This week, we’re looking at some common assumptions about healthcare, including the well-known benefits – and less discussed costs – of popular screening technologies. We’re joined by drug policy researcher Alan Cassels, to talk about his book Seeking Sickness: Medical Screening and the Misguided Hunt for Disease. And we’ll speak to paramedic and skeptical blogger Michael Kruse about Bad Science Watch, a new non-profit watchdog organization dedicated to improving the lives of Canadians by countering bad science.
