Interesting, just recently read about similar concept from Chris Hadfield's book "An Astronaut's Guide to Life on Earth". He puts all team newcomers intro three categories minus ones, zeros and plus ones. Basically minus ones will think they always know better and do not spend effort on familiarizing themself with existing system, they also ignore epistemological category of "unknown unknowns". Chris recommends always to strive for being a zero at first.
