How to spot health misinformation
Misinformation spreads quickly because it’s simple, emotional and gives a sense of control. Corrections are almost always longer and less appealing. So it helps to have a few reflexes ready.
Warning signs
- Promises a quick cure or guaranteed results.
- Claims there’s a truth “doctors are hiding”.
- Sells a product alongside the advice.
- Relies on personal testimonials. One story proves nothing about most people.
- Doesn’t name an author or cite sources you can check.
- Uses fear or urgency to push you to share it.
A single study doesn’t change medicine
Results in mice, in cells, or from a small study are the start of a question, not an answer. Real confidence comes from multiple studies pointing the same way, and from systematic reviews.
Where to check
- Your national or regional public health authority.
- The World Health Organization (who.int).
- Cochrane (cochrane.org), for evidence reviews.
Simple rule: if you’re not sure, don’t share. One minute of checking stops a falsehood from reaching more people.
