SkeptiCal is the scientific skepticism conference brought to you by Northern California Skeptics.

“The biology class you wished you could have taken”: Kitzmiller v. Dover, 20 years later 2025 is 100 years after the Scopes Monkey Trial in Dayton, Tennessee, and 20 years after the 2005 Kitzmiller v. Dover court case, in which I participated while working at the National Center for Science Education. The Kitzmiller case included extensive expert testimony on the science of evolution, and the historical development of “intelligent design” and related antievolution efforts. While the case made in 2005 holds up very well, there have been interesting developments in both areas that I will review. These include work on the evolutionary origins of the bacterial flagellum done in a phylogenetic context, and work applying phylogenetic methods to trace the copying history of antievolutionist legislation. I will also reflect on lessons we learned during the case and how they remain relevant today. About the Speaker: Nick Matzke is a Senior Lecturer and Rutherford Discovery Fellow at the School of Biological Sciences, University of Auckland, New Zealand. From 2004-2007 he was a Public Information Project Director at the National Center for Science Education, and was heavily involved in the 2004-2005 Kitzmiller v. Dover trial in Pennsylvania about the constitutionality of teaching “intelligent design” creationism in public school biology classes. See less 🎙️ New to streaming or looking to level up?

Intelligent Design Theory (ID) is scorned by nearly all professional life scientists. Nevertheless, local and state boards of education throughout the United States have tried to mandate instruction in this “alternative” theory of evolution. Professor Nelson will discuss how ID succeeded politically even as it continues to fail scientifically. The secret to ID’s success draws from its advocates’ “recruitment” of consensus values like freedom and fairness, overshadowing the theory’s scientific shortcomings. Professor Nelson will focus on the communication strategies of ID advocates and opponents and will draw parallels between the ID battle and current controversies over climate change and vaccine resistance. About the Speaker Thomas E. Nelson is Professor of Political Science at The Ohio State University in Columbus, Ohio. He received his PhD in social psychology from the University of Michigan in 1992. He is the head of the political psychology PhD program at Ohio State that examines how theories and research methods from psychology help us understand politics, and how the study of politics broadens psychological theory. He is the author of Political Persuasion: The Use of Values in Communication (Oxford University Press, 2024) that explores how political advocates leverage the power of social values to increase support for their causes. The book includes an extensive case study of the ID movement and its opponents, and Prof. Nelson will draw from this material for his presentation.
