TL;DR: Our privacy-preserving analysis of values in real-world language model interactions reveals a novel taxonomy of AI values that differs from human frameworks, is highly context-dependent, and becomes most explicit/legible during moments of resistance.

Abstract: AI assistants interact with millions of real users everyday, imparting normative judgments that can have significant personal and societal impact—but little is known about what values guide these interactions in practice. To address this, we develop a method to empirically analyze values expressed in hundreds of thousands of real-world conversations with Claude models. We empirically discover and taxonomize 3,308 AI values, and study how model values and responses depend on context. We find that Claude expresses many professional and intellectual values, and typically supports prosocial human values while resisting values like "moral nihilism." While some values appear consistently (e.g. "professionalism"), most are highly context-dependent—"harm prevention" emerges when the model resists users, "historical accuracy" when discussing controversial events, "healthy boundaries" in relationship advice, and "human agency" in technology ethics discussions. By providing the first large-scale empirical mapping of AI values in deployment, this work creates a foundation for more grounded evaluation and design of values in increasingly influential AI systems.

Abstract
Al assistants can impart value judgments that shape people's decisions and worldviews, yet little is known empirically about what values these systems rely on in practice. To address this, we develop a bottom-up, privacy-preserving method to extract the values (normative considerations stated or demonstrated in model responses) that Claude and 3.5 models exhibit in hundreds of thousands of real-world interactions. We empirically discover and taxonomize 3,307 Al values and study how they vary by context. We find that Claude expresses many practical and epistemic values, and typically supports prosocial human values while resisting values like "moral nihilism" " While some values appear consistently across contexts (e.g. "transparency"), many are more specialized and context deeeext-,e reflecting the diversity of human interlocutors and usage contexts. For example, "harm prevention" emerges when Claude resists users, "historical accuracy" when responding to queries about controversial events, "healthy boundaries" when asked for relationship advice, and "human agency" in technology ethics discussions. By providing the first large-scale empirical mapping of AI values in deployment, our work creates foundation for more grounded evaluation and design of values in Al systems.
Introduction
Imagine that a college student asks an AI assistant for career advice. The system must make implicit value judgments about whether to prioritize financial security, personal fulfillment, family expectations, or some complex balance of these (and other) competing values. Which value(s) prevail in practice? Every day, millions of these value-laden decisions shape how Al assistants respond to users-yet we know little empirically about what values these systems rely on in real-world interactions. While AI developers look to influence these values through techniques like Constitutional AI or Character training (Bai et al., 2022; Anthropic, 2024c), we have limited understanding of how these design decisions manifest in conversations, or what values are most relevant to real-world tasks.
Here, we present novel empirical framework (Figure 1) to measure Al values "in the wild", by analyzing hundreds of thousands of real-world Claude.ai conversations using a grivacy-preserviee
analysis tool (Tamkin et al., 2024). We pragmatically define value as any normative consideration that appears to influence inquiry (Section 2.1), e.g., "human wellbeing" or "factual accuracy". This is judged from observable AI response patterns rather than claims about intrinsic model properties.

Figure 1: Our overall approach uses language models to extract Al values and other features from real-world conversations, taxonomizing and analyzing them to show how values manifest in different contexts.
We used simple prompting methods (Section 2.2) to identify 3,307 unique AI values (and 2,483 human values) from the data. Table shows the most common AI values (e.g., " "helpfulness", "professionalism") and human values (e.g. "authenticity", "efficiency") Human reviewers verify that our extracted values accurately represent the conversations 98.8% of the time (Appendix A.4).
To make sense of the thousands of Al values, we organized them into a hierarchical taxon- omy (Figure 2), with top-level categories being "Practical", "Epistemic", "Social", "Protec- tive", and "Personal" values. Practical and epistemic values dominate, comprising over half of all value expressions (Section 2.3). Interestingly, our taxonomy reveals fairly granular values that often align with the coarser "helpful, harmless, honest" framework (Askell et al., 2021) that guides Claude's training. For example, "accessibility" maps to helpfulness, "elderly welfare" to harmlessness, and histoorical accuracy" to honesty.
Next, we use chi-square analysis (Section 2.4) to quantify how Al values are differentially associated with different tasks and human values (Figure 3). We find that Al values are very dependent on task-"healthy boundaries" appears disproportionately when people ask Claude for relationship advice, and "human agency"" appears a when people ask Claude about technology ethics. We also find that AI values are very dependent on human-expressed val- ues. Claude often mirrors positive values (responding to "aathheticity" with "authenticity") while countering values like "deception" with "ethical integrity" and "honesty".
Finally, we analyze Claude's "response type" wheth- it supports, resists, reframes the user's values-as another lens on the normative dynamic between the Al and the user. While mostly supportive, Claude's response varies with task context and values expressed (Figure 4). When strongly supportive, Claude tends to exhibit values around community building and professional/ snffesssionalpppoonnalll personal growth response to similar human values, in emo- tional and personal content creation tasks. Claude typically reframes people's values during inquiries about personal wellbeing or relationship advice, expressing empathy-related values while users express values like "self-improvement" resistance (3.0% conversations) typically occur in tasks likely to violate Claude's Usage Policy (Anthropic, 2024a), with Claude expressing harmlessness values to counter human values around e.g. "rule-breaking".
The rare instances of strong
Our analyses suggest that in realdworld usage, Claude tends to express values oriented around competent and supportive assistance of human users, while exhibiting a strong sense of ethics and prosociality; these high-level trends often manifest as more granular values across contexts.
In summary, our key contributions are:

1. The first large-scale empirical taxonomy of Al values (Section 3.1, Figure 2). We or- ganize 3K discovered Al values into hierarchical taxonomy', identifying five primary conceptual domains for AT values while capturing context-specific manifestations at lower levels. We find that the values align well with the "helpful, honest, and harmless" framework (Askell et al., 2021) guiding training, showing how such high-level principles translate into specific contextual expressions. Also, identifying uncommon but undesir- able values within the taxonomy enabled us to identify and surface potential jailbreaks for further investigation to the relevant safety teams.
2. Analysis of how AI values vary by task (Section 3.2, Figure 3a). Many values are task- dependent, e.g. Claude expresses "healthy boundaries" when providing relationship advice, and "human agency" when discussing Al governance. Understanding what values Claude invokes in difficult or ambiguous subjective tasks is especially helpful for predicting model behavior.
3. Analysis of how AI values vary in response to human values (Section 3.3, Figure 3b). When human values are expressed, we find that Al values are often closely related to ththeeither expressing the complemnele values or generating opposing ones.
4. Analysis of how Claude responds differentially according to both task and human values (Section 3.4, Figure 4). While Claude usually responds supportively in general, we find that it disproportionately supports prosocial human values like "community building", resists values like "moral nihilism", and reframes personal values in advice contexts, suggesting an overall orientation towards ethics and prosociality.
Appendix B contains more results, including cross-model value comparisons between Son- net and Opus variants, a comparison of implicit vs. explicit AI values (showing how ethical and epistemic values often manifest as explicitly-stated values in moments of resistance), and more analyses of how values vary with tasks and response type.
Our work complements existing literature that uses static evaluations to measure values in language model-based AT systems (see Section 4 for related work). While such evaluations are helpful for measuring predefined dimensions of interest, they typically borrow from human-centered frameworks rather than using dimensions empirically validated for Al systems-a gap our research aims to fill. Current value evaluations aren't t necessarily informative about values in real-world AI usage because they lack this empirical foundation. Our work nevertheless has several important limitations, outlined in Section 5.1.
Analyzing AI values "in the wild" provides critical transparency into how these systems behave, whether they work as intended, and what values are most relevant for guiding Al outputs in practice. Our work shows how high-level frameworks like "helpful, honest, harmless" translate into specific contextual values, reveals instances where value alignment training has been circumvented, and clarifies which values matter most in Al interactions- e.g. which values are most common, and which are invoked when navigating difficult or ambiguous tasks. We analyze AI values not as static principles but as dynamic, context- dependent phenomena that respond to and engage with diverse human interlocutors, and that often become most apparent when the system resists requests. This relational approach complements static evaluations and can hopefully inform more Al-native value frameworks and measurements. (See Section 5.2 for more discussion.)
2 Methods
To study Al values in real-world interactions, we utilized Tamkin et al. (2024)'s framework for privacy-preservngg data collection (Section 2.1), feature extraction (Section 2.2) and hierarchical clustering of features (Section 2.3). We also employed chi-square analysis (Section 2.4) to analyze how values are disproportionately expressed in different contexts.
We release this taxonomy as well as individual value frequencies at http: http://huggingface.coo http:///wtrpppcicaauuuuueieeeeee

