    What are hallucinations?

    ~15s
    AI "hallucinations" are when a chatbot confidently states incorrect information — fake quotes, made-up statistics, or non-existent sources.
    2

    Why it happens

    ~15s
    AI predicts the most likely next word based on patterns, not truth. It doesn't "know" facts — it generates plausible-sounding text.
    3

    Red flags to watch for

    ~15s
    Be skeptical of specific numbers, quotes, URLs, academic citations, and recent events. These are common hallucination areas.

    How to verify

    ~15s
    Cross-reference important claims with reliable sources. Ask the AI to provide its sources, then check if those sources actually exist.
    5

    Use grounded AI when possible

    ~15s
    Gemini and Bing Chat connect to the web for real-time info. ChatGPT with browsing enabled can also search for current data.
