Hour 2: What is the role of science in public policy and what are the moral responsibilities of scientists? We’ll spend this hour with Heather Douglas, Ph.D., the Wolfe Chair of Science and Society at the University of Waterloo and author of “Science, Policy, and the Value-Free Ideal” (University of Pittsburgh Press, 2009). Douglas will deliver the UTD Center for Values in Medicine, Science and Technology Lecture this evening.
