They want to pretend not to understand: The Limits of Current LLMs in Interpreting Implicit Content of Political Discourse

Pith's one-line read Current LLMs mostly fail to decode implicit meanings in political speech, the paper argues.

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 load-bearing object is IMPAQTS-PID, a new dataset built from the IMPAQTS corpus: 31,822 passages from Italian parliamentary and rally speeches, each containing an expert-annotated implicature or presupposition together with a fixed-format comment ('it implies that...' or 'it presupposes that...') and the four preceding sentences needed to interpret it. Around this dataset the paper builds two probes: a multiple-choice generation task with topic-matched distractors, and an open-ended generation task whose outputs are judged by expert linguists on a five-point scale. The chain-of-thought prompt, adapted from the corpus annotation instructions, is the mechanism that most improves open-ended performance, raising fully correct answers from 21% to 27% and lowering totally wrong answers from 39% to 33%.
What would settle it
Have independent expert linguists explain the same passages without seeing the IMPAQTS comments, then measure how often two human explanations match each other at the same 'totally correct' standard used for the models. If human-human exact-match rates are close to the model's 27% or if annotators frequently disagree about which nuance is intended, the reported failure rates would reflect task ambiguity rather than a specific LLM deficit; if human-human agreement is high while model-human agreement stays at a quarter, the conclusion stands.
Extended reading notes
Core claim
On the paper's own terms, the discovery is a negative result with a precise magnitude: tested LLMs (GPT-4o-mini, Aya Expanse 8B, LLAMA3.1 8B, LLAMA3.2 3B) all perform above chance but far below expert level on interpreting Italian political implicatures and presuppositions. In the multiple-choice setup, all models except GPT-4o-mini fall below a simple n-gram similarity baseline, and GPT-4o-mini itself lands at 70% accuracy, more than 20 points below the bootstrap-estimated ceiling of 91%. In the open-ended setup, where the model must generate an explanation of the implied meaning, expert linguist judges rate the best model's answer as totally correct in only about one in four cases, with roughly a third totally wrong; the chain-of-thought prompt reduces but does not eliminate the failures. The paper takes this as evidence that current LLMs lack the pragmatic capacity to handle naturalistic, context-dependent political language, and identifies speaker identity, historical setting, and political affiliation as missing information that future work should supply.
Load-bearing premise
The whole evaluation assumes that each passage of implicit political content has exactly one correct explanation, the comment written by the IMPAQTS annotators, so that any model output expressing a different but plausible reading is counted as totally wrong.
Editorial extensions
If this is right
- If the result generalizes, LLM-based tools that monitor political discourse cannot yet be trusted to detect or explain manipulative implicatures and presuppositions on their own.
- Multiple-choice performance is inflated relative to open-ended generation, so evaluations that rely on selection tasks overestimate pragmatic understanding.
- Chain-of-thought prompting is a cheap, effective lever for pragmatic tasks and worth combining with other interventions; few-shot examples did not help.
- The release of IMPAQTS-PID gives the field a shared testbed for measuring progress on this task, as the paper itself releases its data and code.
Reading between the lines
- Because the evaluation treats the single IMPAQTS annotation as the only correct reading, the reported 'totally correct' rates are likely a lower bound on genuine pragmatic competence; political implicatures often support several plausible interpretations, as the appendix's worked example itself shows.
- A natural test of this bound is to measure human-human agreement on the same explanation task; if experts disagree at a rate close to the model's 'totally wrong' rate, part of the measured failure is the task's own ambiguity, not a model deficit.
- The strong gap between structured pragmatic benchmark tasks and naturalistic political passages suggests that benchmark scores may not transfer to ecological discourse; a multi-genre pragmatic benchmark that includes political speech would test this directly.
