This week we're talking about science and evidence in the political process. We'll talk to Dan Kahan, Professor of Law and Professor of Psychology at Yale Law School, about the Cultural Cognition Project, which studies group values and perceptions of risk in science communication. We'll speak to Shane Trimmer, Executive Director of Franklin's List, about their work to elect pro-science candidates. And biologist Katie Gibbs returns with an update on Evidence for Democracy, which advocates for the transparent use of evidence in Canadian government policy.
