if it is in a similar context of a Platonic dialogue, i think it can do some good....but unfortunately that wholly depends on the willingness of the participants to be wrong as well as right.
if people are more willing to accept they could be misinformed or mistaken, or their viewpoint could be different, et. al,; it could be a powerful tool for broadening horizons...
however...and this is with a heavy heart to say...perhaps that requires a level of honesty people are uncomfortable with, in that partially it has to admit some level of ignorance, fear, shame. So many times we train ourselves to counter these negative emotions because they are unpleasant and we often thwart our own opportunities for growth in favor of medium status quo.
And since people aren't usually as honest with themselves as they could be, debates become these methods of employing the cruelest aspects of our civilized culture: one where barbs are freely thrown and our points are whittled into thinly veiled attacks. People are offensive or defensive, guarding from their behavior externalized and projected onto others based on their own understanding of the issues and so much gets lost...
so that as we know it, debate becomes a swordfight of words, where people don't think enough about what is actually being said, but only instead focus the energy and efforts on a way to sharpen our ability to attack each other..... No one listens when they need to get the jump. People don't read each others work or try to hear the intention. We read each others words as if looking for ammunition, and disregard the meat of the matter for the mere opportunity to one up. I'm equally guilty of this so its not like I'm setting myself apart from this at all. But I hope that being cognizant helps me reflect on my behavior and be a bit more cautious in my speech, though since i'm very human, that isn't always guaranteed.
I can't guarantee the level of honesty of my opponent and can only be responsible for my own, so the only choice I have is to take things at face value, while also honing my observation skills to be more aware of when someone appears to be an opportunist as opposed to someone hoping to broaden their horizons. Oh and exposure.....always better to ask someone to clarify without derision so that you know what specifically you're responding to. The Light is the best disinfectant. When all manner of hands are exposed, either by different truths or by allowance of vulnerability, then we can make progress. We can grow. We can learn.
