Linguistic Bias in ChatGPT: Dialect Discrimination
Read Full Article: Linguistic Bias in ChatGPT: Dialect Discrimination
ChatGPT exhibits linguistic biases that reinforce dialect discrimination by favoring Standard American English over non-"standard" varieties like Indian, Nigerian, and African-American English. Despite being used globally, the model's responses often default to American conventions, frustrating non-American users and perpetuating stereotypes and demeaning content. Studies show that ChatGPT's responses to non-"standard" varieties are rated worse in terms of stereotyping, comprehension, and naturalness compared to "standard" varieties. These biases can exacerbate existing inequalities and power dynamics, making it harder for speakers of non-"standard" English to effectively use AI tools. This matters because as AI becomes more integrated into daily life, it risks reinforcing societal biases against minoritized language communities.

Virtual Personas for LLMs via Anthology Backstories
Read Full Article: Virtual Personas for LLMs via Anthology Backstories
Anthology is a novel method developed to condition large language models (LLMs) to create representative, consistent, and diverse virtual personas by using detailed backstories that reflect individual values and experiences. By employing richly detailed life narratives as conditioning contexts, Anthology enables LLMs to simulate individual human samples with greater fidelity, capturing personal identity markers such as demographic traits and cultural backgrounds. This approach addresses limitations of previous methods that relied on broad demographic prompts, which often resulted in stereotypical portrayals and lacked the ability to provide important statistical metrics. Anthology's effectiveness is demonstrated through its superior performance in approximating human responses in Pew Research Center surveys, using metrics like the Wasserstein distance and Frobenius norm. The method presents a scalable and potentially ethical alternative to traditional human surveys, though it also highlights considerations around bias and privacy. Future directions include expanding the diversity of backstories and exploring free-form response generation to enhance persona simulations. This matters because it offers a new way to conduct user research and social science applications, potentially transforming how data is gathered and analyzed while considering ethical implications.
