Synthetic Cultural Agents from Aggregate Anchors

The paper proposes a new method for generating synthetic survey responses that uses declared aggregate preference anchors to create group-indexed choice policies, avoiding the mixing of inference-time information with pretraining associations. It introduces a parameter‑efficient adapter trained via Direct Preference Optimization to map GPS coordinates to synthetic responses, and evaluates these adapters on World Values Survey items, showing they recover imposed labels and exhibit strong correlation with GPS trust scores. The study demonstrates that anchored policies can preserve aggregate signals while not necessarily mirroring human response patterns, offering an inspectable construction and evaluation framework that separates anchor transfer from human criterion agreement.

Prompts to Proxies: Emulating Human Preferences via a Compact LLM Ensemble

The paper introduces Prompts to Proxies (P2P), a two‑stage inference‑time system that uses structured attribute‑based prompting and entropy‑guided sampling to build a diverse proxy pool, followed by L1‑regularized regression to create a compact weighted ensemble that matches aggregate survey responses. P2P achieves low mean squared error on American Trends Panel data and competitive performance on World Values Survey cross‑locale experiments, outperforming baseline prompting and demographic‑conditioning methods while using minimal training data. The authors argue that this preference reconstruction approach offers a lightweight, externally verifiable alternative for aligning large language model proxies with target human populations.

Investigating Multi-Cultural Value Selection Biases in LLMs

The study examines how large language models (LLMs) respond to simultaneous cultural identity cues, comparing explicit country names with implicit language cues. Using World Values Survey probing and open‑ended sociopolitical generation, it finds that language cues shift responses more than explicit cues but not toward the named country’s distribution, while explicit cues produce more differentiated value changes. Across 1.6 million responses, naming a country narrows the gap to the model’s own country‑specific answers by 30–44%.

PLURAL: A Global Dataset for Value Alignment

Large language models (LLMs) are used worldwide, yet disproportionately reflect Western values, limiting their ability to represent diverse value systems. We introduce PLURAL, a large-scale, value-focused preference dataset grounded in the Integrated Values Survey (IVS), a nationally representative survey spanning 92 countries.

Cultural Alignment in Large Language Models Using Soft Prompt Tuning

The paper proposes a method for culturally aligning large language models (LLMs) using soft prompt tuning optimized via Differential Evolution (DE). Unlike traditional fine‑tuning or reinforcement learning, this approach keeps model weights frozen and requires no preference data, instead leveraging aggregated survey scores from Hofstede's Value Survey Module (VSM13). Experiments on four countries and four instruction‑tuned models show that DE‑optimized prompts reduce cultural discrepancy, improve agreement with the World Values Survey, and are preferred in blinded pairwise evaluations by LLM judges.

Cultural Divergence Preservation: Diagnosing Flattening and Caricature in LLM-Simulated Survey Populations

The paper introduces Cultural Divergence Preservation (CDP), a new diagnostic for evaluating whether large language models (LLMs) preserve cross‑country differences when used as synthetic survey respondents. CDP uses a single human calibration to detect cultural flattening (reduced divergence) or caricature (increased divergence) and is shown to vary monotonically with cross‑country divergence, unlike conventional Jensen–Shannon divergence metrics. Experiments across multiple LLM backbones, prompting methods, and survey domains reveal that CDP uncovers systematic discrepancies with traditional fidelity metrics, highlighting that methods favored by those metrics can still produce strong flattening.

Population Fidelity: Evaluating Population Representativeness in LLMs

The paper introduces Population Fidelity, an evaluation framework for assessing how well large language models (LLMs) represent human population attitudes. It focuses on three dimensions: group-level accuracy, between-group variation, and the structure of that variation. Using the framework, the authors replicate a prior study on machine bias and test cultural fine-tuning, finding that while fine-tuning improves overall alignment, it does not enhance representation of within-population differences.

DiverValue-Bench: A Benchmark and Fine-Tuning Framework for Aligning Large Language Models with Diverse Human Values

arXiv:2509. 08022v3 Announce Type: replace-cross Abstract: Aligning large language models (LLMs) with diverse human values is essential for safe and effective deployment, yet existing benchmarks often overlook cultural and demographic variation.

When Persona Attributes Improve Population Alignment in Large Language Models

The paper investigates how persona prompting—using short textual descriptions of individuals—to align large language models (LLMs) with human survey responses. It examines the impact of selecting different persona attributes and finds that not all attribute combinations improve performance, suggesting that the variation in human responses to survey questions may explain mixed results. The study evaluates multiple attribute selection methods across four social surveys, two countries, six LLMs, and twenty prediction tasks, offering guidance on when persona prompting is beneficial and which attribute choices are most effective.
