The author presents the case how D-K is misunderstood, then why one might suspect it is a mathematical artifact from measurement error, but then shows with a model that there is some evidence for Dunning-Kruger effect, as some observed data are reliably explained with an additive perception bias + noise effect (or a non-linear perception distortion effect).
That’s impressive, considering D-K isn’t real.
The following blog post might be of interest to anyone who either claims Dunning-Kruger means that low-skill people think they are highly skilled or claims Dunning-Kruger is not real: http://haines-lab.com/post/2021-01-10-modeling-classic-effects-dunning-kruger/
