A polished page can contain errors, and an unfamiliar source can still provide useful evidence. Evaluate the claim and its support instead of judging only the appearance or popularity of the page. Identify the author, purpose, publication date, and evidence. Ask whether the author has relevant expertise and whether the cited material supports the exact claim. Separate an opinion, an advertisement, and a factual explanation. For a disputed fact, compare independent sources. A chart without units or a quotation without context may be misleading even when its numbers or words are genuine. Trace important claims to the original document when possible. If you cannot verify something, label it uncertain rather than repeating it confidently. Try it today: Choose one claim from your study material. Write what evidence would support it, locate that evidence, and record any limitation you found.
