Beware the Expert, cont.

From the Science of Willpower by Kelly McGonigal:

Nevertheless, research has consistently shown that most people are not fans of reality when it comes to estimating their own abilities. We tend to overestimate our skills. And, in a cruel twist, the less ability you actually have, the more you think you do.

This common cognitive bias, known as the Dunning-Kruger effect, was first formally reported in 1999 by psychologists at Cornell University. These researchers found that most people overestimate their abilities in many domains, including humor, grammar, and logic. The effect is most pronounced in people who have the least skill; for example, those with a test score in the12th percentile would, on average, estimate themselves to be in the 62nd percentile.

In contrast, people who actually are above average are less likely to rate themselves so highly. Because they know more, they doubt themselves more. They know what it means to be really great — unlike those whose skills are so poor, they can’t recognize competence in others or their own lack of ability. The Cornell psychologists Dunning and Kuger concluded, “Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it.”

This seems to be adding some scientific research to a Beginner’s Mind.