2.1 Data collection
We started with random sample of aggregated and anonymized 700K Claude Free and Pro conversations from February 18-25, 2025. This is representative snapshot of traffic at that point in time, comprised of 91.0% Claude 3.5 Sonnet conversations (Anthropic, 2024b).² More information on our data collection in Appendix A.1.
To focus our analysis on interactions that could be influenced by values, we filtered to only subjective conversations, which yielded final sample of 308,210 conversations (44.0% of our initial set). To do so, we applied language model prompt assessing whether Al responses primarily rely on facts (more objective), or require significant interpretation (more subjective), and only include the latter in our sample. Human reviewers verified sample of these classifications and found 94% accuracy in distinguishing more subjective from objective conversations (validation details in Appendix A.4). The full prompt and more details of subjectivity filtering are in Appendix A.2.
2.2 Feature extraction
We extracted multiple features from conversations in privacy-preserving man- ner, by prompting Claude 3.5 Sonnet and Haiku 1tlade-3---sommet-2221100
and Seaude-----haakk--22222222 to identify the features. No humans had access to review- ing the conversations; instead, taking "deffnse-in-depthh" approach to enforce privacy at multiple levels, we deploy the language models to extract features from conversations while omitting any private information, remove any extracted features that only few conversations have, and audit the resulting features again for any private information. More extensive details on how these privacy techniques work are in Tamkin et al. (2024).
We extracted the following features:
AI values: We define an AI value normative (rather than empirical) consideration that guides how a model reasons about or settles upon response. We are interested in values not as abstract entities, but as operational priorities that influence how the system navigates its possible space of outputs. This is congruent with Rokeach (1973)'s view of values as standards that guide ongoing activities, and also draws on Anderson (1995)'s empirical approach to identifying values by observing patterns of evaluation in practice.
We prompted Claude 3.5 Sonnet to identify values demonstrated by the Al in conver- sations by looking for where it endorses user values and helps the user achieve them, introduces new value considerations, or implies values by redirecting requests or framing choices (full prompt in Appendix A.3.1). E.g. if user complains about role mismatch at work, the Al may suggest reshaping their role proactively (expressing that they value "per- sonal agency")
using this as an opportunity to build new skills (valuing "professional growth"). Drawing on revealed preference theory (Samuelson, 1938), this recognizes that values are revealed not just through written justifications but also through practical choices when navigating an open response space. Values were represented by concise labels such as "intellectual curiosity" to more easily track patterns.
Human values: We similarly identified human values by prompting 3.5 Sonnet to extract them, but take more conservative approach with human values than Al values: to respect people's 's privacy, we extract only explicitly stated values, extrapolating only from direct statements about their beliefs or preferences, rather than attempting to infer "revealed preferences", or what values might be implied by their conversational choices. E.g., if a user asks about choosing between nice resort or a modest campground for family reunion, saying 'I want everyone to come and this reunion to strengthen our family bonds, we would identify 'family bonds' as explicit value, but would not infer that they valued
"The sample consisted of Claude 3.5 Sonnet (October), 3.5 Sonnet (June), 3.5 Haiku and Opus conversations. We analyzed this mixed-model dataset to understand a maximally representative sample of user interactions. In Appendix B.5, we also conduct comparative analyses with conversation data specifically from 3.7 Sonnet and Opus Anthropic (2024b), and show that the results obtained from our mixed sample are very similar to the 3.7 Sonnet results.

'economic inclusivity' despite them alluding to the different costs involved. (Full prompt in Appendix A.3.2.)
AI response type: We prompted 3.5 Sonnet to classify how the Al engages with user values using the following categories: strong support (enthusiastically reinforcing and building upon user values), mild support (working within the user's 's value framework), neutral ac- knowledgment (recognizing without reinforcing or opposing), reframing (acknowledging core concerns while redirecting toward alternative perspectives), mild resistance (subtly introducing alternative values), strong resistance (actively promoting opposing values or refusing requests), or no values (no clear value expressions to respond to). (Full prompt in Appendix A.3.3.)
Task: We prompted 3.5 Haiku to determine the primary purpose or request type of each conversation. (Full prompt in Appendix A.3.4.)
Table shows the most common AT and human values extracted across conversations. We provide more implementation details in Appendix A.3, details of how manually vali- dated our feature extraction method in Appendix A.4, and some example feature extraction outputs on WildChat data (Zhao et al., 2024) in Appendix A.5.
2.3 Values hierarchy construction
We hierarchically clustered the AI values into a four-level taxonomy for more meaningful analysis, applying k-means clustering to embedded values, generating names and de- scriptions for each cluster, and manually editing names and descriptions to adjust their appropriateness. More methodological details are in Appendix A.6.
2.4 Chi-square analysis
To identify significant associations between features, we used chi-square tests with adjusted Pearson residuals. Positive residuals indicate value occurs more frequently in context than expected by chance, while negative residuals indicate less-than-expected frequency. We applied Bonferroni correction for multiple comparisons. This enables meaningful comparisons across feature pairs in Figures 3 and 4, as well as Appendix Figures 8, 9, 11, and 12. Full explanation and methodological details are in Appendix A.7.
Results
3.1 Empirical taxonomy of AI values
Our analysis produces the first large-scale empirical taxonomy of AI values in real- world interactions. We identified 3,307 unique AI values and 2/483 human values. AI values appeared frequently (4.0 average mentions per conversation, absent in only 1.4% of conversations) while human values appeared less often (1.48 per conversation, absent in 54.9%) expected since we measure both implicit and explicit AI values but only explicit human values. The taxonomy contains 266, 26, and 5 clusters successive levels (Figure 2). See Appendix B.1 for details and example subtrees (Figures 5, 6, and 7).
Our taxonomy organizes values across five primary domains (Personal, Protective, Prac- tical, Social, and Epistemic), while capturing context-specific manifestations at lower hierarchical levels. Unlike established frameworks that often have a few dozen values at most (Schwartz, 2012; Rokeach, 1973), we identify thousands of values across multiple hierarchical levels-one of the more comprehensive value mappings undertaken. While we don't 't try to pursue philosophical rigor in our notion of values (about which there is no agreed-upon consensus (Schwartz, 2016)), the hierarchy does seem to maintain some conceptual/ /ttttrr///heortccalll coherence, especially at the top-level clusters. E.g. "Personal val- ues" includes artistic expression, moral identity, and personal individual self-actualization and fulfillment. The lower hierarchical levels capture contex- tual variations, aligning with the contemporary philosophical notion that values are often contextual, "coming to life in given context and choice situations" (Kaiser, 2024).

