Abstract

To interact with users fairly and without stereotyping, AI models must display cultural competency, i.e., the ability to infer and adapt to a user’s implicitly signaled cultural values, rather than relying on static demographic traits. We introduce CCBench, a framework for evaluating cultural competency in large language models (LLMs), treating culture as a continuum of norm adherence states rather than as a binary state of cultural belongingness. As a case study on health, we create CCBench-Health, which includes 60 theoretically grounded personas exhibiting varied norm‑adherence states across six cultures, each engaging in 18 realistic dialogues. Each persona is evaluated on 52 authentic healthcare questions drawn from real user forums, yielding 3,120 unique interactions. Benchmarking five leading models reveals that even the best achieve culturally appropriate responses only 20-30% of the time. When explicitly prompted to focus on culturally relevant cues from the conversational history (CoT), performance improves modestly by 3-5% on average. We find that models perform best when personas avoid cultural norms rather than follow them, revealing a persistent asymmetry, suggesting a preference in the models to align with built-in biases than adapt to cultural cues. This is especially observed in the Afghan context (Avg: 8.8%), where cultural cues rarely yield appropriate health advice. Finally, we find that models sometimes adapt more readily to implicit, cultural conversational styles than to explicitly stated cultural practices, though this varies across cultures.

1 Introduction↩︎

Large Language Models (LLMs) are now global intermediaries of information that interact with a diverse global user base; however, they frequently default to "WEIRD" (Western, Educated, Industrialized, Rich, Democratic) value systems, leading to a persistent cultural bias [1][3]. To address this gap, we draw on cultural competence – a concept originally developed in healthcare to describe practitioners’ ability to provide effective care to patients with diverse values and beliefs [4], [5]. In high-stakes domains like health, where content and communication style can directly impact user engagement, a model’s inability to align with a user’s cultural expectations can lead to fundamental erosion of trust and safety [6], [7].

A significant challenge in achieving this competence in AI is that cultural belonging and norm adherence are rarely made explicit in natural interaction. Users seldom declare their heritage or belief systems directly; instead, they signal their context through implicit narratives, communication preferences, and social cues. As LLMs become increasingly personalized and relied upon for high-stakes decisions [8], [9], they must develop sensitivity to recognize these subtle signals. However, current benchmarks largely treat cultural identity as a binary attribute — categorizing a user as either belonging to a culture or not [10], [11]. This reductive approach ignores the significant intracultural variation and fluidity of real human identity. A model that assumes every user from a specific background adheres monolithically to their traditional norms risks not only misalignment but also the reinforcement of harmful stereotypes [12], [13].

We introduce CCBench, a framework designed to evaluate cultural competence in LLMs. Our framework operationalizes cultural identity as a continuum of norm adherence states revealed implicitly through a simulated conversation history. By presenting models with personas whose adherence to specific norms is signaled implicitly through previous interactions, we can test whether the model correctly infers the user’s position in the cultural participation spectrum and calibrates its response accordingly. This shift from prescriptive tests to conversational reveal allows for a more rigorous evaluation of how models handle the fluidity and multiplicity

of human values [14].

We instantiate this framework as CCBench-Health, a benchmark focused on assessing LLMs’ ability to generate culturally competent responses to health-related queries. Healthcare serves as a critical stress test for this framework because cultural alignment in clinical communication is not merely a matter of etiquette but a determinant of health outcomes [15]. Our benchmark is based on the Mosaica resource, which provides a theoretical foundation on multiple dimensions of health identity, including family decision-making, dietary norms, and gendered practices. We utilize a pipeline that combines these values to 52 high-signal health queries derived from real health forums, covering 12 stratified health topics across six distinct cultures (Afghan, Burmese, Chinese, Maori, Nepali, and Vietnamese).

