Ask for evidence

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, ask the people making the claim to provide it. 

• We can help you ask for the evidence.
• Read some advice on how to ask, and look at other people's experiences.
• Our documents "I've got nothing to lose by trying it” and “I don’t know what to believe” can help you weigh up claims about cures or treatments. 
• Send off a postcard to request evidence.
• Don't forget to let us know how you get on, or if we can help.
