The Dunning–Kruger effect in a nutshell describes the behaviour of those suffering from illusory superiority in ignoring the abilities of others. You will often see that this pattern is very much in existence with the architecture community as well as with business owners. Often it occurs together with the inability to ask questions, as they are expected to know all. Roman generals knew about the Dunning–Kruger effect, but not by that name and they constantly placed servants to remind them that they were no gods and had to actively doubt themselves.
In classical art education this exercise of self critic is thought however with engineering and science it is not emphasised in the way, as in many cultures scientists and engineers are not supposed to be promoted in top positions. The problem is once you get to a point of power you have to reminded that you are just part of a team and divine.
