Check AI answers: errors, hallucinations and disinformation

AI can confidently invent facts. Use this simple method to check before sharing.

Goal

Spot questionable answers and use a four-step checking routine.

Generative AI produces language based on learned patterns. Fluent wording does not establish that a claim is true: an assistant can invent a quotation, statistic, law or reference while sounding convincing. This is often called a hallucination.

When to be especially careful

  • Numbers, statistics, dates and prices.
  • Laws, regulations and administrative processes, which vary between countries.
  • Quotations and sources with titles and links.
  • Health, money and legal questions, where mistakes can have serious consequences.
  • Recent developments: AI may not have current information.

The four-step routine

  1. Ask for sources — then open them. A source that does not exist is a warning sign.
  2. Cross-check — verify key information using reliable original sources, official institutions or reputable reporting.
  3. Question confidence — “Which parts of your answer are you least sure about?” Treat stated confidence as a prompt for further checking, not proof.
  4. Apply your expertise — if something does not fit your country or profession, investigate it before relying on it.
Review your previous answer. List each factual claim — number, date, name or law — and explain how I can check it against an original source. Clearly flag uncertainty and missing evidence.

AI and disinformation

AI also makes it easier to create fabricated text, images and voices. Before forwarding a shocking video or an “exclusive” WhatsApp audio, check who first published it and whether reliable outlets corroborate it. Verification is a professional habit.

Golden rule: share only information you have checked and can take responsibility for.

Today's challenge

Ask AI a factual question about your country, such as a recent statistic. Apply the four-step routine and note what was correct, approximate or wrong.
