"Dunning-Kruger" is yet another all-purpose non-argument of Nessie's that he uses to avoid real debate. We could go back and forth all day accusing and counter-accusing each other of D-K. Pointless waste of time. It goes without saying that in a debate, especially a hostile one, that both sides think the other is dumb, wrong, evil etc.
D-K is a result in social psychology about the relationship between self-assessment and objective performance. It has long been noted that self-assessment is not that accurate and often inflated. In surveys strong majorities rate themselves "above average." D-K suggests in addition that people at the high end may underrate themselves, i.e., D-K suggests that self-assessments tend to be more compressed toward average than actual performance. Incidentally, D-K did not suggest that self-assessment is negatively correlated with ability. It's a positive correlation, the line is just flatter. For example, if people were rating their own attractiveness, 1-10, you might get self-assessment scores clustering more toward the middle, say 4-7, whereas independent assessments would show a fuller range.
Of what relevance is this self-assessment literature to the debate over the Holocaust? Not much, imo. The author of a post (or article or book) could have an accurate or inaccurate self-assessment, biased in either direction. So what? I don't care because I can read what they say and judge it for myself. Their own self-assessment is neither here nor there.
In general, people are wildly overconfident in debates. D-K is not the primary reason for this. People project confidence for simple tactical reasons. It's to intimidate the opposition and manipulate undecideds. But the overconfidence gimmick can only take you so far. If the substance of what you are arguing is weak, this will eventually become apparent to thoughtful observers if you are forced to defend your position at length and in detail.
Nessie claims to be an expert on eyewitness behavior and analysis. And implicitly he presents himself as an expert on logic and fallacies. His self-regard is tremendous!

I will let people judge for themselves whether Nessie's self-assessments are accurate.
