In the field of psychology, the Dunning-Kruger effect is a cognitive bias, wherein people of low ability suffer from illusory superiority. In simple terms, people that are not as intelligent, think they are super intelligent.
The effect explains how people mistakenly asses their cognitive ability as greater than it is. The effect derives from the metacognitive inability of low-ability persons to recognize their own limits.
