In crawling through the series of tubes (http://en.wikipedia.org/wiki/Series_of_tubes), I came across a fascinating article from the American Psychological Association entitled, Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments (http://www.apa.org/journals/features/psp7761121.pdf). (PDF) The paper, coauthored by Justin Kruger and David Dunning of Cornell University, is described thusly in the its abstract:
People tend to hold overly favorable views of their abilities in many social and intellectual domains. The authors suggest that this overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it. Across 4 studies, the authors found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although their test scores put them in the 12th percentile, they estimated themselves to be in the 62nd. Several analyses linked this miscalibration to deficits in metacognitive skill, or the capacity to distinguish accuracy from error. Paradoxically, improving the skills of participants, and thus increasing their metacognitive competence, helped them recognize the limitations of their abilities.
It's a fascinating, very accessible read, and explains a phenomenon we've all seen at one time or another: the clueless boss (or other bothersome coworker) who is so incompetent that he can't understand how incompetent he is. The authors suggest that the reason for the phenomenon is that the skills required to achieve competence are the same ones necessary to evaluate it:
In essence, we argue that the skills that engender competence in
a particular domain are often the very same skills necessary to
evaluate competence in that domain—one's own or anyone else's.
Because of this, incompetent individuals lack what cognitive psychologists variously term metacognition (Everson & Tobias, 1998), metamemory (Klin, Guizman, & Levine, 1997), metacomprehension (Maki, Jonas, & Kallod, 1994), or self-monitoring skills (Chi, Glaser, & Rees, 1982). These terms refer to the ability to know how well one is performing, when one is likely to be accurate in judgment, and when one is likely to be in error. For
example, consider the ability to write grammatical English. The skills that enable one to construct a grammatical sentence are the same skills necessary to recognize a grammatical sentence, and thus are the same skills necessary to determine if a grammatical mistake has been made. In short, the same knowledge that underlies the ability to produce correct judgment is also the knowledge that underlies the ability to recognize correct judgment. To lack the former is to be deficient in the latter.
