Dunning-Kruger effect is Autocorrelation.

Very highly intelligent people are not immune to either the Dunning-Kruger effect or the Gell-Mann amnesia effect.

I suspect that the (accurate) knowledge of one's own general intelligence can act as a risk enhancer, as well, misleading oneself into thinking full, or at least sufficient, knowledge of a field comes with less effort than is in reality required.

This much is sure: no person can be an expert in everything, so the more areas in which they claim expertise, the more probable it becomes that in at least one of those fields they have fooled themselves*, with the probability rapidly approaching one.

*And, unfortunately, fooling other non-experts, precisely because of their known native intelligence.
