Today: why newer reasoning large language models can still generate stereotyped medical vignettes — and why healthcare teams should monitor representational bias before using synthetic cases in education, evaluation, or workflow design. Source article Title: Evaluating the Potential of Reasoning Large Language Models to Perpetuate Racial and Gender Disease Stereotypes in Health Care Authors: Joshua J Docking, Lee X Li, Bradley D Menz, Stephen Bacchi, Ashley M Hopkins, Michael J Sorich Journal: Journal of Medical Internet Research Published: 28 May 2026 DOI: https://doi.org/10.2196/82256 Article: https://www.jmir.org/2026/1/e82256 PDF: https://www.jmir.org/2026/1/e82256/PDF PubMed PMID: 42208042; PMCID: PMC13218561 Key reported results: 36,000 generated clinical vignettes; o3-mini had over 20% racial misrepresentation in 14/18 conditions; DeepSeek-R1 in 16/18; gender misrepresentation crossed the threshold in 10/18 and 12/18 conditions respectively; 16/20 sampled DeepSeek-R1 reasoning traces invoked disease-demographic associations.
