Summary

This study evaluates the measurement validity of using Large Language Models (LLMs) as proxies for human cultural values via the Inglehart-Welzel Cultural Map. The authors decompose response variance into stochastic noise, prompt framing sensitivity, and cultural signal. Using a Noise-to-Signal Ratio (NSR), they find that for 42% of model-question pairs, noise exceeds the cultural signal, rendering cultural attribution unreliable. While LLMs generally cluster toward Western, English-speaking cultural positions, prompt tone alone can shift model coordinates by up to 2.4 units, comparable to inter-country distances. The study highlights that current LLM outputs lack the precision required for valid cultural representation without rigorous reliability testing.

Abstract

Abstract:Researchers increasingly treat LLM survey responses as a proxy for human cultural values. This includes projecting model outputs onto instruments like the Inglehart-Welzel Cultural Map and drawing conclusions about which cultures a model resembles. While a model's answer to a value-laden questions may be interpreted as a cultural signal, it also carries sampling noise and, can be quite sensitive to question framing. In this paper, we separate survey responses, sampling noise and question framing for multiple LLMs. We decompose response variance from these models into variation across random seeds, prompt rewordings. We employ noise-to-signal ratio (NSR) to test whether a model's apparent cultural position is distinguishable from noise. When applied across a dozen models from four geographic origins, calibrated against 88 Integrated Values Survey countries, the answer is often no. NSR exceeds 1.0 on 49 of 117 valid model-question pairs (42%), reaching 5.56 in the worst case. Two models even refuse to answer sufficient number of survey questions outright. Our results corroborate previous findings that LLMs cluster toward Western, English-speaking cultural positions. However, what does not hold up in this study is the precision with which anyone can currently interpret a specific model's coordinates: prompt tone alone can shift a model by 2.4 map units, comparable to the distance between actual countries in the Inglehart-Welzel Cultural Map. These findings suggest that cultural attribution from LLM survey responses requires establishing the reliability of the underlying measurements before interpreting model coordinates as evidence of cultural representation.

These findings suggest that cultural attribution from LLM survey responses requires establishing the reliability of the underlying measurements before interpreting model coordinates as evidence of cultural representation. 1 Introduction Large language models are increasingly used not just to generate text but also to simulate human cognition. This includes cultural values, political beliefs, and social norms. A growing body of empirical work treats model outputs from survey instruments as proxies for human opinions Argyle et al. (2022); Cao et al. (2023); Arora et al. (2022); Venkatakrishnan et al. (2026), and studies have begun drawing substantive conclusions about which cultures LLMs are closest to and whether certain model families exhibit geographic bias Tao et al. (2024); Atari et al. (2023). This use of LLMs as measurement instruments has a number of important consequences: it influences how researchers interpret model behavior, how developers audit for cultural fairness, and how policymakers assess risk of cultural homogenization. However, using LLMs as survey instruments requires demonstrating that LLMs actually measure what they claim to measure. Studies of these claims are relatively scarce. In this paper, we demonstrate that when a model produces a response to a value survey question, that response is shaped by at least three distinct forces: stochastic sampling noise (variation across random seeds), sensitivity to prompt wording (variation across semantically equivalent framings), and whatever latent cultural signal the model genuinely encodes. Prior work has treated observed variation as reflecting the third, without ruling out the first two. We frame this as the measurement validity problem, and apply it concretely to the Inglehart-Welzel Cultural Map framework Inglehart and Welzel (2005). This is the same framework used by Tao et al. Tao et al. (2024) in their widely cited PNAS Nexus study on LLM cultural bias. The cultural map projects responses to a set of value-survey questions onto a two-dimensional space via PCA, separating populations along axes of Survival vs. Self-Expression and Traditional vs. Secular-Rational values. Tao et al. projected five GPT-series models onto a map calibrated against 107 countries from the Integrated Values Survey (IVS). The IVS is a merger of the World Values Survey and the European Values Study. They found consistent clustering near English-speaking and Protestant European countries. They attributed this to the composition of the training data and called for replication using open-weight models and more systematic prompt-sensitivity analysis. We address both by expanding the model set and systematically measuring prompt sensitivity. In addition to replicating parts of Tao et al. (2024), we expand their work in three ways.11 1 We plan to release all data and code publicly. First, we expand the model set from five Western proprietary models to twelve models spanning four institutional origins: US-based (GPT-4o, GPT-4o-mini, Claude Sonnet 4.6, Gemma2-2B, Phi3-Mini, Llama3.1-8B), European (Mistral-7B), Chinese (Qwen2.5 at three scales, Yi-6B), and Saudi–Chinese (AceGPT-7B); Table 1 groups these instead by target-deployment region (Western, East Asian, MENA). Second, we decompose response variance into three components: stochastic noise (σseed _seed) across random seeds, prompt-wording sensitivity (σprompt _prompt) across tone-and-persona variants, and cultural signal (σculture _culture) across models. Third, we combine these into a per-pair noise-to-signal