+### Dunning-Kruger Effect
+
+[Dunning-Kruger Effect on Wikipedia](https://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect)
+
+In the field of psychology, the Dunning–Kruger effect is a cognitive bias in which people with low ability at a task overestimate their ability. It is related to the cognitive bias of illusory superiority and comes from the inability of people to recognize their lack of ability. Without the self-awareness of metacognition, people cannot objectively evaluate their competence or incompetence. People experiencing this bias are said to be at the top of "Mount Stupid," (refer to the graph below)-

+The effect suggests that poor performers are usually not in a position to recognize the shortcomings in their performance.
