You find a health article making a surprising claim about a supplement. To evaluate its credibility, which strategy would a media literacy expert most recommend?
ARead the article very carefully from top to bottom to find logical inconsistencies
BCheck that the website has a professional design and a clear 'About' page
COpen new browser tabs and search for what fact-checkers and other reputable sources say about the site and the claim
DFind multiple other websites that make the same claim to confirm it
This is lateral reading — rather than going deep into the source itself, you immediately leave it and search for what other sources say about it. Fact-checkers and academic databases have already assessed thousands of news outlets and claims; a 30-second search often provides more signal than 10 minutes of careful reading within the original. Professional design (Option B) is trivially fakeable. Multiple sites repeating the claim (Option D) can simply mean misinformation has replicated — it does not confirm the claim.
Question 2 Multiple Choice
You search a controversial claim and find 12 different websites all making the same assertion. Which question is most critical for evaluating whether this counts as strong corroboration?
AHow recently were the 12 sites updated?
BAre the 12 sites using .org or .edu domains?
CAre the 12 sites independently verifying the claim from distinct primary sources, or are they all citing each other or a single originating report?
DDo the 12 sites have similar professional visual designs?
Misinformation replicates — one false claim published on one site can be copied or paraphrased across dozens of sites within hours. Finding the 'same' claim on 12 sites provides strong corroboration ONLY if those sites independently verified the claim through separate primary sources with different editorial teams. If all 12 trace back to the same originating report, you have one data point repeated 12 times, not 12 independent data points. Domain extension (Option B) is not a reliable quality signal — anyone can register a .org.
Question 3 True / False
A website with a professional design, a clear 'About' page, and SSL security (the padlock icon) is a reliable source of factual information.
TTrue
FFalse
Answer: False
Design professionalism and technical security certificates say nothing about the accuracy of content. SSL certificates verify that data is transmitted securely — not that the information is true. Professional designs are inexpensive to create, and many disinformation operations invest heavily in visual credibility. A polished website can still contain deliberate misinformation, poorly reviewed content, or selective reporting designed to mislead while remaining technically accurate.
Question 4 True / False
When evaluating a source, reading deeply within the source itself is generally less reliable than lateral reading because credibility assessment experts consistently use the lateral approach.
TTrue
FFalse
Answer: True
This seems counterintuitive — we naturally want to evaluate something by examining it closely. But disinformation sources are often internally consistent and well-written; you cannot detect the problem by careful reading within them. Lateral reading (immediately opening new tabs to search what others say about the source) consistently outperforms internal reading because external sources — fact-checkers, watchdog organizations, investigative journalists — have already done the hard credibility work and their assessments are available in seconds.
Question 5 Short Answer
Why isn't it sufficient to check that multiple websites agree on a claim when evaluating its credibility online?
Think about your answer, then reveal below.
Model answer: Misinformation replicates faster than corrections. A single false claim, once published, can be copied, paraphrased, or reported as fact across dozens of websites within hours — especially on social media platforms that reward engagement over accuracy. When you find the 'same' claim on many sites, the critical question is whether those sites verified the claim independently from separate primary sources, or whether they all trace back to the same original report. Independent corroboration from distinct editorial teams means the claim was verified multiple times; repetition from a single source is one claim amplified, not multiple confirmations.
The practical test is to trace the claim: click through to the sources cited by the multiple sites and ask whether they all link back to the same originating article or whether they cite different primary evidence. Quantity of agreement is not the same as quality of evidence when the agreement is non-independent. What creates genuine evidential weight is independent verification — journalists at different organizations with different sources reaching the same conclusion through separate investigative processes.