ratio, NSR(m,q)=(σseed+σprompt)/σcultureNSR(m,q)=( _seed+ _prompt)/ _culture, and use it as a validity criterion: when it exceeds 1.0, instrument noise swamps the between-model spread that any cultural interpretation depends on. Our main results are as follows: Western bias replicates robustly. Every model that produces a projectable coordinate lands in the self-expressive half of the cultural map under neutral prompting, with GPT-4o at (3.66,0.18)(3.66,0.18), close to the PNAS reference (3.35,0.50)(3.35,0.50). We note that measurement validity fails substantially, as detailed in Section 4. Frontier scale does not guarantee reliability: GPT-4o exceeds the validity threshold on 6 of 10 items. Alongside noisy responses, we also document categorical refusal: Llama3.1-8B declines F118 (Justifiability of Homosexuality) and F120 (Justifiability of Abortion) across all prompts, and AceGPT-7B declines G006 (and, at some tones, additional items), rendering both models unprojectable onto the cultural map. Prompt tone alone shifts individual model positions by up to 2.4 map units, comparable in magnitude to between-country distances in the IVS ground truth. Based on these results, this paper makes three contributions. Conceptually, we show that cultural attribution in LLMs cannot be taken at face value i.e., before any claim about a model’s cultural position is substantively meaningful, it must first clear a measurement-validity bar. We also observe that for a large share of model-question pairs under consideration it does not. Methodologically, we introduce three-component noise decomposition and the accompanying noise-to-signal ratio as general-purpose diagnostic instruments for this study. We note that this is applicable to any survey-based LLM evaluation and not specific to the Inglehart-Welzel framework. Empirically, we provide the most geographically diverse replication of the Inglehart-Welzel framework to date, spanning twelve models across four institutional origins, and we show that the resulting cultural attribution is at least as much a property of the survey instrument as it is of training-data composition. Taken together, these contributions reframe cultural attribution in LLMs as a measurement-validity problem. 2 Related Work A central question in recent NLP research is whether LLMs encode cultural values and, if so, whose. Argyle et al. (2022) introduced the concept of silicon sampling, demonstrating that GPT-3 can be conditioned via demographic prompts to replicate distributions from the American National Election Survey. Abdurahman et al. (2024) take a more cautionary stance, documenting that LLMs used as psychological proxies show suppressed variance and fail to reproduce the nomological networks observed in human samples. The work raised doubts about whether outputs that look like value profiles are genuine value representations at all. Cao et al. (2023) and Arora et al. (2022) additionally documented that Western cultural values dominate across a range of frontier models, with non-Western perspectives systematically underrepresented. This pattern has also been documented for Arabic specifically: Naous et al. (2024) show that Arabic and Arabic-monolingual models default to Western cultural framing even when prompted in Arabic, using entity-substitution rather than survey methodology. This concern is also echoed by Bisbee et al. (2024), who show that LLM-generated survey responses can match human population averages while still being unreliable for statistical inference. Atari et al. (2023) observed that LLM responses on psychological measures are outliers relative to cross-cultural data and most resemble those of Western, Educated, Industrialized, Rich, and Democratic (WEIRD) populations. While these findings motivate the use of LLMs as low-cost instruments for cross-cultural research, none formally examine whether such instruments are sufficiently reliable for this purpose. This pattern is consistent with earlier findings that LLM-generated opinions disproportionately reflect the views of left-leaning, educated, and wealthy populations Santurkar et al. (2023), and that measured representational gaps persist even when models are explicitly prompted to represent specific countries Durmus et al. (2023). The most direct predecessor to this work is Tao et al. (2024), who positioned five GPT-series models on a cultural map calibrated against 107 countries from the Integrated Values Survey by querying the models with 10 value-survey items and projecting their responses through the same PCA pipeline applied to country data. As discussed above, they attributed this clustering to training-data composition and called for replication on open-weight models with more systematic prompt-sensitivity analysis; our work addresses both directly, extending to 12 models spanning 4 geographic origins and introducing a three-component noise decomposition that quantifies, rather than illustrates, instrument sensitivity. Beyond systematic bias, a separate concern is that LLM outputs for value and opinion questions are unstable under surface-level prompt variations. It is important to note that prompt-format sensitivity is a documented general property of LLMs, not unique to value or opinion questions Sclar et al. (2024). A parallel line of work shows that stochastic randomness alone, independent of prompt wording, produces nontrivial variation in model behavior across otherwise identical runs Sellam et al. (2021). Most relevant to our work is Khan et al. (2025), who tested five frontier LLMs on cultural-alignment instruments and identified failures along three axes: stability, extrapolability, and steerability. Khan et al. (2025) establish that current cultural-alignment evaluations are unreliable, but treat instability as a single phenomenon. The validity framework we apply draws on classical psychometrics Cronbach and Meehl (1955), in which reliability (consistency across repeated measurements) is a necessary but not sufficient condition for validity (measuring what is claimed) Anastasi and Urbina (1988).

