This week, we examine the ways that society and science inform and influence each other. We're joined by Marie-Claire Shanahan, Professor of Science Education at the University of Alberta, and President of the Canadian Science Education Research Group, to discuss how science fits into the broader framework of our common culture. And we'll talk to science writer Mike McRae, author of the new book "Tribal Science: Brains, Beliefs and Bad Ideas," that looks at how brains that evolved to maintain social connections can manage to make objective observations.
