Dunning Kruger effect

The problem with the Dunning-Kruger effect is that it is an analogue quantity on one or several of multiple spectra.

Which means no-one is immune, and there is always someone who knows something you don't (and DK excepted) is annoyingly correct!

Of course I could be deluding myself, if I was exhibiting DK, but how would I know?

I know! Post on the Mudcat, but how would I know the nay sayers didn't exhibit?

My brain hurts............
