You are assuming I already did not know this ?
No assumption needed. Your answers are the very proof.
IF you already knew it, why then do you then do it......
Exactly what Dunning warned about in the clip YOU linked to but you failed to heed his warning about "self"..... That's the WHOLE point of the Dunning-Kruger effect, its about the "self" failing to see SELF short falls, SELF error. Not having the skills or ability to SELF identify issues WITHIN.
You attempt to label others with the Dunning-Kruger but fail to understand it applies to the skills to SELF assess WITHIN. This failure is demonstrated proof that you don't understand the concept of SELF-ASSESSMENT failure and is proof of suffering from the Dunning-Kruger effect as Dunning CLEARLY warned the interviewer about in the link you linked to (Something it seems the interviewer himself also failed to understand the warning that Dunning was giving him).
A truly self aware person with the skills to self assess themselves and their own short falls would have no need to attempt to label others with a broad brush like you have as they would be all to aware of their OWN short falls and would instead spend the time focused on fixing or bettering their OWN self. They understand they must -
"first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother's eye".
When you go around pointing out the speck in others eye, its all to easy to overlook your own plank. It might make you "feel" better about yourself in the short term but it doesn't actually address your OWN issues so that you can grow and move forward in our constantly evolving self growth.
Dunning-Kruger are pointing out the FAILURE to SELF assess in the less intelligent and the failure to properly self assess their true level by the highly intelligent in relation to the less intelligent.
The LESS intelligent think everyone else is stupid.
The HIGHLY intelligent think everyone is AS intelligent as themselves.
Here YOU are telling everyone how stupid THEY are...........
The VERY definition of the Dunning-Kruger effect. But you don't have the very skills needed to SELF assess so you end up in this circular logic loop your stuck in, instead attempting to assess and label OTHERS and totally missing its about the skills to SELF assess OURSELVES.
Those that have the necessary skills assess THEMSELVES.
Those that don't have the necessary skills assess OTHERS.
What's the point, its not as if you will ever understand any of this anyway as you don't have the very skills needed to self assess in the first place to identify where your own logic is failing............
