I would say that Cambridge, Mass, for example (home to Harvard and MIT) is INTJ.
I was inspired by a recent poll on the Facebook application Stuff White People Like that asked, "What City does your Soul belong in?" The choices were San Francisco, CA, New York, NY and something weird like Tijuana.
Anyway, this led to some pondering. As an ISTJ, and native of New York, I don't feel like I "belong" in New York City for a number of reasons. (It's too dirty, too crowded, expensive, and people are rude.) My idea city is Seattle or Portland - green, efficient, clean, and friendly.
