Source to evaluate
A web page titled "5 superfoods that boost your immune system" appears on a site called wellnessglowblog.com. The article has no named author, ends with a link to buy a "$59 immunity bundle," gives no references, and carries no date. The same advice does not appear on health.gov.au.
Run the checklist
For each criterion, write what the page shows and tick whether it passes or fails.
| Criterion | What does this page show? | Pass / Fail |
|---|---|---|
| Author and expertise | ||
| Evidence and citations | ||
| Currency | ||
| Purpose and bias | ||
| Domain and publisher | ||
| Corroboration |
(a) Based on your checklist, is this page a valid and reliable source? Justify your judgement using at least two criteria.
1. The "buy now" link is part of the purpose criterion. Explain how a commercial purpose can introduce bias that weakens a source.
2. You want to corroborate the immune-system claim. Name one trusted Australian source you would check, and explain why it is a good choice.
