Oh I was talking fictionally. Probably should've specified. I'm asking because it feels like every detective/spy in the media has a different type. Heck, I feel like Sherlock goes through total type changes just depending on who's playing him.
Detective: INTx types; if I INTJ, their Se should be well developed
Espionage: Something with a weak Feeling (best if the the fourth function is Fe, not Fi); I'll go with ExTJ; IxTPs are all a bunch of no-good procrastinators; INTJs might work unless they fall in love--then they're terrible for the job
Great men are like eagles, and build their nest on some lofty solitude.
Oh okay, that all makes sense. Just out of curiosity, how about nonfictional? Would it be a huge change from the fictional common types, and if so, why is that?
Non-fiction, espionage largely amounts to a combination of diplomacy by other means and data mining. It's both extremely boring and yet dangerous at the same time, especially if you're a double-agent who maybe betrayed. At best, the popular image we have of espionage is based partially on fact - that is how it was conducted during WWI and WWII. Check out the PM I sent you.
You can't have it both ways! If Ns are "sensotards" and can't be bothered with mundane detail or following procedures, then they're going to suck ass at detective or espionage work. ENTP might be one of the top five worst types for that line of work!
