact total would aid reproducibility.
  2. [Discussion] Discussion: Adding an explicit limitations paragraph addressing potential LLM generation artifacts (e.g., prompt-induced patterns) would strengthen the manuscript.

This directly affects interpretation of the central results including FMD Δ=0.68 (p<0.001).

    Authors: We agree that the current Methods section lacks sufficient explicit detail on the metrics. In the revised manuscript, we will expand this section to include the full operational definitions of the ERM taxonomy, the precise mathematical formulas for computing FMD (form-meaning divergence), GPR (genuine-to-performed epistemic ratio), and RDDE (rhetorical device distribution entropy), along with step-by-step validation procedures, annotation guidelines, and pseudocode for the automatable pipeline. These additions will demonstrate how the metrics isolate epistemic-rhetorical decoupling from purely stylistic factors such as repetition or formality. revision: yes

  2. Referee: [Corpus and Annotation] Corpus construction and annotation: No details are given on sampling criteria for the 225 texts, inter-annotator agreement for the ERM taxonomy, or controls for confounders like text length, topic, or LLM prompt design. These omissions leave open the possibility that differences in device rates (e.g., tricolon Δ=0.95) and RDDE uniformity arise from corpus or annotation biases rather than the hypothesized decoupling.

    Authors: We acknowledge the importance of transparency in corpus construction. The revised manuscript will include a dedicated subsection detailing the sampling criteria for selecting the 225 argumentative texts (~0.6M tokens), report inter-annotator agreement statistics (e.g., Cohen's kappa or Fleiss' kappa) for the ERM taxonomy annotations, and describe the controls applied for potential confounders including text length normalization, topic balancing across sub-corpora, and standardization of LLM prompt designs. These additions will help rule out alternative explanations for the observed differences. revision: yes

  3. Referee: [Results] Results section: While p-values and effect sizes are reported, the manuscript does not specify the exact statistical tests, sample sizes per comparison, or corrections for multiple testing. This weakens assessment of claims such as significantly more uniform rhetorical device distribution across LLM documents.

    Authors: We agree that full statistical reporting is necessary for rigorous evaluation. In the revised Results section, we will explicitly specify the statistical tests used for each comparison (e.g., independent t-tests or Mann-Whitney U tests for FMD and device rates), the exact sample sizes per group (225 texts divided across the three sub-corpora), and the multiple-testing correction applied (e.g., Bonferroni or FDR). This will allow readers to fully assess the robustness of findings such as the elevated FMD (p<0.001, Δ=0.68) and RDDE uniformity. revision: yes

full rationale

The paper proposes a novel triadic ERM taxonomy and operationalizes it via author-defined composite metrics (FMD, GPR, RDDE) explicitly motivated by external linguistic theories (Gricean pragmatics, Relevance Theory, Brandomian inferentialism). These are then applied empirically to a 0.6M-token corpus spanning human expert, human non-expert, and LLM texts, producing statistical comparisons (e.g., tricolon rate Δ=0.95, FMD p<0.001 Δ=0.68). No equations, definitions, or self-citations are present that reduce any reported result to a fitted parameter, self-referential definition, or prior author work by construction. The derivation chain is an independent empirical measurement using a new framework and remains self-contained against external benchmarks.

abstract

Large language models (LLMs) exhibit systematic miscalibration with rhetorical intensity not proportionate to epistemic grounding. This study tests this hypothesis and proposes a framework for quantifying this decoupling by designing a triadic epistemic-rhetorical marker (ERM) taxonomy. The taxonomy is operationalized through composite metrics of form-meaning divergence (FMD), genuine-to-performed epistemic ratio (GPR), and rhetorical device distribution entropy (RDDE). Applied to 225 argumentative texts spanning approximately 0.6 Million tokens across human expert, human non-expert, and LLM-generated sub-corpora, the framework identifies a consistent, model-agnostic LLM epistemic signature. LLM-generated texts produce tricolon at nearly twice the expert rate ($\Delta = 0.95$), while human authors produce erotema at more than twice the LLM rate. Performed hesitancy markers appear at twice the human density in LLM output. FMD is significantly elevated in LLM texts relative to both human groups ($p < 0.001, \Delta = 0.68$), and rhetorical devices are distributed significantly more uniformly across LLM documents. The findings are consistent with theoretical intuitions derived from Gricean pragmatics, Relevance Theory, and Brandomian inferentialism. The annotation pipeline is fully automatable, making it deployable as a lightweight screening tool for epistemic miscalibration in AI-generated content and as a theoretically motivated feature set for LLM-generated text detection pipelines.
