A new research paper explores demographic leakage in de-identified résumés, finding that even after removing explicit demographic fields like language, non-language prose still allows for significant inference of ethnocultural background. The study tested nine open-weight language models and revealed that models diverge in their ability to detect these subtle cues, highlighting the importance of cue salience in bias evaluations. Furthermore, the paper demonstrates that the methodology used for LLM-as-a-judge evaluations, such as whether ties are permitted, heavily influences outcomes and can introduce biases independent of the résumé content itself.
