A New York Post article “Why Losers Have Delusions of Grandeur” (May 23, 2010), indicated that identification of the Dunning-Kruger Syndrome derived from the cognitive bias evident in a criminal case. McArthur Wheeler reportedly robbed banks with his face covered with lemon juice because he believed lemon juice would make his face invisible to the surveillance cameras. His incompetence was based on his mistaken ideas of the chemical properties of lemon juice, thinking that it formed a type of invisible ink. Much of the incorrect self-assessment of competence may result from a person's ignorance of the standards of performance of a given activity. In addition, in comparison with high performer, poor performers do not seem to learn from feedback that suggests a need for them to improve. Too bad!
