“At the international level, we’re talking about education, health, food and food security, and the environment—all of which are heavily affected by policy,” MSU economist Siddharth Chandra said. “We suggest that if you want to have policies that lead to outcomes that are stable and positive, you want to have a system in which there’s a lot of deliberation.”
As it happens, I'm reading a book called Unlearning Liberty: Campus Censorship and the End of American Debate by Greg Lukianoff of FIRE, the Foundation for Individual Rights in Education. He talks about how the chilling effect of college speech codes is that people are afraid to discuss or even mention controversial ideas, & so they leave school never having been challenged, live & associate only with people they agree with, and don't see any value in expressing unpopular opinions.
This makes so much sense & answers a question a lot of folks have posed over the last few years: How is it that so many people vote against their own self-interest? I guess a lack of being called to account for their ideology prevents them from seeing that there might be a better way to go about things.
