• Title: Whose Morality Do They Speak? Unraveling Cultural Bias in Multilingual Language Models
• Authors: Meltem Aksoy,
• Abstract summary: Large language models (LLMs) have become integral tools in diverse domains, yet their moral reasoning capabilities remain underexplored. This study investigates whether multilingual LLMs, such as GPT-3.5-Turbo, reflect culturally specific moral values or impose dominant moral norms. Using the updated Moral Foundations Questionnaire (MFQ-2) in eight languages, the study analyzes the models' adherence to six core moral foundations.

• Abstract: Large language models (LLMs) have become integral tools in diverse domains, yet their moral reasoning capabilities across cultural and linguistic contexts remain underexplored. This study investigates whether multilingual LLMs, such as GPT-3.5-Turbo, GPT-4o-mini, Llama 3.1, and MistralNeMo, reflect culturally specific moral values or impose dominant moral norms, particularly those rooted in English. Using the updated Moral Foundations Questionnaire (MFQ-2) in eight languages, Arabic, Farsi, English, Spanish, Japanese, Chinese, French, and Russian, the study analyzes the models' adherence to six core moral foundations: care, equality, proportionality, loyalty, authority, and purity. The results reveal significant cultural and linguistic variability, challenging the assumption of universal moral consistency in LLMs. Although some models demonstrate adaptability to diverse contexts, others exhibit biases influenced by the composition of the training data. These findings underscore the need for culturally inclusive model development to improve fairness and trust in multilingual AI systems.

  Moral reasoning is a complex cognitive process shaped by individual experiences and cultural contexts. We bridge this gap with UniMoral, a unified dataset integrating psychologically grounded and social-media-derived moral dilemmas. We demonstrate UniMoral's utility through a benchmark evaluations of three large language models (LLMs) across four tasks.

  Cultural biases in multilingual datasets pose significant challenges for their effectiveness as global benchmarks.

We release Global MMLU, an improved MMLU with evaluation coverage across 42 languages.

  Language models can, to a limited extent, represent moral norms in a variety of cultural contexts. This study evaluates the effectiveness of these models using information from two surveys, the WVS and the PEW, that encompass moral perspectives from over 40 countries. The results show that biases exist in both monolingual and multilingual models, and they typically fall short of accurately capturing the moral intricacies of diverse cultures.

  This paper builds on the moral machine experiment (MME) to investigate the moral preferences of five large language models in a multilingual setting. We generate 6500 scenarios of the MME and prompt the models in ten languages on which action to take. Our analysis reveals that all LLMs inhibit different moral biases to some degree and that they not only differ from the human preferences but also across multiple languages within the models themselves.

Our analysis explores the alignment of 19 different LLMs with human judgments, capturing preferences across six moral dimensions. We discover significant variance in alignment across languages, challenging the assumption of uniform moral reasoning in AI systems.

  We investigate the extent to which monolingual English language models contain knowledge about moral norms in different countries. We perform our analyses with two public datasets from the World Values Survey and PEW global surveys on morality. We find that pre-trained English language models predict empirical moral norms across countries worse than the English moral norms reported previously.

  Massively multilingual sentence representations are trained on large corpora of uncurated data. This may cause the models to grasp cultural values including moral judgments from the high-resource languages. The lack of data in certain languages can also lead to developing random and thus potentially harmful beliefs.
