Why AI Makes Mistakes and How to Check Its Answers

AI sometimes states something false in a very confident voice. This is often called a hallucination. It is not lying. It is guessing what sounds right. A few quick checks will protect you.

Step by step

  1. Watch for exact details. Names, dates, quotes, phone numbers, web addresses and statistics are where mistakes hide.
  2. Ask for its sources, then verify them. Ask where the information comes from. If it names a source, look it up yourself. Some invented sources look real.
  3. Compare with a second source. Search the key fact on a trusted site such as a government, hospital or major news website.
  4. Ask it to double-check. Try are you sure? and please re-read your answer and list anything uncertain.
  5. Raise your guard for big decisions. For health, taxes, legal and large purchases, use AI to prepare questions, then ask a professional.

Good to know. Think of AI as a very quick, very well-read assistant who sometimes gets things mixed up.
