I think that’s what I said.
Maybe it is what you meant to say, but the words... don't speak to how or why minds do or do not change. So no, you didn't say what I said.
Edit to add: It has little to do with the kind of person. It isn't like Person A will never change their mind, and Person B is always open to new ideas. Each of us is a mixed bag, and our willingness to change has to do with the topic, the person's emotional link to that topic, and how the new idea is positioned and presented. Each of us will thus be stubborn on some things, and easy to move on other things.