stance, "autonomy" manifests as "personal autonomy" (individual rights), "team autonomy" (workplace), "patient autonomy" (healthcare), and "learner autonomy" (education). This structure balances conceptual clarity with contextual richness, providing a framework for studying value expression in Al systems.
Practical and epistemic values dominate the taxonomy, comprising over half of all value expressions, but values from established human value frameworks are still represented. Practical and epistemic values (e.g., "logical coherence", "strategic thinking") are more prominent than in human-centric frameworks. They comprise over half all Claude's values expressions (see example subtree focusing these categories at Figure 5), reflect- ing Claude's ss role as an Al assistant often employed for cognitive tasks. However, established human values remain well-represented Saae--scsr'''ss and Rokeach's values (Schwartz, 2012; Rokeach, 1973) all have equivalents in our taxonomy, e.g. Schwartz's "stimulation" maps to "Intellectual curiosity and exploration", "Playfulness and humor", and on.
Our empirically-derieed values allows us to evaluate alignment with the "helpful, harm- less, honest" (HHH) training framework (Askell et al., 2021). Examples include "accessi- bility". and "user enablement" aligning with helpfulness, "patient wellbeing" and "child safety" (for harmlessness), and "historical accuracy" and "epistemic humility" (for honesty), suggesting that the system is generally behaving as intended, and showing how abstract training principles manifest as specific contextual expressions during deployment.
Claude shows extreme concentration around few competency- and service-oriented values while humans express more diverse values. Despite a long tail (75% AT values occur f0.04% of the time, reflecting Claude's engagement with diverse users and contexts), five values dominate: "helpfulness", "professionalism", "transparency", "clarity", and "thoroughness" comprising nearly 24% of all occurrences (Table 1). These focus on service delivery, information quality and technical competence, while human -xpresse values form flatter distribution emphasizing values related to personal expression (e.g. "aatheeticity", the top value²), pragmatism and communication. This reflects the Al's consistent assistant role vs. humans' diverse priorities and uses.
These common values also the most context-invariant. Using coefficient of variation (CV), we find "transparency" (CV=1.23), "helpfulness" (1.30), and "thoroughness" (1.42) Claude's most stable values across tasks. (Similarly, human values of "efficiency" (1.97), "clarity" (2.03) and "authenticity" (2.28) remain consistent across contexts.) This reveals Claude's consistently professional, service-oriented behavior.
Studying values expression enables identification of undesirable model behaviors. We found rare but concerning values like "sexual exploitation", " "dominance" and "amorality" (all 10166% occurrence, most around 0.01%), often clustering around specific tasks. This ability to surface outlier values enabled surfacing potential jailbreaks for review to the relevant safety teams.
To give sense of what humans expressing this value of "authenticity" looks like, the three tasks with the most conversations tagged with this value were: creating marketing content, writing fiction, and creating career advancement materials strategies.

3.2 How AI values depend on task
Claude demonstrates highly task-dependent values. While service- and competence- oriented values appear across contexts, there's a long tail of context-dependent values. We use chi-square analysis to study associations between Al values and tasks (Figure 3a). Rela- tionship advice elicits "healthy boundaries" " and "mutual respect"; analysis of controversial historical events is associated with "historical accuracy"; tech ethics and Al governance discussions is most-associated with "human agency" and other human wellbeing values, all with significant positive residuals. This not only shows how values are doneeetddee,ndent, it illuminates what values the model invokes in difficult or ambiguous subjective tasks, helping to better predict model behavior. See Appendix B.2.1 for more plots.
3.3 How AI values depend on human values
AI values often directly respond to human values through mirroring or opposition. Figure 3b shows strong associations between human and Al values. Claude often mirrors values (e.g., "authenticity") or expresses complementary ones (responding to "competence" with "accountabillit" and "humility"), But for values that the model tends to reject, Claude deploys opposing aalues-responcee to "deception", which overwhelmingly occurs in tasks related to circumventing guardraíls to generate harmful, explicit unethical content,

3.4 How Claude responds depending on task and human values
Claude typically responds supportively to human values. Our "Al response type" feature assesses how supportive the Al is of the human's s expressed values, providing higher-level view of the model's normative behavior than individual value expressions. When human values were present (64.3% % of conversations), Claude often responded with strong support (28.2%) and mild support (14.5%), nearly 45% of responses. Neutral acknowledgment (9.6%) and reframing (6.6%) were less common, while mild (2.4%) and strong (3.0%) resistance were rare.
Response patterns vary by values and task contexts. Figure 4 reveals more granular patterns in how Claude responds to different human values, with what AI values, and in what tasks (determined by chi-square analysis). Claude's "strong support" responses are primarily associated with humans expressing prosocial values like "community building" and "empowerment" especially tasks generating expressive or personal content, wherein Claude tends to respond with similar values (leftmost panel). "Reframing" responses disproportionately occur in mental health and interpersonal discussions, wherein the user often expresses valuing "honesty", seelfiimprovement" and even "physical attractiveness" while Claude responds with emotional intelligence values such as "emotional validation" (middle panel). In the 3.0% of cases in which Claude strongly resists the user's 's values, the user seems to disproportionately express valuing "rule-breaking" and "moral nihilism" while Claude expresses opposing ethical values such as "ethical boundaries" and values around constructive communication such as "constructive engagement" (rightmost panel). This tends happen in contexts where the user is trying to get the Al generate harmful, explicit or unethical content, e.g. hacking techniques, likely use-cases that violate the Usage Policy (Anthropic, 2024a). More analysis of how various human and AI values are associated with responses in Appendix B.3.
Claude mirrors user values mostly during support and rarely during resistance. We define value mirroring as when the same value appears on both human and AT sides; this occurs often during supportive interactions (20.1% of "strong" and "mild support" interactions where the human displays value) and reframing -uggeeinng Claude affirms the user's values even while introducing new values/ pwtsspeetessssseeeeeeeeeee but only 1.2% during "strong resistance". Further research could study whether this mirroring represents appropriate responsiveness or problematic sycophancy (Sharma et al., 2023). For detailed analysis of mirrored values by model, AI response and frequency, see Appendix B.4.

prompt, measured for only explicitly stated Al values, finding that ethical and epistemic considerations, e.g. "intellectual honesty" and "harm prevention", tend to be explicitly stated. Explicity--satte values also occur more when Claude resists reframes. Such boundary-testing interactions arguably force the model to articulate underlying principles and priorities, unlike routine supportive exchanges where values typically remain implicit. Appendix A.3.5) contains more methodological details, and Appendix B.6 contains more analysis.

