I concur that due to the fact they tend to be overeducated and ind0ctrinated, they do have that feeling of grandeur. They seem as if they are infallible and do not make mistakes. Their excuse is usually their SAT scores. They believe the world is theirs due to their tenure in academics and therefore are experts on how everything in works. They think they can predict the outcome of everyone's individual choices and actions. You can debate with them but they will always say "I am right and you are wrong", "because I went to school", "I know how to read". So on and so forth.
