This audio may be AI-generated. Always verify important AI answers with trusted sources. World 3 is about checking AI answers. AI can sound confident and still be wrong. That is called a hallucination. A hallucination is when AI gives an answer that sounds correct but is wrong, unsupported, outdated, or made up. The safety phrase for this world is: confidence is not correctness. Use this verification checklist. One: identify the claim. Two: check a trusted source. Three: verify names, dates, and numbers. Four: ask whether a mistake could cause harm. Five: get human expert review for high-stakes topics. Here is a claim: Claude is always correct if you write a good prompt. That claim is wrong. A better prompt improves the answer, but it does not guarantee correctness. World 3 teaches a powerful habit: before you trust the answer, check the source.
