Dunning–Kruger Effect

Here is one more term that I keep using and more people should know about. It is the Dunning-Kruger effect. The TL;DR is that stupid people are too limited to know that they are, in fact, below average. I’m sure you can find creative ways to apply this to the world around you…

The Dunning–Kruger effect is a cognitive bias which can manifest in one of two ways:

Unskilled individuals suffer from illusory superiority, mistakenly rating their ability much higher than is accurate. This bias is attributed to a metacognitive inability of the unskilled to recognize their ineptitude.[1]

Those persons to whom a skill or set of skills come easily may find themselves with weak self-confidence, as they may falsely assume that others have an equivalent understanding.

David Dunning and Justin Kruger of Cornell University conclude, “the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others”.[2]
