Source credibility checks

Evaluate whether a source is credible by checking the author, date, purpose, and evidence, and compare a reliable source to an unreliable one.

Not everything written down is trustworthy. Before you use a source in research, run four quick checks: WHO wrote it, an expert or anyone at all? WHEN was it written, recent enough to be accurate, especially for fast-changing topics? WHY was it written, to inform you honestly, or to sell you something or convince you of an opinion? WHAT evidence backs it up, real facts and data, or just claims?

A reliable source usually names its author and their expertise, is reasonably current, aims to inform rather than persuade or sell, and backs up claims with real evidence. An unreliable source might be anonymous, out of date, clearly trying to sell something, or full of claims with no evidence at all.

📋 For the teacher
Teach it (10–15 min):
  • Practice on something you already know is unreliable, an obvious ad or a joke website, first, so the checks feel low-stakes before applying them to real research.
  • Ask "why was this written?" as the single most revealing question -- purpose reveals bias fast.
  • It is fine for a source to have a purpose, persuasion or selling, and still contain some true facts -- the point is to notice the purpose, not reject everything with an agenda.
  • Model checking a source together on a device, narrating your own thought process out loud.
Talk about it:
  • What is the least trustworthy source you have ever come across? What tipped you off?
  • Can a source be biased and still contain true information? How would you handle that?
  • Why might two reliable sources still disagree with each other?

Mastery looks like: They independently run the who, when, why, evidence check on a new source and give a reasoned credibility judgment.

Common stumbles: Assuming anything that sounds official or is professionally designed must be credible.
