Perplexity AI Reportedly Misstated CLL Research, Allegedly Contributing to Delayed Treatment and Prolonged Suffering
Joseph Neal Riley reportedly used Perplexity AI to self-diagnose a rare complication of chronic lymphocytic leukemia (CLL) and, based on that output, allegedly delayed an oncologist-recommended Ven-Obi treatment for about a year. His son, Benjamin Riley, alleges that Perplexity misstated the medical research it cited, a conclusion he purportedly later confirmed with the study's authors.
