“Interestingly, one of the initial impediments to open-mindedness is not ignorance but ideology. This is especially true in America, where (particularly in “progressive” circles) we have politicized open-mindedness to the point that it isn’t so open-minded anymore. Indeed, regardless of whether your sympathies lean to the left or the right, you aren’t going to learn anything new if you continually use politics as a lens through which to view the world. At home, political convictions are a tool for getting things done within your community; on the road, political convictions are a clumsy set of experiential blinders, compelling you to seek evidence for conclusions you’ve already drawn.”
