Disability Bias in AI

Disability is not one demographic variable. Blindness, deafness, chronic illness, mobility impairment, neurodivergence and speech disability can affect different interactions, and people within each group have varied preferences and support needs. Bias can arise through inaccessible interfaces, proxy features, missing training examples, or model outputs that associate disability with lower competence. It can also occur when an automated assessment treats one communication style as the only valid way to show ability. A 2024 Archives of Physical Medicine and Rehabilitation study tested ChatGPT and Gemini with generated descriptions of people, patients and athletes. It found that the systems underestimated disability in their generated sample and, in language analysis, described disabled people with fewer favorable qualities and more limitations. The study was an observational prompt experiment using 2023 versions; it does not establish how every current model behaves or how disabled people experience every deployment. A 2025 EMNLP paper introduced AccessEval, testing 21 open and closed models across six real-world domains and nine disability types with paired neutral and disability-aware queries. The authors reported more negative tone, higher factual error and greater stereotyping in disability-aware responses, with variation by domain and disability type; hearing, speech and mobility contexts were especially affected in their benchmark. A separate 2024 ASSETS interview study spoke with 30 people with disabilities about real-life chatbot use and needs. These studies show evidence of risks as well as use cases, but neither justifies broad conclusions about all disabled users or all AI. U.S. employers must also comply with the ADA when using software in hiring and employment; automation does not remove accommodation obligations.
