I'm a bit suspicious of the application of the Dunning-Kruger effect. It postulates that those with little skill typically over estimate their skill set, acting accordingly. And, there may be some emperical evidence to support that.
BUT, politically, it's getting a lot of traction these day among elitists who apply this principle to Trump supporters and "deplorable Walmart types", who obviously know nothing, but think we do. Of course the lib professsors who postulate such stuff are positioned on their perceived cloud, peering down at us peons
SO, the Dunning-Kruger hypothesis, IMO, depends on where the observer is positioned and the observer's predetermined bias. It's possible that the proponents of this theory are inadvertantly their own victims...
