I’m always impressed when someone can persuasively make their point and capture an audience’s attention sans slides. This is one of my favorite TED talks of all time, because it forces me to do something I’m not inclined to do: Disagree. Embrace Conflict. Risk sounding stupid.
One requirement Margaret mentions is right: Seeking people who are different than you and finding ways to work together requires patience and a willingness to be wrong, and beyond that, to change our mind. Most of us find issue with being wrong. However, more important than being potentially wrong is the fact that disagreeing has to do with caring.
It’s easy to go along with the status quo. It takes a high level of caring to disagree, not only for the sake of disagreeing, but constructively disagreeing to find stronger solutions to problems.
