Philosopher and author Jacob Stegenga of the University of Cambridge talks about his book Medical Nihilism with EconTalk host Russ Roberts. Stegenga argues that many medical treatments either fail to achieve their intended goals or achieve those goals with many negative side effects. Stegenga argues that the approval process for pharmaceuticals, for example, exaggerates benefits and underestimates costs. He criticizes the FDA approval process for approving too many drugs that are not sufficiently helpful relative to their side effects. Stegenga argues for a more realistic understanding of what medical practice can and cannot achieve.