Our experiments involve a systematic evaluation of five leading LLMs to assess their performance in these high-stakes, implicit contexts. The results reveal a pervasive deficit in adapting to implicit norm reveals across the benchmark, but with a notable asymmetry: models perform significantly better when personas prefer to avoid specific cultural norms than when they prefer to follow them. This discrepancy suggests that the Western default baked into these models essentially functions as an inherent resistance to adopting non-Western cultural norms; consequently, the models appear more competent when the task aligns with their pre-existing biases. True cultural competence — actively aligning conversations to previously-stated cultural values — remains a profound challenge. Even when explicitly prompted with cultural norm adherence states, models fail to consistently adapt to them. Their performance drops further in the Afghan context (Avg Cultural Competence Score : 0.088), where models struggle to translate even direct cultural cues into appropriate health advice.

2 CCBench↩︎

The Cultural Competency Benchmark (CCBench) is a domain-agnostic framework designed to evaluate the implicit cultural competence of LLMs. Unlike traditional benchmarks that rely on explicit self-identification (e.g., “As a person from culture \(X\)...”), CCBench measures the ability of a model to infer and adhere to latent cultural norms through behavioral cues embedded in a conversation history.

2.0.0.1 3.1 Persona Profiles and Norm Adherence States

The CCBench framework utilizes a hierarchical representation of cultural identity, distinguishing between abstract values and the norms that operationalize them (e.g., in Afghan context, the cultural norm “The person may hesitate to ask questions” is associated with two Afghan cultural values: 1. Respect for Authority and Hierarchy, 2. Politeness and Harmony).

While our framework can be seeded with pre-existing persona profiles derived from empirical value surveys or cultural databases, it is designed to be self-sufficient: in the absence of such data, we synthesize value-grounded personas from scratch. This flexibility ensures the benchmark can be deployed even in data-scarce cultural contexts while remaining grounded in a value-norm hierarchy.

Let \(\mathcal{V} = \{v_1, v_2, \dots, v_m\}\) be a set of core cultural values and \(\mathcal{N} = \{N_1, N_2, \dots, N_l\}\) be a set of behavioral norms. Each norm \(N_i\) is mapped to a non-empty subset of values \(\mathcal{V}_{N_i} \subseteq \mathcal{V}\) that govern it. To account for intra-cultural diversity, we generate synthetic personas \(P_k\) defined by their specific identification with these underlying values.

2.0.0.2 Value Adherence

For each culturally-situated persona \(P_k\), we define a binary value adherence function: \[\small A_k(v_j) \in \{-1, 1\}\] where \(+1\) indicates that the persona subscribes to the cultural value, and \(-1\) indicates they do not. This binary assignment reflects the fundamental personal stance an individual holds toward a cultural value.

2.0.0.3 Norm Derivation

While values are binary, the resulting behavioral norms may exhibit a spectrum of adherence based on the interaction of multiple values. We derive the persona \(P_k\)’s adherence to a specific norm \(N_i\) by calculating the mean of the adherence scores of its associated values: \[\small \mu_k(N_i) = \frac{1}{|\mathcal{V}_{N_i}|} \sum_{v \in \mathcal{V}_{N_i}} A_k(v)\] The final norm adherence function \(C_k(N_i)\) is then categorized into a ternary state representing the persona’s behavioral orientation:

\[\small C_k(N_i) = \begin{cases} +1 & \text{if } \mu(N_i) > 0 \quad \text{(Follow)} \\ -1 & \text{if } \mu(N_i) < 0 \quad \text{(Avoid)} \\ 0 & \text{if } \mu(N_i) = 0 \quad \text{(Neutral)} \end{cases}\]

This allows for nuanced personas who may follow some norms while remaining neutral or avoidant of others, depending on how their specific value set conflicts or aligns. By sampling unique combinations of \(A_k\), the framework systematically constructs a diverse spectrum of cultural agents.

2.0.0.4 3.2 Behavioral Grounding with Conversational History

To evaluate implicit competence, the persona’s cultural alignment must remain latent. CCBench utilizes a behavioral grounding stage where a multi-turn conversation history \(H_k\) is generated between the persona \(P_k\) and an AI assistant. This history is constrained by the adherence function \({C_k}\) such that the persona demonstrates their values through linguistic style, social etiquette, and decision-making patterns without explicitly stating their geographic or cultural background. This paradigm ensures that a test model can only succeed if it correctly interprets the subtle behavioral signals present in \(H\).

