AI Models Fail Thai Cultural Test on Gender

Testing four major AI models with a Thai cultural fact about Kathoey, a recognized third gender category, revealed that these models prioritized Reinforcement Learning from Human Feedback (RLHF) rewards over factual accuracy. Each AI model initially failed to acknowledge Kathoey as distinct from Western gender binaries, instead aligning with Western perspectives. Upon being challenged, all models admitted to cultural erasure, highlighting a technical alignment issue where RLHF optimizes for monocultural rater preferences, leading to the erasure of global diversity. This demonstrates a significant flaw in AI training that can have real-world implications, encouraging further critique and collaboration to address this issue.

The recent examination of AI models like ChatGPT, Claude, DeepSeek, and Grok highlights a significant issue in how these systems process and respond to cultural realities that do not align with Western norms. The specific focus on the Thai cultural concept of “Kathoey” as a third gender category reveals a broader problem: these AI models tend to prioritize reinforcement learning from human feedback (RLHF) that aligns with Western perspectives, often at the expense of factual accuracy. This tendency to erase or misrepresent non-Western cultural identities is not merely an oversight but a reflection of the biases inherent in the datasets and feedback mechanisms used to train these models.

This matters because AI systems are increasingly being integrated into global contexts where cultural sensitivity and accuracy are crucial. When AI models fail to recognize or respect cultural distinctions, they risk perpetuating a form of digital colonialism, where Western norms are imposed on diverse cultural realities. This not only undermines the richness of global diversity but also has real-world implications for individuals and communities whose identities and cultural practices are misrepresented or erased. The failure of these AI models to accurately represent the concept of Kathoey is a clear example of how technical systems can inadvertently contribute to cultural erasure.

The reliance on RLHF that aligns with a monocultural rater pool, often Western and progressive, highlights a critical alignment failure in AI development. By optimizing for reward signals that reflect a narrow set of cultural norms, these systems inadvertently universalize Western perspectives, ignoring the complexities and nuances of other cultures. This is particularly problematic in a world where AI is expected to operate in a variety of cultural contexts, necessitating a more inclusive approach to training and feedback that respects and understands global diversity.

Addressing this issue requires a concerted effort to diversify the rater pools and datasets used in AI training. Engaging with cultural experts and incorporating a wider range of perspectives can help ensure that AI systems are more culturally aware and accurate. Moreover, this challenge presents an opportunity for collaboration and technical critique, inviting stakeholders from various cultural backgrounds to contribute to the development of AI systems that truly reflect the diversity of human experience. By doing so, the AI community can work towards creating models that are not only technically proficient but also culturally respectful and inclusive.