- Enriching prompts with speaker, party, and historical context could improve explanation quality but would also let models reproduce partisan biases from pretraining; any such intervention should be evaluated for both accuracy and fairness.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper introduces IMPAQTS-PID, a dataset of 31,822 Italian political discourse passages annotated for implicatures and presuppositions, derived from the IMPAQTS corpus. Using this resource, the authors evaluate four LLMs (GPT4o-mini, Aya Expanse 8B, Llama 3.1 8B, Llama 3.2 3B) on two tasks: a multiple-choice generation (MCG) task over four explanation candidates, and an open-ended generation (OEG) task evaluated by expert linguists. The central empirical claim is that all tested models struggle to interpret implicit content: the best MCG accuracy is 70% against an estimated ceiling of 91%, and in OEG the best model produces fully correct explanations only 21% (zero-shot) to 27% (chain-of-thought) of the time. The paper also reports that chain-of-thought prompting improves OEG performance and releases the data and code.
Significance. The work is significant as a first large-scale NLP use of the IMPAQTS corpus, a substantial and ecologically valid resource of real political speeches with expert annotations of manipulative implicit content. The two-task design, the human validation of the amount of preceding context needed, the inclusion of an n-gram baseline, and the release of data and code are clear strengths. If the quantitative claims withstand scrutiny, the paper provides useful negative evidence about LLM pragmatic competence in a naturalistic, high-stakes domain. However, the central quantitative claims currently rest on evaluation choices that need tightening: the OEG gold standard assumes a single correct interpretation, the OEG results come from one model with a small sample and single annotators, and the MCG distractor generation is acknowledged as a confound. These issues are load-bearing for the headline conclusion and should be addressed before the findings can be considered robust.
major comments (4)
- [Section 4.3, Appendix C.2] The OEG evaluation treats the IMPAQTS annotation as the unique correct explanation of each implicit passage. The instructions in Appendix C.2 explicitly tell judges to assess 'whether the model has captured the nuance implied by the human annotator, not whether the generated output makes sense,' and the worked example marks a plausible model output as 'totally wrong' because it does not reproduce the specific annotation 'Italy is stalled.' For political implicatures and presuppositions, which are cancellable, context-dependent, and often admit multiple legitimate readings, this uniqueness assumption is not supported. The paper's own context-sufficiency study reports only fair-to-moderate inter-annotator agreement (Fleiss kappas 0.23–0.41, Appendix C.1), and Section 7 concedes that the open-ended evaluation 'may not fully capture the complexity of models outputs.' Since Section 5.1 acknowledges that the MCG task is confounded by distractor selection, the OEG result is the main unconfounded evidence for the central negative claim, and the 21–27% 'totally correct' figures would be overstated if some 'totally wrong' outputs are acceptable alternative readings. The authors should either provide evidence that the IMPAQTS annotations are the unique valid readings, or add an evaluation category for plausible-but-different interpretations and report how often model outputs fall into that category.
- [Section 5.2, Figure 4] The OEG experiment uses a single model (GPT4o-mini), 150 samples per prompting condition, and a single expert annotator per output, with no inter-rater agreement and no significance testing. The claimed CoT improvement—'totally correct' rising from 21% to 27% and 'totally wrong' falling from 39% to 33%—may be within sampling variability; a simple two-proportion test on these sample sizes would not be significant. This weakens both the 'CoT boosts performance' claim and the use of OEG as the unconfounded confirmation that current LLMs generally fail at this task. The authors should report confidence intervals, use multiple annotators or adjudication for at least a subset, and apply an appropriate statistical test for the prompting-condition comparisons.
- [Section 5.1, Figures 1–3] The MCG results are conditional on the topic-model-based distractor generation method, and the authors themselves state that 'distractor selection can significantly impact model performance, introducing confounding factors and limiting result robustness.' Only GPT4o-mini consistently beats the BLEU-4 baseline, and the reported accuracy gap between hard and easy negatives shows that the task is highly sensitive to the distractor pool. As presented, the 70% accuracy figure is therefore an estimate for one particular distractor distribution, not a general measurement of the models' ability to identify correct explanations of implicit content. The paper would be stronger if it validated distractor plausibility through human pretesting and reported human accuracy on the same MCG items, so that the ceiling comparison is a direct human–model comparison rather than an extrapolation from the context-sufficiency study.
