One lesson I learned is from a phrase I picked up called M.R.I. It means the “most respectful interpretation” of what someone’s saying to you. I don’t need everyone to be best friends, but I need to have a team with M.R.I. You can say anything to anyone, as long as you say it the right way. Maybe you need to preface it with: “I’m just curious, and I want to understand what you’re saying better. Right now, my point of view is quite different. So can you help me understand why you don’t want to do this, or why you wanted to do this?”
Let me point out one key idea here. Domeniconi does not simply argue for being polite. She's telling us that people need to adopt an "inquiry" orientation when working collaboratively with others. They need to seek deeper understanding of others' points of view, and they need to maintain a healthy curiosity. They cannot simply advocate for their own views. They have to be trying to learn more about others' reasoning. In so doing, they can find better solutions together than simply engaging in a win-lose, zero-sum battle that can lead to very dysfunctional interpersonal conflict.
