I am seeing the X-Files now one episode per week again since some time (showing them in TV), right from start. The series was really great and I watched it earlier some time, but it is too long ago to remember about what type the other characters were. Wasn't shown in TV for long time (or I didn't see it at least). So I have only an opinion to Mulder and Scully, because the other characters didn't appear yet or only rarely.
I also think that INFP fits better to Mulder, for the reasons Benny mentioned, and he seems more like Fi/Ne to me. But I find it always a bit difficult with TV characters at the end to make a decision.
Scully INTJ might be possible and would be my best bet as well.
I'll argue that Scully is ISTJ. She seems very SJ, doesn't she? With the rigid skepticism about the paranormal, strong religious convictions, etc. She's incredibly loyal to people she loves rather than concepts or ideals. I don't really see Ni in her at all.
Scully does behave like an ISTJ. Definitely IxTJ though. Smoking man is a great example of an INTJ in my opinion. If you've ever seen the episode that tells the smoking man's story it's very clear what type he is. I'm not sure about Doggett. I stopped watching when Mulder left. The Lone gunman are probably all INTP's or at least NTP's. As for Krycheck... I'd say ESTP. ISTJ for Skinner makes a lot of sense too.
Mulder is definitely not a J, and clearly either an INTP or INFP.
Talk about probing. He epitomizes truth and the seeking of it. He has a total NP approach to problem solving; thinking outside of the box, prossessing every possibility, not sleeping until he knows the truth, doing anything to attain the truth, etc etc.
No freaking way is he an INFJ.
Plus, you'd almost have to be a P to be working side by side with Scully all the time :P
Is it that by its indefiniteness it shadows forth the heartless voids and immensities of the universe, and thus stabs us from behind with the thought of annihilation, when beholding the white depths of the milky way?
I'll have to agree with the otherwise strayed children of the P-clan, for once.
Mulder is a total P. Come on, look at his spare room that is full of boxes, unused furniture and general crap.
Now we're talking unhealthy amounts of P, here.
It isn't until his body gets taken over by some other guy a while into the series that his place actually goes squeaky neat.
His messiness is actually a theme theme in the beginning. The parts where the viewers "get to know him".
And the other point, that he is way too "laid back" to be a J... Yeah, that too.
There is no way any INTJ would behave in that manner without drugs, depression or sleep-deprivation.
It's the day i'll die when I see an INTJ move about hazily with a dull and slow expression and slack lips.
NTJs have a more stern outlook, that's why people often ask us if we are angry.
Set jaw, sorta-kinda intense stare, sometimes tensed face in its entirety.
It's got very little to do with the shape of the face and such, it's just a manner of behavior that i've noticed.
I'd call him almost 90-100% P. INTP, probably. They don't care much for appearance, in general, it seems. Posture, clothes, car, home yadayada.
JockTheMotie excepted. We all know you're a huge fashion victim
Mightier than the tread of marching armies is the power of an idea whose time has come
So I'm starting to watch this show now lol, I'll report my findings as I progress.
