Typical "I know more than the experts" answer.
I think it's because of the way they see the problem domain. Both ways of seeing the problem domain look much the same.
I mean, a thoroughly explored domain and an utterly unexplored domain present much the same picture, in that...
There are not many unexplained mysteries hanging around.
Which may be translated to "The problem domain is thoroughly understood".
It's the problem of invisible stuff. You can't measure its extent.
Right, like I said, person with no domain knowledge alleges experts are making “flippant” and “unfounded guesses”.
What exactly were you trying to prove?
Let's be totally honest. Paleontologists have make astronomical errors in interpreting probabilities and statistics in the past.
