If Wheeler was too stupid to be a bank robber, perhaps he was also too stupid to know that he was too stupid to be a bank robber ? that is, his stupidity protected him from an awareness of his own stupidity.

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.
