The Dunning–Kruger effect is a cognitive bias in which unskilled people make poor decisions and reach erroneous conclusions, but their incompetence denies them the metacognitive ability to recognize their mistakes.
At first I thought this was a joke and was referencing that show “The Office.” Then I realized Dunder Mifflin and Dunning-Kruger were not the same thing. Nonetheless I find this troubling. What’s more interesting is that it seems to be more prevalent among Americans.
