Be right at all costs

Must we be right at all costs?
Hello, so it's been a few days since I wrote the introduction with my plan which is as follows:
I- to be right is to know how to tell the truth, to be logical
II- but it also means wanting to have the last word and showing bad faith
III- finally, we understand that being right is the sign of great wisdom

From there I have a blockage because I can't find any arguments or examples
