Why this is worth taking seriously
More than 1 in 5 adults now ask AI chatbots health questions directly, and tens of millions of people consult ChatGPT for health information every day. Current research paints a clear picture of where this goes wrong. People assume a confident, detailed AI answer is more likely to be accurate than a short one. Research has found the opposite is often true: AI chatbots can sound completely certain while being wrong, including inventing citations that do not exist.

Frequently asked questions
Can I trust an AI chatbot for medical advice?
Treat it as a starting point for general information, not a diagnosis or a substitute for a professional, especially for anything urgent or serious.
What should I do if I think I have a medical emergency?
Contact emergency services or NHS 111 directly. Do not rely on an AI chatbot to assess how serious a symptom is.
Are AI citations for medical claims reliable?
Not reliably. Studies have found a significant proportion of AI-generated citations are inaccurate or fabricated, always check a source independently.
