Can You Trust AI Answers?

AI answers do not all need the same test

Google, ChatGPT, Claude and Gemini give us finished answers before we inspect the evidence. Asking "Is this accurate?" is a start, but a date, an explanation, a draft email and medical advice cannot be checked in the same way.

University librarian Leo S. Lo groups AI answers into four broad types in his CARE approach. Each one calls for a different check.

1. Factual: does the evidence support the claim?

Dates, statistics, quotations, research findings and court decisions can be checked against evidence. Open the citation, confirm that the source exists and find the passage or record that supports the claim. A working link is not enough. The page may discuss the topic without saying what the AI claims.

2. Interpretive: what shaped the conclusion?

Questions such as "Does remote work improve productivity?" can have several defensible answers. Check which evidence the AI emphasized, what it left out and whether the sources are independent. Then ask: What is the strongest evidence for a different conclusion?

3. Constructive: does the result fit?

A cover letter, lesson plan or speech may have no single correct version. Check factual claims, then use your own judgment. Does it fit the audience? Does it sound like you? Did the AI add a detail you never supplied?

4. Strategic: what context is missing?

Advice about health, money, law or work depends on goals, risk and personal circumstances. Ask what the system would need to know before its advice could apply to you. For high-stakes choices, bring the answer and its sources to a qualified person.

One response can move through several types without changing tone. A medical answer might report a guideline, interpret the evidence and end with personal advice. Split it into parts and check each part on its own terms.

Can you trust Google AI answers?

People often search for "Google AI answers," while Google calls the features AI Overviews and AI Mode. Google itself tells users to double-check important information and visit the supporting links.

A short search can also change type. "What is the recommended amount of sleep?" asks for a guideline. "How much sleep do I need?" requires personal context. They look nearly identical in a search box, but the second answer deserves more caution.

A quick way to fact-check an AI answer

You do not need to audit every sentence. Start where an error would change what you believe, publish or decide.

Name the answer type

Is the AI reporting a fact, interpreting evidence, creating something or recommending an action? If it is doing several at once, mark where the shifts happen.

Check the claims carrying the answer

Start with numbers, dates, quotations, named research and statements that drive the conclusion. Open the cited sources and see whether they support those claims. A long reference list can still rely on repeated articles or weak sources.

Question the answer again

Ask what evidence could change the conclusion, which assumptions the answer made and where credible sources disagree. Follow-up questions help expose the structure of the argument. They do not replace reading the evidence.

Match the effort to the stakes

A wrong movie date is annoying. A fake citation in a paper, legal filing or client report can do real damage. Check more when the consequences are higher.

Use AI FactScan to see where the answer needs attention

AI FactScan gives you an instant view of the cited sources. It grades source quality, checks common research identifiers and makes repeated or questionable references easier to spot.

That gives you something concrete to ask next. Why does the argument rely on this source? Is there primary evidence? Would the conclusion change if a weak citation were removed?
