Most people are not willing to have a Socratic style debate let alone admit they could ever be wrong. That is the root of the problem in our society today.
Hacker News is the only large forum where I see anything close to Socratic dialogues: At least a few times a week, I find myself upvoting both sides of a debate because the participants are really listening to each other and (seemingly) making a genuine effort to understand where the other side is coming from.
