SubgroupValuesSG model outputs

Model outputs for "Can Persona-Prompted LLMs Emulate Subgroup Values? An Empirical Analysis of Generalisability and Fairness in Cultural Alignment" (ACL 2026).

Paper (ACL Anthology) · Code

Answers of the 18 evaluated models (seven open-source models before and after SFT, and four GPT models) to the persona-prompted survey questions, and the LLM judge's verdicts on their open-ended answers. Together with the code repository, which recreates the dataset from the official WVS file, they reproduce every table in the paper on a CPU. The judge's reasoning is omitted; only each verdict's final JSON is kept.

  abstract = {Despite their global prevalence, many Large Language Models (LLMs) are aligned to a monolithic, often Western-centric set of values. This paper investigates the more challenging task of fine-grained value alignment: examining whether LLMs can emulate the distinct cultural values of demographic subgroups. Using Singapore as a case study and the World Values Survey (WVS), we examine the value landscape and show that even state-of-the-art models like GPT-4.1 achieve only 57.4\% accuracy in predicting subgroup modal preferences. We construct a dataset of over 20,000 samples to train and evaluate a range of models. We demonstrate that simple fine-tuning on structured numerical preferences yields substantial gains, improving accuracy on unseen, out-of-distribution subgroups by an average of 17.4\%. These gains partially transfer to open-ended generation. However, we find significant pre-existing performance biases, where models better emulate young, male, Chinese, and Christian personas. Furthermore, while fine-tuning improves average performance, it widens the disparity between subgroups when measured by distance-aware metrics. Our work offers insights into the limits and fairness implications of subgroup-level cultural alignment.},
