Are you open to changing your mind on politics?

Is there any public policy issue that you think you have all figured out -- that you're willing to try to change your mind on?

David Leonhardt, opinion columnist for the New York Times, writes "Righteousness comes easily in these polarized times. We all have reasons for our opinions." But he observes that we tend to be surrounded by people who hold similar ones -- and the more we talk politics, the more confident we can become that we're right.” Leonhardt thinks this is a problem, that it's leading to groupthink and overconfidence -- even possibly in himself. So he's setting out this summer to rethink how confident he should be on certain topics -- and he's encouraging you to do the same.