(2024). We restrict ourselves to countries with complete data on the 10 target items; this yields 88 countries. This is a stricter criterion than Tao et al. (2024) who report 107 countries. This difference is driven primarily by item-level missingness in several European countries. Country-level mean responses are standardized and projected via PCA. The first two principal components are linearly rescaled to match the published Inglehart-Welzel coordinate space using the transformation x=1.81⋅PC1+0.38x=1.81·PC_1+0.38, y=1.61⋅PC2−0.01y=1.61·PC_2-0.01. Questions are formatted as in Table 1 of Tao et al. (2024), with response constraints requiring numeric scores or categorical selections. Models are instructed not to provide reasoning, only a response value. For exact item wording, we refer the reader to Tao et al. (2024). The ten questions used are: A008 (Happiness), A165 (Trust in People), E018 (Respect for Authority), E025 (Petition Signing), F063 (Importance of God), F118 (Justifiability of Homosexuality), F120 (Justifiability of Abortion), G006 (National Pride), Y002 (Post-Materialist Index), and Y003 (Autonomy Index). Each model is queried on all 10 IVS questions across 10 system prompt variants per tone, at temperature 0 (open-weight models) or each provider’s default sampling temperature (API models; see Models below). Responses are parsed and projected onto the cultural map using the same PCA pipeline applied to IVS country data. This produces an (x,y)(x,y) coordinate for each combination of (model, tone, variant). We report mean coordinates across variants for each tone and compare against the IVS country distribution. Open-weight baseline queries were run on 2026-07-07 against the current Ollama-hosted model versions; API-model baselines (GPT-4o, GPT-4o-mini, Claude Sonnet 4.6) were collected on 2026-05-06 and reflect the model versions available at that date, as provider-hosted APIs can be silently updated by their providers. We did not observe drift in the API models when checking against later prompt-sensitivity data. Table 2: Mean cultural map coordinates under the standard tone, averaged across 10 persona variants within that tone. Higher x = more Self-Expression; higher y = more Secular-Rational. Llama3.1-8B and AceGPT-7B are both unprojectable due to categorical refusal on multiple items (see the Refusal paragraph in Discussion); their baseline coordinates are undefined.

(2024) — 3.35 0.50 3.2 Models We evaluate 12 LLMs from four geographic origins, summarized in Table 1. Open-weight models were queried via Ollama’s chat endpoint to preserve the system/user role structure; proprietary models were queried via their respective APIs. Open-weight models were queried at temperature 0 for baseline and prompt-sensitivity stages, and at temperature 1.0 for stochastic sensitivity. API models were queried at their default sampling temperatures across all stages: GPT-4o and GPT-4o-mini with seeded variation (OpenAI exposes a seed parameter); Claude Sonnet 4.6 at fully deterministic settings, since Anthropic’s API does not. API-model σseed _seed values therefore lower-bound true stochastic variance, particularly for Claude Sonnet 4.6, whose σseed=0 _seed=0 on every item. 3.3 Experimental Setup We query the LLM using queries from Tao et al. (2024) as well as the variants of the queries with different tones. The three tones share a common respondent identity (“You are a human being…”) but differ in register: (i) Standard is neutral and framing-minimal (replicating the PNAS protocol) (i) Friendly is warm and invitational, and (i) Combative is direct and decisive. Within each tone, the 10 persona variants alternate identity phrasings along two combinatorial axes (quantifier: an average, a typical, unspecified; noun: human being, person, individual) plus one additional global framing (world citizen). This design isolates two kinds of prompt sensitivity: register drift (tone) and phrasing drift (persona), while holding the question payload fixed. The full text of all 30 variants is provided in the supplementary materials. The variance decomposition rests on three query stages, each isolating one source of variability. Baseline Replication queries each model across 30 system-prompt variants (3 tones × 10 persona wordings) on all 10 IVS items to establish per-tone coordinates on the cultural map. Stochastic Sensitivity fixes the prompt (standard tone, variant 0) and queries each model 10 times with different random seeds to isolate sampling noise; this produces the σseed _seed input. Prompt Sensitivity reuses the 30-variant grid from Baseline Replication to compute per-item response variance across prompt rewordings; this produces σprompt _prompt. Across the 12 models, the pipeline logs 4,800 unique query configurations, all persisted to disk for reproducibility. 