this kind of test is interesting because the self-reported nature essentially requires a high degree of self-awareness to score yourself as difficult — and while there are a few truly bad natures assholes out there, i’d say the majority of people who have a high degree of self awareness are actually not particularly difficult.
on the flip side, i think one of the hallmarks of truly difficult people is lack of the self-awareness, both about how they come across but also understanding what about themselves drives their actions.
would be interesting to see self-assessed scores against peer assessed