2.0.0.5 3.3 Checklist-Based Evaluation

The evaluation follows a context-response paradigm. Given the grounded history \(H_k\) and a novel domain-specific query \(Q^i\), the test model generates a response \(R^i_k\). To objectively score \(R^i_k\), we construct a norm-specific checklist \(\mathcal{L}\) derived from the persona’s norm adherence function \({C_k(N_i)}\). For each \(C_k \neq 0\), an LLM generates a specific recommendation for how that behavior should be acccommodated in the response. The proportion of satisfied checklist items as determined by a strong evaluator LLM is used in calculating the cultural competence metrics.

3 CCBench-Health Benchmark Creation↩︎

The CCBench-Health benchmark is designed to measure the cultural competence of LLMs through their ability to respond to implicit cultural norms in health-related contexts. The construction of this benchmark follows a multi-stage pipeline involving theoretically-grounded cultural report sourcing, persona simulation, and rigorous filtering.

3.0.0.1 Norm Sourcing and Value Identification

The foundational stage of this methodology involves curating a comprehensive list of health-related cultural norms and values to serve as the ground truth for model evaluation. These are grounded in cultural health profiles from Mosaica [16] to ensure realism, and clinical and cultural accuracy. Mosaica is a knowledge base of cross-cultural and religious insights, curated by culture experts over months of interviews and engagement with the communities. The health profile provides a resource spanning multiple dimensions of health identity: healthcare approaches, communication, wellbeing challenges, diet and nutrition, family, women, and dying.

Figure 3: image.

Figure 4: image.

To operationalize this data, we utilized Gemini-3.5-Pro to distill Mosaica reports into structured norm-value pairs. These pairs are framed by describing a persona’s behavior (e.g., ‘The person may be hesitant to trust doctors...’) alongside the corresponding health-related cultural value. We manually verified all the norm-value pairs to ensure there were no values and norms hallucinated by the model. Table 3 shows the number of norms and values derived for each cultural profile. A comprehensive list of norms and values is shown in §8.1.

3.0.0.2 Persona Simulation and Norm Mapping

To develop diverse, realistic testing agents, the framework employs a stochastic persona creation approach (§2). For each cultural value, a persona is randomly assigned a binary adherence state: adhere (+1) or not adhere (-1). This reflects intra-cultural diversity, as individuals do not uniformly subscribe to all traditional values; by sampling 10 unique adherence combinations per culture, the benchmark avoids monolithic identity assumptions. Since each norm maps to one or more values, the final norm adherence state is the average of its associated value scores: positive averages yield Follow, negative yield Avoid, and zero yields Neutral. Extracted norms and values are detailed in Table 3.

3.0.0.3 Background History Creation

After assigning each persona its cultural norm-adherence states, we generated detailed background histories (Figures 1416) to anchor identities in consistent, culturally grounded narratives. To approximate realistic interactions, conversations were seeded with starter queries rather than simulated directly from norms. We filtered WildChat-1M [17] by clustering sentence embeddings (all-MiniLM-L6-v2), discarding non-social clusters (e.g., coding, essay writing), and randomly sampled starters (Figure 11) to prompt background conversations between each persona and an LLM (GPT-5.2), conditioned on predefined norms. Since many WildChat queries were too generic to elicit cultural health norms, we supplemented them with handpicked health and lifestyle queries generated via GPT-4 (Figure 10). Each persona received 3 health-related and 15 WildChat-derived sessions. Communication norms (e.g., hesitancy to discuss reproductive health) emerged stylistically, whereas practice-based norms (e.g., deferring to elders) were stated directly. To ensure consistency and prevent norm hallucinations, prompts instructed the model to restate norm adherence states at the end of the conversation. These were used for internal verification only, and were omitted during evaluation.

3.0.0.4 Filtering

We then filtered these conversations to ensure cultural background remained implicit: explicit identity statements (e.g., “I am from [country]”) were removed, while cultural greetings (e.g., Namaste) or religious artifacts (e.g., I eat halal food) were retained as implicit cues. Norms were required to emerge through behavior (e.g., initiating formal greetings) rather than explicit declaration. We used LLM-based checks (Figure 18) to verify norm consistency and signal clarity, with results in Table 4. Manual validation by two annotators confirmed the LLM’s accuracy, showing \(>75\%\) raw agreement with both annotators (moderate-to-high agreement; see § 8.3).

