at least there seems to be agreement on isXj anyway, for the most part.
xntp seems stable, but in a very passionate way, so i'd not really call that 'the most stable type.' seems like they are more likely to get overheated and into an intenseness.
my husband is better at dealing with day to day stuff with people than me. he doesn't seem quite as introverted about dealing with errands and people regarding the bank, insurance, calling people, the contractor, the excavator, etc. as me. but maybe that comes to istjs more with age and experience? he's 40.
