This is closely related to a term we can borrow from the clinicians: A failure of “insight” into one’s disability: anosognosia, “a deficit of self-awareness, a condition in which a person who suffers some disability seems unaware of the existence of their disability.

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.”
