“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."*This article leads off with a description of a miscreant who was arrested soon after he robbed a bank, in broad daylight, wearing no mask or disguise.
Astonished was he when the cops nabbed him in short order, as he had rubbed lemon juice on his face assuming it would conceal his image from cameras.
This is the kind of thing that makes the words "jury of your peers" scary.
