Build a personal health-information checklist

A reliable-looking website is not automatically a reliable source. A short checklist can help you decide whether information deserves your attention. You do not have to investigate every page like a researcher, but a few questions are useful before acting on a health claim.

A practical starting point

Look for the owner of the site, the purpose of the page, identifiable sources, and a current review or update date. Notice whether an article is trying to sell a product. A testimonial may describe someone's experience, but it cannot establish that a treatment is safe or effective for everyone.

What it can look like

Save two or three dependable sources you can return to. When a new claim appears, compare it with those sources and ask whether it is relevant to you. If the page hides its authorship, makes sweeping promises, or discourages professional care, step back. Share uncertain information as a question rather than presenting it to others as established fact.

Keep the checklist short enough to use

Save a note with four prompts: who wrote it, what supports it, when it was updated, and what it is selling. A page can answer those questions and still need comparison with another source. Read beyond a single citation: a link may concern a different population or a weaker claim than the article suggests. Keep personal details out of online symptom quizzes unless you understand how the data will be used. When a question could change treatment, bring the claim and its source to a clinician instead of using the checklist as a diagnosis tool.

Three small steps

• Check ownership, purpose, evidence, and the date of the information.
• Look for clear disclosure when money or advertising is involved.
• Ask a qualified professional before applying advice to a medical decision.
