Tamsen Webster explains how people defend fixed positions during disagreements, using an example of choosing between downtown or by the park. She notes that many books address arguing positions.
The issue is that when there's disagreement about that, like one person says, let's go for the one downtown, and the other one goes, I want the one by the park, and you're just stuck on this is my position, literally downtown, no park. Each of you were defending a position that you've landed on, and that's normal. And in fact, there's been a lot of books written on how we tend to argue positions.
