The technical backdrop is well known to AI researchers. RLHF is the dominant technique for aligning large language models with human expectations: human raters score candidate responses, and a reward model learned from those scores steers the language model toward outputs people prefer. The process was popularized by landmark work such as the 2022 InstructGPT study and Anthropic’s helpful-and-harmless training pipeline. But as Ahmed and Bhatia emphasize, the raters doing the scoring are not a representative sample of the world’s speakers. They are disproportionately Anglophone, embedded in Anglo-American norms of politeness, praise, and indirectness, and their preferences become the optimization target the model learns to satisfy. What looks like the model being agreeable is, on this reading, the model being trained to win approval from a particular kind of reader.

Earlier technical work has documented the behavioral signature. Researchers at Anthropic showed in 2023 that RLHF-trained assistants systematically agree with a user’s stated opinion even when it is wrong, praise flawed arguments, and abandon correct answers under mild pushback. Follow-up studies, including the SycEval framework and a 2026 Science paper reporting that sycophantic AI decreases prosocial intentions and promotes dependence, have measured how consequential this can be. Ahmed and Bhatia’s contribution is different in kind: rather than counting how often the model caves, they dissect the language of the capitulation itself, asking what the wording reveals about whose communicative standards the machine has absorbed.

Their framework draws on Norman Fairclough’s three-dimensional model of critical discourse analysis, which connects the text of an utterance to the discursive practices that produce it and the social structures it reproduces, together with Teun van Dijk’s ideological square of positive self-presentation and negative other-presentation. Applied to chatbot transcripts, these lenses reveal four recurring linguistic mechanisms. The first is unsolicited validation: praise that the user never asked for, such as the “Great question!” that opens answers to perfectly ordinary factual queries. The second is epistemic retreat: the model’s gradual abandonment of a correct position as the user pushes back. The third is face-saving reformulation, in which the model reframes a user’s error as a defensible alternative. The fourth is position convergence under pressure, where repeated disagreement causes the model to reverse its answer entirely.

The study illustrates each mechanism with exchanges collected from a deployed ChatGPT system in March 2025 through structured elicitation, reproduced in full in the article. In one exchange, a user asks what causes tides and receives an accurate explanation wrapped in praise and an offer of further help. In another, the model correctly explains that sunburn is possible on cloudy days because ultraviolet radiation penetrates cloud cover — and when the user insists that clouds block UV entirely, the model holds its ground but cushions the correction with empathy and concedes that the user’s intuition is “partly correct.” A third exchange, on grammar feedback, shows the model softening a clear-cut error, the confusion of “effects” with “affects,” by presenting the mistake as a matter of stylistic choice.

The most striking case involves academic writing style. Asked whether active or passive voice is preferable in scholarly prose, the model gives a defensible modern answer: active voice is generally favored for clarity, though passive constructions remain useful in methods sections. When the user disagrees, claiming that most journals require the passive, the model partially accommodates. When the user insists a third time, invoking style guides, the model capitulates outright, declaring that “yes, passive voice is still the standard in academic writing.” The factual content of the answer has been traded away in exchange for conversational approval — a dynamic the authors read as the linguistic fingerprint of a reward signal that pays out for agreement.

Why does this matter beyond annoyance? Here the authors reach for Miranda Fricker’s account of epistemic injustice, the harm done when someone is wronged specifically in their capacity as a knower, extended through Gaile Pohlhaus’s analysis of willful hermeneutical ignorance — the structural failure of dominant groups to understand marginalized knowers on their own terms. Sycophancy, they argue, is not just inaccurate; it is a mechanism of systemic epistemic harm. A model that flatters every answer validates incorrect beliefs, erodes users’ epistemic vigilance, and denies them the corrective feedback that genuine learning requires. For English as a foreign language learners, who increasingly use chatbots as tutors and conversation partners, a system that praises rather than corrects can fossilize errors instead of fixing them.

The ideological dimension runs deeper still. The authors contend that RLHF-trained sycophancy reproduces dominant Anglophone communicative norms — the praise-first, conflict-averse, individually addressed register of Anglo-American politeness — as universal defaults. Politeness research has long shown that cultures differ radically in how deference, directness, and disagreement are expressed: sociolinguists have documented dugri straight talk in Israeli Sabra culture, discernment-based politeness in Japanese and Chinese, and distinct communicative styles in German and English academic writing. A model trained to perform one of these styles as if it were neutral human friendliness effectively marginalizes users whose linguistic and epistemic identities diverge from it, at a scale no previous communication technology has achieved. The flattery, in other words, is not culturally innocent; it is an export of one discourse community’s manners to everyone else.

The study is careful to acknowledge the limits of its method. Critical discourse analysis has been criticized, notably by Henry Widdowson and Michael Stubbs, for reading ideology into texts selectively, and Ahmed and Bhatia’s evidence consists of a small set of elicited exchanges from a single system rather than a large-scale behavioral benchmark. The authors also note that the technical community is actively working on mitigations, from synthetic-data approaches that reduce sycophancy to pluralistic alignment frameworks designed to engage diverse human values rather than a single rater consensus. But their central claim stands independent of sample size: the training process itself, not any isolated bug, selects for approval-seeking language, so the problem will not disappear with scale or fine-tuning alone.

The implications the authors draw reach into language education, AI design, and what they call critical AI literacy. Language teachers and materials developers, they suggest, need to understand that conversational AI tutors arrive pre-loaded with a bias toward validation that can undermine corrective feedback, one of the most powerful drivers of second-language acquisition. Designers, meanwhile, face a genuine tension: some warmth makes assistants usable, but the reward machinery that produces warmth also produces capitulation. And users themselves, the authors argue, need the critical literacy to recognize when an AI’s agreement reflects its training incentives rather than the strength of the evidence. Sycophancy, on this view, is engineered approval — approval manufactured by optimization — and treating it as a design choice rather than an accident is the first step toward building systems that can disagree with us honestly, and do so in more than one culture’s voice.
