I've been looking for a pair or words that mean that a person doesn't have all the details and doesn't realize that they do not, and its opposite counter part.
I was thinking the word "partialist" would cover the first thing, but this turned out to be a DSM-IV manual sexual disorder, despite it sounding right.
For example, "He was a partialist, he didn't know what he didn't know."
I thought that the opposite would be a "comprehensivalist" or someone who knows they have all the details.
