I used ideas I learned here to resolve a problem that I've failed at for over 10 years.

I was in an volatile arguement. My base rate of regreting arguements with this person is >90% over my entire adult life. I was really confident, perhaps even arrogant in hindsight. Then I remembered to think of our disagreement as travelers comparing independatly composed maps against a common territory. I proceded to draw a causailty DAG representing my own thinking. He added some nodes and edges I hadn't considered, but made sense after listening to him.

I felt the confidence of my position slipping away in my mind as the murkiness of uncertainty appeared. We could both easily be right, but the deciding information was out of reach for the time being. Our emotional arousal deflated. He felt good, reminded of his career as an engineer using fishbone diagrams.

It was the most pleasant ending I can remember compared to how our intense disagreements of utterly trival matters usually end: anger, bitterness, despondency, regret. I used a thinking tool, and changed minds, including my own, in a way I didn't anticipate. It felt strange, but good.

Not awesome by most cultural standards, but I think this is the only place where a simple story of changing my mind might be worth sharing.
