AI can sound confident and still be wrong. That is called a hallucination: an answer that sounds right but is wrong, unsupported, outdated, or made up. Use this five-step check. What claim is being made? Is there a trusted source? Are names, dates, and numbers correct? Could a mistake cause harm or cost money? Should a human expert review it? Remember: confidence is not correctness. Remember: protect private information, and verify important AI answers with trusted sources.
