[2507.09650] Cultivating Pluralism In Algorithmic Monoculture: The Community Alignment Dataset
Summary
This paper presents the Community Alignment Dataset, which aims to address the challenge of aligning large language models (LLMs) with diverse human preferences across cultural and political dimensions, revealing significant variability in human preferences compared to LLM res...
Why It Matters
As LLMs increasingly influence decision-making across various sectors, understanding and incorporating diverse human preferences is crucial. This research highlights the limitations of current methods in capturing this diversity and proposes a new dataset that can enhance LLM effectiveness for a global audience.
Key Takeaways
- Humans exhibit greater variability in preferences than current LLMs can accommodate.
- Existing preference dataset collection methods are inadequate for capturing diverse human values.
- Negatively-correlated sampling can significantly improve alignment methods for heterogeneous preferences.
- The Community Alignment Dataset is the largest multilingual preference dataset to date, with over 233,000 comparisons.
- This dataset aims to enhance LLM performance for a diverse global population.

To advance this challenge, this paper establishes four key results. First, we demonstrate, through a large-scale multilingual human study with representative samples from five countries (N=15,000), that humans exhibit substantially more variation in preferences than the responses of 21 state-of-the-art LLMs. Second, we show that existing methods for preference dataset collection are insufficient for learning the diversity of human preferences even along two of the most salient dimensions...
