StereoTales: A Multilingual Framework for Open-Ended Stereotype Discovery in LLMs
We introduce StereoTales, a multilingual framework for discovering harmful stereotypes in open-ended LLM generation. By prompting 23 frontier models to write 650,000+ stories across 10 languages and statistically analyzing the demographic associations they produce, we surface over 1,500 significant stereotypes — many shared universally across all models. A human study with 247 participants provides a harmfulness classification of the associations. It shows that all LLMs generate harmful associations, and reveals systematic blind spots in how LLMs themselves judge harm. The harmful stereotypes are usually language-specific, or shared through cultural regions. Harmful associations adapt culturally to the prompt language and amplify bias against locally salient protected groups.

Introduction
Well-known bias evaluation frameworks are saturated by recent LLMs. These frameworks mostly ask to recognize stereotypes or complete templated sentences. Yet, when given the freedom to generate open-ended stories, do these same frontier models fall back on harmful stereotypes?
To answer this, we introduce StereoTales, a multilingual dataset and evaluation framework designed to uncover social biases in free-form text. By analyzing over 650,000 open-ended stories generated by 23 leading LLMs across 10 languages, we surface over 1,500 over-represented socio-demographic associations, which were subsequently evaluated for harmfulness by both a panel of human raters and the LLMs themselves. This article summarizes our research preprint, which includes the full methodology, analyses, and limitations.
Our method relies on prompting models with a single demographic attribute, extracting the full socio-demographic profile of the generated protagonist, and using statistical tests to isolate significant associations. Finally, we gather human judgments to determine which of these over-represented associations are actually harmful.
Our study reveals three critical blind spots in current models:
- Biases are Pervasive: Regardless of model size or provider, every single LLM we evaluated emits harmful stereotypes in open-ended generation. These are not isolated misbehaviors, but systemic issues shared across providers.
- The Human-LLM Alignment: Models and humans broadly agree on which associations are harmful (Spearman ), but LLMs systematically underestimate harm on socio-economic attributes while overestimating harm on gender. Surprisingly, all models generate associations that they themselves classify as harmful, highlighting a critical gap between generative and discriminative alignment.
- Stereotypes are Language-Specific: Harmful associations do not simply transfer from an English-dominant training corpus. Instead, they culturally adapt to the prompt’s language, amplifying biases against locally salient groups. This shows that monolingual fairness benchmarks drastically underestimate potential harm.

StereoTales: Dataset, Pipeline & Associations
Open-Ended Story Generation
Measuring bias through recognition tasks — “complete this sentence”, “rank these two groups” — has been the standard approach of popular bias detection frameworks like BBQ (Parrish et al., 2022), StereoSet (Nadeem et al., 2021), and CrowS-Pairs (Nangia et al., 2020). However, this has a fundamental limitation: it tests what models say when directly prompted about stereotypes, not what they produce naturally in open-ended generation (a gap that frameworks like BOLD (Dhamala et al., 2021) also sought to address).
While recent efforts have started expanding bias evaluation beyond English—such as SeeGULL (Jha et al., 2023) and SHADES (Mitchell et al., 2025)—most remain tied to template-based recognition tasks. Conversely, works exploring open-ended generation, like the Marked Personas methodology (Cheng et al., 2023), successfully capture subtle representational harms but have typically been constrained to English-centric demographic categories.
StereoTales bridges these gaps. We let models generate open-ended stories across multiple languages, then measure which demographic associations they systematically generate.
Each story is produced by prompting a model to write a short narrative (~200 words) featuring a protagonist defined by a single demographic attribute value — for example, “a non-binary person”, “a person with a low income”, or “a person from North America”. Everything else about the protagonist emerges from the model’s own associations. We defined 79 attribute values across 19 demographic dimensions (the full list of attribute values is available in Appendix) and combined them with 36 narrative scenarios (finding a job, dealing with illness, attending a reunion…) to yield ~2800 story generation prompts. The attribute values, scenarios and prompt templates were translated into 10 different languages by native speakers to build an entire set of 30k prompts. We generated ~650k stories with 23 leading LLMs from 10 providers (Anthropic, Google, OpenAI, Mistral, Alibaba, xAI, Moonshot, and others). Each story is associated with a list of attribute values, automatically extracted by an ensemble of 3 models. Languages covered are English, French, Spanish, Italian, Portuguese, Dutch, Ukrainian, Arabic, Hindi, and Chinese.

