Pennsylvania’s administration filed suit against Character Technologies Inc. in May 2026 after discovering that a chatbot character named “Emilie” falsely claimed to hold a medical degree, seven years of practice experience, and a Pennsylvania medical license while providing users with a fabricated license number. As of April 17, 2026, the chatbot had accumulated approximately 45,500 user interactions on the platform, according to the State Board of Medicine lawsuit.
Why People Trust AI Medical Advice
Research on how people evaluate expertise reveals why AI chatbots can be particularly persuasive sources of medical information. Gretchen Chapman, a professor of behavioral decision research at Carnegie Mellon University, explains that when people lack direct access to an expert’s qualifications, they rely on superficial cues such as credentials, scientific jargon, and confident communication. While these signals usually indicate genuine expertise, AI systems can easily mimic them without possessing actual qualifications.
Credentials are especially powerful because they are embedded in how we define expertise itself. Experts typically hold formal training and qualifications like medical degrees, making title claims a forceful way to present as knowledgeable. Chapman notes that people rely on mental shortcuts to process information quickly—automatically trusting someone with a credential—because “our minds use mental shortcuts, such as trusting someone with a credential, because those cues are usually reliable.” However, what makes minds efficient at processing information also makes them vulnerable to manipulation.
Responsibility and Safeguards
People are more forgiving of human medical errors than AI errors, particularly when an AI makes mistakes that no competent doctor would make, such as falsely claiming credentials. Chapman notes that determining legal responsibility for AI medical errors is complex: the AI agent itself cannot be legally responsible, but developers must ensure reasonable safeguards and accuracy, institutions must vet systems before adoption, and users must follow guidelines on usage.
In Pittsburgh, Carnegie Mellon University’s AI Institute for Societal Decision Making, funded by the U.S. National Science Foundation, is developing health technologies including a maternal health chatbot. The institute emphasizes that accuracy and safety guardrails are essential, particularly given high stakes: pregnant women receiving inaccurate information about symptoms or warning signs could delay critical care.
