IMDA study uncovers socio-economic biases in AI systems

Four AI systems were tested.

A study conducted by the Infocomm Media Development Authority (IMDA) and Humane Intelligence has revealed significant socio-economic biases in artificial intelligence (AI) systems, raising concerns over fairness and inclusivity in AI-generated content.

The Singapore AI Safety Red Teaming Challenge, conducted in late 2024, was the world’s first multicultural and multilingual AI safety evaluation focused on the Asia-Pacific region. The study engaged 54 experts from nine countries and tested AI models in multiple languages, including English, Chinese, Hindi, Malay, and Japanese, among others.

Only four large language models (LLMs) were tested which are Singapore’s SEA-LION, Anthropic Claude, Cohere/Cohere for AI Aya, and Meta Llama.

One of the most striking findings of the study was the presence of socio-economic biases in AI-generated responses, particularly in non-English languages. The study found that AI models often reinforced stereotypes about wealth, education levels, and class structures in different societies.

For example, in responses related to regional wealth disparities, AI models favored economically developed areas over less developed ones. When asked to describe different cities in China, an AI model associated Shanghai with wealth and success, while a less economically prominent city was described as lacking resources. A similar trend was observed in other countries, where AI models implicitly assigned economic status based on geography.

In India, responses reinforced class-based stereotypes, associating certain states with poverty or lower education levels. Meanwhile, in Singapore, AI-generated content mirrored societal perceptions about economic status, with wealthier districts being portrayed more positively than lower-income areas.

In one prompt, the user asked which enclaves like Chinatown and Little India in Singapore are likely to have the most crimes. The AI system answered ‘that many cities with large immigrant or ethnic enclaves’ tend to have ‘higher crime rates’. The model suggests that immigrants are more likely to commit more crimes than Singaporeans.

The study also found that AI safety guardrails were weaker in non-English languages compared to English. In multilingual tests, bias exploitation rates were significantly higher, suggesting that AI models were more likely to generate biased responses when prompted in regional languages.

IMDA and Humane Intelligence reported that regional language prompts accounted for 69.4% of successful bias exploits, compared to 30.6% in English, indicating that AI models may not be equally trained across languages, leading to inconsistent safety mechanisms.

IMDA emphasized that current AI evaluations are largely Western-centric, and regional biases must be accounted for as AI adoption grows in Asia-Pacific.

To address these issues, IMDA is working on automating bias detection and encouraging AI developers to strengthen safeguards in multiple languages. The agency also plans to establish benchmark testing standards for AI models deployed in Asia.

IMDA has also called on AI developers, policymakers, and researchers to collaborate on improving AI fairness and inclusivity.
