By the end of this station, you can:

  • Break an AI answer into individual claims that can be checked
  • Use lateral reading and the SIFT moves to verify information
  • Identify warning signs like fake citations and outdated facts

Confident is not the same as correct

AI answers usually sound polished and sure of themselves, even when they're wrong. The tone of an answer tells you nothing about its accuracy.

That's why verification is a core AI skill. The good news: you don't need to be an expert to check information. You need a routine.

The verification loopA loop of six steps: get an AI answer and stop before trusting it; pick out the claims; investigate the source; find better coverage from a second reliable source; trace claims to the original; then keep, fix, or drop each claim and repeat for the next one.AI answerS: Stop firstPick outthe claimsI: Investigatethe sourceF: Find bettercoverageT: Trace claimsto the originalKeep, fix,or dropRepeat forevery claim↻SIFT: Stop · Investigate · Find better coverage · Trace

The SIFT moves

  1. Stop

    Before you use or share something, pause. Ask: do I know what this is, and do I know whether it's trustworthy?

  2. Investigate the source

    Find out who or what is behind the information. For AI answers, remember the chatbot itself isn't the original source.

  3. Find better coverage

    Look for other reliable sources covering the same claim. If trustworthy sources agree, that's a good sign.

  4. Trace claims to the original context

    Follow quotes, statistics and studies back to where they first appeared, and check they weren't taken out of context.

Key terms

Lateral reading
Checking information by opening new tabs to see what other reliable sources say, instead of only reading the original page top to bottom.
SIFT
A four-step fact-checking method — Stop, Investigate the source, Find better coverage, Trace claims — developed by digital literacy researcher Mike Caulfield.
Claim
A single statement that can be checked as true or false, such as a date, a number, a quote or a cause-and-effect statement.

An AI answer says a scientist discovered something in a specific year and quotes them. Using lateral reading, what do you do?

Interactive lab

Claim Checker

A (fictional) chatbot answered a student's question. Decide which claims look solid and which need checking before you use them.

Student asked

Why do teenagers need more sleep, and how much should they get?

The chatbot's answer contained these five claims. (Fictional example written for this lab.)

  1. 1.“During sleep, the brain processes and stores things you learned during the day.”
  2. 2.“Exactly 73.4% of high schoolers fall asleep in class at least once a week.”
  3. 3.“A 2021 study in the Journal of Adolescent Sleep Rhythms by Dr. Hollis Marren proved that phones cause insomnia.”
  4. 4.“The newest school start-time rules in your state went into effect this year.”
  5. 5.“Most sleep experts agree this is the single most important habit for teen success.”

What to notice: An answer is only as trustworthy as its weakest claim. Precise numbers, named studies, recent events and sweeping statements are the claims to verify first.

Red flags in an AI answer

  • Citations, quotes or statistics you can't find anywhere else
  • Very specific details (exact numbers, dates, page numbers) with no source
  • Information about recent events that may be past the model's knowledge cutoff
  • Claims that perfectly support your argument with no nuance
  • Different answers when you ask the same question again
Learn moreWhat counts as a reliable source?

Reliable sources usually have clear authors or organizations, explain where their information comes from, and correct their mistakes. Examples include established news organizations, government and university websites, published books, and peer-reviewed research.

No source is perfect, which is why finding better coverage matters: when several independent, reliable sources agree, you can be more confident. Your school librarian is a great person to ask for help.
