This week Ray sits down with the man best known as the godfather of Evidence Based Medicine (or EBM), Professor Gordon Guyatt. Together they explore the past, present and future of EBM, and look at how an approach encouraging doctors to look more rigorously at the evidence grew into a global reform movement to better inform all our healthcare decisions.

Like most global movements, EBM is not without its critics. Acknowledging this, Gordon shares his thoughts on prominent critiques that argue EBM has been 'hijacked' by commercial interests. And on a more personal note, he reflects on his early dreams of being a novelist, his four tilts at election to Canada's Parliament, and the many ways his two very different parents have shaped his world view.
