(Excerpt from Barking Up the Wrong Tree by Eric Barker)
Incompetence is a problem that inexperienced people have, and all things being equal, we don’t entrust inexperienced people with all that much power or authority. Overconfidence is usually the mistake of experts, and we do give them a lot of power and authority. Plain and simple, incompetence is frustrating, but the people guilty of it usually can’t screw things up that bad. The people guilty of overconfidence can do much more damage.
