When I went to college, I joined a philosophical debating group. We didn't score debate; the only way to win was by winning over a convert or by being converted yourself. When people stood for office, they'd often be asked "Have you ever broken someone on the floor?" and "Have you ever been broken on the floor?" (we had a pretty pugilistic affect so "breaking on the floor" was our way of saying "get questions following your speech that either changed your mind or made you really uncertain).

Until I found LW, it was the first culture I was part of where it was really honorable to admit error, but not in a cringe-y "who can really know?" way. The debate group was also the first place I met really smart people who disagreed with me on obvious-feeling things, so I got a lot more curious about which of us should break.
