TL;DR: This position paper argues that AI research must move beyond rigid racial taxonomies, which reinforce essentialist views and overlook the complexity of racial discrimination.
Abstract: This position paper critiques the reliance on rigid racial taxonomies in machine learning, exposing their U.S.-centric nature and lack of global applicability—particularly in Europe, where race categories are not commonly used. These classifications oversimplify racial identity, erasing the experiences of mixed-race individuals and reinforcing outdated essentialist views that contradict the social construction of race. We suggest research agendas in machine learning that move beyond categorical variables to better address discrimination and social inequality.
Lay Summary: Many machine learning tools and bias-detection methods still rely on fixed race groups—White, Black, Asian—borrowed from U.S. census labels. This position paper argues that such broad categories flatten complex identities, erase mixed-race experiences, and treat race as if it were a biological fact, which risks embedding stereotypes into everything from hiring software to image processing.
Instead of using those rigid labels, the paper recommends dropping categorical race variables and focusing on the real traits that drive discrimination in each context—skin tone, facial features, spoken language, nationality, and other locally relevant characteristics. Because the attributes that matter vary by setting, it calls for a participatory process: working directly with affected communities and domain experts to choose the right mix of traits for each application.
By shifting away from simplistic race labels toward flexible, multi-dimensional assessments, discrimination can be more accurately detected and mitigated. This move promises models that are both more equitable and more attuned to the rich diversity of human identities.
