Here is an interesting article covering D-K.
The Dunning Kruger Effect is a psychological phenomenon in which people of the lowest ability in a subject rate themselves as most competent, compared to others. Ironically, people who lack the most knowledge on a topic also lack the ability to recognize their own mistakes and errors, making them exceptionally confident and biased self-evaluators. They are also unable to fairly judge other peoples performance.
Yep, that’s the one.
Amazing how those D-K people have the ability to rise in management far faster than the competent and deserving.
