Something other than inappropriate feedback due to absence of any strong performers in the immediate environment to compare with, plus reality distortion/denial and unwilling to look farther around? People who have managed to read two or three books in a whole life (well, one of them three times) are absolutely sure that reading is a total waste of time and should be even forbidden, while they are totally convinced that if they might be not the best person on earth (due to some external, uncontrollable misfortunes), but definitely right at the top of the whole humanity. Why, we have a full country of these.)
