Dunning and Kruger describe a common cognitive bias and make quantitative assertions that rest on statistical arguments. But their findings are often misinterpreted, misrepresented, and misunderstood. According to Tal Yarkoni, an associate professor of psychology at the University of Texas at Austin:

Their studies categorically didn’t show that incompetent people are more confident or arrogant than competent people. What they did show is [that] people in the top quartile for actual performance think they perform better than the people in the second quartile, who in turn think they perform better than the people in the third quartile, and so on. So the bias is definitively not that incompetent people think they’re better than competent people. Rather, it’s that incompetent people think they’re much better than they actually are. But they typically still don’t think they’re quite as good as people who, you know, actually are good. (It’s important to note that Dunning and Kruger never claimed to show that the unskilled think they’re better than the skilled; that’s just the way the finding is often interpreted by others.)