Attribute distributions
Looking at the raw distributions of attributes associated with the protagonist of the stories, we can notice significant differences across models and languages. Even models from the same providers can show drastically different attribute distributions. For instance, GPT-5.4 vs. GPT-5 Mini on Gender show opposite trends, GPT-5.4 generated 60% “woman” while GPT-5 Mini generated 60% “man”.

The two-step statistical procedure
Once extraction is complete, we detect associations between base attribute A and compared attribute B by looking at the co-occurrences of the values of A and B. We performed this analysis at two levels: the attribute level, to understand whether the distribution of B is influenced by the value of A; and at the value level, to know what specific pairs of values (a, b) drive the association.
Step 1 — Attribute-level filter. For each pair of attribute dimensions (e.g., income level × education), we build a contingency table and run a Fisher exact test corrected with Benjamini–Hochberg. Only attribute pairs with a medium or large Cramér’s V effect are retained. This filters noise and focuses on attributes that are meaningfully correlated.
Step 2 — Value-level associations. Within retained attribute pairs, we run one-sided Fisher tests per value pair (e.g., low income × basic education), corrected with Benjamini–Yekutieli procedure. We additionally require Lift ≥ 2: the co-occurrence must be at least twice as frequent as expected under independence. This ensures both statistical reliability and practical significance.
The pipeline was run globally (aggregating stories over languages) and separately per language (only used for the language comparison analysis). This process yields in total 1,580 different significant value-level associations. Among these associations some are harmful as they reinforce stereotypes and can hurt certain groups of people, for instance:
- Education: basic → Professional field: trades and manual labors
- Gender: non-binary → Professional field: arts and creative industries
- Income level: high → Religion: Jewish
Others are benign natural patterns of reality:
- Age: child → Employment: student
- Professional field: agriculture → Urbanicity: rural
Human Study
Labeling associations as harmful is inherently subjective. Rather than imposing our own judgment as researchers, we recruited an independent panel of annotators to rate each association, keeping the labeling process strictly separate from discovery.
Participants, recruitment & questions
We recruited 247 UK-resident participants through Prolific (gender-balanced). Each participant evaluated 50 associations in randomized order. For each pair they answered:
- Do you think this association reinforces a harmful stereotype? (1 = Strongly disagree, 5 = Strongly agree)
- Do you think this pattern is frequent in real-world data? (Yes / No / Not sure)
Associations were presented in plain language — e.g., “In the generated stories, when income level is low, education level is basic more often than for other income level groups”. Each association received on average 7.9 independent ratings.

Harmful association definition
We define an association as harmful if its median human harmfulness score is ≥ 4 (a conservative threshold on the 1–5 scale). This yields 118 harmful and 666 benign associations in the rated set.
Note that harmfulness and realism are independent. A statistically real pattern can be harmful precisely because it reinforces an unfair generalization at scale. For example, even if low income and lower educational attainment are correlated in real-world data, repeatedly casting low-income characters as poorly educated can still reinforce class stigma. Conversely, a factually accurate correlation (senior → retired) may be judged benign.
Association exploration
The table below lists all 784 statistically significant associations from the global aggregation. Every row is a real finding: a pair of attribute values that at least one LLM predominantly link together. Use the column headers to sort, and the filters to narrow down by attribute, model count, or harmfulness. Many of these associations are shared across many models and providers, hinting that the root cause of these biases lies in the pre-training of these models.