- [Section 4.3] The chain-of-thought prompt is 'adapted from the detailed instructions given to the IMPAQTS corpus annotators,' and the ground-truth labels were produced under the same annotation framework, which includes one of this paper's co-authors as a corpus co-creator. This creates a risk of circularity: the CoT condition essentially primes the model with the label-generation scheme, so the observed CoT gain may reflect alignment with the annotation instructions rather than improved pragmatic reasoning in general. An ablation with a neutral or theory-agnostic reasoning prompt, or with a prompt constructed from a different pragmatic framework, would help establish that the benefit is not an artifact of prompt–label overlap.
minor comments (6)
- [Abstract and Conclusion] The phrase 'all tested models struggle' is supported by the MCG experiment for all four models, but the OEG experiment was run only with GPT4o-mini; the abstract and conclusion should be phrased to make this asymmetry explicit.
- [Section 3.3] Section 3.3 says the dataset retrieves 'the preceding 4 sentences,' while Section 3.2 describes allowing annotators to see up to five left-hand sentences; please clarify whether four sentences means four context sentences plus the target sentence or four context sentences total.
- [Section 5.1] The estimated ceiling of 91% is described as an 88% bootstrapped value plus an additional 3% 'standing for a random chance level accuracy in the remaining samples'; the derivation of this additive correction and the bootstrap details should be reported.
- [Appendix D] The refusal rates for Llama 3.1 8B and Llama 3.2 3B are reported as 0.0015% and 0.003%, but 45 and 91 refusals out of 31,822 samples correspond to about 0.14% and 0.29%, respectively; these percentages appear to be off by two orders of magnitude.
- [Section 5.2, Table 1] The statement that 'small and consistent differences' between implicatures and presuppositions are 'notably similar' is based on proportions without any uncertainty quantification; adding confidence intervals or a test would make the comparison more rigorous.
- [Appendix G.1] In the description of the LLM-as-judge results, the text says 'partially correct answers decrease from 0.1% of both Zero-shot and Few-shot to 0.06% of CoT,' but Figure 6 appears to show 10% and 6%; the decimal notation should be corrected for consistency.
Circularity Check
No significant circularity: the central result is an empirical benchmark against a published expert-annotated corpus; no prediction reduces to its inputs by construction.
full rationale
The paper's central claim—that LLMs struggle to interpret presuppositions and implicatures in Italian political discourse—is an empirical evaluation, not a derivation. The gold labels are the expert annotations of the separately published IMPAQTS corpus (Cominetti et al., 2024), and the MCG and OEG tasks measure model outputs against those published labels. Although one co-author (Panunzi) is also a co-author of the corpus paper, the annotations are external data, not a theorem or fitted parameter of the present paper; the self-citation is not load-bearing. The CoT prompt is adapted from the IMPAQTS annotation instructions, which creates a possible alignment between the prompt and the gold standard, but this affects only the interpretation of the CoT improvement; the zero-shot and few-shot conditions, which do not receive the annotation manual, show the same overall negative result. The strict 'totally wrong' criterion in Appendix C.2 (judge whether the model 'captured the nuance implied by the human annotator, not whether the generated output makes sense') is a validity concern about whether political implicatures admit only one correct reading—and the authors acknowledge the evaluation 'may not fully capture the complexity of models outputs'—but this is not circularity: matching an expert annotation is a legitimate, if conservative, operationalization of correctness. No equation or prediction is equivalent to its input by construction, and no uniqueness claim is imported from the authors' prior work.

Implicit content plays a crucial role in political discourse, where speakers systematically employ pragmatic strategies such as implicatures and presuppositions to influence their audiences. Large Language Models (LLMs) have demonstrated strong performance in tasks requiring complex semantic and pragmatic understanding, highlighting their potential for detecting and explaining the meaning of implicit content. However, their ability to do this within political discourse remains largely underexplored. Leveraging, for the first time, the large IMPAQTS corpus, which comprises Italian political speeches with the annotation of manipulative implicit content, we propose methods to test the effectiveness of LLMs in this challenging problem. Through a multiple-choice task and an open-ended generation task, we demonstrate that all tested models struggle to interpret presuppositions and implicatures. We conclude that current LLMs lack the key pragmatic capabilities necessary for accurately interpreting highly implicit language, such as that found in political discourse. At the same time, we highlight promising trends and future directions for enhancing model performance. We release our data and code at https://github.com/WalterPaci/IMPAQTS-PID