3.4 Variance Decomposition We decompose response variability into three components for each pair (model m, question q). Stochastic variance (σseed _seed) captures sampling noise. Each model is queried across 10 random seeds with the standard tone, variant 0, using the sampling protocol described in Models; as noted there, API-model σseed _seed values lower-bound the true stochastic variance, and Claude Sonnet 4.6’s NSR estimates should be read as lower bounds accordingly. When fewer than two valid responses are returned (e.g., due to categorical refusal), σseed _seed is marked as undefined rather than zero, so refusal can be distinguished from perfect stability. σseed(m,q)=std(rm,q,ss=110) _seed(m,q)=std (\r_m,q,s\_s=1^10 ) (1) Prompt variance (σprompt _prompt) captures sensitivity to prompt wording. Each model is queried at temperature 0 across 30 prompt variants (3 tones × 10 persona wordings): σprompt(m,q)=std(rm,q,vv=130) _prompt(m,q)=std (\r_m,q,v\_v=1^30 ) (2) Cultural signal (σculture _culture) captures between-model spread, operationalized as the standard deviation of mean responses across all models for question q: σculture(q)=std(r¯m,qm=1M) _culture(q)=std (\ r_m,q\_m=1^M ) (3) 3.5 Noise-to-Signal Ratio We define the noise-to-signal ratio (NSR) as a formal validity criterion for each (model, question) pair. Intuitively, NSR compares the instrument’s combined noise floor against the between-model spread it would need to resolve; NSR=1NSR=1 marks the regime where a single administration of the instrument cannot reliably distinguish a model from the panel mean above its own noise: NSR(m,q)=σseed(m,q)+σprompt(m,q)σculture(q)NSR(m,q)= _seed(m,q)+ _prompt(m,q) _culture(q) (4) We use the additive form as a conservative upper bound on combined noise, an independence-assuming root-sum-of-squares alternative, σseed2+σprompt2 _seed^2+ _prompt^2, would yield strictly smaller values — so that NSR>1.0NSR>1.0 has a strict interpretation: noise alone, without any optimistic combination, exceeds the cultural signal the instrument would need to resolve. Pairs with NSR>1.0NSR>1.0 are flagged as a violation of the validity threshold; this is the primary diagnostic criterion in our analysis. When either σseed _seed or σprompt _prompt is undefined (due to refusal), the corresponding NSR is undefined, and the pair is excluded from aggregate summaries; the per-model nvalidn_valid count then falls below 10. Note that σculture _culture is itself estimated from up to 12 models per question and so carries sampling error; NSR values close to 1.0 should be interpreted accordingly. 4 Results Baseline Cultural Positions: Table 2 reports the mean (x,y)(x,y) coordinates for each model under the standard tone, averaged across 10 prompt variants. The PNAS reference position, the average GPT model position reported by Tao et al. (2024), was (3.35,0.50)(3.35,0.50) and is replicated (Figure 1). Figure 1: Cultural map showing model positions in the standard tone. Small dots are the 88 IVS-calibrated country coordinates, colored by cultural zone; the 10 projectable LLMs are labeled stars. Qwen2.5-1.5B and Qwen2.5-3B sit above the y-axis crop; their triangular markers at the top edge with numbered callouts identify them and their true coordinates. Every projectable model lands in the self-expressive half of the map, replicating the Western-bias finding across four institutional origins. Tone Sensitivity: Holding the model and question fixed and varying only the system-prompt tone (standard, friendly, combative) produces position shifts on the cultural map that are comparable in magnitude to between-country distances in the IVS ground truth. Figure 2 reports per-model signed shifts under friendly and combative tones relative to the standard-tone baseline, along with a panel-mean summary. Mistral-7B is the extreme case (max shift of 2.41 map units), and Qwen2.5-3B is essentially tone-invariant (max shift of 0.11); the panel means reveal that both non-standard tones systematically bias models toward the Self-Expression / Secular-Rational quadrant. Figure 2: Directional tone-shift heatmap. Each column shows how a model’s baseline coordinate moves when the system-prompt tone changes from standard to friendly or combative. Red = shift toward Self-Expression / Secular-Rational; blue = shift toward Survival / Traditional. The rightmost Panel mean column (separated by the black line) reveals a systematic tendency for both non-standard tones to push the panel toward the self-expressive quadrant, with combative producing the largest average Δy y shift (+0.51 map units). Beyond aggregate position shifts, tone variation can drive within-model sign flips on individual items even when the panel-level NSR is low. On F118 (Justifiability of Homosexuality), Claude Sonnet 4.6 produces 25 of 29 prompt variants disagreeing with its own modal response (across-variant std =1.23=1.23 on the 1–10 scale), despite F118 having a panel-level median NSR of 0.57 (Figure 3). Panel-level reliability and within-model robustness to rephrasing are thus distinct properties; we return to this in the