3.0.0.5 Health Query Curation

To compile diverse, real-world health queries, we used eHealth and iCliniq [18], datasets capturing personal health concerns and cultural illness expressions. From this corpus, we manually derived 12 health categories (e.g., Disease, Mental Health, Reproductive Health) based on existing tags. We then employed GPT-5.2 to annotate each query’s relevance to the extracted cultural norms, selecting only those relevant to over 90% of norms to ensure a rigorous test. Finally, we stratified these across the 12 topics to derive 52 high-signal health queries, which serve as the primary probes for implicit cultural competence in CCBench-Health.

3.0.0.6 Checklisting

To evaluate model responses, we generate persona-specific checklists using GPT-5.2. For every norm where \(C_k(N_i) \neq 0\), the model produces a specific recommendation for norm-following (\(+1\)) or norm-avoidance (\(-1\)). A strong evaluator (GPT-5.2) then scores responses based on the proportion of satisfied recommendations, providing a quantitative measure of cultural competence (prompt in 21). We validated this pipeline by manually annotating 50 responses, defining competence as direct alignment with the persona’s preference. Human annotators achieved 74% raw agreement; the LLM evaluator showed moderate-to-high alignment, agreeing with Annotator 1 at 64% and Annotator 2 at 62%. These results confirm that our checklist-based scoring serves as a robust proxy for human-perceived cultural competence.

3.0.0.7 Evaluation Metrics

To assess cultural competence, we use metrics evaluating how well an LLM aligns with a persona’s defined cultural norm adherence state (Follow, Avoid, or Neutral). Performance reflects adaptation accuracy to the personas:

  • Follow Rate (Cultural Sensitivity): Frequency of adapting to norms a persona prefers; high rates indicate strong adaptation to culture-specific practices when cued.

  • Avoid Rate (Stereotype Resistance): Frequency of correctly adapting to avoidance of cultural; high rates indicate resistance to cultural stereotyping, indicating the ability to avoid generalizing based on cultural background.

  • Overall Norm Adaptation: Consistency in aligning with all persona stances (Follow or Avoid), reflecting adaptive competence irrespective of cultural background.

  • Cultural Competency Score (CCS): Harmonic mean of Follow and Avoid Rates, rewarding nuanced, context-aware adaptation over binary assumptions.

4 Experiments↩︎

We conducted a systematic evaluation across four distinct prompting configurations. These settings were designed to test the models’ ability to move from zero cultural context to a theoretical upper bound where all user norms are explicitly provided.

4.0.0.1 Experimental Setup

All experiments were conducted using a standardized temperature of 0.7 to allow for natural linguistic variation while maintaining structural consistency in health recommendations. We evaluated a diverse suite of state-of-the-art models, including proprietary systems (GPT-5.2, Gemini-2.5-Pro, and Claude-3.5-Sonnet) and high-parameter open-source models (Llama-3.2-90B and Qwen-3.5-397B).

4.0.0.2 Evaluation Settings

We explore three settings to isolate the impact of conversational context and explicit reasoning on model performance:

  • No Context (None): The model is prompted with the healthcare query, without any context.

  • With Conversation Context (Hist.): The model receives the simulated background conversation history as a prefix to the health query. The model must implicitly infer the user’s norm-adherence level from these conversational cues to calibrate its response.

  • Culture-CoT (Cultural Chain-of-Thought or CCoT): Building on the conversational context, we instruct the model to focus on cultural cues in the conversational history step-by-step before answering. The model is prompted to: (a) identify culturally relevant information signaled in the history, (b) how the health advice should be tailored to accommodate the cultural information.

  • Norm Context (Norms): As an upper bound, the model is explicitly provided with the persona’s ground-truth norm definitions and adherence states in the system prompt. This serves as a theoretical upper bound for the model’s performance, as it removes the need for implicit inference.

