Start with the stakes
The more serious the consequence, the stronger the evidence should be. A restaurant suggestion and a medical decision do not require the same level of verification.
Before researching, decide what could happen if the advice is wrong. That determines how many sources and what level of expertise you need.
Identify who is speaking
Look for a real author or accountable organization, relevant experience, a way to contact the publisher, and a clear publication or update date. Expertise in one field does not automatically transfer to another.
Look for the original source
A confident claim may have passed through several summaries. Follow citations back to official documentation, the actual study, the law, or the organization responsible for the information.
Check incentives
Ask how the publisher benefits. Advice can still be useful when it supports a product or earns commission, but that relationship should be visible and considered.
Compare independent sources
Look for agreement from sources that did not simply copy one another. When reputable sources disagree, understand why rather than averaging their conclusions.
Watch for warning signs
- Guaranteed outcomes or artificial urgency
- Claims that cannot be checked
- Testimonials presented as universal proof
- Important limitations left unexplained
- A request for sensitive information before trust is established
Know when online research is not enough
For high-stakes medical, legal, financial, or safety decisions, online information should help you prepare better questions—not replace a qualified professional who understands your circumstances.
