Evidence matters in many of the decisions we make - as patients, consumers, voters and citizens. If you want to know whether a claim made in a policy, newspaper article, advert or product is backed by scientific evidence, use Sense About Science's postcard to Ask for Evidence.
For copies of the postcard please email firstname.lastname@example.org
Alternatively use our online form to generate an email to request evidence.
Or print a PDF copy of the postcard, fill in the details of the claim, put it in an envelope and send it off.
Read about other ways to request evidence, advice on how to do it and how to make sense of evidence on the Ask for Evidence homepage.
