Can you trust AI answers? How to check their accuracy.

AI answers can be useful, but they can contain incorrect facts or made-up references. Before you use an answer, check its main claims against an independent source. Open that source and confirm it supports what the AI says. A confident explanation or a list of links is not enough to establish accuracy.

Can ChatGPT give you incorrect information?

Yes. ChatGPT and other generative AI tools can produce information that is wrong or misleading. The House of Commons Library’s guidance on working with AI describes this problem and recommends checking generated material carefully. You might hear these mistakes called “hallucinations”. An AI hallucination is incorrect or invented information presented as though it were factual. It might be a wrong date or a reference to a source that does not exist.

Start with one claim you can investigate; you don’t need to be an expert in everything.

How do you check whether an AI answer is accurate?

Choose one factual claim and compare it with an independent source that has a reason to know the answer.

Suppose you ask an AI tool for facts about a planet for a presentation. Instead of treating the whole response as either right or wrong, pick one sentence. A date, a measurement or the name of a mission gives you something specific to investigate.

Write that claim down in your own words. Then look for a source that has a reason to know the answer. For a space mission, that could be the agency running it. For a school’s term dates, it would be the school’s current calendar.

This is also a useful moment to ask whether the answer actually matches your question. A correct fact about a different mission won’t help your presentation.

Can you trust the sources an AI tool gives you?

Check each source yourself. A link with an official-looking title is only a starting point. Open it. Check that the page exists, that the organisation is the one you expected and that the page supports the claim you are checking.

If the answer links to a long report, use the report’s search feature to find the relevant words. Read the surrounding paragraph too. A sentence describing a possible future event means something different from a sentence confirming it has happened.

If you cannot find the supporting information, leave the claim out for now. Asking the same AI tool to reassure you is not independent evidence.

Why do dates matter when checking AI answers?

The date tells you whether information is current enough for your question. Some answers change with time. A tool’s features, a competition deadline or a subscription price may be different from what an older article describes.

Look for both the date on the source and the date of the event it discusses. If the page has been updated, check what changed. A recently updated page can still describe an event from years ago.

For your own notes, a short line is enough: “Checked against the organisation’s announcement on 2 November.” That gives you a way to trace the information later.

Try checking an AI answer together

With a parent or teacher, choose an age-appropriate AI tool you are permitted to use. Ask it about a topic you already know a little about. Avoid sharing personal details.

Choose one factual statement from its answer and make a note of it. Find an independent source, then explain whether that source confirms the statement, contradicts it or leaves you unsure. Keep the source link beside your note.

An uncertain result is still useful. It shows you where the evidence runs out. You can try a narrower question or ask someone with knowledge of the subject.

Decide what belongs in your work

Once you have checked the material, decide what belongs in your project. You might rewrite an explanation, remove a distracting detail or decide to use a different source altogether.

Parents can ask: “Which part did you check, and how?” It gives a young person room to explain their thinking without turning the conversation into a test of who knows the most facts.

The part worth practising is deciding what to use. AI offers an answer; you work out whether you have enough evidence to rely on it.