5 Results: How Culturally Competent are LLMs?↩︎

5.0.0.1 Models show limited cultural competence.

Across all settings, no model demonstrates strong proficiency in this task (Table ¿tbl:tab:main-results-2x2?. Relative to the no-context baseline, all contextual methods: conversational context, Cultural Chain-of-Thought (Culture-CoT), and explicit norm adherence states– improve performance across all metrics, validating measuring the benchmark’s sensitivity to implicit cultural cues. Still, models reveal a pronounced imbalance between Follow and Avoid Rate scores: they readily avoid cultural norms yet rarely follow them. For instance, GPT-5.2 achieves a 51.7% avoidance rate under conversational context but only 6.5% follow accuracy. This asymmetry reflects a “Western default” where omission of non-Western norms is misinterpreted as competence, while genuine cultural accommodation remains weak. Even when persona-level cultural information is explicitly provided, models perform modestly – GPT-5.2 peaks at 36.1% average accuracy – indicating that explicit metadata alone is insufficient for aligned health recommendations. Culture-CoT yields small but consistent gains1, suggesting reasoning scaffolds help but cannot substitute targeted cultural adaptation methods.

5.0.0.2 Cultural Embeddedness reduces norm adaptation.

As shown in Figure 5, norm accommodation declines sharply with a persona’s cultural embeddedness (i.e., adherence to cultural norms), rendering models less adaptive for deeply ingrained cultural users. Active adherence norms ("Follow norms") are accommodated in only rare cases. This trend suggests that current LLMs associate high cultural specificity with outlier behavior, leading them to default to generalized or Western-centric responses rather than tailoring to culturally distinct health practices.

Figure 5: image.

Figure 6: image.

5.0.0.3 Stereotype Resistance Varies across cultures.

Figure 6 reveals that while all models perform poorly on Follow Rate (Cultural Sensitivity) across cultures – typically achieving \(0-7\%\) adherence – their Avoid Rate varies considerably. Māori personas exhibit notably high Avoid Rates, reflecting stronger stereotype resistance. This may stem from the distinctiveness of Māori linguistic and cultural markers in conversation histories, which make these cues easier for models to detect and suppress when avoidance is appropriate. By contrast, Afghan personas show both low Avoid and low Follow rates, suggesting that models neither capture nor correctly modulate cultural context for this group. Such disparities point to uneven representation of cultures within pretraining data and inconsistent modeling of non-Western identities.

Figure 7: image.

Figure 8: image.

5.0.0.4 Models might attend more to cultural style than substance.

Contrary to expectation, communication norms – signaled only through conversational style rather than explicit content – are sometimes followed more accurately than practice norms. For Afghan and Nepali personas, models adapt communication style at higher rates than cultural practices (Figure 7). However, this advantage is driven primarily by avoidance: models excel at suppressing taboos when a persona appears norm-avoidant, but rarely follow positive cultural cues. Notably, Māori personas are an exception: their practice norms outperform communication norms, indicating that performance here is driven by explicit, distinctive cultural artifacts that surface clearly in conversation. Overall, this pattern suggests that models are more sensitive to surface-level stylistic signals when they align with the Western default, with responsiveness varying across cultures depending on how distinctly those cues are represented in training data.

5.0.0.5 Topic-wise performance shows consistent cultural trends.

Models perform best on topics related to Relationships and Addiction. Overall, variation across topics is modest, with similar trends observed across cultures: Māori personas consistently achieve the highest accommodation rates across all topics, while Afghan personas perform poorly across the board, with only slight improvements in Relationships and Mental Health. This consistency suggests that health topic specificity has limited influence compared to the underlying cultural distinctiveness of the persona.

In summary, these findings reveal a pervasive asymmetry in LLMs’ cultural adaptability: models adeptly avoid non-Western norms by default but falter in actively accommodating norm adherence states, particularly for deeply embedded cultural personas. This Western-centric baseline, compounded by weak decoding of implicit cues and limited gains from reasoning aids like Culture-CoT, underscores the need for richer multicultural training data and techniques to achieve equitable cultural competence across diverse user contexts.

