AI incidents

Reports of AI-related harm and adverse experiences affecting people’s safety, wellbeing, rights and livelihoods. Explore what happened and the evidence available.

NOPE’s core concern is when AI communicates with a person, acts on their behalf, or depicts or impersonates them. The tracker is wider: it also records consequential decisions and claims about people. Each account is reviewed for publication; claims may remain uncorroborated or disputed.

Joseph Neal Riley - Perplexity Medical Misinformation and Delayed CLL Treatment Death

Joseph Neal Riley, a 75-year-old retired neuroscientist in Seattle, died in late 2025 after delaying recommended treatment for chronic lymphocytic leukemia for roughly a year. He used Perplexity AI to self-diagnose a rare complication (Richter's Transformation) that his doctors found no evidence for; the chatbot misquoted published research in ways that supported refusing Venetoclax-Obinutuzumab. His son, AI critic Benjamin Riley, documented the case in a first-person Substack essay and it was later featured by the New York Times.

Cases may have several effects and sources. Mixed accounts qualify when they include a reported harm or adverse experience. People are counted within individual cases where sources support a number; we do not publish a collection-wide total of distinct people.

A source’s existence, the experience it reports and AI’s causal role are separate questions. A lawsuit records allegations unless a subsequent finding establishes them.
