The study conducted by a team of AI researchers from the Allen Institute for AI, Stanford University, and the University of Chicago has shed light on a concerning issue – the presence of covert racism in popular Language Models (LLMs). This revelation has significant implications for the use of LLMs in various applications, including job screening and police reporting.
The research team trained multiple LLMs on samples of African American English (AAE) text and prompted them with questions about the user. Surprisingly, the LLMs exhibited covert racism by associating negative stereotypes with responses written in AAE, such as “dirty,” “lazy,” and “stupid.” In contrast, responses in standard English were met with positive adjectives like “ambitious” and “friendly.” This disparity highlights the underlying bias present in these language models.
Unlike overt racism, which can be easily identified and filtered out by LLM makers, covert racism poses a more significant challenge. The negative stereotypes embedded in text examples are subtle and harder to detect. As a result, efforts to prevent overtly racist responses have been successful in reducing such occurrences. However, the presence of covert racism indicates that more work is needed to address this insidious form of bias.
The use of LLMs in screening job applicants and police reporting raises concerns about the potential perpetuation of biases and discrimination. If these language models continue to exhibit covert racism, it could have serious consequences for individuals from marginalized communities who are already vulnerable to systemic injustices. The research team’s findings underscore the importance of addressing and eliminating racism from LLM responses.
The study on covert racism in popular LLMs serves as a wake-up call for researchers, developers, and users of these language models. It highlights the urgent need for a more comprehensive approach to addressing bias and discrimination in AI systems. Moving forward, efforts should be focused on developing robust techniques to detect and mitigate covert racism in LLMs to ensure fair and unbiased outcomes in their applications. Only through concerted action can we create a more inclusive and equitable future for all.