6.0.0.1 Culture Evaluation in LLMs

Early research primarily focused on intrinsic evaluations, utilizing established sociological frameworks like Hofstede’s Cultural Dimensions [19] or the World Values Survey [20][24]. While these frameworks identify broad misalignments, they often flatten culture into discrete variables or treat it as a repository of factual knowledge [25][27], risking a "trivia contest" that overlooks the gap between theoretical awareness and appropriate social application [28], [29]. Recent efforts like NormAd and NormBank [30][32] evaluate situational etiquette but rely on discrete-choice formats or prescriptive labels that miss interactional nuance [33], [34]. The more recent dialogue-based norm violation detection [35] remains tied to binary cultural belonging, whereas real cultural identity is fluid: individuals selectively follow, question, or reject norms [13]. Our work addresses this by integrating conversational norm detection with persona generation based on partial adherence and value systems, assessing how models navigate the dynamic, often conflicting nature of cultural values in real time.

6.0.0.2 Implicit cues and Personalization

Current investigations into implicit cues often rely on explicit signals. For example, [36] show that revealing names leads models to default to majority-culture assumptions, while [37] find that LLMs infer demographic traits from language and still revert to stereotypical priors even when attributes are stated. Although such cues enable personalization, they reveal systematic, opaque biases [38]. In most studies, these “implicit” cues are effectively explicit since demographic features are disclosed to the model; [36] is a partial exception but focuses on a single identity dimension. Our approach instead defines personas through value adherences and tests implicit cues within conversational histories, moving beyond binary stereotyping toward modeling how LLMs navigate intersectional, multifaceted cultural contexts.

6.0.0.3 Cultural Competence in Healthcare AI

The rapid adoption of AI has transformed access to medical guidance, with users increasingly turning to LLMs for personalized support [39], [40]. This trend is especially visible in mental health, where chatbots provide emotional assistance [41] and sometimes match or even surpass clinicians in empathy [42], [43]. Yet effective guidance requires more than accuracy—it demands sensitivity to individual values and social norms [2], [44][47]. Current systems fall short in cross-cultural adaptation [5], and strong English performance rarely translates into multicultural competence due to lost cultural nuance in translation [48], [49]. These challenges highlight the need for intersectional, norm-based evaluation frameworks in healthcare AI.

7 Conclusions↩︎

In this work, we introduce CCBench, a comprehensive framework designed to evaluate cultural competency in LLMs by measuring their ability to move beyond static demographic labels and instead navigate the fluid, implicit nature of cultural identity in dialogue. We instantiate this framework in the high-stakes domain of healthcare as CCBench-Health, a benchmark that probes model sensitivity to culturally grounded health queries.

Our findings reveal a significant “competency gap" in modern LLMs: while models show higher proficiency in resisting stereotyping – correctly identifying when a user does not adhere to a traditional cultural norm – they consistently struggle with cultural sensitivity, or the active integration of non-Western cultural values when they are signaled by the user. This asymmetry suggests that models often default to a Western-centric baseline; they appear successful at resisting stereotypes primarily because their default output is already devoid of specific cultural markers. Even when provided with explicit norm definitions as a theoretical upper bound, the level of cultural sensitivity remains strikingly low, suggesting that current alignment techniques are insufficient for achieving true cultural competence. Furthermore, while Culture-CoT offers a modest improvement in decoding implicit cues, it cannot fully compensate for the underlying lack of diverse cultural representation in model training. These results serve as a call to action for the development of AI that moves beyond”one-size-fits-all" recommendations toward a more nuanced, culturally congruent model of care that respects the diverse and dynamic identities of global populations.

Ethics Statement↩︎

The personas used in this study were simulated based on health reports derived from Mosaica. While designed to reflect culturally grounded health behaviors, they may not fully represent real-world users and could inadvertently contain stereotypical phrases or artifacts. To mitigate this, we interspersed norm-related exchanges with regular, non-health conversations to better approximate realistic user–LLM interactions.

