The Dunning-Kruger Effect

Recently I listened to an episode of This American Life titled In Defense of Ignorance. In the episode, they discussed The Dunning–Kruger Effect, a cognitive bias wherein unskilled individuals suffer from illusory superiority, mistakenly assessing their ability to be much higher than is accurate. The theory was developed in experiments conducted by Dunning and Kruger of the department of psychology at Cornell University in 1999. The study was inspired by the case of McArthur Wheeler, a man who robbed two banks after covering his face with lemon juice in the mistaken belief that, because lemon juice is usable as invisible ink, it would prevent his face from being recorded on surveillance cameras.

Have you seen the Dunning-Kruger Effect in action in your workplace? You deal with all kinds of personalities in your workplace and need to use your emotional intelligence to remain effective. What do you do when you run into people with an unshakable sense of superiority? How do you keep doing your work well amongst them?
