Explanation for Morons

"Dunning and Kruger argued in their paper, “When people are incompetent in the strategies they adopt to achieve success and satisfaction, they suffer a dual burden: Not only do they reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the ability to realize it.  Instead, like Mr. Wheeler, they are left with the erroneous impression they are doing just fine.”
It became known as the Dunning-Kruger Effect — our incompetence masks our ability to recognize our incompetence.
There have been many psychological studies that tell us what we see and what we hear is shaped by our preferences, our wishes, our fears, our desires and so forth.  We literally see the world the way we want to see it.  But the Dunning-Kruger effect suggests that there is a problem beyond that.  Even if you are just the most honest, impartial person that you could be, you would still have a problem — namely, when your knowledge or expertise is imperfect, you really don’t know it.  Left to your own devices, you just don’t know it.   We’re not very good at knowing what we don’t know.
ERROL MORRIS:  Knowing what you don’t know?  Is this supposedly the hallmark of an intelligent person?
DAVID DUNNING:  That’s absolutely right.  It’s knowing that there are things you don’t know that you don’t know. [4] Donald Rumsfeld gave this speech about “unknown unknowns.”  It goes something like this: “There are things we know we know about terrorism.  There are things we know we don’t know.  And there are things that are unknown unknowns.  We don’t know that we don’t know.”  He got a lot of grief for that.  And I thought, “That’s the smartest and most modest thing I’ve heard in a year.”
David Dunning, in his book “Self-Insight,” calls the Dunning-Kruger Effect “the anosognosia of everyday life.”[10] When I first heard the word “anosognosia,” I had to look it up.  Here’s one definition: Anosognosia is a condition in which a person who suffers from a disability seems unaware of or denies the existence of his or her disability. [11]  Dunning‘s juxtaposition of anosognosia with everyday life is a surprising and suggestive turn of phrase.  After all, anosognosia comes originally from the world of neurology and is the name of a specific neurological disorder.
DAVID DUNNING:  An anosognosic patient who is paralyzed simply does not know that he is paralyzed.  If you put a pencil in front of them and ask them to pick up the pencil in front of their left hand they won’t do it.  And you ask them why, and they’ll say, “Well, I’m tired,” or “I don’t need a pencil.”  They literally aren’t alerted to their own paralysis.  There is some monitoring system on the right side of the brain that has been damaged, as well as the damage that’s related to the paralysis on the left side.  There is also something similar called “hemispatial neglect.”  It has to do with a kind of brain damage where people literally cannot see or they can’t pay attention to one side of their environment.  If they’re men, they literally only shave one half of their face.  And they’re not aware about the other half.  If you put food in front of them, they’ll eat half of what’s on the plate and then complain that there’s too little food.  You could think of the Dunning-Kruger Effect as a psychological version of this physiological problem. If you have, for lack of a better term, damage to your expertise or imperfection in your knowledge or skill, you’re left literally not knowing that you have that damage.  It was an analogy for us.[12]
This brings us in this next section to Joseph Babinski (1857-1932), the neurologist who gave anosognosia its name."
