AI Hallucinations: When Chatbots Confidently Lie

An AI hallucination is when an AI makes something up and presents it as true — with total confidence. The AI is not lying on purpose. It just predicts what words sound right, and sometimes those words describe things that do not exist: fake quotes, wrong facts, made-up laws, fictional people. It has no real understanding of truth. It only knows patterns in text. So it can produce a beautifully written answer that is completely wrong.

Example: A lawyer used ChatGPT to find legal cases to cite in court. The AI invented several cases that never existed — complete with fake judges, fake dates, and fake rulings. The lawyer submitted them anyway. The judge caught it. The lawyer faced serious consequences.
