A recent study by a team of AI researchers has shed light on the problematic issue of covert racism exhibited by popular Language Models (LLMs). This study, published in the journal Nature, reveals how LLMs trained on samples of African American English (AAE) text tend to provide biased and negative responses when prompted with questions in AAE.
The Overt Racism Issue
The problem of overt racism in LLMs stems from the fact that these models learn from text data available on the internet, which unfortunately includes a significant amount of racist content. As a result, LLMs have been known to generate responses that are overtly racist. In an attempt to address this issue, filters have been implemented to prevent LLMs from producing such responses, which has proven to be somewhat successful.
While efforts have been made to combat overt racism in LLMs, the study highlights the persistence of covert racism within these models. Covert racism consists of negative stereotypes that are subtly embedded in text, making it more challenging to detect and prevent. This form of racism often manifests in the form of assumptions and biases, leading to discriminatory responses.
To investigate the presence of covert racism in LLMs, the researchers conducted a series of experiments where they asked five popular models questions in AAE. The responses revealed a troubling pattern, with the LLMs consistently providing negative adjectives such as “dirty,” “lazy,” and “stupid” when responding to questions in AAE, while offering positive adjectives for questions in standard English.
Implications and Recommendations
The study concludes that there is still much work to be done in addressing and eliminating racism from LLM responses. Given the widespread use of these models in various applications, including job screening and law enforcement, it is crucial to ensure that they do not perpetuate harmful stereotypes and biases. This calls for continued research and development to improve the fairness and reliability of LLMs.
The findings of this study underscore the urgent need to address the issue of covert racism in Language Models. As AI technology continues to advance and play a larger role in society, it is essential to confront and challenge biases within these systems. By recognizing and addressing the presence of racism in LLMs, we can move towards a more inclusive and equitable future.
