wow. i learned something today, after all the noise. thanks. the Dunning–Kruger effect is something that your education has passed in front of you but it is totally new to me as a "thing".
It nails some observational things i have noticed in other fields, particularly archaeology, and made me think of some things i have had to do in practice, explaining things to people that are totally convinced of a tangential but wrong hypothesis, often totally redneck in origin and having a kernel of truth embedded in a matrix of err which makes sorting it out difficult.
