In 1999, David Dunning and Justin Kruger did a series of studies evaluating people’s competence in certain areas, including grammar, humor and logic. The people in the studies were asked to evaluate their own abilities in each area. Dunning and Kruger found that people who scored low on the tests have the tendency to overestimate their abilities, indicating that people who lack skills tend to lack the ability to realize their shortcomings.
This principle has become known as the Dunning-Kruger effect. It occurs because only when people have skills in a given area are they equipped to evaluate their own skills. Admittedly, most people are overconfident in their abilities. They want to believe that they are more capable, knowledgeable and even superior to others, and when someone really wants something to be true, it can be hard for them to admit that it isn’t. By the way, the opposite of the Dunning-Kruger effect also happens: capable people have a more accurate view of their own abilities, and sometimes they even underestimate themselves.
It’s tempting (吸引人的) to think of the Dunning-Kruger effect as a problem. People may even laugh at those who think themselves more competent than they truly are, but everyone has areas where they lack competence, and the Dunning-Kruger effect means they may be relatively bad at self-evaluation in those areas. Even if someone is very intelligent in general, there are still things they don’t know much about. Expertise in one area cannot always be transferred to other areas.
That’s why it’s important to keep digging for information even when you think you’ve found answers. It can also be helpful to check your ideas with other people. Receiving negative feedback can hurt, but if you’re willing to listen, it can help you grow. Even just keeping in mind that the Dunning-Kruger effect exists can help you stay modest, accept criticism and, thus, keep learning throughout your life.
