The Cato Unbound symposium on my book Democracy and Political Ignorance: Why Smaller Government is Smarter is wrapping up up today. I am grateful to political theorist Jeffrey Friedman, Yale Law School Professor Heather Gerken, and Sean Trende of RealClearPolitics for their thoughtful critiques of the book, and to Jason Kuznicki of Cato Unbound for his excellent work organizing and hosting this event. Here is a link to my final post in the exchange, which summarizes the discussion as a whole, and responds to final posts by Jeffrey Friedman and Sean Trende.
