In the book "Principles" by Ray Dalio, he argues that when someone criticizes you or opposes your opinion, you should at least briefly consider the possibility that they are completely right and you are completely wrong.

Well, I may be misquoting him, but I remember getting the idea from the book, and I now find it hugely helpful to challenge myself like this when I find my opinion is in conflict with another person's. Working from "Am I wrong?" breaks down a of the ego barriers that are erected when you instead begin by defending a position you already hold.
