Scientists are increasingly finding their expertise questioned by non-experts who claim they’ve done their own “research.” Whether advocating Ivermectin to treat Covid, insisting that climate change is a hoax, or asserting that the Earth is flat, doubters are now dismissed by being told to “do your own research!” But is a Wiki page evidence? What about a YouTube video? What happens to our quest for truth along the way? Plus, a science historian goes to a Flat Earth convention to talk reason. Guests: Yvette Johnson-Walker – epidemiologist at the University of Illinois College of Veterinary Medicine, and affiliate faculty with the University of Illinois Chicago School of Public Health. Nathan Ballantyne – Professor of Philosophy at Fordham University, in New York. David Dunning – Social psychologist and Professor of Psychology at the University of Michigan. Lee McIntyre – Research fellow at the Center for Philosophy and History at Boston University, author of “Post-Truth,” and “How to Talk to a Science Denier: Conversations with Flat Earthers, Climate Deniers, and Others Who Defy Reason.” Learn more about your ad choices.
