I think NTPs would be worst in the Military.
Why do people always assume that NFs would be? NFs would have the honor to do such a thing, in my opinion..I know I'd have the honor. My uncle is an INFP and he was in Desert Storm and was proud to risk his life for his beliefs. NTs wouldn't find much logic in tedious drills and training and tactics would be difficult. NTJs would, however, make good Military leaders, but NTPs in my opinion, would most likely hate it the most.
Stop thinking INFPs would be the worst! Jone of Arc was an INFP (or so they say) and she stood up for what she loved and fought for her country. NFs are all about pride and inspiration..so if they were inspired to do so, they could easily. Not every single NF is completely passive, it's soo annoying when people stereotype NFs as being like that. Many of the best freedom fighters and rebels were NFs.
I didn't ask who would hate it the most, but who would be worst typological fit. Also,I never said that every NF is completely passive. Interestingly enough, I am an NF, and an INFP at that. I don't consider myself, or most NF's that I have met to be passive people.
The military is very ESTJ in character, especially the ground combat services and amongst the enlisted. I am a military brat, wanted to join the military, spent time as DOD civilian on a military installation, have military friends, and did martial arts training with a number of former military people, many of whom were EF or SOF. I think ST's tend to have plenty of beefs and/or lack of respect for NF's, and the VAST majority of military personnel are ST's. The vast majority of military leaders [and civilian leaders], are TJ's, most of those being STJ's. [At my DOD job we had MBTI training, and the person giving that had personally typed ~20,000 people in her career. She said in all her time she met only *1* NFP at Colonel or higher rank. He was an ENFP and when she asked him why/how he put up with it, his response was something along the lines "to take care of the others", a very NFP thought. But one, one! person out of ~20,0000. Another of her stories: some colonel or general had his office at this training. Said leader decided that N,F, P were all bad, and wanted to get the individual test results so he could kick out every N,F, or P on his team and replace them with STJ's!]. I've read posters on this forum mention how F's are "totally out of place" amongst the military, as in extremely rare. My friend who went to the AF academy told me a story how when he was early on there they got together in groups and talked about, amongst other things, why they joined. One woman mentioned human relief efforts [airlifting food and stuff] and seemed completely unaware that usually the military does other stuff, much of which involves training to kill people. "our job is to drop bombs on people" "warhead to the forehead", etc. Read some discussions, for example on INTPc, about INTP's in the military, here why they say N and P are bad fits in general for the military. Read why F's say F is often out of place in the military. Read all the INFP discussions in MBTI books saying "INFP's don't like bureaucracy, shouldn't work for the government, shouldnt join the military, etc". There are easons those things are said. Yes, any of the types I selected can choose to join the military, and some of them do, but MOST of them don't and are VERY underrepresented in the military.
Individuals can always choose for themselves what to do, and are of course free to buck trends and expectations. With that said, certain types of people often tend to choose certain kinds of work while generally not-choosing other kinds of work. Statistically, if you look at large groups of people, you'll find that certain types generally don't end up certain places. Again, any individual can choose whatever they want, but collectively such decisions are often infrequent.
Let me add one more thing: I'm an INFP, I've done lots of things that INFP's don't usually do, and in a lot of ways I feel like my life is a list of what INFP's should NOT do. By doing all sorts of things that INFP's "should not do" 1) I have lots of immediate in-my-face understanding of WHY INFP's generally don't choose to do those things, and 2) when I look around I'm usually the only INFP, and almost as usually the only NF to be seen. Did I do things the that I did? Yes sir! Was I the ONLY INFP around that I saw doing these things? Yes sir! Does that suck? Yes sir! Do I recommend it? Avoiding lots of expletives, let me just say "no, not one iota".
Again, any individual can choose to do what they want. But there are reasons and forces why types of people USUALLY don't choose to do those things. For those who do choose those choices, prepare for the possibility that you will be the only person like yourself.
