It's a common misunderstanding of the Dunning-Kruger effect. In actuality, there's a direct relationship between how good a person thinks they are and how good they actually are. Not inverse. The Dunning-Kruger effect is that the people at the low end of the scale tend to rate themselves as slightly better than they are, and people at the high end of the scale tend to rate themselves as slightly worse than they are. The best people know they're good, but they tend to think they're not the best. The worst people know they're bad, but they tend to think they're not the worst.
