Yeah, I really strongly agree with that point. Every single time I see the Duning Kruger effect quoted it's used to dunk on some person perceived as incompetent (usually a highly-placed executive) as a way to say "No, look, all people in that position think they're geniuses but they're actually morons!" But... well, even if there weren't a thousand different possible confounders (regression to the mean, of plain confusion about the level of competence of the other students taking the test), the DK effect isn't that strong. People act like it's an uncanny valley of stupidity and hubris, when as presented it's more like perceived competence is only roughly correlated with actual competence, with minor bumps. And yet people keep invoking it as if it were the explanation behind all the incompetence in the world.
