Is there a study which has shown a decrease in Dunning-Kruger effect with varying competence over time? If the effect is real, then you’d see more accurate self-assessments with increasing competence.

I also think these self-assessment vs actual performance studies don’t control for post-assessment cognitive stress. Stress almost always impairs judgment, and I wonder if asking for a self-assessment on the day of the exam and sometime after the exam would show a difference. If stress is a factor for self-assessment, then both high and low performers will score themselves more accurately given more time after a test.

Looking at the study design of this paper, I am not sure how the authors themselves would assess its strength for the kind of broad claim they’re making…And we’ve already seen many studies on this type of claim, so I am confused why the authors didn’t ask the “next step” type of question as I mentioned above.
