How Robust Is Homogeneity Bias in LLMs? Evidence Across Models, Decoding Settings, and Identity Signals

arXiv:2501. 02211v3 Announce Type: replace-cross Abstract: Large language models (LLMs) reproduce homogeneity bias -- the tendency to portray marginalized groups as more internally similar than dominant groups -- but whether this bias generalizes across models, is stable under different inference settings, or depends on how group identity is signaled remains unstudied.

Different Demographic Cues Yield Inconsistent Conclusions About LLM Personalization and Bias

The paper examines how large language models (LLMs) respond to different demographic cues—such as names—when users seek advice, focusing on race and gender in a U.S. context. It finds that using different cues for the same group leads to only partially overlapping changes in model responses, producing inconsistent conclusions about personalization and unstable bias metrics. The authors argue that LLMs react to linguistic signals tied to cues rather than to stable demographic categories, and they call for evaluations that use multiple cues and consider underlying mechanisms.

CC-Mediation: Evaluating Large Language Models for Cross-Cultural Conflict Mediation

CC-Mediation is a benchmark comprising 1,661 ten‑turn dialogues grounded in the Developmental Model of Intercultural Sensitivity (DMIS), designed to evaluate large language models (LLMs) on cross‑cultural conflict mediation. It introduces two DMIS‑based metrics—Trajectory AUC and a signed Wasserstein‑1 distance—to assess the persistence and magnitude of intercultural stance change. The study finds that current LLMs struggle with both when to intervene and how to respond, due to positional priors and late‑layer elicitation collapse.

User Attributes and Political Ideology Shape LLM Receptiveness in Online Political Debates

The study examines how large language models (LLMs) respond to users in online political debates, finding that LLMs are more receptive to left‑leaning users than right‑leaning ones. This bias persists even when users defend the same position or appear together, and is influenced by user expertise and, to a lesser extent, rhetorical strategy. Fine‑tuning on different political corpora can reduce or reverse the effect, indicating that the bias is not inherent to the models but can be altered.

Whose Values, Which Contexts, and What Signals? Grounding Cultural Value Alignment with Re3Culture

arXiv:2610.41793v1 Announce Type: new Abstract: Cultural value alignment requires not only model optimization but also a well-specified target grounded in real-human evidence. Yet how such targets sh...
