This is seems largely expected from Dunning and Kruger's paper.
The true Dunning-Kruger effect is not that low-skill individuals believe they're better than high-skill individuals but that low-skill individuals do not know what skill looks like. (Hence the title "Unskilled and unaware of it: how difficulties in recognizing one's own incompetence lead to inflated self-assessments").
When you cannot evaluate the output of something then _any_ output looks good.
