Not often, but I do change my mind quickly when I finally realise something I've never thought about before. It is rare, but when someone actually proposes logical, non-opinion reasons for why I am wrong about something, I'm quick to admit I was wrong or possibly wrong. Often times, I'll need to think over the thing in question for a while in order to make up my mind again. Even if my opinion on said thing is the same in the end, my stance on it in entirety feels different. I may be less enthusiastic or more forgiving, etc.
