Where I interned last summer (/am still working currently), my boss is one of those guys, a computational quantum chemist. I actually can't imagine much of a better way to manage people. He's won enough respect from the people above him that, it's more like... he suggests a starship, and says it'll take a long time, but be worth it in the end, and they trust him. Consequently, he gave me a very long leash (once he established that I was being productive).
The thing I learned from him about managing is that 90% of the job is going out of your way to make life easy for your subordinates. This may have been just because I'm still in college and literally had no relevant work experience (just class-learning)... but I was pleased when he offered me the job, then pleased when he held the 'interview' (kind of) out at starbucks instead of in the office, then pleased when he was lax on all the "office-wide" rules, then again when he called me up (he was out of town) to offer suggestions before a presentation I had to give (when I told him I was practicing it and having a hard time), and pleased when he pointed me to another research organization (where he was on the committee of people choosing who got into the program) and told me I should apply because it wouldn't increase my work very much, but would give me another additional thing to put on my resume, etc.
The list goes on and on. Not all of that happened immediately, but basically, by the time I actually started work, I was so overwhelmed by how much effort he put into me first that it would have been impossible for me not to try my hardest at the job. Then my initial progress stunned him (quite frankly... I'm very good at programming/problem solving), and it turned into a "whatever you think would be good for this project: go ahead and do it" kind of thing--the INTP dream-job.
Bottom line is: if I ever end up in a position where I can manage people, I'm going to try to absorb every ounce of his style that I can, haha, because it was wildly successful. If I had to guess, I'd call him ENFP... which also might have something to do with it, because I have great success in getting along well with them.
