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 I-ScienceQA benchmark, containing 8,100 samples built from ScienceQA test sets and divided into four distraction scenarios: Add Image, Insert Image, Add Hint, and Insert Hint. Visual distractions are generated with Stable Diffusion and images from Unsplash and PromeAI, while textual distractions are produced with GPT-3.5-turbo. Evaluation relies on exact-match accuracy and exact-match degradation, defined as the difference in accuracy between the original and distracted sets. This machinery isolates the impact of each distraction modality on model reasoning.
What would settle it
Human annotators could verify all 8,100 distracted samples to confirm that the correct answer is unchanged; if even a small fraction of distractors alter the correct answer, the reported degradation values would need to be recomputed and would not cleanly reflect distraction robustness.
Extended reading notes
Core claim
The central discovery is that most state-of-the-art VLMs, including GPT-4o, show measurable exact-match degradation on science questions when irrelevant content is added to the image or the text. The largest drops occur in the 'Add Hints' scenario, where unrelated text replaces a missing hint: Qwen2-VL-2B falls by 6.35 points and InternVL2-2B by 9.05 points. Textual distractions are consistently more harmful than visual ones, and model scale helps but does not guarantee robustness, with InternVL2-8B showing the smallest degradation in most scenarios. The paper reports these findings through a new benchmark and a degradation metric that quantifies the effect of each distraction type.
Load-bearing premise
The entire degradation measure rests on the assumption that the added images and texts are irrelevant to the question and never change the correct answer, so any accuracy drop must stem from distraction rather than from a changed ground truth.
Editorial extensions
If this is right
- VLM benchmarks should include distraction robustness as a standard evaluation axis, since clean benchmarks overstate real-world capability.
- Textual distractions are a particular weak point, so future training should focus on ignoring irrelevant text more aggressively.
- Model scaling reduces but does not eliminate distraction vulnerability; architecture and training data matter as much as size.
- Simple defenses such as instruction prompts and robust vision encoders recover only part of the lost accuracy, leaving room for stronger mitigation strategies.
- The exact-match degradation metric can be reused as a standard measure for distraction robustness in future evaluations.
Reading between the lines
- Because the benchmark only uses science questions, degradation may be even larger in tasks demanding tighter visual-text alignment, such as medical or technical image interpretation.
- The paper's assumption that distractors are answer-neutral is not verifiable in the submitted text; if some distractors alter the correct answer, the reported degradation would overstate true vulnerability.
- A testable extension is to fine-tune models on distraction-augmented samples and measure whether the lost accuracy is recovered, since the same models score high on clean data.
- The 'Add Hints' scenario being the most harmful suggests these models over-weight textual priors; probing attention weights could test whether the models fixate on inserted text.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper presents I-ScienceQA, a robustness benchmark derived from the ScienceQA dataset, in which visual and textual distractions are injected into test samples across four scenarios (Add Image, Insert Image, Add Hint, Insert Hint). Fourteen vision-language models ranging from 1B to 34B parameters, plus GPT-4o, are evaluated with an Exact Match degradation metric. The main findings are that most VLMs degrade under distractions, textual distractions are more harmful than visual ones, InternVL2 (8B) shows the least degradation, larger models tend to be more robust, and prompt-engineering or robust-CLIP defenses provide only partial relief. The authors explicitly disclose in Section 6.2 that InternVL2 and LLaVA were trained on ScienceQA, but they nonetheless draw model-level robustness conclusions from the same benchmark.
Significance. If the experimental claims could be fully verified, I-ScienceQA would be a useful and reasonably large robustness benchmark with an easy-to-reproduce evaluation protocol, covering well-known open models and a proprietary model (GPT-4o), a clear performance metric, and a natural visual-versus-textual distraction taxonomy. Credit is due for including GPT-4o alongside open models, for openly discussing training-data contamination in Section 6.2, and for quantifying the limited effect of two defenses. However, two issues are currently load-bearing for the paper's claims: the benchmark is built on ScienceQA, which Section 6.2 admits was part of the training data for InternVL2 and LLaVA, so the headline robustness ranking may reflect memorization rather than distraction handling; and the validity of every degradation number depends on the assumption that no generated distraction changes the correct answer, an assumption whose validation is deferred to an appendix that is not present in the submitted text. The contribution is therefore significant only conditionally, pending a deconfounding analysis and release of the validation material.
major comments (3)
- [§6.2, Table 1] The paper's headline conclusion that "models such as InternVL2 demonstrate a higher degree of robustness" is drawn from Table 1, which is evaluated on a benchmark derived from ScienceQA, and Section 6.2 states that InternVL2 and LLaVA were trained on ScienceQA. The authors acknowledge that "their performance metrics might be artificially inflated" but do not act on this disclosure: the model-level ranking is still presented without decontamination. Because the central claim is that InternVL2 is robust, the comparison is currently confounded. The authors should either restrict the robustness ranking to models not trained on ScienceQA or provide additional evidence that contamination does not drive the InternVL2 advantage, for example by measuring degradation on a subset of I-ScienceQA built from non-ScienceQA sources or by comparing against a held-out ScienceQA split that was unseen by the trained models.
