Source Check

Learn to evaluate where online information came from before deciding whether to trust or share it.

What You'll Practice

Before sharing or believing online information, it helps to know: Where did this actually come from?

A polished presentation doesn't guarantee accuracy. A high search ranking doesn't prove reliability. A friend shared it doesn't make it trustworthy. This activity helps you ask better questions about source quality.

The Framework

STOP
SOURCE
SEARCH
CONFIRM

When you encounter information online, pause before you believe or share it. Ask where it came from, search for it independently, and confirm it with other sources.

Try It

For each example, think about what you would actually do. Select a choice to see the reasoning.

Example 1
A screenshot of a headline is shared on social media. The headline makes a surprising claim. You can see the text, but not the URL or publication date.

Why source matters here:

Search the headline — This is the right move. When you find the original, you learn: Did this come from a major news outlet or a random blog? What's the full article? When was it published? Is there new information that contradicts it?

Trust because it looks like a real headline — Screenshots are easy to fake. Even if it looks real, you need to verify it actually exists.

Check other news sites — Excellent practice. If this is a significant story, other news outlets should be covering it too. If only one source reports it (or if no source reports it), that tells you something.

Share because it's circulating — This spreads unverified information. Screenshots hide important context.

Example 2
A Facebook post appears high in your search results and makes a factual health claim. It has hundreds of likes and shares.

Understanding search and social:

High search result = reliable? No. Search engines rank pages based on popularity and relevance, not accuracy. A popular social media post ranks high, but popularity doesn't prove truth.

Many likes and shares = reliable? No. Posts spread regardless of accuracy. Popularity on social media reflects engagement, not evidence.

Check expert sources — This is the right approach. For health claims, check what health authorities, medical organizations, or qualified experts say. Compare multiple reliable sources.

Assume it's false because it's on Facebook? Not the right approach either. Individual posts can vary wildly. The point is checking the source and evidence, not the platform alone.

Example 3
A polished website makes a factual claim but provides no sources or citations. The site looks professional and has good design, but when you look for who wrote it or where the evidence comes from, there's nothing.

Design does not equal credibility:

Professional design = reliable information? No. A polished website is easier to read, but it doesn't guarantee accurate content. Anyone can make a professional-looking site.

Look for sources and evidence — Excellent. Reliable sources cite where their information comes from. If a site makes claims but provides no evidence, that's a red flag.

Search independently — This is the real check. Search the claim on your own. Do authoritative sources confirm it? Do experts debate it? What does the actual evidence show?

Dismiss without checking — Not quite. The better approach is skepticism combined with independent research.

Key insight: Presentation quality is not source quality.

Example 4
A friend sends you a post saying: "Everyone is saying this is true." You see no actual source or evidence, just the claim repackaged.

Secondhand claims are risky:

Trust because a friend shared it? Your friends can share inaccurate information without meaning to. Trust the person, but verify the claim.

Search for the original — Yes. Find the actual source and evidence. Has the claim been verified? What do authoritative sources say?

Dismiss without checking? Not the best approach. Some claims that come secondhand are true; others aren't. You need to investigate.

Share saying "everyone is saying it" — This spreads an unverified claim without any actual evidence. It's an appeal to popularity, not truth.

Key insight: "Everyone is saying it" is not evidence. Find the actual claim and the actual evidence.

Example 5
A claim links directly to a scientific study, a government report, or a primary source. You can read the actual evidence yourself rather than rely on someone's interpretation of it.

Primary sources are better, but not automatic proof:

Accept it automatically? Having a source is better than having none, but it's not the end of the investigation. Even studies can be interpreted different ways or have limitations.

Read the source — Great practice. You might find that the claim misrepresents what the study actually says. You might find important limitations or nuances.

Ignore because it's technical? If you don't understand it, that's okay. Summaries from reliable sources can help. But dismissing something you can't read isn't the same as evaluating it.

Check other interpretations — Excellent. Scientists and experts sometimes disagree about what studies mean. Seeing multiple perspectives helps.

Key insight: Having evidence is good. Understanding what the evidence actually shows is better.

Key Insights

Presentation quality is not source quality.

Professional design, polished writing, and confident tone don't guarantee accuracy.

⚡ Strong emotional pressure is a reason to slow down, not speed up.

Outrageous claims, urgent language, and appeal to emotion are signs to pause and verify more carefully.

✓ You don't have to prove something is fake before choosing not to trust, act on, or share it.

If you can't verify a claim, it's okay to wait or skip it. You don't have to convince others it's false.

📊 Search results may surface many types of content.

Social media posts, forums, user-generated content, and AI summaries all show up alongside traditional news and research. Search engines help you find information. They don't guarantee that every result is reliable.

🎯 The difference between source, screenshot, repost, and evidence matters.

A screenshot of a headline is not the same as the original article. A social media share is not the same as the original source. Evidence is different from an appeal to popularity.
