D-K is one of my favorite patterns. This is the first time I've seen these charts. Some questions about methodology:
The x-axis shows quartile, not score results. If the range was between 80 and 90%, then all participants were accurate in assessing their ability as "above average". [EDIT] I doubt that's the case, but would rather see scores.
How was the self declared expertise in "humor" judged? That seems pretty subjective. Maybe the subject is hilarious to his or her friends.
Did the subject know what the examiner's definition of "logical reasoning" is? Was that street logic or discrete structures? What if the subject was able to glance at the test questions? Only then answer the question as it pertains to the test. How would the results change?
Grammar is idiomatic. In some places "over yonder" is contextually concise. Other grammatical forms may never occur. How is self-assessment over tacit expertise judged? Maybe another glance at the test?
Maybe Dunning-Kruger shows that there is a disconnect in how examiner and subject interpret a question? Maybe, it is a matter of saving face in saying that you're above average? Maybe, because the subjects are college students, that they actually are above average? Or maybe, these are above average participants that aren't quite sure of the question, so they say that they're above average?
