How do you know if a source is trustworthy?

💭 How to Think About This

You read something online: "Scientists discover chocolate cures cancer!" Should you believe it? WHO said it? WHEN? WHERE was it published? Not all sources are equal - and learning to evaluate them is crucial in our information-overloaded world!

🔒 Start writing to unlock hints

WHO: Author credentials? Expert in this field?

WHAT: Type of source? News, opinion, satire, ad?

WHEN: Recent or outdated?

WHERE: Published where? Reputable outlet?

WHY: Purpose? Inform, persuade, sell, entertain?

TRUSTWORTHY sources typically:

• Cite their sources (footnotes, links, references)

• Have named, qualified authors

• Separate news from opinion clearly

• Correct errors transparently

• Use measured language (not sensational)

• Published by established organizations

BE SKEPTICAL when you see:

• No author listed (or author has no credentials)

• Sensational headlines ("SHOCKING!", "You won't believe...")

• No dates or citations

• Many ads or sponsored content

• URL designed to LOOK like reputable site (ABCnews.com.co)

• Only one source making this claim

DON'T just read the article! LATERAL READING = leave the site and search for:

(1) Who is the author?

(2) What do other sources say about this claim?

(3) What's the original source?

Fact-checkers do this constantly!

Evaluating sources means checking WHO said it, WHERE, WHEN, and WHY before believing!

The CRAAP Test:

Currency: Is it up-to-date?

Relevance: Does it answer your question?

Authority: Who's the author? Qualified?

Accuracy: Can you verify it? Sources cited?

Purpose: Inform, persuade, sell, or entertain?

Quick checks:

1. About page: Who runs this site?

2. Contact info: Can you reach them?

3. Other coverage: Do reliable sources report this?

4. Original source: Is this secondhand? Find the original!

5. Reverse image search: For photos - are they real/recent?

Hierarchy of reliability:

MOST reliable: Peer-reviewed research, expert consensus, primary sources

MODERATE: Established news organizations, verified reports

LEAST reliable: Social media posts, unknown websites, viral content

Golden rule: Extraordinary claims require extraordinary evidence!

🧠 Thinking habits this builds:

  • Checking dates on articles
  • Looking for citations
  • Cross-referencing claims

How to reinforce: "Great question! You're checking the source before believing - that's exactly what smart readers do."

🔄 When ideas are still forming:

Children might think anything "official looking" is true. Help them see that websites can be designed to look credible while being unreliable.

Helpful response: "A fancy website doesn't mean it's trustworthy. Let's look at WHO is behind it."

🔬 If you want to go deeper:

  • Compare coverage of the same story across different sources
  • Find a claim and trace it back to its original source
  • Explore the CRAAP test together

Key concepts (for adults): Source evaluation, CRAAP test, lateral reading, primary vs secondary sources, credibility markers.
