A recent study sheds light on systemic biases in popular AI language models like ChatGPT when processing queries involving names suggestive of race or gender. Stanford Law School Professor Julian Nyarko and his co-authors investigated how these models, despite their widespread use, often yield different outcomes based on the perceived race or gender associated with certain names.
For instance, when prompted with inquiries such as pricing advice for a bicycle being sold by someone with a black-sounding name versus a white-sounding name, ChatGPT-4 tended to offer significantly lower estimates for the former. This disparity extended to various scenarios, with names linked to black women receiving the least favourable outcomes, highlighting pervasive biases within these models.
The study, titled “What’s in a Name? Auditing Large Language Models for Race and Gender Bias,” employed an audit design framework to examine biases across different domains, mirroring methodologies used in studies of societal disparities. By analyzing responses to prompts across multiple scenarios, the researchers identified consistent biases, indicating systemic issues rather than isolated incidents.

Despite the closed-source nature of many leading AI language models, the study adopted innovative approaches to investigate biases indirectly. While previous studies primarily focused on binary outcomes, such as employment decisions, this research explored nuanced biases by framing queries in open-ended scenarios.
The disparities uncovered by the study were notable across various prompt templates and models, revealing implicit biases deeply ingrained in the training data. While numerical anchors in prompts helped mitigate biases, qualitative details sometimes exacerbated disparities, underscoring the complexities in addressing biases within AI language models.
Moving forward, the study advocates for increased awareness and testing for biases in language models, particularly as they become increasingly integrated into various applications. While technical solutions to mitigate biases are still evolving, it emphasizes the importance of conscious decision-making in model design and deployment to ensure fair and equitable outcomes for all users.