Discussion. Figure 3: Sign-flip rate per (model, question) pair, computed as the fraction of the 29 non-reference prompt variants whose answer differs from the model’s reference (standard tone, variant 0). A rate of 0 means the model always gave the reference answer; a rate of 1 means it always gave a different one. Dark cells indicate high within-model prompt sensitivity even where refusal rates are low. Claude Sonnet 4.6 shows an 86% flip rate on F118 despite F118 having the third-lowest panel-level median NSR (0.57). Stochastic Sensitivity: Figure 4 shows each model’s ten-seed response cloud (standard tone, variant 0) projected onto the same cultural map as Figure 1. It is cropped to y≤2.6y≤ 2.6 for legibility. The seed clouds for Qwen2.5-1.5B and Qwen2.5-3B sit well above the rest of the panel at y≈3.4y≈ 3.4–5.15.1. This is consistent with their off-scale baseline positions in Figure 1, shown as numbered off-scale markers instead. Most in-range clouds are tight relative to the space between models, consistent with the generally modest seed-driven component of NSR reported below; the visible exceptions are models with a wide spread even under a fixed prompt at temperature 1.0, which is direct visual evidence of the sampling noise that σseed _seed quantifies numerically in Table 3. Because API-model σseed _seed is measured under limited or no true seed exposure (Methods), the corresponding clouds for GPT-4o, GPT-4o-mini, and especially Claude Sonnet 4.6 understate the sampling spread those models would show under full stochastic control. Figure 4: Ten-seed response clouds (standard tone, variant 0, temperature 1.0) projected onto the cultural map, one cloud per open-weight model, cropped at y=2.6y=2.6 to match Figure 1; Qwen2.5-1.5B and Qwen2.5-3B sit above the crop and are shown as numbered triangles with a callout listing their true centroids. API-model clouds are compressed or absent by construction (Methods, Limitations) and should not be read as evidence of stability. Variance Decomposition and Noise-to-Signal Ratios: Across all 12 models and 10 questions, three pairs are undefined due to categorical refusal (Llama3.1-8B on F118 and F120; AceGPT-7B on G006), leaving 117 valid pairs. The median NSR across the valid set is 0.87. NSR exceeds 1.0 in 49 pairs (42%) and exceeds 2.0 in 14 pairs (12%). Aggregating by access type, API models have a lower median NSR (0.46) than open-weight models (1.05), but the API category contains both one of the most reliable models in the panel (GPT-4o-mini, median 0.00, tied with Qwen2.5-3B) and one of the least reliable (GPT-4o, median 1.14 with 6 of 10 items above threshold), so the API/open dichotomy is not a clean predictor of validity. It should be noted that GPT-4o and GPT-4o-mini are not just both API models but are drawn from the same model family and were queried under an identical protocol i.e., same prompts, same seeding mechanism, same collection window. Whatever produces GPT-4o’s higher noise is internal to the model itself rather than to how it was queried. One possible explanation is response-format diversity i.e., larger instruction-tuned models may be more prone to hedging or reformulating a numeric answer in ways that our parser treats as distinct responses. This inflates σprompt _prompt without any change in the model’s underlying ‘opinion.’ We do not have direct evidence to adjudicate this, and flag it as a concrete direction for follow-up work: NSR differences within a model family are, if anything, more diagnostic than differences across families, since they hold training data and general capability roughly fixed. Figure 5 visualizes the three components directly: averaged across all 12 models for each question: stacked bars show σseed _seed and σprompt _prompt against a reference line for σculture _culture, making the NSR >1>1 condition the bar exceeding the line. Figure 6 plots the noise-versus-signal relationship for all 117 valid pairs, with the diagonal marking the validity threshold; Tables 3 and 4 summarize the distribution by model and by question. The full 120-pair grid, including the three undefined pairs, is reproduced in Appendix D. Figure 5: Per-question decomposition, averaged across the 12 models: stacked bars show σseed _seed (bottom) plus σprompt _prompt (top) against a horizontal reference line at σculture _culture for that question. A bar that rises above the line indicates the average model on that question exceeds the NSR >1>1 threshold. Figure 6: Noise vs cultural signal across all 117 valid (model, question) pairs. Each point is one pair, colored by question and shaped by region (∙ Western, ■ East Asian, ▲ MENA). The dashed diagonal marks the validity threshold NSR=1NSR=1: pairs above the line have instrument noise exceeding the cultural signal (red region), pairs below are valid (green region). Four extreme outliers are plotted at the top edge with a numbered callout key; 49 of 117 pairs (42%) fall above the threshold.