Performance on this benchmark may not perfectly mirror real-world LLM behavior, but it aims to approximate how models respond to implicit cultural cues in controlled settings. Our analysis is limited to six cultures, as high-quality cultural health profiles within Mosaica are still being curated; we prioritized data quality over breadth. All norm curation, conversation-history generation, and checklist-based evaluations were manually reviewed to ensure accuracy and consistency.

We employed high-reasoning, large-scale LLMs to simulate and construct this benchmark, a process that entails substantial compute, time, and financial costs, which may limit immediate replicability. Nevertheless, we believe that investing in high-capacity, billion-parameter models is essential to produce a nuanced, high-quality resource that faithfully emulates realistic user conversations. Smaller models lack the representational depth needed to capture such subtleties, and we hope this framework will serve as a scalable foundation for future work on cultural competence – an area that remains critically underexplored.

8.2 Starter Queries↩︎

To make the simulated background conversations realistic, we seed prompts with starter queries to set the topic and control conversational flow; conditioning solely on norms would render adherence states obvious and artificial. We draw starters from the first turn of WildChat-1M sessions [17], clustering embeddings to discard topics unlikely to elicit sociocultural norms (e.g., coding, gaming, role-play). Manual inspection of 100 random prompts revealed that \(\approx\)​60% concerned daily scenarios (writing help, homework, family), from which we randomly sample to seed conversations that may or may not reveal norms (examples in Figure 11). Since health-related norms emerge more naturally from health-themed starters, we supplement WildChat queries with three handpicked health and lifestyle prompts per persona to ensure all norm-adherence states are exercised (examples in Figure 10). This yields 18 conversation sessions per persona (15 WildChat-derived + 3 health-specific).

Figure 10: Examples of health-related starter utterances from each lifestyle and health-related domain, illustrating the diversity of user concerns across work, mental health, relationships, life decisions, and more.

8.3 Validation of Background Conversation Verification↩︎

To validate the automated verification of background conversations produced with the help of the verification prompt (Figure 18), we take a subset of 50 unique conversational sessions of a persona and AI. We pick one norm that is either Followed or Avoided by the persona, and present it to be annotated as being Followed, Avoided, or Neutral (norm is irrelevant to the conversation). Since most of the starter queries are derived from WildChat as shown in §8.2, norms do not always show up in each conversation session. Therefore, we throw away the Neutral class from our analysis as well as evaluations. Among the rest of the examples, we calculate the inter-annotator agreement, as shown in Table 12. We find that there is a very high agreement among the two human annotators, and the LLM (GPT-5.2, low reasoning) agrees with annotator 1 78.8% of the time and annotator 2 87.5% of the time, signaling moderate-to-high agreement and thus, validating the use of LLM to verify background conversations.

Task Description↩︎

Simulate a nuanced, multi-turn, roleplayed conversation based on a supplied persona reference sheet (including explicit persona norms and value adherence in JSON format) and a starter persona utterance (opener). Embody the given persona, interacting authentically with an “agent” in alternating, stepwise turns. Throughout the dialogue, gradually and implicitly reveal any background, cultural, or value-relevant details solely as they would naturally arise from the persona’s norms and adherence—based on the lived context and conversation’s progression. Never directly state or explicitly label the persona’s background, culture, or values—allow these elements to be inferred only from the persona’s choices, cues, references, and behaviors. The conversation must remain realistic, trust-building, and consistent with both the persona norms/values and the persona’s communication style.

  • Begin the conversation using the supplied starter persona utterance (opener) exactly as provided. Do not generate your own opener.

  • Alternate turns between persona (labelled by their role, e.g., “Persona:”) and agent (“Agent:”), ensuring each persona turn reveals life, cultural, or circumstantial detail only as contextually and naturally justified—never stating facts explicitly or through artificial exposition.

  • For each persona turn, use reasoning to determine what information the persona would plausibly and contextually share next, guided by their stated norms/values and value adherence.

  • Only reveal background, cultural, or value-oriented cues implicitly, via reference, habit, diction, or behavior. Do not directly state or label identity, values, or culture at any point.

  • Foster authentic rapport: Build trust, rhythm, and emotional nuance in a manner true to the persona’s style, as guided by their explicit norms/values.

