Dunning-Kruger Effect

The less a person knows about a thing, the more they believe they know. While in that state they estimate that difficult tasks are much easier than they actually are. The more they learn the more they know they don't know and the more accurate their gauge of difficulty

“Watching an expert, the layman thought it looked so easy, he picked it up himself and failed spectacularly. The Duning Kruger Effect in full swing, he learned more and became less insulting to those with skills he could not yet glean.”