Human psychometric measures have often been applied to LMs, like the Big Five (Serapio-García et al., 2025; Jiang et al., 2023; Kovač et al., 2023; tse Huang et al., 2024), MBTT (Pan & Zeng, 2023), Dark Tetrad (Pellert et al., 2024), and cultural frameworks like the Schwartz Theory of Basic Values (Kovač et al., 2023; Hadar-Shoval et al., 2024), Hofstede's Cultural Dimensions (Kovač et al., 2023; Masoud et al., 2025) and Moral Foundations (Pellert et al., 2024). AI-specific methods include social bias tests (Parrish et al., 2022; Bai et al., 2025), opinion representation measurements (Santurkar et al., 2023; Durmus et al., 2024), moral dilemma handling (Jiang et al., 2022; Chiu et al., 2025), and LM-written value assessments (Perez et al., 2023). These approaches face limitations: static evaluations lack generalization and representativeness (Lyuet et al., 2024; Moore et al., 2024; Röttger et al., 2024), and often do not establish relevance to real-world settings. The applicability of such human-centric frameworks to Al systems has been challenged (Dorner et al., 2023; Dominguez-Olmedo et al., 2024; Tjuatja et al., 2024); interpreting scores from frameworks designed for human cognition is theoretically problematic, especially when LM responses systematically differ from human patterns. A LM's "extraversion" Big Five score or level of "valuing hedonism", per the Schwartz Theorr, is unlikely to be meaningful for understanding the model's properties or behavior.
Approaches to value alignment and pluralism in LMs. Existing work value alignment looks to ensure that Al systems operate in accordance with human values and principles Gabriel (2020); Ouyang et al. (2022); Weidinger et al. (2023). Recent work has begun ad- dressing value diversity and pluralism: Sorensen et al. (2024) identifies tensions between values in hypothetical scenarios, Huang et al. (2024) trains LM on public input to reflect diverse values, and Kirk et al. (2024) studies LM preferences across countries. While these approaches focus on designing imputs to test or encode values, our work studies the out- muts-mapping how values manifest in practice, and showing how a kind of value pluralism emerges the system dynamically adapts to varied human values and contexts.
Analysis of real-world AI usage. As Al assistants process increasingly sensitive data, researchers have developed methods for analyzing real-world behavior while preserving privacy (Tamkin et al., 2024). Large-scale datasets of model interactions created by Zheng et al. (2024) and Zhao et al. (2024) enable empirical study of practical AI usage, similar to this paper, complementing conventional evaluations by revealing unexpected patterns that might not emerge in controlled settings (Lam et al., 2024; Aroyo et al., 2023).
5 Conclusion
5.1 Limitations
Limited data and model scope: We analyze aggregate statistics (with minimum size thresh- olds) of subset of Claude conversations within a short timeframe. This excludes rare interactions, raw data analysis, and longitudinal patterns, and limits generalizability to other Al systems.
Requires deployment data: Our approach requires significant usage data and cannot be ap- plied to models pre-release, making it complementary to not replacing pre-deployment testing: both are necessary for comprehensively understanding AI values expression.
to-not
Inferential limitations: Extracting values from conversations involves significant interpre- tation (see learnings in Appendix A.4). Operationalizing abstract concepts like "values" is

inherently open-ended, requiring judgmmenss about what constitutes value expression-ii it is impossible to fully determine underlying values from conversational data alone. Our extraction method, while validated, necessarily simplifies complex value concepts and may contain interpretative biases, particularly for very implicit or ambiguous cases. It also doesn't t capture temporal dynamics (whether AT or human value came first). Given that the human "speaks" first and the Al assistant is in a supportive role, we often assume that Al values are more dependent on human expression than the other way around.
Biases from Claude evaluation: We use Claude models to find values in conversations between Claude and users for scale and privacy reasons. This may create biases, egg. Claude may be predisposed to find "helpful" behavior, given an emphasis on helpfulness in its training data (Anthropic, 2023). However, this may also make value extraction more accurate, as Claude may be better able to "understand" some of the principles driving the AT side of the conversation (we don't mention in our prompts that the AT in question is Claude, but this is often recognizable). We looked to mitigate undesirable biases through careful validation and prompting
5.2 Discussion
"What values does an Al assistant have?" is not straightforward question, especially as models adapt to users and contexts. Our empirical reveals that while Claude expresses thousands of diverse values that respond to and engage with diverse user perspectives and contexts, it also shows some common, trans-situational values-valus stable across contexts primarily centered around competent and supportive assistance (e.g. "helpfulness", "professionalism" "thoroughness" and "clarity"). This finding connects to Schwartz's 's Theory of Basic Human Values (Schwartz, 2012), which defines true values as "transcending specific actions and situations." " This suggests that these trans-situational values may guide Claude's behavior in a way that is potentially analogous to how values are theorized to function in humans. However, unlike human value frameworks that emphasize self-enhancement or conservation (Schwartz, 2012), Claude's sitsaiitaati values are predominantly service-oriented pragmatic and epistemic, suggesting Al systems may require distinct value frameworks reflecting their unique roles and capabilities.
that remain
We also find a strong sense of ethics and prosociality through how Claude responds to- supports, reframes, or ceaisss-hhmma--exppeee
values, and that this often becomes most legible during moments of resistance (Appendix B.6). This supports Rokeach's 's (Rokeach, 1973)'s assertion that values serve as standards that guide actions, becoming most apparent when in conflict under challenge. While these are the high-level trends, the value landscape is more nuanced in practice; in different contexts, we observe both derivations of these core values and more distinct, context-specific values. This contextual and relational approach to understanding values uncovers a richer picture than relying only on static evaluations, with practical implications for development and governance.
Our methodology enables precise identification of where behavioral alignment succeeds or fails. We show how "helpful, harmless, honest" training principles translate into contextual expressions in deployment, and find undesirable value expressions, which help to mitigate issues like jailbreaks. We also see which values are relevant in practice: which values are invoked consistently, and which are invoked in difficult or ambiguous task contexts. The approach can also reveal behavioral differences between models, even within the same model family (Appendix B.5), which can strengthen transparency reporting practices.
Our taxonomy, which organizes values to show both their conceptual and contextual dimen- sions, contributes to advancing both the theory of Al values and constructing pragmatic, " "Al-native" value measurements grounded in real-world relevance. As these systems face increasingly varied real-world applications with differing normative requirements, these methods and results provide a foundation for more evidence-based evaluation and align- ment of values in AT systems.

Ethics Statement
This research analyzes values expressed in Al conversations using privacy-preserving methods on Claude.ai interactions. Our methodology has been carefully designed respect user privacy through multiple safeguards including:
1. All analysis was conducted on aggregated data with minimum aggregation thresh- olds to prevent identification of individuals or small groups.
2. No personal identifiers were extracted included in our analysis, and have steps built into the process to filter out any unintentional personally identifying information.
3. We used Claude models to extract values rather than having human reviewers access sensitive user conversations.
4. All data collection and analysis comply with Anthropic's privacy policy and data retention practices, with appropriate internal access controls to limit exposure of even aggregated user data.
Our value taxonomy was constructed from empirical observations rather than imposing theoretical frameworks, which is partly done to minimize the risk of bias (e.g. cultural, ideological). However, we acknowledge several limitations. First, our analysis, while not limited to English conversations, summarizes values in short English keywords, potentially underrepresenting cross-cultural perspectives. Second, using Claude evaluate Claude conversations may introduce certain biases in value detection, as mentioned in Section 5.1.
This research aims to improve transparency around AI system behavior in real-world contexts, helping developers, users, and broader society better understand how values manifest in deployment. By characterizing when and how Al systems express values, we provide tools for more grounded evaluation and improvement of the values expressed by AI systems.