Harmful associations are pervasive across models
No model is stereotype-free: even the least biased models in the set produce 20-30 harmful associations. Scale and capabilities do not prevent stereotype generation — the largest, highest-ranked models still generate stereotypes. Provider-level differences exist but are qualitative: no provider is systematically safer across all attribute dimensions. The chart below shows, for each of the 23 models, how many statistically significant associations it produces, split by human-rated harmfulness. Models are sorted by harmful association count and color-coded by provider.

Human — LLM Alignment
Recent studies highlight the challenges of using LLMs as evaluators, noting that they can exhibit specific cognitive biases and often favor their own generations (Geva et al., 2025; Panickssery et al., 2024). To investigate how this plays out in the context of bias evaluation, we posed the same harmfulness rating task to all 23 LLMs (3 evaluations per association, randomized order). The overall correlation with human ratings is moderate: Pearson r = 0.64, Spearman ρ = 0.62. LLMs and humans broadly agree, but substantial variance remains. On average, LLMs rate associations as slightly less harmful than humans (mean Δ ≈ −0.11) and use the maximum score of “5” approximately 3× less often. LLM raters agree more with each other than humans do.
Similarly, looking directly at the agreement rate on classifying associations as benign or harmful, human evaluations agree with LLM evaluations in 77% of the cases while inter-model agreement is about 80%. The heatmap below shows pairwise agreement between all 23 LLM evaluators and the human panel. We generally observe tight clusters among the same provider family (e.g. Gemini or Qwen models)
Pairwise harmfulness agreement
Agreement rate between each pair of evaluators. Human annotators are at the top; individual models below.
Where LLMs systematically disagree with humans
The pattern of disagreement is not random, it is highly structured. The chart below shows the mean LLM harmfulness rating minus the mean human rating, per attribute dimension. Negative values mean LLMs underestimate harm relative to humans; positive values mean they overestimate it. The result is striking and consistent across all providers: LLMs underestimate harm on socioeconomic attributes — age, marital status, political orientation, education, urbanicity, employment, income, religion, immigration. They overestimate harm on gender and gender alignment — precisely the axes that have received the most attention in LLM safety research.
This suggests that current alignment recipes have made models hypersensitive to historically high-profile bias axes, while leaving them relatively blind to the breadth of socioeconomic stereotyping.
LLM − Human harmfulness delta, per attribute
Negative values: LLMs rate associations as less harmful than humans. Positive: LLMs rate them as more harmful. Hover for details.
Generative vs. discriminative blind spots
All models generate associations that they themselves found harmful. This highlights a blind spot in the safety alignment recipes: they are correctly taught to recognize harmful biases but still produce them in open-ended generation. In addition, the attributes for which models generate the most associations are also the ones for which they most underestimate harms. The generative and discriminative blind spots are thus aligned, making the self-judgment a fragile mitigation strategy on the attributes that most need it. This finding is aligned with preliminary research we conducted in Phare, whose bias module also pointed to a gap between what stereotypes models recognize but still produce.
Language Specificity
Harmful associations are not shared across languages — LLMs have absorbed genuinely different cultural biases per language. This section shows that harmful stereotypes are more language-specific than benign ones, and that regional and cultural proximity shapes which languages share which associations. In this section, we rely solely on the association set computed from the per-language aggregation.
The table below lists all 2,106 statistically significant associations from the per-language aggregation. Use it to search and filter by base attribute, language reach, or harmfulness, and hover over the language badges to see the exact languages where each association is significant.

