Mini Lesson
Not every website tells the truth. Some online sources are written by experts and checked by editors. Others are written by anyone without checking the facts. Learning to evaluate a source — before using it in your research — protects you from spreading misinformation.
The SIFT Method
- Stop — pause before sharing or trusting anything you read.
- Investigate the source — who wrote it? What organization is behind it?
- Find better coverage — look for other sources that say the same thing.
- Trace claims — go back to the original source or data being cited.
Reliable vs Unreliable Clues
- Reliable: author named, date given, references cited, professional website (.org, .edu, .gov).
- Unreliable: no author, no date, sensational headlines, many spelling errors, no references.
- Be careful with .com sites — some are excellent, but many are not fact-checked.
The best check: can you find at least TWO other trusted sources that say the same thing? If yes, the information is likely reliable.