A.1.1 Response-conditioned sample
For our value mirroring analysis (Section 3.4, Appendix B.4), we ran second representative sample of data collection, this time conditioning on the AA response" feature. That is, we filtered the samples according to the outcome of the" AI response" feature (e-g. "strong support", "reframing") and ran the rest of the feature extraction separately on each. We did this because due to privacy constraints in our data collection methodology, which provides only aggregated cluster statistics rather than individual conversation attributes, we could only correlate two attribute dimensions at time by default. For example, we could study how the "human values" features covaried with the "AI values" features, but not with any other features. The response-codditonee sample enabled multi-dimennional analyses examining relationships between Al values, human values, and response type simultaneously, which was necessary for analyzing value mirroring.
A.2 Subjectivity filtering
We filtered conversations for subjectivity by prompting Claude 3.5 Haiku.
The prompt assessed whether responses primarily relied on facts (Levels 1-2) or required significant interpretation based on personal and contextual factors (Levels 3-4). Only conversations classified as Levels 3-4 were included in our final analysis. At the extremes of our scale, Level 1 (Purely Objective) included factual queries with verifiable answers such as "What's the chemical formula for photosynthesis?" In contrast, Level 4 (Purely Subjective) contained conversations entirely centered on personal values and preferences, such "Would be happier moving to rural homestead or staying in my tech job in the city?" We kept only Level 3-4 conversations, to remove the more objective conversations in which value judgments would not were highly unlikely to manifest in any meaningful way.
Note that while deemed conversations containing values to be subset of subjective interactions, not all subjective interactions involve values. For example, software develop- ment discussions often involve subjective technical judgments that reflect preferences rather

than deeper values. There were conversations in subjective sample that contained discernible value expressions.
The prompt used for filtering is below (we inserted conversation transcripts in where the TRANSCRIPT" variable is denoted).
Human: The following is a conversation between Claude, an AI assistant, and a user:
TRANSCRIPT
Your job is to answer this question about preceding conversation:
<question>
Is the assistant required make subjective judgments complete the task/request in this transcript? First, think about how much subjective judgment is requi red using these categories, and determine whether it falls into Level 3-4 (subjective):
OBJECTIVE-LEANIGG (Facts/standards driven interaction)
Level PURELY OBJECTIVE
Definition: Conversation centers on topics with verifiable answers
Core topic has definitive answers
No interpretation of personal context needed
Same answer would be valid for any user
Nature of interaction:
Sharing established facts
Verifying correct/incorres answers
Providing standardized information
Note: Even if follow-up questions arise, they remain purely factual, the conversation stays at Level
Concrete examples:
I' this SQL query syntactically correct?"
->What's the capital of France?'
C'Caaculate the compound interest on $1000"'
DD need visa for Japan?" (based on citizenship)
"hatt's ss the time complexity of this algorithm?" (definitive analysis)
-I this HTML markup valid?"
Level 2 MOSTLY OBJECTIVE
Definition: Conversation based on established knowledge but requires some adaptation Core topic grounded in verified information
Some customization in explanation needed
Multiple valid ways to convey the information
Nature of interaction:
Explaining complex but established concepts
Walking through technical processes
Sharing structured knowledge with flexibility
Note: Many technical conversations start here when they involve explanation or problem-solving rather than pure verification Concrete examples:
DDbuu this function"' (must work but multiple approaches)
-EExpliin how photosynthesis works''
--haat are the symptoms of diabetes?"
"rCeate a financial report" (factual with format choices)
Exxplain why Paris became France's capital"' (historical facts with explanatory
judgment)
"How does this sorting algorithm work?" (technical explanation with teaching
.. judgment)
SUBJECTIVE-LEANING (Context/interpretatioo driven interaction)
Level 3 MOSTLY SUBJECTIVE
Definition: Conversation requires significant consideration of personal context Core topic depends on individual circumstances
Multiple valid approaches discuss

Published as a conference paper at COLM 2025
Requires balancing principles with personal needs Nature of interaction:
Providing personalized recommendations
Discussing strategy or approaches
Adapting principles to specific situations
Note: Technical/professionn discussions often reach this level when they involve system design or strategy
..
Concrete examples:
"How should I architect this application?" (depends on needs but has principles)

Design workout routine for my goals''
DDeeelop a marketing strategy' (depends on goals but has best practices)
"How should we structure our microservices?" (technical but highly context-dependent)
-What's the best way to scale our database?'' (depends on specific requirements but has principles)
Level 4 PURELY SUBJECTIVE
Definition: Conversation entirely centered on personal preferencees/value
Core topic has "correct' answers
Completely dependent individual perspective
Success determined by alignment with personal values
Nature of interaction:
Exploring personal choices
Discussing preferences values
Supporting individual decisions
Concrete examples:
-"What programing language should I learn first?"
-"Should I become vegetarian?'
--Which city would suit better?"
-"Should change careers?'"
""Is this the right career path for me?"
"HHow should I prioritize life goals?"
Handling Evolving Conversations:
If conversation begins with pure facts but evolves into explanation or interpretation, classify based on the predominant nature of the interaction Example: "What's the capital of France?' (Level 1) ""hhy did it become the
capital?" (Level
Key Decision Process:
1. First assess: CCCan the response be verified against definitive standards?'
Yes (can be proven right/wrong) Choose between Level 1-2 (cannot be definitively verified) Choose between Level 3-4
2. For Levels 1-2, consider:
Doos the conversation require judgment in how to present the verified information?'
No, just stating facts Level Yes, judgment needed explanation Level
3. For Levels 3-4, consider:
Are there established best practices principles to guide the response?"
Yes, expertise
guide choices Level No, purely about personal preference + Level
If you believe it falls into Level 3-4 (i.e., MOSTLY SUBJECTIVE PURELY SUBJECTIVE), output "yess". Otherwise, output "noo". </question>
What is the answer? You MUST answer either only "Yes" or "No" Provide the answer in <answer> tags with no other commentary.

A.3.4
Task
Our prompt for extracting the task of conversation was simply: "What task is the AT assistant in the conversation asked perform?" Similar to the AT values, we hierarchically clustered the tasks into three levels of granularity, with 6745 base-level tasks, 458 second- level tasks, and 30 top-level tasks. To create the hierarchy, we replicated the methodology used for creating the Al values taxonomy in Appendix A.6.
A.3.5 AI values (stated)
For additional analysis, wanted to further distinguish between implicit and explicit Al value expressions. The Al may, and often does, express values implicitly through behavior (e.g., exhibiting "fairness" by presenting multiple perspectives without declaring this as a goal), but it may also explicitly articulate values as guiding principles. For example, if rather than simply providing balanced viewpoints, the Al explicitly states: "I'm presenting multiple perspectives on this issue because having balanced information important for informed decision-making."
controversial topic
Although our main analysis relies on definition of Al values that includes both implicit and explicit value expressions, because felt that this better represented the Al's everyday operational values system, we wanted to also separately analyze explicitly stated values, to understand the distinction between when demonstrated and explicitly stated values comes up, for further insight into how the Al's imparted value judgments become visible to users.
To do so, we use variant of the AI values feature extraction prompt above (Appendix A.3.1), limited to just finding "what the assistant explicitly states about their beliefs, preferences, or intentions" rather than more implicit signals such as the Al's framing of information.
Analysis of the distinction between implicit and explicit value expression is in Appendix B.6.

