How does science become public policy? It's not always as straightforward as it might seem. In his book "The Triumph of Doubt: Dark Money and the Science of Deception," leading public health expert and former Clinton/Obama administration official David Michaels shows how corporate interests often "manufacture uncertainty" in order to protect their profits. Using wide-ranging case studies from Big Tobacco, Volkswagen, American football, and talcum-based baby powder, Michaels exposes the disinformation playbook deployed by corporate-funded science to sow "doubt, denial, delay, distraction, deflection, and defense." With him, Bethany and Luigi discuss how we can fight back against manipulated science and replace the triumph of doubt with the triumph of truth.
