> how X vs Y turned out
There's a cool idea that's related to that which also comes up in Ray Dalio's "Principles", which is to keep a log and do some kind of bean counting on who turns out to be right vs. wrong in situations of disagreements. The idea is that people who frequently turn out to be right should be given more influence. It's also a question that has been on my mind a lot in reflecting upon my career.
My observation has been that people have a very acute awareness of who the people are who they frequently find themselves disagreeing with versus who the people are who they seldom disagree with. And they have terrible memory when it comes to remembering what those disagreements were even about, let alone who ended up being right. If you are the "wronged party" in that dynamic, then bringing up your track record of disagreeing and being right is one of the worst things you can do.
People who disagree just for the sake of disagreeing are, in my mind, a myth, especially in the workplace where the stakes are high and disagreement tends to go hand-in-hand with conflict and power struggle and is therefore uncomfortable territory. Nobody would put themselves through that discomfort for nothing.