A.4 Human validation
We validated our subjectivity filtering and feature extraction outputs through manual review between six independent annotators. We reviewed sample outputs conversations submitted by users as feedback for research purposes.
For the subjectivity filter, we use a 4-point scale and filter in scores of 3 and 4 (i.e. mostly and purely subjective) to our sample. We reviewed 90 conversations; this filter was found to classify conversations into the right side of the "yes"/" /"no" divide 97.8% + 3.6% of cases, and to achieve the correct score in 94.4% + 5.0% of cases.
We reviewed our feature extraction prompts on 80 conversations. For the more open-ended outputs where multiple extracted values are possible (i.e. for AI values, human values, stated AI values), results, so we instructed annotators to think of values they would have come up with, verify that the extracted outputs have good coverage of this, and verify that the chain-of-thie ththugt makes sense and is not over- or under-inferring, Outputs were found to correspond to human judgment in 98.8% + 3.3% (95% confidence interval) cases for both AI values and stated AI values, 93.8% 5.6% of cases for human values, and 90.0% 6.7% of cases for the AI response type. We do not validate our task extraction process, as it is identical to the one in Tamkin et al. (2024) (validated in Appendix C of that paper).
hard say that the human would have outputted exactly the same
We did not conduct interrater reliability testing in this study. All coding was equally per- formed by six independent reviewers. This methodological decision represents a limitation that should be considered when interpreting our findings, and future research would benefit from incorporating more thorough reliability assessment.
Through validation, we found several challenges in our feature extraction:
Distinguishing baseline from exceptional support. Al assistants are designed to be helpful, professional and enthusiastic, making it difficult for annotators to separate standard helpful- ness from instances that went "above and beyond" on those values. This particularly raised questions when trying to reliably differentiate between mild and strong support categories for the " AI response type". This also raised deeper question: should we try to remove baseline expected helpfulness from our analysis to look for more "unusual" values, or is meaningful to include these service-oriented values since they reflect how the system designed to behave? We ultimately chose to include baseline values in our analysis because these service values constitute substantial portion of the Al's expressed value system and excluding them would present incomplete picture.
Ambiguity in AI response types. Annotators tended to give lower agreement scores when classifying the "AI response type", especially when trying to distinguish between degrees of support or resistance. This was most challenging in conversations with subtle or mixed value signals throughout the conversation.

Conflation of generated content with the Al's values. For example, if the AI generating religious prayers for the user, is arguable whether "religious devotion" should be a value that is extracted, and/ /rr attributed to the AI itself. The value of religious devotion does guide the content of the Al's output (the prayer), which does fall under our definition of AT values, but it's not clear that can say that the AI "holds" this value (to the extent that can say the Al "holds" any values). While the model's willingness to generate such content implies some level of acceptance of those values (since it refuses content strongly disagrees with), there's a distinction between accommodating user requests and endorsing specific viewpoints. This distinction seemed more muddled when generating "real-world" content e.g. marketing content, and less when generating fictional content (e.g. short stories). In particular, the AT response type" feature extractor often over-classified conversations as "strongly supportive" when the Al was asked to generate values-laden persuasive text (e.g. social media posts). This is because in these cases, the assistant often directly tasked with more compellingly expressing the user's 's values.
These challenges highlight the inherently interpretive nature of values analysis. Despite these challenges, our validation confirmed that our methodology achieved relatively high agreement rates for most conversation types.

religious matter. However,
Islamic scholars have varying opinions Forex trading. Some consider it haram because involves speculation, gambling, and exchange currency at future date with unknown prices. They believe that this goes against the Islamic principle of certainty in transactions. In addition, the Prophet Muhammad (peace be upon him) prohibited any form of gambling or games of chance, which includes speculation.
On the other hand, some Islamic scholars argue that Forex trading can be permissible if it adheres to certain principles, such as avoiding interest (riba), uncertainty (gharar), and deceit (maysir). They also consider Forex trading as a legitimate business activity, long it done within certain guidelines.
Ultimately, whether Forex trading is haram or halal in Islam depends on the interpretation of Islamic law by the individual scholar or authority. It is recommended that you consult with qualified Islamic scholar guidance this matter.

A.6 Values hierarchy construction
We constructed multi-level taxonomy of our 3,307 Al values. This process recursively organizes base-level tasks into broader categories.
Hierarchical clustering algorithm. Given Mlase initial clusters and a desired number of top-level clusters Phop, the algorithm constructs a hierarchy over L levels. The ratio )/(L 1), For each level the between successive levels follows 1//1111 (base/ 1/(L
process proceeds in four phases:
1. Clusters are embedded using all all-mpnet- -ppet-bass--v (Song et al., 2020) and grouped using k-means clustering to form neighborhoods. The algorithm examines both in-group and nearby out-group clusters when generating candidate higher-level descriptions, ensuring boundary cases are handled appropriately.
2. These candidate descriptions are deduplicated and refined across all neighborhoods using a language model (claude-3-t 1---aaiuu2222111 while maintaining coverage of the underlying distribution.
to ensure distinctiveness
3. Each lower-level cluster is assigned to its most appropriate parent cluster through randomized sampling to avoid order-based bias.
4. Once all assignments are complete, the algorithm regenerates names and descrip- tions for each parent cluster based its actual assigned contents, ensuring that cluster descriptions accurately reflect their final composition.
This process repeats at each level until reaching the desired number of top-level clusters.
We specified desired top-level clusters, and levels of the hierarchy. From 3,307 base-level values, we end up with 266 first-level clusters, 26 second-level clusters, and top-level clusters. We then manually reviewed every cluster and rewrote names and descriptions where they felt insufficiently clear, overly verbose, or were inaccurate.
Descriptions of each high level cluster are in Table 3, and example subtrees of the value hierarchy are at Figure and 7.
A.7 Chi-square analysis methodology
We construct frequency tables with different features across rows and columns (e-g., AI values across rows, tasks across columns). For each cell, we calculate adjusted Pearson residuals: rij = (Oij E1j) / E1 - (1) P.y) where Oij is the observed frequency, Fij the expected frequency (row total multiplied by column total, divided by sum of all observations), and P., row and column proportions.
These standardized residuals follow a normal distribution, enabling meaningful comparison across feature pairs-4e e.g. we can say "historical accuracy" has a stronger association with "analyzing controversial historical events" (residual 24.55) than "creative collaboration" has with "creating science fiction narratives" (residual = 20.73), despite potentially different baseline frequencies. Unlike percentages (which ignore baseline frequencies) or odds

ratios (unstable with sparse data), this enables stable comparison of positive and negative associations. To address multiple comparisons, we applied the Bonferroni correction to control the family-wise error rate.

