For me, the claim is, "Why do you always have to be right?" I've made the mistake hundreds of times in my life where I put a lot of effort into a project, only to discover that I missed something obvious at the start that invalidated the whole approach. Like selecting the architecture-defining processor for an electronics design, completing the design around it, and then discovering weeks later that it's obsolete. It's not about ego. I've tried to explain that I want to be sure I am moving forward on the basis of correct information and reasoning. It's a desire to not risk wasting time & effort.
