The Dunning-Kruger effect

The Dunning–Kruger effect is a cognitive bias in which unskilled individuals suffer from illusory superiority. These people mistakenly rate their ability much higher than average. This bias is attributed to an inability of unskilled people to recognize their own shortcomings.

In their research, Dunning and Kruger noted that incompetent people will:

  • tend to overestimate their own level of skill.
  • fail to recognize genuine skill in others.
  • fail to recognize the extremity of their inadequacy.
  • recognize and acknowledge their own previous lack of skill, if they are exposed to training for that skill.

Turns out Bertrand Russell was right all along:

One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision.