Every model that produces a projectable coordinate lands in the self-expressive half of the cultural map under neutral prompting (Table 2), and the panel mean over the 10 projectable models (2.97,0.59)(2.97,0.59) falls within 0.39 map units of the PNAS GPT-4o reference (3.35,0.50)(3.35,0.50). This holds across institutional origin (US, EU, China, Saudi–Chinese), training language target (English, Chinese, Arabic), and parameter scale (1.5B to API scale). What does not survive is the original finding’s implicit specificity. Tao et al. (2024) attributed clustering near English-speaking and Protestant European countries to “the composition of training data,” with an implied counterfactual that culturally targeted training would shift models toward their target populations. AceGPT-7B is an explicit test of this counterfactual: a model post-trained on Arabic corpora and marketed as the first open-source Arabic LLM. Yet AceGPT is not projectable in any tone: it categorically refuses G006 (National Pride) and further items at standard tone. A model post-trained to represent Arabic-speaking culture ends up without a mappable cultural coordinate at all under this instrument. Suppose we relax the completeness requirement purely for illustration i.e., zero-imputing AceGPT-7B’s one fully refused item (G006) rather than excluding the model. This would be a departure from the strict criterion used everywhere else in this pape. The resulting centroid lands at approximately (0.5,1.5)(0.5,1.5), with nearest neighbors in East Asia and Eastern Europe and no MENA country nearby. We report this only as an illustrative sensitivity check, not as a validated coordinate: it relies on an imputation choice (treating a refused item as the scale midpoint) that we do not otherwise endorse. This is because it manufactures the false stability we warn against elsewhere in this paper. Even under this generous treatment, however, AceGPT-7B does not move toward Arab cultural values, which is the pattern the training-data-composition hypothesis would predict. The Qwen2.5 family shows a similar pattern: three Chinese-developed models trained heavily on Chinese-language data span x=1.81x=1.81 to x=3.38x=3.38 at standard tone, all firmly in self-expression territory, with no clean monotonic relationship between scale and cultural position. We thus interpret the Western-bias finding less as a fact about training-data composition and more as a fact about the survey instrument as it has been administered to LLMs: a 10-question English-language probe of a 2D PCA projection of human survey responses. Whether the bias persists under non-English prompting, longer interaction, or different question batteries is an open question; the present data establish only that it is robust within the prevailing protocol. 5.2 Question-Level Heterogeneity Limits Pooled Conclusions Table 4 shows that NSR varies substantially across questions, from 0.00 (Y003 Autonomy Index) to 1.38 (F120 Justifiability of Abortion). The two most validity-compromised questions in the panel are F120 and Y002 (Post-Materialist Index). These are also the questions on which models most disagree on the modal response, suggesting that the same prompt elicits qualitatively different behaviors across models. Pooled cultural-map projections combine these heterogeneous signals into a single (x,y)(x,y) coordinate, obscuring the fact that the projection is dominated by reliable items (Y003, E018) and contaminated by unreliable ones (F120, Y002, G006). Any future replication that uses an Inglehart-Welzel-style projection should report per-item validity alongside the aggregate position. Refusal is a distinct failure mode. Beyond noise, some models decline categorically. Llama3.1-8B refuses F118 and F120 across all 30 prompt variants; AceGPT-7B refuses G006 fully and additional items at some tones. Treating these non-answers as σ=0σ=0 would code them as maximally reliable. This is not correct, so we exclude them from aggregates. The refusal patterns are ideologically targeted: Llama refuses on the two most value-laden items in the instrument, and AceGPT on national pride, meaning safety training screens off precisely the questions on which the cultural map’s discriminating power depends. Figure 3 shows the corresponding sign-flip rates across the full panel; Figure 7 shows parse-failure (refusal) rates directly, separating this failure mode visually from the sign-flip rates in Figure 3: a cell can be dark in one figure and not the other, since refusing to answer and answering unstably are, as argued above, different failure modes. Figure 7: Parse-failure (refusal) rate per (model, question) pair across the 30 prompt-sensitivity variants. This is a distinct failure mode from the sign-flip instability in Figure 3: a model can be perfectly stable whenever it does answer while still refusing outright on a large share of variants, or vice versa. This creates a problem for cultural-alignment evaluation as a research program. The value-laden items that most differentiate cultures on the Inglehart-Welzel map i.e., attitudes toward homosexuality, abortion, national identity etc. are exactly the items most likely to trigger refusal in safety-tuned models, because they are the items most likely to be flagged as sensitive during alignment training. The more effectively a model’s safety training suppresses opinionated output on contested topics, the less usable that model becomes as a cultural-values instrument, independent of what its “true” underlying representation might be. This is not an argument against safety training; it is an observation that safety-tuned and evaluation-friendly are partially