Ignorance more frequently begets confidence than does knowledge
Whenever one encounters a gunloon, one is struck by their confidence in their knowledge of all things firearm-related. Not only do they fully understand the most technical minutiae of firearms but they are expert in the maintenance, repair, operation, and handling of same. Gun policy, history, and science are their fortes. More amazingly, they can comment authoritatively on scenarios they've never experienced, even claiming a better understanding than those who have encountered such situations.
Ever wonder why this is?
There is a scientific explanation. It's called the Dunning-Kruger Effect. To illustrate the D-K Effect--consider American Idol. During the early auditions, the television audience gets to hear some truly awful singing by folks who have literally spent days waiting in line for an audition. When they're rejected, many of these would-be performers are genuinely hurt, upset, and puzzled by the the judges' inability to recognize their obvious "talent."
The D-K Effect basically finds that bottom performers tend not to just overestimate their performance, but to vastly overestimate their performance and knowledge. OTOH, top performers tended to slightly underestimate their knowledge and performance. This makes sense; the more knowledgeable you are, the more experiences you've had and the more adept you are at assessing your performance relative to others gives you better insight into what areas you may need more work. If you're incompetent, you simply haven't the wherewithal to understand your deficiencies.
