What is the Dunning–Kruger Effect?

9. Impact of Dunning-Kruger Effect

The Dunning-Kruger effect has been criticized as intellectual snobbery and a way for 'smart' people to feel superior. This cognitive bias should not be dismissed so lightly. The Dunning-Kruger effect can have a negative impact on individuals, organizations, and society as a whole. Arrogance, overconfidence, and even a tendency to bully others, sometimes allow incompetent people to reach high positions. Those with real talent are frequently lost in the shuffle and overlooked. The tendency towards self-doubt that often manifests in intelligent, competent people sometimes prevents them from speaking out or trying to make changes. Charisma, confidence, and boasting often overcome true skill and ability. The Dunning-Kruger effect is even applicable to criminals. The original study was inspired by a bank robber who covered his face in lemon juice to be unrecognizable. Lemon juice is the active ingredient in invisible ink.
