🧠 Step 4: Evaluate Source Credibility

From the “52 Actions to Master Knowledge Production” Series
By Greg K. Campbell | Academic Coach & Learning Designer

In the age of endless information, knowing what to trust is as essential as knowing how to think.

Whether you're researching for an academic project, writing a blog post, or just trying to form an informed opinion, one of the most powerful skills you can develop is the ability to evaluate source credibility. It’s the difference between knowledge built on solid ground and conclusions built on sand.

Step 4 of our 52 Actions series is about training your internal “BS detector”—the ability to look at a source and ask, “Is this reliable, relevant, and responsible?”

📚 Why It Matters

In a world of viral tweets, AI-generated content, and paywalled research, it’s easy to fall into one of two traps:

1. Assuming everything online is equally valid, or

2. Only trusting academic or elite sources, even when they might be out of date or not culturally grounded.

The goal here isn’t to become cynical. It’s to become critically curious—someone who can explore ideas while staying grounded in evidence and ethics.

🔍 What to Look For

To evaluate a source’s credibility, get in the habit of asking:

1. Who is the author, and what are their credentials?

• Are they an expert in the field?

• Do they have lived experience with the topic?

2. Where is it published?

• Is it peer-reviewed? Published in a reputable outlet?

• If it’s a blog, newsletter, or social media post—does it cite sources or build a strong case?

3. When was it written?

• Is the information still accurate and relevant today?

• Have there been new developments in the field?

4. What’s the purpose?

• Is the goal to inform, persuade, entertain, or sell something?

• Does the content show signs of bias or manipulation?

5. How is evidence used?

• Are claims supported with data, citations, or clear reasoning?

• Are counterarguments addressed—or ignored?

🧪 Quick Exercise: Source Comparison

Let’s say you're researching the effects of AI on education. You find:

• A 2020 Forbes article titled, “AI Is Changing the Classroom.”

• A peer-reviewed journal article from 2018 in Computers & Education.

• A TikTok by a high school teacher discussing their experience using ChatGPT with students.

Which is credible? Trick question—all three can be, depending on how you use them. The real power comes from triangulating them:

• The article offers public perception.

• The journal provides in-depth research.

• The TikTok gives lived experience and immediacy.

Evaluating credibility doesn’t mean dismissing certain formats. It means understanding the strengths and limits of each.

✨ Build the Habit

To turn this into a repeatable skill:

• Bookmark a few fact-checking tools (like Snopes or Media Bias/Fact Check).

• Use a credibility checklist for any source you cite.

• Practice with a peer—share 3 sources and assess them together.

• Write down your reasoning, not just your judgment.

Over time, you’ll sharpen your instincts. You’ll notice red flags faster and trust your own evaluation process more.
