From Carolina Journal Radio Program No. 694: Libertarians and other liberty-minded thinkers often focus on individual rights and personal decisions. Michael Munger, professor of political science, economics, and public policy at Duke University, says they also should devote attention to how people make group decisions. Munger co-authored the 2015 book Choosing in Groups. It emphasizes the role of freely associating voluntary groups as an alternative to government coercion when it comes to making key decisions.
