Never judge information by how the page looks — check who is behind it, because the best way to learn about a website is to leave it.
🐙The Tree Octopus Test (2006)
24 out of 25 believed in an animal that doesn't exist.
Researchers gave 25 seventh graders — picked as their schools' best online readers — a website about the endangered "Pacific Northwest tree octopus," Octopus paxarbolis, a shy creature that supposedly climbs into misty treetops to hide from the sasquatch. Photos, a FAQ, a "Save the Tree Octopus" campaign. All fake — a joke site built in 1998 by a humor writer using the name Lyle Zapato.
Twenty-four called it trustworthy and recommended it to another class. When researcher Donald Leu revealed the truth, some refused to believe him. They weren't careless — they judged the page by how it looked instead of asking who was behind it.

🧭SIFT — the 4 moves the pros use
SStopBefore you believe or share, pause. Notice how the post makes you feel — strong emotion is a signal to slow down.
IInvestigate the sourceRead laterally. Who is behind this, and do they actually know what they're talking about?
FFind better coverageSearch the claim itself. Have trusted outlets or fact-checkers already covered it?
TTrace to the originalChase down the actual study, the full video, the firsthand account — the primary source. Clips and screenshots lose the truth in the cropping.
⏱️ Digital literacy expert Mike Caulfield bundled the professionals' habits into these four moves, and the whole routine takes about thirty seconds. That's media literacy: questioning and evaluating the messages you see instead of just absorbing them.
🔍Reading Down vs. Reading Across
⬇️VERTICAL READING
Staying putYou scroll down the same page, admiring the logos, the links, and the official-sounding language.
The trapA slick "About Us" page can claim anything — the site wrote it about itself.
🎓 What the historians and Stanford students did — and they were fooled again and again.
➡️LATERAL READING
Leaving fastYou open new tabs and search what independent sites, news outlets, and encyclopedias say about the source.
Why it worksThe site controls its own page — but it can't fake the neighbors' opinion.
✅ In Stanford's 2017 study, 10 professional fact-checkers left the site almost immediately — and were faster and far more accurate.
🏁Why Lies Outrun the Truth
MIT, 2018 — the largest study ever done on how news travels online: ≈126,000 stories on Twitter over eleven years, each checked by independent fact-checking organizations. It wasn't bots — automated accounts were filtered out. The best explanation is novelty: false stories are stranger than reality, and surprising things feel irresistible to share.
🔁The Engagement Loop
That's why clickbait works. You Won't BELIEVE What This Coach Did Before the Big Game! opens a curiosity gap — a secret your brain itches to close. Every click teaches the algorithm to show the post to more people, and suddenly misinformation is viral. A plain headline like "City Council Approves New Bike Lanes on Main Street" is boring on purpose: it just tells you the news.
⚖️Misinformation vs. Disinformation
🤷MISINFORMATION
False — by accidentShared by people who believe it's true.
☎️ A game of telephone: the message got garbled at player two, and now the whole playground confidently repeats the wrong sentence.
😈DISINFORMATION
False — on purposeBuilt by someone who wants to trick you.
🃏 A counterfeit trading card printed to fool collectors — the fake didn't happen by accident; someone designed it to deceive.
🛑 Either way — honest mistake or deliberate trick — it stops with whoever checks.
👁️When Seeing Isn't Believing
The newest challenge: deepfakes. AI-generated video or audio can make a real person seem to say things they never said. Researchers at the University of Washington built a website where visitors guess which of two faces is real and which was invented by AI — most people miss more often than they expect.
🔑Key Terms
🤷MisinformationFalse or misleading information that spreads around, even when the people sharing it believe it's true.
😈DisinformationFalse information someone creates and spreads on purpose in order to trick people.
🕵️Lateral readingChecking a source by leaving its page and searching what other independent sites say about it.
🎣ClickbaitA headline or thumbnail designed to tease and exaggerate so you can't resist clicking.
🎛️AlgorithmComputer instructions that decide which posts to show you — usually favoring whatever gets the most clicks and shares.
🎭DeepfakeA video or audio clip made with AI that shows a real person saying or doing something they never did.
📄Primary sourceThe original, firsthand version: the actual study, the full video, or an eyewitness account.
🌍Where This Shows Up in Real Life
📰 Newsroom fact-checking desks
Journalists at wire services like the Associated Press and Reuters use the exact skills on this poster — reverse image searches and tracing to the original — to debunk recycled disaster photos within hours of every major storm.
🏛️ College & university libraries
Librarians at hundreds of universities now teach the SIFT method to incoming freshmen, because professors found that even straight-A students were judging sources by their looks instead of reading laterally.
🐙 Still fooling people since 1998In the University of Connecticut study, some seventh graders kept insisting the tree octopus was real even after researchers told them the site was a hoax.
💸 Ads in disguiseIn a Stanford study of nearly 7,800 students, more than 80% of middle schoolers saw an article labeled "sponsored content" — a paid ad — and thought it was a real news story.
⭐
False stories outrun true ones because they're more surprising — and because engagement algorithms reward clicks and shares, not accuracy.
The professionals' secret is lateral reading: the best way to learn about a website is to leave it and see what other independent sources say.
SIFT — Stop, Investigate the source, Find better coverage, Trace to the original — takes about thirty seconds and beats hours of staring at a slick-looking page.
24 out of 25 students believed in a tree octopus. Be the twenty-fifth.
