INTJ's have been said to have "inverted spines" in the J catagory, so I wouldn't be too concerned about the J trait that much. The person himself will be more important, and their past experiences here.
If you are unsure what I mean, well basically means we care about order and efficiency, but we do it our way. We can be very haphazard, procrastinators, and seemingly unorganized in our "real" life that can be perceived.
On a side, why are you concerned about the J factor alone?
Why do intjs get stereotyped as nerds? I hated the Matrix (I mean REALLY hated), never watched Star Trek, think George Lucus is a tool, dont play video games and drink straight whiskey. I chase girls, smoke cigarettes..shoot pool and have a mean anti-authority chip. Nerd has such a timid connotation attached to it....:steam:
I don't know how old you are , but I think this is an age thing. I was EXACTLY like this when I was younger (scarily so in fact: literally point by point) until I realised the error of my ways. I've stopped smoking (it was slowly killing me and I resented filling the pockets of rich tobacco executives that probably don't even smoke), took up exercise instead, stopped drinking as I realised women do not find drunks attractive and I'm more confident in myself as a person so don't need to hide behind alcohol (I have the occasional glass of wine with a meal now), rarely shoot pool but still enjoy a game (as I now rarely go to bars), have a mild interest in Star Trek (mainly 7 of 9 although find the techno babble annoying but I have always enjoyed the original series), enjoyed the matrix (although deeply loathed the sequels), do not often play video games (don't have time what with living my life etc.), have admitted to myself that I'm a geek although more on the normal side of the scale (although I'm probably deluding myself there) but still retain a healthy distrust of ANYONE in a position of authority (there are Freudian reasons for this e.g. goes back to school days).
I throw this out there although I have no idea how true this is but you could true sporting bars/events. I love soccer and American football and you can find me intently staring at the screen, analyzing the plays, watching the movements, trying to understand the general team styles, admiring the teamwork and lecturing my friends on what a team is doing right/wrong. I love sport more than anything and its fairly open atmosphere around sporting events. Does anything reckon sport is popular with INTJs?
