Don't just read what AI tells you — open new tabs and check the claim against other sources.

The big idea
Lateral reading means: when AI says something, you don't keep reading AI — you open a new tab and search to see if anyone else says the same thing. Pros do this in seconds for any claim that matters.
Some examples
AI says 'studies show X.' You search 'X study' to find the actual study.
AI gives a date. You check it on Wikipedia or a news site.
AI quotes a person. You search the quote in quotes to see if it's real.
AI describes a law. You look up the actual statute on a .gov site.
Try it!
Next time AI tells you a fact, open one new tab and verify it before using it. Make this a 10-second habit.

What does lateral reading mean when used to check AI-generated information?
Sharing AI answers with friends to get their opinions
Opening new browser tabs to search for confirmation of what AI said
Copying AI text into a document for later review
Reading the AI's response multiple times to understand it better
AI tells you that 'scientific studies show chocolate improves memory.' What is the best next step?
Search for the actual study to see if it exists
Accept it because AI has access to lots of information
Ask the AI to list more studies like that one
Post it on social media to share with others
Why do professionals use lateral reading instead of just reading more carefully?
Because AI always tells the truth when you read closely
Because lateral reading is required by school rules
Because reading carefully takes too long
Because AI can generate convincing but false information
AI gives you a date for a historical event. What should you do?
Ignore the date and focus on other facts
Trust the AI since it has a large database
Check the date on Wikipedia or a news site
Memorize the date without checking
AI quotes a famous person saying something. How can you verify if the quote is real?
Ask the AI if the quote is real
Assume the quote is true because the person is famous
Share the quote and see if anyone corrects you
Search the quote in quotation marks to see if it appears elsewhere
The lesson recommends looking up laws on which type of website?
Social media platforms
Online forums
.com websites
.gov websites
What habit does the lesson suggest building?
Read every AI response three times before using it
Only verify AI facts that seem obviously wrong
Never use information from AI under any circumstances
When AI tells you a fact, open one new tab and verify it within 10 seconds
The lesson compares researchers to what type of worker?
Journalists who verify information before publishing
Copy-pasters who share information as-is
Translators who convert text between languages
Designers who create new content
When should you leave the AI tab and check information elsewhere?
When the information matters and you plan to use it
Never — AI tabs should stay open for reference
Only when the AI explicitly says it might be wrong
Only for science topics, not for general facts
A friend tells you they used AI to write a school report and everything checked out. What does 'checked out' likely mean?
They verified the facts using lateral reading
They asked the AI if the information was true
They copied the text without any errors
They read the AI response carefully
Why is opening a new tab better than just re-reading what AI wrote?
Because AI cannot be read twice
Because reading takes too much effort
Because AI might have made up information that looks real
Because new tabs load faster than refreshing
You want to verify if a law AI mentioned actually exists. Where should you look?
A government website that publishes actual laws
A social media discussion about the law
The same AI chatbot that mentioned the law
A popular blog that discusses laws
What makes lateral reading different from just being skeptical?
There is no difference between the two approaches
Being skeptical means not using AI at all
Lateral reading requires you to argue with AI
Lateral reading involves taking action to verify claims externally
If you search for 'study about X' and find nothing, what should you think?
Studies about X definitely don't exist
The study AI mentioned might not exist
The search engine is broken
You should search for a different topic
What is cross-checking in the context of AI fact-checking?
Copying information from one place to another
Comparing two AI chatbots to each other
Reading AI text and human text at the same time
Comparing what AI says to what other trusted sources say
