math prof, INTP -- laid back and casual. very smart, into theoretics. the only person who actually ever made me like math. also had a realistic bent (i'm guessing e5w6), used a unit to teach us about mortgages and interest (thank god). used another unit for pure logic. snarky and wouldn't hesitate to make fun of people being idiots, but was always available if you wanted his help. also pretty involved in university life. reminds me a lot of my brother - quite social but really more of a Ti dom than Ne dom.
psych 101 prof, INFP -- one of the sweetest, most out-there professors ever. cancelled class a good 25% of the time, and was often late. went on random theoretical tangents about his time as a practicing psychologist instead of staying on course topic, which to me was way more interesting anyway since it was intro psych. was once voted head of the department because he neglected to show up to a faculty meeting. i liked having 1-on-1 conversations with him. he was above all very compassionate, with a heap of whimsy and a touch of sadness. probably 4w5.
ethics prof, ENFJ -- the kind of person who sets other people on fire. into world religions, ethics, philosophy, feminism. wasn't hesitant to give us the stark statistics about the state of most of the world's quality of life and what greedy bastards we are (but did it in a way that it revealed itself to us instead of her telling us off). has her own farm where she raises livestock for consumption. received a major award the year i had her class because she is that awesome. also had us do community service as part of our class even though it was a 400 level capstone! i can't figure out her enneagram.
writing prof, ESTJ -- she was talkative and witty, blunt and quirky. we had a love/hate relationship, since she was very much the enneagram 1 STJ perfectionistic hardliner and i was (at the time) a loosey-goosey ENFP freshman. i would get annoyed at her because she would micromanage bizarre things like the location of the classroom doorstop and she would get annoyed at me because i couldn't stick to a schedule to save my life. but we had a great mental connection, and in her later classes we would have an excellent time brainstorming together. she was also very humanistic and idealistic, but expressed through STJness, which was really interesting.
anthropology prof, ISFP -- really sweet, softspoken, kind, and very into what it means to be a human being. she opened me to a world more unified than the one i had already pictured, which is pretty incredible considering that my dominant Ne is a connecting function. somehow she resonated with me in a way that i could see through her eyes for little bits at a time. halfway through her career she had a major debilitating accident and instead of turning elsewhere she dove into the culture of disability and became a voice and mirror for the disabled. suspect 9w1.
child psych prof, INFJ -- i could not stand this bitch! i fully admit i am awkward communicating with INFJs sometimes but she was definitely an ice queen. she'd do nasty things like assign 60 pages' worth of blurry PDFs the night before a lab and then storm out of the classroom when she found out none of us read the entire thing. or change a major exam date and not make allowances for taking the test at a different time if you already had 2 other tests scheduled for that day. she talked about children in a way that was a little too clinical for my personal tastes. my ENFJ friend who also took the class liked her, though. the prof was probably 1w9.
counseling prof, INFJ -- the epitome of a counselor; sensitive internally but neutral externally, deeply compassionate and with ample foresight. he taught us how to draw a person deeper and deeper into self-revelation and self-actualization. had the classic Ni gaze. definitely 9w1.
