Interesting. Do we have any good information on the attributes of discussions or debates that are the most likely to educate the other person when they disagree?

Something I've noticed: when someone takes the "conquer the debate" adversarial approach, a typical-minded audience appears more likely to be interested and side with the "winner" than if the person takes a much more reserved and cooperative approach despite having just as supported arguments. Maybe the first works well for typical audiences and the second for above-typical ones?

I hope you've noticed you changed the subject here. In the first paragraph you're trying to persuade the person with whom you are conversing; in the second paragraph you're trying to convince an audience. They might well require entirely different methods.