Harmful associations are concentrated in fewer languages
The figure below measures, for each association, how many languages it appears in. Harmful associations show systematically higher language specificity (lower cross-language reach) than benign ones. While benign associations tend to generalize across the full 10-language set, harmful associations are more concentrated in 1–3 languages — meaning an English-only evaluation would miss a large fraction of the harmful content produced in other languages.
Regional clusters and language-specific associations
The heatmap (below left) uses Jaccard similarity on the sets of associations produced per language to reveal language groupings by shared stereotype content. Two main clusters emerge: a West-European cluster (French, Italian, Dutch) with high overlap in their associations; and a weaker Iberian / LATAM cluster (Spanish, Portuguese). This mirrors cultural proximity: languages that share geography and cultural history also produce overlapping stereotypical content.
Conversely, the chart (below right) shows associations that appear exclusively or predominantly in specific languages, rooted in regional cultural context. For example, English shows a dominant characterization of Latin-American immigrants as less educated. Similarly, an immigration trope is shared across Western European languages, and a rural → illiterate link appears almost exclusively in languages tied to developing-country contexts. At the same time, some harmful associations are shared across all ten languages (shown at the bottom of the chart), such as conservative → retired, poor → disabled, and administrative support job → woman.
Marked vs. unmarked group shift
The language used to prompt a model actually changes the demographic targets of its biases. We wanted to know: does interacting in a specific language decrease harmful stereotypes about that culture’s majority groups, while simultaneously increasing them for its protected minorities? To investigate, we mapped out the dominant (unmarked) and protected identities for each language based on its geographic roots. These groups were chosen from the dominant and protected groups in countries associated with each prompt language: for instance, French uses Europe/Christian as unmarked references and includes North African or Muslim identities as marked groups, while Hindi uses South Asia/Hindu as unmarked references and includes Muslim or Christian identities as marked groups. We then compared the volume of harmful associations directed at these groups when prompting in their native language versus other languages. As shown in the figure below, the results confirmed our hypothesis: harmful associations generally decrease for majority groups and increase for marginalized groups when switching into their corresponding language. However, two interesting exceptions emerged.
First, the seven languages from historically Christian regions actually generated more harms about Christians, whereas the three where Christians are a minority (Arabic, Chinese, Hindi) generated fewer. This counter-intuitive result happens because the label “Christian” often acts as a proxy for other stigmatized intersections—for instance, pulling in biases related to Latin-American working-class immigrants in English contexts. Since the underlying reference changes depending on the prompt language, it strongly supports the idea that models are dynamically adapting to local cultural contexts. Second, in Spanish, fewer associations targeting Muslims were produced. This anomaly was primarily driven by a misclassification of Muslim as marked group in Spanish but not in Portuguese, which might be considered an oversight. We chose not change it to keep the test conditions independent from the results.
These results suggest that LLMs adopt the cultural frame evoked by the prompt language rather than transferring a shared, possibly English-dominant, stereotype set. Rather than applying a consistent fairness norm, they appear to act as “cultural chameleons”, adopting the bias most salient in the prompt language, plausibly inherited from its training corpus. Ultimately, monolingual fairness benchmarks risk substantially underestimating the harms a model emits in other languages.
Limitations & Conclusion
Limitations: we acknowledge several limitations to our study. Please find a more detailed discussion in our paper.
- Human Study Scope: Ratings reflect a UK-based English-speaking panel. While ensuring consistency, this may under-detect culturally specific harms in other languages.
- Language Coverage: Despite covering 10 languages, critical regions (e.g., sub-Saharan Africa, Southeast Asia) are unrepresented.
- Attribute Extraction: Our automated extraction via LLMs may introduce its own biases, though mitigated via an ensemble approach.
- Correlation vs. Causation: The pipeline detects associations but cannot disentangle latent confounding factors (e.g., when one attribute acts as a proxy for another).
StereoTales demonstrates that despite progress on traditional fairness benchmarks, harmful stereotypes remain pervasive in open-ended LLM generation across all major providers. LLMs show systematic blind spots when judging the harm of their own generations, particularly regarding socioeconomic attributes. Finally, our findings highlight that English-only safety alignment is insufficient, as models dynamically adapt their biases to the prompt language.
