The Culture Funnel: You Can't Align What isn't in the Data
Current cultural alignment approaches focus on inference-time interventions, assuming models already contain sufficient cultural knowledge. This paper argues modern LLM pipelines suffer from a 'cultural data funnel,' where explicit cultural signals decline sharply during post-training, while geographically concentrated, task-specialized data dominates. Multilinguality enhances geographic diversity but does not ensure balanced representation. The authors release a culturally tagged dataset with 5.6M samples to facilitate further research.

Abstract:Current cultural alignment approaches focus on inference-time interventions, assuming models already contain sufficient cultural knowledge. We argue modern LLM pipelines suffer from a cultural data funnel. Using a multidimensional tagging framework across pretraining, fine-tuning, alignment, and reasoning datasets, we show explicit cultural signals decline sharply during post-training, while geographically concentrated, task-specialized data dominates. Multilinguality enhances geographic diversity of cultural knowledge but does not ensure balanced representation. Our tags improve downstream cultural benchmark performance, demonstrating that advances require shifting focus in training data pipelines. To facilitate future research, we release our culturally tagged dataset with 5.6M samples at this https URL.
