Should women get routine mammograms? Should men get regular PSA exams? Robert Aronowitz of the University of Pennsylvania and the author of Risky Medicine talks with EconTalk host Russ Roberts about the increasing focus on risk reduction rather than health itself as a goal. Aronowitz discusses the social and political forces that push us toward more preventive testing even when those tests have not been shown to be effective. Aronowitz's perspective is a provocative look at the opportunity cost of risk-reduction.
