Professor Justin Kruger's joint research on self-assessment and performance is referenced
— February 24, 2017
Excerpt from the Harvard Business Review -- "A classic finding in the psychology literature is the Dunning-Kruger effect (named after David Dunning and Justin Kruger, who first described it): Poor performers in a domain are more prone to overestimate their ability than good performers. Why? Poor performers are unaware of the many elements that go into expert performance, and thus they are overly confident in their ability to carry out all of the tasks necessary to succeed."
