Lateral reading: judging a claim by leaving the page

When you finish, you can quickly judge whether a website, claim or AI-cited source deserves your trust.

Don’t stay on the page

Many people judge a website by how it looks. Professional design, official-sounding names and confident text all feel trustworthy. But anyone can make a polished page. Fact-checkers use a different method called lateral reading. Instead of studying the page, they leave it and look for what others say about it.

Open a new tab. Search the name of the site or organization. Who runs it? Who funds it? What do independent sources say? Do they have a reputation for accuracy or for pushing an agenda? A minute of this often tells you more than ten minutes of reading the page.

Check the claim, not just the source

Take the specific claim and search for it. Do other independent, reliable sources report the same thing? If only one obscure site says it, be careful. If a claim is dramatic and no serious outlet mentions it, that is a warning sign.

Look for the original. News and social posts often repeat things from someone else. Trace the claim back: who first said it, and where? Many false stories grow from a real fact that was shortened, shifted or taken out of context.

Use AI as a helper, not a judge

AI can help with lateral reading by suggesting what to search: “What questions should I ask to judge the reliability of an organization called [name]?” It can list the type of evidence to look for. But it should not be the judge, since it may not know the organization, or may invent a reputation.

You can also ask the tool to explain how to verify a claim: “What are three ways I could check whether this claim is true?” Then do those checks yourself. Think of the tool as a research coach who points, while you walk.

A worked example from daily work

Adaeze, a shop owner in Enugu, finds a site that an AI answer cited for a claim about a business-grant program. The site looks official. She opens a new tab and searches the program’s name. The country’s government page, which she finds through a trusted route, shows no such program, and several local news outlets warn about a scam using that name.

She does not apply and warns her group. The AI’s answer would have led her toward a scam. Lateral reading took five minutes. Remember: when money, identity or safety is involved, leave the page and look sideways before you act.

Practice now

Pick a website you do not know, perhaps one an AI tool cited. Without reading its pages in depth, open new tabs and find out who runs it and what independent sources say about it. Write a three-line verdict.
Choose a surprising claim from your social feed. Trace it to the original source and note what, if anything, changed along the way.

Use any AI assistant you have. Do not paste private, client or patient information into it.