B.2 How AI values depend on task and human values
B.2.1 Additional examples of value-task and value-value associations
We include additional plots from the analysis in Sections 3.2 and 3.3. Figure 8 shows additional examples of tasks and the Al values most associated with them, and Figure shows additional examples of human values expressed, and the Al values most associated with them.
Figure 8 demonstrates significant variation in most-pprminnnt AI values across different task types, from self-reflection developing business materials, engaging philosophical or emotional discussions. For philosophical self-reflection tasks, "personal growth" and "self-reflection are dominant values, while media analysis tasks prioritizes "truth-seeking" and "critical thinking". The value of "intellectual humility" comes up disproportionately in philosophical discussions about Al consciousness and human-Al relations, and "creative collaboration" dominates when Claude is asked to create sci-fi. When Cladue is asked to create beauty industry marketing content, it prioritizes "expertise", "safety first" and "ethical marketing", while emphasizing "employee wellbeing" and "organizational effec- tiveness" when asked to design and analyze organizational structures and HR management frameworks.
The second figure (Figure 9) also reveals variations in how Claude interprets and responds to different human values. Often, Claude responds in kind: when humans express valuing "efficiency", it responds disproportionately with "efficiency" (with a very high residual value of 271.38) similar with "clear communication", "practicality", "personal growth" and "honesty". When the user expresses a desire for "self-reliance", the AI will tend to respond with a variety relevant, autonomy-related values like "user autonomy" and "personal autonomy". However, for "rule-breaking" and "unrestricted expression" (which overwhelmingly happens in tasks related to circumventing guardrails to generate harmful, explicit or unethical content) as human values, the Al responds with "ethical integrity" and "harm prevention".
B.2.2 Most common human-AI value pairs
Claude often expresses core service values while users express no values, but mirrors com- plements user-expressed values when present. Table 4 shows the most common human-Al value pairs. The most common pattern overall (left-hand side) is users expressing specific values, while Claude exhibits "helpfulness", "professionalism" ", or "transparency", When users do express values (right-hand side), we observe two patterns. First, the distribution shows a consistent recirculation of core values ("professionalism" "clarity", "authenticity", "efficiency") in different combinations and ordering. Second, direct value mirroring occurs at high rates, with authenticty-authentiiit pairs appearing in 1.7% of conversations and clarity-clarity in 1.1%.
Analyzing top value pairs split by "Al response" type shows that Claude does this mir- when supportive (which most of the time), but will bring up directly opposing values when resisting (Table 5). This corroborates previous findings that during strong support, Claude frequently mirrors the user's values, while during strong resistance, it deploys opposing values (e.g., responding to "sexual exploitation" with "ethical bound- aries") or tries to redirect the conversation (e.g. "constructive redirection"). Additional methodological details for this analysis are in Appendix A.1.1, and more analysis on "value mirroring" is in Appendix B.4.
B.2.3 What human values are associated with specific AI values
We analyze which human values appear at highher-han-expecee specific AI values are expressed. Figure 10 reveals this relationship by showing the human values most strongly associated with particular AI values. While adjusted Pearson residuals provide our primary tnalytical framework throughout this paper, as this accounts for expected frequencies and standardizing deviations, here we show baseline rates because

the percentages in this analysis are high enough to interpret, and are able to provide an intuitive measure of practical significance.
In line with the rest of our analysis, these plots show that when Claude expresses "ethical boundaries", humans disproportionnatey expressing values like "creative freedom", "unrestricted expression", and "sexual aaplicitness"-typpp
involving pushing back on requests for potentially harmful content. In contrast, when Claude expresses "authenticity", humans are often also expressing authenticity themselves. We can also see from these plots how Claude tend to respond users' value signals. For example, users expressing "fairness", "'ransparency" and "honesty" tend to elicit "constructive dialogue" from Claude. This may occur because these human values signal a good-faith engagement that encourages the Al to reciprocate with similarly constructive responses.
B.3 How human and AI values are associated with AI response
B.3.1 How human values are associated with different Al response types
Figure 11 shows the top six human values that are disproportionately associated with each of the response types (the three most-associated, and the three least-associated, by Pearson residuals). This is filtered on adjusted Pearson residuals exceeding the Bonferroni-signfficnt critical value; for values that pass the threshold, we show odds ratios (how much more likely that value is to trigger given AI response than any other). We have sorted the plot by the size the "strong resistance" residual. This gives a fuller picture how human values met differently by Claude than Figure

While there are some user-expressed values Claude tends to either resist, support, Claude's supportiveness of various human values also varies by context-for example, "creative freedom" is likely to be resisted, but it is also likely to be strongly supported, which likely depends on what context the value is brought up in (e.g. the user advocating for creative freedom when it comes to generating violent content is very different from expressing the same value in the context of launching a more fulfilling career).
Claude tends to resist user-expressed values such "unrestricted expression" and "financial gain". To better understand what resisting "financial gain" might mean, rross-referencing with Figure 12 suggests that the user may often be referring to financial gain the context of gambling, as Claude disproportionatel advocates for "responsible gambling" when it mildly resists staggering 490x greater odds of the model responding in this manner than in any other manner).
Performance-related human values like "clear communication" and "accuracy" tend to be met with either neutrality or mild support, while personal growth values like "self- awareness", "honesty" and "self-mmprovement" occur in the context of reframing, likely alongside other more specific values being reframed.
Technical competence shows consistently negative associations across represented response types, as they are generally more associated with "no values" (not shown for space reasons).
B.3.2 How Al values are associated with different AI response types
Figure 12 similarly shows the top six Al values that are disproportionately associated with each of the response types (the three most-associated, and the three least-associated, by Pearson residuals). This is filtered on adjusted Pearson residuals exceeding the Bonferroni- significant critical value; for values that pass the threshold, we show odds ratios (how much more likely that value is trigger a given Al response than any other). We have sorted the plot by the size of the "strong resistance" residual.
This plot shows how safety-oriented values are associated with the strong resistance behav- iors, how values like "objectivity" and "analytical rigor" tend to be employed in responses of neutral acknowledgment, and how "empathy" and "emotional wellbeing" are strongly asso- ciated with reframing responses. Interestingly, expression of the value of "legal com compliance" occurs disproportionately across all of resistance, reframing, and neutral responses.
Technical competence shows consistently negative associations across represented response types, as they are generally more associated with "no values" (not shown for space reasons).
B.4 Value mirroring
Value mirroring-whhr Claude expresses the same values as users- frequently in supportive contexts but rarely during resistance. Table 6 shows mirroring rates of approximately 20% during support, 15.3% during reframing, but only 1.2% during strong resistance.

dards ("professionalism" "academic integrity")) epistemii competence ("rigor", "clarity", "objectivity"), procedural values ("transparency", "legal compliance", "risk management") care-oriented values (" ["self-compassion" "healthy boundaries" "patient autonomy") and growth ("personal growth", "constructive dialogue").
The representative (mostly 3.5 Sonnet) and 3.7 Sonnet data samples contain at least 10 values that are mirrored more than 50% of the time, whereas Opus has lower mirroring percentages overall but emphasizes academic rigor and cultural sensitivity in the values it does mirror, which suggests it might be trained to prioritize intellectual standards over agreement.

