Cultural Adaptation in Large Language Models for Political Discourse

2026-05-22

AI Summary

This study addresses the systematic biases introduced by large language models in cross-cultural political discourse analysis, stemming from Anglocentrism, insufficient multilingual coverage, and narrow assumptions about political institutions—biases that undermine democratic accountability. It offers the first systematic characterization of cultural failure modes in political NLP and proposes a formal framework for cultural adaptation structured across three layers: translation, discourse, and ontology. The work further introduces an evaluation matrix grounded in cultural fidelity, calibration, and democratic safety. Through participatory data development, culture-aware transfer learning, and cross-cultural pragmatic analysis, the project establishes an actionable methodology and benchmarking system for culturally adaptive political AI, thereby providing both theoretical foundations and governance boundaries for the trustworthy and legitimate deployment of cross-cultural political artificial intelligence.

Abstract

The integration of large language models into political discourse analysis creates new opportunities for comparative research, policy analysis, and civic technology, while introducing material risks for democratic accountability. This paper argues that cultural adaptation is a prerequisite for trustworthy deployment of large language models in political communication across diverse linguistic and institutional contexts. Current systems remain shaped by English dominant data, uneven multilingual coverage, and assumptions grounded in a narrow range of political institutions and discourse conventions, producing systematic errors when applied across cultures. We formalize cultural adaptation across translation, discourse, and ontology levels, identify recurring cultural failure modes in political NLP, and propose an operational evaluation matrix grounded in cultural fidelity, calibration, and democratic safety. Building on political text analysis, sociotechnical auditing, and cross cultural pragmatics, we outline methodological pathways including participatory dataset development, culturally aware transfer learning, and benchmark design that makes cultural adaptation empirically measurable. We conclude by clarifying governance constraints and scope conditions under which culturally adaptive political NLP can support democratic legitimacy.
