Revisiting the Dunning-Kruger effect

Dunning-Kruger effect is often invoked to describe situations when we have vocal but incompetent majority—whom are vocal because they have low understanding of the subject matter and hence have fewer filters—and silent but competent minority—whom is silent because they have higher understanding of the subject matter and are more inclined to self-doubt.

The core idea behind this cognitive bias is that less competent people are ignorant of how incompetent they are. Eric C. Gaze, a Senior Lecturer in the Mathematics Department at Bowdoin College and Chair of the Baldwin Center for Learning and Teaching, and his team recently revisited the study conducted by Dunning and Kruger.

The idea that the least skilled are the most unaware of their incompetency is pervasive in science and pop culture. But a new analysis of the data shows that the Dunning-Kruger effect may not be true.