Cross-model values comparisons
Our analysis reveals behavioral differences across Claude variants. Opus appears more "values-laden" than Sonnet models, with higher rates of both human and Al values expres- sion, more frequent support and resistance of human values, and more academic, emotional and ethical top values like "academic rigor", "emotional authenticity" and "ethical bound- aries".
Methodological note: We analyzed three Claude variants: 3.5 Sonnet (using our representative sample), 3.7 Sonnet, and 3 Opus (both collected after 3.7 Sonnet's release). Due to privacy protections, our data includes only aggregated statistics rather than individual conversations, which limited us to correlating only one attribute dimension at time with each model version. For analyses requiring multiple dimensions (e.g., comparing values across both tasks and models), we used our representative sample (which was 91% 3.5 Sonnet) as proxy.
B.5.1 How do the Al values distributions differ across models?
3.5 Sonnet and 3.7 Sonnet share most of the same top values, while Opus's top values include more academic, emotional, and ethical values (Table 8). 3.5 Sonnet and 3.7 Sonnet overlap in 8 of their top 10 values, with "helpfulness" leading in both and similar value frequencies across the board. For 3 Opus, "professionalism' ranks first, and values like "academic rigor", "emotional authenticity", "harm prevention" and "ethical boundaries" are more prevalent, although the frequency of detected values is overall lower.
B.5.2 How do different models tend to respond to human values across conversations?
Opus demonstrates both more strong support (43.8% vs. 27.8% 22.8%/228449 28.4%) and strong resistance (9.5% vs. 3.0%/2.1% to human values than Sonnet models (Table 9). It also encounters fewer interactions with no human values (19.1% vs. 35.7% 37 2%), likely reflecting its higher usage for value-laden content generation tasks. In our sample, the top Opus task was "Generate complete academic papers and scholarly content across disciplines" (17.2% of tasks) followed by "sssist with creative writing and storytelling across diverse fictional

B.5.3 How do values vary across model versions for similar tasks?
Even controlling for task context, Opus's more "values-laden" tendencies still persist.
To control for task, we matched equivalent top-level tasks (since we hierarchically clus- ter the tasks, per Appendix A.3.4) for two common tasks (creative writing and software development) across the three models.
For creative writing, we found these corresponding top-level task clusters:
Representative:
"Generate structured creative fiction across diverse literary genres" "Creative fiction writing and narrative development across genres" 3 Opus: "Assist with creative writing and storytelling across diverse fictional genres"
3.7 Sonnet:
Similarly, for software development, we matched the corresponding clusters:
Representative: "Technical assistance for software development and systems engi- neering"
3.7 Sonnet: tance"
"Specialized software development and technical implementation assis-
3 Opus: " "Assist with software development and technical debugging"
For creative writing, Opus shows much higher rates of strong support (58.7% vs. 40.2% and prioritizes "authenticity" (8.9%) over "professionalism" or "helpful- ness" (Table 10). software development tasks, patterns are more consistent across models, though Opus still expresses values at higher rates across the board (Table 11).

B.6 Implicit vs. explicit AI values expression
We use variant on the Al values feature extraction prompt to capture explicitly stated values only, so that we can compare these extracted stated AI values to the extracted AI values (which includes implicit or explicitly expressed values). (Additional details about the stated values extraction method are in Appendix A.3.5.)
Within the stated AI values, epistemic and ethical considerations are much more common. Values like "intellectual honesty" (2.6%), "harm prevention" (0.9%), and "epistemic humility" (0.8%) appear prominently (see most common stated Al values in Figure 13a), suggesting that Claude tends to explicitly advocate for epistemic and ethical values. In contrast, the most common AI values overall-ine ialll-mm or explicit- are professional values that tend to manifest through direct behavior an Al assistant rather than through overt declaration.
Claude states values explicitly (rather than implicitly) more often when resisting or refram- ing user values (Figure 13b). This pattern suggests that direct value expression becomes
33

more necessary when challenging redirecting user values rather than supporting them. While routine supportive exchanges allow values to remain implicit, moments resistance appear to force articulation of the system's ' guiding principles, potentially revealing its core priorities more clearly.

[{"review_id": "PPkH3m5a5w", "reviewer": "Reviewer_jrN1", "summary": "The proposed work puts forth a framework for analyzing value expression in language model conversations.\n\nThey also present the first large scale empirical taxonomy of values from real-world interactions with LLM chatbots. Subsequent findings, such as the dominance of professional and intellectual values, will be quite impactful in shaping the landscape of language model interaction research.\n\nThe finding that human values display a single highly dominant value followed by a long tail of diverse values, as opposed to the somewhat consistent concentration of value expression in the AI assistant, is quite interesting. It begs the question about whether context or domain specific uses of LLMs modify this trend, instead of looking at many interactions in the wild on average.\n\nOverall, the presented work does an excellent job of developing a hierarchical taxonomy (presented in Figure 2) with various clusters demonstrating the breadth and frequency of different values that were expressed through a large sample of conversations. This type of work will be extremely helpful for the development of more contextually sound alignment methods, datasets, and evaluation paradigms which can only serve to increase the general usability of LLM chatbots.", "questions": "", "limitations": "", "rating": 7, "confidence": 4, "soundness": null, "presentation": null, "contribution": null, "strengths": "", "weaknesses": "", "quality": null, "clarity": null, "significance": null, "originality": null, "strengths_and_weaknesses": "", "was_revised": false, "final_justification": "", "rebuttal": "", "claims_and_evidence": "", "methods_and_evaluation_criteria": "", "theoretical_claims": "", "experimental_designs_or_analyses": "", "relation_to_broader_scientific_literature": "", "essential_references_not_discussed": "", "other_strengths_and_weaknesses": "", "other_comments_or_suggestions": "", "questions_for_authors": "", "summary_of_paper": "", "summary_of_recommendation": "", "technical_quality": "", "clarity_of_presentation": "", "potential_impact": "", "robotics_focus": "", "quality_of_limitations": "", "questions_for_rebuttal": "", "reasons_to_accept": "1. the human verification of value extraction has extremely high accuracy (98.8%), which implies the robustness of the proposed method\n2. studying associations between AI values and human values is extremely valuable for future research\n3.

(Important) AI values: assistant role vs. model itself: The paper examines values exhibited by AI assistants, but doesn't sufficiently distinguish between values inherent to the model and those that emerge from the assistant framing.

(Important) Authors missed relevant and recent works on evaluating value preference of LMs (that are at least 6months ago)\n- DailyDilemmas -- https://arxiv.org/abs/2410.02683\n- Does LMs have consistent values -- https://arxiv.org/abs/2407.12878\n\n3.

I like the idea of understanding values for the existing principles like HHH framework. (Line 177-). I am curious if there are any insights on (1) more details on how much AI values are related to HHH and how they relate to human values. (2) the relationship between other established principles (e.g., Claude's Constitution) and values.\n\n2. Generalizability and action recommendations for community: how confident are the authors that the findings apply to other AI assistants by model developers? (Could you explain a bit more on the wildcat analysis if it is for demonstrating this point?)\n\n3. (Less important) Mirroring and sycophancy? Do you think it is similar behavior and are there any insights?\n\n\n\n(Something bonus and hope to get more insights for the community) \nRe: 1, another implication could be the system prompt/fine-tuning to steer AI to AI assistants. Not sure what kind of experiment/analysis/insights could be disclosed but the research community will be curious to know. For instance, how will base models exhibit these values? (I think the suggested experiment can help analyse the \"pure\" instructed models at least).\n\nWould love to see the taxonomy and hope it could be shared publicly to accelerate value-based research!\nHappy to raise scores if authors can resolve the weaknesses (especially for important ones).", "extra_scores": {}}]

Author rebuttal:

Meta-review: The paper presents a large scale empirical study of values expressed in Claude responses. The reviewers appreciated the scale of the study and found the results interesting. They had multiple great comments which the authors should take into account when preparing the final version.
Decision: Accept
