Thank you! You are most welcome!! I have been on HC for quite a few years now and yours is the most sincere "apology" I have seen offered on any thread! I guess I have become too used to dealing with arrogant and ignorant AH who are completely used to shooting from the cover of anonymity that the internet provides. It seems to be a common problem on HC and it is reassuring to find that not all others are so motivated!
On a couple of other forums I have followed there are some who really are classical Dunning-Kruger types, and of course they never back down:
https://en.m.wikipedia.org/wiki/Dunning–Kruger_effect
"... In the field of psychology, the Dunning–Kruger effect is a cognitive bias in which people assess their cognitive ability as greater than it is. It is related to the cognitive bias of illusory superiority and comes from the inability of people to recognize their lack of ability. Without the self-awareness of metacognition, people cannot objectively evaluate their competence or incompetence.[1] As described by social psychologists David Dunning and Justin Kruger, the cognitive bias of illusory superiority results from an internal illusion in people of low ability and from an external misperception in people of high ability; that is, "the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others."[1]
The psychological phenomenon of illusory superiority was identified as a form of cognitive bias in Kruger and Dunning's 1999 study, "Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments".[1]
The identification derived from the cognitive bias evident in the criminal case of McArthur Wheeler, who robbed banks while his face was covered with lemon juice, which he believed would make it invisible to the surveillance cameras. This belief was based on his misunderstanding of the chemical properties of lemon juice as an invisible ink.[2] ..."
The only problem with this is, once you see this in action you see it everywhere!
