DVMap: Fine-Grained Pluralistic Value Alignment via High-Consensus Demographic-Value Mapping

Deyi Xiong, Lei Yang, Pengyun Zhu, Yuqi Ren, Zhen Wang

Mapping multi-dimensional demographics to values lets LLMs align with pluralistic preferences more tightly than national labels allow.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experimental results demonstrate that DVMap effectively learns the manifold mapping from demographics to values, exhibiting strong generalization and robustness. On cross-demographic tests, Qwen3-8B-DVMap achieves 48.6% accuracy, surpassing the advanced open-source LLM DeepSeek-v3.2 (45.1%).

C2weakest assumption

That respondents with consistent value preferences under identical demographics form high-consensus groups whose preferences generalize reliably to unseen demographic combinations, countries, and value dimensions without introducing selection bias from the filtering process.

C3one line summary

DVMap extracts high-consensus demographic groups from survey data and applies structured CoT plus GRPO to align LLMs with pluralistic values, reporting 48.6% accuracy on cross-demographic generalization tests.
