What are some examples of people being blindsided because of self-importance?

I’m writing a piece on self-importance as a harm to our society. I make the claim that our expectations of limitless learning (knowing all the answers) gives us self-importance, because we typically will just make something up if we don’t have a satisfiable answer. Since we make it up, it typically involves . . . us . . . generating self-importance. However, I also need to prove that this approach to knowledge makes us easy to blindside.

Currently, I’m using the example of the USS City of Corpus Christi. The navy originally named the Los Angeles class nuclear attack sub the USS Corpus Christi, to generate support for the navy in the port city of Corpus Christi, TX. Of course, the catholic church freaked out that we had a nuclear attack sub named “Body of Christ”, so the name was changed to the USS City of Corpus Christi. The justification is that the Navy thought it had solved its problem of low support in the port city, so it didn’t consider the other perspective. As such, the navy got blindsided by the Catholic churches demands, and it turned into a public relations scandal.

Does anyone have an example they think might fit?