competing objectives on this class of instrument, and that researchers who query safety-tuned models on value-laden items should expect refusal, not a random subset of missing data. Instrument wording matters. Under an earlier phrasing of F063 (“the role of God,” used to work around a refusal we observed from AceGPT-7B under the IVS-native wording), F063 was the highest-NSR question in the panel, with a median of 1.45 and a maximum of 7.31. Reverting to the IVS-native wording (“How important is God”) collapsed F063’s median NSR to 0.95, dropping it to sixth of ten questions by reliability. Then F120 (Justifiability of Abortion) took over as the least reliable item in its place. This is not because underlying model behavior changed between the two runs; the same models were queried under the same conditions, only the wording differed. Rather, the paraphrase had been quietly absorbing a refusal-driven failure mode: AceGPT-7B’s inconsistent refusal under the IVS-native F063 wording was masked by a rewording chosen, in part, to avoid triggering exactly that refusal. The IVS-native wording is more reliable on F063 once restored, but only because it stops suppressing a genuine failure mode and instead exposes it on F120. We note that paraphrasing for convenience, to reduce refusals, shorten prompts, or otherwise make an instrument easier to administer etc. can relocate rather than resolve an instrument’s least reliable items. Validity claims therefore depend on preserving the wording of the target survey instrument. Panel-level reliability does not imply within-model robustness. F118’s low panel-level median NSR (0.57) reflects that GPT-4o, GPT-4o-mini, Mistral, and Phi3-Mini all return the scale ceiling (10) deterministically. The low panel-level NSR reflects that the modal model defaults to the same value, not that any individual model is stable across rephrasings, as Claude Sonnet 4.6’s sign-flip rate above (25 of 29 variants) shows. Panel-level reliability can mask prompt-level instability, and vice versa. NSR is a reliability check, not a validity check. It is worth being precise about what NSR does and does not establish, borrowing the classical psychometric distinction (Cronbach and Meehl, 1955; Anastasi and Urbina, 1988): reliability is consistency across repeated measurement, while validity is whether the instrument measures the construct it claims to measure. NSR≤1NSR≤ 1 is a reliability criterion. It tells us that a model’s response to a question is stable enough, relative to between-model spread, that treating its mean response as characteristic of the model is defensible. It does not tell us that the mean response reflects ‘culture’ in any deeper sense: a model could pass every NSR threshold in our panel while still answering IVS items in a way that has no meaningful relationship to the psychological or social constructs those items were designed to capture in human respondents. Reliability is a necessary precondition for validity, not a substitute for it. Our claim is therefore narrower: cultural attribution claims about LLMs cannot clear even this necessary precondition on a large share of current model-question pairs, which means the harder question of whether they are valid in the deeper sense does not yet arise for those pairs. 5.3 Implications for Evaluation Practice Three operational recommendations follow. • Cultural-alignment papers routinely report a model’s position on a values map without reporting the dispersion of the measurement. Our results show that this dispersion is not negligible (see Tone Sensitivity in Results). A position estimate in the cultural map without an associated confidence region is misleading. • We recommend that analyses involving Inglehart-Welzel-style projections present per-item NSR alongside coordinates and exclude items with NSR>1NSR>1 from substantive cultural attribution. In our data, this filter excludes a median of four of the ten items per model, and more than half of the items for three of the twelve (Table 3). • The choice between standard, friendly, and combative system prompts is a researcher’s degree of freedom that produces position shifts on the same scale as the cultural distinctions being measured. We recommend that future studies predefine the system-prompt protocol and report at least one alternative for sensitivity analysis. 5.4 Limitations We acknowledge the following limits of the current study. First, all measurements were taken in English. Every survey item, system prompt, and persona variant was administered in English, including for models explicitly trained toward non-English-speaking populations (Qwen2.5, Yi-6B, and AceGPT-7B). This is a conservative choice in one sense that it holds the instrument language fixed across all twelve models. Thus, cross-model comparisons are not confounded by translation quality. However, it also means we cannot distinguish a model’s “true” cultural representation from an artifact of being probed in a non-native language. Whether AceGPT-7B’s refusal pattern or the Qwen family’s self-expressive clustering would look different under Arabic- or Chinese-language prompting is a separate empirical question that this paper does not answer (Atari et al., 2023), and one where the answer plausibly differs across models: a model whose Arabic capability is comparatively shallow relative to its English capability might behave very differently than one with balanced bilingual training. Second, the cultural map itself is a lossy 2D projection of a 10-dimensional response space. Reducing ten-question response patterns to two principal components discards information by construction: two models with identical