8/1/11: Merchants of Doubt

Aug 2, 2011

Historian Naomi Oreskes says that while the U.S. scientific community has led the world in research on issues like public health and environmental science, there's also a small group of scientists that mislead the public with ideas based on political agendas rather than science. Oreskes has written a book that explores how this has skewed our understanding of climate change, tobacco and more. She joins Doug to talk about these "Merchants of Doubt." (Rebroadcast)
