When the hugely popular podcast Freakonomics Radio ran a three-part series around the science of medicine, we interviewed Ben Goldacre, University of Oxford research fellow and author of best sellers Bad Science and Bad Pharma. In the second episode he talks about how ineffective and even dangerous drugs make it to market. He suggests one reason is that clinical trials are often run on “dream patients” who aren’t representative of a larger population. In the last episode he gives some insight into why medical error is the third-leading cause of death in the U.S. Listen to the whole series here.