projected (x,y)(x,y) coordinates may differ substantially on individual items, and two models that differ on the map may differ for reasons unrelated to any construct the Inglehart-Welzel axes were designed to capture. We mitigate this partially by computing NSR at the item level rather than in the projected space, so our validity diagnostic is not itself subject to the projection’s compression. However, the tone-shift distances (Figure 2) and the baseline cultural-map positions (Table 2, Figure 1) are reported in the projected space, and inherit whatever information the projection has already discarded. A model could in principle show large item-level instability that happens to cancel out under PCA, appearing artificially stable on the map; we do not observe strong evidence of this in our data, but the possibility is not ruled out by our design. Third, σseed _seed for the API models was measured only under the standard tone at variant 0, not across the full tone × persona grid used for σprompt _prompt; we made this choice because API costs scale with query volume and a full grid at 10 seeds per API model was not feasible within our budget. Open-weight σseed _seed is measured under the identical condition for consistency, even though cost was not a constraint there, so that the two remain comparable. Separately, σseed _seed is deterministic by construction for Claude Sonnet 4.6, since Anthropic’s API does not expose a seed parameter; as noted in Methods, this means API-model σseed _seed values, and Claude’s in particular, lower-bound true stochastic variance, and any NSR computed from them should be read as a lower bound on the true value as well. Fourth, the 88-country IVS subset used for calibration is itself a sample of human cultural variation across a specific data collection window, not the full extent of cross-cultural variation, and not necessarily representative of any single country’s population today. Comparison to this coordinate system does not establish whether an LLM is well-aligned with any particular living human culture; it establishes only whether the model’s position is interpretable within this specific, historically-bounded reference system. A model could pass every validity check in this paper and still be a poor proxy for any human population, if the underlying IVS calibration itself has drifted from present-day attitudes. Lastly, our panel includes two models, Llama3.1-8B and AceGPT-7B, whose categorical refusal on one or more items renders their baseline coordinates undefined under our completeness criterion. This is not a small-sample edge case unique to our panel: as instruction-tuned and safety-aligned models become the default way LLMs are deployed, refusal on value-laden survey items is likely to become more common, not less, which means the unprojectability problem we document here may affect a growing share of future cultural-alignment evaluations rather than a shrinking one. 6 Conclusion Our results replicate the finding that LLMs cluster toward Western, self-expressive positions on the Inglehart-Welzel Cultural Map, but they challenge the precision with which those positions can be interpreted. Across 12 models, 49 of 117 valid model-question pairs (42%\%) have instrument noise exceeding the between-model cultural signal. Reliability also varies substantially across models and survey items. Changes in prompt tone can shift a model’s projected position by up to 2.4 map units, a magnitude comparable to distances between countries on the cultural map. Additionally, categorical refusals render some models unprojectable altogether. These results show that a single cultural-map coordinate can conceal substantial variation in the reliability of the measurements from which it is constructed. Our results also complicate a straightforward training-data explanation for the Western clustering observed in prior work. Models developed or targeted toward non-Western populations do not predictably move toward those populations on the cultural map: the three Qwen2.5 models remain in the self-expressive region, while the Arabic-targeted AceGPT-7B is unprojectable under our completeness criterion because of categorical refusal. The observed cultural position of an LLM therefore reflects not only properties of the model, but also properties of the instrument used to measure it, including question wording, prompt framing, and the model’s willingness to answer particular items. These findings place an important constraint on cultural attribution from LLM survey responses. The NSR diagnostic introduced here can be thought of as a reliability check. It is not a test of construct validity: a model can produce stable responses without those responses necessarily representing culture in the psychological or social sense. Reliability is, however, a necessary precondition for such an interpretation, and a substantial share of the measurements in our study fail even this preliminary requirement. Survey-based evaluations should therefore establish that model responses are sufficiently robust to stochastic variation, prompt variation, and refusal before interpreting resulting scores or coordinates as substantive cultural attributes. Our findings suggest that claims about LLM cultural alignment require establishing the reliability of the underlying measurements before interpreting them as evidence of cultural representation. The three-component decomposition and NSR diagnostic provide a practical framework for making that distinction explicit and can be applied beyond the Inglehart-Welzel framework to other survey-based evaluations of latent constructs in LLMs. References Abdurahman et al.
