Accurate in space, unreliable in time: how LLMs represent national cultural change

Recent research from arXiv:2609.01902v1 indicates that Large Language Models (LLMs) are proficient at representing national cultural alignment at a given point in time but demonstrate unreliability in accurately capturing how cultural values change over historical periods. Current evaluation methods for LLMs predominantly treat culture as static, overlooking the dynamic nature of cultural evolution identified by cultural psychology.

The accurate representation of cultural change over time is crucial for LLMs, as their applications increasingly intersect with diverse global contexts requiring nuanced historical and societal understanding. Failing to account for cultural evolution could lead to misinterpretations, biased outputs, and ineffective or inappropriate interactions in domains where cultural sensitivity and historical context are paramount.

Assessments of cultural alignment are critical for LLM development and improvement.
