Ask for Evidence Launch


We hear all kinds of claims about what is good for our health, bad for the environment, how to avoid cancer, how to improve education, cut crime, cure disease or improve food. Some are based on reliable evidence and scientific rigour. Many are not. How can we tell the difference? 

VoYS USA has launched an ‘Ask for Evidence’ campaign to encourage people to question the claims they see in newspapers, on TV, in adverts and from policy makers. It launches on Valentine’s Day, so a group of early career researchers had a quick look at the evidence behind aphrodisiac claims about oysters, rhino horn and more, and produced an alternative Valentine’s greeting.

Read the press release of the launch.

Contact Morgan Thompson at VoYS USA to get involved.

Visit the Ask for Evidence pages for help with requesting and understanding evidence.