- [§3.1, §3.2, Figure 1] Every degradation figure in Table 1 is computed by comparing the distracted sample against the original ScienceQA label, so the benchmark's validity rests on the assumption that each generated visual or textual distraction is irrelevant to the question and never changes the correct answer. The definitions of the visual distraction subtypes, the GPT-3.5-generated textual distraction types, dataset statistics, and sample images are repeatedly deferred to "the Appendix" (Sections 3.1, 3.2, 6.2, Figure 1), but no appendix is present in the submitted text. A reader therefore cannot inspect a single distracted example to confirm label preservation. The manuscript must include the appendix material as well as explicit validation of the label-preservation property, such as human or automated checks with a reported label-change rate, before the magnitudes of the reported degradations can be interpreted.
- [§3.2, Scenario III (Add Hint)] The Add Hint scenario replaces the original "N/A" hint with GPT-3.5-generated content, so the "Original" condition contains no hint at all while the "Distraction" condition introduces a new textual clue. Any new hint changes the semantics of the input, and the paper states that "contradictory information" is one of the generated distraction types; a contradictory hint can conflict with the ground-truth answer, may change which answer is correct under the new context, or may help some models answer correctly for reasons unrelated to distraction handling. The reported degradation for this scenario therefore conflates genuine robustness with input-semantics changes. The authors should clarify how the contradictory category is constrained so that the original label remains correct, and should report accuracy on a subset of Add Hint samples whose label preservation has been explicitly verified.
minor comments (7)
- [Abstract and §4.1] The abstract states that the evaluation covers "ten state-of-the-art VLMs, including GPT-4o", while Section 4.1 says 14 models are employed and Table 1 lists 14 model rows; these counts should be aligned.
- [§3.1, §3.2] The dataset statistics state 8,100 samples total with 4,000 text-based and 4,100 image-based distractions, whereas Section 3.2 describes four scenarios of 2,000 randomly selected samples each (8,000 in total); the source of the extra 100 samples, and their relationship to the diffusion-inpainted subset of Scenario II, should be clarified so that samples are not double-counted.
- [§6.4, Table 4] The bi-modal results in Table 4 (e.g., Qwen2-VL-2B, Add Hint, "No Img" 57.68) differ from the corresponding Add Hints values in Table 1 (54.45), and the selection of the subset used for Table 4 is not described; this discrepancy should be explained.
- [§4.2, Eq. (2)] The claim that ΔAccuracy(F) is "always less than or equal to zero" is presented as a mathematical fact, but the definition does not guarantee it: a distraction could in principle move a model from a wrong to a correct answer. The non-positive values in Table 1 should be reported as an empirical observation rather than a necessity.
- [§5] The section contains grammatical slips such as "a exact match scores" (twice) and should be copy-edited; similar issues appear in Section 6.1 ("theAdd Hint") and Section 2 ("Mecently", "papr").
- [Table 3] The table caption reads "Exact Math Scores" and should be "Exact Match Scores".
- [Abstract, §1, §3.1, reference [25]] There are naming inconsistencies between the abstract ("GPT-4") and the main text ("GPT-4o"), and between "ProMeAI" in Section 3.1 and "PromeAI" in reference [25]; these should be made consistent.
Circularity Check
No construction-level circularity; the paper's benchmark-contamination and missing-appendix concerns are validity gaps, not circular reductions.
full rationale
The paper does not contain a derivation in which a predicted quantity is algebraically equal to a fitted input or in which a central claim is forced by a self-citation. I-ScienceQA is an empirical augmentation of ScienceQA, and every degradation number in Table 1 is a direct accuracy difference between two evaluations, not the output of a model fitted to those numbers. Section 6.2 explicitly flags that InternVL2 and LLaVA were trained on ScienceQA and that this 'may' inflate performance metrics; that is a data-contamination caveat about external validity, not a circularity, because robustness is defined as an accuracy change rather than as inclusion in a training set. The missing appendix and the unverified assumption that GPT-3.5 and stable-diffusion distractions never change the correct answer (Sections 3.1 and 3.2, Figure 1) are serious verification gaps, but they concern label integrity and benchmark validity, not a self-referential reduction. There are no load-bearing self-citations, no imported uniqueness theorems, no ansatz smuggled in by citation, and no fitted parameter renamed as a prediction. The central empirical finding may be confounded by ScienceQA training overlap, but the paper itself acknowledges this limitation, and the claimed derivation chain is not circular by construction.
Assumptions & free parameters
assumptions (3)
- domain assumption The correct answer to each ScienceQA question is unchanged after adding visual or textual distractions.
- domain assumption The ScienceQA test partition used to build I-ScienceQA is unseen by the evaluated models.
- domain assumption Exact match on a single run is a sufficient measure of reasoning capability and robustness.

Although vision-language models (VLMs) have achieved significant success in various applications such as visual question answering, their resilience to prompt variations remains an under-explored area. Understanding how distractions affect VLMs is crucial for improving their real-world applicability, as inputs could have noisy and irrelevant information in many practical scenarios. This paper aims to assess the robustness of VLMs against both visual and textual distractions in the context of science question answering. Built on the ScienceQA dataset, we developed a new benchmark that introduces distractions in both the visual and textual contexts to evaluate the reasoning capacity of VLMs amid these distractions. Our findings reveal that most-of-the-art VLMs, including GPT-4, are vulnerable to various types of distractions, experiencing noticeable degradation in reasoning capabilities when confronted with distractions. Notably, models such as InternVL2 demonstrate a higher degree of robustness to these distractions. We also found that models exhibit greater sensitivity to textual distractions than visual ones. Additionally, we explored various mitigation strategies, such as prompt engineering, to counteract the impact of distractions. While these strategies improved solution accuracy, our analysis shows that there remain significant opportunities for improvement.
