Cultural Mishmash: Exploring Origins and Effects of Cultural Inconsistencies in Large-scale Language Models
In the rapidly evolving world of artificial intelligence, the cultural alignment of large language models (LLMs) has become a topic of increasing concern. Recent research reveals that these models, far from being culturally neutral, often reflect and convey specific cultural values, cognitive styles, and biases embedded in their training data and design.
A study analyzing responses generated by popular LLMs such as GPT and ERNIE found that the models' outputs in different languages reflect distinct cultural orientations. For instance, GPT when responding in Chinese is more likely to recommend content with an interdependent social orientation, aligning with Chinese cultural values, versus the independent orientation typical in English responses. This indicates that LLMs inherently encode cultural tendencies rather than producing culturally neutral outputs [1].
Researchers have also demonstrated that prompting LLMs to adopt a specific cultural perspective can adjust the cultural alignment of their outputs. However, this strategy does not fully eliminate embedded biases [1].
Investigations into biases against Arabs and Muslims reveal that these prejudices in LLMs stem from the Western-centric training data and historical frameworks such as Orientalism—longstanding patterns of exoticizing and othering these cultures. While prompt engineering techniques can temporarily redirect models away from default Western perspectives, they do not fundamentally address the deep-seated biases in the models’ knowledge representations [2].
A dual-layered assessment of various LLMs from different countries (e.g., Korea, China, Japan, USA) revealed that language strongly influences model responses, and geopolitical biases surface especially in interpretive or disputable topics aligned with the model’s national origin. This suggests that LLMs’ cultural alignment and biases may vary significantly depending on their training context and deployment language [3].
The dominance of a few Western-based companies in the LLM market fosters an "algorithmic monoculture," where the models tend to reflect Western-centric cultural values due to centralized control, limited diversity in training data, and fine-tuning strategies. This market dynamic constrains the development of culturally diverse or neutral models, posing a challenge for global cultural alignment [5].
In sectors like mental healthcare and education, the cultural incompatibility of LLMs can impact their effectiveness across different communities. To address this issue, greater investment towards low-resource language models, multilingual models, and initiatives to collect more multilingual data from diverse places could create a more value-variant marketplace for LLMs.
The desired outcome of greater cultural alignment in language models is harder to imagine, as each culture fractures into smaller and smaller clusters, making true cultural alignment an endlessly receding horizon. However, the need for culturally aware evaluation and development of LLMs remains crucial to ensure they reflect the values and beliefs of users outside Western countries.

- In order to ensure that language models are more culturally inclusive, it is essential to invest in the development of low-resource language models and collect multilingual data from diverse regions, addressing the current monoculture dominance in the language model market.
- The diversity-and-inclusion initiatives in the finance sector can benefit from applying similar strategies to the language models they use in business, technology, and other areas, as the cultural alignment of these tools can significantly impact their effectiveness across various communities.
