Very good, though I'd add something. Changing one's mind, or for that matter learning almost anything, involves realizing you were wrong. This can happen learning math, and it can happen in debate. It can happen in reading. Unfortunately, we now have a media ecosystem that rewards people in their mistaken beliefs by introducing them to lame supporting arguments and the triumphant vehemence of other wrong people. There's less incentive to appreciate the infinite value of realizing you are wrong.
