Living on Mt. Stupid - The Dunning-Kruger Effect
"...the Dunning-Kruger Effect is the tendency for people to misjudge their abilities. People with less than average abilities tend to overestimate their true abilities, while those with higher than average abilities tend to not realize how much better they are.
That is, some people are too stupid to know how stupid they are, while smart people assume most can do what they can. In their original 1999 paper entitled Unskilled and unaware of it: How difficulties in recognizing ones own incompetence lead to inflated self-assessments, Dunning and Kruger claimed that the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others.

On the other hand, the more educated are quiet.
Those in the Valley of Despair feel like frauds. For some reason, despite ample evidence to the contrary, some of those well on their way towards mastering a subject feel like they arent really that educated, their recognition is due to luck, or they have tricked those around them. This is common with PhD students, as they experience high levels of depression, even though they know far more about their chosen field than the general population."
