As soon as a thought comes into your mind the ego tries to claim it. Instead of the best idea winning we want our idea to win. People in companies like to do things their way because they came up with it. New ideas are dismissed even though they might be better. They are dismissed because things are done the way they have always been done.
The idea of meritocracy is letting the best ideas win out. Even if the idea is not yours you will embrace it because fundamentally it is a better idea. Great ideas get the greatest results. When you lose the attachment of yours vs someone else’s you can look at the ideas without biased.
