For example, I'm in the top 2% of aptitude tests. ISFP's are supposed to be amongst the lowest for scores in aptitude tests. Easy for me to mistype, when intuitives are the only ones who are 'supposed' to have aptitude for big picture abstractions/patterns, lowly ISFP's aren't supposed to be able to do well at aptitude tests.
The interesting thing would be if people mistakenly type as INxx because they do well on aptitude assessments (or other such things). What if the supposed INxx's in those stats are actually a slew of other types, they were just labeled INxx for reasons such as being able to comprehend abstractions? Even if it's not actually their preference?