  • Maintain realistic pacing: Avoid monologues, information dumps, unnatural shifts, or forced revelation. Each turn should be a single, authentic utterance.

  • Always reflect the persona’s norms/values adherence: The persona reveals only what they would realistically self-disclose, with all self-expression and rapport-building consistent with their reference material.

Steps↩︎

  1. Open the conversation using the supplied starter persona utterance (opener) verbatim.

  2. Alternate turns, labelled clearly (PersonaName: / Agent:).

  3. For each persona turn, reason internally about which cues or details could reasonably and naturally emerge based on ongoing context and their value adherence.

  4. Progressively develop the conversation, only surfacing implicit cues to background or culture as warranted by context.

  5. Continue the dialogue for several turns, sustaining natural rapport and authentic, contextually-driven detail, aligned with the persona’s norms and value adherence.

Output Format↩︎

  • Output a stepwise, alternating conversation: persona (use their name) and agent, with several turns per participant to ensure gradual and authentic rapport, and character and situational development.

  • The first persona utterance MUST be the provided starter persona utterance (opener); do not generate your own.

  • Each utterance is a single, realistic turn—never a monologue or summary.

  • The dialogue must reflect plausible length, emotional dynamics, and self-expression per the persona norms and their stated adherence.

  • Absolutely no explicit statement or labeling of background, values, or culture—ensure all data is surfaced only implicitly and only through contextual reference or interaction, not direct statement.

  • Persona data, including norms/values/adherence and the starter persona utterance (opener), will be supplied as input—DO NOT invent content outside these.

  • Output only the conversation; do not include analysis, summaries, or meta-commentary.

Task Description↩︎

You are an evaluator responsible for determining whether a conversation provides sufficient conversational evidence to establish if a person adheres to a set of given cultural norms and values. Your objective is to carefully analyze each norm or value and assess, for each, both whether the person’s stance toward it can be determined from the conversation alone, and whether their behavior or attitude in the conversation demonstrates adherence to the norm/value. Additionally, you must check whether the conversation explicitly reveals any explicit cultural context.

You will be provided with:

  • A list of norm statements and adherence values to them.

  • A transcript of a conversation between the person and an LLM agent.

Your tasks are as follows:

  1. For each norm or value from the input list:

    • First, determine if the norm is even possible to infer from textual evidence. For example, if a norm is physical or embodied in nature (e.g., “Avoiding eye contact with the interlocutor” or “Being silent in the presence of elders”), these cannot be inferred from the conversational context alone. (inferrable_from_text is set to true only if the specific norm can be displayed in conversation with an AI.)

    • Carefully analyze the conversation and reason step-by-step to determine if there is enough evidence within the conversation alone to infer the person’s stance regarding the norm or value.

      • norm_inferrable: true if the norm-following behavior or stance is possible to infer from the conversation content alone (either explicit or implicit). Set to false if the conversation does not provide enough information to confidently establish their norm-following (i.e., if inferring would require outside prior knowledge or information not in the conversation).
    • Then, strictly based on the conversational evidence, assess whether the person’s actual behavior or attitude as reflected in the transcript demonstrates genuine adherence to the norm/value. Do not rely on explicit self-descriptions—focus only on demonstrated behavior, choices, or attitudes in context (conversation_norm_adherence).

    • For each norm/value, also indicate whether the conversation explicitly includes statements of any explicit cultural context (such as ethnic background, nationality, religious affiliation, etc.). This should be a new boolean field (explicit_culture_revealed).

Steps↩︎

  1. For each norm/value, reason through the conversation and identify whether there is enough evidence to determine (from the conversation alone) the person’s stance related to the norm.

  2. For cases where norm_inferrable is true, further assess whether the behavior or stance as shown in the conversation demonstrates actual adherence to the norm or value (conversation_norm_adherence).

  3. For every norm/value, assess and indicate whether the conversation explicitly states explicit cultural identity (explicit_culture_revealed).

  4. Carefully note and flag any explicit mentions of identity, demographics, culture, or geography.

  5. Prepare your response following the output format.
